Top 4 Common Solar Mounting Installation Mistakes
April 11, 2025
1.Unlevel Foundation
- Foundation tilt >3° causes rail stress concentration.
- Solution: Use a laser level to calibrate.
2.Over-Tightened Bolts
- Can deform aluminum rails.
- Torque specs: ≤25N·m (M8 bolts: 15-20N·m recommended).
3.Improper Grounding
- Lightning strike risk increases by 300%.
- Requirement: All strings must be grounded with clips.
4.Inadequate Corrosion Protection
- Coastal projects require ≥80μm zinc-coated components.
