How much do solar panels cost in North Carolina?

North Carolina homeowners pay about $2.55/W installed before incentives — roughly $22,950 for a typical 9 kW system. After Duke Energy's a per-watt rebate and any applicable state incentives, the net cost can drop below $20,000. The federal residential tax credit (Section 25D) expired Dec 31, 2025, so 2026+ projects do not receive a federal credit by default.

What solar incentives are available in North Carolina?

Duke Energy offers a $0.40/W residential solar rebate (verify current cap at dsireusa.org) — one of the strongest utility rebates in the Southeast. North Carolina also has full retail-rate net metering in Duke Energy territory. Property tax exemptions apply to solar equipment. Confirm current DSIRE listings at https://programs.dsireusa.org for the latest program funding and eligibility.

Is solar worth it in North Carolina?

Yes — with $0.16/kWh electricity (EIA March 2026), 5.0 peak sun hours, and Duke Energy's retail-rate net metering plus a per-watt rebate, payback typically falls in 7-9 years. If Duke Energy transitions to TOU rates as proposed, self-consumption strategy and battery storage may become more important. Model your actual annual kWh usage for a precise estimate.

Does North Carolina have net metering?

Yes. Duke Energy — the dominant utility serving most of NC — provides full retail-rate net metering. Dominion Energy NC and municipal co-ops like ElectriCities have separate interconnection policies. Confirm your specific utility's current tariff and net-metering rules before sizing a system around exported kWh.

Which utilities serve North Carolina for solar?

Duke Energy is the largest electric utility in NC, followed by Dominion Energy North Carolina and ElectriCities (municipal power agencies). Duke Energy's territory covers Charlotte, Raleigh, Durham, Greensboro, and Winston-Salem. Each utility has different net-metering and rebate rules — Duke's a per-watt rebate applies only in its service area.

What financial incentives still work in NC in 2026?

For 2026+ residential projects: federal Section 25D is expired by default. Focus on Duke Energy's a per-watt rebate, retail net metering, NC property tax exemption for solar, and any local utility programs listed at programs.dsireusa.org. Always verify current program caps and DSIRE listings before purchasing.

North Carolina is a top-5 US solar state — not just for sunlight (5.0 peak sun hours), but because Duke Energy, which serves most of the state, still offers full retail-rate net metering and a $0.40/W residential rebate (verify current cap at dsireusa.org). This combination keeps payback windows at 7-9 years even at $0.16/kWh rates (EIA March 2026). The state's solar manufacturing corridor and Research Triangle policy support add long-term stability. However, Duke Energy has proposed shifting to time-of-use rates, and the rebate pool varies by year. Dominion Energy North Carolina and municipal utilities like ElectriCities serve smaller territories with separate policies — verify your specific utility before relying on statewide averages.

Calculation Method

North Carolina solar payback = net installed cost after incentives / annual avoided electricity cost plus export credits

Key Assumptions

Policy last reviewed: 2026-06-09. Federal residential credit assumptions are project-year dependent and not applied by default for 2026+ projects.
Residential rate and installed-cost figures are planning benchmarks, not a final utility bill audit or installer quote.
The model assumes a roof with usable sun exposure; shading, roof age, electrical upgrades, permitting, and financing can materially change cost.
North Carolina economics should be checked against good solar resource, Duke Energy net-metering transition, and summer cooling load.
The federal tax credit only helps households with sufficient tax liability and qualifying project documentation.
