What Is A Solar Tracker? The Ultimate Guide to Sun-Following Systems
Discover how advanced solar tracking systems boost energy output by 45%, reduce LCOE costs, and conquer challenging terrains
The Science Behind Solar Tracking
Solar trackers are intelligent mounting systems that dynamically adjust photovoltaic panels to follow the sun's daily path across the sky. Unlike fixed installations that maintain stationary angles, these electromechanical systems optimize sun exposure through:
- Real-time sun positioning using GPS coordinates and azimuth calculations
- Hybrid sensor technology combining tilt sensors and cloud detection
- Weather-responsive algorithms automatically activating storm protection modes
By maintaining near-perpendicular alignment with incoming sunlight throughout the day, modern trackers increase energy yield by 25-45% compared to fixed systems. Explore tracking system technologies →
