solar troubleshooting
Interconnection or inspection failed
Common symptoms: solar inspection failed; interconnection rejected; pto delayed; utility correction notice
Stop and call a pro if:
- Do not energize/export before permit and utility approval
- Follow AHJ and utility correction list exactly
Step-by-step diagnostic flow
Step 1
Is the failure from AHJ inspection, utility interconnection review, or both?
Step 2
Did the notice cite labeling/placards, disconnect access, or plan mismatch?
Step 3
Did utility request missing forms, inverter certification, or one-line revisions?
Possible outcomes

high confidenceMost first-pass failures are labeling, access, and as-built mismatches.
- Update labels/placards and plan set
- Photograph corrections
- Reschedule inspection
Technical AHJ correction requires installer/engineer review
medium confidenceStructural/electrical design comments need professional resubmittal.
- Escalate to installer engineering package
- Submit stamped revision where required
Utility packet incomplete — update and resubmit
high confidenceUtility rejection commonly follows missing forms or certification attachments.
- Resubmit complete packet
- Confirm receipt with utility queue
Utility technical hold — coordinate installer and utility engineer
medium confidenceGrid-side constraints or protection requirements can block approval.
- Coordinate revised one-line/protection docs
