Increasing the output power of solar panel by using cooling system

Abstract

Solar panel is a device to convert light energy from the sun into electrical energy, most of solar panel is made from semiconductor such as silicon. Solar panel is still having many disadvantages such as expensive prices, low efficiency, the power output that depended on light intensity and temperature, etc. During the day, solar panel temperature could increase and affect the power output. It is found that temperature would reduce solar panel voltage output that also reduce the power output. In this research, 100WP Monocrystalline solar panel power output will be enhanced by using cooling system to reduce the temperature of the solar panel. Cooling system of the solar panel is applied by flowing the water on the surface of the solar panel using 12V DC water pump. The experiment starts from 11:00 AM to 01:00 PM. The result of this experiment is the power output of the solar panel increased up to 5.79 Watt with the average about 2.96 Watt and the temperature of the solar panel decreased by 20.99°C. The temperature of the solar panel without cooling is about 52.83°C and with the cooling system is about 31.85°C.
