Analysis of 80KW Grid Connected Rooftop Solar Power Plant using SISIFO

In grid connected rooftop solar PV system, the available rooftop area on buildings is used for setting up solar power plant. The DC power generated from solar photovoltaic (SPV) cells is converted to AC power by solar grid inverter, and is fed to the grid during day time. In night, when solar power is not sufficient, loads are served by drawing power from grid. In this paper, real time and Simulation analysis of 80KW solar photovoltaic roof top grid connected power plant at St. Peter's Engineering College, Hyderabad city is carried out using SISIFO PV simulation software. The real time meter readings of import side and export side of energy are recorded. The real time 80KW solar power plant at St. Peter's Engineering College, Hyderabad generates 401.6KWh per day and simulation results of DC energy output of PV module and AC energy output of inverter are presented. The DC wiring losses and performance ratio are calculated using SISIFO PV simulation software. The DC energy output of PV array is 161232.67Kwh/year and AC energy output of inverter is 153128.45 KWh/year.
