Photovoltaics, Solar panel degradation, IV curve, Visual inspection, fill factor, module temperature.
The extensive growth has seen in PV manufacturing industry and installed capacity of solar power plants in the last few years. Hence, the investors seek reassurance of their investments by the long-term performance of PV power plants. The main goal of this work is to study of the PV module degradation under the open circuit and close circuit condition in central India region. For the analysis the two methods i.e. IV curve and visual inspection has been carried out. The experimental analysis has been carried out to asses the degradation of solar panel performance. There is significant decrement in solar panel in terms of maximum power, short circuit current, voltage, efficiency and fill factor has been observed and demonstrated.
