Abstract

A combined 3 kW PV-thermal system has been proposed for home use. Combining PV and thermal conversion makes this system economically efficient and competitive with traditional power supplies. GaAs and Si concentrator solar cells have been measured under concentration as a candidate for use in this system. InGaP/GaAs tandem solar cells designed for 1-sun operation have been examined under concentration. The potential use of GaInP/GaAs tandem solar cells has been analyzed for this application. The properties of the thermal transfer unit of this system has been evaluated including the cooling of the solar cell holder
