When Do You Need a Solar Permit?

REQUIRED in all 50 states for solar PV installation

✅ Always Requires a Permit

  • Rooftop solar PV installation of any size
  • Ground-mounted solar arrays
  • Battery storage systems connected to PV
⚠️ When in doubt, pull the permit. The consequences of skipping a required permit — fines, stop-work orders, failed home sales, liability — far outweigh the cost of applying.

🔍 Required Inspections

After the permit is issued, work must be inspected at these stages. Do not cover or close up work before inspection.

  • Rough-in Inspection: Conduit routing, wire sizing, grounding, and electrical rough-in verified before panels are energized.
  • Structural Inspection: Racking attachment to roof structure, flashing around penetrations, load distribution verified.
  • Final Inspection: Full system operational test, proper labeling (NEC 690 requires specific disconnect labels), net meter application confirmed.

🚫 Common Mistakes to Avoid

  • 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

  • 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
  • Document PE stamp requirements before quoting — in FL and some NE states this adds 00-2,000 to project cost
