Definition
Fixed-tilt mounting holds PV modules at a constant tilt angle and azimuth, typically aligned for maximum annual energy at the site's latitude. Simpler, more reliable, and ~15–20% lower yield than horizontal single-axis trackers.
Key Takeaways
- Fixed-tilt = constant module angle and azimuth.
- Simpler and more reliable than trackers.
- ~15–20% lower yield than horizontal single-axis tracker.
- Optimal tilt ≈ site latitude.
- Dominant for commercial rooftop and small utility-scale.
Frequently Asked Questions
2 commonly searched questions about Fixed Tilt.
What is fixed-tilt?
Solar mounting where modules stay at a constant tilt and azimuth angle. Simpler than trackers; no moving parts.
Fixed-tilt vs. tracker economics?
Tracker: +15–25% yield, +30% CapEx, more maintenance. Fixed: simpler, longer-lived, lower yield. Crossover depends on site irradiance and tariff.
