JEE_V10_N1_RP3 Rachit Srivastava Vinod Kumar Giri Journal on Electrical Engineering 2230 – 7176 10 1 14 18 PVsyst, Grid Connected Photovoltaic System, Pre-sizing, Optimization Photovoltaic system simulation software is very important in prediction of output electricity from the PV system. In this paper, Grid connected photovoltaic system is simulated using the PVsyst software. In this study, PVsyst software is used to design a grid connected PV system for Madan Mohan Malaviya University of Technology, Gorakhpur in India. The detailed system configuration, system output and system losses are determined in this study. From the previous simulation by the HOMER software, optimal size of the PV system is determined, that is able to supply the electricity to the university throughout the year. It is founded that 2000 PV module and 10 grid connected inverter is the optimal solution for the load of university. About 901.44 Mwh electricity will be available to the grid in a year.
