Solar energy is among the sustainable and renewable energy sources that has become an important and inevitable part of our lives today. It is of great importance to consider economic, environmental, and social factors in determining the installation locations of solar power plants (SPP). In this study, we aimed to determine suitable areas where SPP can be established in Safranbolu District by using the fuzzy analytical hierarchy process (FAHP), which is one of the multiple criteria decision making (MCDM) method together with Geographic Information Systems (GIS), to enable the decision-makers to express their preferences in approximate or adaptable ways. The criteria addressed in the technical analysis process were also determined by supporting the basic principles of impact assessment systems. Within the scope of the environmental analysis, the relevant national and international legal frameworks were also examined and the legal constraints were identified. Thus, in the process of determining the optimal areas for SPP, it has been attempted to produce sustainable solutions that are expected to have minimal impact on the integrity of the natural system. This study was carried on within a scientific, technical, and legal framework. According to the results obtained, the Safranbolu District had low, medium, and high sensitivity properties for SPP construction, and the areas suitable for SPP construction provided medium and high sensitivity of 10.86% and 27.26% correspondence detected according to the Chang (Eur J Oper Res 95(3): 649-655, 1996) and Buckley (Fuzzy Set Syst 17(3): 233-247, 1985) methods, respectively. There are very suitable areas for SPP installations in the central and western parts of Safranbolu District, and there are also areas suitable for SPP installation in the northern and southern parts of the district. Thanks to this study, suitable SPP establishment areas were determined for the under protection in a location in Safranbolu where clean energy is needed. It was also observed that these areas do not conflict with the basic principles of impact assessment systems.
