Ramming Pile Solar Ground Mount - Slope Area

The Ramming Pile Solar Ground Mount - Slope Area utilizes hot-dip galvanized steel piles hydraulically driven, eliminating the need for concrete. Its dual-column structure with adjustable points allows for inclination angles from 0 to 60°, wind resistance up to 60 m/s, snow load resistance up to 1.4 kN/m², corrosion and weather resistance, and a design life exceeding 25 years. Simultaneously, the system preserves the original terrain, eliminating leveling costs, shortening the construction period by 30-50%, and reducing labor costs by approximately 20%. Its modular prefabrication makes it suitable for slopes and remote areas, making it an ideal choice for rapid grid connection and high-return power plants.

Product Components

Advantage

▪ Unfazed by complex terrain, maximizing land use:

Designed specifically for slopes and hills, it can be installed directly on existing terrain, eliminating the high costs and time associated with traditional methods that require extensive earthwork leveling. Its dual- or multi-column support structure can flexibly adapt to ground undulations in the north-south and east-west directions.

▪ Flexible adjustment ensures optimal power generation angle:

Equipped with flexible rotating joint components and adjustable-length supports, the system allows for a wide range of multi-directional adjustments at the top of the support, ensuring the photovoltaic panels are precisely oriented due south and achieve the optimal tilt angle, guaranteeing high-efficiency power generation even in complex terrain.

▪ Highly efficient and quick installation, shortening construction time:

Hydraulic piling machines are used to directly drive steel piles into the ground, completing a pile foundation in seconds. Many systems also employ a highly pre-assembled modular design in the factory, significantly reducing on-site assembly time, increasing installation speed by up to 50% compared to ground bolt solutions.

▪ Robust and durable, safe and reliable:

Core load-bearing components (such as steel piles and main beams) are hot-dip galvanized or zinc-aluminum-magnesium coated, possessing extremely strong corrosion resistance and aging resistance. Product warranties are generally 10 years. Wind resistance is generally above 60 m/s (sufficient to withstand a Category 17 hurricane), and snow load capacity is generally 1.4 kN/m² or higher.

▪ Environmentally friendly with minimal ecological impact:

The installation process eliminates the need for large-scale excavation and concrete pouring, greatly protecting the original topography and vegetation and minimizing disturbance to the local ecosystem.

▪ Economically efficient with reduced overall costs:

Although the initial investment in piling equipment and specialized supports may be slightly higher, reducing earthwork, shortening the construction period, saving labor, and maximizing land use results in a better return on investment throughout the entire life cycle.

Parameters

Applicable Scenarios

Medium to large-scale commercial and ground-mounted photovoltaic power plants: Especially suitable for hilly, slope-covered, and ravine-riding agricultural or unused land, these plants can adapt to the terrain through support structures, achieving agricultural-solar complementarity.

▶ Utility-grade photovoltaic power plants:

Among large-scale ground-mounted power plants, the piling method offers fast construction speed and strong terrain adaptability, making it the preferred choice for ensuring project schedules for large-scale projects.

▶ Ecological areas with high environmental protection requirements:

This foundation type, which causes minimal damage to the land, effectively mitigates environmental approval risks.

▶ Areas with complex geological conditions:

Various complex geological conditions can be adapted by changing the foundation type (such as helical piles or PHC piles).

Important Notes:

Despite its clear advantages, careful evaluation is necessary in certain scenarios:

 

▪ Relatively limited pull-out strength: In extremely soft foundations or high-wind-speed areas, its pull-out performance may be weaker than deeply buried concrete foundations.

 

▪ Difficulty in construction in hard rock formations: Insufficient geological surveys may hinder piling, often requiring pre-drilling assistance.

 

▪ Corrosion challenges: In saline-alkali lands and highly corrosive coastal environments, the galvanized coating of impact piles faces corrosion risks; helical piles are recommended as a priority.

 

▪ Gravelly soil layers may damage the galvanized coating: Gravel may scratch the anti-corrosion coating on the pile surface, affecting its long-term lifespan.

 

Installation

• 

  01 Screw Pile Driving

  Use a hydraulic pile driver to drive hot-dip galvanized steel piles into the sloping ground according to their positioning, ensuring a verticality deviation of ≤1°.

• 

  02 Installing Columns

  Install adjustable columns on top of the steel piles and initially secure them with bolts.

   

• 

  03 Installing Inclined Beams

  Erect the inclined beams on top of the columns and adjust them to the optimal tilt angle for power generation.
• 

  04 Installing Diagonal Bracing

  Install diagonal bracing between the columns and inclined beams to enhance the support structure's wind and bending resistance stability.

• 

  05 Installing Tie Rods

  Install tie rods crosswise between the column rows to improve the longitudinal stiffness and anti-slip capability of the entire support structure.

   

• 

  06 Installing Purlins

  Arrange and fix the purlins perpendicular to the inclined beams to form a flat mounting surface for the solar panels.

   

• 

  07 Installing Solar Panels:

  Lay the photovoltaic modules on the purlins, lock them in place with clamps, and allow for thermal expansion gaps.
