The performance of solar panels is incredibly addicted to the absorption of radiation. A number of the absorbed energy is converted into electricity, while the remainder transformed into heat. However, PV panels may experience intense heat that causes heat radiation in PV panels to increase. This radiation on the PV panel includes a negativeimpact on the output of voltage produced and has the potential to cut back the performance of the solar battery. Therefore, it is necessary to style a PV-Panel cooling system to take care of the temperature of the panel to not exceed its effective working temperature. This projectwork aims to take care of the PV-Panel temperature to not exceed the effective working temperature using Fins and PCM as a cooling medium. The variables used include the temperature distribution of the highest of the panel, the center panel, and therefore the bottom panel. The results showed that the employment of Fin and PCM maintains thetemperature of solar panels below 50oC, relatively better than the PV panels that use air as a cooler. An experiment is performed with and without modification of PV panel and the result shows an increase in conversion efficiency by 5–7%.
