Performance analysis of 1MW grid-connected photovoltaic system for threedifferent environments in southwest Baghdad by using PV-system software

Despite the many solar energy plants that have been installed, the need to study photovoltaic systems using theoretical and practical models still exists due to the large number of variables that affect the productivity and efficiency of solar systems. In this theoretical study, a 1 MW photovoltaic (PV) system was studied in Al-Mu-sayyb city, Al-Razaza Lake, and Ayen Al-tamer desert in southwest Baghdad, using PVsyst V 7.4 software to choose the best location. The input data for the PVsyst are (Geographical site, power of the system, system information, and type of grid). The production of the system in Al-Razaza Lake, Al-Musayyb city, and Ayen Al-tamer desert are 1785 MWh/year, 1885 MWh/year, and 1779 MWh/year respectively. The performance ratios for Al-Razaza Lake, Al-Musayyb City, and Ayen Al-Tamer Desert are 0.817, 0.831, and 0.816. The current system can mitigate the emissions of CO2 for the system in Al-Razaza Lake, Al-Musayyb, and Ayen Al-Tamer desert to 34617 tons,32503 tons, and 32371 tons respectively through 30 years of operation. The lake environment (Floating PV system) is a better location for installing the plant than other sites due to the output energy is higher than in other environments.
