An EfficientLow Cost Solar Tracker Using Microcontroller

Solar energy is gaining importance day by day as an energy resource. Efficiency of solar panelsystems must be maximized to make solar energy more usable.By sun tracking we can increase the efficiency of solar panel.When the solar panel is perpendicular to the sun's rays it receives more sunlight.This paper is about follow the sunlight direction across the sky by using a DC gear motor, the AT89S52 microcontroller control the movement of gear motor by this the solar panel will change their position, solar panel detects the sunlight using photocells.The objective is to design and implement an automatic solar-tracking mechanism using embedded system design with minimum cost and reliable structure.
