Permit and interconnection checklist
Solar Permit, Interconnection, and PTO Readiness
A good quote should explain more than panels and price. Check whether permitting, utility interconnection, inspection, panel upgrades, roof work, HOA review, and permission to operate are clearly handled.

Permit readiness
Check the hidden steps before signing
Permitting and interconnection are local. This checklist helps you ask the right questions before the contract becomes a timeline problem.
Readiness: watch
This California project has a few permit or interconnection items to verify before signing.
Checklist
- Confirm the authority having jurisdiction (city/county) and utility interconnection process.
- Ask whether the installer handles permit filing, plan set, utility application, inspection, and permission to operate.
- Request the expected timeline from contract to permit approval, installation, inspection, and PTO.
- Verify that the final design includes system size, equipment model numbers, roof attachment method, and electrical one-line diagram.
- If SolarAPP+ availability is unknown, verify the local permitting path with the AHJ or installer.
Ask the installer
- Who submits the permit and interconnection application?
- What must happen before installation can start?
- What happens if the city, county, utility, or inspector requests design changes?
- Is permission to operate included in the projected timeline?
SolarAPP+ and local AHJ rules change by jurisdiction. Use this as a planning checklist, then verify the exact process with the installer, local permitting office, and utility.
SolarCalcNow provides planning estimates only. Results are not installer quotes, engineering designs, tax advice, financing recommendations, or utility interconnection approval.
Source links to verify locally
Check the local authority having jurisdiction and utility interconnection page before relying on installer timeline claims.
SolarAPP+ may speed plan review in participating jurisdictions, but availability and scope should be verified locally.
What to do next
Use permit readiness together with the quote comparison tool. A cheaper quote is not necessarily better if it excludes electrical, roof, interconnection, or inspection work.
