This paper focuses on the identifi cation and analysis of terrain suitability for the installation of solar power plants within the territory of the Municipality of Priboj, using a multicriteria decision-making approach (GIS-BWM) based on Geographic Information Systems (GIS) and the Best-Worst Method (BWM). The research encompasses the analysis and evaluation of both natural and anthropogenic conditions within the selected local administrative unit. The applied methodological framework enables the identifi cation of the most suitable areas for the construction of solar facilities through the assessment of six criteria: aspect, slope, land use, distance from settlements, transportation infrastructure, and watercourses. Using the BWM, locations with the highest energy potential were identifi ed. The obtained results were classifi ed into fi ve suitability classes, depending on the degree of terrain appropriateness for photovoltaic panel installation. Given that the territory of the Municipality of Priboj is characterized by a relatively low amount of global horizontal irradiance, the results indicate that the majority of the area (57%) exhibits low suitability for solar panel installation, while as much as 11% of the municipal territory is completely unsuitable. The key fi nding of the study lies in the identifi cation of optimal locations covering only 10.1 km² (2%) of the total area, which meet all criteria for installation. The most signifi cant spatial potentials were identifi ed in the settlements of Krnjača, Kasidoli, Pribojska Goleša, and Pribojske Čelice. The results provide a precise basis for strategic spatial planning and the implementation of solar energy as a sustainable energy source within the Municipality of Priboj.

This paper investigates the assessment and mapping of the spatial potential of the Pljevlja Municipality for the construction of photovoltaic solar power plants. This is of particular environmental and economic importance for this area, as it has traditionally always relied on coal exploitation. The methodological approach is based on the integration of GIS and multi-criteria analysis through the application of the Best–Worst Method. Key physical geographic and infrastructural criteria were considered: aspect and terrain slope, land use, distance from primary roads, settlements, and major watercourses. Environmentally sensitive and technically unsuitable areas, covering 33.7% of the municipality, were excluded from the analysis, while 47.7% of the territory was classified as low suitability. The results of the synthesis suitability map indicate that the Pljevlja Municipality possesses significant spatial resources for the development of solar power facilities. Specifically, areas with moderate suitability account for 17.4% of the territory, while zones with the optimal highest suitability cover 1.2%. Although the most favourable conditions occur across a relatively small part of the municipality, these areas represent strategically significant zones for photovoltaic development. The combination of high solar irradiation, flat terrain, and proximity to existing road infrastructure reduces overall investment costs. The obtained results and the generated GIS model provide a useful preliminary basis for local governments, spatial planners, and potential investors, enabling informed decision-making in the process of sustainable energy development and the diversification of the energy sector of the Municipality of Pljevlja.
