Solar Panel Performance Improvement using Heatsink Fan as the Cooling Effect

Currently, technological developments in Indonesia are growing very fast, one of which is technology in the field of renewable energy. As a tropical country, Indonesia gets a lot of daylight. National Energy Board data on solar irradiation in Indonesia with irradiation distribution in the Western Region of Indonesia (KBI) around 4.5 kWh / m² / day and in Eastern Indonesia (KTI) around 5.1 kWh / m² / day. We must focus on the development of renewable energy and be a solution to the current energy problems where fossil energy is increasingly depleted of its supplies, especially solar energy with unlimited resources. The problem is if you want to build a solar power plant (PLTS) in a tropical country where the ambient temperature is quite hot if you want to improve the performance of the solar panel you must get the maximum open circuit voltage by maintaining the standard operational temperature of the solar panel. Polycrystalline Sankelux solar panel type SPV 1610-100 with a standard temperature of 25°C will produce a maximum open circuit Voc voltage of 22.94 V. The study was conducted in Palembang between 9:00 a.m. to 3:00 p.m. where the temperature could reach 38°C, the temperature on the surface of the solar panel reached 55°C and solar radiation reached 1447 W / m² at 12:30 a.m. By adding cooling heatsink fan to keep the surface temperature of the solar panel close to the standard operational temperature, the temperature decreased to 15 ° C so we could maximize the open circuit voltage.
