Abstract
The research investigates the usage of fins fastened to a solar panel's rear surface for passive cooling purposes. In the research, solar modules with air conditioning were compared to modules with connected fins acting as a heat sink to cool them. The former served as the benchmark for comparison. The research explores two approaches for cooling modules with fins: ventilation air and still air. The research looked at the heat transfer by photovoltaic panels with and without fins to examine the effects of the environment and solar radiation on the performance of solar cells. The inquiry was carried out ostensibly. According to the findings, the use of fins for cooling reduced cell temperature and improved electrical and thermal efficiency. The estimated performance values of PVT solar cells obtained by using the COMSOL software and the experimental tests carried out during the daytime were reasonably in accord. At midday, the cell temperature decreased by a maximum of 2.8 Co, while electrical and thermal efficiency increased by a maximum of 18.2% and 55.13%, respectively. Good agreement between experimental and numerical results
