From ensuring code compliance to preventing costly installation delays, a good permit design isn’t just paperwork — it’s project insurance. While PV modules and inverters get the spotlight, it’s the permit design process that ensures your system ever sees the light of day (legally). Whether you’re a solar installer, EPC, or project developer, your timelines and margins can be made — or broken — by the quality of your permit design.

What Is Solar Permit Design?
A solar permit design is a comprehensive plan detailing how a solar panel system will be installed, ensuring it meets safety standards and local building codes, it include:

Site plan & layout
Electrical diagrams
Structural calculations
Code compliance notes (NEC, local amendments)
Mounting and racking details
In other words, it’s your solar system — on paper — in a format that local authorities understand and approve.

Why Plan Set Matters?
A clear, accurate plan speeds up the permitting process = Fast Approvals.
Avoid Redesigns – Incorrect AHJ compliance = resubmissions ...
... and wasted time.
A solid plan reduces confusion in the field, saving time and preventing errors = Installer Confidence.
Client Trust – A streamlined permit process reflects professionalism, builds trust, and reduces cancellations.
The Hidden Cost: Revisions
The average cost and price for solar permit design in the USA typically ranges from $100 to $150 for complete plan sets (0-15 kW). Revisions are often unavoidable. A client might change panel placement. A roofer may find unexpected structural issues. The AHJ might require clarification.

The problem? Many design firms charge $50–$200 per revision — adding up fast for solar professionals working on tight margins.
