Solar Tracker Kit

This kit serves one of our pillars: Energy — technology in the service of nature.

Build a solar panel that turns to follow the sun across the sky — just like a sunflower. Two light sensors tell the brain which way is brighter, and a motor rotates the panel to catch the most energy. A real demonstration of how smart solar farms squeeze more power from the sun.

What's inside the kit?

• Arduino Nano 328 CH340 Chip (Clone) — The brain — reads sensors, drives the motor
• LDR Photoresistor Module ×2 — Light sensors (east & west)
• SG90 Micro Servo Motor 180° 1.8 kg.cm Plastic Gears — Rotates the panel toward the sun
• Solar panel 2 Watt - 5v/400mA — The solar panel that catches the energy
• BB-01 Breadboard 830 Tie Point — Build base (full breadboard)
• BB-J140 Connecting Jumper Wires for Breadboard (140 Wire) — Connections (140-wire set)
• Kit Resistor 1/4W - 100 Carbon Resistors 1% Tolerance 1/4W — Resistors for the light-sensor circuit

How the idea works

Every part in the kit has a job. Assembled in the right order they stop being loose parts and become a working system — one you build yourself, understand at every step, and see the result of with your own eyes. The included build guide walks you from zero to running.

Your journey: from kit to competition

• Build — assemble the kit and get it running.
• Understand — learn why each part is there and how it works.
• Improve — modify it, add a sensor, tune it, try your own idea.
• Make a project — turn the experiment into a project that solves a real environmental problem.
• Compete — enter your project into local and international competitions.

A good fit for tracks such as:

• Energy / الطاقة

What you'll learn

• How solar panels convert light into electricity
• How light sensors (LDRs) detect direction
• Programming a servo motor to respond to sensor data
• Why sun-tracking boosts renewable-energy output

Extend & innovate

Add a second axis for full 2D tracking, log the energy gained vs a fixed panel to prove the improvement, and connect it to a battery so it charges devices while it tracks. Scale the idea into a science-fair project on renewable energy.
