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.

How thick is a photovoltaic concrete shell?

At an average thickness of approximately two-inches, this work provides endless insights for the future of photovoltaic concrete, and demonstrates that it is possible to build a thin concrete shell using flexible formwork and photovoltaic elements. Research Photovoltaics Manufacturers

What is a photovoltaic concrete structure?

Researchers of the Block Research Group at ETH Zurich have developed an ultra-thin, self-supporting, photovoltaic concrete structure with multiple layers of functionality. Beyond just power generation, this incredibly sinuous structure offers thermal regulation, insulation and waterproofing properties.

Can a concrete façade double the power harvesting capacity of traditional roof-based solar?

With two different yet complementary sets of knowledge, LafargeHolcim and Heliatek joined forces to create an architectural concrete panel façade system with the potential to double the power harvesting capacity of traditional roof-based solar technologies.

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.
