Where can I buy photovoltaic support cement piers

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.

What are the most common solar ground mounting solutions?

The five most common solar ground mounting solutions — C post, helical anchors, ground screws, concrete piers and ballast. It really depends on soil condition under your feet. C-post Roll formed C posts are a common component across the field of construction, they are also the most common ground-mount option for solar systems.

What equipment options are available for solar array installation?

What equipment options are available for their installation? 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.

What are the advantages and disadvantages of concrete piers?

Using concrete piers for Earth Anchors in PV Ground Mounted Arrays has several advantages. Minimal equipment is required for installation, and they can be relatively shallow compared to driven steel piles. However, there are also disadvantages. Concrete is used, which takes days to cure, and the process is labor intensive. Additionally, the steel post must be embedded the full depth of the pier, or rebar cages must be used.

What is a concrete pier?

A concrete pier is a drilled and cast-in-place foundation type for small to medium sized projects. The advantages of concrete piers are that minimal equipment is required for installation, and they can be relatively shallow compared to driven steel piles.

Are helical piles a good choice for solar array anchoring?

Depending on ground conditions, helical piles can often be shorter in length and therefore cost less in installation time and energy consumption than comparable driven piles or drilled shafts. Some manufactures of helical piles for solar array anchoring assert installation rates as high as 500 piles per day.
