Solar in North Carolina costs about $2.76 per watt, so the 9.76 kW system North Carolina homeowners typically install runs about $26,900 before incentives. What you keep depends on your utility: Duke customers who lock the Net Metering Bridge before it closes on December 31, 2026 get far better terms than those left on Solar Choice.

Duke’s Bridge or Solar Choice: the North Carolina rate choice that closes December 31, 2026
Duke Energy Carolinas serves 2.6 million customers, the largest utility in the state. New rooftop customers in Duke territory choose between the Net Metering Bridge (Rider NMB) and the Residential Solar Choice (Rider RSC) time-of-use rate. The Bridge is the better of the two for most homes, and it closes to new applicants on December 31, 2026, under NCUC Docket E-100 Sub 180.
Net Metering Bridge (Rider NMB)
Your monthly use is netted against your production at retail rates. Excess earns the Net Excess Energy Credit, now 3.4¢ per kWh. Lock it before it closes and you keep it for 15 years from your interconnection date.
Residential Solar Choice (Rider RSC)
The default once the Bridge closes. Midday exports earn 3.4¢. Evening use bills at the 21¢ on-peak rate, about six times the export credit and above the 14¢ flat rate. Without a battery, that gap erodes most of the savings.
The interconnection date counts, not the sale dateDuke works through interconnection applications in queue order. To lock the Bridge by year-end 2026, a request needs to be in by late summer or early fall at the latest.
Charges solar cannot erase on the BridgeDuke charges a monthly minimum bill ($22 in DEC territory, $28 in DEP) and a non-bypassable solar fee ($0.36 per kW a month in DEC, $0.44 in DEP).
Dominion and the co-ops: North Carolina meters the Duke deadline never touches
The Duke window does not apply everywhere. Outside Duke territory, the export rule depends on who sends your bill.
Net metering on home systems up to 25 kW. Credits roll over month to month and true up on May 31, when unused credit is forfeited. Application fee: $200 under 20 kW, $750 above.
Dominion EnergyMembers in the western mountains choose retail-rate net metering up to 25 kW, or 5.0¢ per kWh net billing up to 100 kW.
The credit for excess generation.
Avoided-cost net billing, below retail. Municipal utilities are not regulated by the NC Utilities Commission and set their own terms. Check your provider before you sign.
On Dominion, the math runs close to what North Carolina homeowners saw before Duke changed its tariff in 2023: every kWh earns retail credit, so a properly sized system comes closest to the best-case payback and earns credit value for years after.
What each North Carolina tariff does to payback
The typical 9.76 kW system at about $26,900, bought with cash and no federal credit. The export tariff moves payback more than any other factor.
Dominion’s full retail netting and Duke’s Bridge come closest to that best case. On Duke’s Solar Choice without a battery, or co-op net billing at 3¢ to 4¢, exports earn far less than the 14.77¢ you pay, so payback stretches much longer; a battery helps. For your own situation, see whether solar is worth it in North Carolina.
A contractually rising rate works for youExports at 3.4¢ are worth far less than retail power at 14¢ to 17¢. North Carolina’s average home rate rose from 11.3¢ to 14.1¢ per kWh between 2021 and 2024, and Duke’s multi-year rate steps (DEC E-7 Sub 1276, DEP E-2 Sub 1300) run through at least 2026. Duke filed for more 2027 increases in late 2025, still pending at the NCUC.
Up to $9,000 from Duke PowerPair, while slots last
Duke PowerPair is the largest active solar incentive in North Carolina. You must install solar and a battery together through a Duke Trade Ally and enroll in the Bridge or Solar Choice.
PowerPair at its caps
Every active program is in our guide to North Carolina solar incentives.
Duke Energy Progress is full. Duke Energy Carolinas is close.DEP reached program capacity in early 2026 and takes no new applications. On September 24, 2026, Duke Energy Carolinas had less than 10% of its 30,000 kW left. At the 9.76 kW typical system that is room for fewer than 1,000 more homes, first come, first served. If PowerPair is closed for you, the Bridge still works, but the rebate is off the table.
North Carolina quotes from 6 kW to 12 kW, with and without a battery
Quotes in North Carolina run $2.30 to $2.92 per watt, depending on installer, equipment and roof. The EcoGen Index puts the state at $2.76. For context, compare solar costs in all 50 states.
Ranges are quote ranges at $2.30 to $2.92 per watt, mid-2026, before incentives. Battery figures add one 13.5 kWh unit at $13,000 installed. Real quotes vary by roof, equipment and installer.
Competitive price vs. transacted median2024 industry data shows a higher transacted median, $3.50 per watt. That reflects premium equipment and door-to-door sales, not what a homeowner comparing several quotes pays.
Why 9.76 kW is the typical sizeIt is the median size North Carolina homeowners installed in 2025 (Berkeley Lab, 5,650 systems). The state averages 5.25 peak sun hours a day, above the national average, so systems here can be smaller than in the Northeast for the same output.
Coastal wind, mountain shade and permit rules in a North Carolina price
North Carolina sits 4.5% below the national price per watt, 13th lowest of 51. Equipment and labor explain most of a quote; these state factors swing the rest.
+What pushes a North Carolina quote up
- Coastal wind engineeringCoastal counties sit in Wind Zone III under ASCE 7-16, at 110 to 150 mph (Wilmington and the Outer Banks reach 150). Sites at 140+ mph need PE-stamped structural plans and reinforced attachment hardware.
Raises cost against comparable inland work - Mountain sun lossThe Asheville mountains get 4.4 peak sun hours against 5.1 on the coast, a 14% gap. Mountain homes need a slightly larger system for the same output.
- Heavy or layered roofsA PE-stamped plan is also required where panels add more than 3 psf or the roof has multiple shingle layers.
- PermitsA separate electrical permit is always required under N.C.G.S. 87-43.
$100 to $500 in fees
−What works in your favor
- Piedmont sunWhere most North Carolinians live, sun runs above the 5.25-hour state average (NREL PVWatts).
- Quick permitsMost jurisdictions issue permits in 3 to 10 business days, with Raleigh among the faster cities.
- HOA protectionUnder G.S. 22B-20, HOAs cannot ban solar. Limits costing under 5% of the price or cutting output under 10% are allowed, and so are limits on street- or common-area-facing placement. The NC Supreme Court upheld these rights in Belmont Ass’n, Inc. v. Farwig (2022).
The North Carolina breaks left after §25D
The 30% federal credit is gone for systems you buyThe Section 25D credit ended for systems completed after December 31, 2025, under the One Big Beautiful Bill Act, with no phasedown and no grandfather provision. A $25,000 system that earned $7,500 back in 2025 earns nothing in 2026. At $2.76 per watt, that loss is 30% of the price of any system you buy.
Under G.S. 105-275(45), 80% of appraised value is excluded, and home systems not used for business are not taxed at all. No expiry date.
NC General AssemblyOpen for projects placed in service through 2027, or under construction by July 4, 2026 under safe-harbor rules (that date has passed). The lessor claims it and passes some value through as a lower monthly rate.
Solar plus a battery through a Duke Trade Ally, while program capacity lasts.
Six North Carolina homes where the numbers fail
Solar pays only when the rest of the picture supports it. For most homeowners here, these cases do not work:
- Duke Solar Choice with no battery. The 3.4¢ export credit against peak evening rates pushes cash payback far past the best case, longer with a loan. If you cannot add a battery, the system is not worth installing.
- Co-op or city net billing at avoided cost. At 3¢ to 4¢ per kWh (Blue Ridge offers 5.0¢), exported power loses most of its value. A system that uses 95% of its own output can still work, on a thin margin; a battery helps.
- Mountain sites with 4.4 sun hours and heavy shade. Some Asheville-area sites never pay off in 25 years.
- You plan to move within 5 years. Without the federal credit, the payback does not fit a short stay. Lean toward a lease, or wait.
- Your roof needs replacing within 5 to 7 years. Removing and reinstalling panels is a real cost that panel warranties do not cover. Re-roof first.
- You use under 500 kWh a month. That is less than half the 1,015 kWh state average. Minimum bills and fixed charges erode the savings.

Five questions that show whether a North Carolina installer knows Duke
These state-specific questions separate a competent North Carolina installer from a national operator selling a generic package:
- What is your NC electrical contractor license number? Every install needs a licensed contractor under N.C.G.S. 87-43 (Limited, Intermediate or Unlimited).
- Are you a registered Duke Trade Ally for PowerPair? An installer not on Duke’s list cannot file the rebate paperwork.
- What is your current interconnection lead time with Duke or Dominion? To lock the Bridge before December 31, 2026, the interconnection date is what counts.
- Will the system carry PE-stamped structural plans? Required in 140+ mph wind zones, on multi-layer roofs and above 3 psf.
- How are you sizing the battery for Solar Choice TOU? If Solar Choice is your only option, battery sizing drives the payback.

North Carolina guides for the next step
Frequently asked questions
How Much Do Solar Panels Cost in North Carolina in 2026?
A residential solar system in North Carolina runs about $2.76 per watt installed, so the typical 9.76 kW system costs about $26,900 before incentives. Quotes put most 8 kW systems in the $18,400 to $23,400 range. Larger homes or all-electric households pay $23,000 to $35,000 for a 10 to 12 kW system. Adding a 13.5 kWh battery raises the cost by $13,000.
Can I Still Get the 30% Federal Tax Credit?
No, not for a cash or loan purchase. Section 25D ended for systems whose installation is completed after December 31, 2025. The only way to access a federal benefit on a 2026 install is through a solar lease, where the lessor claims the Section 48E commercial credit and passes some of that value through as a lower monthly rate.
What Happens If I Miss the Duke Net Metering Bridge Deadline?
New Duke customers who interconnect after December 31, 2026 default to the Residential Solar Choice TOU rate. Under Solar Choice, midday exports credit at 3.4 cents per kWh while evening usage bills at a peak retail rate. That gap makes a battery part of the system rather than an optional upgrade for the math to work.
Is PowerPair Still Available in My Duke Territory?
Duke Energy Progress reached program capacity in early 2026 and is no longer accepting new PowerPair applications. Duke Energy Carolinas had limited capacity remaining as of early 2026 and is filling slots first-come, first-served. Verify status with a Duke Trade Ally installer before counting on the rebate.
Does Solar Pay Off for Dominion Energy Customers?
Yes, in most cases. Dominion’s full retail 1:1 net metering on residential systems up to 25 kW means every kWh you export earns the same value as a kWh you consume. Best-case payback is about 13.3 years without the federal credit, if every kWh the typical 9.76 kW system makes replaces power at the 14.77¢ state average, and full retail netting keeps Dominion homes closer to that than Duke or co-op homes. Years of nearly free electricity follow.
Do I Need a Battery for Solar to Work on Solar Choice TOU?
In practice, yes. The 3.4 cent export credit combined with peak evening retail rates means a system without storage gives up most of its value on Solar Choice. A battery sized to cover evening consumption (10 to 13.5 kWh for most homes) turns the export gap into a self-consumption gain.
Will My HOA Block a Solar Installation?
Under G.S. 22B-20, North Carolina HOAs cannot ban residential solar outright or impose restrictions that exceed 5% of the system cost or reduce efficiency by more than 10%. HOAs can restrict street- or common-area-facing placement, but they cannot prevent a roof system that meets these constraints.
How Long Does Permitting and Interconnection Take?
Permit approval runs 3 to 10 business days in most North Carolina jurisdictions, with Raleigh among the faster cities. Duke interconnection adds further time after permitting, and the queue lengthens through Q4 as customers race the Bridge deadline. To lock the December 2026 cutoff, file an interconnection request by late summer.
Does North Carolina Tax the Added Value Solar Brings to My Home?
No. Under G.S. 105-275(45), 80% of the appraised value of residential PV is excluded from property tax, and residential systems not used for a business are treated as non-business personal property that is not taxed at all. The exemption holds for the life of the system.
How we calculate these costs
Cost figures use the EcoGen Solar Cost Index (September 2026 Edition): North Carolina’s installed price per watt, built from the Department of Energy’s cost benchmark adjusted for local labor wages, run through our cost model, calibrated against current marketplace quotes and checked against installed prices from Berkeley Lab. Quote ranges come from EcoGen’s installed-cost references, built on Berkeley Lab’s Tracking the Sun, the DOE/NREL benchmark and SEIA/Wood Mackenzie data. The typical system size is Berkeley Lab’s 2025 median for North Carolina single-family installs (5,650 systems); the typical cost is that size times the price per watt. The best-case payback divides that cost by the year-one value of the system’s output at the 14.77¢ state average (EIA, August 2025 to July 2026), with no federal credit and no rate growth. Real quotes vary by roof, equipment and installer.
