Solar Tracker Complete Project with Arduino

Arduino Single Axis Solar Tracking System for Students and Science Projects

The Arduino Single Axis Solar Tracker is a ready-made educational project designed to demonstrate how renewable energy sources can be made more efficient using automation. This smart solar tracking system automatically aligns a solar panel to face the light source, simulating sunlight using a torch or real sun. It is equipped with light-sensitive LDR sensors, a precision MG90S servo motor, and powered by 18650 Li-ion batteries. The intelligent system is controlled using an Arduino Uno SMD R3 microcontroller. Ideal for school, college, or university students participating in science fairs, this project provides a hands-on learning experience in electronics, automation, and renewable energy technology. Offered by Bigyan Project (বিজ্ঞান প্রজেক্ট), this solution is not just educational but also future-focused, making it a valuable tool in STEM learning.

Frequently Asked Questions (FAQs)

• Q: Is the project fully assembled? A: Yes, this is a complete, ready-to-use project. No assembly is required.
• Q: Can it work without sunlight? A: Yes, it can also track strong artificial light sources like a torch.
• Q: What type of battery is used? A: Two 18650 rechargeable 3.7V Li-ion batteries are used for power.
• Q: Is this suitable for kids? A: Yes, it's designed for school and college students but under guidance.
• Q: How long does the battery last? A: A fully charged pair of batteries can last for several hours of continuous demonstration.

Challenges and Considerations

• The panel does not store energy; it only tracks light direction
• Single axis means it can only move left to right, not up and down
• Battery needs to be recharged after extended use
• Best used indoors or in shaded environments for demonstration control

Compatibility

• Compatible with any 5V Arduino-compatible sensors and actuators
• Can be upgraded to dual-axis tracking with additional programming and servo
• Works with standard 18650 batteries and USB Type-C charging ports

Future Enhancement Options

• Add solar energy storage using higher watt solar panels
• Include real-time data logging with SD card module
• Integrate an LCD display to show light intensity levels
• Upgrade to a dual-axis solar tracking system
• Connect to IoT platforms for remote monitoring

Benefits

• Introduces students to real-world renewable energy solutions
• Encourages hands-on learning and STEM innovation
• Low-cost, high-impact demonstration model
• Ready-to-use—saves time and effort for teachers and students
• Sold by বিজ্ঞান প্রজেক্ট (Bigyan Project), a trusted source of science projects in Bangladesh
