PERFORMANCE OF A SOLAR PANEL WITH WATER IMMERSION COOLING TECHNIQUE

Abstract: With the increase in surface temperature of solar cells or panels their efficiency decreases quite dramatically. To overcome the heating of solar cell surface, water immersion cooling technique can be used i.e. it can be submerged in water so as to maintain its surface temperature and provide better efficiency at extreme temperatures. In this study, electrical parameters of solar cell were calculated which showed that the cooling factor plays an important role in the electrical efficiency enhancement. Solar cell immersed in water was monitored under real climatic conditions, cell surface temperature can be controlled from 31-39 C. Electrical performance of cell increases up to great extent. Results are dicussed; panel efficiency has increased about 17.8 % at water depth 1cm. The study can give support to the Concentrated Photovolatics System by submerging the solar cells in different mediums
