Geospatial evaluation of belgrade for the purposes of determination of suitable locations for the construction of PV plants

Abstract

The aim of this paper is to identify the most suitable locations for the construction of Solar Photovoltaic Plants (PVP) on the territory of the City of Belgrade (Republic of Serbia). The city is rich in natural resources and abundant in energy potential. The climatic and spatial characteristics favor the use of solar energy: the average annual solar radiation in Belgrade is 1446.8 kWh/m(2)/year, and the sunshine duration is around 2200 h/year. The analysis covered the area of 3240.7 km(2) (administrative area of Belgrade). Geospatial evaluation was based on three basic criteria: aspect, slope and land use. The Method of elimination in combination with modern methods in geospatial research (GIS) was applied. Based on the mentioned geospatial factors, thematic maps were made and later, their overlapping resulted in obtaining a synthesis Map of the suitability of the terrain for the construction of the PV plants. Of the total considered area, 13.68% were evaluated as suitable for the given purpose.
