Phase Changing Material Usage to Increase the Efficiency of Photovoltaic Panels

The energy demand from renewable energy sources has been proportionally increased due to population growth. In renewable energy production, not only energy production but also efficient use is crucial. In recent years, photovoltaic panels, which are increasingly used and highly important in terms of renewable energy production, 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 then radiation, air temperature, current, voltage, power, surface temperature, efficiency graphs were obtained. As a result of simultaneous measurements, the increase in yield was found to be 2.95%.
