  10. Advanced solar panel designs

    SciTech Connect

    Ralph, E.L.; Linder, E.

    1995-10-01

    This paper describes solar cell panel designs that utilize new high efficiency solar cells along with lightweight rigid panel technology. The resulting designs push the W/kg and W/sq m parameters to new high levels. These new designs are well suited to meet the demand for higher performance small satellites. This paper reports on progress made on two SBIR Phase 1 contracts. One panel design involved the use of large area (5.5 cm x 6.5 cm) GaAs/Ge solar cells of 19% efficiency combined with a lightweight rigid graphite fiber epoxy isogrid substrate configuration. A coupon (38 cm x 38 cm) was fabricated and tested which demonstrated an array specific power level of 60 W/kg with a potential of reaching 80 W/kg. The second panel design involved the use of newly developed high efficiency (22%) dual junction GaInP2/GaAs/Ge solar cells combined with an advanced lightweight rigid substrate using aluminum honeycomb core with high strength graphite fiber mesh facesheets. A coupon (38 cm x 38 cm) was fabricated and tested which demonstrated an array specific power of 105 W/kg and 230 W/sq m. This paper will address the construction details of the panels and an analysis of the component weights. A strawman array design suitable for a typical small-sat mission is described for each of the two panel design technologies being studied. Benefits in respect to weight reduction, area reduction, and system cost reduction are analyzed and compared to conventional arrays.

The mandrel is moved within the manifold tube so as to position the projecting elements through the side wall portion thereof and into the open ends of said corresponding panel structure passages and the manifold tube toward the panel structure end so as to cause the manifold tube side wall portion to apply a pressure to the panel structure end sufficient to deform the thermoplastic material thereof and effect a fusing of the same into a unitary mass. The mandrel is then withdrawn in the direction of extent of the projecting elements to a position within the interior of the manifold tube and then longitudinally out of the manifold tube and apparatus for carrying out the method.

  2. Concentrating Solar Panels: Bringing the Highest Power and Lowest Cost to the Rooftop

    SciTech Connect

    Michael Deck; Rick Russell

    2010-01-05

    Soliant Energy is a venture-capital-backed startup focused on bringing advanced concentrating solar panels to market. Our fundamental innovation is that we are the first company to develop a racking solar concentrator specifically for commercial rooftop applications, resulting in the lowest LCOE for rooftop electricity generation. Today, the commercial rooftop segment is the largest and fastest-growing market in the solar industry. Our concentrating panels can make a major contribution to the SAI's objectives: reducing the cost of solar electricity and rapidly deploying capacity. Our commercialization focus was re-shaped in 2009, shifting from an emphasis solely on panel efficiency to LCOE. Since the inception of the SAI program, LCOE has become the de facto standard for comparing commercial photovoltaic systems. While estimation and prediction models still differ, the emergence of performance-based incentive (PBI) and feed-in tariff (FIT) systems, as well as power purchase agreement (PPA) financing structures make LCOE the natural metric for photovoltaic systems. Soliant Energy has designed and demonstrated lower-cost, higher-power solar panels that consists of 6 (500X) PV module assemblies utilizing multi-junction cells and an integrated two-axis tracker. In addition, we have designed and demonstrated a prototype 1000X panel assembly with 8. Cost reductions relative to conventional flat panel PV systems were realized by (1) reducing the amount of costly semiconductor material and (2) developing strategies and processes to reduce the manufacturing costs of the entire system. Performance gains against conventional benchmarks were realized with (1) two-axis tracking and (2) higher-efficiency multi-junction PV cells capable of operating at a solar concentration ratio of 1000X (1000 kW/m2). The program objectives are: (1) Develop a tracking/concentrating solar module that has the same geometric form factor as a conventional flat, roof mounted photovoltaic (PV) panel

    1981-01-06

    The panel for converting solar energy to sensible heat of a working fluid comprises a thermally-insulated and impervious base member overlayed with and spaced from a solar-collecting member or collector. The collector is in turn overlayed with and spaced from a pair of mutually spaced impervious films which are essentially transparent to incident solar radiation and substantially opaque to radiation emitted by the collector. The solar-collecting member consists of a thermally-insulating porous matrix substance and of a second substance affixed thereto. The second substance is in divided and substantially discrete form. The second substance exhibits a high degree of absorptivity for solar radiation and low emissivity for long wave radiation. The working fluid to be heated is admitted to a chamber underneath the solar-collecting member. The working fluid has a pressure sufficient to cause it to percolate through the collector. The percolated fluid is collected between the collector and the first overlaying film. The panel assembly is formed by connecting the solar panels in series and/or parallel arrays which carry the working fluid and allow it to absorb the desired quantity of heat.

    SciTech Connect

    Baker, R.H.

    1983-03-01

    The D.C. Power supplied by a photovoltaic solar panel to a load is controlled by monitoring the slope of the panel voltage vs. Current characteristic and adjusting the current supplied by the panel to the load so that the slope is approximately unity. The slope is monitored by incrementally changing the panel load and indicating whether the resulting change in current derived from the panel is above or below a reference value, indicative of the panel voltage. In response to the change in the monitored current being above the reference value, the slope of a voltage vs. Current curve is greater than unity and the load is adjusted to decrease the current supplied by the panel to the load. Conversely, in response to the current being less than the reference value, the slope of the voltage vs. Current curve is less than unity and the load is adjusted to increase the current supplied by the panel to the load.

    SciTech Connect

    Anderson, R.M.; Barnard, R.W.; Ford, W.T.

    1986-03-15

    This study is concerned with designing mirror panel layouts for a spherical shaped solar bowl. It was carried out as part of the Crosbyton Solar Power Project (CSPP). The CSPP is concerned with the development of a technology for producing electric power from steam generated by reflection of the sun's rays from a fixed mirror solar bowl onto a tracking receiver. In this system, the receiver is cantilevered and pivots about the center of curvature of the mirror. This study describes mathematical techniques for designing the mirror surface. The method is based on an icosahedral breakdown of the surface of a sphere and the resulting bowl is called an icosahedral bowl. As an example, a sixty degree icosahedral bowl is constructed from two sets of fifteen identical spherical triangles. These thirty spherical triangles are called superpanels and are used to support several smaller mirrors. The small mirrors used to cover the surface of the icosahedral bowl are hexagonal in shape. This shape mirror gives extremely good coverage of the bowl surface and minimizes parameters such as total mirror perimeter and gap area between mirrors. In addition, this choice of mirror shape yields the same mirror panel layout on each superpanel.

  15. Concentrating Solar Power Central Receiver Panel Component Fabrication and Testing FINAL REPORT

    SciTech Connect

    McDowell, Michael W; Miner, Kris

    2013-03-30

    The objective of this project is to complete a design of an advanced concentrated solar panel and demonstrate the manufacturability of key components. Then confirm the operation of the key components under prototypic solar flux conditions. This work is an important step in reducing the levelized cost of energy (LCOE) from a central receiver solar power plant. The key technical risk to building larger power towers is building the larger receiver systems. Therefore, this proposed technology project includes the design of an advanced molten salt prototypic sub-scale receiver panel that can be utilized into a large receiver system. Then complete the fabrication and testing of key components of the receive design that will be used to validate the design. This project shall have a significant impact on solar thermal power plant design. Receiver panels of suitable size for utility scale plants are a key element to a solar power tower plant. Many subtle and complex manufacturing processes are involved in producing a reliable, robust receiver panel. Given the substantial size difference between receiver panels manufactured in the past and those needed for large plant designs, the manufacture and demonstration on prototype receiver panel components with representative features of a full-sized panel will be important to improving the build process for commercial success. Given the thermal flux limitations of the test facility, the panel components cannot be rendered full size. Significance changes occurred in the projects technical strategies from project initiation to the accomplishments described herein. The initial strategy was to define cost improvements for the receiver, design and build a scale prototype receiver and test, on sun, with a molten salt heat transport system. DOE had committed to constructing a molten salt heat transport loop to support receiver testing at the top of the NSTTF tower. Because of funding constraints this did not happen.

  17. Technical evaluation of a solar heating system having conventional hydronic solar collectors and a radiant panel slab. Final report

    SciTech Connect

    Starr, R.J.

    1984-04-01

    A simple innovative solar heating design (Solar Option One) using conventional hydronic solar collectors and a radiant panel slab was constructed. An objective of hybrid solar design is to combine the relative advantages of active and passive design approaches while minimizing their respective disadvantages. A test house using the Solar Option One heating system was experimentally monitored to determine its energy based performance during the 1982-83 heating season. The test residence is located in Lyndonville, Vermont, an area which has a characteristically cold and cloudy climate. The two story residence has a floor area of about 1400 square feet and is constructed on a 720 square foot 5.5 inch thick floor slab. A 24 inch packed gravel bed is located beneath the slab and the slab-gravel bed is insulated by two inches of polystyrene insulation. The test building is of frame construction and uses insulation levels which have become commonplace throughout the country. The structure would not fall into the superinsulated category but was tightly constructed so as to have a low infiltration level. The building is sun-tempered in that windows were concentrated somewhat on the South side and all but avoided on the North. A solar greenhouse on the South side of the building was closed off from the structure permanently throughout the testing so as to better observe the solar heating invention without confounding variables. The monitoring equipment generated an internal gain of about 17,000 BTUs per day, roughly the equivalent of occupancy by two persons. A full description of the experimental testing program is given. System efficiency and performance are reported.

    This report will detail substantial improvements in each of the task areas. A number of new products were developed, including a 130 kW array built using a new panel design. Improvements in laboratory-scale solar cell processing resulted in a confirmed efficiency of 16.6%. A new Silicon-Film{trademark} production sheet machine was built which increased throughput by 70%. Three solar cell fabrication processes were converted from low throughout batch processes to high throughput, continuous, belt processes. These new processes are capable of processing sheet over 31 cm in width. Finally, a new Silicon-Film{trademark} sheet machine was built that demonstrated a sheet width of 38 cm. This tool enabled AstroPower to demonstrate a wide range of solar cell sizes, many of which have generated considerable market interest.

    1981-07-01

    One part of the evaluation program for a molten sodium central receiver was to be a test of a reduced-scale panel at Sandia's Central Receiver Test Facility in Albuquerque. The panel incorporates a new way of joining tubes - brazing to intermediate filler strips - which can affect the panel's lifetime. To calculate the stresses and strains for the worst-case section of the experimental panel, we have done a nonlinear elastic-plastic analysis with the MARC finite element computer code, which takes the temperature dependence of the material properties into account. From the results, tube design lifetimes are predicted. The analysis shows that concerns for cracking and reduction in lifetime are warranted, but a more detailed fracture analysis is necessary to determine whether there is a stable-crack-growth problem.

  8. Real Time Selective Harmonic Minimization for Multilevel Inverters Connected to Solar Panels Using Artificial Neural Network Angle Generation

    SciTech Connect

    Tolbert, Leon M; Ozpineci, Burak; Filho, Faete; Cao, Yue

    2011-01-01

    This work approximates the selective harmonic elimination problem using artificial neural networks (ANNs) to generate the switching angles in an 11-level full-bridge cascade inverter powered by five varying dc input sources. Each of the five full bridges of the cascade inverter was connected to a separate 195-W solar panel. The angles were chosen such that the fundamental was kept constant and the low-order harmonics were minimized or eliminated. A nondeterministic method is used to solve the system for the angles and to obtain the data set for the ANN training. The method also provides a set of acceptable solutions in the space where solutions do not exist by analytical methods. The trained ANN is a suitable tool that brings a small generalization effect on the angles' precision and is able to perform in real time (50-/60-Hz time window).

    AstroPower is establishing a low cost manufacturing process for Silicon-Film{trademark} solar cells and panels by taking advantage of the continuous nature of the Silicon-Film{trademark} technology. Under this effort, each step used in Silicon-Film{trademark} panel fabrication is being developed into a continuous/in-line manufacturing process. The following benefits are expected: an accelerated reduction of PV manufacturing cost for installed systems; a foundation for significantly increased production capacity; and a reduction in handling and waste streams. The process development will be based on a new 31-cm wide continuous Silicon-Film{trademark} sheet. Long-term goals include the development of a 24W, 30 cm x 60 cm Silicon-Film{trademark} solar cell and a manufacturing capability for a 384W, 4 inches x 8 inches Silicon-Film{trademark} panel for deployment in utility-scale applications.

  12. Absorptivity of semiconductors used in the production of solar cell panels

    2012-04-15

    The dependence of the absorptivity of semiconductors on the thickness of the absorbing layer is studied for crystalline silicon (c-Si), amorphous silicon (a-Si), cadmium telluride (CdTe), copper indium diselenide (CuInSe{sub 2}, CIS), and copper gallium diselenide (CuGaSe{sub 2}, CGS). The calculations are performed with consideration for the spectral distribution of AM1.5 standard solar radiation and the absorption coefficients of the materials. It is shown that, in the region of wavelengths {lambda} = {lambda}{sub g} = hc/E{sub g}, almost total absorption of the photons in AM1.5 solar radiation is attained in c-Si at the thickness d = 7-8 mm, in a-Si at d = 30-60 {mu}m, in CdTe at d = 20-30 {mu}m, and in CIS and CGS at d = 3-4 {mu}m. The results differ from previously reported data for these materials (especially for c-Si). In previous publications, the thickness needed for the semiconductor to absorb solar radiation completely was identified with the effective light penetration depth at a certain wavelength in the region of fundamental absorption for the semiconductor.

    1983-11-01

    The objectives of the assessment were to identify: research needs by topic and activity, relative priority of research needs, options for performing needed research, potential performers, costs and duration of R and D activities, gaps and duplications within the R and D program, and activities underway that appear to be of low priority. To achieve these objectives, research programs of the Division of Solar Thermal Technologies within the Office of Renewable Energy and Conservation and the Materials and Advanced Energy Programs of the Office of Basic Energy Sciences were reviewed. Several recent assessments of solar thermal research needs made within the past two years by various groups were also reviewed, and the key research issues and needs were extracted. The primary results from the assessment are a set of prioritized activities to meet the most important research needs for solar thermal technologies. These activities belong to four disciplines: materials science, thermal science, thermochemistry, and engineering. Further, priorities associated with the needs for research result from the various activities allow the recommended activities to be grouped into two categories; a core group which should be at the heart of any future program developed by the department, and a set of important needs that should, at least, find their way into a program at some time during its existence. The recommended research program is outlined, and the complete set of ranked research needs is listed.

  14. Pitting and crevice corrosion potentials of solar panel stainless steels in seawater and 0. 6M NaCl

    1985-03-01

    The cyclic potentiokinetic polarization method (scanning rate 10 mV/min), starting at the free corrosion potential and going up to 100 ..mu..A/cm/sup 2/ (surface area), and microscopic observation o the surface were used to evaluate the susceptibility of commercial stainless steels to localized corrosion for their possible application in solar panels. Aerated and deaerated solutions of 0.6M NaCl and seawater at room temperature were used. Considering the average value of the pitting potential obtained in numerous tests, the following stability classification was established for the materials studied: 430 < 430 Nb < 304 < 304L < ELI (C) less than or equal to 316 < ELI (D) The appearance of morphological differences in pits on the same material and the presence of cavernous pits, detectable after light abrasion of the surface or in a cross section of the sample made their quantification and a determination of any definite relation between surface defects (segregations and/or microflaws) and passive film breakdown susceptibility very difficult. Crevice corrosion could occur under free corrosion conditions, especially in the presence of air, and it was detectable from potential oscillations. The crevice potential is not estimated with the same technique used to determine pitting potential because of the strong effect of the critical shield geometry; it is therefore suggested that the redox couple K/sub 4/Fe(CN)/sub 6/ - K/sub 3/Fe(CN)/sub 6/, in suitable concentration in the system being considered, can give useful indications of this potential. Indeed, the rapid precipitation of Turnbull's blue physically prevents the repassivation process at the electrode potential established by the redox couple.

    The Silicon-Film{trademark} process is on an accelerated path to large-scale manufacturing. A key element in that development is optimizing the specific geometry of both the Silicon-Film{trademark} sheet and the resulting solar cell. That decision has been influenced by cost factors, engineering concerns, and marketing issues. The geometry investigation has focused first on sheet nominally 15 cm wide. This sheet generated solar cells with areas of 240 cm{sup 2} and 675 cm{sup 2}. Most recently, a new sheet fabrication machine was constructed that produces Silicon-Film{trademark} with a width in excess of 30 cm. Test results have indicated that there is no limit to the width of sheet generated by this process. The new wide material has led to prototype solar cells with areas of 300, 400, and 1,800 cm{sup 2}. Significant advances in solar-cell processing have been developed in support of fabricating large-area devices, including uniform emitter diffusion and anti-reflection coatings.

    A solar reflector system is described for reflecting solar energy to an elongated solar receiving area disposed generally in an east-west direction and for helping to optimize the performance versus cost ratios of concentrating solar collector systems utilizing the solar reflector system. The solar reflector system consists of an elongated side reflector panel means to be hinged relative to the solar receiving area, hinge means adjacent the solar receiving area for pivotally connecting the reflector panel means relative to the solar receiving area. The reflector panel means include a reflector surface comprised of a plurality of flat planar reflector panels that are each elongated parallel to the solar receiving area for about the length of the solar receiving area, with adjacent flat planar reflector panels comprising the reflector surface sharing a common edge that extends parallel to the solar receiving area and forming an angle appropriate to facilitate efficient performance of the overall reflector panel means in reflecting solar energy to the solar receiving area, means for adjusting one, some, or all of the angles formed by adjacent flat planar reflector panels comprising the reflector surface. The curvature of the overall reflector surface may be altered on a seasonal basis, and means for adjusting the entire reflector panel means relative to the solar receiving area about the hinge means, so as to improve year-round reflector panel means performance in reflecting solar energy to the solar receiving area.

    Solar is one of the most easily exploitable energy, it is moreover inexhaustible. His applications are many and are varied. The heating of the domestic water is one of the most immediate, simplest and also of most widespread exploitation of the solar energy. Algeria, from its geographical situation, it deposits one of the largest high sun surface expositions in the world. The exposition duration of the almost territory exceeds 2000 hours annually and can reach the 3900 hours (high plateaus and Sahara). By knowing the daily energy received by 1 m{sup 2} of a horizontal surface of the solar thermal panel is nearly around 1700 KWh/m{sup 2} a year in the north and 2263 KWh/m{sup 2} a year in the south of the country, we release the most important and strategic place of the solar technologies in the present and in the future for Algeria. This work consists to study, conceive and manufacture solar water heating with the available local materials so, this type of the energy will be profitable for all, particularly the poor countries. If we consider the illumination duration of the panel around 6 hours a day, the water heat panel manufactured in our laboratory produce an equivalent energy of 11.615 KWh a day so, 4239 KWh a year. These values of energy can be easily increased with performing the panel manufacture.

    SciTech Connect

    Brindle, D.K.; Shanfelt, D.Y.

    1980-01-08

    An inflatable solar energy collector utilizes flexible materials and is adapted to be inflated by a flow of pressurized gas therethrough. Inflation positions a solar energy collecting panel at an appropriate predetermined angle for effectively collecting solar energy. The solar collector includes an enclosure defining a generally tubular configuration, and the energy collecting panel extends in a planar and chord-like manner through the interior of the enclosure. Wall portions of the enclosure comprise solar radiation transparent material to allow incident solar radiation to pass therethrough onto the energy collecting panel. A second panel of solar radiation transparent material is operatively sealed to the energy collecting panel in selected positions to define a gas conducting conduit extending over the energy collecting panel. A flow of pressurized gas is conducted into the gas conducting conduit and removes the solar radiation absorbed by the energy collecting panel in the form of heat. Means conducts pressurized gas from the gas conducting conduit into the interior of the enclosure for inflating the collector and positioning the energy collecting panel at the optimum angle for absorbing incident solar radiation. Attaching means are positioned at the exterior of the enclosure for selectively attaching the enclosure to a support surface in a desired manner whereby the energy collecting panel is optimally angled upon inflation of the collector.

    A common misconception about solar photovoltaic (PV) panels is that they inherently cause or create "too much" glare, posing a nuisance to neighbors and a safety risk for pilots. While solar PV systems can produce glare, light absorption - rather than reflection - is central to the function of solar PV panels. This fact sheet describes the basic issues surrounding glare from solar PV panels, the new Federal Aviation Administration guidance, and the implications for local governments.

    2012-03-01

    This fact sheet highlights the energy challenges faced by the Virgin Islands Environmental Resource Station (VIERS), the renewable energy and energy efficiency solutions implemented, the resulting energy efficiency savings, and other project benefits. In 2011, VIERS installed a 9.4 kW solar system funded by a $50,000 American Recovery and Reinvestment Act (ARRA) grant, which was administered by VIEO. To identify additional energy-saving opportunities, VIERS performed an energy audit of appliances, which resulted in the removal of two water coolers and the installation of a water meter to monitor water use and how it relates to electric pump use. VIERS also added an educational component to the project, developing a solar classroom near the original solar system. By building on previous energy conservation measures and making additional investments in renewable energy technology, VIERS has lowered its average monthly energy consumption nearly 30%, even with an increase in guests. The VIERS efforts are not limited to the technology installations, however. They also serve to impact the youth of the U.S. Virgin Islands (USVI) by educating young people about energy efficiency and renewable energy technologies and their energy and environmental impacts. VIERS solar system is connected to the Web via a live feed that posts solar output data in real time, increasing the VIERS solar classroom's potential educational impact exponentially.

    1985-01-01

    A solar collector having a copper panel in a contiguous space relationship with a condenser-evaporator heat exchanger located under the panel, the panel having a honeycomb-like structure on its interior defining individual cells which are filled with zeolite loaded, in its adsorbed condition, with 18 to 20% by weight of water. The interior of the panel and heat exchanger are maintained at subatmospheric pressure of about 0.1 to 1 psia. The panel and heat exchanger are insulated on their lateral sides and bottoms and on the top of the heat exchange. The panel has a black coating on its top which is exposed to and absorbs solar energy. Surrounding the insulation (which supports the panel) is an extruded aluminum framework which supports a pair of spaced-apart glass panels above the solar panel. Water in conduits from a system for heating or cooling or both is connected to flow into an inlet and discharge from outlet of a finned coil received within the heat exchanger. The collector panel provides heat during the day through desorption and condensing of water vapor from the heated solar panel in the heat exchanger and cools at night by the re-adsorption of the water vapor from the heat exchanger which lowers the absolute pressure within the system and cools the heat exchange coils by evaporation.

    1981-01-06

    A supply of hollow plastic tubing is obtained from an extrusion and sizing apparatus, or from a supply of hollow tubing on a reel. The hollow tubing is provided at a predetermined speed to a tensioning device which imparts a tension in the hollow tubing and delivers it to a feeding point at one edge of the periphery of a rotating drum. The continuous hollow tubing is wound around the periphery of the drum at the one edge and it is forced axially on the periphery by a helical shoe overlying the periphery at the one edge. A bank of quartz lamps heats one side of the hollow plastic tubing just prior to reaching the feeding point, and another bank of quartz lamps heats the opposite side of the hollow plastic tubing at the one edge of the drum just after the tubing passes the shoe. The two heated surfaces are pressed together by the axial force exerted by the shoe, and are fused in side by side relation to form a cylinder having a wall consisting of spiral turns of the plastic tubing fused together.

    One of the most effective methods of utilizing solar energy is to use the sunlight and solar thermal energy such as a photovoltaic-thermal panel (PV/T panel) simultaneously. From such a viewpoint, systems using various kinds of PV panels were constructed in the world. In these panels, solar cells are set up at an absorber collecting solar thermal energy. Therefore, temperature of solar cell increases up to the prescribed temperature of thermal energy use, although it is lower than the cell temperature when using only solar cell panel. For maintaining cell conversion efficiency at the standard conditions, it is necessary to keep the cell at lower temperature. In this paper, electric and thermal energy obtained form a PV/T panel is evaluated in terms of energy. BAsed on this evaluation, the method of not to decrease cell conversion efficiency with collecting solar thermal energy was proposed.

    Energy.gov [DOE]

    A public-private partnership has helped one Air Force base reduce its energy costs and convert to 25 percent renewable energy. Nellis Air Force Base, just north of Las Vegas, took a big step in 2007 when it installed a 14.2-megawatt, 70,000-panel photovoltaic solar array that reduced carbon dioxide emissions by 24,000 tons a year. Built partly on a landfill, the field of solar panels takes advantage of two resources plentiful in Nevada: sunshine and empty land. At its unveiling in December of 2007, the Nellis array was the largest solar panel installation in North America. The project was originally expected to produce about 30,000 megawatt-hours of electricity per year, but Steven Dumont, Air Combat Command Energy Manager, says it’s actually producing closer to 32,000 megawatt-hours, which is about 8 percent above expectations. Despite this success, Dumont said he nearly didn’t pursue the project.

    An oven roof or wall is formed from modular panels, each of which comprises an inner fabric and an outer fabric. Each such fabric is formed with an angle iron framework and somewhat resilient tie-bars or welded at their ends to flanges of the angle irons to maintain the inner and outer frameworks in spaced disposition while minimizing heat transfer by conduction and permitting some degree of relative movement on expansion and contraction of the module components. Suitable thermal insulation is provided within the module. Panels or skins are secured to the fabric frameworks and each such skin is secured to a framework and projects laterally so as slidingly to overlie the adjacent frame member of an adjacent panel in turn to permit relative movement during expansion and contraction.

    A load-bearing building panel capable of forming an external wall cladding or roof component has a solar heat collecting capacity in the form of channels for heat exchange fluid incorporated in the fabric of the panel. The panel is made of a structural plastics material, such as GRP. Laminate, successive layers being moulded to simulate tiles. On the back or underside, longitudinal reinforcing beams are built in during laying up of the panel. Between the beams cores or formers defining a matrix or channels are encapsulated in layers of the GRP. Wax cores are melted or dissolved out after curing of the panel; metal formers remain embedded in the fabric of the panel. The matrix is connected by flow and return pipes to a heat exchange system within the building. Panels intended for roofing have ridge flanges and wall plates moulded into the substrate at the appropriate pitch angle, and a split capping tube embraces the ridge flanges. A pitched roof formed by oppositely sloping panels is self-supporting. An integral box girder can also be formed across the underside of the panel at the eaves to rest on the top of the external wall to be loaded with concrete in situ so as to anchor the roof on the walls.

  3. Rooftop Solar PV & Firefighter Safety

    Energy.gov [DOE]

    Solar photovoltaic (PV) installations have experienced significant growth in recent years. Due to technological innovations and cost reductions, solar energy is a viable option for an increasing number of residences and businesses across the United States. Rooftop solar is considered safe – to date there has been no documented case of death from the electric shock, chemical burn or conventional fire caused by a solar panel; however, as more buildings install rooftop solar systems, the likelihood increases that fires will occur on buildings with solar, making it critical for firefighters to receive comprehensive solar education and training. This SolarOPs fact sheet gives a brief overview of typical solar PV installations, addresses the major hazards and risks to firefighters, discusses fire safety in Germany (the country with the most installed solar PV per capita), and suggests recommendations and resources to ensure that first responders are prepared to fight fires on homes and buildings with rooftop solar PV.

Approximately 60 invited panelists and 120 observers met in three panels devoted to Solar Energy and Cities and three panels on Solar Energy and Employment. The day-and-one-half meeting occurred at the Department of Energy's Forrestal Building headquarters in Washington, DC, on 23 and 24 October 1979. Introductory speeches by seven experts, excerpts from the succeeding two half-days of discussion, the final reports for the panel chairpersons, and subsequent discussion and questioning are included. Approximately 125 findings and recommendations were developed by the six panels covering a wide variety of topics. Major recurring themes were recommendations for increased funding, federal program improvement, conservation, outreach programs, small business funding, and solar training programs. Detailed responses from the Department of Energy have been prepared for all recommendations and are contained in a companion volume.

    Buying a solar energy system will likely increase your home’s value. A recent study found that solar panels are viewed as upgrades, just like a renovated kitchen or a finished basement, and home buyers across the country have been willing to pay a premium of about $15,000 for a home with an average-sized solar array. Additionally, there is evidence homes with solar panels sell faster than those without.

    A combined table and portable solar water heater comprises a suitcase-like rigid casing molded from a rigid plastic material which contains a pair of solar collector panels and connected in series. The panels can be exposed to solar radiation when the casing is opened. Each collector panel or is formed by a copper plate with the solar radiation absorbing surface and copper pipe coil or in heat-transferring relationship with said copper plate. The casing is provided with compartments for accessories, such as adjustable legs for supporting the casing, adjusting its angle to incident sunlight, and for converting the casing into a table; containers for feeding cold water to the solar collector and for receiving hot water from the collector; and a tripod stand for supporting the feeding container at the level above the collector and for arranging a shower set. Temperature-insulating layers of the collectors are formed by separate pieces of rigid material which can be removed from the casing and assembled into a box-shaped container which can be utilized for maintaining water heated by means of the solar water heater at an elevated temperature.

  7. Control design deficiencies in HUD solar demonstration projects

    SciTech Connect

    Freeborne, W.E.

    1985-01-01

    The Department of Housing and Urban Devlopment (HUD) residential solar heating and cooling demonstration program provided funding support for over 600 solar projects. These projects provide the largest single data base of solar heating and cooling experience now available. These data suggest that controls were problematic in many of the active and passive heating and domestic and domestic hot water systems in the program. This paper will assess the active system modes of operation and the control components as to their ability to perform as intended. A large number of systems in the demonstration program experienced control problems during testing, checkout, and operation (there were 238 reported control problems involving 192 systems). Frequently, trouble-shooting site visitors found control problems had disabled the whole system or caused a portion of the system to malfunction. The consequences are not as significant on the more carefully designed systems (i.e., the auxiliary still functions) but, on systems with inappropriately designed solar-auxiliary interfaces, the homeowners often were without adequate heat. The most common control problems involved excessive modes in system and, therefore, control design; errors in sensor set points, location, or installation; and poorly engineered or installed wiring to and from controller panels.

    A microgap flat panel display which includes a thin gas-filled display tube that utilizes switched X-Y "pixel" strips to trigger electron avalanches and activate a phosphor at a given location on a display screen. The panel utilizes the principal of electron multiplication in a gas subjected to a high electric field to provide sufficient electron current to activate standard luminescent phosphors located on an anode. The X-Y conductive strips of a few micron widths may for example, be deposited on opposite sides of a thin insulating substrate, or on one side of the adjacent substrates and function as a cathode. The X-Y strips are separated from the anode by a gap filled with a suitable gas. Electrical bias is selectively switched onto X and Y strips to activate a "pixel" in the region where these strips overlap. A small amount of a long-lived radioisotope is used to initiate an electron avalanche in the overlap region when bias is applied. The avalanche travels through the gas filled gap and activates a luminescent phosphor of a selected color. The bias is adjusted to give a proportional electron multiplication to control brightness for given pixel.

    Presented here are results of a test program undertaken to further define the response of the solar dynamic radiator to hypervelocity impact (HVI). Tests were conducted on representative radiator panels (under ambient, nonoperating conditions) over a range of velocity. Target parameters are also varied. Data indicate that analytical penetration predictions are conservative (i.e., pessimistic) for the specific configuration of the solar dynamic radiator. Test results are used to define the solar dynamic radiator reliability with respect to HVI more rigorously than previous studies. Test data, reliability, and survivability results are presented.

  16. Method and apparatus for collecting solar energy

    SciTech Connect

    Olsen, T.O.

    1981-11-17

    A method and device for collecting solar energy is the subject of this application. A glass cloth coated with a light absorbing resinous material is utilized as the collector panel. A glass cloth coated with a translucent resinous material is the preferred material for a cover panel that is disposed in spaced relationship to the collector panel. A framework holds the two cloth layers in spaced planar relationship and a heat exchange medium is placed in contact with the collector panel. The device is used by placing it in direct sunlight, preferably at an angle to maximize the effects of the solar radiation. Radiation striking the light absorbing glass cloth is quickly dissipated by the glass fibers thereby heating the transfer medium. The resinous material, preferably black for the collector panel, provides a highly absorptive surface for the solar radiation and also protects the glass fiber of the cloth from deterioration as a result of radiation or corrosion.

    A solar heat system is comprised of a panel or bank of heat collector modules each of which has a fluid-carrying tube of an elongated triangular shape in transverse cross section formed with longitudinally extended inwardly projected heat radiating fins. A tube is mounted within a concavo-convex reflector of a hyperbolic form such that the side walls of the tube are subjected to reflected rays of solar radiation over an effective range of solar exposure of about one hundred and fifty (150*) degrees. The reflected rays are concentrated in a longitudinally extended focal zone on each side wall of the tube and these zones of concentrated solar radiation move transversely of a side wall in response to the angle of the solar rays falling upon the reflector.

  15. What Is the Largest Einstein Radius in the Universe?

    SciTech Connect

    Oguri, Masamune; Blandford, Roger D.

    2008-08-05

    The Einstein radius plays a central role in lens studies as it characterizes the strength of gravitational lensing. In particular, the distribution of Einstein radii near the upper cutoff should probe the probability distribution of the largest mass concentrations in the universe. Adopting a triaxial halo model, we compute expected distributions of large Einstein radii. To assess the cosmic variance, we generate a number of Monte-Carlo realizations of all-sky catalogues of massive clusters. We find that the expected largest Einstein radius in the universe is sensitive to parameters characterizing the cosmological model, especially {sigma}{sub s}: for a source redshift of unity, they are 42{sub -7}{sup +9}, 35{sub -6}{sup +8}, and 54{sub -7}{sup +12} arcseconds (errors denote 1{sigma} cosmic variance), assuming best-fit cosmological parameters of the Wilkinson Microwave Anisotropy Probe five-year (WMAP5), three-year (WMAP3) and one-year (WMAP1) data, respectively. These values are broadly consistent with current observations given their incompleteness. The mass of the largest lens cluster can be as small as {approx} 10{sup 15} M{sub {circle_dot}}. For the same source redshift, we expect in all-sky {approx} 35 (WMAP5), {approx} 15 (WMAP3), and {approx} 150 (WMAP1) clusters that have Einstein radii larger than 2000. For a larger source redshift of 7, the largest Einstein radii grow approximately twice as large. While the values of the largest Einstein radii are almost unaffected by the level of the primordial non-Gaussianity currently of interest, the measurement of the abundance of moderately large lens clusters should probe non-Gaussianity competitively with cosmic microwave background experiments, but only if other cosmological parameters are well-measured. These semi-analytic predictions are based on a rather simple representation of clusters, and hence calibrating them with N-body simulations will help to improve the accuracy. We also find that these 'superlens

A panel which is transparent to sunlight is spaced from the said surface of the absorbent body so as to define therewith a passageway in which air contacts at least a substantial area of said surface so that air in said passageway absorbs heat transmitted from said surface when the collector is in use. The passageway has an inlet and an outlet and the absorbent body and panel are arranged with the outlet higher than the inlet so that heated air in the passageway tends to rise by convection towards the outlet. The building is provided with heating means including a circulation circuit for a heating fluid. Heat exchange means are coupled to said air passageway outlet of the solar energy collector for passage of heated air therethrough. The heat exchange means are also coupled to the circulation circuit of the building heating means and are arranged to permit heat transfer between said heated air and the heating fluid. A return air flow conduit is coupled between the heat exchange means and the inlet of the air passageway of the solar energy collector for returning heated air from the heat exchange means to the air passageway for recirculation.

    The reduced force coefficients were measured for H{sub 2}, N{sub 2}, CO, and CO{sub 2} incident upon a solar panel array material, SiO{sub 2}-coated Kapton, Kapton, and Z-93-coated Al. The coefficients were determined by measuring both the magnitude and direction of the force exerted on the surfaces by molecular beams of the gases. Measurements were made at angles of incidence of 0{degree}, 25{degree}, 50{degree}, 75{degree}, and 85{degree}. The forces were measured using a torsion balance with the surfaces mounted on the end of the lever arm. The absolute flux densities of the molecular beams were measured using a second torsion balance with a beam stop mounted on the lever arm that nullified the force of the scattered molecules. Flux measurements were also made using the effusive method. Standard time-of-flight techniques were used to determine the flux-weighted average velocities of the molecular beams. These velocities ranged from 1670 to 4620 m/s. The overall uncertainty in the reduced force coefficient measurements was estimated to be less than {plus_minus}10{percent}. These measurements were used to obtain the magnitude and direction of the flux-weighted average velocity of the scattered molecules, and also the flux-weighted translational kinetic energy of the scattered molecules. Analysis of this information provided insight into the microscopic details of the gas-surface interaction potential energy surface. {copyright} {ital 1998} {ital The American Physical Society}

    2015-01-07

    When geologist John Rakovan needed better tools to investigate whether a dazzling 217.78-gram piece of gold was in fact the world's largest single-crystal specimen - a distinguishing factor that would not only drastically increase its market value but also provide a unique research opportunity - he traveled to Los Alamos National Laboratory's Lujan Neutron Scattering Center to peer deep inside the mineral using neutron diffractometry. Neutrons, different from other probes such as X-rays and electrons, are able to penetrate many centimeters deep into most materials. Revealing the inner structure of a crystal without destroying the sample - imperative, as this one is worth an estimated $1.5 million - would allow Rakovan and Lujan Center collaborators Sven Vogel and Heinz Nakotte to prove that this exquisite nugget, which seemed almost too perfect and too big to be real, was a single crystal and hence a creation of nature. Its owner, who lives in the United States, provided the samples to Rakovan to assess the crystallinity of four specimens, all of which had been found decades ago in Venezuela.

    The plasma panel sensor (PPS) is a gaseous micropattern radiation detector under current development. It has many operational and fabrication principles common to plasma display panels (PDPs). It comprises a dense matrix of small, gas plasma discharge cells within a hermetically sealed panel. As in PDPs, it uses non-reactive, intrinsically radiation-hard materials such as glass substrates, refractory metal electrodes, and mostly inert gas mixtures. We are developing these devices primarily as thin, low-mass detectors with gas gaps from a few hundred microns to a few millimeters. The PPS is a high gain, inherently digital device with the potential for fast response times, fine position resolution (< 50 m RMS) and low cost. In this paper we report here on prototype PPS experimental results in detecting betas, protons and cosmic muons, and we extrapolate on the PPS potential for applications including detection of alphas, heavy-ions at low to medium energy, thermal neutrons and X-rays.

    Solar ADEPT Project: CU-Boulder is developing advanced power conversion components that can be integrated into individual solar panels to improve energy yields. The solar energy that is absorbed and collected by a solar panel is converted into useable energy for the grid through an electronic component called an inverter. Many large, conventional solar energy systems use one, central inverter to convert energy. CU-Boulder is integrating smaller, microinverters into individual solar panels to improve the efficiency of energy collection. The University’s microinverters rely on electrical components that direct energy at high speeds and ensure that minimal energy is lost during the conversion process—improving the overall efficiency of the power conversion process. CU-Boulder is designing its power conversion devices for use on any type of solar panel.

    1981-12-29

    Thin solar collecting panels are described made from arrays of small rod collectors consisting of a refracting dielectric rod lens with an absorber imbedded within it and a reflecting mirror coated on the back side of the dielectric rod. Non-tracking collector panels on vertical walls or roof tops receive approximately 90% of solar radiation within an acceptance zone 60/sup 0/ in elevation angle by 120/sup 0/ or more in the azimuth secto with a collector concentration ratio of approximately 3.0. Miniaturized construction of the circular dielectric rods with internal absorbers reduces the weight per area of glass, plastic and metal used in the collector panels. No external parts or insulation are needed as heat losses are low due to partial vacuum or low conductivity gas surrounding heated portions of the collector. The miniature internal absorbers are generally made of solid copper with black selective surface and the collected solar heat is extracted at the collector ends by thermal conductivity along the absorber rods. Heat is removed from end fittings by use of liquid circulants. Several alternate constructions are provided for simplifying collector panel fabrication and for preventing the thermal expansion and contraction of the heated absorber or circulant tubes from damaging vacuum seals. In a modified version of the internal absorber collector, oil with temperature dependent viscosity is pumped through a segmented absorber which is now composed of closely spaced insulated metal tubes. In this way the circulant is automatically diverted through heated portions of the absorber giving higher collector concentration ratios than theoretically possible for an unsegmented absorber.

Several alternate constructions are provided for simplifying collector panel fabrication and for preventing the thermal expansion and contraction of the heated absorber or circulant tubes from damaging vacuum seals. In a modified version of the internal absorber collector, oil with temperature dependent viscosity is pumped through a segmented absorber which is now composed of closely spaced insulated metal tubes. In this way the circulant is automatically diverted through heated portions of the absorber giving higher collector concentration ratios than theoretically possible for an unsegmented absorber.

  12. Solar-hydrogen energy system for Pakistan

    SciTech Connect

    Lutfi, N.

    1990-01-01

    A solar-hydrogen energy system has been proposed for Pakistan as the best replacement for the present fossil fuel based energy system. It has been suggested to produce hydrogen via photovoltaic-electrolysis, utilizing the available non-agricultural sunny terrain in Baluchistan region. There will be a desalination plant for sea water desalination. The area under the photovoltaic panels with the availability of water would provide suitable environment for growing some cash crops. This would change the cast useless desert land into green productive farms. In order to show the quantitative benefits of the proposed system, future trends of important energy and economical parameters have been studied with and without hydrogen introduction. The following parameters have been included: population, energy demand (fossil + hydrogen), energy production (fossil + hydrogen), gross national product, fossil energy imports, world energy prices, air pollution, quality of life, environmental savings due to hydrogen introduction, savings due to the higher utilization efficiency of hydrogen, by-product credit, agricultural income, income from hydrogen sale, photovoltaic cell area, total land area, water desalination plant capacity, capital investment, operating and maintenance cost, and total income from the system. The results indicate that adopting the solar-hydrogen energy system would eliminate the import dependency of fossil fuels, increase gross product per capita, reduce pollution, improve quality of life and establish a permanent and clean energy system. The total annual expenditure on the proposed system is less than the total income from the proposed system. The availability of water, the cash crop production, electricity and hydrogen would result in rapid development of Baluchistan, the largest province of Pakistan.

    2010-02-05

    The development of microsatellites requires the development of engines to modify their orbit. It is natural to use solar energy to drive such engines. For an unlimited energy source the optimal thruster must use a minimal amount of expendable material to minimize launch costs. This requires the ejected material to have the maximal velocity and, hence, the ejected atoms must be as light as possible and be ejected by as high an energy density source as possible. Such a propulsion can be induced by pulses from an ultra-short laser. The ultra-short laser provides the high-energy concentration and high-ejected velocity. We suggest a microthruster system comprised of an inflatable solar concentrator, a solar panel, and a diode-pumped fiber laser. We will describe the system design and give weight estimates.

    SciTech Connect

    Mcclintock, M.

    1983-01-18

    A solar window which can alternatively act either as a passive solar heat collector or an active solar heat collector. A substantially transparent pair of panels are mounted in opposed position to each other and define a chamber therebetween. When it is desired to admit solar energy to the structure in which the window is mounted, air is permitted to be retained in the chamber and sunlight to pass through the window to thus heat the interior of the structure. When heat is not required in the structure, a second fluid which may be an optically dense solar energy absorbent or reflective fluid is passed through the chamber so as to respectively absorb or reflect the sunlight passing into the chamber, and in this way reduce the amount of solar heat passing through the window, and, in the case of an absorbent fluid, to retain the heat for later use. Pleasing architectural aesthetics or practical advantages in the case of greenhouses may further be obtained by passing colored fluid through the chamber which fluid may additionally achieve the selective absorption of light of certain wavelengths passing through the window. An alternative embodiment of the invention includes providing the inside window panel with grooves adjacent the chamber and disposed at such an angle thereto that radiation in a spectral region in which the material of said window is at least partially transparent attempting to pass outwardly through said window is substantially reflected back into said structure. Accordingly the angle at which the walls of such grooves are disposed must exceed the critical angle to support total internal reflection for the particular materials utilized.

    1983-09-20

    A load-bearing building panel capable of forming an external wall cladding or roof component has a solar heat collecting capacity in the form of channels for heat exchange fluid incorporated in the fabric of the panel. The panel is made of a structural plastics material, such as G.R.P. laminate, successive layers being moulded to simulate tiles. On the back or underside, longitudinal reinforcing beams are built in during laying up of the panel. Between the beams cores or formers defining a matrix or channels are encapsulated in layers of the G.R.P. Wax cores are melted or dissolved out after curing of the panel; metal formers remain embedded in the fabric of the panel. The matrix is connected by flow and return pipes to a heat exchange system within the building. Panels intended for roofing have ridge flanges and wall plates moulded into the substrate at the appropriate pitch angle, and a split capping tube embraces the ridge flanges. A pitched roof formed by oppositely sloping panels is self-supporting. An integral box girder can also be formed across the underside of the panel at the eaves to rest on the top of the external wall to be loaded with concrete in situ so as to anchor the roof on the walls.

    In this paper, we review the latest developments in the area of printing technologies with an emphasis on the fabrication of control-embedded photovoltaics (PV) with on-board active and passive devices. We also review the use of power converters and maximum power point tracking (MPPT) circuits with PV panels. Our focus is on the investigation of the simplest implementations of such circuits in view of their integration with solar cells using printing technologies. We see this concept as potentially enabling toward further cost reduction. Besides a discussion as to feasibility, we shall also present some projections and guidelines toward possible integration.

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

    2010-12-03

    Considerable interest has been expressed for developing a stable U.S. production capacity for medical isotopes and particularly for molybdenum- 99 (99Mo). This is motivated by recent re-ductions in production and supply worldwide. Consistent with U.S. nonproliferation objectives, any new production capability should not use highly enriched uranium fuel or targets. Conse-quently, Aqueous Homogeneous Reactors (AHRs) are under consideration for potential 99Mo production using low-enriched uranium. Although the Nuclear Regulatory Commission (NRC) has guidance to facilitate the licensing process for non-power reactors, that guidance is focused on reactors with fixed, solid fuel and hence, not applicable to an AHR. A panel was convened to study the technical issues associated with normal operation and potential transients and accidents of an AHR that might be designed for isotope production. The panel has produced the requisite AHR licensing guidance for three chapters that exist now for non-power reactor licensing: Reac-tor Description, Reactor Coolant Systems, and Accident Analysis. The guidance is in two parts for each chapter: 1) standard format and content a licensee would use and 2) the standard review plan the NRC staff would use. This guidance takes into account the unique features of an AHR such as the fuel being in solution; the fission product barriers being the vessel and attached systems; the production and release of radiolytic and fission product gases and their impact on operations and their control by a gas management system; and the movement of fuel into and out of the reactor vessel.

    A thin film photovoltaic panel includes a backcap for protecting the active components of the photovoltaic cells from adverse environmental elements. A spacing between the backcap and a top electrode layer is preferably filled with a desiccant to further reduce water vapor contamination of the environment surrounding the photovoltaic cells. The contamination of the spacing between the backcap and the cells may be further reduced by passing a selected gas through the spacing subsequent to sealing the backcap to the base of the photovoltaic panels, and once purged this spacing may be filled with an inert gas. The techniques of the present invention are preferably applied to thin film photovoltaic panels each formed from a plurality of photovoltaic cells arranged on a vitreous substrate. The stability of photovoltaic conversion efficiency remains relatively high during the life of the photovoltaic panel, and the cost of manufacturing highly efficient panels with such improved stability is significantly reduced.
