It was found that energy efficiency of PV solar plant from April till November 2013 was 12.28%, and in same period in 2014 was 13.03%. Also, it was found that the increase in the ambient temperature by 1°C, PV solar plant efficiency decreases by 0.43% from April till November 2013, and by 0.27% in the same period in 2014.
