Energy efficiency of photovoltaic solar plant in real climate conditions in Banja Luka

Abstract

In this paper comparison of experimentally obtained results of energy efficiency of photovoltaic solar plant of 2.08 kWp installed on the roof of the ASARS in Banja Luka in the real climate conditions in 2013 and 2014 are given. It was found that energy efficiency of photovoltaic solar plant from April till November 2013 was 12.28%, and in same period in 2014 was 13.03%. Also, it was found that the increase in the ambient temperature by 1 °C, photovoltaic solar plant efficiency decreases by 0.43% from April till November 2013, and by 0.27% in the same period in 2014.
