The performance and deterioration of solar photovoltaic cells are significantly influenced by the temperature of the solar cell. Numerous academics and manufacturers have studied the relationship between solar cell temperature and photovoltaic module efficiency. The merging of solar photovoltaic and solar thermal is attempted in this study. The study has been focused on developing an optical filter that uses water as an optical filter to integrate solar photovoltaic modules with solar thermal systems. The system has undergone research and fabrication. In compared to a single solar module, the PV/T system has a better efficiency and lower photovoltaic module temperature. The input temperature, ambient temperature, solar radiation, relative humidity, wind speed, flow rate, and other factors all affect how efficient a PV/T system is. The research has chosen input temperature, solar radiation, and ambient temperature out of a variety of characteristics. In order to prevent hot spots on the photovoltaic module, the research of concentrating PV/T system with water-based optical filter for the concentration of solar rays V-trough has been employed in this work
