Ground Mount


IronRidge Ground Mount combines the strength of XR1000 rails with locally-sourced steel pipes to create a cost-effective structure capable of handling any site of terrain challenge.

Installation is simple with only a few structural components and no drilling, welding, or heavy machinery required. The System works with a variety of foundation options, including concrete piers and driven piles, and can support up to 5 modules per column.

The strongest rail in the industry makes it simple and secure to assemble columns of three to five modules.

Schedule 40 Pipe

Locally-sourced 2" or 3" schedule 40 pipe allows you to save on freight, while still spanning as high as 18' between vertical piers.

  • When should I use 3” versus 2” Schedule 40 steel pipe for my sub-structural material?

    2” Schedule 40 steel pipe is ideal for residential applications as it requires less foundation and consequently alleviates the need for heavy equipment during installation. 3” Schedule 40 steel pipe is suitable for commercial applications with its ability to span up to 17’. The large span capability greatly reduces the amount of overall piers needed. We suggest you confirm the dimensions of any pipe you purchase with the Ground Mount Engineering Design Guide.

  • Are the Grounding Mid Clamps an acceptable form of grounding with an IronRidge Ground Mount system?

    While the Grounding Mid Clamps meet all the structural requirements of the Ground Mount system and complete all the necessary bonding paths, the use of Grounding Mid Clamps with the Ground Mount system have not been formally tested to UL 2703. Therefore, some AHJs may not accept the use of Grounding Mid Clamps with the Ground Mount system. We suggest you check with your local jurisdiction before ordering materials.

  • Is UL 2703 a new standard?

    Locally-sourced 2" or 3" schedule 40 pipe allows you to save on freight, while still spanning as high as 18' between vertical piers.

  • How should I splice my Schedule 40 steel cross pipe?

    The most common method for splicing Schedule 40 steel pipe is with the use of a threaded coupler. This requires that the pipe be ordered from the manufacturer threaded or that a threading tool be available onsite. Welding the pipes directly to one another or using welded couplers are also acceptable options. Keep in mind that the splice should not fall within the middle third or on the end span (cantilever) of the cross pipe.

  • My soil is very rocky. Do you have any foundation designs aside from concrete footings?

    IronRidge provides standard foundation sizes for various soil classes. However, some soils may be extremely difficult to dig into, such as granite or rocky soils. Solutions for these soil types include epoxying re-bar into the granite and pouring the foundations above the ground, connecting the piers with low depth grade beams, or casting the piers into above ground ballast blocks. Consult an engineer for further structural review if using a foundation design other than the recommended concrete footings.

  • What determines my North to South pier spacing?

    North to South pier dimensions are static measurements in our Ground Mount design that are either 7.5’ or 9’, depending on the number of modules per column. Refer to the assembly drawing found at the bottom of your project’s corresponding certification letter for dimension details. Certification letters can be found in the System Support section under the Ground Mount tab on the IronRidge website.

  • What t design constraints should I be aware of when building an array on an East to West slope?

    To prevent exceeding the recommended above ground length of the south piers on either end, break the array into segments. This “step” array method will prevent the East or West side of the array from being too high. If this is not a viable option, consult an engineer for further structural review.

  • How do I suspend my vertical piers while I pour concrete?

    Creating a temporary structure to brace East to West cross pipes will allow for suspension of the piers while concrete is poured and sets. You will need to assemble your vertical piers and cross-bracing before propping them up at the appropriate height. Always refer to the Ground Mount Installation Manual prior to assembly.

  • How do I calculate row spacing to avoid shading?

    First, find the minimum solar altitude angle (El) on December 21st at 10 A.M. for the project area. This value can be found with the NOAA Solar Calculator ( ) by inputting the coordinates of the project area. Use the following formula to find distance (D) between arrays to avoid shading: D’=h/tan(El). Height (h), is the difference between the rear edge of the first array and leading edge of the second array.
