Solar Tracker system – Amazing Science Project

Project Description:

Our Solar Tracker System is a smart, energy-efficient solution designed to maximize solar energy capture by aligning with the sun’s movement. This system uses an Arduino-controlled servo motor and an LDR (Light Dependent Resistor) sensor to precisely track sunlight, adjusting the panel’s angle throughout the day for optimal exposure. Housed in a durable sunboard structure, this compact and efficient solar tracker is ideal for applications seeking to boost energy output from solar panels, making it a practical choice for residential, educational, and commercial uses.

System Components:

• Arduino Microcontroller: Acts as the control unit, processing data from the LDR sensor and controlling the servo motor.
• LDR Sensor: Light-sensitive resistor that detects sunlight intensity and direction, helping the system determine the sun’s position.
• Servo Motor: Adjusts the angle of the solar panel according to the data received from the Arduino, ensuring optimal orientation.
• Sunboard Frame: Lightweight, durable frame that holds the components in place and provides stability to the system.
• Rechargeable Battery: Powers the system independently, allowing it to operate continuously, even during low-light conditions.
• On/Off Switch: Simple switch for easy control, allowing the system to conserve energy when tracking is not required.

Working Principle:

The Solar Tracker System is designed to harness maximum solar power by automatically adjusting the solar panel’s orientation to follow the sun’s position. The LDR sensor detects changes in sunlight intensity and sends this data to the Arduino. Based on the detected light levels, the Arduino activates the servo motor, which rotates the panel to the optimal angle for capturing sunlight. This continuous real-time tracking boosts solar energy efficiency, delivering greater power generation than static systems.
