Solar Tracking System

Dual-Axis Solar Tracking System | Arduino SimpleCircuits Arduino Solar DIY Renewable Energy Project Dual-Axis Solar Tracking System Build a high-performance solar tracker that follows the sun in real-time. Four LDR sensors, an Arduino UNO, and two servo motors — boosting energy capture by up to 40% versus fixed mounts. 40% More Efficient 4 LDR Sensors 2 Servo Axes <300mA Power Draw Finished Build System Overview How the System Works The tracker reads the sky through four LDR sensors placed around the panel, computes intensity deltas, and drives two SG90 servos in a real-time closed loop — keeping the panel perpendicular to sunlight from sunrise to sunset. ...
