Abstract:
In commercial Photovoltaic (PV) deployment, solar modules are connected in series with the bypass diodes across each module to reduce the effect of shading on PV modules. Shading results in the creation of localized heating called hotspots it affects both short-term in form of power output reduction and long-term performance as the reliability of PV system, but still, there is no standard procedure to tell whether a PV module or a PV string has hotspots or not. We like to focus on the above issue where we have effectively analyzed thermal, visual and electrical data Of PV modules of Silicon technology namely Mono-crystalline and Poly-crystalline PERC and PERC plus to formed a standardized real-time procedure to tell whether a PV module has hotpot defects or not. The results can be extended to the big running power plant also. A MATLAB based code is developed to convert the thermal IR image effectively to detect the location of the hotspots by giving the exact temperature and the image pixels value to the information data. Our main focus is on mono-crystalline and poly-crystalline PV modules as it is easily viable for the consumers.
