Slew drives for solar trackers
Worm gear slew drives rotate single-axis tracker rows to follow the sun and lock them against wind.
- What was needed
- Worm & Worm Wheel
- Requirements
- Slow, precise rotation
- Holds position in strong wind
- Long outdoor life
- Industry
- Solar & Renewable Energy
- Result
- Tracker rows that follow the sun and lock against wind loads.
Problem
Single-axis trackers turn long rows of panels slowly through the day and must hold their position in strong wind, outdoors, for decades.
Solution
Tracker slew drives use a worm gear: a large reduction for fine, slow movement, and self-locking so wind loads cannot back-drive the row.
Benefits
Why it works
Precise, slow rotation
Fine angular control for tracking.
Holds against wind
Self-locking worm geometry.
