Solar energy is the most abundant stream of energy. It is available directly as solar insolation and indirectly as wind energy. Solar energy has the sources of renewable energy. Its potential is 178 Billion MW, which is about 20,000 times the world‘s demand. Sun sends out energy in the form of electromagnetic radiation. In this project we use the solar energy for generation of electrical energy, by using the Solar cells. The solar cells receive the solar energy which is fed to LEDs, maximum intensity of LED indicates maximum solar energy tracked.At present solar electric power generation systems are having fixed solar panels whose efficiency of generation is less. Our aim is to design the system, which will automatically track the sun‘s position and accordingly change the direction of the solar panel in both east to west (longitudinally) and north to south (latitude) to get the maximum output from the solar cell. For this tracking purpose we use a sensor and the input from the sensor is given to the micro controller and according to the program the panel is fixed to the maximum intensity position. Here we are using PIC micro controller. The 16F877A is a low-power, high-performance CMOS 8-bit microcontroller with 4K bytes of Flash Programmable and Erasable Read Only Memory (PEROM).
