EXPERIMENTAL STUDY OF ELECTRICITY GENERATION BY PHOTOVOLTAIC THERMAL COLLECTORS: COMPARISON WITH CONVENTIOAL PHOTOVOLTAIC PANELS
A hybrid photovoltaic/thermal collector (PV/T) is designed to improve electrical efficiency and supply thermal energy and electrical energy simultaneously. In this work, A PV/T system was built, which includes PV/T collector, water tank, pump, measurement apparatus, and data collecting system. A conventional PV panel is installed for comparison. The study focuses on the electrical, thermal efficiency of the system, and the comparison of different components temperature. The results show that electrical efficiency of PV/T is remarkably improved by the cooling comparing with that of PV; meanwhile the thermal energy produced is also considerable. The highest water tank temperature for 21 days indicates there is an upper limit of water temperature which should be considered for practical use of hot water. Some suggestions for the optimization of the design of PV/T system are also given.
