SOLAR RADIATION ATLAS IN NORTHERN PART OF THE REPUBLIC OF SRPSKA

The paper presents an atlas of solar radiation for the northern part of the Republic of Srpska formed by PVGIS estimation utility. The atlas contains the results of calculating global solar radiation falling on the optimally placed surface in several cities located in the northern part of the Republic of Srpska (Bijeljina, Šamac, Derventa, Gradiška and Novi Grad) in the period from 2007 to 2016. In addition, the intensity of global, direct and diffuse solar radiation falling on the optimally placed surface in the northern part of the Republic of Srpska is given by months. The basic characteristics of fixed, one-axis and dual-axis tracking PV solar power plants power of 1 MWp and the amount of electricity that can be generated by them in the northern part of the Republic of Srpska, are also given. It was found that with the one-axis tracking solar power plant 27.97-29.36% more electricity can be generated, and with the dual-axis tracking solar power plant 30.80-32.32% more electricity can be generated as compared to the fixed solar power plant.
