Application guide for 25-ton solar system (unitized)  

DOE Green Energy (OSTI)

Arkla has developed a unitary solar system for air conditioning, heating and service hot water loads in commercial buildings of up to 25 tons cooling requirement. A semi-exploded view shows the basic elements of the Arkla system. These elements, listed below, are described in individual sections of the guide in sufficient detail to enable a competent designer to duplicate the Arkla unitary system in a site built system. The elements are: (1) collectors with summary procedure guide; (2) storage/receiver; (3) pumps/piping/valves; (4) controls; (5) chiller; (6) cooling tower; (7) gas boiler back-up; (8) central air handling unit; and (9) service and DHW. Any successful solar HVAC system requires careful analysis of the integration of the elements. This is particularly true due to the large year-round variation in the temperature of the solar HW available. Several items of this nature are discussed in the element sections. Consequently, the designer should review this entire guide before proceeding to individual elements particularly A and B. This guide presumes that the monthly (and design) hot water loads have been determined for the heating, cooling, and service-DHW water Btu requirements. In addition to these normal calculations, an hourly profile for a typical day each month should be made. The hourly profile is necessary to maximize the solar fraction for a given amount of collector surface in conjunction with the size of the storage system; that is, the coincidence, or lack of, sunshine to the instantaneous demands.

Solar hot water systems for the southeastern United States: principles and construction of breadbox water heaters  

DOE Green Energy (OSTI)

The use of solar energy to provide hot water is among the easier solar technologies for homeowners to utilize. In the Southeastern United States, because of the mild climate and abundant sunshine, solar energy can be harnessed to provide a household's hot water needs during the non-freezing weather period mid-April and mid-October. This workbook contains detailed plans for building breadbox solar water heaters that can provide up to 65% of your hot water needs during warm weather. If fuel costs continue to rise, the annual savings obtained from a solar water heater will grow dramatically. The designs in this workbook use readily available materials and the construction costs are low. Although these designs may not be as efficient as some commercially available systems, most of a household's hot water needs can be met with them. The description of the breadbox water heater and other types of solar systems will help you make an informed decision between constructing a solar water heater or purchasing one. This workbook is intended for use in the southeastern United States and the designs may not be suitable for use in colder climates.

Market potential for solar thermal energy supply systems in the United States industrial and commercial sectors: 1990--2030. Final report  

DOE Green Energy (OSTI)

This report revises and extends previous work sponsored by the US DOE on the potential industrial market in the United States for solar thermal energy systems and presents a new analysis of the commercial sector market potential. Current and future industrial process heat demand and commercial water heating, space heating and space cooling end-use demands are estimated. The PC Industrial Model (PCIM) and the commercial modules of the Building Energy End-Use Model (BEEM) used by the DOE`s Energy Information Administration (EIA) to support the recent National Energy Strategy (NES) analysis are used to forecast industrial and commercial end-use energy demand respectively. Energy demand is disaggregated by US Census region to account for geographic variation in solar insolation and regional variation in cost of alternative natural gas-fired energy sources. The industrial sector analysis also disaggregates demand by heat medium and temperature range to facilitate process end-use matching with appropriate solar thermal energy supply technologies. The commercial sector analysis disaggregates energy demand by three end uses: water heating, space heating, and space cooling. Generic conceptual designs are created for both industrial and commercial applications. Levelized energy costs (LEC) are calculated for industrial sector applications employing low temperature flat plate collectors for process water preheat; parabolic troughs for intermediate temperature process steam and direct heat industrial application; and parabolic dish technologies for high temperature, direct heat industrial applications. LEC are calculated for commercial sector applications employing parabolic trough technologies for low temperature water and space heating. Cost comparisons are made with natural gas-fired sources for both the industrial market and the commercial market assuming fuel price escalation consistent with NES reference case scenarios for industrial and commercial sector gas markets.

Solar trough systems  

DOE Green Energy (OSTI)

Trough systems predominate among today`s commercial solar power plants. All together, nine trough power plants, also called Solar Energy Generating Systems (SEGS), were built in the 1980s in the Mojave Desert near Barstow, California. These plants have a combined capacity of 354 megawatts (MW) and today generate enough electricity to meet the needs of approximately 500,000 people. Trough systems convert the heat from the sun into electricity. Because of their parabolical shape, troughs can focus the sun at 30--60 times its normal intensity on a receiver pipe located along the focal line of the trough. Synthetic oil captures this heat as the oil circulates through the pipe, reaching temperatures as high as 390 C (735 F). The hot oil is pumped to a generating station and routed through a heat exchanger to produce steam. Finally, electricity is produced in a conventional steam turbine. In addition to operating on solar energy the SEGS plants are configured as hybrids to operate on natural gas on cloudy days or after dark. Natural gas provides 25% of the output of the SEGS plants.

Solar dish/engine systems  

DOE Green Energy (OSTI)

Solar dish/engine systems convert the energy from the sun into electricity at a very high efficiency. Using a mirror array formed into the shape of a dish, the solar dish focuses the sun's rays onto a receiver. The receiver transmits the energy to an engine that generates electric power. Because of the high concentration ratios achievable with parabolic dishes and the small size of the receiver, solar dishes are efficient at collecting solar energy at very high temperatures. Tests of prototype systems and components at locations throughout the US have demonstrated net solar to electric conversion efficiencies as high as 30%. This is significantly higher than any other solar technology.

Laser system preset unit  

DOE Patents (OSTI)

An electronic circuit is provided which may be used to preset a digital display unit of a Zeeman-effect layer interferometer system which derives distance measurements by comparing a reference signal to a Doppler signal generated at the output of the interferometer laser head. The circuit presets dimensional offsets in the interferometer digital display by electronically inducing a variation in either the Doppler signal or the reference signal, depending upon the direction of the offset, to achieve the desired display preset.

Mathematical structure of unit systems  

E-Print Network (OSTI)

We investigate the mathematical structure of unit systems and the relations between them. Looking over the entire set of unit systems, we can find a mathematical structure that is called preorder (or quasi-order). For some pair of unit systems, there exists a relation of preorder such that one unit system is transferable to the other unit system. The transfer (or conversion) is possible only when all of the quantities distinguishable in the latter system are always distinguishable in the former system. By utilizing this structure, we can systematically compare the representations in different unit systems. Especially, the equivalence class of unit systems (EUS) plays an important role because the representations of physical quantities and equations are of the same form in unit systems belonging to an EUS. The dimension of quantities is uniquely defined in each EUS. The EUS's form a partially ordered set. Using these mathematical structures, unit systems and EUS's are systematically classified and organized as a hierarchical tree.

Solar heating system final design package  

DOE Green Energy (OSTI)

Contemporary Systems has taken its Series V Solar Heating System and developed it to a degree acceptable by local codes and regulatory agencies. The system is composed of the Series V warm air collector, the LCU-110 logic control unit and the USU-A universal switching and transport unit. The collector was originally conceived and designed as an integrated roof/wall system and provides a dual function in the structure. The collector serves both as a solar energy conversion system and as a structural weather resistant skin. The collector can be fabricated in any length from 12 to 24 feet. This provides maximum flexibility in design and installation. The LCU-110 control unit provides totally automatic control over the operation of the system. It receives input data from sensor probes in collectors, storage and living space. The logic is designed so as to make maximum use of solar energy and minimize use of conventional energy. The USU-A transport and switching unit is a high-efficiency air-handling system equipped with gear motor valves that respond to outputs from the control system. The fan unit is designed for maximum durability and efficiency in operation, and has permanently lubricated ball bearings and excellent air-handling efficiency.

Regional Per Capita Solar Electric Footprint for the United States  

DOE Green Energy (OSTI)

In this report, we quantify the state-by-state per-capita 'solar electric footprint' for the United States. We use state-level data on population, electricity consumption, economic activity and solar insolation, along with solar photovoltaic (PV) array packing density data to develop a range of estimates of the solar electric footprint. We find that the solar electric footprint, defined as the land area required to supply all end-use electricity from solar photovoltaics, is about 181 m2 per person in the United States. Two key factors that influence the magnitude of the state-level solar electric footprint include how industrial energy is allocated (based on location of use vs. where goods are consumed) and the assumed distribution of PV configurations (flat rooftop vs. fixed tilt vs. tracking). The solar electric footprint is about 0.6% of the total land area of the United States with state-level estimates ranging from less than 0.1% for Wyoming to about 9% for New Jersey. We also compare the solar electric footprint to a number of other land uses. For example, we find that the solar electric footprint is equal to less than 2% of the land dedicated to cropland and grazing in the United States.

Potential for supplying solar thermal energy to industrial unit operations  

DOE Green Energy (OSTI)

Previous studies have identified major industries deemed most appropriate for the near-term adoption of solar thermal technology to provide process heat; these studies have been based on surveys that followed standard industrial classifications. This paper presents an alternate, perhaps simpler analysis of this potential, considered in terms of the end-use of energy delivered to industrial unit operations. For example, materials, such as animal feed, can be air dried at much lower temperatures than are currently used. This situation is likely to continue while economic supplies of natural gas are readily available. However, restriction of these supplies could lead to the use of low-temperature processes, which are more easily integrated with solar thermal technology. The adoption of solar technology is also favored by other changes, such as the relative rates of increase of the costs of electricity and natural gas, and by energy conservation measures. Thus, the use of low-pressure steam to provide process heat could be replaced economically with high-temperature hot water systems, which are more compatible with solar technology. On the other hand, for certain operations such as high-temperature catalytic and distillation processes employed in petroleum refining, there is no ready alternative to presently employed fluid fuels.

Odyssey: a Solar System Mission  

E-Print Network (OSTI)

The Solar System Odyssey mission uses modern-day high-precision experimental techniques to test the laws of fundamental physics which determine dynamics in the solar system. It could lead to major discoveries by using demonstrated technologies. The mission proposes to perform a set of precision gravitation experiments from the vicinity of Earth to the outer Solar System. Its scientific objectives can be summarized as follows: i) test of the gravity force law in the Solar System up to and beyond the orbit of Saturn; ii) precise investigation of navigation anomalies at the fly-bys; iii) measurement of Eddington's parameter at occultations; iv) mapping of gravity field in the outer solar system and study of the Kuiper belt. To this aim, the Odyssey mission is built up on a main spacecraft, designed to fly up to 13 AU, with the following components: a) a high-precision accelerometer, with bias-rejection system, measuring the deviation of the trajectory from the geodesics; b) Ka-band transponders, as for Cassini, for a precise range and Doppler measurement up to 13 AU, with additional VLBI equipment; c) optional laser equipment, which would allow one to improve the range and Doppler measurement. In this baseline concept, the main spacecraft is designed to operate beyond the Saturn orbit, up to 13 AU. It experiences multiple planetary fly-bys at Earth, Mars or Venus, and Jupiter. The cruise and fly-by phases allow the mission to achieve its baseline scientific objectives (i) to iii) in the above list). In addition to this baseline concept, the Odyssey mission proposes the release of the Enigma radio-beacon at Saturn, allowing one to extend the deep space gravity test up to at least 50 AU, while achieving the scientific objective of a mapping of gravity field in the outer Solar System.

Passive-solar design manual for the United States Navy  

DOE Green Energy (OSTI)

A passive solar design manual for single-family detached residences and dormitory-type buildings is being developed. The design procedure employed in the manual is a simplification of the original monthly solar load ratio (SLR) method. The new SLR correlations involve a single constant for each system. The correlation constant appears as a scale factor permitting the use of a universal performance curve for all passive systems. Furthermore, by providing location-dependent correlations between the annual solar heating fraction (SHF)* and the minimum monthly SHF, we have eliminated the need to perform an SLR calculation for each month of the heating season.

Land-Use Requirements for Solar Power Plants in the United States  

DOE Green Energy (OSTI)

This report provides data and analysis of the land use associated with utility-scale ground-mounted solar facilities, defined as installations greater than 1 MW. We begin by discussing standard land-use metrics as established in the life-cycle assessment literature and then discuss their applicability to solar power plants. We present total and direct land-use results for various solar technologies and system configurations, on both a capacity and an electricity-generation basis. The total area corresponds to all land enclosed by the site boundary. The direct area comprises land directly occupied by solar arrays, access roads, substations, service buildings, and other infrastructure. As of the third quarter of 2012, the solar projects we analyze represent 72% of installed and under-construction utility-scale PV and CSP capacity in the United States.

Analysis of hybrid solar systems  

DOE Green Energy (OSTI)

This study uses the TRNSYS simulation program to evaluate the performance of active charge/passive discharge solar systems with water as the working fluid. This design was introduced in the Village Homes development in Davis, Calif., and is currently being used by Trident Energy Systems in Davis. TRNSYS simulations are used to evaluate the heating performance and cooling augmentation provided by systems in several climates. The results of the simulations are used to develop a simplified analysis tool similar to the F-chart and Phi-bar procedures used for active systems. This tool, currently in a preliminary stage, should provide the designer with quantitative performance estimates for comparison with other passive, active, and nonsolar heating and cooling designs.

Solar heating of integrated greenhouse-animal shelter systems  

SciTech Connect

An analytical procedure to determine the effectiveness of greenhouses as solar collectors was presented. This procedure was used to predict the effect of several construction parameters on solar radiation input to greenhouses. The orientation of the greenhouse was found to be the most effective construction parameter controlling solar radiation input to greenhouses. The effective albedo of the plant canopy was also found to be a significant factor. A new solar greenhouse design, suitable for high latitude regions was developed. The results showed that an internal solar collector could be incorporated as an integral part of the greenhouse design. The concept developed could be used as a free-standing greenhouse or in a combination with livestock building. The efficiency of the solar input was investigated for the conventional and the shed greenhouses, both as a free-standing unit and a greenhouse-animal shelter system, using computer simulation analyses. The results indicated that the efficiency of solar input is highly dependent on location; the effect of location on the shed type design is more profound. A typical case of a greenhouse-hog barn production system was investigated using computer simulation analyses. The results showed that such a food production system achieves a significant reduction in conventional fuel consumption due to both animal waste heat recovery and solar energy utilization.

Corrosion and scaling in solar heating systems  

SciTech Connect

Corrosion, as experienced in solar heating systems, is described in simplistic terms to familiarize designers and installers with potential problems and their solutions. The role of a heat transfer fluid in a solar system is briefly discussed, and the choice of an aqueous solution is justified. The complexities of the multiple chemical and physical reactions are discussed in order that uncertainties of corrosion behavior can be anticipated. Some basic theories of corrosion are described, aggressive environments for some common metals are identified, and the role of corrosion inhibitors is delineated. The similarities of thermal and material charactristics of a solar system and an automotive cooling system are discussed. Based on the many years of experience with corrosion in automotive systems, it is recommended that similar antifreezes and corrosion inhibitors should be used in solar systems. The importance of good solar system design and fabrication is stressed and specific characteristics that affect corrosion are identified.

Optimization of a solar cooling system with interior energy storage  

Science Conference Proceedings (OSTI)

This paper focuses on the optimization of the performance of a solar absorption cooling system composed by four units with interior energy storage. A full dynamic simulation model that includes the solar collector field, the absorption heat pump system and the building load calculation has been developed. It has been applied to optimize the coupling of a system based on this new technology of solar powered absorption heat pump, to a bioclimatic building recently constructed in the Plataforma Solar de Almeria (PSA) in Spain. The absorption heat pump system considered is composed by four heat pumps that store energy in the form of crystallized salts so that no external storage capacity is required. Each heat pump is composed of two separate barrels that can charge (store energy from the solar field) and discharge (deliver heat or cold to the building) independently. Different configurations of the four units have been analysed taking into account the storage possibilities of the system and its capacity to respond to the building loads. It has been shown how strong the influence of the control strategies in the overall performance is, and the importance of using hourly simulations models when looking for highly efficient buildings.

Dish/engine systems use a parabolic dish of mirrors to direct and concentrate sunlight onto a central engine that produces electricity. The two major parts of the system are the solar concentrator and the power conversion unit. Solar Concentrator Illustration of a dish/engine power plant. Sunlight is shown reflecting off the large dish-shaped concentrator and onto the mounted power conversion unit to generate electricity that is fed into the power grid.

Solar Deployment System (SolarDS) Model: Documentation and Sample Results  

DOE Green Energy (OSTI)

The Solar Deployment System (SolarDS) model is a bottom-up, market penetration model that simulates the potential adoption of photovoltaics (PV) on residential and commercial rooftops in the continental United States through 2030. NREL developed SolarDS to examine the market competitiveness of PV based on regional solar resources, capital costs, electricity prices, utility rate structures, and federal and local incentives. The model uses the projected financial performance of PV systems to simulate PV adoption for building types and regions then aggregates adoption to state and national levels. The main components of SolarDS include a PV performance simulator, a PV annual revenue calculator, a PV financial performance calculator, a PV market share calculator, and a regional aggregator. The model simulates a variety of installed PV capacity for a range of user-specified input parameters. PV market penetration levels from 15 to 193 GW by 2030 were simulated in preliminary model runs. SolarDS results are primarily driven by three model assumptions: (1) future PV cost reductions, (2) the maximum PV market share assumed for systems with given financial performance, and (3) PV financing parameters and policy-driven assumptions, such as the possible future cost of carbon emissions.

Solar-wind hybrid systems are discussed. It is shown that there are large areas in the United States where solar and wind resources are comparable in magnitude and there are diurnal and seasonal complementarities which offer the potential for cost-effective hybrid systems. There are also distinct engineering features of the two conversion technologies. Electric power generation from wind is straightforward and cost-effective, whereas solar thermal conversion to generate heat is more cost-effective than to generate electricity. Examples of hybrid systems utilizing these features in total energy applications are presented.

Proposal for an Adsorption Solar-Driven Air-Conditioning Unit for Public Offices  

E-Print Network (OSTI)

A simple prototype air conditioning unit driven entirely by solar energy is proposed aiming at replacing the conventional vapor compression air conditioning systems which are reasonable for the global warming. The proposed model is supposed to be used in conditioning the governmental offices during the working hours in the weekdays when both the sunshine and the need for air-conditioning reach their maximum levels at the same instance. Solar adsorption refrigeration devices have no moving parts consequently they are noiseless, non-corrosive, cheap to maintain, long lasting in addition to being environmentally friendly with zero ozone depletion as well as zero global warming potentials. For these reasons, the research activities are of increasing interest in this aspect in order to provide optimum solutions for the crucial points that impede making these systems capable to meet the criteria for commercialization.

Technical and Economic Analysis of Solar Cooling Systems in a Hot and Humid Climate  

E-Print Network (OSTI)

The aim of this paper is to promote efficient and cost effective implementation of advanced solar cooling systems and techniques for the hot and humid climates cities in the United States. After an introduction of basic principles, the development history and recent progress in solar cooling technologies are reported. Nevertheless, the economics of solar energy systems are particularly complex with much inevitable uncertainty due to several factors. In this paper, a simplified comprehensive economic optimization model is developed to determine whether a particular solar system is economically advantageous for a particular project. This model explains and illustrates with simple, but realistic examples the use of life-cycle cost analysis and benefit-cost analysis to evaluate and compare the economic efficiency of the solar cooling system. Consequently, under appropriate conditions, solar or solar-assisted air conditioning systems may be reasonable alternatives to conventional air-conditioning systems in a hot and humid climate.

Solar photovoltaic/thermal residential systems  

DOE Green Energy (OSTI)

The results of a conceptual design study using computer simulations to determine the physical and economic performance of combined photovoltaic/thermal collector heat-pump solar systems for a single-family residence are presented. Economic analyses are based upon projected costs for a 1986 system installation. The results show that PV/T collector systems can be economically competitive for a cold climate residence, that systems employing on-site electrical storage batteries are not economically competitive with utility-interactive systems, and that an ambient-air-source heat-pump system has a lower life-cycle cost than a solar-source heat-pump system.

Then isotope ratios in meteorites, interplanetary dust and gas, and the sun itself were found to differ from those on Earth. Planetary researchers like UC San Diego's Mark Thiemens and his colleagues, working with Musa Ahmed of the Chemical Sciences Division, are now using the Chemical Dynamics Beamline at the Advanced Light Source to study these "mass-independent" effects and their origins in the chemical processes of the early solar system.

Electric utilities and residential solar systems  

DOE Green Energy (OSTI)

The long-run incremental cost (LRIC) of providing electricity for solar heating and hot water systems is estimated for three utilities using a utility capacity expansion model and compared to the cost of providing electricity to electric-only systems. All investment, fuel and operating costs are accounted for. Hot water systems and combined heating and hot water systems are analyzed separately. It is found that the LRIC for solar backup is no more than the LRIC of electricity used for purely electric heating and hot water devices and also no more than the incremental cost of normal load growth. For the three utilities studied, there appears to be little basis for rate distinctions between solar devices using electric backup and electric-only heating and hot water devices. Off-peak storage heating and hot water devices have a much lower LRIC than the standard systems; again, there appears to be no basis for distinguishing between solar and electric off-peak devices. Compared to average cost pricing, incremental cost pricing offers considerable benefits to customers using solar and electric heat and hot water, especially if a separate lower rate is adopted for off-peak storage devices; these benefits can amount to several hundred dollars per year. Substantial savings in the use of oil and gas fuels can be achieved if residences using these fuels convert to solar systems, savings not necessarily achievable by a shift, instead, to electric systems.

Cutting Industrial Solar System Costs in Half  

E-Print Network (OSTI)

While there are technical, social, environmental and institutional barriers to the widespread use of solar systems, the principle barrier is economic. For commercial and industrial firms to turn to this alternate energy source, the first cost must be sharply reduced so that the annual savings that are achievable will provide an attractive return on the incremental investment. This paper discusses one proven method of combining the energy efficiency of high temperature industrial heat pumps with solar collectors that result in an installed first cost that approximates one half of that of conventional solar systems. This technology is now available for producing up to 220 F hot water for industrial process heat, space heating, and service hot water heating. The basic principles of the technology are reviewed, including the typical operating characteristics of the industrial heat pumps and the solar collectors, plus the generic application schematics comparing this approach with conventional solar collector only systems. Several case histories are reviewed, including an industrial plant, townhouse project, and hospital. Not only is a lower first cost demonstrated, but the combination uses small solar arrays, ideal where roof area is limited, and use less expensive solar collectors.

Hybrid photovoltaic/thermal solar energy system  

DOE Green Energy (OSTI)

Heating and cooling systems that use hybrid solar energy collectors (combination photovoltaic-thermal) have the potential for considerable energy savings, particularly when the system includes a heat pump. Economic evaluations show that photovoltaic systems are potentially most economical, but results depend critically on future collector costs as well as energy prices. Results are based on a specially developed computer program that predicted the total auxiliary energy required for five different solar heating/cooling systems. Performance calculations for a modeled residence and small office building were made using meteorological data from four geographic locations. Annual system costs were also calculated.

The Birth Environment of the Solar System  

E-Print Network (OSTI)

This paper reviews our current understanding of the possible birth environments of our Solar System. Since most stars form within groups and clusters, the question becomes one of determining the nature of the birth aggregate of the Sun. This discussion starts by reviewing Solar System properties that provide constraints on our environmental history. We then outline the range of star-forming environments that are available in the Galaxy, and discuss how they affect star and planet formation. The nature of the solar birth cluster is constrained by many physical considerations, including radiation fields provided by the background environment, dynamical scattering interactions, and by the necessity of producing the short-lived radioactive nuclear species inferred from meteoritic measurements. Working scenarios for the solar birth aggregate can be constructed, as discussed herein, although significant uncertainties remain.

Solar-Electric Dish Stirling System Development  

DOE Green Energy (OSTI)

Electrical power generated with the heat from the sun, called solar thermal power, is produced with three types of concentrating solar systems - trough or line-focus systems; power towers in which a centrally-located thermal receiver is illuminated with a large field of sun-tracking heliostats; and dish/engine systems. A special case of the third type of system, a dish/Stirling system, is the subject of this paper. A dish/Stirling system comprises a parabolic dish concentrator, a thermal receiver, and a Stirling engine/generator located at the focus of the dish. Several different dish/Stirling systems have been built and operated during the past 15 years. One system claims the world record for net conversion of solar energy to electric power of 29.4%; and two different company`s systems have accumulated thousands of hours of on-sun operation. Due to de-regulation and intense competition in global energy markets as well as the immaturity of the technology, dish/Stirling systems have not yet found their way into the marketplace. This situation is changing as solar technologies become more mature and manufacturers identify high-value niche markets for their products. In this paper, I review the history of dish/Stirling system development with an emphasis on technical and other issues that directly impact the Stirling engine. I also try to provide some insight to the opportunities and barriers confronting the application of dish/Stirling in power generation markets.

Using RPS Policies to Grow the Solar Market in the United States  

SciTech Connect

The market for photovoltaics in the United States remains small relative to the nation's solar resource potential. Nonetheless, annual grid-connected PV installations have grown from just 4 MW in 2000 to over 100 MW in 2006, fast enough to the catch the attention of the global solar industry. The state of California deserves much of the credit for this growth. The State's historical rebate programs resulted in roughly 75% of the nation's grid-connected PV additions from 2000 through 2006 being located in California, and the $3 billion California Solar Initiative will ensure that the State remains a mainstay of the US solar industry for years to come. But California is not the only market for solar in the US; other states have recently developed policies that may rival those of the western state in terms of future growth potential. In particular, 25 states, as well as Washington, D.C., have established renewables portfolio standards (RPS), sometimes called quota systems in Europe, requiring electricity suppliers in those states to source a minimum portion of their need from renewable electricity. (Because a national RPS is not yet in place, my focus here is on state policies). Under many of these state policies, solar is not expected to fare particularly well: PV installations simply cannot compete on cost or scale with large wind plants in the US, at least not yet. In response, an expanding list of states have established solar or distributed generation (DG) set-asides within their RPS policies, effectively requiring that some fraction of RPS-driven supply derive from solar energy. The popularity of set-asides for solar and/or DG has increased dramatically in recent years. Already, 11 states and D.C. have developed such RPS set-asides. These include states with outstanding solar resources, such as Nevada, Arizona, Colorado, and New Mexico, as well as areas where the solar resource is less robust, including North Carolina, Maryland, Pennsylvania, New Jersey, New York, New Hampshire, Delaware, and DC. Among those states with set-asides, two are restricted to PV applications, nine also allow solar-thermal electric to qualify, three allow solar heating and/or cooling to qualify, and three have broader renewable DG set-asides. The policies also differ in their targets and timeframes, whether projects must be located in-state, the application of cost caps, and the degree of oversight on how suppliers contract with solar projects. Only three of these states have more than two years of experience with solar or DG set-asides so far: Arizona, Nevada, and New Jersey. And yet, despite the embryonic stage of these policies, they have already begun to have a significant impact on the grid-connected PV market. From 2000-2006, 16% (or 48 MW) of grid-connected PV installations in the US occurred in states with such set-asides, a percentage that increases to 67% if one only considers PV additions outside of California. The importance of these programs is growing and will continue to expand. In fact, if one assumes (admittedly somewhat optimistically) that these policies will be fully achieved, then existing state solar or DG set-asides could result in 400 MW of solar capacity by 2010, 2,000 MW by 2015, and 6,500 MW by 2025. This equates to annual additions of roughly 100 MW through 2010, increasing to over 500 MW per year by 2015 and 700 MW per year by 2020. PV is not assured of all of this capacity, and will receive strong competition from solar-thermal electric facilities in the desert southwest. Nonetheless, set-asides in those states outside of the southwest will favor PV, and even some of the southwestern states have designed their RPS programs to ensure that PV fares well, relative to other forms of solar energy. Since 2000, Arizona and, more recently, New Jersey have represented the largest solar set-aside-driven PV markets. Even more-recent additions are coming from Colorado, Nevada, New York, and Pennsylvania. In the long-term, the largest markets for solar electricity are predicted to include New Jersey, Maryland,

This equates to annual additions of roughly 100 MW through 2010, increasing to over 500 MW per year by 2015 and 700 MW per year by 2020. PV is not assured of all of this capacity, and will receive strong competition from solar-thermal electric facilities in the desert southwest. Nonetheless, set-asides in those states outside of the southwest will favor PV, and even some of the southwestern states have designed their RPS programs to ensure that PV fares well, relative to other forms of solar energy. Since 2000, Arizona and, more recently, New Jersey have represented the largest solar set-aside-driven PV markets. Even more-recent additions are coming from Colorado, Nevada, New York, and Pennsylvania. In the long-term, the largest markets for solar electricity are predicted to include New Jersey, Maryland, Arizona, and P

Residential passive solar systems: regional sensitivity to system performance costs, and alternative prices  

DOE Green Energy (OSTI)

The economic potential of two passive space heating configurations are analyzed. These are a masonry thermal storage wall (Trombe) and a direct gain system - both with night insulation. A standard tract home design for each of the two passive systems is being used throughout the analysis to allow interregional comparisons. The economic performance of these two systems is evaluated on a regional basis (223 locations) throughout the United States. For each of the two conventional energy types considered (electricity and natural gas), sensitivity analysis is conducted to determine the impact of alternative fuel price escalation rates and solar costs upon feasibility of the two solar systems. Cost goals for solar system prices are established under one set of future fuel prices and stated economic conditions. (MOW)

Utility market and requirements for a solar thermophotovoltaic system  

Science Conference Proceedings (OSTI)

There is a growing need for clean affordable electric power generation in both the U.S. and internationally and solar thermophotovoltaic (STPV) can meet the needs of this market. This paper investigates the utility grid market applicable to a solar thermophotovoltaic power generating system. It finds that a large international electrical market and a smaller U.S. electrical market exist today but the U.S. market will grow by the year 2005 to a level that would easily support the high production level required for solar systems to be cost effective. Factors which could influence this market and the system characteristics considered by utilities in selecting future power systems such as levelized energy cost, dispatchability, environmental, etc., for both the grid and remote market are discussed. The main competition for this market and the operating performance of this competition are described. A conceptual design of a STPV power system is presented, the operation is described, and how the performance meets the utility requirements is discussed. The relationship between the cost of the TPV conversion unit and the system efficiency of the STPV system is given for both the grid and remote markets that it must meet in order to be competitive. {copyright} {ital 1996 American Institute of Physics.}

Solar evacuated tube collector: absorption chiller systems simulation  

DOE Green Energy (OSTI)

A residential air conditioning system incorporating an Arkla Solaire absorption chiller and Corning Glass Works evacuated tube collectors is simulated and the design parameters studied. Mathematical models of the evacuated tube collector and Arkla absorption chiller based on experimental results of the components have been created and incorporated into a complete system simulation. The chiller model includes transient start-up effects and the evacuated tube collector model includes numerous optical effects. A standard Arkla chiller in a humid climate (Washington, D.C.) and an Arkla unit with a modified charge for dry climates (Fort Collins, Colorado) are studied. Design parameters considered include the use of chilled water storage to reduce transient start-up effects of the absorption unit, the effects of removing heat from the solar system for preheating service hot water, the use of a tempering valve to prevent over-firing of the absorption unit in dry climates, and solar storage sizing considerations. The study results and conclusions are used to specify a cooling system design.

System integration issues of residential solar photovoltaic systems  

DOE Green Energy (OSTI)

The objective of this study is to evaluate the economic effects of residential solar PV systems on the utility's revenue, capacity, and energy requirements from the electric utility's perspective and to estimate the price that it might pay for surplus energy compared to what it would charge for deficits. The power and energy generated by the solar PV systems reduce the capital and operating costs that would otherwise be incurred by the utility. These avoided costs suggest what the utility might pay for surplus solar PV energy. The avoided costs are evaluated under three integration hypotheses, namely: (1) the utility has no system storage, (2) the utility has system storage, and (3) the solar PV systems are supported by dedicated storage devices, the purpose of which is to minimize sales to and purchases from the utility. Findings are reported in detail. (WHK)

Effect of solar-data errors on the performance and economics of solar systems  

Science Conference Proceedings (OSTI)

An analytical framework is presented that relates the errors in solar data to their effect on calculations of the performance and economics of certain solar systems. The analysis applies to systems in which the performance is expressed as the fraction (the so-called solar fraction) of a specified energy load that is supplied by solar energy. A set of dimensionless parameters is presented that describes the sensitivity of the predicted performance and costs to errors in the solar radiation data. A simple, heuristic, model is used to illustrate the basic points of the analysis. A solar heating system for a building of conventional construction is taken as a more realistic case study.

Prototype Energy Retrieval and Solar (PERS) System : Final Report.  

DOE Green Energy (OSTI)

The PERS System, which provides both heating and cooling for the substation Control House, has several different modes of operation. During the winter, heat from the transformer is recovered by a heat pump and is transferred to water circulating through a fan coil unit in the Control House forced air system. In addition, banks of tubular collectors mounted on the roof of the Control House can provide direct solar heating. During the summer, the solar collector array is used to drive a 15-ton absorption air conditioner which cools water in a 4300-gallon storage tank. Mechanical difficulaties were encountered, performance of components was not always satisfactory, and a need for modifications in the system emerged. During the winter testing period in December 1978, the heat recovery system performed with an average Coefficient of Performance (COP) of 2.75, as compared to the design goal of 4.6. The absorption chiller, however, performed quite well during the summer testing period in August, 1978. The coefficient of performance ranged from 0.598 to 0.622 on a daily basis, comparing favorably with the anticipated goal of a COP of 0.74. The overall solar-assisted absorption chiller system performed with a COP ranging from 2.80 to 3.57, with the absorption chiller functioning at even relatively low collector temperatures.

SIMULATION OF A SOLAR ABSORPTION COOLING SYSTEM  

E-Print Network (OSTI)

This paper describes the dynamic modeling of a solar absorption cooling plant that will be built for both research and demonstration purposes by the end of 2007. The synchronizing of cooling loads with solar radiation intensity is an important advantage when utilizing solar energy in air conditioning in buildings. The first part of this work deals with the dynamic modeling of an evacuated tube collector. A field of these collectors feed a single-effect absorption chiller of 35 kW nominal cooling capacity. The simulation model has been done in a modular way under TRNSYS16. In a second part, simulation and optimization of the system has been investigated in order to determine the effect of several parameters (collector area, tank volume...) on chiller performance.

Nonlinear Resonances in the Solar System  

E-Print Network (OSTI)

Orbital resonances are ubiquitous in the Solar system. They play a decisive role in the long term dynamics, and in some cases the physical evolution, of the planets and of their natural satellites, as well as the evolution of small bodies (including dust) in the planetary system. The few-body gravitational problem of hierarchical planetary-type systems allows for a complex range of dynamical timescales, from the fast orbital periods to the very slow orbit precession rates. The interaction of fast and slow degrees of freedom produces a rich diversity of resonance phenomena. Weak dissipative effects --- such as tides or radiation drag forces --- also produce unexpectedly rich dynamical behaviors. This paper provides a mostly qualitative discussion of simple dynamical models for the commonly encountered orbital resonance phenomena in the Solar system.

A control system is being developed that will be capable of operating solar heating and cooling systems covering a wide range of configurations, and using different operating strategies that may be optimal for different climatic regions. To insure widespread applicability of the control system, it is being designed to allow for modification for operating with essentially all practical heating and cooling system configurations and control algorithms simply by interchange of replaceable modules in the circuitry. An experimental heating and cooling system, the main purpose of which is to allow testing and exercise of the controller, was designed so that it could be operated in these various configurations.

Receiver System: Lessons Learned From Solar Two  

DOE Green Energy (OSTI)

The Boeing Company fabricated the Solar Two receiver as a subcontractor for the Solar Two project. The receiver absorbed sunlight reflected from the heliostat field. A molten-nitrate-salt heat transfer fluid was pumped from a storage tank at grade level, heated from 290 to 565 C by the receiver mounted on top of a tower, then flowed back down into another storage tank. To make electricity, the hot salt was pumped through a steam generator to produce steam that powered a conventional Rankine steam turbine/generator. This evaluation identifies the most significant Solar Two receiver system lessons learned from the Mechanical Design, Instrumentation and Control, Panel Fabrication, Site Construction, Receiver System Operation, and Management from the perspective of the receiver designer/manufacturer. The lessons learned on the receiver system described here consist of two parts: the Problem and one or more identified Solutions. The appendix summarizes an inspection of the advanced receiver panel developed by Boeing that was installed and operated in the Solar Two receiver.

Wind energy/geothermic/solar heating system. Final report  

SciTech Connect

I've observed three distinct ''camps'' of renewable energy resources; WIND, Geothermic, and Solar. None of the three are completely adequate for the NE by themselves. I observe little effort to combine them to date. My objective has been to demonstrate that the three can be combined in a practical system. To mitagate the high cost and poor payback for individual residences, I believe neighborhoods of 4 to 5 homes, apartment complexes or condominiums could form an Energy Association alloting a piece of ground (could be a greenbelt) which would contain the well or wells, solar boosted underground water storage and the Solar banks. These are the high cost items which could be prorated and ammortized by the Association. Easements would permit each residence underground insulated water lines for individual heat pump conversions to existing forced air furnaces. Where regulations permit, an individual home could erect his own windmill to belt drive his freon compressor. With or without the optional windmill the water to freon heat pump with its solar boosts on the well water, will enjoy COP's (coefficient of Performances or times better than electric resistance heat) beyond anything on the market today. In a neighborhood energy association, all trenching could be done together all plumbing could be one contract and they could qualify for quantity discounts on heat pump units, chillers and components and installation.

Design and operation of solar thermal heat transfer systems  

Science Conference Proceedings (OSTI)

The importance of heat transfer systems in the collection and use of solar energy is discussed. The success or failure of many solar energy systems has been determined by the design of the heat transfer system. This report includes a short summary of some of the DOE sponsored solar industrial process heat sites. From the design, construction, and operation of these systems many lessons were learned which will be important to designers and potential users of solar thermal systems. Also included is a discussion of solar collector foundation over-design that has increased the collector system costs.

Tracking Solar Energy Conersion Unit Adapted For Field Assembly  

DOE Patents (OSTI)

A modular solar energy collector having elongated V-shaped side walls formed by a pair of coplanar panels for each side wall. The upper panels, occupying most of the wall area are diffusely reflective, but the lower panels are specularly reflective. A Fresnel lens, having a snap fit relation to the side walls focuses some light on the lower specularly reflective panels which direct light to the solar cells at the base of the V-shaped walls. A heat sink provides support for the two panels with two opposed, upwardly extending wings terminating in opposed linear clips located near the lengthwise seam of the coplanar panels, each clip holding two coplanar panels in parallel alignment. The clips not only provide support for the panels, but also transfer heat to the remainder of the heat sink. The clips are shaped so that edges of the panels engage each clip by a snap fit, outside of the clip in one embodiment and inside of the clip in another embodiment. End caps are also formed with structures which snap to the wall panels. Since all junctions of components snap together, the collector of the present invention is easily assembled without specialized tools. Using side walls which are only partly specularly reflective permits a large angle of acceptance, yet provides an economical wall design because the entire wall need not be specularly reflective.

Polarimetric Remote Sensing of Solar System Objects  

E-Print Network (OSTI)

This book outlines the basic physical principles and practical methods of polarimetric remote sensing of Solar System objects and summarizes numerous advanced applications of polarimetry in geophysics and planetary astrophysics. In the first chapter we present a complete and rigorous theory of electromagnetic scattering by disperse media directly based on the Maxwell equations and describe advanced physically based modeling tools. This is followed, in Chapter 2, by a theoretical analysis of polarimetry as a remote-sensing tool and an outline of basic principles of polarimetric measurements and their practical implementations. In Chapters 3 and 4, we describe the results of extensive ground-based, aircraft, and spacecraft observations of numerous Solar System objects (the Earth and other planets, planetary satellites, Saturn's rings, asteroids, trans-Neptunian objects, and comets). Theoretical analyses of these data are used to retrieve optical and physical characteristics of planetary surfaces and atmospheres...

Dark matter chaos in the Solar System  

E-Print Network (OSTI)

We study the capture of galactic dark matter particles in the Solar System produced by rotation of Jupiter. It is shown that the capture cross section is much larger than the area of Jupiter orbit being inversely diverging at small particle energy. We show that the dynamics of captured particles is chaotic and is well described by a simple symplectic dark map. This dark map description allows to simulate the scattering and dynamics of $10^{14}$ dark matter particles during the life time of the Solar System and to determine dark matter density profile as a function of distance from the Sun. The mass of captured dark matter in the radius of Neptune orbit is estimated to be $2 \\cdot 10^{15} g$. The radial density of captured dark matter is found to be approximately constant behind Jupiter orbit being similar to the density profile found in galaxies.

Solar System constraints to nonminimally coupled gravity  

E-Print Network (OSTI)

We extend the analysis of Chiba, Smith and Erickcek \\cite{CSE} of Solar System constraints on $f(R)$ gravity to a class of nonminimally coupled (NMC) theories of gravity. These generalize $f(R)$ theories by replacing the action functional of General Relativity (GR) with a more general form involving two functions $f^1(R)$ and $f^2(R)$ of the Ricci scalar curvature $R$. While the function $f^1(R)$ is a nonlinear term in the action, analogous to $f(R)$ gravity, the function $f^2(R)$ yields a NMC between the matter Lagrangian density $\\LL_m$ and the scalar curvature. The developed method allows for obtaining constraints on the admissible classes of functions $f^1(R)$ and $f^2(R)$, by requiring that predictions of NMC gravity are compatible with Solar System tests of gravity. We apply this method to a NMC model which accounts for the observed accelerated expansion of the Universe.

We discuss the classical tests of general relativity in the presence of Rindler acceleration. Among these tests the perihelion shifts give the tightest constraints and indicate that the Pioneer anomaly cannot be caused by a universal solar system Rindler acceleration. We address potential caveats for massive test-objects. Our tightest bound on Rindler acceleration that comes with no caveats is derived from radar echo delay and yields |a|<3nm/s^2.

This paper introduces a solar energy heat-pump system and analyzes the thermoeconomics. The results show that the solar energy heat-pump system can be operated in different modes and used for room heating in winter and cooling in summer and/or heating a hot water supply. The results also show that the efficiency of the system's components and how the investment costs greatly affect the wide acceptability and use of the system. Solar energy is clean and renewable and having not to pay the solar energy costs, the solar energy heat-pump system is still attractive and will have a large market.

Solar power system requiring no active control device  

SciTech Connect

A solar power system has a photovoltaic array having a locus of peak power points for various insolation levels, a voltage-dependent variable resistance load such as a water electrolysis unit electrically connected to the array, and a demand-dependent variable resistance load such as a dc to ac inverter connected in parallel with the electrolysis unit. The electrolysis unit or other voltage-dependent variable resistance load has a voltage-current characteristic in which the operating point is displaced from the array's peak power point for most insolation levels. The characteristic is displaced towards higher voltage-lower current operating points. The inverter may move the operating point of the photovoltaic array toward its peak power point when the load requires power. The system may be designed so that the array operates within about 5 percent of its peak power point over a wide range of inverter power demands. A fuel cell may be connected in parallel with the array to provide power to the inverter at low insolation levels, at night or in low sunlight. The fuel cell may use the hydrogen produced by the electrolysis unit for fuel. The total photovoltaic power made available by the system of this invention is generally greater than 95 percent and often greater than 98 percent of the maximum power which the photovoltaic array may produce for many insolation levels.

Testing gravity law in the solar system  

E-Print Network (OSTI)

The predictions of General relativity (GR) are in good agreement with observations in the solar system. Nevertheless, unexpected anomalies appeared during the last decades, along with the increasing precision of measurements. Those anomalies are present in spacecraft tracking data (Pioneer and flyby anomalies) as well as ephemerides. In addition, the whole theory is challenged at galactic and cosmic scales with the dark matter and dark energy issues. Finally, the unification in the framework of quantum field theories remains an open question, whose solution will certainly lead to modifications of the theory, even at large distances. As long as those "dark sides" of the universe have no universally accepted interpretation nor are they observed through other means than the gravitational anomalies they have been designed to cure, these anomalies may as well be interpreted as deviations from GR. In this context, there is a strong motivation for improved and more systematic tests of GR inside the solar system, with the aim to bridge the gap between gravity experiments in the solar system and observations at much larger scales. We review a family of metric extensions of GR which preserve the equivalence principle but modify the coupling between energy and curvature and provide a phenomenological framework which generalizes the PPN framework and "fifth force" extensions of GR. We briefly discuss some possible observational consequences in connection with highly accurate ephemerides.

Break-Even Cost for Residential Solar Water Heating in the United States: Key Drivers and Sensitivities  

SciTech Connect

This paper examines the break-even cost for residential rooftop solar water heating (SWH) technology, defined as the point where the cost of the energy saved with a SWH system equals the cost of a conventional heating fuel purchased from the grid (either electricity or natural gas). We examine the break-even cost for the largest 1,000 electric and natural gas utilities serving residential customers in the United States as of 2008. Currently, the break-even cost of SWH in the United States varies by more than a factor of five for both electricity and natural gas, despite a much smaller variation in the amount of energy saved by the systems (a factor of approximately one and a half). The break-even price for natural gas is lower than that for electricity due to a lower fuel cost. We also consider the relationship between SWH price and solar fraction and examine the key drivers behind break-even costs. Overall, the key drivers of the break-even cost of SWH are a combination of fuel price, local incentives, and technical factors including the solar resource location, system size, and hot water draw.

Thermal Solar Energy Systems for Space Heating of Buildings  

E-Print Network (OSTI)

In this study, the simulation and the analysis of a solar flat plate collectors combined with a compression heat pump is carried out. The system suggested must ensure the heating of a building without the recourse to an auxiliary energy source in complement of this heating system. The system is used to heat a building using heating floor. The building considered is located in Constantine-East of Algeria (Latitude 36.28 N, Longitude 6.62 E, Altitude 689m). For the calculation, the month of February was chosen, which is considered as the coldest month according to the weather data of Constantine. The performances of this system were compared to the performances of the traditional solar heating system using solar collectors and an auxiliary heating load to compensate the deficit. In this case a traditional solar heating system having the same characteristics with regard to the solar collecting area and the volume of storage tank is used. It can be concluded that the space heating system using a solar energy combined with heat pump improve the thermal performance of the heat pump and the global system. The performances of the heating system combining heat pump and solar collectors are higher than that of solar heating system with solar collectors and storage tank. The heat pump assisted by solar energy can contribute to the conservation of conventional energy and can be competitive with the traditional systems of heating.

Commercial applications of solar total energy systems. Volume 4. Appendices. Final report. [Solar Total Energy System Evaluation Program (STESEP) code  

DOE Green Energy (OSTI)

A methodology has been developed by Atomics International under contract to the Department of Energy to define the applicability of solar total energy systems (STES) to the commercial sector (e.g., retail stores, shopping centers, offices, etc.) in the United States. Candidate STES concepts were selected to provide on-site power generation capability, as well as thermal energy for both heating and cooling applications.

Testing and design of solar cooling systems employing liquid dessicants  

DOE Green Energy (OSTI)

An open cycle liquid desiccant cooling system with cooling capacity of 3 tons (10.5 kW) a subject of research at Colorado State University. The system comprises two main units: the dehumidifier and the regenerator. Lithium bromide is the desiccant solution that dehumidifies the air stream during a counter-current, liquid-gas contacting in the packed tower. The regenerator concentrates the lithium bromide solution during a similar gas-liquid contacting using solar heated air with the only difference being that the direction of heat and mass transfer are reversed in this unit. The earlier studies conducted on the dehumidifier revealed significant departures from an energy balance closure. An attempt has been made to provide a realistic energy balance closure to the dehumidifier side. This has resulted in substantial re-calibration of the major instruments involved. Performance data of the entire system with the regenerator and dehumidifier operated in coupled mode have been presented. An optimization scheme to predict operating conditions suited for best performance of the two units, for varying ambient temperature and humidity to the dehumidifier, has been devised. 15 refs., 20 figs., 8 tabs.

Economic analysis of community solar heating systems that use annual cycle thermal energy storage  

DOE Green Energy (OSTI)

The economics of community-scale solar systems that incorporate a centralized annual cycle thermal energy storage (ACTES) coupled to a distribution system is examined. Systems were sized for three housing configurations: single-unit dwellings, 10-unit, and 200-unit apartment complexes in 50-, 200-, 400-, and 1000-unit communities in 10 geographic locations in the United States. Thermal energy is stored in large, constructed, underground tanks. Costs were assigned to each component of every system in order to allow calculation of total costs. Results are presented as normalized system costs per unit of heat delivered per building unit. These methods allow: (1) identification of the relative importance of each system component in the overall cost; and (2) identification of the key variables that determine the optimum sizing of a district solar heating system. In more northerly locations, collectors are a larger component of cost. In southern locations, distribution networks are a larger proportion of total cost. Larger, more compact buildings are, in general, less expensive to heat. For the two smaller-scale building configurations, a broad minima in total costs versus system size is often observed.

New passive solar cooking system. Final report  

SciTech Connect

The development of a solar cooking system which uses a phase change process to passively transfer heat from a collector to a cooker is presented. In the design of this cooking system steam is produced in the collector and then is used as the heat transfer fluid in the cooker. The most efficient use of the system is to heat food directly by condensing the steam onto the food, whereas a heat exchanger is necessary to heat an oven or a frying pan. A pressure cooker was successfully built and tested using the steam from the collector. Brief discussions on the collector design and performance, and heat storage phase change materials are provided. (BCS)

Thermal performance of space-cooling solar-energy systems in the National Solar Data Network  

DOE Green Energy (OSTI)

Results derived from analysis of data obtained from monitoring the operation of four solar energy cooling installations in the National Solar Data Network are presented. It is shown that chiller coefficients of performance (COP) on the order of 0.65 can be easily obtained with existing technology, provided the designer adequately matches the solar energy system to the absorption chiller. It is also shown that flat-plate, concentrating, and evacuated tube collectors may each be used successfully to operate absorption chillers in space cooling systems. The results show that appreciation for the systems engineering aspects of solar energy is extremely important to the development of a viable industry.

Concentrating Solar Deployment System (CSDS) -- A New Model for Estimating U.S. Concentrating Solar Power (CSP) Market Potential: Preprint  

DOE Green Energy (OSTI)

This paper presents the Concentrating Solar Deployment System Model (CSDS). CSDS is a multiregional, multitime-period, Geographic Information System (GIS), and linear programming model of capacity expansion in the electric sector of the United States. CSDS is designed to address the principal market and policy issues related to the penetration of concentrating solar power (CSP) electric-sector technologies. This paper discusses the current structure, capabilities, and assumptions of the model. Additionally, results are presented for the impact of continued research and development (R&D) spending, an extension to the investment tax credit (ITC), and use of a production tax credit (PTC). CSDS is an extension of the Wind Deployment System (WinDS) model created at the National Renewable Energy Laboratory (NREL). While WinDS examines issues related to wind, CSDS is an extension to analyze similar issues for CSP applications. Specifically, a detailed representation of parabolic trough systems with thermal storage has been developed within the existing structure.

Technical Potential of Solar Water Heating to Reduce Fossil Fuel Use and Greenhouse Gas Emissions in the United States  

DOE Green Energy (OSTI)

Use of solar water heating (SWH) in the United States grew significantly in the late 1970s and early 1980s, as a result of increasing energy prices and generous tax credits. Since 1985, however, expiration of federal tax credits and decreased energy prices have virtually eliminated the U.S. market for SWH. More recently, increases in energy prices, concerns regarding emissions of greenhouse gases, and improvements in SWH systems have created new interest in the potential of this technology. SWH, which uses the sun to heat water directly or via a heat-transfer fluid in a collector, may be particularly important in its ability to reduce natural gas use. Dependence on natural gas as an energy resource in the United States has significantly increased in the past decade, along with increased prices, price volatility, and concerns about sustainability and security of supply. One of the readily deployable technologies available to decrease use of natural gas is solar water heating. This report provides an overview of the technical potential of solar water heating to reduce fossil fuel consumption and associated greenhouse gas emissions in U.S. residential and commercial buildings.

DOE Green Energy (OSTI)

Progress is reported on the engineering design, fabrication, assembly, operation, economic analysis, and process support R and D for an Experimental Process System Development Unit (EPSDU) for producing semiconductor-grade silicon using the silane-to-silicon process. Most of the process related equipment has been ordered and is being fabricated. Equipment and building foundations have been completed at the EPSDU site, and all the steel was erected for the gantry. The switch gear/control building and the melter building will be completed during the next quarter. The data collection system design is progressing. Various computer programs are being written which will be used to convert electrical, pneumatic and other raw signals into engineering values. The free-space reactor development work was completed with a final 12-hour run in which the free-space reactor PDU ran flawlessly. Also, the quality control method development task was completed. Slim rods were grown from seed silicon rods for subsequent float zone operation and impurity characterization. An excellent quality epitaxial film was deposited on a silicon wafer. Both undoped ad doped films were deposited and the resistivity of the films have been measured. (WHK)

Potential of solar cooling systems for peak demand reduction  

DOE Green Energy (OSTI)

We investigated the technical feasibility of solar cooling for peak demand reduction using a building energy simulation program (DOE2.1D). The system studied was an absorption cooling system with a thermal coefficient of performance of 0.8 driven by a solar collector system with an efficiency of 50% with no thermal storage. The analysis for three different climates showed that, on the day with peak cooling load, about 17% of the peak load could be met satisfactorily with the solar-assisted cooling system without any thermal storage. A performance availability analysis indicated that the solar cooling system should be designed for lower amounts of available solar resources that coincide with the hours during which peak demand reduction is required. The analysis indicated that in dry climates, direct-normal concentrating collectors work well for solar cooling; however, in humid climates, collectors that absorb diffuse radiation work better.

Solar process heat technology in action: The process hot water system at the California Correctional Institution at Tehachapi  

DOE Green Energy (OSTI)

Solar process heat technology relates to solar thermal energy systems for industry, commerce, and government. Applications include water preheating and heating, steam generation, process hot air, ventilation air heating, and refrigeration. Solar process heat systems are available for commercial use. At the present time, however, they are economically viable only in niche markets. This paper describes a functioning system in one such market. The California Department of Corrections (CDOC), which operates correctional facilities for the state of California, uses a solar system for providing hot water and space heating at the California Correctional Institute at Tehachapi (CCI/Tehachapi). CCI/Tehachapi is a 5100-inmate facility. The CDOC does not own the solar system. Rather, it buys energy from private investors who own the solar system located on CCI/Tehachapi property; this arrangement is part of a long-term energy purchase agreement. United Solar Technologies (UST) of Olympia Washington is the system operator. The solar system, which began operating in the fall of 1990, utilizes 2677 m{sup 2} (28,800 ft{sup 2}) of parabolic through solar concentrators. Thermal energy collected by the system is used to generate hot water for showers, kitchen operations, and laundry functions. Thermal energy collected by the system is also used for space heating. At peak operating conditions, the system is designed to meet approximately 80 percent of the summer thermal load. 4 figs., 4 tabs.

Breakeven costs of storage in optimized solar energy systems  

DOE Green Energy (OSTI)

The results are described of an analysis of the breakeven cost, or value, of energy storage to solar energy systems. It is shown that the value of storage depends strongly both on solar fraction of the solar energy system in which the storage is employed, and on the cost of the collectors used in the system. Various strategies for dealing with this ambiguity are presented, and it is shown that for a broad class of technically and economically practical solar energy systems, storage costs need only be low enough to make a system employing very small amounts of storage practical. Reductions in cost of collectors will thereafter produce greater reductions in the total system costs or provide greater fuel displacement at constant total system cost than will reductions in the cost of storage, within limits discussed. The analysis makes use of a simple, accurate representation of solar energy system performance which may prove useful in other contexts.

Water use and supply concerns for utility-scale solar projects in the Southwestern United States.  

SciTech Connect

As large utility-scale solar photovoltaic (PV) and concentrating solar power (CSP) facilities are currently being built and planned for locations in the U.S. with the greatest solar resource potential, an understanding of water use for construction and operations is needed as siting tends to target locations with low natural rainfall and where most existing freshwater is already appropriated. Using methods outlined by the Bureau of Land Management (BLM) to determine water used in designated solar energy zones (SEZs) for construction and operations&maintenance, an estimate of water used over the lifetime at the solar power plant is determined and applied to each watershed in six Southwestern states. Results indicate that that PV systems overall use little water, though construction usage is high compared to O&M water use over the lifetime of the facility. Also noted is a transition being made from wet cooled to dry cooled CSP facilities that will significantly reduce operational water use at these facilities. Using these water use factors, estimates of future water demand for current and planned solar development was made. In efforts to determine where water could be a limiting factor in solar energy development, water availability, cost, and projected future competing demands were mapped for the six Southwestern states. Ten watersheds, 9 in California, and one in New Mexico were identified as being of particular concern because of limited water availability.

Supporting Solar Power in Renewables Portfolio Standards: Experience from the United States  

DOE Green Energy (OSTI)

Among the available options for encouraging the increased deployment of renewable electricity, renewables portfolio standards (RPS) have become increasingly popular. The RPS is a relatively new policy mechanism, however, and experience with its use is only beginning to emerge. One key concern that has been voiced is whether RPS policies will offer adequate support to a wide range of renewable energy technologies and applications or whether, alternatively, RPS programs will favor a small number of the currently least-cost forms of renewable energy. This report documents the design of and early experience with state-level RPS programs in the United States that have been specifically tailored to encourage a wider diversity of renewable energy technologies, and solar energy in particular. As shown here, state-level RPS programs specifically designed to support solar have already proven to be an important, albeit somewhat modest, driver for solar energy deployment, and those impacts are projected to continue to build in the coming years. State experience in supporting solar energy with RPS programs is mixed, however, and full compliance with existing requirements has not been achieved. The comparative experiences described herein highlight the opportunities and challenges of applying an RPS to specifically support solar energy, as well as the importance of policy design details to ensuring that program goals are achieved.

Solar-energy-system performance evaluation, April-August 1982, University of Minnesota Bookstore, Minneapolis, Minnesota  

DOE Green Energy (OSTI)

The solar system at the University of Minnesota Bookstore provided a total of 5% of the combined space heating and cooling load of 825 million Btu. The solar savings ratio, which accounts for operating energy used to collect solar energy, was 0.02. The fossil energy savings were 154.6 million Btu, equivalent to nine tons of coal, but there was an electrical energy expense of 19.2 million Btu (5620 kwh). The system had a net energy savings of $49.09 based on energy costs of $41.36 per ton of coal and 5.75 cents per kwh. Major energy flows to the heating and cooling subsystems are presented in the Energy Flow Diagram. In terms of solar energy utilization, the space cooling subsystem used 82 million Btu compared to 10.7 million Btu used in the space heating subsystem. The active solar energy system was retrofitted in 1979 on a relatively new earth-sheltered building which houses a bookstore, admissions and records facility. The building is 95% below ground for energy conservation and to preserve open space on the campus. Other energy conservation features are triple glazing on the windows, clerestories for daylighting and passive solar energy collection in winter, and a warm-air heat recovery system on the ventilation air. Due to the energy conservation features, the solar collection subsystem could be downsized and still provide large solar fractions. The solar collector array is comprised of six stationary units of 10 movable reflectors, each about 110 feet long and one foot wide. These glass mirrors concentrate sunlight onto a copper absorber tube receiver. Solar heated water from the storage tank or the collector array and water heated with auxiliary steam via a heat exchanger are delivered to a 147-ton absorption chiller for space cooling or to the heating coils for space heating.

DOE Green Energy (OSTI)

A Parabolic Dish-Electric Transport concept for dispersed solar thermal generation is considered. In this concept the power generated by 15 kWe Solar Generation Units is electrically collected in a large plant. Various approaches are possible for the conversion of mechanical shaft output of the heat engines to electricity. This study focuses on the Application of Field Modulated Generation System (FMGS) for that purpose. Initially the state-of-the-art of FMGS is presented, and the application of FMGS to dispersed solar thermal electric generation is investigated. This is followed by the definition of the control and monitoring requirements for solar generation system. Then comparison is made between FMGS approach and other options. Finally, the technology developmental needs are identified.

Solar system tests of brane world models  

E-Print Network (OSTI)

The classical tests of general relativity (perihelion precession, deflection of light, and the radar echo delay) are considered for the Dadhich, Maartens, Papadopoulos and Rezania (DMPR) solution of the spherically symmetric static vacuum field equations in brane world models. For this solution the metric in the vacuum exterior to a brane world star is similar to the Reissner-Nordstrom form of classical general relativity, with the role of the charge played by the tidal effects arising from projections of the fifth dimension. The existing observational solar system data on the perihelion shift of Mercury, on the light bending around the Sun (obtained using long-baseline radio interferometry), and ranging to Mars using the Viking lander, constrain the numerical values of the bulk tidal parameter and of the brane tension.

Solar Thermal Small Power Systems Study. Inventory of US industrial small electric power generating systems. [Less than 10 MW  

DOE Green Energy (OSTI)

This inventory of small industrial electric generating systems was assembled by The Aerospace Corporation to provide a data base for analyses being conducted to estimate the potential for displacement of these fossil-fueled systems by solar thermal electric systems no larger than 10 MW in rated capacity. The approximately 2100 megawatts generating capacity of systems in this category constitutes a potential market for small solar thermal and other solar electric power systems. The sources of data for this inventory were the (former) Federal Power Commission (FPC) Form 4 Industrial Ledger and Form 12-C Ledger for 1976. Table 1 alphabetically lists generating systems located at industrial plants and at Federal government installations in each of the 50 states. These systems are differentiated by type of power plant: steam turbine, diesel generator, or gas turbine. Each listing is designated as a power system rather than a power unit because the FPC Ledgers do not provide a means of determining whether more than one unit is associated with each industrial installation. Hence, the user should consider each listing to be a system capacity rating wherein the system may consist of one or more generating units with less than 10 MW/sub e/ combined rating. (WHK)

The storage tank is a 1500-gallon insulated steel tank which is located outside, above ground level. The space heating subsystem uses solar energy from storage and/or thermal energy from the natural-gas-fired boiler. The space cooling subsystem uses an absorption chiller to provide chilled water to the air-handling unit. As compared to the previous year, performance over the nine-month monitoring period was improved, based on overall solar contribution to the load. When compared to design values, the overall performance was poor. Overall solar fraction was an estimated 22% of the 220 million Btu system load. A total of 122 million Btu of solar energy was used by the space conditioning system. Auxiliary fossil fuel consumption was 608 million Btu, or 595,800 cubic feet of natural gas. Auxiliary thermal energy was a measured 68% of the auxiliary fossil fuel consumed. The solar savings ratio, a measure of the solar contribution to the load discounted by solar operating energy, averaged 19% during the analysis period. The previous year, the solar savings ratio was 16%.

Galileon forces in the Solar System  

E-Print Network (OSTI)

We consider the challenging problem of obtaining an analytic understanding of realistic astrophysical dynamics in the presence of a Vainshtein screened fifth force arising from infrared modifications of General Relativity. In particular, we attempt to solve -- within the most general flat spacetime galileon model -- the scalar force law between well separated bodies located well within the Vainshtein radius of the Sun. To this end, we derive the exact static Green's function of the galileon wave equation linearized about the background field generated by the Sun, for the minimal cubic and maximally quartic galileon theories, and then introduce a method to compute the general leading order force law perturbatively away from these limits. We also show that the same nonlinearities which produce the Vainshtein screening effect present obstacles to an analytic calculation of the galileon forces between closely bound systems within the solar system, such as that of the Earth and Moon. Within the test mass approximation, we deduce that a large enough quartic galileon interaction would suppress the effect on planetary perihelion precession below the level detectable by even the next-generation experiments.

BALDR-1: a solar thermal system simulation  

DOE Green Energy (OSTI)

A solar thermal system simulation (BALDR-1) was written in a modular fashion to facilitate expansion and modification. The flexibility of the simulation is derived, in part, from the use of three separate models to constitute the system simulation: FIELD, POWER, and ECON. Each model can be run independently, or they may be coupled and run as a set. The FIELD code models the optical and thermal performance of the collector field. It has separate optical and thermal performance routines for each generic collector type. Meteorological data is read in 15-minute or hourly increments. The POWER code models the performance of power conversion and storage components. It calculates the total thermal and/or electrical energy produced during the year for a set of plant configurations comprised of different collector field sizes, thermal storage sizes, and electrical storage sizes. The POWER code allows the selection of one of several control strategies in the dispatch of thermal and electrical storage. The ECON code calculates the initial capital cost of each power plant configuration modelled in POWER. This capital cost is combined with operations and maintenance costs to calculate a life-cycle busbar energy cost and simple payback period for each plant.

Solar photovoltaic systems for residences in the Northeast  

DOE Green Energy (OSTI)

Under sponsorship of the US Department of Energy, MIT Lincoln Laboratory is conducting a program to develop residential solar photovoltaic (PV) systems. The first phase of this activity involves the design, construction and testing of four prototype systems at the Northeast Residential Experiment Station. The systems employ roof-mounted photovoltaic arrays of 500 to 800 square feet which provide solar-generated electricity sufficient to cut in half the electrical demand of an energy-efficient, passive-solar residence. Construction of these systems will be complete by December 1980, and will be followed by a one-year test period.

Supply Curves for Solar PV-Generated Electricity for the United States  

DOE Green Energy (OSTI)

Energy supply curves attempt to estimate the relationship between the cost of an energy resource and the amount of energy available at or below that cost. In general, an energy supply curve is a series of step functions with each step representing a particular group or category of energy resource. The length of the step indicates how much of that resource is deployable or accessible at a given cost. Energy supply curves have been generated for a number of renewable energy sources including biomass fuels and geothermal, as well as conservation technologies. Generating a supply curve for solar photovoltaics (PV) has particular challenges due to the nature of the resource. The United States has a massive solar resource base -- many orders of magnitude greater than the total consumption of energy. In this report, we examine several possible methods for generating PV supply curves based exclusively on rooftop deployment.

Solar passive ceiling system. Final report. [Passive solar heating system with venetian blind reflectors and latent heat storage in ceiling  

DOE Green Energy (OSTI)

The construction of a 1200 square foot building, with full basement, built to be used as a branch library in a rural area is described. The primary heating source is a passive solar system consisting of a south facing window system. The system consists of: a set of windows located in the south facing wall only, composed of double glazed units; a set of reflectors mounted in each window which reflects sunlight up to the ceiling (the reflectors are similar to venetian blinds); a storage area in the ceiling which absorbs the heat from the reflected sunlight and stores it in foil salt pouches laid in the ceiling; and an automated curtain which automatically covers and uncovers the south facing window system. The system is totally passive and uses no blowers, pumps or other active types of heat distribution equipment. The building contains a basement which is normally not heated, and the north facing wall is bermed four feet high around the north side.

Development of an integrated heat pipe-thermal storage system for a solar receiver  

SciTech Connect

The Organic Rankine Cycle (ORC) Solar Dynamic Power System (SDPS) is one of the candidates for Space Station prime power application. In the low earth orbit of the Space Station approximately 34 minutes of the 94-minute orbital period is spent in eclipse with no solar energy input to the power system. For this period the SDPS will use thermal energy storage (TES) material to provide a constant power output. Sundstrand Corporation is developing a ORC-SDPS candidate for the Space Station that uses toluene as the organic fluid and LiOH as the TES material. An integrated heat-pipe thermal storage receiver system is being developed as part of the ORC-SDPS solar receiver. This system incorporates potassium heat pipe elements to absorb and transfer the solar energy within the receiver cavity. The heat pipes contain the TES canisters within the potassium vapor space with the toluene heater tube used as the condenser region of the heat pipe. During the insolation period of the earth orbit, solar energy is delivered to the heat pipe in the ORC-SDPS receiver cavity. The heat pipe transforms the non-uniform solar flux incident in the heat pipe surface within the receiver cavity to an essentially uniform flux at the potassium vapor condensation interface in the heat pipe. During solar insolation, part of the thermal energy is delivered to the heater tube and the balance is stored in the TES units. During the eclipse period of the orbit, the balance stored in the TES units is transferred by the potassium vapor to the toluene heater tube. 3 refs., 8 figs.

Investigation of a Novel Solar Assisted Water Heating System with Enhanced Energy Yield for Buildings  

E-Print Network (OSTI)

This paper presented the concept, prototype application, operational performance and benefits relating to a novel solar assisted water heating system for building services. It was undertaken through dedicated theoretical analysis, computer simulation and experimental verification. The unique characteristic of such system consists in the integrated loop heat pipe and heat pump unit (LHP-HP), which was proposed to improve solar photovoltaic (PV) generation, capture additional solar heat, and therefore enhance overall solar energy yield. The evaluation approaches derived from the first-law thermodynamics and the standard/hybrid system performance coefficients (COP/COPPV/T) were developed for the comprehensive assessments. Under the featured weather conditions, the mean electrical, thermal and overall energetic efficiencies of the module were tested around 9.12%, 38.13% and 47.25% respectively. Whilst the COP and COPPV/T values of entire system were measured at about 5.51 and 8.81 averagely. Moreover, a general comparison of this prototype system against the conventional solar/air energy systems was simply discussed.

The program is obtaining engineering data which may be used to improve collector performance and system performance or design. In addition, data are being compiled which may be used to define investment requirements for similar installations. The program is also helping to determine community acceptance of solar heated school buildings. Construction was initiated during January 1974 and completed during May 1974. The basic rationale for the program is the necessity of obtaining firm answers in three areas: (1) validation of system performance, (2) determination of overall system costs, and (3) acquisition of data to determine the benefits of such a system.

SciTech Connect

A self-contained passive solar heating system includes first and second heat pipes, each having a refrigerant medium therein, a condenser portion and an evaporator portion, with the condenser portion of the first heat pipe being coupled to the evaporator portion of the second heat pipe for transferring heat thereto when the pressure within the first heat pipe is greater than the pressure within the second heat pipe. The evaporator portion of the first heat pipe is adapted to be exposed to a source of heat and the condenser portion of the second heat pipe contacts a medium to be heated. A temperature control mechanism may be installed as the coupling between the first and second heat pipes for uncoupling the same when the temperature within the first heat pipe falls below a predetermined temperature. Also, a third heat pipe may be provided having a thermostatic portion operatively connected to the condenser portion of the second heat pipe by a piston means so that changes in pressure within the thermostatic portion occasioned by changes in temperature of the medium to be heated will cause movement of the pistons to vary the size of the condensing portion of the second heat pipe to increase or decrease the rate of heat transfer to the medium.

Solar System Tests of f(R) Gravity  

E-Print Network (OSTI)

In this paper, we study the solar system tests of f(R) gravity. When the field f' is light, the post-Newtonian parameter gamma is equal to 1/2. We reobtain this result by focusing on the equations of motion for f(R) gravity in the Jordan frame. The result of gamma=1/2 is a gross violation of the observational value gamma=1. The chameleon mechanism in the Jordan frame is implemented in order to make f(R) gravity pass the solar system tests. The problem of the solar system tests of f(R) gravity is almost identical to the scenario of the false vacuum decay. Consequently, the condition for the validity of a thin-wall approximation in the false vacuum decay can be used as the new condition for the solar system tests. This new condition provides a pictorial interpretation to the solar system tests of f(R) gravity. Numerical simulations of the solar system tests of f(R) gravity are implemented. The combination of analytic and numerical approaches enables us to ascertain whether an f(R) model can pass the solar syste...

Windjammer solar-water-heating system. Final technical report  

DOE Green Energy (OSTI)

The results of the Windjammer Solar-Water-Heating System tests showed that it was not as an efficient system as a comparable conventional system for converting solar energy into heat energy. However, it was determined that the innovative mode used less electric back-up energy for water heating. Reduced fossil fuel energy consumption being the ultimate objective of a solar water heating, the principle employed has been shown to be a workable energy saving concept. The differential mode of temperature control emerged as the more efficient mode of operation for the innovative system and under comparable conditions is projected to be nearly equivalent to the conventional solar system. Although the concept has proven workable, the costs feasible, and the potential for considereable improvements exists, additional research and development is needed to advance the design into its most practical application.

Design and Analysis of Hybrid Solar Lighting and Full-Spectrum Solar Energy Systems  

DOE Green Energy (OSTI)

This paper describes a systems-level design and analysis of a new approach for improving the energy efficiency and affordability of solar energy in buildings, namely, hybrid solar lighting and full-spectrum solar energy systems. By using different portions of the solar spectrum simultaneously for multiple end-use applications in buildings, the proposed system offers unique advantages over other alternatives for using sunlight to displace electricity (conventional topside daylighting and solar technologies). Our preliminary work indicates that hybrid solar lighting, a method of collecting and distributing direct sunlight for lighting purposes, will alleviate many of the problems with passive daylighting systems of today, such as spatial and temporal variability, glare, excess illumination, cost, and energy efficiency. Similarly, our work suggests that the most appropriate use of the visible portion of direct, nondiffuse sunlight from an energy-savings perspective is to displace electric light rather than generate electricity. Early estimates detailed in this paper suggest an anticipated system cost of well under $2.0/Wp and 5-11 {cents}/kWh for displaced and generated electricity in single-story commercial building applications. Based on a number of factors discussed in the paper, including sunlight availability, building use scenarios, time-of-day electric utility rates, cost, and efficacy of the displaced electric lights, the simple payback of this approach in many applications could eventually be well under 5 years.

Preliminary economic assessment or residential passive solar cooling potential in the United States  

DOE Green Energy (OSTI)

In many areas of the continental United States, residential cooling loads are equal to or greater than energy used for residential space heating. Offsetting part of the cooling load could yield considerable dollar savings to the consumer as well as total energy savings. The physical performances of three passive cooling designs are used to estimate the dollar value of first-year fuel savings (excluding heating benefits) and a maximum affordable design cost. The designs include natural ventilation, forced ventilation, and evaoprative cooling concepts. Because economic performance is primarily governed by the level of electricity prices, dollars savings are greatest in regions that show both good physical performance of the cooling design and high electricity prices. Physical and economic performance summaries are presented in mapped form for 220 solar regions within the continental United States.

Solar energy system case study: Telex Communications, Blue Earth, Minnesota  

DOE Green Energy (OSTI)

A study is made of a solar energy system for space heating a 97,000-square-foot office, factory, and warehouse building owned by Telex Communications, Inc. in Blue Earth, Minnesota. The solar system has 11,520 square feet of ground-oriented flat-plate collectors and a 20,000-gallon storage tank inside the building. Freeze protection is by drainback. Solar heated water from the storage tank circulates around the clock throughout the heating season to heating coils in the ducts. The system achieves its design solar fraction, is efficient, and generally reliable, but not cost-effective. Performance data for the solar system was collected by the National Solar Data Network for three heating seasons from 1978 to 1981. Because of a freeze-up of the collector array in December 1978, the solar system was only partially operational in the 1978 to 1979 heating season. The data in this report were collected in the 1979 to 1980 and 1980 to 1981 heating seasons.

Comparative study of different solar cooling systems for buildings in subtropical city  

SciTech Connect

In recent years, more and more attention has been paid on the application potential of solar cooling for buildings. Due to the fact that the efficiency of solar collectors is generally low at the time being, the effectiveness of solar cooling would be closely related to the availability of solar irradiation, climatic conditions and geographical location of a place. In this paper, five types of solar cooling systems were involved in a comparative study for subtropical city, which is commonly featured with long hot and humid summer. The solar cooling systems included the solar electric compression refrigeration, solar mechanical compression refrigeration, solar absorption refrigeration, solar adsorption refrigeration and solar solid desiccant cooling. Component-based simulation models of these systems were developed, and their performances were evaluated throughout a year. The key performance indicators are solar fraction, coefficient of performance, solar thermal gain, and primary energy consumption. In addition, different installation strategies and types of solar collectors were compared for each kind of solar cooling system. Through this comparative study, it was found that solar electric compression refrigeration and solar absorption refrigeration had the highest energy saving potential in the subtropical Hong Kong. The former is to make use of the solar electric gain, while the latter is to adopt the solar thermal gain. These two solar cooling systems would have even better performances through the continual advancement of the solar collectors. It will provide a promising application potential of solar cooling for buildings in the subtropical region. (author)

Tests of general relativity in the solar system  

E-Print Network (OSTI)

Tests of gravity performed in the solar system show a good agreement with general relativity. The latter is however challenged by observations at larger, galactic and cosmic, scales which are presently cured by introducing "dark matter" or "dark energy". A few measurements in the solar system, particularly the so-called "Pioneer anomaly", might also be pointing at a modification of gravity law at ranges of the order of the size of the solar system. The present lecture notes discuss the current status of tests of general relativity in the solar system. They describe metric extensions of general relativity which have the capability to preserve compatibility with existing gravity tests while opening free space for new phenomena. They present arguments for new mission designs and new space technologies as well as for having a new look on data of existing or future experiments.

Performance comparison between air and liquid residential solar heating systems  

SciTech Connect

Comparisons of system performance for the flat plate liquid-heating system in CSU Solar House I, the evacuated-tube collector system in Solar House I, and the flat plate air-heating system in CSU Solar House II are described for selected months of the 1976 and 1977 heating seasons. Only space and domestic water heating data are compared. The flat plate air- and liquid-heating collectors operating with complete heating systems have nearly equal efficiencies when based upon solar flux while the collector fluids are flowing, but approximately 40% more energy is collected during a heating season with the air-heating system because the air system operates over a longer period of the day. On the basis of short-term data, the evacuated tube collector array on Solar House I is about 27% more efficient than the flat plate air-heating collector array on Solar House II based on gross roof area occupied by the collectors and manifolds.

Systems simulation and economic analysis for active solar cooling  

DOE Green Energy (OSTI)

A consistent methodology has been developed by which general solar cooling market capture goals have been translated into specific cost and performance goals for solar cooling systems and subsystems. Preliminary results indicate that realistic cost/performance goals can be established for active solar cooling systems and that, with aggressive development, these goals can be reached by the year 2000. As the technology develops, tax incentives will be required to bridge the gap between the actual costs and the cost goals, so that the scenario of an ever increasing share of market penetration can be maintained over the 1986 to 2000 time period.

As a means of detecting compact ultra dense objects (CUDOs) with nuclear density or greater, and a mass $10^{-10}solar system bodies. We find that a heavy enough CUDO pulverizes, heats and entrains material in a small cylinder around its trajectory through the target body. Because the resulting impact features endure for geologic timescales, data is accumulated over the history of the solar system. Exclusion of all CUDO impact signatures would set a strong limit on their local abundance.

A comparison of eight solar-driven absorption cooling systems in the National Solar Data Network  

Science Conference Proceedings (OSTI)

Large solar driven cooling systems of the absorption chiller type offer opportunities to apply solar energy to the air conditioning of buildings with the attendant savings in conventional energy resources. Many complex design problems are encountered in the attempt to implement this technology. For instance, the range of readily available solar installation operating temperatures is at the low end of the required range for effective operation of the chillers. A study has been made of eight such systems which were operated in a variety of climates during the 1980 cooling season and instrumented within the National Solar Data Network (NSDN). Presented here are summary results of this study. Considerably more detail on the performance of these systems is contained in the reference along with a brief discussion of absorption chillers and their application in solar designs. The performance of the monitored installations was not very good. Only two systems showed energy savings and they were insignificant considering the size of the buildings. Nevertheless valuable lessons were learned from the study. Each system had some desirable design features. Taking these features together, a projected composite system was posited which would have performed fairly well. Suggestions are presented which should lead to more effective designs for this type of renewable energy application.

Reliability analysis of solar photovoltaic system using hourly mean solar radiation data  

Science Conference Proceedings (OSTI)

This paper presents the hourly mean solar radiation and standard deviation as inputs to simulate the solar radiation over a year. Monte Carlo simulation (MCS) technique is applied and MATLAB program is developed for reliability analysis of small isolated power system using solar photovoltaic (SPV). This paper is distributed in two parts. Firstly various solar radiation prediction methods along with hourly mean solar radiation (HMSR) method are compared. The comparison is carried on the basis of predicted electrical power generation with actual power generated by SPV system. Estimation of solar photovoltaic power using HMSR method is close to the actual power generated by SPV system. The deviation in monsoon months is due to the cloud cover. In later part of the paper various reliability indices are obtained by HMSR method using MCS technique. Load model used is IEEE-RTS. Reliability indices, additional load hours (ALH) and additional power (AP) reduces exponentially with increase in load indicates that a SPV source will offset maximum fuel when all of its generated energy is utilized. Fuel saving calculation is also investigated. Case studies are presented for Sagardeep Island in West Bengal state of India. (author)

The Added Economic and Environmental Value of Solar Thermal Systems in Microgrids with CombinedHeat and Power  

Science Conference Proceedings (OSTI)

The addition of solar thermal and heat storage systems can improve the economic, as well as environmental attraction of micro-generation systems, e.g. fuel cells with or without combined heat and power (CHP) and contribute to enhanced CO2 reduction. However, the interactions between solar thermal collection and storage systems and CHP systems can be complex, depending on the tariff structure, load profile, etc. In order to examine the impact of solar thermal and heat storage on CO2 emissions and annual energy costs, a microgrid's distributed energy resources (DER) adoption problem is formulated as a mixed-integer linear program. The objective is minimization of annual energy costs. This paper focuses on analysis of the optimal interaction of solar thermal systems, which can be used for domestic hot water, space heating and/or cooling, and micro-CHP systems in the California service territory of San Diego Gas and Electric (SDG&E). Contrary to typical expectations, our results indicate that despite the high solar radiation in southern California, fossil based CHP units are dominant, even with forecast 2020 technology and costs. A CO2 pricing scheme would be needed to incent installation of combined solar thermal absorption chiller systems, and no heat storage systems are adopted. This research also shows that photovoltaic (PV) arrays are favored by CO2 pricing more than solar thermal adoption.

DOE Green Energy (OSTI)

This Phase II Study of small solar power systems (SSPS) has been structured to determine conditions under which SSPS can be cost-effective sources of electric power in the US in the period 1985 to 2015. An extensive data base, which provides a discrete identification of all utility and industrial electric generating units up to and including 10 MW/sub e/ in rated capacity, has been prepared. This data base defines the market for which comparative evaluations are made of SSPS and alternative fossil-fueled power plants. The market penetration of SSPS is determined and the effect of economic incentives on accelerating the penetration is evaluated. The solar electric power system is evaluated as either a complete replacement for existing conventional electric power systems or as a repowering installation for boilers supplying steam to turbine-driven generators. The cost data used in the market penetration analysis are for a central receiver-type of small solar theral power system. While the market penetration discussed herein is for this type of SSPS, the sensitivity data in the report can be used to determine the market penetration of other types of solar thermal power systems (e.g., point focus distributed receiver) with different system costs.

E-Print Network (OSTI)

Abstract — Sustainable operation of battery powered wireless embedded systems (such as sensor nodes) is a key challenge, and considerable research effort has been devoted to energy optimization of such systems. Environmental energy harvesting, in particular solar based, has emerged as a viable technique to supplement battery supplies. However, designing an efficient solar harvesting system to realize the potential benefits of energy harvesting requires an in-depth understanding of several factors. For example, solar energy supply is highly time varying and may not always be sufficient to power the embedded system. Harvesting components, such as solar panels, and energy storage elements, such as batteries or ultracapacitors, have different voltage-current characteristics, which must be matched to each other as well as the energy requirements of the system to maximize harvesting efficiency. Further, battery nonidealities, such as self-discharge and round trip efficiency, directly affect energy usage and storage decisions. The ability of the system to modulate its power consumption by selectively deactivating its sub-components also impacts the overall power management architecture. This paper describes key issues and tradeoffs which arise in the design of a solar energy harvesting, wireless embedded system and presents the design, implementation, and performance evaluation of Heliomote, our prototype that addresses several of these issues. Experimental results demonstrate that Heliomote, which behaves as a plug-in to the Berkeley/Crossbow motes and autonomously manages energy harvesting and storage, enables near-perpetual, harvesting aware operation of the sensor node.

Energy.gov (U.S. Department of Energy (DOE)) Indexed Site

Thermal Storage System Basics Thermal Storage System Basics Concentrating Solar Power Thermal Storage System Basics August 21, 2013 - 10:33am Addthis One challenge facing the widespread use of solar energy is reduced or curtailed energy production when the sun sets or is blocked by clouds. Thermal energy storage provides a workable solution to this challenge. In a concentrating solar power (CSP) system, the sun's rays are reflected onto a receiver, which creates heat that is used to generate electricity. If the receiver contains oil or molten salt as the heat-transfer medium, then the thermal energy can be stored for later use. This enables CSP systems to be cost-competitive options for providing clean, renewable energy. Several thermal energy storage technologies have been tested and

Discovery of water ice nearly everywhere in the solar system  

DOE Green Energy (OSTI)

During the last decade we have discovered sources of accessible water in some form nearly everywhere in the solar system. Water ice has been found on the planet Mercury; probably on the Earth`s Moon; on Mars; on near Earth objects; on comets whose orbits frequently come close to that of Earth`s orbit; probably on Ceres, the largest inner asteroid; and on comets previously and incorrectly considered to be out of practical reach. The comets also provide massive quantities of hydrocarbons, similar to oil shale. The masses of either water or hydrocarbons are measured in units of cubic kilometers. The water is key to space transportation because it can be used as a rocket propellant directly, and because thermal process alone can be used to convert it and hydrocarbons into hydrogen, the highest performing rocket propellant. This presentation outlines what is currently known about the locations of the water ice, and sketches the requirements and environments of missions to prospect for and assay the water sources.

Market development directory for solar industrial process heat systems  

DOE Green Energy (OSTI)

The purpose of this directory is to provide a basis for market development activities through a location listing of key trade associations, trade periodicals, and key firms for three target groups. Potential industrial users and potential IPH system designers were identified as the prime targets for market development activities. The bulk of the directory is a listing of these two groups. The third group, solar IPH equipment manufacturers, was included to provide an information source for potential industrial users and potential IPH system designers. Trade associates and their publications are listed for selected four-digit Standard Industrial Code (SIC) industries. Since industries requiring relatively lower temperature process heat probably will comprise most of the near-term market for solar IPH systems, the 80 SIC's included in this chapter have process temperature requirements less than 350/sup 0/F. Some key statistics and a location list of the largest plants (according to number of employees) in each state are included for 15 of the 80 SIC's. Architectural/engineering and consulting firms are listed which are known to have solar experience. Professional associated and periodicals to which information on solar IPH sytstems may be directed also are included. Solar equipment manufacturers and their associations are listed. The listing is based on the SERI Solar Energy Information Data Base (SEIDB).

Identifying Challenging Operating Hours for Solar Intergration in the NV Energy System  

Science Conference Proceedings (OSTI)

Abstract-- In this paper, the ability of the Nevada (NV) Energy generation fleet to meet its system balancing requirements under different solar energy penetration scenarios is studied. System balancing requirements include capacity, ramp rate, and ramp duration requirements for load following and regulation. If, during some operating hours, system capability is insufficient to meet these requirements, there is certain probability that the balancing authority’s control and reliability performance can be compromised. These operating hours are considered as “challenging” hours. Five different solar energy integration scenarios have been studied. Simulations have shown that the NV Energy system will be potentially able to accommodate up to 942 MW of solar photovoltaic (PV) generation. However, the existing generation scheduling procedure should be adjusted to make it happen. Fast-responsive peaker units need to be used more frequently to meet the increasing ramping requirements. Thus, the NV Energy system operational cost can increase. Index Terms—Solar Generation, Renewables Integration, Balancing Process, Load Following, Regulation.

Correlation Between Geographically Dispersed Concentrating Solar Power and Demand in the United States  

Science Conference Proceedings (OSTI)

Correlations between the electricity generated by concentrating solar thermal power (CSP) plants, as well as cross-correlations between CSP, wind power and electricity demand, have significant impacts on decisions for how much and where to build utility-scale CSP capacity, the optimal amount of thermal storage in the CSP plants, reserve capacity needed to back-up the system, as well as the expected levels of curtailed renewable power. Accurately estimating these correlations is vital to performing detailed analyses of high renewable penetration scenarios. This study quantifies the degree of correlation between geographically dispersed CSP, as well as the correlation between CSP and wind power, and CSP and electricity demand in 356 discrete regions in the contiguous US. Correlations are calculated using hourly data on an annual basis. Maps of the correlations will be presented to illustrate the degree of correlation between solar power and the demand it is serving, as well as the synergies between the negatively-correlated wind power and solar power serving the same region.

Actual versus design performance of solar systems in the National Solar Data Network  

Science Conference Proceedings (OSTI)

This report relates field measured performance to the designer predicted performance. The field measured data was collected by the National Solar Data Network (NSDN) over a period of six years. Data from 25 solar systems was selected from a data pool of some 170 solar systems. The scope of the project extends beyond merely presenting comparisons of data. There is an attempt to provide answers which will move the solar industry forward. As a result of some industry and research workshops, several concerns arose which can be partially allayed by careful study of the NSDN data. These are: What types of failures occurred and why. How good was the design versus actual performance. Why was predicted performance not achieved in the field. Which components should be integrated with a system type for good performance. Since the designs span several years and since design philosophies are quite variable, the measured results were also compared to f-Chart 5.1 results. This comparison is a type of normalization in that all systems are modeled with the same process. An added benefit of this normalization is a further validation of the f-Chart model on a fairly large scale. The systems were modeled using equipment design parameters, measured loads, and f-Chart weather data from nearby cities.

Hybrid photovoltaic/thermal (PV/T) solar systems simulation with Simulink/Matlab  

Science Conference Proceedings (OSTI)

The purpose of this work consists in thermodynamic modeling of hybrid photovoltaic-thermal (PV/T) solar systems, pursuing a modular strategy approach provided by Simulink/Matlab. PV/T solar systems are a recently emerging solar technology that allows for the simultaneous conversion of solar energy into both electricity and heat. This type of technology present some interesting advantages over the conventional ''side-by-side'' thermal and PV solar systems, such as higher combined electrical/thermal energy outputs per unit area, and a more uniform and aesthetical pleasant roof area. Despite the fact that early research on PV/T systems can be traced back to the seventies, only recently it has gained a renewed impetus. In this work, parametric studies and annual transient simulations of PV/T systems are undertaken in Simulink/Matlab. The obtained results show an average annual solar fraction of 67%, and a global overall efficiency of 24% (i.e. 15% thermal and 9% electrical), for a typical four-person single-family residence in Lisbon, with p-Si cells, and a collector area of 6 m{sup 2}. A sensitivity analysis performed on the PV/T collector suggests that the most important variable that should be addressed to improve thermal performance is the photovoltaic (PV) module emittance. Based on those results, some additional improvements are proposed, such as the use of vacuum, or a noble gas at low-pressure, to allow for the removal of PV cells encapsulation without air oxidation and degradation, and thus reducing the PV module emittance. Preliminary results show that this option allows for an 8% increase on optical thermal efficiency, and a substantial reduction of thermal losses, suggesting the possibility of working at higher fluid temperatures. The higher working temperatures negative effect in electrical efficiency was negligible, due to compensation by improved optical properties. The simulation results are compared with experimental data obtained from other authors and perform reasonably well. The Simulink modeling platform has been mainly used worldwide on simulation of control systems, digital signal processing and electric circuits, but there are very few examples of application to solar energy systems modeling. This work uses the modular environment of Simulink/Matlab to model individual PV/T system components, and to assemble the entire installation layout. The results show that the modular approach strategy provided by Matlab/Simulink environment is applicable to solar systems modeling, providing good code scalability, faster developing time, and simpler integration with external computational tools, when compared with traditional imperative-oriented programming languages.

SciTech Connect

The three volumes of this report cover three distinct areas of solar energy research: solar thermoelectrics, solar-wind hybrid systems, and synthetic fuels derived with solar thermal energy. Volume III deals with the conversion of synthetic fuels with solar thermal heat. The method is a hybrid combination of solar energy with either coal or biomass. A preliminary assessment of this technology is made by calculating the cost of fuel produced as a function of the cost of coal and biomass. It is shown that within the projected ranges of coal, biomass, and solar thermal costs, there are conditions when solar synthetic fuels with solar thermal heat will become cost-competitive.

DOE Green Energy (OSTI)

In keeping with the national energy policy goal of fostering an adequate supply of energy at a reasonable cost, the United States Department of Energy (DOE) supports a variety of programs to promote a balanced and mixed energy resource system. The mission of the DOE Solar Buildings Research and Development Program is to support this goal, by providing for the development of solar technology alternatives for the buildings sector. It is the goal of the Program to establish a proven technology base to allow industry to develop solar products and designs for buildings that are economically competitive and can contribute significantly to building energy supplies nationally. Toward this end, the program sponsors research activities related to increasing the efficiency, reducing the cost, and improving the long-term durability of passive and active solar systems for building water and space heating, cooling, and daylighting applications. These activities are conducted in four major areas: Advanced Passive Solar Materials Research, Collector Technology Research, Cooling Systems Research, and Systems Analysis and Applications Research.

Solar Energy system performance evaluation: El Toro, California, March 1981-November 1981  

DOE Green Energy (OSTI)

The El Toro Library is a public library facility in California with an active solar energy system designed to supply 97% of the heating load and 60% of the cooling load. The system is equipped with 1427 square feet of evacuated tube collectors, a 1500-gallon steel storage tank, and an auxiliary natural-gas-fired heating unit. During the period from March 1981 through November 1981 the system supplied only 16% of the space cooling load, far short of the 60% design value. Problems are reported related to control of a valve and of collection, low absorption chiller coefficient of performance during part of the period, and small collector area. Performance data are reported for the system, including solar savings ratio, conventional fuel savings, system performance factor, system coefficient of performance, solar energy utilization, and system operation. Subsystem performance data are also given for the collector, storage, and space cooling subsystems and absorption chiller. The system is briefly described along with performance evaluation techniques and sensors, and typical data are presented for one month. Some weather data are also included. (LEW)

Huge Quantum Gravity Effects in the Solar System  

E-Print Network (OSTI)

Normally one thinks of the motion of the planets around the Sun as a highly classical phenomenon, so that one can neglect quantum gravity in the Solar System. However, classical chaos in the planetary motion amplifies quantum uncertainties so that they become very large, giving huge quantum gravity effects. For example, evidence suggests that Uranus may eventually be ejected from the Solar System, but quantum uncertainties would make the direction at which it leaves almost entirely uncertain, and the time of its exit uncertain by about a billion billion years. For a time a billion billion years from now, there are huge quantum uncertainties whether Uranus will be within the Solar System, within the Galaxy, or even within causal contact of the Galaxy.

High performance solar desiccant cooling system: performance evaluations and research recommendations  

DOE Green Energy (OSTI)

This report presents an assessment of the current status of solar desiccant cooling and makes recommendations for continued research to develop high performance systems competitive with conventional cooling systems. Solid desiccant, liquid desiccant, and hybrid systems combining desiccant dehumidifiers with vapor compressor units are considered. Currently, all desiccant systems fall somewhat short of being competitive with conventional systems. Hybrid systems appear to have the greatest potential in the short term. Solid systems are close to meeting performance goals. Development of high performance solid desiccant dehumidifiers based on parallel passage designs should be pursued. Liquid system collector/generators and efficient absorbers should receive attention. Model development is also indicated. Continued development by hybrid systems is directly tied to the above work.

Systems analysis techniques for annual cycle thermal energy storage solar systems  

DOE Green Energy (OSTI)

Community-scale annual cycle thermal energy storage (ACTES) solar systems are promising options for building heat and cooling. A variety of approaches are feasible in modeling ACTES solar systems. The key parameter in such efforts, average collector efficiency, is first examined, followed by several approaches for simple and effective modeling. Methods are also examined for modeling building loads for structures based on both conventional and passive architectural designs. Two simulation models for sizing solar heating systems with annual storage are presented next. Validation is presented by comparison with the results of a study of seasonal storage systems based on SOLANSIM, an hour-by-hour simulation. These models are presently being used to examine the economic trade-off between collector field area and storage capacity.

Summary of three regional assessment studies of solar electric generation opportunities in the Southwest, Southeast, and Northeast United States  

DOE Green Energy (OSTI)

Market opportunities for solar generation of electricity for utility and for residential/commercial/industrial applications in the Northeast, Southeast, and Southwest regions of the United States were evaluated in three studies (JBF 1979, Stone and Webster 1979a, 1979b) and are summarized. The evaluations were based on both economic analyses and user perception of what they would require to select or approve the use of solar electric generation for themselves or for their employers. Over 30 utilities and several industrial and commercial firms and homeowners were involved. Solar electric technologies considered included biomass, hybrid retrofit, OTEC, photovoltaic, solar thermal, and wind. The studies projected that solar electric technologies could account for several percent of the forecast generation in year 2000 in the Southeast and Southwest regions,and up to 10 to 20% in the Northeast region. No single solar electric technology or application (for utility or industrial/commercial/residential use) arrived earlier at economic breakeven than other technologies in the Southeast region, but wind generation for both utility and industrial applications predominated in the Northeast region. The Southwest region, in which only utility applications were considered, showed wind energy and retrofit hybrid (a solar adjunct to an existing fossil-fueled plant) to be the most likely early applications.

Analysis of a direct radiation solar dehumidification system  

DOE Green Energy (OSTI)

SERI researchers investigated a desiccant dehumidifier that is regenerated by direct absorption of solar radiation using a simplified numerical model (DESSIM) of the adsorption and desorption processes. This paper presents estimates of the performance of a solar-fired air conditioning system (ventilation cycle) containing the dehumidifier/collector. The researchers also considered the effects of dehumidifier NTUs, heat exchanger performance, and insolation levels. The direct radiation system can operate effectively at low insolation levels and thus may have some advantages in some geographic areas.

Do Solar system tests permit higher dimensional general relativity?  

E-Print Network (OSTI)

We perform a survey whether higher dimensional Schwarzschild space-time is compatible with some of the solar system phenomena. As a test we examine five well known solar system effects, viz., (1) Perihelion shift, (2) Bending of light, (3) Gravitational redshift, (4) Gravitational time delay and (5) Motion of test particle in the framework of general relativity with higher dimensions. It is shown that the results related to all these physical phenomena are mostly incompatible with the higher dimensional version of general relativity except that of Motion of test particle. We compare all these results with the available data in the literature.

End-use matching of solar energy systems  

SciTech Connect

The choice among available energy sources for a given task requires technical and economic tradeoffs on the part of the individual investor. From the national perspective, however, the effectiveness with which available energy sources are utilized may well become an overriding consideration. End-use matching is a procedure for introducing solar energy into the national energy infrastructure. The result of end-use matching is an identification of the most cost-effective combination of process energy needs, solar collector technology, geographic location, and economics by matching currently available solar system hardware with particular industrial processes and their locations. End-use matching is not intended to be a design tool for a specific plant, but rather a planning tool for determining where and for what general applications solar systems appear economically viable in the near- to immediate-term. This paper discusses the end-use matching methodology and illustrates first and second law thermodynamics analyses applied to a solar system producing process steam.

Performance improvement of a solar heating system utilizing off-peak electric auxiliary. Semi-annual progress report, June 18, 1979-December 31, 1979  

SciTech Connect

During the period 18 June 1979 through December 1979, a solar assisted heat pump system was designed, installed and operated in the University of Toledo Experimental Solar House. The heat pump system is capable of operating in a wide range of temperatures which is needed in a solar house utilizing off-peak storage from the electric utility. The complete system consists of 584.1 square feet of Libbey-Owens-Ford's flat plate solar collectors, a 5 horsepower compressor (Victaulic Corp.), an evaporator (Dunham-Bush), a condensor (Dunham-Bush), thermal storage units, and associated equipment. During the installation and initial operation of the system, numerous aspects of the feasibility of this system design have been evaluated. Many of these aspects point to the potentially improved operating performance of a solar heating system utilizing off-peak storage from the electric utility.

Radioisotope electric propulsion of sciencecraft to the outer solar system and near-interstellar space  

Science Conference Proceedings (OSTI)

Recent results are presented in the study of radioisotope electric propulsion as a near-term technology for sending small robotic sciencecraft to the outer Solar System and near-interstellar space. Radioisotope electric propulsion (REP) systems are low-thrust, ion propulsion units based on radioisotope electric generators and ion thrusters. Powerplant specific masses are expected to be in the range of 100 to 200 kg/kW of thrust power. Planetary rendezvous missions to Pluto, fast missions to the heliopause (100 AU) with the capability to decelerate an orbiter for an extended science program and prestellar missions to the first gravitational lens focus of the Sun (550 AU) are investigated.

P50/P90 Analysis for Solar Energy Systems Using the System Advisor Model: Preprint  

DOE Green Energy (OSTI)

To secure competitive financing for a solar energy generation project, the economic risk associated with interannual solar resource variability must be quantified. One way to quantify this risk is to calculate exceedance probabilities representing the amount of energy expected to be produced by a plant. Many years of solar radiation and metereological data are required to determine these values, often called P50 or P90 values for the level of certainty they represent. This paper describes the two methods implemented in the National Renewable Energy Laboratory's System Advisor Model (SAM) to calculate P50 and P90 exceedance probabilities for solar energy projects. The methodology and supporting data sets are applicable to photovoltaic, solar water heating, and concentrating solar power (CSP) systems.

Reliability assessment of active residential solar energy systems, Phase I  

SciTech Connect

Experiences with active solar energy systems in the last few years have, in many cases, been less than encouraging. A quantification of the problem areas discovered in a sampling of the active residential solar energy systems in the state of Colorado is presented. While many problems were found, the potential for easy solution of the problems by design or installation refinement is great. Reported is a summary of the findings of the mechanical inspections of twelve systems during the 1978-79 winter. Only one system operated at its expected mechanical, thermal and economic performance level. Four other systems performed well mechanically, but only one of these had thermal performance meeting design expectations. The remaining seven systems did not work well mechanically or thermally. One significantly raised the utility bill of the residence on which it was installed. Poor system design was found to be the major cause of low performance. Also, installation quality was low and installation errors were frequent. Qualified solar system service was virtually unavailable. Nearly all the problems found were solvable using present technology. The greatest immediate need is for training of designers, installers and service people and support of off-market development of total systems.

Mission analysis of photovoltaic solar energy systems. Final report. Volume I. Summary  

SciTech Connect

A summary report of a study program whose principal objective was to develop methods for the technical and economic evaluation of potential missions (applications) for photovoltaic solar energy conversion in the southwestern United States in the 1980 to 2000 period is presented. A secondary objective was to apply the methodology, when developed, to the evaluation of a number of illustrative examples of candidate missions in order to obtain at least a preliminary indication of the competitive position of the photovoltaic technology in the future energy economy of the Southwest. Because of their large potential significance, most of the effort in the study was devoted to two main classes of missions: on-site applications (in which the photovoltaic system serves an electric load point that is colocated with the system) and central station power plant applications. A smaller amount of attention was given to the electrolytic production of hydrogen with electric power generated by the photovoltaic conversion of solar energy. (WHK)

DOE Green Energy (OSTI)

Environmental control of a building is considered with respect to: the structural shell, HVAC distribution system, HVAC energy conversion equipment, HVAC control systems, and human factors. Modeling and computer simulation of solar HVAC systems is briefly discussed along with experimental testing by two methods--experimental operation of a solar HVAC system with a simulated collector, and experimental operation of a complete system under real weather and load conditions. Prior experimental test projects are discussed briefly and tabulated. Finally, a test program is recommended that consists of: development of a complete computer simulation model, development of control strategies to be tested, development of computer simulation sub-routines for control strategies, testing of control strategies by computer simulation, experimental testing, and data analysis. Each of these tasks is described individually. (LEW)
