| Installation Site | Fill, clay/cohesive, silt, sandy and sandy-gravel soils after geotechnical review |
|---|---|
| Material | Typically Q235B-grade carbon steel or equivalent, hot-dip galvanized |
| Foundation/Fixing | Helical shaft with flange connection; dimensions and connection drawing confirmed per structure |
| Catalog examples (factory drawings) | 76 × 1600 mm examples: SN-GS-F76x1600, SN-AS-F76x1600, SN-AS-N76x1600, SN-GS-U76x1600, SN-DS-F76x1600, SN-FS-F76x1600, SN-WS-F76x1600. Other sizes confirmed per project in the written quotation. |
| Shaft Diameters | Typical diameters include about 76, 89, 102 and 114 mm. Final specs confirmed per project in written quotation. |
| Wall Thickness | Typically about 3–3.5 mm. Final specs confirmed per project in written quotation. |
| Pile Length | Typically about 1000–3000 mm. Final specs confirmed per project in written quotation. |
| Flange Diameter | Typically about 200–220 mm. Final specs confirmed per project in written quotation. |

Product overview
SolarNova is a supplier/exporter of helical ground screw piles for PV foundations. The factory catalog shows 76 × 1600 mm examples across standard helix, dual-helix, multi-helix and continuous-spiral forms, with flange, U-bracket or no-flange connections (SN-GS, SN-AS, SN-DS, SN-FS and SN-WS types). Listed dimensions are indicative; custom sizes need a project review rather than selection from a universal capacity table.
Fill, cohesive clay, silt, sandy and sandy-gravel soils may be considered after site investigation. Hard rock and dense gravel generally need special measures, and soft rock may require pre-excavation. We recommend on-site pull-out tests to verify the foundation design before releasing a project order.
Applications
- Fill, clay/cohesive, silt, sandy and sandy-gravel soils after geotechnical review
- EPC and installer procurement

View specificationsFrequently asked questions
Can pile capacity be selected from shaft size alone?
No. Soil conditions, helix geometry, installation depth and structural loads all matter. Require site investigation and use pull-out tests to verify the proposed foundation.
What materials are specified?
Typically Q235B-grade carbon steel or equivalent, hot-dip galvanized
What information is needed for a proposal?
Send the module drawings, site survey, local design loads and corrosion conditions. Listed figures are indicative; final specs confirmed per project in written quotation.
How are quantity, lead time and packing agreed?
Project quantity; sample availability and MOQ confirmed on inquiry. Typical lead time: 15–20 days after order and drawing confirmation; samples and standard parts faster. Export cartons or protected pallets; loading plan confirmed with quotation.
What warranty applies?
10-year product warranty, 25-year design service life.
What are the payment terms?
Contact us; commercial terms are confirmed in the written quotation.
