Highlights

  • Degradation rate of large-scale crystalline (c-Si) PV array.

  • Four years performance ratio of c-Si PV array.

  • Energy derate of c-Si PV array under semi-arid climates in India.

Abstract

We report the preliminary results of the degradation study of large-scale photovoltaic (PV) system installed using 1006.74 kWp crystalline silicon (c-Si) PV array. A linear least square (LLS) fitting method is adopted, and the degradation rate (DR) is calculated for the four years based on monitored operational data in semi-arid climates of India.
