Going solar in North Carolina: the process
1. Pick a licensed installer. North Carolina requires installers to hold a NC Electrical Contractor License (Unlimited classification) (Electrical Contractor (Unlimited) + General Contractor) issued by NC State Board of Examiners of Electrical Contractors. Always verify your contractor's license is active before signing.
2. Sign the contract and submit permits. Permit fees and timelines vary by jurisdiction. Charlotte, Raleigh, Durham, and Asheville have streamlined online portals. Typical timeline is 10–20 business days.
3. Installation. Most residential rooftop installs take 1–3 days of on-site work. Your contractor coordinates the timing and any roof staging.
4. Final inspection. The local AHJ inspects your install. Once passed, your installer submits the interconnection application to your utility.
5. Permission to Operate (PTO). Duke Energy Carolinas, Duke Energy Progress, and Dominion all handle residential interconnection under standardized NC processes. Typical PTO within 30–60 days.
Total typical timeline: 6–12 weeks from contract to PTO.

Duke Energy and Dominion Energy (the major NC utilities) offer net metering at full retail for systems under 10 kW residential, with annual true-up. The North Carolina Utilities Commission has approved a successor tariff (Net Energy Metering 2.0 framework) that moves toward time-varying export compensation; legacy NEM customers are typically grandfathered for 15+ years.
