How Much Does Solar Cost in North Carolina?
Installed prices for homeowner-purchased residential solar in North Carolina run between $2.30 and $2.92 per watt, depending on installer, equipment, and complexity, with a competitive market midpoint of $2.61 per watt. That figure is what a homeowner shopping with multiple quotes can expect to pay. The higher transacted median reported in 2024 industry data ($3.50 per watt) reflects premium-equipment sales and door-to-door channels rather than the current competitive market.
Most North Carolina households use 12,180 kWh per year, which under the state’s 5.25 daily peak sun hours points to a system in the 7 to 9 kW range. Here is how the price breaks down by system size:
System Size | Solar Only (Before Incentives) | Solar Plus 13.5 kWh Battery | Best Fit |
|---|---|---|---|
6 kW | $13,800 – $17,500 | $26,800 – $30,500 | Small home or partial offset |
8 kW | $18,400 – $23,400 | $31,400 – $36,400 | Average North Carolina home |
10 kW | $23,000 – $29,200 | $36,000 – $42,200 | All-electric home, EV, or heat pump |
12 kW | $27,600 – $35,100 | $40,600 – $48,100 | Larger home or full offset goal |
Pricing reflects the competitive market in mid-2026. Real quotes vary by roof complexity, equipment selection, and installer. Battery cost reflects the North Carolina installed rate that puts a 13.5 kWh battery at $13,000.
Sizing note. North Carolina’s 5.25 daily peak sun hours sit above the national average, so systems here do not need to be as large as those in Northeastern states to produce the same annual output. A 7.7 kW system covers the average household’s full annual consumption, and 8 kW is the nearest standard sizing tier above that figure.
Duke’s Net Metering Bridge Closes December 31, 2026, and It Sets Your Price
Which export tariff your utility puts you on changes NC payback more than any other factor.
Duke Energy Carolinas serves 2.6 million customers and is the largest electric utility in the state. New rooftop solar customers in Duke territory choose between two rate plans: the Net Metering Bridge (Rider NMB) or the Residential Solar Choice (Rider RSC) time-of-use rate. The Bridge is the better of the two for most homeowners, and it closes to new applicants December 31, 2026, under NCUC Docket E-100 Sub 180.
Under the Bridge, your monthly usage is netted against your solar production at retail rates, with any excess credited at the Net Excess Energy Credit, currently 3.4 cents per kWh. Duke also charges a monthly minimum bill ($22 in DEC territory, $28 in DEP) and a non-bypassable solar fee ($0.36 per kW per month in DEC, $0.44 per kW in DEP). Customers who lock the Bridge before it closes keep that rate for 15 years from their interconnection date.
Miss the deadline, and Solar Choice TOU becomes the default option. Solar Choice credits midday exports at the same 3.4 cents per kWh while billing your evening usage at the time-of-use on-peak rate of 21 cents per kWh, six times the export credit and above the 14-cent flat rate a non-TOU customer pays. Without a battery to shift that midday production into evening consumption, the gap erodes most of the savings a solar system would otherwise deliver. The deadline is set by NCUC order in Docket E-100 Sub 180.
⚠️ Practical timing. Duke processes interconnection applications in queue order, not by sale date. To lock the Bridge by year-end 2026, an interconnection request needs to be submitted in late summer or early fall at the latest. Installers booked into Q4 are already turning away new contracts in some service areas.
Why Dominion and Cooperative Customers See Different Math
The Duke window does not apply everywhere. Dominion Energy North Carolina, which serves the northeastern part of the state, still offers full retail 1:1 net metering on residential systems up to 25 kW. Excess kWh credits roll over month to month and true up annually on May 31, with any unused credit forfeited at that point. Dominion charges a $200 application fee for systems under 20 kW, and $750 for larger systems.
If you are on Dominion, the payback math runs closer to what North Carolina homeowners saw before Duke restructured its tariff in 2023. A properly sized system in Dominion territory recovers its cost in 10 to 13 years and produces excess credit value for two decades after that.
The cooperative and municipal picture varies. Blue Ridge Energy, which serves the western mountains, gives members a choice between retail-rate net metering on systems up to 25 kW and a 5.0 cent per kWh net billing option on systems up to 100 kW. EnergyUnited credits excess generation at 3.3 cents per kWh. Most other cooperatives default to avoided-cost net billing in the 3 to 4 cent range, below retail. Municipal utilities are not regulated by the NC Utilities Commission and set their own terms; verify your specific provider before signing a contract.
PowerPair: The $9,000 Rebate Race in Duke Territory
Duke PowerPair is the largest active solar incentive in North Carolina. Duke pays $0.36 per AC watt for solar (capped at 10 kW, or $3,600) and $400 per kWh for battery storage (capped at 13.5 kWh, or $5,400), for a maximum combined rebate of $9,000. The program requires installing solar and battery together through a Duke Trade Ally and enrolling in either the Bridge or Solar Choice tariff.
The capacity reality is the catch. Duke Energy Progress reached its program capacity in early 2026 and is no longer accepting new applications. Duke Energy Carolinas had 7,210 kW of capacity remaining as of February 2026, which at the state’s 7.7 kW average residential system size leaves room for fewer than 1,000 more enrollments. Slots are filled first-come, first-served, and verified Trade Ally installers do most of the application work.
If PowerPair is still available in your territory and you are pairing solar with a battery, this incentive cuts up to $9,000 off the installed cost, the single largest reduction still available in 2026. If it is closed, the economics still work in Bridge territory, but the headline rebate is no longer on the table. For complete breakdown of every active North Carolina solar incentive in one place, see our incentives guide.
Without §25D, a 2026 NC Cash Buyer Loses $5,000 to $8,000 of Year-One Value
The 30% federal Residential Clean Energy Credit under Section 25D ended for systems placed in service after December 31, 2025. North Carolina homeowners who purchase a system with cash or a loan in 2026 cannot claim it. The One Big Beautiful Bill Act terminated the credit outright, with no phasedown and no transition period. The IRS has confirmed there is no grandfather provision for residential purchases.
One opening remains. The commercial Section 48E credit, which can still reach a 30% value, stays active for projects placed in service through the end of 2027 (or under construction by July 4, 2026 under safe-harbor rules). That credit reaches residential systems only through third-party ownership: a solar lease or a power purchase agreement. The lessor or PPA provider claims the credit and passes some of that value through to the homeowner as a lower monthly rate.
For 2026, this changes the comparison between cash and lease in North Carolina materially. A cash purchase that would have netted a $7,500 federal credit on a $25,000 system in 2025 now nets zero. That year-one loss runs from $5,000 on a 6 kW system up to $8,000 on a 10 kW system, 30% of installed cost in 2025. A lease in the same scenario carries the federal benefit indirectly, which is why third-party offers have gained relative ground in 2026 even where outright ownership still delivers the better long-term value.
Coastal Wind Engineering, Mountain Sun Loss, and the G.S. 105-275 Tax Exemption
Equipment and labor pricing tell most of the story, but several state-specific factors swing the per-watt figure beyond what a national average would suggest.
Wind engineering. Coastal counties fall into Wind Zone III under ASCE 7-16, with design wind speeds from 110 to 150 mph (Wilmington and the Outer Banks reach 150 mph; Piedmont sites run 100 to 110 mph). Systems in 140+ mph zones require PE-stamped structural plans and reinforced attachment hardware. That engineering raises the installed cost of a coastal system relative to comparable inland work.
Mountain production loss. North Carolina averages 5.25 daily peak sun hours statewide (NREL PVWatts), highest across the Piedmont, where most North Carolinians live and where it runs above that 5.25 figure, then 5.1 on the coast and 4.4 in the Asheville mountains. The 14% gap between coastal (5.1) and mountain (4.4) output means mountain installs need a slightly larger system to deliver the same annual output, which raises the gross cost.
Permitting. Most North Carolina jurisdictions issue residential solar permits within 3 to 10 business days, with Raleigh among the faster cities. A separate electrical permit is always required under N.C.G.S. 87-43, and a PE-stamped plan is required where PV adds more than 3 psf, where the roof has multiple shingle layers, or in 140+ mph wind zones. Permit fees run $100 to $500.
Property tax. Residential PV in North Carolina is functionally exempt from property tax. Under G.S. 105-275(45), 80% of the appraised value is excluded from the tax base, and residential systems not used for business are treated as non-business personal property and not taxed at all. This holds for the life of the system, with no expiration.
HOA limits. Under G.S. 22B-20, North Carolina HOAs cannot ban residential solar or impose unreasonable restrictions. Reasonable restrictions, defined as those costing under 5% of the system price or reducing efficiency by under 10%, are still permitted. HOAs can also restrict street- or common-area-facing placement. The North Carolina Supreme Court upheld these rights in Belmont Ass’n, Inc. v. Farwig in 2022.
Why the Duke Bridge Beats Solar Choice TOU on NC Payback
Payback figures from a national source rarely match what a North Carolina homeowner sees, because Duke’s tariff structure changed everything in 2023 and the federal credit changed everything again in 2026. Here is what an 8 kW system at $20,900 looks like by territory:
Utility Territory | Export Credit | Realistic Payback (No §25D) | Best Available Lever |
|---|---|---|---|
Duke (DEC/DEP), on Bridge | Net metered at retail, excess at 3.4¢/kWh | 11 to 14 years; $20,000 to $28,000 net 25-year savings | PowerPair if still open in your territory |
Dominion Energy NC | Full retail 1:1 net metering | 10 to 13 years; $22,000 to $30,000 net 25-year savings | Property tax exemption and stable tariff |
Duke, on Solar Choice TOU | 3.4¢/kWh exports, peak retail consumption | Below break-even to ~$10,000 net over 25 years without a battery; competitive with one. | Battery for self-consumption |
Cooperative net billing | 3 to 4¢/kWh, Blue Ridge 5.0¢ | Below break-even to ~$10,000 net over 25 years without a battery; better with one. | Battery for self-consumption |
Three factors explain the spread. Exports at 3.4 cents have nowhere near the value of retail kWh at 14 to 17 cents, so any system that pushes a large share of its production back to the grid suffers under Solar Choice. North Carolina’s average residential rate rose from 11.3¢ to 14.1¢ per kWh between 2021 and 2024, with Duke’s multi-year-plan stair-steps (DEC E-7 Sub 1276 and DEP E-2 Sub 1300) locked in through at least 2026 (Duke filed proposals for additional 2027 increases in late 2025, still pending NCUC approval). A system installed today is hedging against a rate that is contractually rising. Even without the 30% federal credit, North Carolina’s property tax exemption and the state’s 5.25 daily peak sun hours support a workable 25-year return for homeowners on favorable tariffs.
For a deeper look at whether solar is worth it in North Carolina under your specific situation.
HB 589 Leases vs Cash in 2026 North Carolina
Without the federal credit on purchases, the four ways to finance solar in North Carolina look different than they did 12 months ago.
Cash purchase still delivers the strongest 25-year return for homeowners on Bridge or Dominion tariffs. You own the system, you collect the property tax exemption, and you keep every kWh of self-consumption value. The trade-off is the higher upfront commitment now that no 30% credit reduces the first-year cost.
Solar loans remain available through credit unions and national lenders. Without the federal credit to apply as a Year 1 lump-sum payment, the monthly note runs higher than 2025 projections would have suggested. Verify that your loan payment is lower than the utility bill it replaces. If it is higher, the loan defers cost rather than saving it.
Solar leases have gained relative ground in 2026 because they are the way North Carolina homeowners can access a federal benefit. Under HB 589 (2017), North Carolina permits solar leasing through a registered third-party leasing structure, with 12 lessors holding NCUC certificates as of early 2026. The lessor claims the Section 48E commercial credit and passes some of that value through as a lower monthly rate.
Power purchase agreements (PPAs) are still legally restricted in North Carolina by the state’s utility monopoly law, though HB 589 covers most of the same use case through its leasing structure. Read every contract for escalator clauses, transfer terms, and what happens to the lease when you sell the home. For a fuller look at how $0-down solar offers work in North Carolina.
Where Solar Choice TOU, Mountain Shading, or a 5-Year Move Kills NC Payback
A solar system delivers value only when the rest of the picture supports it. In North Carolina, these are the situations where the math will not work for most homeowners:
Duke Solar Choice TOU without a battery. The 3.4 cent export credit combined with peak evening retail rates pushes payback past 15 years for cash buyers, and longer for loan customers. If your only option in Duke territory is Solar Choice and you cannot afford a battery to self-consume your production, the system is not worth installing.
Cooperative or municipal customers on avoided-cost net billing. Where excess generation credits at 3 to 4 cents per kWh (Blue Ridge offers a 5.0¢ option), a system sized to produce excess will lose most of that value. A right-sized system that consumes 95% of what it produces can still work in this case, but the margin is small and a battery improves it materially.
Mountain sites with 4.4 sun hours and significant shading. A 14% production gap relative to the coast, plus tree shading, can further reduce output. Some Asheville-area sites do not produce enough to make any system pay off in 25 years.
Imminent move. Without the federal credit, the 25-year payback profile no longer compresses well into a 5-year ownership window. Homeowners planning to move within five years should lean toward leasing or wait until they settle into a longer-term home.
Roofs needing replacement within 5 to 7 years. Removing and reinstalling panels mid-system-life is a real expense and is not covered by panel warranties. Replace the roof first, or wait until a re-roof is planned and install at the same time.
Very low household consumption. Households using under 500 kWh per month, less than half the 1,015 kWh state average, see minimum bills and non-bypassable charges erode their savings to where a system rarely recovers its cost.
N.C.G.S. 87-43 License, Duke Trade Ally, and the Interconnection-Queue Question
A handful of 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 solar installation requires a licensed contractor under N.C.G.S. 87-43; the North Carolina Board of Examiners of Electrical Contractors lists Limited, Intermediate, and Unlimited tiers.
- Are you a registered Duke Trade Ally for PowerPair? Trade Ally status is required for PowerPair eligibility. An installer who is not on Duke’s list cannot file the rebate paperwork.
- What is your current interconnection lead time with Duke or Dominion? If you need to lock the Bridge before December 31, 2026, the interconnection date is what counts, not the installation date.
- Will the system carry PE-stamped structural plans? Required for coastal wind zones at 140+ mph, multi-layer roofs, and any installation that adds more than 3 psf.
- How are you sizing the battery for Solar Choice TOU? If Solar Choice is your only option, battery sizing drives the payback.

Frequently Asked Questions
A residential solar system in North Carolina runs $2.61 per watt installed in the competitive market, which puts most 8 kW systems in the $18,400 to $23,400 range before incentives. 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.
No, not for a cash or loan purchase. Section 25D ended for systems placed in service 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.
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.
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.
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. Payback runs 10 to 13 years even without the federal credit, with two decades of effectively free electricity after that.
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.
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.
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.
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.
