A reliability estimate for a roof-top PV during early monsoon in Eastern India

The deployment of Solar Photovoltaic Systems (SPS) is now a predominant activity to achieve the large-scale penetration of Renewable Energy Sources (RES) for access to low cost electric power, both for urban and rural India. In this backdrop an user friendly, reliable and modestly priced PV characterization technique is imperative. This is highly required for the PV industry and also by the consumers and researchers in this area. Thereafter, the reliability analysis of the essential parameters of Poly-Si Solar PV modules during the early monsoon has been initiated in this work. The impacts of clearness index (KT) on the performance parameters have been critically examined. Studies show that, even during the monsoon in this tropical zone, the Poly-Si modules maintain a steady performance with respect to their estimated electrical parameters. Work is currently in progress to extend the deployment of this new metrological practice to available modules of higher wattages in various other seasons.
