SOLAR TRACKING SYSTEM USING AT89C51 MICROCONTROLLER AND LDR

This paper deals with a microcontroller based solar panel tracking system. Solar energy is rapidly gaining notoriety as an important means of expanding renewable energy resources. My project will include the design and construction of a microcontroller - bas ed solar panel tracking system. Solar tracking enable more energy to be generated because the solar panel is always able to maintain a perpendicular to the sun’s rays. Development of solar panel tracking system has been ongoing for several year now. As the sun moves across the sky during the day, it is advantageous to have the solar panel track the sun location, such that the panels are always perpendicular to the solar energy radiated by the sun.
