Utility-grade solar developers know “perfect” sites come at a premium. That’s why they’re constructing more PV on rocky, hilly terrain with down-to-earth pricing. These cheap-but-challenging sites can seem like a safe route to higher margins, but construction issues can quickly turn good projects into quagmires.
Choosing the right ground-mount foundation is key. Figuring out how to weigh the costs and benefits to pencil out strong projects will deliver the best returns and the lowest risks. Foundation options like ground screws and piles present unique considerations with varying ramifications on schedules and budgets.
Join us as we explore the risks and rewards of driven-pile and ground-screw foundations on soft sites versus tough terrain. With a combined 20+ years of experience in large-scale solar design, engineering and construction, Terrasmart experts will share an objective perspective to determine the best path to project success.
Terrasmart is the only provider of both ground-screw and driven-pile foundations. Our experts will guide you through a product-neutral evaluation. We’ll dive into:
- A cost/benefit analysis between ground screws and pile foundations
- The advantages and risks in a soft environment compared to a high-refusal site
- The cost and schedule impact of remediating piles driven to refusal using different methods
- A break-even analysis comparing both foundations on time and budget
Choosing the right foundation is key to making sure cheaper dirt doesn’t land you in the red. Look forward to you joining us!
