Abstract:
Photovoltaic (PV) panel is the heart of solar system generally has a low energy conversion efficiency available in the market. PV panel temperature control is the main key to keeping the PV panel operate efficiently. This paper presented the great influenced of the Automatic cooling system in reduced PV panel temperature. A cooling system has been developed based on cooling coil convection induced by AC water pump as cooling mechanism. Copper cooling coil was attached at the back side of PV panel will extract the heat energy distributed and cool down the PV panel. The working operation of AC water pump controlled by the Arduino micro controller, which is depending on the value of PV panel temperature. Experiments were performed with and without cooling mechanism attached to the backside PV panel. The whole PV system was subsequently evaluated in outdoor weather conditions. As a result, it is concluded that there is an optimum temperature of the module required as cooling mechanism in producing efficient electrical output from a PV panel. The study clearly shows how cooling mechanism improves the performance of PV panel at the hot climatic weather. In short, the reduction of PV panel temperature is very important to keep its performance operated efficiently.
