Solar energy with solar tracking, will become possible to generate more energy since the solar panel depends on the sun. Even though the initial cost of setting up the tracking system is considerably high, there are cheaper options that have been proposed over time. Light Dependent Resistors (LDRs) are used for sunlight detection. The control circuit is ATMega 328P microcontroller. The solar panel is positioned where it is able to receive maximum light. As compared to other motors, the servo motors are able to maintain their torque at high speed. They are also more efficient with efficiencies in the range of 80-90%. Most of the panels still operate at less than 40%. One of the ways to increase the efficiency of solar panels while reducing costs is to use tracking. Through tracking, there will be increased exposure of the panel to the sun, making it increased power output. The trackers can either be dual or single axis trackers. Dual trackers are more efficient because they track sunlight from both axes
