A Study About a Microcontroller-Based Tracking System for Photovoltaic Panels

Abstract A solution for the accomplishment of the tracking system for photovoltaic panels in order to increase the sun generated energy is presented in this work. The two axes of the tracking system are driven by two stepper motors in the suggested approach. The motors are supplied by L298N drivers and controlled by Arduino Mega board, based on the informations provided by light sensors. The sensors measure the intensity of the sunlight, these informations are processed by the ATMega microcontroller and function of these, in order to achieve the highest possible light intensity, the tracking system’s axes will be rotated by the motors. The performances of the tracking system are monitored by Internet of Things concepts.
