In this project , solar panel is rotated in proper direction to get maximum light intensity from the sun. The LDR sensors monitor light intensity. The proposed tracking system tracks sunlight more effectively by providing panel rotation in two different axes. In dual-axis tracking system optimum power is achieved by tracking the sun in all four directions. We are using two dc motors to rotate panel in horizontal and vertical orientation. The dc motors are intefaced through L293d motor driver. The microcontroller used here is Atmega328 from AVR family. The light intensity is monitored using four LDR sensors arranged at four corners of solar panel. The status is displayed on a 16×2 LCD interfaced to the microcontroller.
