Design of Solar Panel Cooling System Based on Natural Circulation Using Ground Source Energy

Abstract

The performance of solar panels is greatly affected by high temperatures, so a cooling system is required to improve their efficiency. Various cooling methods have been explored, including passive cooling, active cooling, and hybrid cooling systems. This research applies the passive cooling method by designing a solar panel cooling system based on natural circulation using ground source energy. This method relies solely on natural cycles so that the system can operate sustainably. The design of this system uses the experimental method. Analysis was conducted to compare the power output generated by solar panels with a cooling system using ground source energy and solar panels without a cooling system. The test results show that the system is able to reduce the surface temperature of the solar panel with an average temperature of 41,80% compared to the solar panel without a cooling system with an average temperature of 43,08%. In addition, the solar panel cooling system using ground source energy is able to obtain a power efficiency of 8,24% with maximum power reaching 72Watt / Day.
