Cooling of the solar cells is a critical issue, especially when designing concentrating photovoltaic (PV) systems. In the present work, the cooling of a photovoltaic panel via Water immersion technique is investigated. The aim of this project is to optimize the efficiency of a solar panel by submerged it in distillated water at different depths. Experiment is done for polycrystalline silicon panel. An evident increase of efficiency is found with increasing the water depth. Results are discussed; thermal drift has been reduced and the solar panel efficiency has increased by about 11% at water depth 6 cm.
