Design Of A 20 Kwp Photovoltaic Concentrator Experiment At Fauquier High School Warrenton Virginia PDF Download

Solar Corporation designed a photovoltaic concentrator system for Fauquier High School in Warrenton, Virginia, 40 miles west of Washington, DC. The system provides both electrical energy from the photovoltaic modules and thermal energy from the cooling of those modules. Direct current electrical energy from the photovoltaic modules will be first converted to ac and then used to provide power for lighting in the vocational/technical building and the system control building. Instead of being rejected, the thermal energy collected is stored in a 6500-gallon tank for use in the wintertime to provide heat for a greenhouse located adjacent to the array. The photovoltaic system supplies 20 kWp of electrical power by means of 40 6' wide by 10' long parabolic-cylinder collectors mounted in a polar mode. The photovoltaic power is fed into a switching system to feed either photovoltaic power or utility power to nine 2 kW lighting circuits in the vocational technical school and to fan, pump and auxiliary loads in the control building. Conceptual system design, systems analysis, and prototype performance are described. (WHK).
