Solar radiation performance adjusting to PV system

Abstract

The first section of this paper presents the conditions of solar radiation orientation in Kosovo. The sheer existence of the sunlight is indeed an inexhaustible source of renewable energy having ample potential to meet all humankind’s needs for it when innovative technology is used in compliance with modern standards appropriate to economic and social environment and to the nature itself, too. The research conducted for the purpose of the present paper reveals that the greatest amount of radiant energy is focused on the absorber of the collector sensor which transmits the entire moving space at right angles to the sunlight. It is important to note that the collector angle in relation to the horizontal plane cannot be less than 20°, because there is a possibility that the collector, due to the small angle, is covered in dirt and aerosol pollution. These data ensure that best performance in high generation efficiency is reached by improving harnessing patterns in solar cell response. The objective of the Kosovo Plan in 10 years’ period has stimulated the support policy for renewable energy sources, set to be at least 10% at the national level. This paper examines radiation efficiency assessments under sensor monitoring over the absorption space where all time, high absorption power PV system panels are located. Experimental study shows that Kosovo has radiation potential due to its Geographical position equal to 1400kWh, with the optimal sensor orientation angle of 25° in the Gjakova Region. The solar radiation efficiency for one-year period has resulted in increased performance under sensor monitoring during the months of March - September, from 0.89 kWh/m2/y to 0.92 kWh/m2/y, when the equinox provides the longest sunlight intervals.
