A study on the performance of PV/T system based on windows

KEYWORD: PV/T based on windows; Monocrystalline silicon; Building energy conservation ABSTRACT: A PV/T system based on windows is designed and fabricated to investigate the per- formance of PV/T system and the influence on the energy saving effect in Nanjing. A water-cooling device is installed behind the PV cells to improve the power generation efficiency and its cooling ef- fect is better than air-cooling. Experiments on the PV/T system in every season are performed in this paper. The energy consumption of the test room with normal glass windows and PV/T based win- dows is compared, and the seasonal power saving effect under different cooling conditions is sum- marized. It is concluded that the best energy saving effect of PV/T system can be achieved by using different cooling water flow rate in several seasons.
