Photovoltaic module performance analysis of aluminum and zinc thin metal sheet attached with direct current brushless fans cooling system

Physic variables of photovoltaic (PV) module performance decreased is excess of solar radiation and operating temperature. The PV module operating temperature increased lead to the PV module electrical efficiency decreased. The PV module operating temperature increased with solar irradiance is increased to exceed a certain limit. In order to maintain the performance of PV module in better condition, a cooling system is necessary to be applied on the PV module system. In the present work, DC brushless fans act as a cooling system integrated with thin metal sheet attached at the back part of the PV module. Two types of thin metal sheet that is aluminum sheet and zinc sheet have been used and compared in this investigation. The result of the cooling system can immensely increase the output power generated by the PV module. The effect of DC fans cooling system attached with thin aluminum sheet (DCFTAS) can be provided better performance than the DC fan cooling system with thin zinc sheet (DCFTZS). The PV module with DCFTAS can be produced additional 17.63 % than PV module with DCFTZS.
