Solar Tracker Efficiency Study Kit with Arduino Uno + LDR
Solar Tracker Efficiency Study Kit — Build a Dual-Axis Sun Tracker, Measure Power Gains with Arduino Uno
Every part needed, pre-tested for compatibility, with an AI build companion trained on this exact project. Shipped from Bengaluru in 3-5 days.
What if a single-axis solar panel could produce up to 30% more energy just by following the sun? In this kit, you’ll build a dual-axis tracker with four LDR sensors and servo motors, then use an INA219 precision current sensor to measure exactly how much more power the tracking panel delivers compared to a fixed orientation. It’s a data-driven STEM project designed for students who want to go beyond theory and see renewable energy efficiency numbers firsthand.
What You'll Build
A working solar tracker that keeps a 6V panel perpendicular to the light source, along with a side-by-side measurement setup for fixed vs. tracking comparison on the OLED. You’ll see real-time power output in watts and can graph tracking efficiency gains—perfect for physics labs and science fairs.
What You'll Learn
- Arduino sensor integration: LDR light sensors, INA219 over I2C, and servo motor control
- Closed-loop control algorithm for sun tracking using differential LDR readings
- Power measurement with a precision current/voltage sensor and calculating efficiency ratios
- Data logging and live comparison on an OLED display to quantify tracking benefits

Who This Kit Is For
Ideal for CBSE Class 11–12 students working on physics investigatory projects, B.Tech first-year ECE/EEE students prototyping a renewable energy mini project, ATL Tinkering Lab mentors, and teams at Smart India Hackathon 2024 exploring solar optimization solutions. Everything is plug-and-play — no soldering required.
Built and Backed by Compoden
Every Compoden kit ships with an AI build companion trained on this exact project — accessible via a QR code on the box, with WhatsApp and email backup. We've spent 10 years building projects for makers, schools, and institutions across India. If a part fails because of a manufacturing defect, replace it free within 7 days.
What if I get stuck during the build?
Your kit includes a QR code to an AI companion trained on this exact project; it can debug wiring, suggest code changes, and guide you step-by-step. Direct WhatsApp support is also available.
Do I need to solder?
No soldering — the kit uses a breadboard and jumper wires. All connections are plug-and-play.
Can I use this for a school science fair or CBSE project?
Absolutely. The comparative efficiency data produced by the INA219 satisfies CBSE Class 12 physics investigatory project requirements and makes an impressive science fair display.
How accurate is the INA219 power measurement?
The INA219 measures voltage and current with 1% accuracy, giving reliable power readings for comparing tracking vs fixed performance.
LDR quad drives servo to track light. INA219 compares power of tracking vs fixed panel.
