Abstract: This study simulates the performance of a 21 kW grid-connected photovoltaic (PV) power plant under climate conditions in Tabriz and Ahvaz cities, Iran. The impact of ambient temperature, dust accumulation, and incident solar radiation on the output power of the PV plant, performance ratio, various losses, and CO₂ emission reductions was investigated. The results showed that the power output of the system was 34.82 MWh/year and 35.27 MWh/year in Ahvaz and Tabriz, respectively. Furthermore, the annual performance ratio of the PV system in Ahvaz was 78.1% while this value was 85.8% for the plant in Tabriz. The PV plant losses due to temperature were also obtained to be 12.94% in Ahvaz and 6.45% in Tabriz. It was found that the development of such solar power plants in Ahvaz and Tabriz can save 15.406 and 16.117 tCO₂/year, respectively. The simulation results can be applied to future large-scale PV plants.
