Definition
A dual-axis solar tracker rotates modules on two axes — east-west daily and north-south seasonally — to maintain perpendicular orientation to the sun throughout the year. Yields +25–30% over fixed tilt but costs roughly 2× a single-axis tracker.
Key Takeaways
- Dual-axis tracker = rotation on both east-west and seasonal axes.
- +25–30% yield over fixed tilt.
- ~2× cost of single-axis tracker.
- Niche use; single-axis dominates utility scale.
- Best for high-latitude sites and research applications.
Frequently Asked Questions
2 commonly searched questions about Dual-Axis Tracker.
Dual-axis vs. single-axis tracker?
Single-axis: +15–22% over fixed. Dual-axis: +25–30%. Dual-axis costs 2× single-axis. Single-axis dominates utility-scale; dual-axis niche.
When is dual-axis used?
Specialty applications: high-latitude sites where seasonal sun-path variation is large, research installations, premium residential. Rarely economic for utility-scale.
