As of August 2026, home solar in North Carolina runs about $2.50 to $3.00 per watt installed, so a 7 kW system is roughly $17,500 to $21,000 before financing (confirm with local quotes). At the state’s 15.09 cents per kWh power rate, simple payback usually lands near 12 to 15 years because the rate is low. The federal 25D homeowner credit ended December 31, 2025.
North Carolina homeowners pay about 15.09 cents per kWh for electricity (EIA retail sales, residential NC, as of May 2026), one of the lower rates in the country. That is good news for your monthly bill, but it also means each kWh your roof makes is worth less here, so solar payback is longer than in high-rate states. This page walks the cost per watt, the payback math under Duke Energy’s revised net metering, and what changed in 2026. For the full state incentive picture, see our North Carolina solar guide.
According to MySolarFY’s analysis (August 2026), a 7 kW rooftop system in Charlotte (ZIP 28202) produces about 9,910 kWh a year (NREL PVWatts v8), and at North Carolina’s 15.09 cents per kWh residential rate that is roughly $1,495 of grid power you stop buying each year (EIA, May 2026). Raleigh (ZIP 27601) pencils out close behind at about 9,655 kWh. That annual offset is the engine behind the payback below.
How much does solar cost in North Carolina?
Price is quoted in dollars per watt of system size. A typical residential install commonly runs about $2.50 to $3.00 per watt before any incentives. That is a national benchmark, not a North Carolina price filing, so treat the table as a starting point and get itemized local quotes to confirm your own $/W. Your price moves with system size, roof complexity, panel and inverter choice, and the installer.
| System size | Fits a home that uses | Estimated installed cost ($2.50 to $3.00/W) |
|---|---|---|
| 5 kW | Smaller bill, roughly $100 to $140/mo | About $12,500 to $15,000 |
| 7 kW | Average bill, roughly $140 to $220/mo | About $17,500 to $21,000 |
| 10 kW | Larger home or an EV, $220+/mo | About $25,000 to $30,000 |
Cost ranges are a national $/W benchmark for planning, not a guaranteed price. North Carolina excludes 80% of the appraised value of a residential solar electric system from property tax under N.C. Gen. Stat. 105-275(45), so adding panels does not raise your property-tax bill much (DSIRE North Carolina). Confirm your quote before you budget.
What is the solar payback in North Carolina?
Payback is cost divided by what you stop paying the utility. Because North Carolina rates are low, the annual bill offset is smaller than in high-rate states, so payback runs longer even though the sun here is strong. The table pairs the cost above with a production-based offset. Production is the verified Charlotte PVWatts figure scaled by system size, then multiplied by the 15.09 cents per kWh rate.
| System size | Estimated annual production | Estimated yearly bill offset | Simple payback |
|---|---|---|---|
| 5 kW | About 7,079 kWh | About $1,070 | About 12 to 15 years |
| 7 kW | About 9,910 kWh | About $1,495 | About 12 to 15 years |
| 10 kW | About 14,157 kWh | About $2,140 | About 12 to 15 years |
Estimates, not a guarantee. Production is scaled from NREL PVWatts v8 for Charlotte and priced at the current EIA rate. Under Duke Energy’s revised net metering (see below), exported power is credited below full retail, so a home that exports a lot of its production may see payback toward the longer end of this range, and a battery that raises self-consumption can shorten it. Rates, production, and prices vary, so verify your own numbers.
What moves your payback in 2026
Four things decide where you land in that 12 to 15 year window:
- Your electric rate. At about 15.09 cents per kWh, North Carolina power is cheaper than in most states, which is a win for your monthly bill but stretches solar payback because each kWh you offset is worth less (EIA, May 2026).
- Your production. Roof pitch, orientation, and shading swing output. North Carolina gets strong sun, so a 7 kW system makes about 9,910 kWh a year in Charlotte. Estimate yours with NREL’s free PVWatts calculator before you size a system.
- Duke Energy’s revised net metering. Duke Energy Carolinas and Duke Energy Progress closed legacy one-to-one net metering to new residential solar customers after September 30, 2023. New customers now go on a Net Metering Bridge rider or the time-of-use Residential Solar Choice rider, where exports are credited below full retail and a minimum bill and non-bypassable charges apply (verify your rider and terms with Duke before you size a system). For the mechanics, see how net metering credits your solar exports, and for the Duke-specific rates read our Duke Energy North Carolina solar guide.
- No federal credit in 2026. The 30% federal Residential Clean Energy Credit (Section 25D) ended for expenditures made after December 31, 2025, under the One Big Beautiful Bill Act, so a North Carolina homeowner buying with cash or a loan in 2026 cannot claim it (IRS). See what the federal solar tax credit change means in 2026.
The state side is lean, and that is the honest part. North Carolina has no state solar income-tax credit in 2026. The old 35% state renewable energy tax credit expired December 31, 2015, and was not renewed, so leave it out of your math even though older guides still mention it (DSIRE). What remains is the bill offset, net-metering credits, and the 80% residential property-tax exclusion on the system’s value. Duke has also run a solar-plus-storage rebate called PowerPair, but it launched as a limited-capacity pilot, so treat it as verify-before-you-count-on-it: check Duke Energy’s live program page for current 2026 availability rather than assuming a rebate is waiting for you.

How you pay changes the cost you carry
The sticker price is one thing; how you finance it decides your out-of-pocket and your payback.
| How you pay | Up-front cost | Best when |
|---|---|---|
| Cash | Full system price | You want the shortest payback and the most lifetime savings |
| Solar loan | Little or none, financed over time | You want to own the system with low money down |
| Lease or PPA | $0-up-front where you qualify | You want no out-of-pocket cost and a lower or fixed power price without owning |
A lease or PPA has no up-front cost, but the company owns the panels, terms typically run 20 to 25 years and may include an annual escalator, and total payments can exceed a cash purchase. No 2026 North Carolina homeowner gets the federal residential credit, since that credit ended after December 31, 2025.

Frequently asked questions
How much does solar cost in North Carolina?
Installed home solar commonly runs about $2.50 to $3.00 per watt before incentives, so a 5 kW system is roughly $12,500 to $15,000, a 7 kW system is about $17,500 to $21,000, and a 10 kW system is about $25,000 to $30,000. Those are national planning benchmarks, not a North Carolina price filing, so get itemized local quotes to confirm your own dollars per watt.
What is the payback on solar in North Carolina?
At the state’s 15.09 cents per kWh rate, a typical system offsets a modest annual bill, so simple payback usually lands near 12 to 15 years, then years of largely free production follow. A 7 kW system in Charlotte produces about 9,910 kWh a year (NREL PVWatts v8), roughly $1,495 of grid power at today’s rate (EIA, May 2026). Your real payback depends on your quote, your roof, your Duke rider, and how much power you self-consume.
Is there a North Carolina solar rebate or state tax credit in 2026?
There is no North Carolina state solar income-tax credit in 2026; the old 35% state renewable energy tax credit expired December 31, 2015. North Carolina does exclude 80% of a residential solar system’s appraised value from property tax under N.C. Gen. Stat. 105-275(45). Duke Energy has run a PowerPair solar-plus-storage rebate, but it launched as a limited-capacity pilot, so verify current 2026 availability directly with Duke before you count on it.
Does a North Carolina homeowner qualify for the federal solar tax credit in 2026?
Not as a homeowner buying in 2026. The 30% federal Residential Clean Energy Credit (Section 25D) ended for expenditures made after December 31, 2025, under the One Big Beautiful Bill Act, so a cash or loan buyer cannot claim it. A separate commercial credit (Section 48E) can apply to leased and PPA systems, but the business that owns the system claims it, not the homeowner.
How does Duke Energy’s net metering affect payback in North Carolina?
Duke Energy Carolinas and Duke Energy Progress closed legacy one-to-one net metering to new residential solar customers after September 30, 2023. New customers go on a Net Metering Bridge rider or the time-of-use Residential Solar Choice rider, where exported power is credited below full retail and a minimum bill plus non-bypassable charges apply. That lowers the value of exports versus the old rules, so verify your specific rider and rate with Duke before sizing a system.
