The University of Wyoming (UW) campus is serving as the site for a 50 kilowatt solar photovoltaic (PV) system. Three sub-systems were sited and built on the UW campus in 1996. The first sub-system, a 10 kW roof-integrated system of PV roof tiles is located on the roof of the Engineering Building. The second sub-system -a 5 kW rackmounted, ballasted PV system is on a walkway roof of the Engineering building. The third sub-system is a 35 kW shade structure system and is located adjacent to the parking lot of the university's football stadium. The three sub-systems differ in their design strategy since each is being used for research and education at the university. Each sub-system, being located at some distance away from one another, supplies a different part of the campus grid. Efforts continue at setting up a central monitoring system which will receive data remotely from all locations. A part of this monitoring system is complete. While the initial monitoring data shows satisfactory performance, a number of reliability problems with PV modules and inverters have delayed full functionality of the system.

PowerLight Corporation (PowerLight) has completed its Photovoltaic Manufacturing Technology (PVMaT) 5A1 subcontract, "PowerGuard ® Advanced Manufacturing," addressing the U.S. Department of Energy's PVMaT goals of manufacturing improvements directed toward innovative, low-cost, high-return, high-impact PV products. PowerLight's focus for this subcontract was its patented PowerGuard building-integrated PV roofing tile. The objective of the subcontract over its three-year duration was to continue the advancement of PowerLight's PowerGuard manufacturing improvements in order to reduce PowerGuard system costs, increase PowerGuard tile fabrication capability to 16-MW/year, and stimulate an increase in manufacturing of PV laminates, within the United States, by 2-MW/year. During Phases I and II of the subcontract, PowerLight developed the PowerGuard system and manufacturing process for high volume production and cost reduction, while improving product quality. During Phase III, PowerLight expanded market penetration through strategic commercial alliances and receipt of necessary commercial certifications.
