A system has been designed that adjusts its angle using four servo motors, pulling chains attached to the four corners of the base on which the solar panel is located. The solar panel is attached to the top of the panel, and four sensors are placed next to it that measure the intensity of light. The sensors send information to the Arduino microcontroller, which is located on the bottom panel. Based on this information, the Arduino controls the servo motors using a complex algorithm that allows simultaneous control of all motors. In this way, the height is adjusted to all four corners of the panel. This tilts the solar panel to the optimal position for maximum use of solar energy, thereby increasing the efficiency of the system. In addition, the system uses springs and hinges that ensure the stability and flexibility of the structure, which allows for better stability and adjustment of the position of the solar panel.
