Abstract Many forms of energy are used in daily life. The most needed of these different forms is electricity. If this energy continues to be met with limited resources, it is clearly seen that sufficient energy needs will not be met in the future. Therefore, in the generation of electrical energy, existing resources must be used extremely efficiently. With the development of technology, electrical energy production is carried out more efficiently with non-renewable energy sources. These technological developments, which come to a certain point, can meet the demanded energy need up to a certain level. For this reason, many studies are carried out on renewable energy sources in order to respond to the needed energy demands. Therefore, in this study, the effect of geographical conditions on panel efficiency in electricity generation with solar panels, which is one of the renewable energy sources, was analyzed. Analyzes were carried out with power plant models installed in four different geographical regions of Turkey using the design and simulation software for photovoltaic systems program for PV systems. The effects of latitude, altitude and temperature on electrical energy production were investigated using the established power plant models.
