Abstract
High temperature is one the important factor that degrades efficiency of Photovoltaic Panels. For every degree increase in the PV temperature, the efficiency decreases by 0.45-0.65%. The Enhancement of performance of flexible PV panel using passive cooling Technique is the main goal of this study. The research aims to optimize the power conversion efficiency of flexible PV panels which are highly affected due to direct contact of mounting surface making them overheat, resulting in decreased output and lifespan. In the present study, two Identical Flexible PV panels 6W each were tested at optimum tilt angle of 31o in atmospheric condition in hot and dry climate of Jodhpur (26.2697°N,73.0352°E), India. Here different electrical parameters of passively cooled panel using Nanomaterial based heat resistant coating were compared with those of a reference panel that lacked cooling. Also, temperature variations over the PV modules were meticulously recorded during August, September, and October using temperature sensors, while considering influencing factors such as wind speed and solar irradiation. According to Experimentation’s finding, a temperature reduction of 6-7°C and an improved solar power efficiency of 2.5-4 % were observed for cooled flexible solar panel.
