Solar energy is utilized by converting it to electrical energy using solar photovoltaic (PV). Solar energy is absorbed and converted by PV up to 30%. The remaining energy is wasted in the form of heat which raises the surface temperature and causes damage to the solar photovoltaic. So that it can affect the performance produced by solar photovoltaic. Lowering the temperature of solar photovoltaic using a heatsink as a heat transfer medium. The effectiveness of the heatsink is influenced by the air flow so as to facilitate heat transfer. Therefore, the study conducted experiments with the addition of an air concentrator to be installed as a support for heatsink performance in the solar photovoltaic cooling process. The addition of a concentrator at the peak intensity of the solar panel can reduce the working temperature by 4.8°C. Solar panels with concentrators can increase the maximum power value by 1.45 W and efficiency by 0.38% higher than panels without concentrators.
