The chief objective of this study is the reliability and durability assessment of 4–6-year-old solar photovoltaic (PV) crystalline systems located in the city of Rajkot, Gujarat (having a composite climate condition). These all systems were originally installed during 2010–2012 with a rated capacity of 10 kWp (2 in numbers), 50 kWp (1) and 100 kWp (3) (fixed tilt, south orientation). This study only recognized the degradation and failure mechanisms. The observations obtained from the exclusive visual inspection and thermography made on 6 different solar plants were utilized to detect degradation and failure types. The encapsulant discoloration and delamination, corrosion of cell gridlines, back-sheet delamination and yellowing, snail track, hot spot, cell cracks and burn marks at back-sheet have been examined to be the degradation and/or failure types of these 4–6-year-old solar PV plants in this particular composite climate.
