Original abstract

This study evaluates the thermal performance of five photovoltaic PV panels using steady-state thermal analysis in ANSYS. The panels include a standard PET backsheet panel, a PET + aluminum backsheet panel, a panel with only aluminum backsheet, and two finned configurations: one with PET + aluminum backsheet with angled fins, and another with only an aluminum backsheet with angled fins. Standard PET panels exhibited the highest PV cell temperatures (69.782 °C maximum, 60.746 °C minimum), while the PET + aluminum backsheet panel showed modest improvement (68.848 °C maximum, 62.93 °C minimum) due to enhanced lateral heat transfer. The panel with only aluminum backsheet displayed similar moderate reductions, confirming that PET alone has limited influence on thermal performance. The most significant temperature decreases and the most uniform thermal distribution were observed in the finned panels; the panel with only aluminum backsheet and angled fins reached PV cell temperatures of 58.503 °C maximum and 55.811 °C minimum. These results demonstrate that integrating angled fins with an aluminum backsheet effectively reduces localized heating, minimizes temperature gradients, and improves PV panel thermal reliability. However, these thermal improvements come at the cost of increased panel mass, rising from 26.54 kg in the standard PET panel to 39.797 kg in the finned aluminum design, highlighting the need to balance thermal benefits against structural and installation considerations.
