Driven Pile Foundations

Foundation Solution

Driven steel pile foundations engineered for ground-mounted solar PV systems, providing a robust and efficient solution for suitable ground conditions

Overview

Driven piles provide a direct and efficient foundation solution for ground-mounted solar PV systems.

At HTR Solar, our driven pile foundations are installed directly into the ground and engineered to suit the project-specific mounting system, structural requirements and site conditions. Pile positions, spacing, installation height and embedment requirements are defined through the project-specific design documentation. 

For our twin-post mounting systems, front and rear pile rows form the foundation for the above-ground structure, providing an integrated foundation solution for the complete solar mounting system.

Why Choose Our Driven Pile Foundations?

  • Direct-to-Ground Installation

    Our driven pile foundations are installed directly into the ground, creating a practical foundation for ground-mounted solar PV systems.

  • Project-Specific Engineering

    Pile layout and installation requirements are defined through project-specific drawings and design documentation, allowing the foundation arrangement to respond to the requirements of each project.

  • Integrated with HTR Solar Mounting Systems

    Our driven pile foundations are designed as part of the complete HTR Solar mounting system, including twin-post configurations with coordinated front and rear pile rows.

  • Defined Installation Tolerances

    Foundation tolerances for height, alignment, twist, verticality and pitch support accurate installation and efficient assembly of the above-ground structure.

  • Designed to Follow Site Topography

    Our mounting systems are designed to follow the natural ground profile, helping accommodate variations across the site.

Ground Conditions & Driven Pile Design

Every solar site presents different ground conditions, so our driven pile foundations are developed around the requirements of each project. Pile layout, installation height and embedment requirements are defined through the project-specific design documentation. Where required, site testing and verification can be used to confirm pile performance and support the final foundation design. The manual also provides a procedure where piles cannot achieve the specified design depth, including in-situ load testing to the required design load.

Driven Pile Installation & Site Support

Accurate pile installation is essential to the performance and efficient assembly of the complete solar mounting structure. HTR Solar defines project-specific installation requirements and foundation tolerances to support accurate setting out and installation. Our mounting systems are also designed to follow the natural ground profile, helping accommodate variations in site topography.
