Abstract

The effect of nanoparticles (SiC) with water as its base fluid on the electrical and thermal performance of a photovoltaic thermal (PVT) collector equipped with jet impingement has been investigated. A PVT collector was tested indoor at set levels of solar irradiances and mass flow rates. The system consists of four parallel tubes and 36 nozzles that directly inject the fluid to the back of the PVT collector. The electrical performance of the PVT collector was determined based on the mean temperature of the PVT absorber plate. The SiC/water nanofluid system reported the highest electrical and thermal efficiency. The electrical, thermal, and combined photovoltaic thermal efficiencies were 12.75%, 85%, and 97.75%, respectively, at a solar irradiance of 1000 W/m2 and flow rate of 0.167 kg/s and ambient temperature of about 30°C. Moreover, the Pmax of PVT with SiC nanofluid increased by 62.5% compared to the conventional PV module.
