ABSTRACT

The solar energy may be used to produce electricity using photovoltaic (PV) modules by a photovoltaic conversion. Among several factors that influence the conversion efficiency of a photovoltaic solar system is to use optimum orientation (tilt angle) of a photovoltaic module. In this work, the measurements of the optimum tilt angles are daily studied during one complete year 2007. Data treatment and analysis are carried out. The results are discussed and the optimum tilt angles of photovoltaic module for the electric power generation at LAUTECH, Ogbomoso area are determined. The maximum output power at an angle 8 degree and 12 degree for dry season (February to April) and rainy season (June to September) respectively were obtained. The results can then be used as a baseline data for the optimal utilization of a P.V module system for the electric power generation in the area of study and other areas having similar radiation characteristics.  

Keywords: solar energy, power output, tilt angle, electricity.
