Several factors that lead to long-term degradation of photovoltaic (PV) systems can be identified early in the system operation by a routine on-site visual inspection alongside performance monitoring. This paper discusses the importance of the visual inspection, describes some of the tests conducted and illustrates them with results from an existing PV test platform in Kanpur, India
