Arduino Based Solar Tracker

Working Principle

Detection of Sunlight

The light sensors (LDRs) detect the intensity of sunlight from various directions. Each LDR provides an analog signal to the Arduino based on the amount of light it receives.

Signal Processing

The Arduino reads the analog signals from the LDRs. It compares the signals to determine which direction has the highest light intensity.

Decision Making

Based on the comparison, the Arduino decides how to move the solar panel. For example, if the east-facing sensor detects more light than the west-facing sensor, the Arduino will command the motors to move the panel eastward

Panel Adjustment

The Arduino sends signals to the servo or stepper motors to adjust the solar panel’s position. In a single-axis tracker, the panel moves either horizontally or vertically. In a dual-axis tracker, the panel can move in both directions to track the sun’s path more precisely.

Continuous Adjustment

This process of detection, signal processing, decision making, and adjustment continues throughout the day. The solar tracker constantly aligns the solar panel to face the sun directly, optimizing energy capture.
