A solar panel is a device that can convert sunlight into electrical energy. Solar panels are also commonly called photovoltaic cells which can be interpreted as electric light. The output power of static solar panels is considered less than optimal, so a solution is needed by making a cooling system with a heatsink and aluminum foil reflector, based on the solar panels must be in optimal conditions and can capture sunlight optimally. Therefore, it is hoped that the manufacture of a heat sink cooling system and aluminum foil reflector can be a solution to increase the output power of solar panel. In the cooling system and aluminum foil reflector, the output power of solar panels with the output power of static solar panels has increased with a percentage increase on March 10, 2021 by 55.10%, March 22 2021 by 34.91% and March 25 by 58.78%.
