Arduino Uno based Maximum Power Point Tracking System by the Optimization of Solar Energy

The title of this work is “Arduino Uno Based Maximum Power Point Tracking System by the optimization of solar energy”. This paper’s objective is to have a solar panel outputting its maximum possible power throughout; this occurs when the panel tracks the sun and rotates accordingly, to receive sunlight to the fullest extent always during the day time. This movement is achieved by installing a couple of servo motor switch the solar panel that changes its direction according to the positioning of the sun. There are basically three major parts of this project, sensor, Arduino Uno and two servo motors. Arduino Uno consists of ATmega328 microcontrollers. ATmega328 microcontroller receives sensor output signal and controls servo motors according to the assigned program. One servo motor is used horizontally to move the panel upward and downward. The other is used vertically from left to right direction. As the solar panel is connected in servo motor so the position of solar panel is same to the servo motor. Since the maximum solar ray is fallen down on the solar panel module so it can achieve maximum power output.
