ENHANCEMENT OF PVT EFFICIENCY, THERMAL ENERGY STORAGE WITH EFFECTIVE PCM SELECTION AND COOLING TECHNIQUES

The electrical efficiency of Photovoltaic(PV) panel decreases with increment of solar panel temperature. The Photo voltaic panel electrical efficiency depends on operating PV panel temperature, its material and its climatic conditions. Hybrid Photo Voltaic panel is the best method to obtain better efficiency with proper panel cooling. In PVT system the solar panel heat was removed with the help of cooling medium behind the solar panel. Thermal control of the PVT hybrid system maintained in a better way by passive cooling method with Phase change material. PCM major draw backs are high nucleation rate, large undercooling low thermal conductivity, and low PCM life cycle. We can enhance the PVT efficiency with proper address of PCM draw backs. PVT-PCM modules proposed for better enhancement in thermal storage potential 35 to 44% than the conservative water PVT system, with prolonged thermal storage accessibility and accelerated outp ut from 7.50 to 14.0 %.The selection criterion of PCM was very significant for enhancement of panel cooling to get the elevated electrical efficiency in PVT-PCM hybrid system. This research paper presents the research gap to find optimum process in cooling methods for PV panel with optimized hybrid model design with better selection of Phase change material, Fin design to increase the best PV panel efficiency by decreasing the temperature of the PV panel at all conditions.
