Sun Position Tracking in Solar Panel

This project will discuss on the design of a prototype which has a two axis of freedom in
a solar tracker. An Arduino Uno microcontroller is used for this project as a control
circuit based on ATMega328P. The microcontroller is programmed to assist and navigate
solar panel to be exposed to maximum light intensity by moving the two micro servo
motors with the assistance of four light-dependent resistors (LDR). It is better to use
servo motors as it is more efficient with efficiencies in the range of 80-90%. Besides, it
can maintain its torque at high speed compared to other motors. They can supply almost
twice their rated torque for short period of time and they do not cause much noise or
suffer resonance issues. Therefore, the servo motors will navigate the solar panel towards
the position where there is high intensity of light while it will remain in a static position if
it is in a dark area.
