  • This paper describes a proposed international qualification standard for photovoltaic (PV) systems generating electricity from concentrated sunlight. The standard's purpose is to provide stress tests and procedures to identify any component weaknesses in a system. If no weaknesses are identified during qualification, both the manufacturer and the customer can expect a more reliable product. In 2002, we began developing the standard, under the auspices of the International Electrotechnical Commission (IEC), that would describe testing procedures for concentrator PV systems using reflecting (mirrors) or refractive (lenses) optics for focusing sunlight onto solar cells. The initial draft of the IEC standard wasmore » based on the first concentrator PV qualification standard published by the Institute of Electrical and Electronics Engineers (IEEE) in the United States in 2001. Well-developed U.S. concentrator technologies use refractive optics, and the IEEE standard needed improvement for testing systems with reflective optics. Furthermore, with record III-V solar cell efficiencies above 37%, concentrator PV developers around the world would like to incorporate such cells into their next generation of technologies. The paper will highlight significant differences between the proposed IEC standard and the earlier IEEE standard.« less
  • A preliminary engineering design has been developed for a photovoltaic central station power plant that utilizes tracking concentrator photovoltaic (PV) arrays. This effort is part of a continuing research program funded by The Aerospace Corporation with the objective of defining and developing specifications for the subsystems and interfaces associated with the design of a photovoltaic power plant. In previous work in this program a power plant design using flat plate photovoltaic technology was developed. The principles developed in the earlier work have now been applied to a design that uses tracking concentrator photovoltaic arrays( ). The approach taken was tomore » use electric utility design practices wherever possible and to provide sufficient definition of equipment to permit subsequent preparation of engineering cost estimates. The study has produced single-line electrical diagrams, site layout drawings, and functional diagrams for a station nominally rated at 200MW.« less
  • This paper discusses efforts led by two companies (PowerMark Corporation and Sunset Technologies Inc.) to support both U.S. domestic and international photovoltaic (PV) system and component certification and test facility accreditation programs and the operation of the International Electrotechnical Commission (IEC) Technical Committee 82 (TC-82) Photovoltaic Energy Systems. International and national PV certification/accreditation programs are successfully facilitating entry of only the highest quality PV products into the marketplace. Standards also continue to be a cornerstone for assuring global PV product conformity assessment, reducing non-tariff trade barriers, and ultimately improving PV products while lowering cost.
  • The design and development of an innovative photovoltaic concentrator which utilizes a low cost molded Fresnel lens is described. The lens design and fabrication are discussed, as well as the design of the collector module and tracking structure. A description of instrumentation developed to aid in the testing of lenses and solar cells is presented, and includes the test results.
  • In order to reduce the array-field balance-of-system (BOS) costs and the engineering design costs, modular designs, optimized for minimum life-cycle energy cost, have been developed for flat-panel and concentrator photovoltaic installations. Application experiments and other photovoltaic (PV) systems recently installed had shown that these cost elements had to be substantially reduced before PV power systems could be cost-effective for grid-connected applications, regardless of the cost of the PV cells/modules. The characteristics of the modular array-field designs developed are described in another paper at this conference. This paper describes the costs estimated and the life-cycle energy cost analyses performed for themore » developed modular designs. In example analyses of these designs, the array-field BOS costs contribute only 0.9 to 1.2 cents per kWh to the levelized energy cost of generated electricity.« less
