An Experimental and Economical Assessment on Cooling the Photovoltaic (PV) Panels by Fins

Photovoltaic (PV) power plant is one of the most important renewable power generation methods, which is rapidly developing. One of the weak points of PV power plants is the negative effects of increasing the cells temperature, on their power generation. In this study, a simple and low cost method is proposed to reduce the temperature of these panels. By using the numbers of aluminum fins on the back surface of photovoltaic panels under two different irradiation, the temperature reduction up to 7.4 °C was observed, which caused to 2.72 % increasing in efficiency. Finally, an economical assessment of the offered scheme based on output power of PV panels has been carried out, which shows a suitable economic justifiability.
