Comparative Analysis of Combined Flat-Plate PV/T Collectors with Separate Photovoltaic and Thermal Collectors

摘要

The conditions under which a combined photovoltaic/thermal (PV/T) collector is more cost effective than separate flat-plate photovoltaic and thermal collectors are determined. The annual performance of the separate PV/T system and four different combined PV/T systems are simulated. Based on the equivalent electrical and thermal outputs and the 1986 DOE cost goal for PV modules (70 cents/Wp), the maximum allowable incremental cost to upgrade the conventional thermal collector to a combined PV/T collector is determined. For all of the cases considered in this study, the separate PV/T collectors are more cost effective than the combined PV/T collectors. (ERA citation 06:019989)
