Abstract

Photovoltaic (PV) modules are used for generating electricity in PV power system. Solar light is converted directly into electricity with modules consisting of many PV solar cells. It is important to monitor the behaviour of PV modules under real field conditions to evaluate its tangible performance for a given site. The paper examines the PV module’s performance for nine months of a year in an educational institute premise. Current-voltage and power-voltage characteristics, temperature dependence of the module, fill factor and efficiency analysis for different months have been explored. Normalised performance indices based on measured data have been investigated. Measured results have been compared with the estimated values by means of error statistics. It has been chronicled that peak solar power density reaches 971.04 W/m2 while maximum PV power of 116 W/m2 is produced during the characteristic day at noon. Working efficiency is achieved 9 – 11% during sun shine hours. Average monthly production factor is found to be 89.45%.
