Abstract :

In this project, we present a solar tracking system designed to maximize energy efficiency by rotating a solar panel based on the sun’s position. The system utilizes Light Dependent Resistors (LDRs) to detect sunlight intensity, allowing the panel to automatically adjust its angle for optimal solar exposure throughout the day. An Arduino microcontroller processes the LDR input and controls a motor driver to rotate the panel, ensuring it continuously faces the strongest light source. The harvested energy is stored in a battery for future use, optimizing power generation. This system enhances energy capture, increases the efficiency of solar panels, and provides a costeffective solution for renewable energy applications.
