Enhance the Thermal Efficiency of Solar Panels Using Extended Fins

Temperature affects the efficiency of solar panels to a large extent, with high temperatures causing lower energy conversion efficiency and higher material degradation. This study explores a novel passive cooling system for solar panels utilizing aluminium sheets of different shapes such as rectangle, half-circle, and triangle to increase heat dissipation. Aluminium, which is highly conductive thermally and light in weight, is an efficient cooling medium that helps transfer heat away from the surface of the panel. Comparative experimental analysis is done on the efficiency of aluminium sheet designs to cool, analyzing how they affect temperature reduction, panel efficiency, and structural viability. Thermal imaging and live temperature measurement are used to measure heat distribution and patterns of dissipation. The research finds that shape and orientation are of utmost importance in maximizing cooling performance, with some designs being superior to others through enhanced airflow and radiation effects. The research points to the viability of aluminium-based cooling methods as a low-cost, eco-friendly means to reduce overheating in solar photovoltaic systems, thus enhancing overall energy efficiency and lifespan. Future studies may further optimize design parameters and incorporate additional cooling upgrades, including phase change materials or advanced coatings, to optimize thermal control.
