These slender, high-strength piles boast diameters typically ranging from 100mm to 300mm, making them well-suited for applications where space is limited or environmental
This novel proposes a hybrid power generation system to solve telecommunication industry issues, such as increased operational expenditures (OPEX) and carbon em
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
To clearly identify a break-even datapoint that pinpoints where driven piles are the best option or where ground screws would deliver a better result, we brought together the
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

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.
Case study #1 (steel piles in windy environments): A solar farm in a coastal area with high wind loads utilized steel piles with additional corrosion protection. The flexibility of steel allowed the piles to withstand both the high wind forces and the corrosive coastal environment.
The number of pile foundations can vary from a few thousand for a small solar farm to in excess of 100,000 for a large solar farm. Two issues are addressed in this paper. First, the relatively short lengths of the piles means that soil expansion and contraction are important factors.
This paper addresses geotechnical and structural aspects of pile design for solar farm foundations. The work incorporates aspects of numerical modelling, unsaturated soil mechanics and stochastic analysis which were all championed by Scott Sloan. The work was made possible by the connections made with co-authors and others through the CGSE.
