Power generation through solar photovoltaic has grown at a faster rate in India. The estimated target by 2022 through solar PV rooftop as well ground mounted system is 100 GW. The life of the panel is 20 years. Many researchers have focused on increasing power output as well as panel size optimisation. The literature shows that the panel degrades 1% of the rated power every year. However, limited study is only available for degradation of panel on Indian climatic conditions. Many parameters, like dust, temperature, humidity have a role in the degradation of the panel. The paper has carried out a detailed investigation of the degradation of solar panel which has been put in use for the year 1998, 2007 and 2016. The degradation of power from its rated power has been estimated and reported. Also, thermal imaging of the panels on same operating condition has been recorded.
