Özet:

One of the most widely used renewable energy sources is solar photovoltaic (PV) electricity. PV modules lose efficiency as they become hotter. It is therefore critical to find ways to make them more efficient even when they are extremely hot. Due to the heat generated by the absorbed sunlight, the panel's output and efficiency, performance, and longevity are reduced. In order to keep PV panels from overheating, cooling devices can be used to lower the temperature of the cells. Operational considerations include cooling the operating surface of solar photovoltaic systems. Proper cooling can extend the life of solar panels. Thermal exhaust from cooling systems can be used for both domestic and commercial purposes. A PV module's output performance was evaluated in this study by conducting trials involving both front and back surface cooling. To cool the PV panel's back surface, wet grass (dry grass with water supply) was used, while a mass rate of water was used to cool the panel's front surface. Perforated pipes are positioned on both sides of the panel's front surface to allow for water from the tank to be distributed. The experiment resulted in a temperature drop of 21.23 degrees Fahrenheit. The panel's output power rose by 28.6 %as a result of this. The cooled PV module's average efficiency was 34.96 %. When it came to PV system energy yield in the field, the proposed approach of front surface cooling had a significant impact.
