North Carolina has been a top-five solar state for years, but the residential side of the business here has always run on lead flow rather than on policy tailwinds. That's more true in 2026 than it has ever been.

What SB 266 changed for the residential installer
SB 266, passed in 2025 over a veto, rolled back the state's interim carbon-reduction targets. SEIA notes analysts expect the change to shift more cost onto residential customers over time. For an installer, rising residential rates are a selling point — but only if you're in front of the homeowner at the moment they're already spending money on the house.
The permit signals that actually predict a solar sale
- Reroof permits. A homeowner who just paid for a new roof has a 20-year surface and no reason to wait — and you avoid the remove-and-reinstall conversation.
- Electrical service upgrades to 200A. Panel work is the most reliable precursor to PV and storage in NC records.
- New single-family permits in Wake, Durham, and Chatham. Solar-ready conduit at framing is far cheaper than a retrofit, and builders will talk if you reach them at permit stage.
- Existing PV permits by street. Solar clusters. One installed system in a Cary cul-de-sac is the best predictor of the next three.
Storage is the upsell hiding in the data
NC ranks 18th in storage against 5th in solar — that gap is the addressable market. Every PV permit filed in Raleigh or Durham three-to-eight years ago is a battery retrofit candidate today, and those addresses are public.
