Tech Explained | Tracking vs Fixed Mounts: Which is Right for Your Solar Plant

Publish Time:2025-04-23 Sources:

In PV plant construction, the choice of mounting systems directly impacts energy yield, ROI, and long-term O&M costs. As the "skeleton" of a solar project, mounts must not only support modules but also adapt to environmental conditions for maximum returns.


So, which delivers better value—tracking mounts for efficiency or fixed mounts for economy


Energy Yield: Trackers "Chase the Sun," Fixed Mounts Stay Steady
1.Fixed Mounts: Simplicity & Reliability
Fixed-tilt design, easy installation.
Typical efficiency: 75%-85% annual yield at optimal tilt.
Best for: Low/mid-latitude regions with stable irradiance.
2.Tracking Mounts: AI-Powered Precision
GraceSolar’sSmart Tracking Systemuses AI to follow the sun’s path, boosting output.
15-25% higher yield vs fixed mounts.
Smart features: Weather adaptation, shadow avoidance, and energy-saving modes.

Verdict: Trackers win for max output (e.g., high electricity price markets); fixed mounts suit budget-sensitive projects. 



Cost Comparison: Upfront vs Lifetime Value
1.Fixed Mounts:
Lower CAPEX: Simple structure, faster ROI.
Minimal O&M: No moving parts—the "workhorse" of solar.

2.Tracking Mounts:
Higher initial cost(30-50% more) butlower LCOEin high-irradiance areas.
Payback: 1-3 years faster in ideal conditions.

Key Insight: Trackers shine where energy prices or scale justify the investment.



Application Scenarios
1.Fixed Mounts Excel In:
Low-latitude zones (e.g., Southeast Asia)

Harsh environments (sand, salt corrosion)


2.Tracking Mounts Dominate:
Utility-scale plants (deserts, open fields)
High-latitude regions (e.g., Europe/North America)

Bifacial modules (10-20% rear-side gain)


Global Case Studies: 
Japan: Enhanced low-light performance.
Middle East: Sand-resistant design + automated cleaning.

Agrivoltaics: Elevated structures for crop compatibility.



O&M: Which is Easier
1.Fixed Mounts:

Near-zero maintenance (bolt checks annually).


2.Tracking Mounts:

Past challenges: Motor failures, calibration drift.


GraceSolar’ s solution:
AI predictive maintenance + storm-proof engineering (wind tunnel tested).

Remote monitoring via IoT.
