Development of an automated spray cooling system for solar panel application with different cooling fluids.

Cooling fluids are fluids that function to remove heat from certain object. In this paper, different cooling fluids were used to cool down the temperature of solar panel. The main objective is to investigate the effects of different type of working fluid on the cooling performance of the solar panel. The cooling fluids that have been used are water, ethylene glycol and mixture of ethylene glycol and water. These different cooling fluids will be used to determine the effects to the solar panel temperature, the power output of solar panel temperature and the efficiency of the cooling fluids on cooling performance. In this research work, the power output of the solar panel is the parameter that determines the cooling performance of working fluids. Longer cooling time of the solar panel shows a significant increase in solar panel power output. The findings revealed that the solar panel power output has achieved the highest efficiency at 8.18% when the water is introduced as cooling fluid compared to ethylene glycol at 3.18% efficiency and mixture of water and ethylene glycol at 1.91% efficiency.
