Sun Tracking Solar Panel Using Arduino

Sun Tracking Solar Panel Using Arduino
Solar energy is one of the most promising renewable energy sources, but fixed solar panels only capture sunlight efficiently for a few hours each day. To maximize energy output, solar panels need to follow the sun's movement across the sky throughout the day.

Our Solution: Project Center Kerala presents an Arduino-based sun tracking solar panel system that automatically adjusts the panel's position to face the sun directly. This intelligent tracking mechanism can increase energy efficiency by 30-40% compared to fixed solar panels.

How It Works: The system uses Light Dependent Resistors (LDRs) as sensors to detect the sun's position and servo motors to adjust the panel's orientation. The Arduino microcontroller processes sensor data and controls the movement, ensuring the panel always faces the brightest light source.

Key Components:

Arduino UNO microcontroller for processing and control
Solar panel for energy generation
Servo motors (SG90) for dual-axis movement
LDR sensors for light detection and positioning
Resistors and breadboard for circuit connections

Features:

Automatic dual-axis sun tracking (horizontal and vertical)
Real-time light intensity comparison
Smooth servo motor control for precise positioning
Energy-efficient operation with minimal power consumption
Weather-resistant design suitable for outdoor installation

Applications: This technology is perfect for residential solar installations, educational projects, research applications, and small-scale renewable energy systems. It's an excellent way to learn about solar energy, automation, and sustainable technology.

Benefits: Increased energy output, reduced payback time for solar investments, educational value for students, and contribution to sustainable energy solutions.
