Helical Pile

Xiamen Honor Energy makes ground screws that act as the foundation for solar ground-mount systems. The process is straightforward: drive it into the soil with specialized equipment, then bolt the mounting rail directly to the top flange. It replaces traditional concrete footings, skipping excavation, pouring, and curing—the mounting structure can go up the same day. For soil types, it performs best in sandy loam, silty clay, and backfill—soft to medium-dense ground. Coastal salt spray and humid conditions are fine too. Hard clay and gravelly sites work with pre-drilling; pure rock or permafrost is not recommended .

Advantages

1. Fast: An experienced crew can install several hundred per day; rails go up same-day, cutting the project timeline vs. concrete.

2. Soil-flexible: Works in sand, clay, and gravel—swap helix or adjust length to match.

3. Corrosion-resistant: Thick hot-dip galvanizing holds up in coastal salt spray, rated for a 25+ year lifespan.

4. Eco-friendly: No construction waste; removable and recyclable at the end of the project, low land restoration cost.

5. Strong load capacity: Helix compacts surrounding soil, delivering solid pull-out and compression resistance.

FAQ

Q: How long does it take to install one? 

A: With a dedicated driver, about 2-3 minutes per screw under normal conditions. A crew can do several hundred a day—way faster than waiting for concrete to cure.

Q: My site is hard clay—will it work? 

A: Yes, but pre-drill first. Hard clay creates too much resistance; driving directly risks snapping the helix or stalling. Drill a pilot hole slightly smaller than the shaft, then screw in. Rocky ground is not recommended—it chews up equipment.

Q: What's the difference between hot-dip and regular galvanizing? 

A: Hot-dip is much thicker and bonds better—typically 65 μm+. It holds up 20-30 years in coastal salt spray or wet soil. Regular electroplating is thin and flakes off outdoors within a few years. Solar plants are designed for 25+ years; the foundation isn't where you cut corners
