<![CDATA[Indonesia has significant potential for New and Renewable Energy (NRE), including 450 MW of micro-hydro, 50 GW of biomass, 4.8 kWh/m²/day of solar energy, 3–6 m/s of wind energy, and 3 GW of nuclear energy. One form of NRE widely used by the public is solar energy harnessed through solar panel technology. A solar panel, or solar cell, is a device consisting of a collection of solar cells that absorb sunlight and convert it into electrical energy. Solar panels operate optimally at a normal ambient temperature of around 25℃. If the temperature of the solar panel rises above 25℃, its power output will decrease. For every 1°C increase, the efficiency of the solar panel decreases by 0.44%. This issue is addressed through a cooling method known as immersion. Immersion utilizes two cooling media: water coolant and super coolant. In this study, four experiments were conducted, in which the solar panels were immersed in each coolant using volumes of 3 and 6 liters. The results show that the maximum temperature reached with both types of coolant was essentially the same at 43°C. The voltage generated by both immersion methods was also the same at 17.2 volts. Super coolant immersion produced a current 0.14 A greater than water coolant immersion, with a maximum current of 1.15 A.]]>
