#5

North Carolina's utility-scale solar market has been a national leader for a decade thanks to historically favourable rate-recovery policies for Duke Energy. The residential market is smaller but growing: around 100,000 residential installations statewide. The 2023 transition from retail net metering to a bridge-rate structure has slowed new residential sales while installers adjust to the new economics.

Incentives

State and local solar incentives in North Carolina

Beyond the 30 percent federal Residential Clean Energy Credit, which applies in every US state through 2032, North Carolina has these state and local programmes.

North Carolina Property Tax Exclusion

Residential solar PV systems are 100 percent excluded from property-tax reassessment under NC General Statute 105-275. Non-residential systems are 80 percent excluded. Automatic.

Duke Energy EnergyWise Home Battery Pilot

Duke Energy residential customers in NC can enroll a home battery in the EnergyWise programme for a one-time incentive plus ongoing bill credits in exchange for allowing utility-controlled discharge during peak events. Programme is capacity-limited.

Pilot programmes for low-income solar

The NC Clean Energy Technology Center and Duke Energy run periodic low-income solar deployment pilots that cover a portion of installation cost for qualifying households. Scope and funding varies year to year.

Permits and interconnection

Permits and interconnection

Permit timelines in North Carolina vary widely by county. Mecklenburg and Wake counties are typically 2 to 4 weeks for residential; some rural counties take longer and require specific inspector trips. SolarAPP+ adoption is minimal in NC. Interconnection with Duke Energy's new solar tariff adds steps compared to the pre-2023 process; expect 4 to 8 weeks post-install for permission to operate.

Running a solar company in North Carolina

Running a solar company in North Carolina means operating in a market that was reshaped by the 2023 net-metering transition. The installers who have grown fastest are the ones who built sales materials explaining Duke's new rate structure to customers and who moved early to solar-plus-battery proposals (because the demand charge gives storage a stronger value than it had under retail net metering). Charlotte, Raleigh and the Triangle are the main metros; Google Ads cost per lead is moderate ($90 to $160 range) and the market is less saturated than the Sun Belt leaders.

Questions people ask

Solar in North Carolina: FAQ

Does North Carolina have net metering?

Not in the retail-rate sense since 2023. Duke Energy residential solar customers are placed on a Solar Choice tariff or Bridge Rate that includes a demand charge, time-of-use energy pricing and a lower export credit than historical retail net metering. The specific credit varies by export time period.

How much does solar cost in North Carolina?

Residential solar in NC averages around $2.60 per watt installed, meaning a typical 7 kW system costs about $18,000 gross. After the 30 percent federal tax credit, net cost is around $12,600. Costs are competitive with other Southern states; higher than Arizona and Texas, lower than New England.

Is solar still worth it in North Carolina?

Yes, with a system sized and configured for the new Duke tariff structure. Payback for residential solar in NC is now typically 10 to 13 years with the federal tax credit, longer than the 7 to 9 years common under the old retail net-metering regime. Pairing solar with a battery to manage the demand charge shortens payback meaningfully in Duke territory.

Does North Carolina have a state solar tax credit?

No. North Carolina had a state solar tax credit until 2015, when it was allowed to expire. The main state-level benefit now is the property-tax exclusion. The 30 percent federal Residential Clean Energy Credit still applies in full.

How many solar companies are in North Carolina?

Roughly 300 to 400 licensed solar contractors operate in North Carolina, concentrated in Charlotte, Raleigh-Durham, Greensboro and the coastal metros. The market is less consolidated than California: the top 10 companies install around 40 to 50 percent of residential volume.
