Short answer

Solar panels in North Carolina cost about $20,800 installed for an 8 kW system, roughly $2.60 per watt. That is also the net cost — there is nothing left to subtract. The 30% federal homeowner credit ended for systems placed in service after December 31, 2025, so it is not in any number here. At 13.5¢ per kWh, the system offsets about $1,482 of electricity a year and pays for itself in 14.0 years.

Modelled from EIA rate data and NREL sun hours for North Carolina, not a quote. No federal homeowner credit is assumed, because there is not one. If a quote you are holding subtracts 30% and calls it a federal credit, that quote is wrong.

Cost by system size in North Carolina

Most North Carolina homes land between 6 and 10 kW. The right size is the one that covers your own annual kWh, not the biggest array the roof will hold — production beyond what you use is credited at whatever your utility pays for exports, which is almost never the retail rate.

Modelled, not quoted. Production is system size × 4.7 peak sun hours × 365 days × 0.8 for inverter, wiring, soiling and heat losses. Savings value that production at 13.5¢ per kWh and hold the rate flat for year one. Panel count assumes 400 W modules. Your roof, your shade and your usage move all of it.

No federal credit is in these numbers. The 30% homeowner credit (IRC Sec. 25D) ended for systems placed in service after December 31, 2025. Net cost above is gross cost minus whatever state or local money is still open — nothing else. If a quote knocks 30% off and calls it a federal credit, ask which statute they are citing.

Electricity rates in North Carolina

North Carolina households pay 13.5¢ per kWh on average. That single number does more to decide whether solar works here than anything an installer will tell you, because solar is not a product you buy — it is electricity you prepay. If the rate is high, prepaying is a good trade. If it is low, it is not, and no amount of financing changes that.

North Carolina residential rate (EIA average)13.5¢ / kWh
Modelled annual rate escalation2.9% / yr
Rate in 10 years at that escalation18.0¢ / kWh

Rate is EIA’s statewide residential average, which blends every utility and every tariff in North Carolina — your own bill will differ. The escalation figure is modelled from North Carolina’s own EIA price history and compounded forward; it is an assumption, not a forecast. The ten-year figure is arithmetic on that assumption, nothing more.

How long solar takes to pay for itself in North Carolina

About 14.0 years for an 8 kW system, holding the rate flat. $20,800 net cost divided by $1,482 of electricity offset in year one. No federal credit is in that, because there is not one to put in it.

Holding the rate flat is the conservative version. Let it rise at the 2.9% modelled above and payback shortens, because the electricity you are not buying gets more expensive every year. Neither version accounts for an inverter replacement somewhere around year twelve to fifteen, which is a real cost most quotes leave out.

Is solar still worth it in North Carolina without the federal credit?

It is a slower bet than it was. An 8 kW system in North Carolina costs $20,800 net, offsets about $1,482 in year one, and takes about 14.0 years to pay back with no federal credit in the maths at all.

Here is the honest version of what changed. The credit used to cover 30% of the cost, so losing it stretches payback by roughly 30% too — a system that paid back in eight years now takes closer to eleven. Nothing else moved. The panels produce the same kWh, North Carolina still averages 4.7 peak sun hours, and you still pay 13.5¢ per kWh for the power you would otherwise be buying.

That last number is the one that actually decides it. Solar is a prepayment on twenty-five years of electricity at a fixed price. The subsidy only ever changed how much you prepaid. If your rate is high and rising, the case survives the credit ending; if it is low, the credit was probably carrying the deal, and the right answer now may be no.

North Carolina has no state program to absorb any of that, which is why the numbers above are the whole story. Two things to watch as installers adjust: cash prices should come down as demand softens, and lease and PPA pitches will get more aggressive, because the business-side credit the financier claims is still alive. A lease is not a credit you receive.

Incentives in North Carolina

Federal

The homeowner credit is gone

On an 8 kW system here$0

The Residential Clean Energy Credit under IRC Sec. 25D ended for property placed in service after December 31, 2025. A system going up in North Carolina today claims none of it. Nothing about that is specific to North Carolina — it is federal, and it applies everywhere.

Two things installers say that are not the same as a homeowner credit. One: business-side credits still exist, which is why lease and PPA pitches got louder — that credit goes to the financier, not to you, and what you get back is whatever they price into the contract. Two: “placed in service” is not the same as signed, paid or scheduled. If a salesperson is still subtracting 30% on a proposal for a 2026 install, ask them to write the statute number next to the line.

State

No state-level incentive in North Carolina

North Carolina runs no state rebate or state tax credit for residential solar. With the federal homeowner credit also gone, the honest position is that there is no subsidy here at all. The $20,800 above is the whole price, and the 14.0-year payback is what it looks like unsubsidised.

What is left doing the work is your 13.5¢ rate, the 4.7 sun hours and your utility’s net metering terms. Individual utilities sometimes run small rebates that never make the statewide lists — the ones operating here are Duke Energy Carolinas, Duke Energy Progress, Dominion Energy North Carolina, Blue Ridge Energy, and DSIRE is searchable by utility name. Anything you find there is upside on top of the numbers above, not baked into them.

Net metering in North Carolina

North Carolina moved Duke Energy customers onto time-of-use net billing in 2023, so export value now depends heavily on when your panels produce.

Net metering is the single rule that decides what your daytime overproduction is worth. Full retail credit means every exported kWh cancels an imported one at the same 13.5¢; anything less means exports are bought at a lower rate and the payback stretches. It is the first thing to ask any installer to put in writing, because the terms you sign up under are usually locked for a set number of years.

Utilities operating in North Carolina: Duke Energy Carolinas, Duke Energy Progress, Dominion Energy North Carolina, Blue Ridge Energy.

Questions North Carolina homeowners ask

How much do solar panels cost in North Carolina?

Solar panels in North Carolina cost about $20,800 installed for a typical 8 kW home system — about $2.60 per watt. That is also what you pay. The 30% federal credit ended for systems placed in service after December 31, 2025, and North Carolina runs no statewide program, so there is nothing to subtract. Smaller 6 kW systems land near $15,600 and larger 10 kW systems near $26,000, before any incentive.

Is solar still worth it in North Carolina without the federal tax credit?

It is a longer bet than it was — payback runs about 14.0 years with no federal credit at all. What actually decides it in North Carolina is the 13.5¢ per kWh you pay now and the 4.7 peak sun hours the state averages. The credit ending pushed payback out by roughly the same 30% it used to cover; it did not change the electricity price, which is the thing you are really buying out of.

Did the 30% federal solar tax credit end?

For homeowners, yes. The Residential Clean Energy Credit under IRC Sec. 25D ended for property placed in service after December 31, 2025. A system going on a North Carolina roof now claims $0 of it. Business-side credits are a different part of the code and are not a homeowner credit no matter how a lease or PPA salesperson describes them.

What incentives are available in North Carolina?

None worth the name. North Carolina runs no statewide residential rebate or tax credit, and the federal homeowner credit ended for systems placed in service after December 31, 2025. Individual utilities occasionally run small rebates that never reach the statewide lists — search DSIRE by your own utility name (Duke Energy Carolinas, Duke Energy Progress, Dominion Energy North Carolina, Blue Ridge Energy). Everything above assumes zero subsidy, so a utility rebate can only improve it.

How many solar panels does a house in North Carolina need?

About 20 panels for an 8 kW system at 400 W each, producing roughly 10,979 kWh a year in North Carolina sun. If your annual usage is higher than that, size up; net metering rules usually make it pointless to build past your own consumption.

What is the average electricity rate in North Carolina?

13.5¢ per kWh for residential customers, on EIA's statewide average. That is the number solar competes with: every kWh the array makes is a kWh you do not buy at 13.5¢. Our 25-year model escalates it at 2.9% a year, taken from North Carolina's own EIA price history — a modelled assumption, not a forecast anyone can guarantee.

Does North Carolina have net metering?

North Carolina moved Duke Energy customers onto time-of-use net billing in 2023, so export value now depends heavily on when your panels produce. Whatever the state rule says, the terms that bind you are your own utility's — Duke Energy Carolinas, Duke Energy Progress, Dominion Energy North Carolina, Blue Ridge Energy — and municipal utilities and cooperatives are usually outside the state rule entirely.
