In this study computer software PVS2000 will be used for energy analysis. With the simulation program PVS it has a powerful instrument to plan and dimension grid — connected. With the program, the user is able to compute the PV energy output, characterize and evaluate the operation of the system, compare different variants of the system or optimize system parameters such as the tilt angle or the battery capacity. In developing the program special emphasis was put on ease of use, a clear and comprehensive display of the results, as well as short computation time. A time step procedure that represents the performance of a PV system correctly has been chosen for the simulation program PVS. It offers sufficient flexibility to treat special systems. The system behavior is simulated by balancing the calculated hourly energy flows. By this study only the energy produced from the PV system is needed to be known. The main initial inputs are:

— PV generator capacity 350 kWp and other PV module characteristics

— Inverter capacity 350 kW and other inverter characteristics

— Weather data (solar radiation, temperature)

— Install condition as follow the previous scenarios
