What is Solar Permit Design?
Solar permit design refers to the professionally engineered plan sets submitted to local Authorities Having Jurisdiction (AHJs) for approval before installation begins. These plan sets typically include:
-
Site layout and array placement
-
Electrical wiring diagrams
-
Structural mounting details
-
Load calculations
-
Code compliance notes (NEC, IBC, local codes)
Whether you’re submitting for a residential rooftop or a ground-mount commercial farm, a compliant and clear permit plan is non-negotiable.
The Solar Permit Process: Step-by-Step
To understand how to optimize for speed, let’s first break down the typical permit process in the USA:
-
Site Assessment
-
Roof/ground measurements, shading analysis, main panel inspection
-
-
Design Development
-
Electrical layout, system sizing, racking selection, 3D rendering (optional)
-
-
Permit Drawing Creation
-
Full set of engineered drawings prepared using AHJ-compliant templates
-
-
PE Stamps (If Required)
-
Structural or electrical stamps based on state/local requirements
-
-
Submission & Review by AHJ
-
Varies from a few days to weeks based on jurisdiction
-
-
Permit Issued or Returned with Corrections
-
Requires timely and accurate updates if corrections are requested
-
Common Solar Permit Design Mistakes (That Cause Delays)
Delays usually stem from:
-
Missing code compliance information
-
Improper wire sizing or conduit run details
-
Incomplete structural calculations
-
Incorrect AHJ forms or templates
-
No PE stamp when required
Pro Tip: Always check the specific requirements of the AHJ before submitting. Some counties have unique checklists.
Fast Approval Tips: How to Speed Up Solar Permit Design
1. Use a Trusted Permit Design Partner
Working with a reliable solar design service like Eden Solar Design ensures:
-
Accurate layouts tailored to AHJ standards
-
Quick turnaround time (often within 24–48 hours)
-
Seamless integration with PE stamps
2. Standardize Your Input Data
Create a checklist of required data before submitting a new project:
-
Address & system size
-
Panel & inverter specs
-
Roof layout or drone images
-
Main panel photos
-
Battery specs (if any)
3. Always Include NEC 2020 Compliance
More AHJs are adopting NEC 2020. Including updates like:
-
Rapid shutdown
-
AFCI/GFCI
-
Energy storage compliance
4. Pre-Design Proposals Help
Before jumping into full permit design, get a Pre-Design Proposal. It helps catch feasibility issues early and reduces revisions.
5. Stay Updated with AHJ Changes
AHJs often update checklists and formatting requirements. Use a database or subscribe to updates.
PE Stamps: When Do You Need Them?
Structural PE Stamp:
-
For roof-mounted systems (especially over 10kW)
-
Required in wind/snow-prone zones
Electrical PE Stamp:
-
Usually for systems over 50kW
-
Required by utilities or specific AHJs
Eden Solar Design offers both structural and electrical PE stamps across all 50 states.
