🚫 Common Solar Permit Mistakes in Las Cruces
- Assuming permit approval = can turn system on — need utility PTO separately
- Incorrect labeling — NEC 690 requires specific labels on every disconnect, combiner box, and conduit
- Not accounting for utility interconnection timeline in project schedule (adds 2–8 weeks)
- Missing rapid shutdown requirement (NEC 690.12 — required in NEC 2017+ jurisdictions)
💡 Pro Tips from Contractors
- Start the utility interconnection application the same day you pull the permit — they run in parallel and interconnection often takes longer
- 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
