Geo-Environmental Analysis on Specifying Solar Energy Power Plant (SEPP) Fields by GIS and Different Fuzzy AHP Methods

Abstract

The use of solar energy among renewable energy sources has started to become widespread due to its potential, the practicality of use and environmental friendliness. In assessing the installation sites of solar energy power plants (SEPPs) economic, social and environmental elements should be taken into consideration, and cultural and paleontological heritage areas should not be damaged. In order for decisionmakers to show their own predilections in some ways, the subject of this research is to specify the convenient fields for SEPP installation in Yalova province with all its districts using different methods of fuzzy analytical hierarchy processes (FAHP) together with Geographic Information Systems (GIS). Buckley (1985) found that the geometric mean approach achieved an accuracy rate of 24.99% for the combination of high and medium susceptibility levels. On the other hand, using the extent analysis method proposed by Chang (1996), an accuracy rate of 7.82% was obtained. The results indicate that the Geometric mean approach by Buckley (1985) provides more realistic results compared to the extent analysis method by Chang (1996). According to the results obtained, it has been seen that Yalova province has convenient fields for SEPP sites in the center and east, including the Central and Çiftlikköy districts.
