The parallel advancements in technology in the energy sector, the role of renewable energy sources in energy production is increasing day by day. This growth has particularly drawn attention to solar energy power plants in both the world and our country in recent years. Within the scope of this study, a simulation study was conducted on the Palma solar energy power plant (Palma GES) located in Ağrı province using the PVsyst and PVGIS software. A simulation study was performed to investigate the parameters affecting the power plant's energy generation. The SARAH-1 meteorological database was utilized in the PVsyst simulation, while the SARAH-2 meteorological database was employed in PVGIS. The proximity of these databases to the GEPA values was analyzed. The obtained electricity generation values from the simulation studies were compared with the actual generation values of the power plant. Due to the variations in meteorological databases used in the simulation programs and the extent of their software, differences in electricity generation values were observed. Additionally, when comparing the simulation programs, the PVsyst software produced more detailed and analytical result reports. As a result of the study, it was observed that the PVsyst values were 4.3% higher than the actual power plant generation values, while the PVGIS generation result was 2.3% lower.
