Abstract

The efficiency of solar photovoltaic (PV) systems significantly decreases as the surface temperature of the panels increases due to prolonged solar radiation. This study aims to enhance the performance of solar PV by implementing an active water spray cooling system. The system utilizes a series of nozzles controlled by a thermostat to spray water when the surface temperature reaches 40℃ and stops at 30℃. Experimental tests were conducted by comparing PV panel performance with and without the cooling system in open environmental conditions. The results demonstrated that the water spray system effectively reduced the average surface temperature from 50.47℃ to 33.97℃, resulting in a power output increase from 88.48 W to 112.36 W and efficiency enhancement from 13.83% to 23.38%. These findings suggest that the proposed active cooling method significantly improves PV performance and supports the use of clean energy, particularly in tropical regions like Bali.
