Increasing the efficiency of photovoltaic panels through cooling water film

Through this paper, we proposed a solution to increase efficiency photovoltaic panels. So we used a device that makes a water film on the surface of panels, obtaining simultaneously cleaning and decreasing the operating temperature of the panel. To highlight the results, the output parameters were measured when applying a water film. Throughout the experiment panel temperature was monitored using a thermo-vision camera, with or without water film.
