Phase Changing Material Usage to Increase the Efficiency of Photovoltaic Panels

Abstract

Energy based on renewable energy sources continues to meet the increasing need of growing population. In renewable energy production, not only energy production but also efficient using is crucial. In recent years, photovoltaic panels, which are increasingly used and highly important, have warmed on the surface due to the radiation energy emitted by the sun, and this warmth reduces the efficiency of the panel. In this study, it is aimed to reduce this efficiency loss by using phase changing material with latent heat which is one of the thermal energy storage methods. One of the two solar panels placed parallel to the ground was filled with phase changing material. With this, it is aimed to cool photovoltaic panel by using calcium chloride hexahydrate phase changing material; and radiations air temperature, current, voltage, power, surface temperature, efficiency graphs were obtained. As a result of simultaneous measurements, the increase in yield was 2.95%.
