Solar Tracker Science Project Components & DIY Kits in Bangladesh

Building an automatic solar tracker science project is one of the most effective ways for school, college, and university students in Bangladesh to learn embedded robotics, renewable energy dynamics, and automated sensing. A solar tracking system automatically rotates a solar panel toward direct sunlight using light-dependent sensors and servo motors, delivering up to 30% to 40% higher efficiency than fixed panels. At Biggan Project (বিজ্ঞান প্রজেক্ট), we provide a complete, verified collection of individual components, structured DIY kits, and custom mounting hardware designed specifically for science fair exhibitions, academic semester projects, and hobby electronics.

What is a Solar Tracker and How Does It Work?

A solar tracker is an electro-mechanical device that aligns a photovoltaic (PV) solar panel perpendicular to the sun's rays throughout the day. In student science projects, the system typically relies on two or four Light Dependent Resistor (LDR) sensor modules separated by an opaque cross-barrier. When sunlight shifts, an imbalance in resistance is detected by a microcontroller—such as an Arduino Uno, Nano, or ESP32. The controller processes these analog values via an algorithmic loop and signals micro servo motors (such as SG90 or MG990S) or stepper motors to reorient the panel until light intensity equalizes across all sensor probes.

Frequently Asked Questions (FAQ)

Can I make an automatic solar tracker without an Arduino or microcontroller?

Yes. Students can build a basic analog solar tracker using an LM358 operational amplifier comparator IC, two LDRs, and a bi-directional DC motor driver circuit or transistor H-bridge. This setup is great for demonstrating fundamental electronics without writing code.

How do I power both the Arduino and the servo motors safely?

Servo motors draw peak current bursts that can trigger an Arduino board brownout reset if powered directly from the 5V microcontroller pin. It is recommended to supply the servo motors using an external 5V 2A power adapter or an 18650 battery paired with an LM2596 step-down buck module, keeping a common ground (GND) connection with the microcontroller.

What programming library is used for an Arduino solar tracker?

You can use the built-in Arduino Servo.h library to drive the positioning motors, while standard analogRead() commands monitor sensor feedback from the LDR pins.
