Experimental Investigation of Photovoltaic Panel Cooling by Uniformly Flowing Water on the Top Surface for Efficiency Improvement
摘要
The study done in this article furnish the results of an experimental investigation on the cooling of solar photovoltaic (PV) panel with water flowing uniformly over the top surface. An experimental setup was designed, fabricated, and put to testing in real outdoor environment in the geographical region of Chandigarh, India. To overcome non-uniformities in the flow, various trials were made and a cuboidal vessel was designed. About a 50% decrease in temperature was observed. An improvement of about 17% in efficiency was observed by cooling the PV panel, it increased from 11.83% to 13.83%.
