In this paper, a grid connected solar photovoltaic plant has been proposed, and its performance has been evaluated. The performance analysis has been done on a designed 100kW grid connected solar photovoltaic plant in the Semnan city. The simulated system comprises 625 CIS PV modules. Each PV module has a rating of 160Wp. All the PV modules are arranged in 25 strings, with each string made up of 25 modules in series. Two solar inverters, each having a rating of 50 kW are used for interconnecting with grid. The 100 kW PV system generates 178.99 MWh/year, wich 170.3 MWh/year is injected into the grid. The performance ratio and its total impressed losses have been calculated. The performance ratio of 100KW solar plant in Semnan city obtained 83%. Finally, the simulation results indicate that the designed solar power plant will prevent 171 tons of gas CO2 from being produced during 30 years.
