The Experimental Study of New-Type Water-Cooling PV/T Collector

Abstract:

A new photovoltaic/thermal (PV/T) system based on the micro plate heat pipe is established in this paper, and the experimental study is conducted for nature convection, forced circulation cooling and common PV module. the experiment carried out on May showed that the highest temperature were 50°C and 52°C respectively for nature convection and forced circulation cooling module, the daily average electrical efficiency were relatively increased by 13.1% and 6.1% than common PV modules, the total efficiency ηo reached 54.2% and 50.3%, and the primary-energy saving rate were 73.1% and 68%.the result indicates that in the new PV/T system the temperature of the PV modules is reduced, the electrical efficiency is keeping at a high level, and the waste heat can be made good use to get hot water, therefore the solar energy utilization efficiency was raised greatly.
