Photovoltaic cast-in-place pile support installation requirements

Are driven piles suitable for ground mount solar panels?

The design for uplift behavior of shallow footings has been discussed extensively by Kulhawy (1985) and Trautmann & Kulhawy (1988). Driven piles are an attractive foundation alternative for ground mount solar panel systems since the materials are readily available and Contractors are familiar with the technology.

What considerations should be taken during installation of solar panels?

During installation, several key considerations must be taken into account to ensure the success of the project. Alignment is crucial; maintaining proper alignment of the piles is essential to prevent issues during the installation of solar panels.

How do I choose a pile for a solar farm?

The load-bearing capacity needed for the solar farm is another critical factor in selecting the type of pile. Projects requiring high load capacities—such as those with large, heavy solar panels or in regions with significant wind forces—may necessitate the use of concrete or composite piles.

What is the best foundation support for ground mounted PV arrays?

Drilled concrete piers and driven steel piles have been, and remain the most typical foundation supports for ground mounted PV arrays. However, there has been a push for "out-of-the-box" foundation design options including shallow grade beams, ballast blocks, helical anchors, and ground screws.

How are driven piles installed?

Driven piles are installed very quickly by pile drivers, of which there are several commonly used types such as the GAYK and Vermeer. Some of these machines are highly sophisticated, with GPS guidance and automated installation technology allowing installation of piles for very low cost, considerably below that of other foundations.

What is a drive pile for a ground mount solar system?

Driven piles to support ground mount solar systems are typically lighter duty that those used for other structural applications with pipes typically in diameters ranging from 4 to 8 in. in diameter and H-piles typically made from W sections with flanges between 6 and 10 in.
