How deep underground is the best for piling photovoltaic panels

How deep is a drilled shaft pile for a solar array?

Drilled shaft piles for solar array footings can vary anywhere from 6 to 24 inches in diameter and 5 to 30 feet deep, depending on site conditions and other variables. The drilled shaft or borehole is filled with high-strength cement grout or concrete. At times, steel casing or re-bar is used for reinforcement.

Do solar panels need ground screws?

Solar panels naturally have a large surface area to capture the sun’s rays, but this acts like a sail in the wind. Ground screws protect your solar array by securely anchoring it underground, delivering the best foundation solution, especially in wind-exposed areas.

What is a solar pile & foundation?

At Exactus Energy, we specialize in providing thorough solar pile and foundation designs to set you up for success through installation and beyond. Solar pile structures are foundational components supporting solar panel arrays, often composed of durable materials like steel or aluminum.

There are several benefits to choosing ground screws for your solar foundations. Download our brochure Find your local team

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.

Why should you choose galvanized steel screw piles for solar panels?

Because they represent a major investment, solar panels must be able to withstand the harshest weather conditions and have a long lifespan. With their durable and solid design, galvanized steel screw piles offer the most cost-effective solution for anchoring solar panels for the long-term.
