Experimental Investigation of The Efficiency of Solar Panel Over Which Water Film Flows

The most important energy source of the world is sun. Solar can be converted to electricity by using photovoltaic (PV) solar panels. It known that maximum electrical efficiency PV panels around 15%-20%. Therefore, it clear are not very efficient. This due some reasons. One these reasons increase in temperature panel. should cooled means any cooling methods. For this reason, study, effect on has been investigated experimentally. purpose, an experimental setup, containing two with and without cooling, was installed. In unlike general literature a flowing water film, which panel, obtains cooling. determined power output panel greater than one. A 11.143 W gained from obtained film. average designed system about 9.51%. As result, specified approximately 13.69% more efficient uncooled uncertainty analysis also performed. ± 0.16130% 1.28366%, respectively.
