Abstract

A solar photo voltaic thermal (PV/T) system is considered, PV/T is a system of integrating photovoltaic cell and thermal collector in a single equipment. There is a drop in electrical efficiency with respect to increasing in temperature of photovoltaic (PV) module. There will be 0.5% efficiency drop for every 1°c raise after reaching the maximum allowable temperature. In order to overcome this drop in efficiency the temperature of PV panel will be reduced by cooling the PV panel with help of working fluid (water + methanol). A PV module of 0.35m x 0.15m is considered for investigation. The absorber collecting plate is made up of pure copper. The copper tube of cross-section of circular tube with 10mm and 12mm of inner and outer diameter respectively is considered. The length of tube is 3.85.a theoretical model was developed and solved to obtain the overall heat gain and over all combined efficiency of PV module by energy balance equation. The results obtained from theoretical module shows that over all heat gain and maximum thermal efficiency obtained by using (water + methanol) is more than conventional based fluid. The maximum thermal efficiency and maximum electrical efficiency was obtained.
