Photovoltaic solar plants in the Republic of Srpska - current state and perspectives

This paper focuses on the current state and perspectives of the application of PV solar plants in the Republic of Srpska. Further, the paper provides information on the PV application in Europe, geographical position, solar potential and Renewable Sources of Energy (RSE) legislative in the Republic of Srpska. Special attention is drawn to a 2.08 kWp PV solar plant installed on the building of the Academy of Sciences and Arts of the Republic of Srpska (ASARS) in Banja Luka. Experimental results obtained researching the influence of the climate conditions on the performance characteristics of PV plant on the ASARS building in Banja Luka in 2014 are given as well. It was found that the annual mean value of the energy efficiency of PV plant on the ASARS building in Banja Luka was 14.77% and that with the increase of the ambient temperature it decreased. The annual mean value of the performance ratio of PV plant was 95.9%, of the capacity factor 11.7% and of the specific yield factor 84.57 kWh/kWp. The presented results can be useful for the people working on the theory, planning, constructing, design and/or application of the PV based electricity generation systems in the Republic of Srpska.
