Product Description
This system combines the lightweight, high-strength and corrosion-resistant characteristics of the aluminum alloy support with the stable and reliable load-bearing capacity of the concrete foundation, and has become one of the most widely used support schemes in the current construction of ground-based photovoltaic power stations.
This product can be widely applied in various open terrains such as grasslands, sandy areas, deserts, and even existing concrete surfaces. It is suitable for large-scale centralized photovoltaic power stations, industrial and commercial distributed photovoltaic projects, as well as agricultural photovoltaic integration and other scenarios. Depending on the different foundation forms, it can be used in conjunction with foundation schemes such as concrete strip foundations, concrete independent foundations, or spiral pile foundations.

Advantage
Aluminum alloy photovoltaic (PV) brackets offer significant advantages over traditional steel brackets in several aspects:
Parameters
| Installation | Ground |
| Wind Load | up to 60m/s |
| Snow Load | 1.4kn/m² |
| Standards | GB50009-2012, EN1990:2002, ASE7-05, AS/NZS1170, JIS C8955:2017, GB50429-2007 |
| Material | Anodized Aluminum AL 6005-T5, Stainless Steel SUS304 |
| Warranty | 10 Years Warranty |
Structural Types
Applicable Scenarios
• Large-scale centralized ground-mounted power stations: Large scale (MW and above), open terrain.
Lightweight and efficient aluminum alloy brackets, combined with stable and reliable concrete foundations, are the mainstream choice.
• Industrial and commercial distributed photovoltaics: Small to medium-sized projects such as factory open spaces and parking lots.
Concrete ballast foundations are flexible and adaptable to existing ground conditions, with short installation cycles.
• Agricultural photovoltaic complementary projects: Crops are planted under photovoltaic modules.
The height of the concrete foundation is adjustable (500-2000mm), ensuring space for agricultural use.
• Fishery photovoltaic complementary projects: Photovoltaic modules are erected above fishponds.
Concrete pile foundations are corrosion-resistant and stable, suitable for areas with fluctuating water levels.
• Strong wind/snowy areas: High wind loads and thick snow accumulation.
The system has been verified through wind and snow resistance limit state calculations and is suitable for wind speeds ≤60m/s and heavy snow conditions.
Applicable Soil Types
Geological Limitations to Consider
The following geological conditions may render concrete spread foundations unsuitable or extremely difficult to install due to insufficient bearing capacity or soil instability, requiring prior assessment or alternative foundation types:
▶ Soft Soil
Including silt, silty clay, peat, and fill. High natural water content and extremely low bearing capacity (typically fak < 80 kPa), prone to compression deformation and overall instability.
▶ Problemmatic Soils
Collapsible loess, expansive soil, frozen soil, and saline soil. Significant settlement, volume expansion, and frost heave occur upon contact with water, severely compressing foundation stability.
▶ Underconsolidated Fill
Recently filled, shortly stockpiled, and complex-composition plain fill and miscellaneous fill. Not yet fully consolidated under its own weight, resulting in large and uneven settlement.
▶ High Corrosion Soil
While the direct impact of soil chemistry on the concrete itself may be limited, it can affect the long-term durability of the foundation through groundwater infiltration, thus requiring specific assessment.
▶ Special Terrain
In areas with steep slopes, inclines, or high groundwater levels, the stability of extended foundations is difficult to guarantee.

Carbon steel ground photovoltaic support - Helical ground pile foundation: The core material is Q235B/Q355B carbon steel. It consists of helical ground piles (including pile heads, steel pipe piles with spiral blades, and top connectors) buried underground and the ground support structure above ground. It is installed by mechanical screwing into the soil to serve as the load-bearing foundation for the photovoltaic array. All components are treated with hot-dip galvanizing (with an average galvanizing layer thickness of ≥ 80 μm), achieving full metal connection. It features ready-to-use, no excavation, and recyclability, and is a modern solution to replace traditional concrete foundations.
