Solar energy is the most efficient form of en- ergy ,and used for domestic such as cooking , solar pan- els and for industrial purposes for producing electrici- ty, transportation, solar batteries. So in today’s time usage of solar cells for installing solar panels is consid- ered cardinal. They are installed in the direction of maximum radiation of sunlight. Since the sun keeps moving maximum radiation of sun cannot be obtained during all the time. The maximum radiation receiving position comes once in 24 hours. Sunlight consists of two components, one is the “di- rect beam" which carries the maximum part of solar energy, and the second being “diffuse sunlight" which carriesthe remaining sunlight – the diffuse portion refers to the blue sky on a clear day, and on cloudy days con- sists the larger portion. Since direct beam constitutes majority of energy, to have maximum efficiency the sun needs to be visible to panel utmost. The earth receives 16x1018 units of solar energy every year, which is 20,000 times the requirement of mankind on earth. The function of Solar panels is to convert light energy into electrical energy. Solar power generation system using moving panel is an efficient power generating method using sun radiation. To sense the direction of maximum intensity of light two sensors are used. The difference between the outputs of the sen- sors is then calculated and given to the microcontroller unit. The energy from the direct beam inclines with the cosine of the angle between the incoming light and the panel. And for the angles of incidence up to around 50°the reflectance is constant, beyond which reflectance reduces significantly. Microcontroller processes the input voltage and controls the direction in which the motor has to be ro- tated so that it will receive maximum intensity of light from the sun.
