Actively cooled concentrating photovoltaic systems have the added advantage of making useful thermal energy available for industrial and commercial applications. Three generic types of collectors are available for photovoltaic-thermal (PV-T) applications: linear parabolic trough (LPT), line focus Fresnel (LFF), and point focus Fresnel (PFF). Each of the three types of PV-T systems was modeled and simulation was performed using SOLCEL-II to obtain instantaneous efficiencies. The calculated efficiencies were consistent with those measured, providing confidence in the modeling methodology. Annual array efficiencies were then calculated using an hour-by-hour simulation and TMY data for Albuquerque, New Mexico. Based on annual thermal and electrical efficiencies, array costs, land use and shading factors, the three types of collectors were evaluated with respect to collector costs and land area usage per kilowatt electric provided by the array.
