Enhancing the Power and Efficiency of Photovoltaic Panel Using Heat Sinks with fans

With its tremendous environmental and economic potential, the renewable-energy sector is quickly gaining traction as a new growth area for many countries. Solar energy is an essential primary energy source, particularly in rural areas. In recent years, solar panels have become increasingly popular for converting solar energy to electrical energy. In this work, a new passive cooling system arrangement was planned and design. It is made up of a two identical heat sink made with four DC fans which is attached with the back part of the solar cell in order for improving the solar cell’s power efficiency by providing suitable cooling conditions. The system will consist of Temperate sensor, ATmega328P microcontroller (Arduino Nano), Heat sink, Fan, and a solar Panel (5.5v). The results showed that is the solar the temperature of the cell decreased in average output from 41.45T to 39.37 T with enhancements about 5 C % with using passive cooling system. The cooling causes to increase the average output current from 0.388 A and 0.428A with enhancements about 9.34 % for the gained current. The cooling causes to increase the average output voltage from 18.52v to 19.92v with enhancements about 7.03% for the gained voltage. The cooling causes to increase the average output power from 7.22W to 8.56W with enhancements about 13.34 % for the gained current. The cooling causes to increase efficiency with enhancements about 11% which is a good ratio that when using the cooling system.
