If you are ordering the IronRidge pre-configured ground mounted solar panel racking solution but supplying your own solar panels [Not Purchased from BPS], you will need to note in the checkout process at “SHIPPING PREFERENCES - Special instructions about delivery:” the solar panel manufacture and model number of the panel you intend to use so we can size the end clamp stopper sleve accordingly.
Per NEC 2017 code 690.31(A) and 110.27(A) PV wires under the ground array need to be guarded against accidental contact. Check with your local AHJ (Authority Having Jurisdiction) for your local requirements. If required, in our experience chicken wire over the PV wire on the back side of the array runs the cheapest and easiest solution. Other options may include a low fence around the perimeter of the array.
A question we often get asked is my soil is very rocky. Do you have any foundation designs aside from concrete pier 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. A alternative solution for these soil types would be having us engineer a spread footer. Consult an engineer for structural review if using a foundation design other than those described in the IronRidge Certification Letters. (NOTE: Engineering spread footer requires the addition of the optional Blue Pacific Solar® Permit Document Service with the Optional Structural Engineering Review & Wet Stamp.)
Blue Pacific Solar uses IronRidge on most of our roof or ground mount rack applications. Customers appreciate tilt angle and the professional appearance, ease of assembly and abundant support documents and installation videos found exclusively with IronRidge products. IronRidge Ground Mount System is a reliable, comprehensive, and feature rich solar panel mounting system. Anchored by IronRidge standard rails, the IronRidge ground mount platform includes all of the components necessary for supporting virtually any commercial or residential ground mount installation, regardless of application. In addition to manufacturing solar ground mounts, IronRidge provides a complete engineering support system for solar mounting and racking including installation guides, span charts, and certification letters to help you every step of the way. All IronRidge products are fully-certified, code-compliant, listed to UL 2703 and backed by a 25-year warranty
Blue Pacific Solar® permit document service is offered as a value added service for our customers only who purchase our grid-tied or off-grid packages of 18 panels [Minimum] or more. The building permit document permitting service service is available for most states to help you get through your local jurisdiction building permit process. Our team of professional designers can provide the documents, blueprints and expertise needed to work with any building department nationwide.
When should I use 3" versus 2" Schedule 40 steel pipe for my sub-structural material? 2" Schedule 40 steel pipe is generally used for smaller arrays, such as residential applications, because it’s lightweight and easy to handle. 3" Schedule 40 steel pipe is most useful for larger arrays, where the longer E-W span helps reduce the number of concrete foundations. But, 3" Schedule 40 steel pipe is also heavier and sometimes requires heavy machinery for installation. Before purchasing your pipes, confirm the specifications with the Parts Catalog.

Consult an engineer for structural review if using a foundation design other than those described in the IronRidge Certification Letters.
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 the IronRidge Certification Letter for dimension details. The certification letters can be found in the Documents & Resources section under the Ground-based tab on the IronRidge website.
What design constraints should I be aware of when building an array on an East to West slope? The maximum "above ground length" for the southern vertical piers is 2'6". To prevent exceeding this length on either side of the array, break the array into segments. This "stepped" array 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 alternative approaches.
How do I suspend my vertical piers while I pour concrete? Many installers create a temporary set of "forms" to suspend the East to West cross pipes, with the vertical pipes already attached to them. This approach allows you to assemble and level your sub-structure at the appropriate height, then pour all of the concrete at once. Always refer to the Ground Mount Installation Manual prior to assembly.
How do I calculate row spacing to avoid shading? This question depends on what is considered an acceptable amount of annual "shade loss" (system output lost to inter-row shading). If your goal is zero shade loss, visit the first the NOAA Solar Calculator (http://www.esrl.noaa.gov/gmd/grad/solcalc/) to find the minimum solar altitude angle (El) on December 21st at 10 A.M., 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.
