RBI engineers design a solar mounting system specifically to your project needs. We understand that there is no single solar racking solution that fits all sites because each and every site is different – geographically, topographically, and with respect to structural loading requirements. Based on the solar module, mounting type, project size, and soil conditions, RBI provides a custom-engineered racking design specific to the site conditions at your solar farm.

Foundation Options

We understand that foundations are the most important element of a solar mounting structure; that is why we provide a complete foundation design along with signed and sealed structural drawings. Our engineers design foundations to have an adequate load capacity with limited settlement. We consider all applicable design aspects including – but not limited to – the characteristics of the soil, weight of the structure, live loads, transient loads, and settlement when designing the foundation for the most economic and robust solar racking structure in the industry.

Foundation type may vary due to soil conditions and penetration restrictions. RBI Solar engineers are experienced in working with different foundation types including

  • Driven Post
  • Concrete Piers
  • Spread Footings
  • Helical/Screw Type Anchors
  • Floating Ballast

*All the foundation designs are done per the latest applicable codes, such as IBC and ASCE 7– Minimum Design Loads for Buildings and Other Structures.

Pull Test/Geotech Reports

Depending upon the soil conditions and scale of projects, RBI offers on-site pull out tests to determine the soil characteristics of a prospect solar farm site. Our team of experts travels to your jobsite with high tech post driving equipment to determine the required factors for foundation design.
