Keywords:
PV/PVT, Nano-enhance PCM, Nanofluid.Abstract
The present study provides a thorough experimental investigation into the performance improvement of photovoltaic thermal (solar panels) systems in the presence of dust accumulation, utilizing various thermal management strategies. five systems were investigated: a monocrystalline solar panel, a standalone photovoltaic panel, a water-cooled PV/T system, a PV/T system integrated with phase change material, and a PV/T system that integrates nano-enhanced phase transition material and silicon carbide (sic) nanofluid. The electrical power output, thermal efficiency, and overall performance were evaluated under both clean and dust-covered conditions through the execution of experiments at flow rates spanning from 5 to 10 lpm. According to the findings, the PV/T-nephase transition material-nanofluid system obtained the highest overall efficiency of 84.12% at 7 lpm. It exhibited superior temperature reduction, with the solar panels surface temperature decreasing by up to 62%. Electrical efficiency was enhanced by 2.5% when compared with conventional water-based systems. at a rate of 7 lpm, dust accumulation resulted in a 3.62% decrease in electrical efficiency and a reduced electrical power output of up to 57.36 w. these findings emphasize the efficacy of incorporating nephase transition material and nanofluids in reducing temperature-related losses and enhancing system performance, even in hazy conditions that are common in semi-arid regions such as india.
