Technical and Economic Analysis of grid-connected PVsystem Using the Software and a Case Study on a Sample of 5KW Installed

Solar systems that have been built so far in Iran usually do not meet the expected efficiency.Lack of proper efficiency of solar power plants is mainly due to poor design and non-use of softwares available in this field. In this research, a 5KW grid-connected photovoltaic system located in Tehran Power Distribution Company (TehranPars Electricity Distribution Company) has been investigated technically and economically and has been influenced by factors affecting the amount of power plant production and practical solutions for increasing the plant's efficiency.To simulation, design and technical analysis of PV power plant PVsyst software is used.
