In recent years there has been a growing interest in photovoltaic system as renewable energy sources without environmental pollution and excess heating of air. Photovoltaic cells convert the enrgy of sunlight directly into electricity. However, solar radiation varies with changing atomospheric conditions (clouds and dust) and the changing position of a photovoltaic sysytem relative to the sun. In this work, it was intended to enhance the watt-hour efficiency of a solar cell module. A photovoltaic system tracking the azimuthal movement of the Sun was constructed. The system was drived azimuthaly with a geared motor controlled by a solar sensing circuit. And a PIC data logger circuit to accumulate the data of the system power was equiped. It was verified experimentaly that watt-hour effiecy was enhanced 27 [%] by using the the solar tracking type photo voltaic system.
