Do I Need a Permit for a Solar Panel Installation?
Yes — the PV's (the 10kW — the rooftop's; the electrical) needs the building+electrical permits (the structural's — the verified; the interconnected), even where (the expedited — the SolarAPP's). The structural (the 3 psf — the added; the verified), the fire (the 3-foot — the ridge's; the pathways'), and the utility (the interconnection's — the NEM's; the PTO's). The permit's — the sun's paperwork.

The permits
The building (the structural's — the 3 psf's; the verified), the electrical (the 10kW's — the inverter's; the 60A's — the backfeed), the SolarAPP (the expedited — the 1-day's; the DOE's), the fire (the 3-foot's — the ridge's; the pathways' — the 3's), and the utility (the NEM's — the interconnection's; the PTO's — the 2-6 weeks).
The technical's requirements
The 3 psf (the added — the dead's; the verified), the 120% (the busbar's — the rule; the backfeed's), the rapid (the shutdown's — the 1-foot's; the NEC 690.12's), the setbacks (the 3-foot's — the ridge's; the 18-inch's — the valleys'), and the battery (the 80kWh's — the ESS's; the UL 9540's).
Cost
The $25,000-$40,000+ (the 10kW's — the installed; the $2.50-3.50's — the watt), the $500-$1,500 (the permit's — the fees'; the utility's), the 30% (the ITC's — the credit's; the 2026's), and the PTO (the 2-6 weeks' — the permission; the to operate). The sun's — the permitted; the PTO's — the switch.
The bottom line
Rooftop solar needs building + electrical permits (verify 3 psf added dead load, 120% busbar rule, NEC 690.12 rapid shutdown, 3-ft ridge fire setbacks) — use SolarAPP for 1-day permits; budget $500-$1,500 in fees; PTO takes 2-6 weeks.
