Solar panels are increasingly popular for converting solar energy into electricity. They can operate as stand-alone systems or connect to the grid. Earth receives 84 Terawatts of solar power daily, while we consume 12 Terawatts. To maximize solar-to-electrical energy conversion, panels need to be positioned perpendicularly to the sun. This project aims to design an automatic tracking system that locates the sun’s position and adjusts the solar panel accordingly. It utilizes photoresistors as sensors and comprises a light-sensing system, an Arduino microcontroller, gear motors, and the solar panel. The system is expected to boost energy output by up to 40% compared to static panels. The key component is the light-dependent resistor (LDR) connected to the Arduino, which continuously tracks the sun. Two servo motors reposition the solar panel in real-time to keep it facing the sun. This innovation offers an efficient and sustainable solution for meeting our increasing energy demands.
