Performance of rooftop solar power system under real climatic conditions was studied for a particular day of consideration. The present study covered all three types of Si modules like amorphous (a-Si), mono crystalline (Mono-Si) and poly crystalline (Poly-Si) was compared for their behaviour against change in temperature and irradiance. Different crucial solar module characteristics like efficiency, short circuit current, open circuit voltage and fill factor were scrutinised to find out the temperature coefficient of open circuit voltage of all three technologies. The derived values of temperature coefficients for a-Si, Mono-Si and Poly-Si modules are -0.068, -0.063 and -0.066 V/oC, respectively. Moreover, nature of variation in fill factor (FF) with temperature was studied and maximum change in FF is about 0.18%, 0.25% and 0.5% for a-Si, Mono-Si and Poly-Si, respectively. This study will help end users to opt for an appropriate selection of Si modules based on real climatic conditions on a site of installation.
