This paper deals with arduino based solar tracking system,To grab maximum energy solar is non conventional source of energy with the help of this we developed solar tracking system so that can produced maximum output electricity But due to revolution of earth solar source,Means sun does not phase panel continuously . Hence less electricity produces. To produce the maximum amount of energy a solar panel must be perpendicular to the light source because the sun moves both throughout the day as well as the year a solar panel must be able to track the sun�s movement and maximum possible output power. https://www.ijiert.org/paper-details?paper_id=141172
