Abstract :

With the increasing demand for renewable energy, solar power has become one of the most efficient and widely used energy sources. However, fixed solar panels often suffer from reduced efficiency due to their static orientation, limiting their ability to capture maximum sunlight throughout the day. This project proposes an IoTbased solar tracking system that dynamically adjusts the position of a solar panel to optimize energy absorption. The system utilizes Light Dependent Resistors (LDRs) to detect sunlight intensity and an Arduino microcontroller to control a servo/stepper motor for automatic panel alignment. The collected data, including sunlight intensity, panel angle, and energy output, is transmitted to a cloud-based monitoring platform for remote tracking and analysis. This real-time monitoring enables users to optimize performance and detect faults efficiently. The proposed system enhances power generation efficiency, reduces energy losses, and ensures a cost-effective and sustainable renewable energy solution for various applications.
