If you really want to know how big a footer is needed you need to know how much weight you need to support and the strength of the soil under your house. Without real numbers any footing size is just a guess. Generally a 2' square by 12" deep is considered the minimum size for a pier/spot footer.
Concrete block shall have enough surface area to resist the lateral load through friction or be embedded into the ground to resist. Due to the amount of weight and surface area required at each leg and the space available, it is typical to link the front and back legs together with a single ballast block.
Various options exist for anchoring ground mounted solar arrays. These include drilled shaft piles (also called micropiles or caissons), driven piles and helical piers or ground screws. Racking manufacturers generally specify the depth, diameter and spacing of the anchors based on the site conditions including soil type and environmental .
Weight Calculation: The ballast weight required depends on factors like solar array size, wind loads, and specific site conditions. Engineering calculations ensure that the ballast is sufficient to resist environmental forces.

6 FAQs about [Calculation of weight of cement pier for photovoltaic support]
How do you install solar panels in a concrete pier?
Concrete Piers: Concrete footings are poured into the ground to support the solar array. This method is commonly used for smaller-scale installations or regions with specific soil conditions. Before installing the solar panels, thorough ground preparation is essential to ensure a level and stable foundation.
What are the different types of solar piers?
Helical Piles: Similar to driven piles, helical piles have a screw-like design, providing anchoring strength for the solar array. They are ideal for sites with weak or sandy soil. Concrete Piers: Concrete footings are poured into the ground to support the solar array.
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 big is a concrete pier?
Reference spMats Engineering Software Program Manual v8.50, StucturePoint LLC., 2016 Design Data Concrete Pier Size = 3.0 ft Diameter Height = 4.0 ft Concrete Footing Size = 10.0 ft x 10.0 ft f c’ = 4,000 psi f y = 60,000 psi Thickness = 24 in. Clear Cover = 3 in.
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 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.
