Simulation and Performance Analysis of 100 KWp Grid Connected Rooftop Solar Photovoltaic Plant Using PVSYST

The increasing energy demand in developing nations has triggered the requirement of energy security. This has made essential to utilize the potential of renewable energy resources. One of the best alternatives in renewable energy at large scale is grid connected solar photovoltaic systems. Performance evaluation of these grid connected solar PV plant is one of the most important aspect to assess the real-time behavior. Performance analysis could help in designing, operating and maintenance of new grid connected solar photovoltaic (PV) systems. In this study performance evaluation of 100 KWp rooftop solar photovoltaic grid connected power plant commissioned at Poornima University, Jaipur is carried out. In this paper, the solar photovoltaic plant design aspects and its annual performance is elaborated. The various power losses such as losses due to temperature, losses due to internal network, power electronics losses, grid connected losses etc. and performance ratio are also calculated. The performance results of the 100 KWp rooftop solar photovoltaic plant are also compared with the simulation values obtained from PVsyst V 6.39 software. The average final yield (YF) of the solar PV plant ranged from 1.60 to 5.60 h/d, and average performance ratio (PR) of 77.79 % and capacity utilization factor (CUF) of 18.10 % for September 2017 power generation are obtained.
