Monitoring and improvement of PV panel efficiency due to thermal effect

Abstract

Solar Photovoltaic (PV) panels are extensively employed for the purpose of converting renewable energy, namely solar energy, into electrical energy. A significant portion of the solar radiation collected by Photovoltaic (PV) panels is transformed into thermal energy, resulting in the heating of PV cells and a consequent reduction in PV efficiency. The increase in the temperature of Photovoltaic (PV) panels leads to a decrease in their conversion efficiency. The data indicate that an increase of one degree Celsius in PV temperature can lead to a reduction in efficiency of up to 0.65%. This phenomenon has garnered significant scholarly interest in the realm of reducing and managing Photovoltaic (PV) temperature. One of the ways that has been explored is the use of Phase Change Material (PCM), which has the ability to effectively regulate the temperature of Photovoltaic (PV) systems due to its latent heat storing capabilities. Additionally, integrating Phase Change Material (PCM) in Photovoltaic (PV) systems not only helps in temperature regulation but also contributes to extending the lifespan of PV panels by mitigating thermal stress. As the demand for sustainable energy solutions continues to grow, optimizing the efficiency and durability of solar technologies remains a crucial focus for researchers and industry professionals alike.
