All deliverables are provided as a complete, AHJ-ready PDF permit package. For commercial solar plan sets and utility-scale arrays, plan sets are formatted to match local submittal conventions. See our guide to solar energy diagrams for a full breakdown of what each drawing sheet must contain.

Ground Mount Engineering Requirements

Ground-mounted solar systems require more engineering documentation than rooftop installations because the structure is independent of an existing building. AHJs commonly require a separate structural engineer of record for the racking, foundation, and array frame, in addition to the standard electrical engineering documentation.

Key engineering requirements for ground mount permit submittals typically include:

• Wind and snow load analysis: Per ASCE 7-22 (or applicable edition) for the project location, applied to the array and support structure. See our ASCE 7-22 solar wind load guide for how these calculations apply to ground-mounted arrays.
• Soil bearing capacity: AHJs often require a soils report or geotechnical letter for driven post or helical pier foundations. We can flag this requirement early in the review process.
• Structural member sizing: Column, purlin, and rafter sizing backed by calculations showing allowable stress or LRFD compliance.
• Foundation design: Concrete footing dimensions, embedment depth, and reinforcement details for poured foundations; helix diameter, pitch, and torque spec for ground screws.
• Setback compliance: Distance from property lines, buildings, easements, and overhead utilities per local zoning and NEC 690.
• Electrical engineering: AC and DC circuit design per NEC 690 and 705, including rapid shutdown compliance under NEC 690.12. See our NEC 2023 Article 690 updates guide for a full breakdown of current code requirements.

Our engineering team reviews AHJ-specific requirements for each jurisdiction before finalizing drawings. If your local building department has a ground mount checklist or custom submittal form, share it with us, and we will incorporate those requirements into the package.

Foundation and Structural Calculations for Ground Mount Arrays

Foundation design is the most variable element of a ground mount permit package. The correct foundation type depends on soil conditions, frost depth, system size, and local code requirements. Solar Permit Solutions provides stamped structural calculations for all common ground mount foundation systems.

Foundation types we engineer and document:

• Driven steel posts (pipe or wide flange): Standard for residential and light commercial arrays. Embedment depth is calculated against frost depth and lateral load requirements for the site’s wind zone.
• Concrete piers (round or square): Used where soil bearing capacity is marginal or where the AHJ requires a traditional footing. We provide reinforcing schedules and concrete specifications.
• Ground screw / helical pier systems: Increasingly specified for agricultural and rural installs. Calculations include helix bearing area, torque correlation factor, and minimum tip depth.
• Ballasted foundations: For low-profile arrays on stable, flat terrain where excavation is not feasible. Ballast weight calculations account for local wind uplift and seismic factors.

Structural calculations are prepared and stamped by a licensed PE in the state where the project is located. If a geotechnical report is required, we will identify this requirement at intake and advise on the fastest path to obtaining one.

Ground Mount Solar PE Stamps

All Solar Permit Solutions ground mount plan sets are reviewed and wet-stamped by a licensed professional engineer registered in the project state. PE stamping requirements vary by state and system size. See our solar PE stamp requirements by state for jurisdiction-specific thresholds. PE stamping for ground mount systems covers both the structural and electrical engineering elements of the submittal package.

Our PE stamp coverage includes:

• Structural calculations and foundation design letter
• Site plan and equipment layout drawing
• Electrical single-line diagram (SLD)
• Racking and structural framing details
• Grounding and bonding plan
• Interconnection diagram to utility meter or service entrance

We maintain a network of licensed PEs across all 50 states. For most states, the same engineer of record stamps both the structural and electrical drawings, which simplifies the AHJ review process. For state-specific requirements in the largest markets, see our PE stamp requirements for Texas, California, and Florida.

If your AHJ requires a DocuSign or digital stamp rather than a wet stamp, we can accommodate that format. Specify your requirement at intake, and our team will confirm the available format for your state.

Common AHJ Requirements for Ground Mount Permits

Ground mount solar permit requirements vary significantly by jurisdiction. Urban and suburban AHJs tend to require more detailed structural documentation, while rural counties may accept a simpler package. Below are the most common AHJ requirements our team encounters across residential and commercial ground mount projects.

Frequently required by AHJs for ground mount submittals:

• Zoning and land use approval: Many counties require a zoning clearance or conditional use permit before a building permit is issued for a ground mount system. This is separate from the electrical and building permit.
• Setback plan showing distances to property lines: Typically required even if the array is not subject to zoning review. Distances are measured from the array perimeter to the nearest property line, road right-of-way, and structure.
• Utility company interconnection approval: Net metering applications and interconnection agreements must be submitted to the serving utility in parallel with the local permit. The Solar Energy Industries Association (SEIA) tracks state-level permitting and interconnection policy. We can include the utility’s required single-line diagram format if provided.
• Stormwater and grading plan: Required in some jurisdictions for arrays above a threshold size (commonly 10 kW or 1 acre of land disturbance). Federal EPA NPDES stormwater rules apply to construction sites disturbing 1 or more acres. We flag this requirement at project intake.
• Wildlife and environmental clearance: Required in some states for projects on agricultural land or near sensitive habitat. This falls outside our scope, but we can note the requirement in the permit package.
• Rapid shutdown compliance notation: NEC 690.12 rapid shutdown applies to PV circuits installed on or in buildings. Freestanding ground mount arrays that are not attached to a building are generally exempt under NEC 690.12 Exception No. 1 (2023 NEC). If the array conductors enter an occupied building rather than a dedicated PV equipment enclosure, rapid shutdown may apply. Confirm the exemption applies and document it on the plan set. See our NEC 2023 Article 690 guide for full rapid shutdown documentation requirements.
• Canopy and carport variants: Ground-mounted canopy and carport systems involve additional structural and fire code requirements. See our solar carport permit guide for a detailed breakdown of what these projects require.

Our team reviews the applicable state and local codes for each project before completing the plan set. If we identify a requirement that falls outside our standard scope, we will notify you at intake before work begins.

Ground Mount Permit Revisions and Plan Check Response

Plan check corrections are a normal part of the permitting process. Our ground mount permit packages are designed to minimize revision cycles, but when a building department issues a correction notice, we respond quickly to keep your project on schedule.

What is included in our revision support:

• One revision round included: Every ground mount plan set includes one round of plan check corrections at no additional charge, provided the correction items are within the scope of the original submittal.
• Structural recalculation upon request: If the AHJ requests a change to foundation depth, member sizing, or load assumptions, we will revise calculations and reissue the stamped package.
• AHJ correspondence support: If a plan checker raises a question our drawings should have answered, we will draft a response letter explaining the design basis.
• Additional revision rounds: Available at a flat per-round fee. Scope changes (new equipment, different foundation type, layout revision) are treated as a new project.

To initiate a revision, send us the plan check correction letter or written comments from the AHJ. Our team will review the items and confirm turnaround time before beginning the revision.
