Abstract

The Solar energy is a globally prominent renewable resource, particularly in regions like ADRAR, South Algeria, which experiences high irradiation (around 5.8 kWh/m2). The efficiency of photovoltaic (PV) systems is often limited by their non-linear electrical characteristics and high operating temperatures. This study investigates the effectiveness of an integrated Photovoltaic/Thermal (PV/T) system combining concentrator Bi-reflector to increase solar flux and a plate heat exchanger for active cooling and heat recovery. Experiments conducted under real-world ADRAR conditions demonstrated that the Bi-reflectors enhanced illumination while the cooling system absorbed excess heat. This dual approach successfully maintains electrical efficiency by keeping the panel temperature low and simultaneously provides a useful thermal output (heated water). The results conclusively show that the integrated Bi-reflector and heat exchanger system significantly increases the overall electrical and thermal performance of the PV generator, representing a promising strategy for optimizing PV energy generation and developing efficient PV/T systems in high-irradiance desert environments.
