OPTIMIZATION OF GLOBAL SOLAR RADIATION OF TILT ANGLE FOR SOLAR PANELS, LOCATION: OUARGLA, ALGERIA

Abstract

The solar photovoltaic energy is a new and an appropriate alternative source, but the low conversion efficiency of the PV arrays and the large area necessitate their optimum use. In this paper, we analyze this problem and we show the importance of the inclination of the solar panels to maximize the efficiency of the system. Four optimization methods (monthly based, seasonal based, bi-annual based and annual based) are implemented. We have computed the maximal energy that can receive a solar panels, by choosing the monthly optimal angle of inclination and have demonstrated that for the considered geographical site this energy remains practically maximal by changing the tilt angle of the panels four times (seasonally) or two times( bi-annual) in a year only.
