Hardware implementation of sun tracking solar panel using 8051 micro-controller

The Solar panel consists of a number of Solar cells transforms sun's energy into electrical energy. If the solar panel is continuously aligned along with Sun rotation, higher efficiency may be obtained. In this paper, a solar tracking hardware implementation is proposed which tracks the Sun's movement throughout the day. The affordable solar panel design is based on using 8051 micro-controller, dc motor and light sensor aligned in a simple circuit. The main aim is to enhance the existing solar panel output. The output of the proposed solar tracking panel is found to be 32.17% higher as compared to the static Flat solar panel.
