Harness the Sun’s Power with Your Own Arduino Solar Tracker – Single Axis LDR Kit

Every part needed, pre-tested for compatibility, with an AI build companion trained on this exact project. Shipped from Bengaluru in 3-5 days.

Turn a small solar panel into an intelligent sun-chasing system. This kit uses two light-dependent resistors (LDRs) split by a central divider to constantly compare light intensity, driving a motor that tilts your panel toward the brightest part of the sky. It’s a hands-on way to explore how real-world solar farms boost energy output by up to 30% daily through active tracking.

What You'll Build

You’ll assemble a functional single-axis solar tracker that moves a panel mount from east to west, following the sun’s path. The Arduino reads LDR differentials and commands the L298N motor driver to rotate until both sensors are equally illuminated. Once built, you can run it off a 9V battery and watch it actively hunt for peak light.

What You'll Learn

• Wiring LDR voltage dividers and reading analogue values with Arduino
• Programming conditional motor control logic (if-else) for dual-sensor comparison
• Interfacing the L298N motor driver for bidirectional DC motor movement
• Understanding solar geometry and the principle of maximum power point tracking in renewable energy
