Efficient Thermal Management of Hybrid Photovoltaic‐Thermal Solar Panels Using Phase Change Material for Industrial Applications

This study presents a novel thermal management approach for hybrid photovoltaic‐thermal (PVT) solar panels using phase change materials (PCMs) to enhance energy efficiency in industrial applications such as food processing, textiles, and chemicals. The research develops an adaptive system that integrates paraffin wax‐based PCMs infused with graphene to regulate panel temperature, improving both electrical and thermal performance. Paraffin waxes with phase change temperatures between 40 °C and 70 °C and latent heat capacities of 150–200 kJ kg −1 were selected for their thermal stability, conductivity, and low cost. Laboratory and field tests evaluated various PCM formulations and configurations under controlled and real‐world conditions. Key metrics, including temperature stability, electrical output, and thermal efficiency, were monitored using sensors and data loggers. Compared to conventional PVT systems, the PCM‐enhanced panels demonstrated a 28% increase in thermal efficiency, a 15% rise in electrical output, and a 12 °C reduction in temperature fluctuation. These outcomes highlight the potential of PCM‐integrated PVT panels to improve industrial energy efficiency and support sustainable operations.
