Global warming description using Daisyworld model with greenhouse gases  

Science Journals Connector (OSTI)

Abstract Daisyworld is an archetypal model of the earth that is able to describe the global regulation that can emerge from the interaction between life and environment. This article proposes a model based on the original Daisyworld considering greenhouse gases emission and absorption, allowing the description of the global warming phenomenon. Global and local analyses are discussed evaluating the influence of greenhouse gases in the planet dynamics. Numerical simulations are carried out showing the general qualitative behavior of the Daisyworld for different scenarios that includes solar luminosity variations and greenhouse gases effect. Nonlinear dynamics perspective is of concern discussing a way that helps the comprehension of the global warming phenomenon.

The Role of Subtropical Irreversible PV Mixing in the Zonal Mean Circulation Response to Global Warming-like Thermal Forcing  

SciTech Connect (OSTI)

The atmospheric circulation response to the global warming-like tropical upper tropospheric heating is revisited using a dry atmospheric general circulation model (AGCM) in light of a new diagnostics based on the concept of finite-amplitude wave activity (FAWA) on equivalent latitude. For a given tropical heating profile, the linear Wentzel-Kramers-Brillouin (WKB) wave refraction analysis sometimes gives a very different and even opposite prediction of the eddy momentum flux response to that of the actual full model simulation, exposing the limitation of the traditional linear approach in understanding the full dynamics of the atmospheric response under global warming. The implementation of the FAWA diagnostics reveals that in response to the upper tropospheric heating, effective diffusivity, a measure of the mixing efficiency, increases and advances upward and poleward in the subtropics and the resultant enhancement and the poleward encroachment of eddy potential vorticity mixing leads to a poleward displaced potential vorticity (PV) gradient peak in the upper troposphere. The anomalous eddy PV flux, in balance with the PV dissipation, gives rise to a poleward shift in the eddy-driven jet and eddy-driven mean meridional circulation. Sensitivity experiments show that these irreversible dissipation processes in the upper troposphere are robust, regardless of the width of the tropical heating.

Global phenomenological descriptions of nuclear odd-even mass staggering  

E-Print Network [OSTI]

We examine the general nature of nuclear odd-even mass differences by employing neutron and proton mass relations that emphasize these effects. The most recent mass tables are used. The possibility of a neutron excess dependence of the staggering is examined in detail in separate regions defined by the main nuclear shells, and a clear change in this dependency is found at $Z=50$ for both neutrons and protons. A further separation into odd and even neutron (proton) number produces very accurate local descriptions of the mass differences for each type of nucleons. These odd-even effects are combined into a global phenomenological expression, ready to use in a binding energy formula. The results deviate from previous parametrizations, and in particular found to be significantly superior to a recent two term, $A^{-1}$ dependence.

Light beams with general direction and polarization: global description and geometric phase  

E-Print Network [OSTI]

We construct the manifold describing the family of plane monochromatic light waves with all directions, polarizations, phases and intensities. A smooth description of polarization, valid over the entire sphere S^2 of directions, is given through the construction of an orthogonal basis pair of complex polarization vectors for each direction; any light beam is then uniquely and smoothly specified by giving its direction and two complex amplitudes. This implies that the space of all light beams is the six dimensional manifold S^2 X C^2, the Cartesian product of a sphere and a two dimensional complex vector space. A Hopf map (i.e mapping the two complex amplitudes to the Stokes parameters) then leads to the four dimensional manifold S^2 X S^2 which describes beams with all directions and polarization states. This product of two spheres can be viewed as an ordered pair of two points on a single sphere, in contrast to earlier work in which the same system was represented using Majorana's mapping of the states of a spin one quantum system to an unordered pair of points on a sphere. This is a different manifold, CP^2, two dimensional complex projective space, which does not faithfully represent the full space of all directions and polarizations. Following the now-standard framework, we exhibit the fibre bundle whose total space is the set of all light beams of non-zero intensity, and base space S^2 X S^2. We give the U(1) connection which determines the geometric phase as the line integral of a one-form along a closed curve in the total space. Bases are classified as globally smooth, global but singular, and local, with the last type of basis being defined only when the curve traversed by the system is given. Existing as well as new formulae for the geometric phase are presented in this overall framework.

At the same time, the U.S. market share has slipped from 30% to 7% (30% CAGR) while China/Taiwan has grown from <2% to 54% (115% CAGR) to become the leader in global production. NREL's manufacturing cost analysis has focused on understanding the regional competitiveness of solar PV manufacturing specifically: What factors have led to China's dramatic growth in PV? Is it sustainable? Can the US compete? NREL's manufacturing cost analysis studies show that: U.S. incentives to strengthen access to capital for investment in innovative solar technologies could offset China's current advantage U.S. incentives are dwarfed by the scale of Chinese incentives

Atmospheric conditions at the site of a cosmic ray observatory must be known for reconstructing observed extensive air showers. The Global Data Assimilation System (GDAS) is a global atmospheric model predicated on meteorological measurements and numerical weather predictions. GDAS provides altitude-dependent profiles of the main state variables of the atmosphere like temperature, pressure, and humidity. The original data and their application to the air shower reconstruction of the Pierre Auger Observatory are described. By comparisons with radiosonde and weather station measurements obtained on-site in Malargue and averaged monthly models, the utility of the GDAS data is shown.

3-Port Single-Stage PV & Battery Converter Improves Efficiency and Cost in Combined PV/Battery Systems  

SciTech Connect (OSTI)

Due to impressive cost reductions in recent years, photovoltaic (PV) generation is now able to produce electricity at highly competitive prices, but PVs inherent intermittency reduces the potential value of this energy. The integration of battery storage with PV will be transformational by increasing the value of solar. Utility scale systems will benefit by firming intermittency including PV ramp smoothing, grid support and load shifting, allowing PV to compete directly with conventional generation. For distributed grid-tied PV adding storage will reduce peak demand utility charges, as well as providing backup power during power grid failures. The largest long term impact of combined PV and battery systems may be for delivering reliable off-grid power to the billions of individuals globally without access to conventional power grids, or for billions more that suffer from daily power outages. PV module costs no longer dominate installed PV system costs. Balance-of-System (BOS) costs including the PV inverter and installation now contribute the majority of installed system costs. Battery costs are also dropping faster than installation and battery power converter systems. In each of these separate systems power converters have become a bottleneck for efficiency, cost and reliability. These bottlenecks are compounded in hybrid power conversion systems that combine separate PV and battery converters. Hybrid power conversion systems have required multiple power converters hardware units and multiple power conversion steps adding to efficiency losses, product and installation costs, and reliability issues. Ideal Power Converters has developed and patented a completely new theory of operation for electronic power converters using its indirect EnergyPacket Switching topology. It has established successful power converter products for both PV and battery systems, and its 3-Port Hybrid Converter is the first product to exploit the topologys capability for the industrys first single-stage multi-port hybrid power converter. This unique low cost approach eliminates the hybrid power conversion bottlenecks when integrating batteries into PV systems. As result this product will significantly accelerate market adoption of these systems.

PSCAD Modules Representing PV Generator  

SciTech Connect (OSTI)

Photovoltaic power plants (PVPs) have been growing in size, and the installation time is very short. With the cost of photovoltaic (PV) panels dropping in recent years, it can be predicted that in the next 10 years the contribution of PVPs to the total number of renewable energy power plants will grow significantly. In this project, the National Renewable Energy Laboratory (NREL) developed a dynamic modeling of the modules to be used as building blocks to develop simulation models of single PV arrays, expanded to include Maximum Power Point Tracker (MPPT), expanded to include PV inverter, or expanded to cover an entire PVP. The focus of the investigation and complexity of the simulation determines the components that must be included in the simulation. The development of the PV inverter was covered in detail, including the control diagrams. Both the current-regulated voltage source inverter and the current-regulated current source inverter were developed in PSCAD. Various operations of the PV inverters were simulated under normal and abnormal conditions. Symmetrical and unsymmetrical faults were simulated, presented, and discussed. Both the three-phase analysis and the symmetrical component analysis were included to clarify the understanding of unsymmetrical faults. The dynamic model validation was based on the testing data provided by SCE. Testing was conducted at SCE with the focus on the grid interface behavior of the PV inverter under different faults and disturbances. The dynamic model validation covers both the symmetrical and unsymmetrical faults.

Do feed-in tariffs drive PV cost or viceversa?  

Science Journals Connector (OSTI)

Abstract A survey of the PV market in Italy was done studying a number of installations of different sizes whose economic data were known and assessed. The Italian market has experienced a boom in the PV market after the first mechanism of feed-in tariffs was promoted in 2005. The variations of the tariff structure in the following years have caused significant changes in the market structure in terms of average size and technical characteristics of installed plants. However, an Italian PV industry was not stimulated by the incentives and only companies involved in installation and maintenance were created. At the same time, the cost of the PV plants components, design and commissioning have followed quite a particular trend, which is more determined by the tariffs than by the market development and structure. It is quite clear that the costs of PV plants component are not driven by the amount of installations but by the tariffs, with a trend that follows the decreases in the incentives and not the global installed power. It is therefore very important to study the right tariff mechanisms and benefits to avoid financial disturbances on the market and to promote a real competitive market instead of a simple financial operation under a fake faade of green economy.

Comparison of Pyranometers vs. PV Reference Cells for Evaluation of PV Array Performance  

SciTech Connect (OSTI)

As the photovoltaics (PV) industry has grown, the need for accurately monitoring the solar resource of PV power plants has increased. Historically, the PV industry has relied on thermopile pyranometers for irradiance measurements, and a large body of historical irradiance data taken with pyranometers exists. However, interest in PV reference devices is increasing. In this paper, we discuss why PV reference devices are better suited for PV applications, and estimate the typical uncertainties in irradiance measurements made with both pyranometers and PV reference devices. We assert that the quantity of interest in monitoring a PV power plant is the equivalent irradiance under the IEC 60904-3 reference solar spectrum that would produce the same electrical response in the PV array as the incident solar radiation. For PV-plant monitoring applications, we find the uncertainties in irradiance measurements of this type to be on the order of +/-5% for thermopile pyranometers and +/-2.4% for PV reference devices.

Life-cycle assessment of multi-crystalline photovoltaic (PV) systems in China  

Science Journals Connector (OSTI)

Abstract This study performs a life-cycle assessment for a photovoltaic (PV) system with multi-crystalline silicon (multi-Si) modules in China. It considers the primary energy demand, energy payback time (EPBT), and environmental impacts, such as global warming potential and eutrophication, over the entire life cycle of the PV system, including the upstream process, ranging from silica extraction to the multi-Si purification, the midstream process, involving crystalline silicon ingot growth and wafering; and the downstream process, consisting of cell and module fabrication. The data were collected with recommendations provided by the ISO norms and acquired from typical PV companies in China. The results show that the most critical phase of life cycle of Chinese PV system was the transformation of metallic silicon into solar silicon, which was characterized by high electricity consumption, representing most of the environmental impact. The other electricity generation systems were compared to PV. Considering that Chinese electricity is mainly produced by coal-fired power plants, the installation of multi-Si PV systems is recommended over exporting them from China. Furthermore, being higher solar radiation areas, areas in western China, such as the Tibet Autonomous Region, northeastern Qinghai, and the western borders of Gansu, are best suited for the installation of the PV systems even if the long distance of transportation. Finally, recommendations were provided with respect to the sustainable development of the Chinese PV industry and environmental protection.

A hybrid life-cycle inventory for multi-crystalline silicon PV module manufacturing in China  

Science Journals Connector (OSTI)

China is the world's largest manufacturer of multi-crystalline silicon photovoltaic (mc-Si PV) modules, which is a key enabling technology in the global transition to renewable electric power systems. This study presents a hybrid life-cycle inventory (LCI) of Chinese mc-Si PV modules, which fills a critical knowledge gap on the environmental implications of mc-Si PV module manufacturing in China. The hybrid LCI approach combines process-based LCI data for module and poly-silicon manufacturing plants with a 2007 China IO-LCI model for production of raw material and fuel inputs to estimate 'cradle to gate' primary energy use, water consumption, and major air pollutant emissions (carbon dioxide, methane, sulfur dioxide, nitrous oxide, and nitrogen oxides). Results suggest that mc-Si PV modules from China may come with higher environmental burdens that one might estimate if one were using LCI results for mc-Si PV modules manufactured elsewhere. These higher burdens can be reasonably explained by the efficiency differences in China's poly-silicon manufacturing processes, the country's dependence on highly polluting coal-fired electricity, and the expanded system boundaries associated with the hybrid LCI modeling framework. The results should be useful for establishing more conservative ranges on the potential 'cradle to gate' impacts of mc-Si PV module manufacturing for more robust LCAs of PV deployment scenarios.

Potential residential PV development in Chile: The effect of Net Metering and Net Billing schemes for grid-connected PV systems  

Science Journals Connector (OSTI)

Abstract In recent years the global photovoltaic (PV) market has expanded rapidly due to a sharp decline in PV prices and increased attention to the importance of sustainable energy. Northern Chile has one of the highest irradiance levels in the world as well as one the highest electricity rates in Latin America. Because of these conditions, Chile is one of very few countries where several PV projects are being developed without government subsidies and consequently, the PV industry is experiencing rapid growth. This paper reviews the opportunity to take advantage of these market conditions within the residential sector, modeling PV arrays across 10 cities in Chile. A detailed modeling of PV systems is performed to achieve an accurate analysis of energy production and electricity cost, using local resource data, optimal array orientation and inclination, and production losses. A review of how Net Metering and Net Billing affect the value of the PV production is applied and a comparison using levelized cost of electricity (LCOE) is conducted. Net Metering is found to be a better policy choice to promote PV systems than Net Billing because energy injected into the electrical network is paid at the complete retail rate. However, in developed countries this kind of policy is unlikely to be supported because of it?s economic unfeasibility. Under a Net Billing scheme a consumer will see an advantage when energy is recorded over longer time intervals and when installing a system with smaller capacity relative to household electricity consumption. This prevents excess generation from being injected into the network which would be bought by the utility at lower prices than the retail rate. Payback periods are found to be low, between 6 years in northern areas with high retail rates and 13 years in other areas with lower radiation and retail rates.

PV output smoothing with energy storage.  

SciTech Connect (OSTI)

This report describes an algorithm, implemented in Matlab/Simulink, designed to reduce the variability of photovoltaic (PV) power output by using a battery. The purpose of the battery is to add power to the PV output (or subtract) to smooth out the high frequency components of the PV power that that occur during periods with transient cloud shadows on the PV array. The control system is challenged with the task of reducing short-term PV output variability while avoiding overworking the battery both in terms of capacity and ramp capability. The algorithm proposed by Sandia is purposely very simple to facilitate implementation in a real-time controller. The control structure has two additional inputs to which the battery can respond. For example, the battery could respond to PV variability, load variability or area control error (ACE) or a combination of the three.

PV array simulator development and validation.  

SciTech Connect (OSTI)

The ability to harvest all available energy from a photovoltaic (PV) array is essential if new system developments are to meet levelized cost of energy targets and achieve grid parity with conventional centralized utility power. Therefore, exercising maximum power point tracking (MPPT) algorithms, dynamic irradiance condition operation and startup and shutdown routines and evaluating inverter performance with various PV module fill-factor characteristics must be performed with a repeatable, reliable PV source. Sandia National Laboratories is collaborating with Ametek Programmable Power to develop and demonstrate a multi-port TerraSAS PV array simulator. The simulator will replicate challenging PV module profiles, enabling the evaluation of inverter performance through analyses of the parameters listed above. Energy harvest algorithms have traditionally implemented methods that successfully utilize available energy. However, the quantification of energy capture has always been difficult to conduct, specifically when characterizing the inverter performance under non-reproducible dynamic irradiance conditions. Theoretical models of the MPPT algorithms can simulate capture effectiveness, but full validation requires a DC source with representative field effects. The DC source being developed by Ametek and validated by Sandia is a fully integrated system that can simulate an IV curve from the Solar Advisor Model (SAM) module data base. The PV simulator allows the user to change the fill factor by programming the maximum power point voltage and current parameters and the open circuit voltage and short circuit current. The integrated PV simulator can incorporate captured irradiance and module temperature data files for playback, and scripted profiles can be generated to validate new emerging hardware embedded with existing and evolving MPPT algorithms. Since the simulator has multiple independent outputs, it also has the flexibility to evaluate an inverter with multiple MPPT DC inputs. The flexibility of the PV simulator enables the validation of the inverter's capability to handle vastly different array configurations.

Updating Technical Screens for PV Interconnection: Preprint  

SciTech Connect (OSTI)

Solar photovoltaics (PV) is the dominant type of distributed generation (DG) technology interconnected to electric distribution systems in the United States, and deployment of PV systems continues to increase rapidly. Considering the rapid growth and widespread deployment of PV systems in United States electric distribution grids, it is important that interconnection procedures be as streamlined as possible to avoid unnecessary interconnection studies, costs, and delays. Because many PV interconnection applications involve high penetration scenarios, the process needs to allow for a sufficiently rigorous technical evaluation to identify and address possible system impacts. Existing interconnection procedures are designed to balance the need for efficiency and technical rigor for all DG. However, there is an implicit expectation that those procedures will be updated over time in order to remain relevant with respect to evolving standards, technology, and practical experience. Modifications to interconnection screens and procedures must focus on maintaining or improving safety and reliability, as well as accurately allocating costs and improving expediency of the interconnection process. This paper evaluates the origins and usefulness of the capacity penetration screen, offers potential short-term solutions which could effectively allow fast-track interconnection to many PV system applications, and considers longer-term solutions for increasing PV deployment levels in a safe and reliable manner while reducing or eliminating the emphasis on the penetration screen.

Standards for PV Modules and Components -- Recent Developments and Challenges: Preprint  

SciTech Connect (OSTI)

International standards play an important role in the Photovoltaic industry. Since PV is such a global industry it is critical that PV products be measured and qualified the same way everywhere in the world. IEC TC82 has developed and published a number of module and component measurement and qualification standards. These are continually being updated to take advantage of new techniques and equipment as well as better understanding of test requirements. Standards presently being updated include the third edition of IEC 61215, Crystalline Silicon Qualification and the second edition of IEC 61730, PV Module Safety Requirements. New standards under development include qualification of junction boxes, connectors, PV cables, and module integrated electronics as well as for testing the packaging used during transport of modules. After many years of effort, a draft standard on Module Energy Rating should be circulated for review soon. New activities have been undertaken to develop standards for the materials within a module and to develop tests that evaluate modules for wear-out in the field (International PV Module QA Task Force). This paper will discuss these efforts and indicate how the audience can participate in development of international standards.

Evaluation of Encapsulant Materials for PV Applications  

SciTech Connect (OSTI)

Encapsulant materials used in PV modules serve multiple purposes. They physically hold components in place, provide electrical insulation, optically couple superstrate materials (e.g., glass) to PV cells, protect components from mechanical stress by mechanically de-coupling components via strain relief, and protect materials from corrosion. To do this, encapsulants must adhere well to all surfaces, remain compliant, and transmit light after exposure to temperature, humidity, and UV radiation histories. Encapsulant materials by themselves do not completely prevent water vapour ingress [1-3], but if they are well adhered, they will prevent the accumulation of liquid water providing protection against corrosion as well as electrical shock. Here, a brief review of some of the polymeric materials under consideration for PV applications is provided, with an explanation of some of their advantages and disadvantages.

Emissions through solar PV systems - a review  

Science Journals Connector (OSTI)

Photovoltaic (PV) system has been quoted for wide range of green house gas (GHG) emissions through life cycle assessment (LCA) studies. There are a variety of solar cell materials available, which vary in conversion efficiency and emission of CO2. This paper is based on the LCA analysis of PV system which starts from the production of these solar cells and goes through the stages known as transportation, installation, operational period to their disposal or recycling and tried to find out the GHG emission in all the stages separately and the environmental impact of this emission. In this paper, different improvement techniques were also suggested to reduce the impact of GHG through solar PV system.

International PV QA Task Force's Proposed Comparative Rating System for PV Modules: Preprint  

SciTech Connect (OSTI)

The International PV Quality Assurance Task Force is developing a rating system that provides comparative information about the relative durability of PV modules. Development of accelerated stress tests that can provide such comparative information is seen as a major step toward being able to predict PV module service life. This paper will provide details of the ongoing effort to determine the format of such an overall module rating system. The latest proposal is based on using three distinct climate zones as defined in IEC 60721-2-1 for two different mounting systems. Specific stresses beyond those used in the qualification tests are being developed for each of the selected climate zones.

Study of hydrogen production system by using PV solar energy and PEM electrolyser in Algeria  

Science Journals Connector (OSTI)

Hydrogen fuel can be produced by using solar electric energy from photovoltaic (PV) modules for the electrolysis of water without emitting carbon dioxide or requiring fossil fuels. In this paper, an assessment of the technical potential for producing hydrogen from the PV/proton exchange membrane (PEM) electrolyser system is investigated. The present study estimates the amount of hydrogen produced by this system in six locations using hourly global solar irradiations on horizontal plane and ambient temperature. The system studied in this work is composed of 60W PV module connected with a commercial 50W PEM electrolyser via DC/DC converter equipped with a maximum power point tracking. The primary objective is to develop a mathematical model of hydrogen production system, including PV module and PEM electrolyser to analyze the system performance. The secondary aim is to compare the system performance in terms of hydrogen production at seven locations situated in different regions of Algeria. The amount of hydrogen produced is estimated at seven locations situated in different regions. In terms of hydrogen production, the results show that the southern region of Algeria (Adrar, Ghardaia, Bechar and Tamanrasset) is found to have the relatively highest hydrogen production. The total annual production of hydrogen is estimated to be around 2029m3 at these sites. The hydrogen production at various sites has been found to vary according to the solar radiation.

PV Manufacturing R&D Project -- Trends in the U.S. PV Industry  

SciTech Connect (OSTI)

To foster continued growth in the U.S. photovoltaic (PV) industry, the U.S. Department of Energy initiated the PV Manufacturing R&D (PVMR&D) Project--a partnership with U.S. PV industry participants to perform cost-shared manufacturing research and development. Throughout FY 2004, PVMR&D managed fourteen subcontracts across the industry. The impact of PVMR&D is quantified by reductions in direct module manufacturing costs, scale-up of existing PV production capacity, and accrual of cost savings to the public and industry. An analysis of public and industry investment shows that both recaptured funds by mid-1998 based on estimated manufacturing cost savings from PVMR&D participation. Since project inception, total PV manufacturing capacity has increased from 14 MW to 201 MW at the close of 2003, while direct manufacturing costs declined from $5.55/W to $2.49/W. These results demonstrate continued progress toward the overriding goals of the PVMR&D project.

U.S. Residential Photovoltaic (PV) System Prices, Q4 2013 Benchmarks: Cash Purchase, Fair Market Value, and Prepaid Lease Transaction Prices  

SciTech Connect (OSTI)

The price of photovoltaic (PV) systems in the United States (i.e., the cost to the system owner) has dropped precipitously in recent years, led by substantial reductions in global PV module prices. This report provides a Q4 2013 update for residential PV systems, based on an objective methodology that closely approximates the book value of a PV system. Several cases are benchmarked to represent common variation in business models, labor rates, and module choice. We estimate a weighted-average cash purchase price of $3.29/W for modeled standard-efficiency, polycrystalline-silicon residential PV systems installed in the United States. This is a 46% decline from the 2013-dollar-adjusted price reported in the Q4 2010 benchmark report. In addition, this report frames the cash purchase price in the context of key price metrics relevant to the continually evolving landscape of third-party-owned PV systems by benchmarking the minimum sustainable lease price and the fair market value of residential PV systems.

Real Power and Reactive Power Control of a Three-Phase Single-Stage-PV System and PV voltage Stability  

SciTech Connect (OSTI)

Grid-connected photovoltaic (PV) systems with power electronic interfaces can provide both real and reactive power to meet power system needs with appropriate control algorithms. This paper presents the control algorithm design for a three-phase single-stage grid-connected PV inverter to achieve either maximum power point tracking (MPPT) or a certain amount of real power injection, as well as the voltage/var control. The switching between MPPT control mode and a certain amount of real power control mode is automatic and seamless. Without the DC-to-DC booster stage, PV DC voltage stability is an important issue in the control design especially when the PV inverter is operating at maximum power point (MPP) with voltage/var control. The PV DC voltage collapse phenomenon and its reason are discussed. The method based on dynamic correction of the PV inverter output is proposed to ensure PV DC voltage stability. Simulation results of the single-stage PV system during system disturbances and fast solar irradiation changes confirm that the proposed control algorithm for single-stage PV inverters can provide appropriate real and reactive power services and ensure PV DC voltage stability during dynamic system operation and atmospheric conditions.

Integrating Solar PV in Utility System Operations  

SciTech Connect (OSTI)

This study develops a systematic framework for estimating the increase in operating costs due to uncertainty and variability in renewable resources, uses the framework to quantify the integration costs associated with sub-hourly solar power variability and uncertainty, and shows how changes in system operations may affect these costs. Toward this end, we present a statistical method for estimating the required balancing reserves to maintain system reliability along with a model for commitment and dispatch of the portfolio of thermal and renewable resources at different stages of system operations. We estimate the costs of sub-hourly solar variability, short-term forecast errors, and day-ahead (DA) forecast errors as the difference in production costs between a case with realistic PV (i.e., subhourly solar variability and uncertainty are fully included in the modeling) and a case with well behaved PV (i.e., PV is assumed to have no sub-hourly variability and can be perfectly forecasted). In addition, we highlight current practices that allow utilities to compensate for the issues encountered at the sub-hourly time frame with increased levels of PV penetration. In this analysis we use the analytical framework to simulate utility operations with increasing deployment of PV in a case study of Arizona Public Service Company (APS), a utility in the southwestern United States. In our analysis, we focus on three processes that are important in understanding the management of PV variability and uncertainty in power system operations. First, we represent the decisions made the day before the operating day through a DA commitment model that relies on imperfect DA forecasts of load and wind as well as PV generation. Second, we represent the decisions made by schedulers in the operating day through hour-ahead (HA) scheduling. Peaking units can be committed or decommitted in the HA schedules and online units can be redispatched using forecasts that are improved relative to DA forecasts, but still imperfect. Finally, we represent decisions within the operating hour by schedulers and transmission system operators as real-time (RT) balancing. We simulate the DA and HA scheduling processes with a detailed unit-commitment (UC) and economic dispatch (ED) optimization model. This model creates a least-cost dispatch and commitment plan for the conventional generating units using forecasts and reserve requirements as inputs. We consider only the generation units and load of the utility in this analysis; we do not consider opportunities to trade power with neighboring utilities. We also do not consider provision of reserves from renewables or from demand-side options. We estimate dynamic reserve requirements in order to meet reliability requirements in the RT operations, considering the uncertainty and variability in load, solar PV, and wind resources. Balancing reserve requirements are based on the 2.5th and 97.5th percentile of 1-min deviations from the HA schedule in a previous year. We then simulate RT deployment of balancing reserves using a separate minute-by-minute simulation of deviations from the HA schedules in the operating year. In the simulations we assume that balancing reserves can be fully deployed in 10 min. The minute-by-minute deviations account for HA forecasting errors and the actual variability of the load, wind, and solar generation. Using these minute-by-minute deviations and deployment of balancing reserves, we evaluate the impact of PV on system reliability through the calculation of the standard reliability metric called Control Performance Standard 2 (CPS2). Broadly speaking, the CPS2 score measures the percentage of 10-min periods in which a balancing area is able to balance supply and demand within a specific threshold. Compliance with the North American Electric Reliability Corporation (NERC) reliability standards requires that the CPS2 score must exceed 90% (i.e., the balancing area must maintain adequate balance for 90% of the 10-min periods). The combination of representing DA forecast errors in the

Ultra Accelerated Testing of PV Module Components  

SciTech Connect (OSTI)

Using concentrated natural sunlight at the NREL High Flux Solar Furnace, we have exposed several materials to acceleration factors of up to 400 times the normal outdoor UV exposure dose. This accelerated rate allows the exposure of materials such that a year of outdoor exposure can be simulated in about 5 hours. We have studied the solarization of cerium containing glass, the degradation of ethylene vinyl acetate laminated between borosilicate glass, and the yellowing of standard polystyrene test coupons. The first two candidates are of interest to the photovoltaics (PV) program, and the last candidate material is a widely used dosimeter for ultra violet (UV) exposure in accelerated weathering chambers

Development of a Dispatchable PV Peak Shainv System. PV: Bonus Program - Phase 1 Report. Volume 1  

SciTech Connect (OSTI)

This report summarizes the work performed by Delmarva Power and Light and its subcontractors in Phase 1 of the US Department of Energy's PV:BONUS Program. The purpose of the program is to develop products and systems for buildings which utilize photovoltaic (N) technology. Beginning with a cooperative research effort with the University of Delaware's Center for Energy and Environmental Policy Research Delmarva Power developed and demonstrated the concept of Dispatchable PV Peak Shaving. This concept and the system which resulted horn the development work are unique from other grid-connected PV systems because it combines a PV, battery energy storage, power conversion and control technologies into an integrated package. Phase 1 began in July 1993 with the installation of a test and demonstration system at Delmarva's Northern Division General Office building near Newark, Delaware. Following initial testing throughout the summer and fall of 1993, significant modifications were made under an amendment to the DOE contract. Work on Phase 1 concluded in the early spring of 1995. Significant progress towards the goal of commercializing the system was made during Phase 1, and is summarized. Based on progress in Phase 1, a proposal to continue the work in Phase 2 was submitted to the US DOE in May 1995. A contract amendment and providing funds for the Phase 2 work is expected in July 1995.

Molecular structure calculations: A unified quantum mechanical description of electrons and nuclei using explicitly correlated Gaussian functions and the global vector representation  

SciTech Connect (OSTI)

We elaborate on the theory for the variational solution of the Schroedinger equation of small atomic and molecular systems without relying on the Born-Oppenheimer paradigm. The all-particle Schroedinger equation is solved in a numerical procedure using the variational principle, Cartesian coordinates, parameterized explicitly correlated Gaussian functions with polynomial prefactors, and the global vector representation. As a result, non-relativistic energy levels and wave functions of few-particle systems can be obtained for various angular momentum, parity, and spin quantum numbers. A stochastic variational optimization of the basis function parameters facilitates the calculation of accurate energies and wave functions for the ground and some excited rotational-(vibrational-)electronic states of H{sub 2}{sup +} and H{sub 2}, three bound states of the positronium molecule, Ps{sub 2}, and the ground and two excited states of the {sup 7}Li atom.

Analytical Improvements in PV Degradation Rate Determination  

SciTech Connect (OSTI)

As photovoltaic (PV) penetration of the power grid increases, it becomes vital to know how decreased power output may affect cost over time. In order to predict power delivery, the decline or degradation rates must be determined accurately. For non-spectrally corrected data several complete seasonal cycles (typically 3-5 years) are required to obtain reasonably accurate degradation rates. In a rapidly evolving industry such a time span is often unacceptable and the need exists to determine degradation rates accurately in a shorter period of time. Occurrence of outliers and data shifts are two examples of analytical problems leading to greater uncertainty and therefore to longer observation times. In this paper we compare three methodologies of data analysis for robustness in the presence of outliers, data shifts and shorter measurement time periods.

Electrochemical Approaches to PV Busbar Application  

SciTech Connect (OSTI)

Busbars are an integral component of any thin-film photovoltaic module and must be easy and quick to apply by PV manufacturers, as well as provide long-term reliability in deployed modules. Potential reliability issues include loss of adhesion and delamination, chemical instability under current collection conditions (electromigration or corrosion), compatibility of material and application method with subsequent encapsulation steps. Several new and novel busbar materials and application methods have been explored, including adhering metal busbars with various one- and two-part conductive epoxies or conductive adhesive films, ultrasonic bonding of metal busbar strips, and bonding of busbar strips using low-temperature solders. The most promising approach to date has been the direct application of metal busbars via various electrochemical techniques, which offers a variety of distinct advantages.

Kauai Island Utility Co-op (KIUC) PV integration study.  

SciTech Connect (OSTI)

This report investigates the effects that increased distributed photovoltaic (PV) generation would have on the Kauai Island Utility Co-op (KIUC) system operating requirements. The study focused on determining reserve requirements needed to mitigate the impact of PV variability on system frequency, and the impact on operating costs. Scenarios of 5-MW, 10-MW, and 15-MW nameplate capacity of PV generation plants distributed across the Kauai Island were considered in this study. The analysis required synthesis of the PV solar resource data and modeling of the KIUC system inertia. Based on the results, some findings and conclusions could be drawn, including that the selection of units identified as marginal resources that are used for load following will change; PV penetration will displace energy generated by existing conventional units, thus reducing overall fuel consumption; PV penetration at any deployment level is not likely to reduce system peak load; and increasing PV penetration has little effect on load-following reserves. The study was performed by EnerNex under contract from Sandia National Laboratories with cooperation from KIUC.

Full Steam Ahead for PV in US Homes?  

SciTech Connect (OSTI)

In October 2008, the United States Congress extended both the residential and commercial solar investment tax credits (ITCs) for an unprecedented eight years, lifted the $2,000 cap on the residential credit, removed the prohibition on utility use of the commercial credit, and eliminated restrictions on the use of both credits in conjunction with the Alternative Minimum Tax. These significant changes, which apply to systems placed in service on or after January 1, 2009, will increase the value of the solar credits for residential system owners in particular, and are likely--in conjunction with state, local, and utility rebate programs targeting solar--to spur significant growth in residential, commercial, and utility-scale photovoltaic (PV) installations in the years ahead. This article focuses specifically on the residential credit, describing three areas in which removal of the $2,000 cap on the residential ITC will have significant implications for PV rebate program administrators, PV system owners, and the PV industry.

Interconnecting PV on New York City's Secondary Network Distribution System  

SciTech Connect (OSTI)

The U.S. Department of Energy (DOE) has teamed with cities across the country through the Solar America Cities (SAC) partnership program to help reduce barriers and accelerate implementation of solar energy. The New York City SAC team is a partnership between the City University of New York (CUNY), the New York City Mayor s Office of Long-term Planning and Sustainability, and the New York City Economic Development Corporation (NYCEDC).The New York City SAC team is working with DOE s National Renewable Energy Laboratory (NREL) and Con Edison, the local utility, to develop a roadmap for photovoltaic (PV) installations in the five boroughs. The city set a goal to increase its installed PV capacity from1.1 MW in 2005 to 8.1 MW by 2015 (the maximum allowed in 2005). A key barrier to reaching this goal, however, is the complexity of the interconnection process with the local utility. Unique challenges are associated with connecting distributed PV systems to secondary network distribution systems (simplified to ???¢????????networks???¢??????? in this report). Although most areas of the country use simpler radial distribution systems to distribute electricity, larger metropolitan areas like New York City typically use networks to increase reliability in large load centers. Unlike the radial distribution system, where each customer receives power through a single line, a network uses a grid of interconnected lines to deliver power to each customer through several parallel circuits and sources. This redundancy improves reliability, but it also requires more complicated coordination and protection schemes that can be disrupted by energy exported from distributed PV systems. Currently, Con Edison studies each potential PV system in New York City to evaluate the system s impact on the network, but this is time consuming for utility engineers and may delay the customer s project or add cost for larger installations. City leaders would like to streamline this process to facilitate faster, simpler, and less expensive distributed PV system interconnections. To assess ways to improve the interconnection process, NREL conducted a four-part study with support from DOE. The NREL team then compiled the final reports from each study into this report. In Section 1???¢????????PV Deployment Analysis for New York City???¢????????we analyze the technical potential for rooftop PV systems in the city. This analysis evaluates potential PV power production in ten Con Edison networks of various locations and building densities (ranging from high density apartments to lower density single family homes). Next, we compare the potential power production to network loads to determine where and when PV generation is most likely to exceed network load and disrupt network protection schemes. The results of this analysis may assist Con Edison in evaluating future PV interconnection applications and in planning future network protection system upgrades. This analysis may also assist other utilities interconnecting PV systems to networks by defining a method for assessing the technical potential of PV in the network and its impact on network loads. Section 2???¢????????A Briefing for Policy Makers on Connecting PV to a Network Grid???¢????????presents an overview intended for nontechnical stakeholders. This section describes the issues associated with interconnecting PV systems to networks, along with possible solutions.

Continuing Developments in PV Risk Management: Strategies, Solutions, and Implications  

SciTech Connect (OSTI)

As the PV industry matures, successful risk management practices will become more imperative to ensure investor confidence, control costs, and facilitate further growth. This report discusses several key aspects of risk management during the commercial- and utility-scale project life cycle, from identification of risks, to the process of mitigating and allocating those risks among project parties, to transferring those risks through insurance. The report also explores novel techniques in PV risk management, options to offload risks onto the capital markets, and innovative insurance policies (namely warranty policies) that address risks unique to the PV sector. One of the major justifications for robust risk management in the PV industry is the cost-reduction opportunities it affords. If the PV industry can demonstrate the capability to successfully manage its risks, thereby inspiring confidence in financiers, it may be able to obtain a lower cost of capital in future transactions. A lower cost of capital translates to a lower cost of energy, which will in turn enhance PV?s competitiveness at a time when it will have to rely less on subsidies to support its market penetration.

How Can We Make PV Modules Safer?: Preprint  

SciTech Connect (OSTI)

Safety is a prime concern for the photovoltaics (PV) industry. As a technology deployed on residential and commercial buildings, it is critical that PV not cause damage to the buildings nor harm the occupants. Many of the PV systems on buildings are of sufficiently high voltage (300 to 600 Volts dc) that they may present potential hazards. These PV systems must be safe in terms of mechanical damage (nothing falls on someone), shock hazard (no risk of electrical shock when touching an exposed circuit element), and fire (the modules neither cause nor promote a fire). The present safety standards (IEC 61730 and UL 1703) do a good job of providing for design rules and test requirements for mechanical, shock, and spread of flame dangers. However, neither standard addresses the issue of electrical arcing within a module that can cause a fire. To make PV modules, they must be designed, built, and installed with an emphasis on minimizing the potential for open circuits and ground faults. This paper provides recommendations on redundant connection designs, robust mounting methods, and changes to the safety standards to yield safer PV modules.

Review of PV Inverter Technology Cost and Performance Projections  

SciTech Connect (OSTI)

The National Renewable Energy Laboratory (NREL) has a major responsibility in the implementation of the U.S. Department of Energy's (DOE's) Solar Energy Technologies Program. Sandia National Laboratories (SNL) has a major role in supporting inverter development, characterization, standards, certifications, and verifications. The Solar Energy Technologies Program recently published a Multiyear Technical Plan, which establishes a goal of reducing the Levelized Energy Cost (LEC) for photovoltaic (PV) systems to $0.06/kWh by 2020. The Multiyear Technical Plan estimates that, in order to meet the PV system goal, PV inverter prices will need to decline to $0.25-0.30 Wp by 2020. DOE determined the need to conduct a rigorous review of the PV Program's technical and economic targets, including the target set for PV inverters. NREL requested that Navigant Consulting Inc.(NCI) conduct a review of historical and projected cost and performance improvements for PV inverters, including identification of critical barriers identified and the approaches government might use to address them.

Off-grid Solar PV Power for Humanitarian Action: From Emergency Communications to Refugee Camp Micro-grids  

Science Journals Connector (OSTI)

Abstract The need for new innovative technologies to support humanitarian action is evident today. Efficient and economic technologies properly deployed and integrated should mitigate some of the potential negative social effects of poor refugee camp infrastructure engineering. The body of the paper identifies off-grid solar Photovoltaic (PV) and solar PV hybrid packaged systems that are applicable to emergency relief activities, refugee camp activities and micro-grid development. The paper's concentration on off-grid power, the description of these engineered systems by humanitarian activity and the identification of the different engineered packaged solutions is aimed at stimulating a discussion to help scale more appropriate technologies for humanitarian action. The paper concludes with a discussion of present and future private sector business strategies to support scalability of this new and growing market.

Solar ADEPT Project: PV inverters convert DC power generated by modules into usable AC power. IPCs initial 30kW 94lb. PV inverter reduces the weight of comparable 30kW PV inverters by 90%reducing the cost of materials, manufacturing, shipping, and installation. With ARPA-E support, new bi-directional silicon power switches will be developed, commercialized, and utilized in IPCs next-generation PV inverter. With these components, IPC will produce 100kW inverters that weight less than 100lb., reducing the weight of conventional 3,000lb. 100kW inverters by more than 95%. The new power switches will cut IPCs $/W manufacturing cost in half, as well as further reduce indirect shipping and installation costs.

Viability analysis of PV power plants in Egypt  

Science Journals Connector (OSTI)

This paper investigates, from techno-economical and environmental points of view, the feasible sites in Egypt to build a 10MW PV-grid connected power plant. Available PV-modules are assessed and a module is selected for this study. The long-term meteorological parameters for each of the 29 considered sites in Egypt from NASA renewable energy resource website (Surface meteorology and Solar Energy) are collected and analyzed in order to study the behaviors of solar radiations, sunshine duration, air temperature, and humidity over Egypt, and also to determine the compatibility of the meteorological parameters in Egypt with the safety operating conditions (SOC) of PV-modules. The project viability analysis is performed using \\{RETScreen\\} version 4.0 software through electric energy production analysis, financial analysis, and GHG emission analysis. The study show that placement of the proposed 10MW PV-grid connected power plant at Wahat Kharga site offers the highest profitability, energy production, and GHG emission reduction. The lowest profitability and energy production values are offered at Safaga site. Therefore, it is recommended to start building large-scale PV power plants projects at Wahat Kharga site.

PV Cell and Module Calibration Activities at NREL  

SciTech Connect (OSTI)

The performance of PV cells and modules with respect to standard reference conditions is a key indicator of progress of a given technology. This task provides the U.S. terrestrial PV community with the most accurate measurements that are technically possible in a timely fashion. The international module certification and accreditation program PVGap requires certification laboratories to maintain their calibration traceability path to groups like this one. The politics of a "world record" efficiency requires that an independent laboratory perform these measurements for credibility. Most manufacturers base their module peak watt rating upon standards and reference cells calibrated under this task. This task has been involved in reconciling disputes between manufacturers and their cell suppliers in terms of expected versus actual performance. This task has also served as a resource to the PV community for consultation on solar simulation, current versus voltage measurement instrumentation, measurement procedures and measurement artifacts.

Time series power flow analysis for distribution connected PV generation.  

SciTech Connect (OSTI)

Distributed photovoltaic (PV) projects must go through an interconnection study process before connecting to the distribution grid. These studies are intended to identify the likely impacts and mitigation alternatives. In the majority of the cases, system impacts can be ruled out or mitigation can be identified without an involved study, through a screening process or a simple supplemental review study. For some proposed projects, expensive and time-consuming interconnection studies are required. The challenges to performing the studies are twofold. First, every study scenario is potentially unique, as the studies are often highly specific to the amount of PV generation capacity that varies greatly from feeder to feeder and is often unevenly distributed along the same feeder. This can cause location-specific impacts and mitigations. The second challenge is the inherent variability in PV power output which can interact with feeder operation in complex ways, by affecting the operation of voltage regulation and protection devices. The typical simulation tools and methods in use today for distribution system planning are often not adequate to accurately assess these potential impacts. This report demonstrates how quasi-static time series (QSTS) simulation and high time-resolution data can be used to assess the potential impacts in a more comprehensive manner. The QSTS simulations are applied to a set of sample feeders with high PV deployment to illustrate the usefulness of the approach. The report describes methods that can help determine how PV affects distribution system operations. The simulation results are focused on enhancing the understanding of the underlying technical issues. The examples also highlight the steps needed to perform QSTS simulation and describe the data needed to drive the simulations. The goal of this report is to make the methodology of time series power flow analysis readily accessible to utilities and others responsible for evaluating potential PV impacts.

Outdoor PV Module Degradation of Current-Voltage Parameters: Preprint  

SciTech Connect (OSTI)

Photovoltaic (PV) module degradation rate analysis quantifies the loss of PV power output over time and is useful for estimating the impact of degradation on the cost of energy. An understanding of the degradation of all current-voltage (I-V) parameters helps to determine the cause of the degradation and also gives useful information for the design of the system. This study reports on data collected from 12 distinct mono- and poly-crystalline modules deployed at the National Renewable Energy Laboratory (NREL) in Golden, Colorado. Most modules investigated showed < 0.5%/year decrease in maximum power due to short-circuit current decline.

Development of an economical model to determine an appropriate feed-in tariff for grid-connected solar PV electricity in all states of Australia  

Science Journals Connector (OSTI)

Australia is a country with a vast amount of natural resources including sun and wind. Australia lies between latitude of 1045S and longitude of 112152E, with a daily solar exposure of between less than 3MJ/(m2day) in winter and more than 30MJ/(m2day) in summer. Global solar radiation in Australia varies between minimum of 3285MJ/(m2year) in Hobart to 8760MJ/(m2year) in Northern Territory. As a result of this wide range of radiation level there will be a big difference between costs of solar PV electricity in different locations. A study we have recently conducted on the solar PV electricity price in all states of Australia. For this purpose we have developed an economical model and a computer simulation to determine the accurate unit price of grid-connected roof-top solar photovoltaic (PV) electricity in A$/kWh for all state of Australia. The benefit of this computer simulation is that we can accurately determine the most appropriate feed-in tariff of grid-connected solar PV energy system. The main objective of this paper is to present the results of this study. A further objective of this paper is to present the details of the unit price of solar PV electricity in the state of Victoria in each month and then to compare with electricity price from conventional power systems, which is currently applied to this state. The state Victoria is located south of Australia and in terms of sun radiation is second lowest compared with the other Australian states. The computer simulation developed for this study makes it possible to determine the cost of grid-connected solar PV electricity at any location in any country based on availability of average daily solar exposure of each month as well as economical factors of the country.

Fault Current Contribution from Single-Phase PV Inverters  

SciTech Connect (OSTI)

A significant increase in photovoltaic (PV) system installations is expected to come on line in the near future and as the penetration level of PV increases, the effect of PV may no longer be considered minimal. One of the most important attributions of additional PV is what effect this may have on protection systems. Protection engineers design protection systems to safely eliminate faults from the electric power system. One of the new technologies recently introduced into the electric power system are distributed energy resources (DER). Currently, inverter-based DER contributes very little to the power balance on all but a few utility distribution systems. As DER become prevalent in the distribution system, equipment rating capability and coordination of protection systems merit a closer investigation. A collaborative research effort between the National Renewable Energy Laboratory (NREL) and Southern California Edison (SCE) involved laboratory short-circuit testing single-phase (240 VAC) residential type (between 1.5 and 7kW) inverters. This paper will reveal test results obtained from these short-circuit tests.

Integrating High Penetrations of PV into Southern California: Year 2 Project Update; Preprint  

SciTech Connect (OSTI)

Southern California Edison (SCE) is well into a five-year project to install a total of 500 MW of distributed photovoltaic (PV) energy within its utility service territory. Typical installations to date are 1-3 MW peak rooftop PV systems that interconnect to medium-voltage urban distribution circuits or larger (5 MW peak) ground-mounted systems that connect to medium-voltage rural distribution circuits. Some of the PV system interconnections have resulted in distribution circuits that have a significant amount of PV generation compared to customer load, resulting in high-penetration PV integration scenarios. The National Renewable Energy Laboratory (NREL) and SCE have assembled a team of distribution modeling, resource assessment, and PV inverter technology experts in order to investigate a few of the high-penetration PV distribution circuits. Currently, the distribution circuits being studied include an urban circuit with a PV penetration of approximately 46% and a rural circuit with a PV penetration of approximately 60%. In both cases, power flow on the circuit reverses direction, compared to traditional circuit operation, during periods of high PV power production and low circuit loading. Research efforts during year two of the five-year project were focused on modeling the distribution system level impacts of high-penetration PV integrations, the development and installation of distribution circuit data acquisition equipment appropriate for quantifying the impacts of high-penetration PV integrations, and investigating high-penetration PV impact mitigation strategies. This paper outlines these research efforts and discusses the following activities in more detail: the development of a quasi-static time-series test feeder for evaluating high-penetration PV integration modeling tools; the advanced inverter functions being investigated for deployment in the project's field demonstration and a power hardware-in-loop test of a 500-kW PV inverter implementing a limited set of advanced inverter functions.

Sensitivity of Rooftop PV Projections in the SunShot Vision Study to Market Assumptions  

SciTech Connect (OSTI)

The SunShot Vision Study explored the potential growth of solar markets if solar prices decreased by about 75% from 2010 to 2020. The SolarDS model was used to simulate rooftop PV demand for this study, based on several PV market assumptions--future electricity rates, customer access to financing, and others--in addition to the SunShot PV price projections. This paper finds that modeled PV demand is highly sensitive to several non-price market assumptions, particularly PV financing parameters.

Living on PV power in comfort and style  

SciTech Connect (OSTI)

The Solectrogen House near San Francisco was conceived, designed and built by Solar Depot as an off-grid renewable energy house. It is powered by a Solectrogen Hybrid Power System consisting of a 3 kW PV array, two 1 kW wind powered generators, a 50 kWh storage battery bank and a 6.5 kW LP-fueled engine generator for back-up. Two 4kW sinewave DC to AC inverters are utilized, with 24 VDC input and 120/240 VAC 60 Hz output. The inverters are equipped with built-in battery chargers and microprocessors for controlling the engine generator operation. The water supply of the house is a well pumped by a PV powered submersible DC pump. The swimming pool filtration system utilizes a 3/4 HP DC pump powered by a separate dedicated PV array of 640 Watts at 90 V. Energy efficient lighting and refrigeration used in the house minimize the power requirements of the house. The house also utilizes a solar thermal system consisting of 640 sq. ft. of glazed solar collectors and a 500 gallon storage tank. The thermal system is utilized for heating water year round, for space heating in the winter and for swimming pool heating in the summer.

Exploring the Economic Value of EPAct 2005's PV Tax Credits  

SciTech Connect (OSTI)

This CESA - LBNL Case Study examines how much economic value do new and expanded federal tax credits really provide to PV system purchasers, and what implications might they hold for state/utility PV grant programs. The report begins with a discussion of the taxability of PV grants and their interaction with federal credits, as this issue significantly affects the analysis that follows. We then calculate the incremental value of EPAct's new and expanded credits for PV systems of different sizes, and owned by different types of entities. The report concludes with a discussion of potential implications for purchasers of PV systems, as well as for administrators of state/utility PV programs. The market for grid-connected photovoltaics (PV) in the US has grown dramatically in recent years, driven in large part by PV grant or 'buy-down' programs in California, New Jersey, and many other states. The recent announcement of a new 11-year, $3.2 billion PV program in California suggests that state policy will continue to drive even faster growth over the next decade. Federal policy has also played a role, primarily by providing commercial PV systems access to tax benefits, including accelerated depreciation (5-year MACRS schedule) and a business energy investment tax credit (ITC). Since the signing of the Energy Policy Act of 2005 (EPAct) on August 8, the federal government has begun to play a much more significant role in supporting both commercial and residential PV systems. Specifically, EPAct increased the federal ITC for commercial PV systems from 10% to 30% of system costs, and also created a new 30% ITC (capped at $2000) for residential solar systems. Both changes went into effect on January 1, 2006, for an initial period of two years, and in late 2006 were extended for an additional year. Unless extended further, the new residential ITC will expire, and the 30% commercial ITC will revert back to 10%, on January 1, 2009. How much economic value do these new and expanded federal tax credits really provide to PV system purchasers? And what implications might they hold for state/utility PV grant programs? Using a generic (i.e., non-state-specific) cash flow model, this report explores these questions.1 We begin with a discussion of the taxability of PV grants and their interaction with federal credits, as this issue significantly affects the analysis that follows. We then calculate the incremental value of EPAct's new and expanded credits for PV systems of different sizes, and owned by different types of entities. We conclude with a discussion of potential implications for purchasers of PV systems, as well as for administrators of state/utility PV programs.

PV Analyst: Coupling ArcGIS with TRNSYS to assess distributed photovoltaic potential in urban areas  

Science Journals Connector (OSTI)

This study presents a means to extend the functionality of Geographic Information Systems (GIS) in assessing distributed photovoltaic (PV) potential in urban areas, via the new ArcGIS extension: PV Analyst. A methodology is proposed for coupling ArcGIS with TRNSYS that enables the PV Analyst extension to use the capabilities of 4 and 5-parameter PV array performance models and the irradiance components in TRNSYS for solar energy simulations in geospatial contexts. Because PV Analyst is embedded within the ArcMap environment, part of ArcGIS software package, the strong capabilities of ArcGIS and other ArcGIS extensions such as 3D Analyst, Spatial Analyst and Tracking Analyst can be fully utilized with PV Analysts functionalities. This paper describes the concept and details of the extension development, as well as its application to the Pollock Commons area at the Pennsylvania State University.

Is Germany?s energy transition a case of successful green industrial policy? Contrasting wind and solar PV  

Science Journals Connector (OSTI)

Abstract In this paper, we address the challenge of Germany?s energy transition (Energiewende) as the centrepiece of the country?s green industrial policy. In addition to contributing to global climate change objectives, the Energiewende is intended to create a leading position for German industry in renewable energy technologies, boost innovative capabilities and create employment opportunities in future growth markets at the least possible cost. The success in reaching these aims, and indeed the future of the entire concept, is hotly debated. The paper aims to provide an up-to-date assessment of what has become a fierce controversy by comparing solar photovoltaic (PV) and wind energy along five policy objectives: (1) competitiveness, (2) innovation, (3) job creation, (4) climate change mitigation, and (5) cost. We find mixed evidence that Germany reaches its green industrial policy aims at reasonable costs. Wind energy seems to perform better against all policy objectives, while the solar PV sector has come under intense pressure from international competition. However, this is only a snapshot of current performance, and the long term and systemic perspective required for the energy sector transformation suggests a need for a balanced mix of a variety of clean energy sources.

Analysis of off-grid hybrid wind turbine/solar PV water pumping systems  

Science Journals Connector (OSTI)

While many remote water pumping systems exist (e.g. mechanical windmills, solar photovoltaic, wind-electric, diesel powered), few combine both the wind and solar energy resources to possibly improve the reliability and the performance of the system. In this paper, off-grid wind turbine (WT) and solar photovoltaic (PV) array water pumping systems were analyzed individually and combined as a hybrid system. The objectives were to determine: (1) advantages or disadvantages of using a hybrid system over using a WT or a solar PV array alone; (2) if the WT or solar PV array interfered with the output of the other; and (3) which hybrid system was the most efficient for the location. The WT used in the analysis was rated at 900W alternating current (AC). There were three different solar PV arrays analyzed, and they were rated at 320, 480, and 640W direct current (DC). A rectifier converted the 3-phase variable voltage AC output from the WT to DC before combining it with the solar PV array DC output. The combined renewable energies powered a single helical pump. The independent variable used in the hybrid WT/PV array analysis was in units of W/m2. The peak pump efficiency of the hybrid systems at Bushland, TX occurred for the 900W WT combined with the 640W PV array. The peak pump efficiencies at a 75m pumping depth of the hybrid systems were: 47% (WT/320W PV array), 51% (WT/480W PV array), and 55% (WT/640W PV array). Interference occurred between the WT and the different PV arrays (likely due to voltage mismatch between WT and PV array), but the least interference occurred for the WT/320W PV array. This hybrid system pumped 28% more water during the greatest water demand month than the WT and PV systems would have pumped individually. An additional controller with a buck/boost converter is discussed at end of paper for improvement of the hybrid WT/PV array water pumping system.

Future of Grid-Tied PV Business Models: What Will Happen When PV Penetration on the Distribution Grid is Significant? Preprint  

SciTech Connect (OSTI)

Eventually, distributed PV will become a more significant part of the generation mix. When this happens, it is expected that utilities will have to take on a more active role in the placement, operation and control of these systems. There are operational complexities and concerns of revenue erosion that will drive utilities into greater involvement of distributed PV and will create new business models. This report summarizes work done by Navigant Consulting Inc. for the National Renewable Energy Laboratory as part of the Department of Energy's work on Renewable System Integration. The objective of the work was to better understand the structure of these future business models and the research, development and demonstration (RD&D) required to support their deployment. This report describes potential future PV business models in terms of combinations of utility ownership and control of the PV assets, and the various relationships between end-users and third-party owners.

Creating dynamic equivalent PV circuit models with impedance spectroscopy for arc-fault modeling.  

SciTech Connect (OSTI)

Article 690.11 in the 2011 National Electrical Code{reg_sign} (NEC{reg_sign}) requires new photovoltaic (PV) systems on or penetrating a building to include a listed arc fault protection device. Currently there is little experimental or empirical research into the behavior of the arcing frequencies through PV components despite the potential for modules and other PV components to filter or attenuate arcing signatures that could render the arc detector ineffective. To model AC arcing signal propagation along PV strings, the well-studied DC diode models were found to inadequately capture the behavior of high frequency arcing signals. Instead dynamic equivalent circuit models of PV modules were required to describe the impedance for alternating currents in modules. The nonlinearities present in PV cells resulting from irradiance, temperature, frequency, and bias voltage variations make modeling these systems challenging. Linearized dynamic equivalent circuits were created for multiple PV module manufacturers and module technologies. The equivalent resistances and capacitances for the modules were determined using impedance spectroscopy with no bias voltage and no irradiance. The equivalent circuit model was employed to evaluate modules having irradiance conditions that could not be measured directly with the instrumentation. Although there was a wide range of circuit component values, the complex impedance model does not predict filtering of arc fault frequencies in PV strings for any irradiance level. Experimental results with no irradiance agree with the model and show nearly no attenuation for 1 Hz to 100 kHz input frequencies.

Abstract Short-term variability in the power generated by utility-scale solar photovoltaic (PV) plants is a cause for concern for power system operators. Without quantitative insights into such variability, system operators will have difficulty in exploiting grid integrated solar power without negatively impacting power quality and grid reliability. In this paper, we describe a statistical method to empirically model the ramping behavior of utility-scale solar PV power output for short time-scales. The general validity of the model is confirmed through the analysis of power output data from a MW-scale solar PV plant located in the state of Karnataka, India. The empirical parameters of the model are investigated for different time-intervals and solar datasets. The proposed model is able to satisfactorily approximate the actual distribution of PV ramp events and can be an effective tool in smartly planning additional resources for PV ramp control.

Technical and economical system comparison of photovoltaic and concentrating solar thermal power systems depending on annual global irradiation  

Science Journals Connector (OSTI)

Concentrating solar thermal power and photovoltaics are two major technologies for converting sunlight to electricity. Variations of the annual solar irradiation depending on the site influence their annual efficiency, specific output and electricity generation cost. Detailed technical and economical analyses performed with computer simulations point out differences of solar thermal parabolic trough power plants, non-tracked and two-axis-tracked PV systems. Therefore, 61 sites in Europe and North Africa covering a global annual irradiation range from 923 to 2438 kWh/m2a have been examined. Simulation results are usable irradiation by the systems, specific annual system output and levelled electricity cost. Cost assumptions are made for today's cost and expected cost in 10 years considering different progress ratios. This will lead to a cost reduction by 50% for PV systems and by 40% for solar thermal power plants. The simulation results show where are optimal regions for installing solar thermal trough and tracked PV systems in comparison to non-tracked PV. For low irradiation values the annual output of solar thermal systems is much lower than of PV systems. On the other hand, for high irradiations solar thermal systems provide the best-cost solution even when considering higher cost reduction factors for PV in the next decade. Electricity generation cost much below 10 Eurocents per kWh for solar thermal systems and about 12 Eurocents/kWh for PV can be expected in 10 years in North Africa.

Fundamentals of PV Efficiency: Limits for Light Absorption  

E-Print Network [OSTI]

A simple thermodynamic argument related to a (weakly absorbing) finite dielectric slab illuminated by sunlight- originally suggested by Yablonovich- leads to the conclusion that the absorption in a dielectric can at best be increased by a factor 4n2. Therefore, the absorption in these materials is always imperfect; the Shockley-Queisser limit can be achieved only asymptotically. In this paper, we make the connection between the degradation in efficiency and the Yablonovich limit explicit and re-derive the 4n2 limit by intuitive geometrical arguments based on Snell's law and elementary rules of probability. Remarkably, the re-derivation suggests strategies of breaking the traditional limit and improving PV efficiency by enhanced light absorption.

Policy target, feed-in tariff, and technological progress of PV in Taiwan  

Science Journals Connector (OSTI)

Abstract It is widely recognized that solar energy, a major renewable energy source, can strengthen a country?s energy security and reduce CO2 emissions. For this reason, Taiwan aims to develop its solar power industry by promoting photovoltaic (PV) applications. To meet its PV installation targets, the government is considering adopting feed-in tariffs (FITs), offering subsidies on capital expenditures, and funding research and development. At present, there is a wide gap between the country?s installed capacity and the long-term government targets. Therefore, this study constructs a PV supply curve to demonstrate the potential contribution of PV power to Taiwan?s electricity requirements. Based on this curve, an assessment tool is developed to show the relationship between PV installed capacity and energy cost reductions under a FIT scheme. Using this assessment model, policymakers can simulate the adoption of PV projects at the county level and anticipate possible challenges. Furthermore, the model will also measure the level of cost reductions required for PV technology to reach specific targets under the FIT scheme.

Advanced Inverter Technology for High Penetration Levels of PV Generation in Distribution Systems  

SciTech Connect (OSTI)

This subcontract report was completed under the auspices of the NREL/SCE High-Penetration Photovoltaic (PV) Integration Project, which is co-funded by the U.S. Department of Energy (DOE) Office of Energy Efficiency and Renewable Energy (EERE) and the California Solar Initiative (CSI) Research, Development, Demonstration, and Deployment (RD&D) program funded by the California Public Utility Commission (CPUC) and managed by Itron. This project is focused on modeling, quantifying, and mitigating the impacts of large utility-scale PV systems (generally 1-5 MW in size) that are interconnected to the distribution system. This report discusses the concerns utilities have when interconnecting large PV systems that interconnect using PV inverters (a specific application of frequency converters). Additionally, a number of capabilities of PV inverters are described that could be implemented to mitigate the distribution system-level impacts of high-penetration PV integration. Finally, the main issues that need to be addressed to ease the interconnection of large PV systems to the distribution system are presented.

Overview of Scientific Issues Involved in Selection of Polymers for PV Applications  

SciTech Connect (OSTI)

Encapsulant materials used in photovoltaic (PV) modules serve multiple purposes. They physically hold components in place, provide electrical insulation, reduce moisture ingress, optically couple superstrate materials (e.g., glass) to PV cells, protect components from mechanical stress by mechanically decoupling components via strain relief, and protect materials from corrosion. To do this, encapsulants must adhere well to all surfaces, remain compliant, and transmit light after exposure to temperature, humidity, and UV radiation histories. Here, a brief review of some of the polymeric materials under consideration for PV applications is provided, with an explanation of some of their advantages and disadvantages.

Validation of PV performance models using satellite-based irradiance measurements : a case study.  

SciTech Connect (OSTI)

Photovoltaic (PV) system performance models are relied upon to provide accurate predictions of energy production for proposed and existing PV systems under a wide variety of environmental conditions. Ground based meteorological measurements are only available from a relatively small number of locations. In contrast, satellite-based radiation and weather data (e.g., SUNY database) are becoming increasingly available for most locations in North America, Europe, and Asia on a 10 x 10 km grid or better. This paper presents a study of how PV performance model results are affected when satellite-based weather data is used in place of ground-based measurements.

NREL/SCE High-Penetration PV Integration Project: Report on Field Demonstration of Advanced Inverter Functionality in Fontana, CA  

SciTech Connect (OSTI)

The National Renewable Energy Laboratory/Southern California Edison High-Penetration PV Integration Project is (1) researching the distribution system level impacts of high-penetration photovoltaic (PV) integration, (2) determining mitigation methods to reduce or eliminate those impacts, and (3) seeking to demonstrate these mitigation methods on actual high-penetration PV distribution circuits. This report describes a field demonstration completed during the fall of 2013 on the Fontana, California, study circuit, which includes a total of 4.5 MW of interconnected utility-scale rooftop PV systems. The demonstration included operating a 2-MW PV system at an off-unity power factor that had been determined during previously completed distribution system modeling and PV impact assessment analyses. Data on the distribution circuit and PV system operations were collected during the 2-week demonstration period. This demonstration reinforces the findings of previous laboratory testing that showed that utility-scale PV inverters are capable of operating at off-unity power factor to mitigate PV impacts; however, because of difficulties setting and retaining PV inverter power factor set points during the field demonstration, it was not possible to demonstrate the effectiveness of off-unity power factor operation to mitigate the voltage impacts of high-penetration PV integration. Lessons learned from this field demonstration are presented to inform future field demonstration efforts.

Why Are Residential PV Prices in Germany So Much Lower Than in the United Why Are Residential PV Prices in Germany So Much Lower Than in the United States? Speaker(s): Joachim Seel Date: April 11, 2013 - 12:00pm Location: 90-3122 Seminar Host/Point of Contact: Ryan Wiser The installed price of residential PV is significantly lower in Germany than in the United States - in Q3 2012 German systems were priced on average at $2.50/W while U.S. systems were priced nearly twice as high around $5.20/W. These pricing differences accumulate to about $13,500 for a 5kW residential system and stem primarily from differences in "soft" costs, but little detail is known about how soft cost components differ between the two countries, or why. In order to better characterize the nature of these differences, LBNL fielded surveys of German PV installers,

Diffusion of environmentally-friendly energy technologies: buy versus lease differences in residential PV markets  

Science Journals Connector (OSTI)

Diffusion of microgeneration technologies, particularly rooftop photovoltaic (PV), represents a key option in reducing emissions in the residential sector. We use a uniquely rich dataset from the burgeoning residential PV market in Texas to study the nature of the consumer's decision-making process in the adoption of these technologies. In particular, focusing on the financial metrics and the information decision-makers use to base their decisions upon, we study how the leasing and buying models affect individual choices and, thereby, the adoption of capital-intensive energy technologies. Overall, our findings suggest that the leasing model more effectively addresses consumers' informational requirements and that, contrary to some other studies, buyers and lessees of PV do not necessarily differ significantly along socio-demographic variables. Instead, we find that the leasing model has opened up the residential PV market to a new, and potentially very large, consumer segmentthose with a tight cash-flow situation.

Comparison of two techniques for the simulation of PV systems  

SciTech Connect (OSTI)

For several years, MIT Lincoln Laboratory has conducted computer simulations of the performance of photovoltaic solar energy systems in order to size system components, to define designs of potential economic feasibility, to test various control schemes, and to monitor the performance of working systems in the field. When used as an aid-to-design, these hourly simulations step through a full year's worth of insolation and weather data at a specific geographical site. These data are available on computer tapes in the SOLMET format from the National Climatic Center. More recently, a simulation technique has been developed that does not require marching through time but instead works with probability-density functions of daily values of insolation and load as inputs while still providing estimates of the usual measures of system performance (e.g., auxiliary energy required, surplus energy thrown away, fraction of load displaced). Results obtained compare well with results previously obtained from an hourly simulation of a daytime radio station. This technique may be used to study the effect on system performance of varying degrees of correlation of load with insolation and to test the sensitivity of economic analyses to variations in utility escalation rate (discounted for inflation), PV module and balance-of-system costs.

FTIR Laboratory in Support of the PV Program  

SciTech Connect (OSTI)

The Fourier Transform Infrared Spectroscopy (FTIR) Laboratory supports the Solar Energy Technologies Program through the measurement and characterization of solar energy-related materials and devices. The FTIR technique is a fast, accurate, and reliable method for studying molecular structure and composition. This ability to identify atomic species and their bonding environment is a powerful combination that finds use in many research and development efforts. A brief overview of the technical approach used is contained in Section 2 of this report. Because of its versatility and accessibility, the FTIR Laboratory is a valuable contributor to the Solar Energy Technologies Program. The laboratory provides support for, and collaborates with, several in-house programs as well as our industry and university partners. By the end of FY 2004, the FTIR Laboratory performed over 1100 measurements on PV-related materials. These contributions resulted in conference and workshop presentations and several peer-reviewed publications. A brief summary of a few of these efforts is contained in Section 3 of this report.

Barbose, and Ryan H. Wiser Secondary Title Case Studies of State Support for Renewable Energy Publisher LBNL Place Published Berkeley Pagination 12 Date Published 11/2008 Abstract In early 2006, Berkeley Lab published an LBNL/CESA case study that examined the financial impact of EPAct 2005's solar tax credits on PV system owners, in light of the $2,000 cap on the residential credit, as well as the fact that most PV systems in the U.S. also receive cash incentives from state-, local-, or utility-administered PV programs, and that these cash incentives may reduce the value of federal tax credits in certain situations. That case study was subsequently revised in February 2007 to reflect new Internal Revenue Service (IRS) guidance. The findings of that case study, which are briefly recapped in the next section, remained relevant up until October 2008, when the Energy Improvement and Extension Act of 2008 extended both solar credits for an unprecedented eight years, removed the $2,000 cap on the residential credit, and eliminated restrictions on the use of both credits in conjunction with the Alternative Minimum Tax (AMT). These significant changes, which apply to systems placed in service on or after January 1, 2009, will increase the value of the solar credits for residential system owners in particular, and are likely to spur significant growth in residential, commercial, and utility-scale PV installations in the years ahead. In light of these substantial changes to the solar ITC, this report takes a fresh look at the value of these revised credits, focusing specifically on the Section 25D residential credit. After first setting the stage by briefly reviewing our previous findings, the document proceeds to cover four specific areas in which the removal of the $2,000 cap on the residential ITC will have significant implications for PV program administrators, PV system owners, and the PV industry that go beyond the obvious market growth potential created by these more-lucrative federal incentives. These four areas include:

Global prospects, progress, policies, and environmental impact of solar photovoltaic power generation  

Science Journals Connector (OSTI)

Abstract Global energy demand and environmental concerns are the driving force for use of alternative, sustainable, and clean energy sources. Solar energy is the inexhaustible and CO2-emission-free energy source worldwide. The Sun provides 1.4105TW power as received on the surface of the Earth and about 3.6104TW of this power is usable. In 2012, world power consumption was 17TW, which is less than 3.6104TW. Photovoltaic (PV) cells are the basic element for converting solar energy into electricity. PV cell technologies, energy conversion efficiency, economic analysis, energy policies, environmental impact, various applications, prospects, and progress have been comprehensively reviewed and presented in this paper. This work compiles the latest literature (i.e. journal articles, conference proceedings, and reports, among others) on PV power generation, economic analysis, environmental impact, and policies to increase public awareness. From the review, it was found that PV is an easy way to capture solar energy where PV based power generation has also rapidly increased.

BEopt-CA (Ex): A Tool for Optimal Integration of EE, DR and PV in Existing California Homes  

SciTech Connect (OSTI)

Opportunities for combining energy efficiency, demand response, and energy storage with PV are often missed, because the required knowledge and expertise for these different technologies exist in separate organizations or individuals. Furthermore, there is a lack of quantitative tools to optimize energy efficiency, demand response and energy storage with PV, especially for existing buildings. As technology costs evolve (e.g., the ongoing reduction in the cost of PV), design strategies need to be adjusted accordingly based on quantitative analysis.

Ota City : characterizing output variability from 553 homes with residential PV systems on a distribution feeder.  

SciTech Connect (OSTI)

This report describes in-depth analysis of photovoltaic (PV) output variability in a high-penetration residential PV installation in the Pal Town neighborhood of Ota City, Japan. Pal Town is a unique test bed of high-penetration PV deployment. A total of 553 homes (approximately 80% of the neighborhood) have grid-connected PV totaling over 2 MW, and all are on a common distribution line. Power output at each house and irradiance at several locations were measured once per second in 2006 and 2007. Analysis of the Ota City data allowed for detailed characterization of distributed PV output variability and a better understanding of how variability scales spatially and temporally. For a highly variable test day, extreme power ramp rates (defined as the 99th percentile) were found to initially decrease with an increase in the number of houses at all timescales, but the reduction became negligible after a certain number of houses. Wavelet analysis resolved the variability reduction due to geographic diversity at various timescales, and the effect of geographic smoothing was found to be much more significant at shorter timescales.

Progress of the PV Technology Incubator Project Towards an Enhanced U.S. Manufacturing Base  

SciTech Connect (OSTI)

In this paper, we report on the major accomplishments of the U.S. Department of Energy's (DOE) Solar Energy Technologies Program (SETP) Photovoltaic (PV) Technology Incubator project. The Incubator project facilitates a company's transition from developing a solar cell or PV module prototype to pilot- and large-scale U.S. manufacturing. The project targets small businesses that have demonstrated proof-of-concept devices or processes in the laboratory. Their success supports U.S. Secretary of Energy Steven Chu's SunShot Initiative, which seeks to achieve PV technologies that are cost-competitive without subsidies at large scale with fossil-based energy sources by the end of this decade. The Incubator Project has enhanced U.S. PV manufacturing capacity and created more than 1200 clean energy jobs, resulting in an increase in American economic competitiveness. The investment raised to date by these PV Incubator companies as a result of DOE's $ 59 million investment total nearly $ 1.3 billion.

Capacity Value of PV and Wind Generation in the NV Energy System  

SciTech Connect (OSTI)

Calculation of photovoltaic (PV) and wind power capacity values is important for estimating additional load that can be served by new PV or wind installations in the electrical power system. It also is the basis for assigning capacity credit payments in systems with markets. Because of variability in solar and wind resources, PV and wind generation contribute to power system resource adequacy differently from conventional generation. Many different approaches to calculating PV and wind generation capacity values have been used by utilities and transmission operators. Using the NV Energy system as a study case, this report applies peak-period capacity factor (PPCF) and effective load carrying capability (ELCC) methods to calculate capacity values for renewable energy sources. We show the connection between the PPCF and ELCC methods in the process of deriving a simplified approach that approximates the ELCC method. This simplified approach does not require generation fleet data and provides the theoretical basis for a quick check on capacity value results of PV and wind generation. The diminishing return of capacity benefit as renewable generation increases is conveniently explained using the simplified capacity value approach.

Installation of PV systems in GreeceReliability improvement in the transmission and distribution system  

Science Journals Connector (OSTI)

Photovoltaic (PV) power systems are becoming one of the most developing investment areas in the field of Renewable Energy Sources (RES). A statement of the status quo of PV power systems in Greece, and their contribution towards the improvement of power system reliability, is the scope of the present paper. Siting and installation of PV power systems is performed according to a recent Greek law, along with environmental and geographical constraints. Meteorological data are computed, formulated and imported to appropriate software in order to simulate the PV units and generate their power output. Data for unserved loads, resulting from load shedding during peak hours, are compared to the above estimated power production. Assuming that a proportion of the eventually unsupplied power could be provided by the accessed power generation of the PV units, the reliability of both transmission and distribution system is improved. The impact on the transmission system is shown by an improvement of LOLP and LOEP indices, whereas peak shaving for the Interconnected Greek Transmission System (IGTS) is also illustrated. For the distribution system the impact is quantified using the distribution system reliability indices SAIDI, SAIFI, and CAIDI. Finally, the resulting improvement is also expressed in financial terms.

Estimating Rooftop Suitability for PV: A Review of Methods, Patents, and Validation Techniques  

SciTech Connect (OSTI)

A number of methods have been developed using remote sensing data to estimate rooftop area suitable for the installation of photovoltaics (PV) at various geospatial resolutions. This report reviews the literature and patents on methods for estimating rooftop-area appropriate for PV, including constant-value methods, manual selection methods, and GIS-based methods. This report also presents NREL's proposed method for estimating suitable rooftop area for PV using Light Detection and Ranging (LiDAR) data in conjunction with a GIS model to predict areas with appropriate slope, orientation, and sunlight. NREL's method is validated against solar installation data from New Jersey, Colorado, and California to compare modeled results to actual on-the-ground measurements.

Public Response to Residential Grid-Tied PV Systems in Colorado: A Qualitative Market Assessment  

SciTech Connect (OSTI)

The early adopters of residential grid-tied photovoltaics (PV) have complex motivations to pay today's costs, including altruistic, environmental, and financial reasons. Focused interviews were conducted with a self-selected purposive sample interested in purchasing 2-kW or 3-kW PV systems with an installed cost of $8,000 to $12,000. The sample tended to be men or married couples ranging in age from their early thirties to their mid-eighties; professionals, managers, or small business owners; relatively financially secure, with experience with energy efficiency and renewable energy. Product attributes they preferred were net metering, warranties, guarantees, utility financing, maintenance, an option to own or lease, a battery option, and an aesthetically pleasing system. Potential PV customers needed more information before making a purchase decision.

Efficient Power Converters for PV Arrays : Scalable Submodule Power Conversion for Utility-Scale Photovoltaics  

SciTech Connect (OSTI)

Solar ADEPT Project: SolarBridge is developing a new power conversion technique to improve the energy output of PV power plants. This new technique is specifically aimed at large plants where many solar panels are connected together. SolarBridge is correcting for the inefficiencies that occur when two solar panels that encounter different amounts of sun are connected together. In most conventional PV system, the weakest panel limits the energy production of the entire system. Thats because all of the energy collected by the PV system feeds into a single collection point where a central inverter then converts it into useable energy for the grid. SolarBridge has found a more efficient and cost-effective way to convert solar energy, correcting these power differences before they reach the grid.

ASSERT-PV 3.2: Advanced subchannel thermalhydraulics code for CANDU fuel bundles  

Science Journals Connector (OSTI)

Abstract Atomic Energy of Canada Limited (AECL) has developed the subchannel thermalhydraulics code ASSERT-PV for the Canadian nuclear industry. The most recent release version, ASSERT-PV 3.2 has enhanced phenomenon models for improved predictions of flow distribution, dryout power and CHF location, and post-dryout (PDO) sheath temperature in horizontal CANDU fuel bundles. The focus of the improvements is mainly on modeling considerations for the unique features of CANDU bundles such as horizontal flows, small pitch to diameter ratios, high mass fluxes, and mixed and irregular subchannel geometries, compared to PWR/BWR fuel assemblies. This paper provides a general introduction to ASSERT-PV 3.2, and describes the model changes or additions in the new version to improve predictions of flow distribution, dryout power and CHF location, and PDO sheath temperatures in CANDU fuel bundles.

On-grid PV implementation program. Phase I report, August 1994--January 1995  

SciTech Connect (OSTI)

Southern California Edison Company (Edison) is finalizing a Cooperative Agreement with the U.S. Department of Energy (DOE) to develop high value On-Grid applications for electricity from Photovoltaics (PV). Edison`s efforts are the result of Edison`s long-standing commitment to the pursuit of Renewable Energy. Edison has been a world leader in the development and use of PV. As the technology becomes more commercial, Edison has been actively seeking more applications for PV. After strenuous effort, Edison has now received approval to offer off-grid PV packages within its service territory. In addition, Edison has been very interested in finding high-value on-grid PV applications that may have the potential to become cost effective as PV applications increase and prices decline. Such high-value applications at Edison and other utilities will accelerate the price reductions, which in turn will increase the number of cost-effective applications, driving towards a market competitive with traditional sources of energy. Edison`s efforts build upon the work done by Pacific Gas & Electric (PG&E) at their Kerman substation, but goes much further than that effort. Edison submitted its original proposal to the DOE on June 30, 1993. A revised proposal was submitted on February 1, 1994, in response to a letter from the DOE`s Director of Solar Energy, Robert H. Annan. In a letter dated March 30, 1994, from Paul K. Kearns, Head of Contracting Activity for the DOE`s Golden Field Office, the DOE conditionally approved certain pre-award contract costs. The Cooperative Agreement with DOE was executed on August 16, 1994.

The Use of Triangular-Shaped PV Arrays to Better Blend into Historical Structures  

Broader source: Energy.gov [DOE]

When considering the installation of a solar PV array on a designated historical structure, placement of each solar panel requires extra attention to aesthetic considerations. If the solar array cannot be installed behind the structure or hidden on a roof plane that is not visible from the public street or sidewalk, it can sometimes be installed as an architectural feature that blends into the historical structure. One way to do this is to utilize triangular-shaped PV panels that conform with the buildings roof lines.

The Impact of Rate Design and Net Metering on the Bill Savings from Distributed PV for Residential Customers in California  

SciTech Connect (OSTI)

Net metering has become a widespread policy in the U.S. for supporting distributed photovoltaics (PV) adoption. Though specific design details vary, net metering allows customers with PV to reduce their electric bills by offsetting their consumption with PV generation, independent of the timing of the generation relative to consumption - in effect, compensating the PV generation at retail electricity rates (Rose et al. 2009). While net metering has played an important role in jump-starting the residential PV market in the U.S., challenges to net metering policies have emerged in a number of states and contexts, and alternative compensation methods are under consideration. Moreover, one inherent feature of net metering is that the value of the utility bill savings it provides to customers with PV depends heavily on the structure of the underlying retail electricity rate, as well as on the characteristics of the customer and PV system. Consequently, the value of net metering - and the impact of moving to alternative compensation mechanisms - can vary substantially from one customer to the next. For these reasons, it is important for policymakers and others that seek to support the development of distributed PV to understand both how the bill savings varies under net metering, and how the bill savings under net metering compares to other possible compensation mechanisms. To advance this understanding, we analyze the bill savings from PV for residential customers of California's two largest electric utilities, Pacific Gas and Electric (PG&E) and Southern California Edison (SCE). The analysis is based on hourly load data from a sample of 215 residential customers located in the service territories of the two utilities, matched with simulated hourly PV production for the same time period based on data from the nearest of 73 weather stations in the state.

Artificial neural network based models for forecasting electricity generation of grid connected solar PV power plant  

Science Journals Connector (OSTI)

This paper presents an artificial neural network (ANN) approach for forecasting the performance of electric energy generated output from a working 25-kWp grid connected solar PV system and a 100-kWp grid connected PV system installed at Minicoy Island of Union Territory of Lakshadweep Islands. The ANN interpolates among the solar PV generation output and relevant parameters such as solar radiation, module temperature and clearness index. In this study, three ANN models are implemented and validated with reasonable accuracy on real electric energy generation output data. The first model is univariate based on solar radiation and the output values. The second model is a multivariate model based on module temperature along with solar radiation. The third model is also a multivariate model based on module temperature, solar radiation and clearness index. A forecasting performance measure such as percentage root mean square error has been presented for each model. The second model, which gives the most accurate results, has been used in forecasting the generation output for another PV system with similar accuracy.

Science Journals Connector (OSTI)

This paper present a study of a single pass photovoltaic/thermal (PV/T) solar collector combined with honeycomb heat exchanger. A PV/T system is a combination of photovoltaic panel and solar thermal components in one integrated system. In order to enhance the performance of the system a honeycomb heat exchanger is installed horizontally into the channel located under the PV module. Air is used as the heat remover medium. The system is tested with and without the honeycomb at irradiance of 828 W/m2 and mass flow rate spanning from 0.02 kg/s to 0.13 kg/s. It is observed that the aluminum honeycomb is capable of enhancing the thermal efficiency of the system efficiently. At mass flow rate of 0.11 kg/s the thermal efficiency of the system without honeycomb is 27% and with honeycomb is 87 %. Throughout the range of the mass flow rate the electrical efficiency of the PV module improved by 0.1 %. The improved design is suitable to be further investigated as solar drying system and space heating.

Optimal sizing study of hybrid wind/PV/diesel power generation unit  

SciTech Connect (OSTI)

In this paper, a methodology of sizing optimization of a stand-alone hybrid wind/PV/diesel energy system is presented. This approach makes use of a deterministic algorithm to suggest, among a list of commercially available system devices, the optimal number and type of units ensuring that the total cost of the system is minimized while guaranteeing the availability of the energy. The collection of 6 months of data of wind speed, solar radiation and ambient temperature recorded for every hour of the day were used. The mathematical modeling of the main elements of the hybrid wind/PV/diesel system is exposed showing the more relevant sizing variables. A deterministic algorithm is used to minimize the total cost of the system while guaranteeing the satisfaction of the load demand. A comparison between the total cost of the hybrid wind/PV/diesel energy system with batteries and the hybrid wind/PV/diesel energy system without batteries is presented. The reached results demonstrate the practical utility of the used sizing methodology and show the influence of the battery storage on the total cost of the hybrid system. (author)

Analytical model for solar PV and CSP electricity costs: Present LCOE values and their future evolution  

Science Journals Connector (OSTI)

In this paper we first make a review of the past annual production of electricity and the cumulative installed capacity for photovoltaic (PV) and concentrating solar power (CSP) technologies. This together with the annual costs of PV modules and CSP systems allows us the determination of the experience curves and the corresponding learning rates. Then, we go over a rigorous exposition of the methodology employed for the calculation of the value of the levelized cost of electricity (LCOE) for PV and CSP. Based on this knowledge, we proceed to establish a mathematical model which yields closed-form analytical expressions for the present value of the LCOE, as well as its future evolution (20102050) based on the International Energy Agency roadmaps for the cumulative installed capacity. Next, we explain in detail how specific values are assigned to the twelve independent variables which enter the LCOE formula: solar resource, discount and learning rates, initial cost and lifetime of the system, operational and maintenance costs, etc. With all this background, and making use of a simple computer simulation program, we can generate the following: sensitivity analysis curves, graphs on the evolution of the LCOE in the period 20102050, and calculations of the years at which grid parities will be reached. These representations prove to be very useful in energy planning policies, like tariff-in schemes, tax exemptions, etc., and in making investment decisions, since they allow, for a given location, to directly compare the costs of PV vs CSP power generation technologies for the period 20102050. Among solar technologies, PV seems always more appropriate for areas located in middle to high latitudes of the Earth, while CSP systems, preferably with thermal storage incorporated, yield their best performance in arid areas located at relatively low latitudes.

Department of Energy funded agreements with SMUD and Navigant Consulting, SunPower, GridPoint, the National Renewable Energy Laboratory, and the California Energy Commission for this pilot demonstration project. Funding was $5,962,409.00. Cost share of $500,000 was also provided by the California Energy Commission. The project has strategic implications for SMUD, other utilities and the PV and energy-storage industries in business and resource planning, technology deployment and asset management. These implications include: -At this point, no dominant business models have emerged and the industry is open for new ideas. -Demonstrated two business models for using distributed PV and energy storage, and brainstormed several dozen more, each with different pros and cons for SMUD, its customers and the industry. -Energy storage can be used to manage high penetrations of PV and mitigate potential issues such as reverse power flow, voltage control violations, power quality issues, increased wear and tear on utility equipment, and system wide power supply issues. - Smart meters are another tool utilities can use to manage high penetrations of PV. The necessary equipment and protocols exist, and the next step is to determine how to integrate the functionality with utility programs and what level of utility control is required. - Time-of-use rates for the residential customers who hosted energy storage systems did not cause a significant change in energy usage patterns. However, the rates we used were not optimized for PV and energy storage. Opportunities exist for utilities to develop new structures.

Shaking Up the Residential PV Market: Implications of Recent Changes to the ITC  

SciTech Connect (OSTI)

On August 8, 2005, the Energy Policy Act of 2005 (EPAct 2005) increased the Section 48 investment tax credit (ITC) for commercial photovoltaic (PV) systems from 10% to 30% of the project's 'tax credit basis' (i.e., the dollar amount to which the ITC applies), and also created in Section 25D of the Internal Revenue Code a new 30% ITC (capped at $2,000) for residential solar systems. Both changes went into effect on January 1, 2006, for an initial period of two years, and in late 2006 both credits were extended 'as is' for an additional year (through 2008). In early 2006, Berkeley Lab published an LBNL/CESA case study that examined the financial impact of EPAct 2005's solar tax credits on PV system owners, in light of the $2,000 cap on the residential credit, as well as the fact that most PV systems in the U.S. also receive cash incentives from state-, local-, or utility-administered PV programs, and that these cash incentives may reduce the value of federal tax credits in certain situations. That case study was subsequently revised in February 2007 to reflect new Internal Revenue Service (IRS) guidance. The findings of that case study, which are briefly recapped in the next section, remained relevant up until October 2008, when the Energy Improvement and Extension Act of 2008 extended both solar credits for an unprecedented eight years, removed the $2,000 cap on the residential credit, and eliminated restrictions on the use of both credits in conjunction with the Alternative Minimum Tax (AMT). These significant changes, which apply to systems placed in service on or after January 1, 2009, will increase the value of the solar credits for residential system owners in particular, and are likely to spur significant growth in residential, commercial, and utility-scale PV installations in the years ahead. In light of these substantial changes to the solar ITC, this report takes a fresh look at the value of these revised credits, focusing specifically on the Section 25D residential credit. After first setting the stage by briefly reviewing our previous findings, the document proceeds to cover four specific areas in which the removal of the $2,000 cap on the residential ITC will have significant implications for PV program administrators, PV system owners, and the PV industry that go beyond the obvious market growth potential created by these more-lucrative federal incentives. These four areas include: (1) The financial implications of whether or not residential cash rebates are considered to be taxable income; (2) The role of low-interest loan programs and other forms of 'subsidized energy financing' under an uncapped ITC; (3) The degree to which taxable and nontaxable rebate levels might be reduced in response to the extra value provided by an uncapped ITC; and (4) The impact of an uncapped ITC on third-party financing and ownership models that are just beginning to emerge in the residential sector. The document concludes by highlighting a common thread that runs throughout: the need for PV program managers to understand whether or not their rebates are considered to be taxable income before they can react in an appropriate manner to the recent changes in federal solar policy and, if financing programs are offered, the need to understand whether the IRS considers these programs to be 'subsidized'. Finally, we note that this paper is based on current law; future legislative changes to the ITC could, of course, alter the conclusions reached here.

Property Tax Assessments as a Finance Vehicle for Residential PV Installations: Opportunities and Potential Limitations  

SciTech Connect (OSTI)

Readily accessible credit has often been cited as a necessary ingredient to open up the market for residential photovoltaic (PV) systems. Though financing does not reduce the high up-front cost of PV, by spreading that cost over some portion of the system's life, financing can certainly make PV systems more affordable. As a result, a number of states have, in the past, set up special residential loan programs targeting the installation of renewable energy systems and/or energy efficiency improvements, and often featuring low interest rates, longer terms, and no-hassle application requirements. Historically, these loan programs have met with mixed success (particularly for PV), for a variety of reasons, including: (1) historical lack of homeowner interest in PV, (2) lack of program awareness, (3) reduced appeal in a low-interest-rate environment, and (4) a tendency for early PV adopters to be wealthy, and not in need of financing. Although some of these barriers have begun to fade--most notably, homeowner interest in PV has grown in some states, particularly those that offer solar rebates--the passage of the Energy Policy Act of 2005 (EPAct 2005) introduced one additional roadblock to the success of low-interest PV loan programs: a residential solar investment tax credit (ITC), subject to the Federal government's 'anti-double-dipping' rules. Specifically, the residential solar ITC--equal to 30% of the system's tax basis, capped at $2000--will be reduced or offset if the system also benefits from what is known as 'subsidized energy financing', which is likely to include most government-sponsored low-interest loan programs. Within this context, it has been interesting to note the recent flurry of announcements from several U.S cities concerning a new type of PV financing program. Led by the City of Berkeley, California, these cities propose to offer their residents the ability to finance the installation of a PV system using increased property tax assessments, rather than a more-traditional credit vehicle, to recover both system and administrative costs. As discussed in more detail later, this seemingly innovative approach has a number of features that should appeal to PV owners, including: long-term, fixed-cost, attractive financing; loans that are tied to the tax capacity of the property rather than to the owner's credit standing; a repayment obligation that transfers along with the sale of the property; and a potential ability to deduct the repayment obligation from Federal taxable income, as part of the local property tax deduction. For these reasons, Berkeley's program--which was first announced on October 23, 2007--has received considerable nationwide attention in both the trade and general press. Since the announcement, cities from throughout California and the broader U.S. have expressed keen interest in the possibility of replicating this type of program. In California alone, the cities of Santa Cruz, Santa Monica, and Palm Desert are all reportedly considering similar programs, while the city of San Francisco has recently announced its own program, portions of which closely parallel Berkeley's approach. Berkeley's Proposed PV Program In addition, a bill (AB 811) that would authorize all cities (not just 'charter cities' like Berkeley) in California to create this type of program was approved by the California General Assembly on January 29, 2008 and passed on to the State Senate for consideration. That local governments from across California and the broader US are so genuinely excited about the prospect of supporting the installation of residential PV in their communities through this type of program is no doubt an interesting development. Given, however, the potential for such programs to negatively interact with the residential solar ITC, it is important to evaluate the financial attractiveness of this specific type of loan program, particularly in advance of any broader state- or nation-wide 'rollout'. This case study presents such an evaluation. Because Berkeley appears to have the most-well-developed proposa

The doping effect of Italian feed-in tariffs on the PV market  

Science Journals Connector (OSTI)

Abstract In less than six years, Italy has become one of the leading markets for PV power plants and one of the countries in the world with the largest number of installations and installed peak power. Such a quick and large growth is due to a series of feed-in tariff schemes that have been uncapped until 2012. As a matter of fact, any size or any number of PV power plants could be installed during a period of three years. Since the feed-in tariffs are not paid by national taxes but are charged on the electricity bills, Italian energy users are now due to pay each year a surcharge of 9billioneuros on their energy bills. This paper aims at discussing this development by highlighting the benefits but also some significant drawbacks that the application of uncontrolled feed-in tariffs has produced.

Exploitation of temporary water flow by hybrid PV-hydroelectric plant  

Science Journals Connector (OSTI)

The paper presents a new type of Renewable Energy Sources (RES) suitable for exploitation watercourse with periodical-temporary water flow. This innovative solution consist of Hydroelectric Plant (HEP) and solar Photovoltaic (PV) generator working together as one hybrid power plant, producing green energy with the same characteristics as classical hydroelectric plants. The main objective of this hybrid solution is achievement of optimal renewable energy production in order to increase the share of RES in an Electricity Power System (EPS). As a paradigm of such exploitation of RES, the example of HEP Zavrelje/Dubrovnik in Croatia was used, where it was ascertained that the proposed solution of hybrid PV-HEP system is natural, realistic and very acceptable, which enhances the characteristics of both energy sources. The application of such hybrid systems would increase the share of high quality RES in energy systems.

Battery and charge controller evaluations in small stand-alone PV systems  

SciTech Connect (OSTI)

We report the results of to separate long-term tests of batteries and charge controllers in small stand-alone PV systems. In these experiments, seven complete systems were tested for two years at each of two locations: Sandia National Laboratories in Albuquerque and the Florida Solar Energy Center in Cape Canaveral, Florida. Each system contained a PV array, flooded-lead-acid battery, a charge controller and a resistive load. Performance of the systems was strongly influenced by the difference in solar irradiance at the two sites, with some batteries at Sandia exceeding manufacturer`s predictions for cycle life. System performance was strongly correlated with regulation reconnect voltage (R{sup 2} correlation coefficient = 0.95) but only weakly correlated with regulation voltage. We will also discuss details of system performance, battery lifetime and battery water consumption.

Direct power control of grid connected PV systems with three level NPC inverter  

SciTech Connect (OSTI)

This paper presents the control of a three-level Neutral Point Clamped (NPC) voltage source inverter for grid connected photovoltaic (PV) systems. The control method used is the Extended Direct Power Control (EDPC), which is a generic approach for Direct Power Control (DPC) of multilevel inverters based on geometrical considerations. Maximum Power Point Tracking (MPPT) algorithms, that allow maximal power conversion into the grid, have been included. These methods are capable of extracting maximum power from each of the independent PV arrays connected to each DC link voltage level. The first one is a conventional MPPT which outputs DC link voltage references to EDPC. The second one is based on DPC concept. This new MPPT outputs power increment references to EDPC, thus avoiding the use of a DC link voltage regulator. The whole control system has been tested on a three-level NPC voltage source inverter connected to the grid and results confirm the validity of the method. (author)

SciTech Connect (OSTI)

The U.S. Environmental Protection Agency (EPA) Region 5, in accordance with the RE-Powering America's Land initiative, selected the Atlas Industrial Park in Duluth, Minnesota, for a feasibility study of renewable energy production. The EPA provided funding to the National Renewable Energy Laboratory (NREL) to support a feasibility study of solar renewable energy generation at the Atlas Industrial Park. NREL provided technical assistance for this project but did not assess environmental conditions at the site beyond those related to the performance of a photovoltaic (PV) system. The purpose of this study is to assess the site for a possible PV installation and estimate the cost, performance, and site impacts of different PV configurations. In addition, the study evaluates financing options that could assist in the implementation of a PV system at the site.

Measuring sin^2 theta_W in PV-DIS with the Baseline Spectrometers at JLab 12 GeV  

SciTech Connect (OSTI)

The couplings of leptons to quarks are fundamental parameters of the electroweak interaction. Within the framework of the Standard Model, these couplings can be related to sin2 theta W. Parity violation (PV) in deep inelastic scattering (DIS) is proportional to these couplings and hence sensitive sin2 theta W. PV-DIS, first measured at SLAC in the mid-1970s, was used to establish the Standard Model. The high quality and intensity of the upgraded 11 GeV CEBAF beam at Jefferson Laboratory will make it an ideal tool for PV studies. In DIS the asymmetry from parity violation is large (APV ~ 10^?4 Q^2), allowing precise measurements with modest beam-time. This talk will explore a PV-DIS measurement which can be made using the baseline spectrometers that will exist as part of the 12 GeV JLab upgrade.

Framework for a Comparative Accelerated Testing Standard for PV Modules: Preprint  

SciTech Connect (OSTI)

As the photovoltaic industry has grown, the interest in comparative accelerated testing has also grown. Private test labs offer testing services that apply greater stress than the standard qualification tests as tools for differentiating products and for gaining increased confidence in long-term PV investments. While the value of a single international standard for comparative accelerated testing is widely acknowledged, the development of a consensus is difficult. This paper strives to identify a technical basis for a comparative standard.
