🚫 Common Solar Permit Mistakes in Philadelphia
- Assuming permit approval = can turn system on — need utility PTO separately

- Missing rapid shutdown requirement (NEC 690.12 — required in NEC 2017+ jurisdictions)
💡 Pro Tips from Contractors

- In cities using SolarAPP+, permit can be instant — check if your city uses it before assuming 1-2 week wait
- All disconnects, conduit, and combiner boxes require specific NEC 690 labels — prepare them before final inspection
- Rapid shutdown (NEC 690.12) is required in NEC 2017+ jurisdictions — verify your inverter supports it before installing
