Solar permit plans in California
A strong California solar permit package brings the roof, structure, electrical connection, and selected equipment into one coordinated set.

Engineering around the real project
California projects span different utilities, building types, and local review paths. We confirm the property address and installation scope first, then develop the drawings and engineering details needed for that project.
The drawing package can include a site and roof plan, module layout, electrical single-line diagram, equipment schedule, and mounting details. Structural or electrical professional review is added when the project scope requires it.
We identify the local authority and serving utility from the project address. That keeps the plan set tied to the proposed installation rather than a broad regional assumption.

From intake to a coordinated set
What we prepare together
The sheet list depends on the installation, but these are the core questions we work through.
How it connects
Selected modules, inverter, disconnects, conductors, storage, and proposed point of connection coordinated in a single-line diagram.
How it is mounted
Attachment or foundation details, product data, and supporting structural information as the scope requires.
Before we begin
Common project questions
Good scoping prevents drawing changes after equipment has been selected.
Can the plan include a battery or service upgrade?
Yes. Tell us the battery model, desired backed-up loads, existing service rating, and proposed equipment changes so those elements can be coordinated from the first electrical diagram.
Do all properties in California use the same permit route?
No. The applicable authority and utility can vary by exact address and project type. We confirm both while defining the scope.
What is needed for an initial review?
Start with the address, photos of the proposed installation area and service equipment, a utility bill, and the equipment list if available. Existing plans are helpful for retrofits and larger buildings.
