Selection of independent foundation for photovoltaic support

How is a ground mounted PV solar panel Foundation designed?

This case study focuses on the design of a ground mounted PV solar panel foundation using the engineering software program spMats. The selected solar panel is known as Top-of-Pole Mount (TPM), where it is deigned to install quickly and provide a secure mounting structure for PV modules on a single pole.

How do I choose a foundation for a solar project?

Understanding a potential solar project’s ground conditions can influence many design considerations, most importantly what foundation to choose. The most economical foundation design can depend on geographical location, soil type, local building code requirements, groundwater levels, corrosion potential and topography.

What types of foundations are used for solar panels?

Different foundations are used based on the site’s soil conditions, local regulations, and project scale. Concrete Ballast: Concrete blocks or pads are strategically placed on the ground to provide weight and stability to the solar array. This non-penetrating foundation is often used when soil penetration is restricted or prohibited.

Why is foundation selection important?

Foundation selection is critical for a cost effective installation of PV solar panel support structures. Lack of proper investigation of subsurface conditions can lead to selection of the wrong foundation type and can result in costly change orders and delays to the job completion date.

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 are the different types of ground mount solar foundations?

Categories of typical ground mount solar foundations. Drilled and cast-in-place drilled shafts or piers are routinely used to support a number of structures to resist both axial compression and lateral loads.
