For photovoltaic (FV) system designers, the use of simulation programs is very important with the features of the ability to perform detailed analysis that it offers, such as the geographical area where the system installation will be performed, the energy demand and the system reliability parameters can be selected in the most appropriate manner. This study aims to simulate climate data, load requirements and basic system components using PV * SOL, Helioscope, Polysun and PVGIS simulation programs in the simulation environment and visualize the general characteristics of the installed 1MW solar power plant. The data used in simulations is obtained using real-made measurement values and/or reliable databases from national and international sources. Furthermore, the amount of electricity produced by the FV power plant was transferred to the computer environment and the accuracy of the simulation programs was studied by comparing the simulation data of the FV system with the real environment data. When compared the simulation programs, it was observed that the Helioscope program had the lowest error rate in giving the nearest result to real environmental data. In addition, the order of other simulation programs in terms of giving the minimum error rate is PVGIS, Polysun Online and PV * SOL. Thus, it is believed that FV simulation programs could provide more infrastructure for future studies, along with the reduced error rates in the future.
