The application of solar PV has tremendously increased in recent years owing to the improved efficiency and economic feasibility. Among the several applications of PV panels Building integrated photovoltaics has become a hot topic in research. However improper thermal management of solar panels is the main cause of a decline in efficiency and longevity. In this regard, water-based coolingsystems, integrating cooling ducts, using optical filters, phase change materials, and air-passed cooling systems are some of the major techniques for boosting efficiency. This project focuses on upgrading the water-based back surface cooling system to increase the BIPV system's effectiveness by implementinga cooling channel on the back side of the 36-celled 70 W Photovoltaic panel. The project determines the back surface temperature of the solar panel and also the heat extraction rate by the newly designed cooling channel. The parameter considered for analysis was water velocity in the cooling channel ranging from 0.5 m/s to 3.5 m/s. The simulation results revealed that back surface temperature increases up to 326.186 K and a maximum heat extraction of 95674.75 J/s was possible at 3.5 m/s water velocity, accompanied with a 7763.06 Pa of pressure drop inside the channel.
