Are solar panels worth it in North Carolina? The honest 2026 answer
North Carolina is a top-5 solar state for good reason: full Duke Energy retail-rate net metering, 80% property tax exemption, and competitive prices. No income credit, but the long-term math works for homeowners with a 15+ year horizon.
North Carolina has been a top-5 solar state by installed capacity for years, and the reason is straightforward: full retail-rate net metering through Duke Energy is far more valuable over 25 years than many other states’ smaller, short-term credits. When you credit every kilowatt-hour of solar production at the retail rate over 25 years, the cumulative value is substantial even at NC’s relatively modest rates of $0.12 to $0.14/kWh.
The honest NC solar case is a long-horizon case. Without a large upfront incentive like NY’s 25% credit or PR’s 25% credit, payback in NC runs 10 to 15 years at today’s rates. But over 25 years, a well-sized Duke Energy net metering system typically delivers $20,000 to $40,000 in net savings. NC homeowners who have lived in their homes for 20+ years and plan to stay know this math — and it is why NC has so much installed residential solar despite no income credit.
NC solar is NOT worth it for homeowners who plan to sell within 5 years, have heavily shaded roofs, or expect the same 5 to 7 year payback of Puerto Rico or New York City. Realistic expectations matter here more than in most states.
