Wilmington solar works well because the Cape Fear coast gets strong sun, but its defining issue is wind. New Hanover County sits in a 140 mph design-wind zone (150 mph on the barrier islands), so racking and roof attachment must be engineered to code. Homes here are served by Duke Energy Progress, and North Carolina power runs about 15.09 cents per kWh.
Wilmington is a strong rooftop solar market with one coastal twist that inland cities like Raleigh and Charlotte do not face: engineering for hurricanes and salt air. The Cape Fear coast gets plenty of sun and North Carolina’s power prices sit below the national average, so the production case is real. What makes a Wilmington system different is how it is anchored to your roof and how it holds up to marine air. Wilmington homes sit in Duke Energy Progress territory, which retired full-retail net metering for new solar in 2023, and the federal homeowner tax credit ended after 2025. This page covers what solar costs in Wilmington in 2026, the coastal wind-load engineering that matters here, how Duke Energy Progress credits your exports, and which incentives are still live. Every figure is dated and linked to its source. For the statewide picture, start with our North Carolina solar guide. Updated for 2026.
What solar costs in Wilmington in 2026
North Carolina’s power prices sit below the national average, which is the honest starting point. At about 15.09 cents per kWh for residential customers (EIA Electric Power Monthly, Table 5.6.A, data for May 2026; national average about 18.4 cents), the bill that solar offsets in Wilmington is smaller than in the high-rate Northeast. What tips the math in Wilmington’s favor is coastal sunshine, so a right-sized system produces a lot of kilowatt-hours per dollar of panel.
According to MySolarFY’s analysis (August 2026), a typical 6 kW system in Wilmington (ZIP 28401) produces about 8,224 kWh a year (modeled with NREL’s PVWatts calculator, v8, standard assumptions). That works out to roughly 1,371 kWh per installed kW each year, a strong specific yield, which at North Carolina’s current 15.09 cents per kWh trims about $103 off a typical monthly power bill (about $1,241 a year). Your own output depends on roof pitch, orientation, and shade from live oaks and coastal trees, so treat this as a planning estimate and run your own address through PVWatts for a tighter number. For the full cost-per-watt and payback breakdown, see our North Carolina solar cost and payback guide.
Coastal wind-load engineering: the thing Wilmington solar gets right or wrong
This is the part statewide guides skip. Wilmington sits on the hurricane coast, and the North Carolina Residential Code sets a much higher design-wind standard here than in the Piedmont. New Hanover County falls in a 140 mph ultimate design-wind zone west of US-17, rising to 150 mph east of US-17 and on the barrier islands at Wrightsville Beach, Carolina Beach, and Kure Beach, where oceanfront Exposure C applies (North Carolina Residential Code, high-wind provisions; design speeds follow the ASCE 7 wind maps the code adopts). A solar array is a wind-loaded surface, so on the coast the attachment and racking are engineered, not standard.
| Where the home is | Design wind speed (3-second gust) | What it means for a solar mount |
|---|---|---|
| Inland Wilmington, west of US-17 | About 140 mph | Tighter attachment spacing and structural review of the roof framing; a signed engineering document is typical |
| East of US-17 and the barrier islands | About 150 mph, oceanfront Exposure C | Highest uplift loads; more attachment points, upgraded flashing, and often a stamped structural calculation |
| Source | North Carolina Residential Code, high-wind zones; confirm the exact wind speed and exposure category for your address with your installer’s engineer | |
What to ask a Wilmington installer about wind: confirm the racking system’s rated design-wind speed meets or beats your address’s requirement, that the roof-to-frame load path was reviewed, and that the permit package includes the structural document New Hanover County or the City of Wilmington expects. A well-engineered coastal array is designed to ride out named storms; the failures you read about are usually undersized attachment, not the panels themselves.
Salt air and durability on the Cape Fear coast
Wilmington’s second coastal factor is marine air. Salt-laden humidity accelerates corrosion on exposed metal, so component selection matters more here than inland. Reputable coastal installs lean on aluminum rails, stainless-steel fasteners, and connectors rated for the environment, and most solar panels and racking carry manufacturer testing for salt-mist and humidity. This is worth confirming in writing rather than assuming, especially within a few miles of the water. Ask your installer which racking and hardware they use near the coast, what the salt-corrosion and workmanship warranties cover, and how flashing is detailed to keep a coastal roof watertight. None of this makes coastal solar impractical; it just means the quality of the hardware and the install crew carries more weight in Wilmington than in a dry inland market.
Net metering in Wilmington: the Duke Energy Progress riders
The big change: full-retail 1:1 net metering is gone for new solar customers. Duke Energy’s legacy Rider NM, which credited every exported kilowatt-hour at the full retail rate, closed to new residential solar on September 30, 2023 (DSIRE, North Carolina net metering). Because Wilmington is served by Duke Energy Progress, new customers now choose between two Duke riders, and the one you pick decides what your exports are worth. Verify the current terms and any capacity limits with Duke before you sign.
| Duke rider (new Wilmington solar) | How it credits you | The catch to verify |
|---|---|---|
| Rider NMB (Net Metering Bridge) | Simple monthly netting, no time-of-use requirement, a set stay period | A transitional option that is capacity-capped and time-limited, so confirm it is still open on Duke Energy Progress |
| Rider RSC (Residential Solar Choice) | Time-of-use pricing with critical peak periods; exports credited near Duke’s avoided-cost rate, not full retail | Adds a minimum monthly bill and non-bypassable charges, so shifting usage to off-peak matters |
| Source | DSIRE, North Carolina net metering; confirm current tariff terms with Duke Energy | |
What this means for a Wilmington homeowner: the bridge rate (Rider NMB) is the friendlier option because it keeps simple monthly netting, while Residential Solar Choice (Rider RSC) shifts you to time-of-use and credits exports below retail. Reporting on the settlement puts the Duke Energy Progress minimum monthly bill near $28 and any surplus export credit in the low single-digit cents per kWh, well under retail (EnergySage, as of August 2026), so verify the current figure with Duke. Because the bridge rider is capacity-limited and time-bound, its availability is exactly the kind of thing to verify before you commit. Either way, sizing a system to your own usage matters more than it used to, since over-exporting no longer earns full retail. To see how the credit works in detail, read how net metering credits your solar exports, and for how the bridge rate and time-of-use exports compare across Duke’s operating companies, see our North Carolina net metering guide for 2026. For the full Duke breakdown, including interconnection and the PowerPair battery rebate, see our Duke Energy North Carolina solar guide.
Wilmington solar incentives in 2026 (including Duke PowerPair)
North Carolina does not run an SREC market or a state income-tax credit, so a Wilmington incentive stack is shorter than Maryland’s or New Jersey’s. What it does have is a strong property-tax exemption and a Duke solar-plus-battery rebate. Here is what is live in 2026, with the detail that is specific to Wilmington’s utility.
| Incentive | What it pays | 2026 status for Wilmington to verify |
|---|---|---|
| Duke PowerPair (solar + battery) | A one-time incentive of up to $9,000 for pairing home solar with a battery | Wilmington is on Duke Energy Progress, and the Duke Energy Progress side of this capped pilot filled its cap in late 2025 and moved new applicants to a waitlist. Confirm current Duke Energy Progress availability before counting on it |
| Property-tax exemption | Excludes 80% of a residential solar system’s value from property tax | A standing North Carolina law; your added home value in New Hanover County is largely shielded from higher property taxes |
| State income-tax credit | None for homeowners | North Carolina’s old 35% credit expired for systems placed in service after December 31, 2015; there is no current state credit |
| Federal residential (Section 25D) | A 30% homeowner credit | Ended for expenditures made after December 31, 2025; a 2026 buyer cannot claim it |
The property-tax exemption is the durable one. North Carolina excludes 80% of a residential solar electric system’s value from your property-tax assessment, so adding panels does not swing your New Hanover County tax bill the way a home addition would (DSIRE, North Carolina property-tax abatement). Duke’s PowerPair pilot pays a one-time incentive of up to $9,000 to homeowners who pair solar with a battery (Duke Energy, announced April 2024), but it is a capped pilot split by operating company, and the Duke Energy Progress territory that serves Wilmington reached its cap in late 2025 and began waitlisting, so confirm current availability before you count on it. For a full breakdown of every North Carolina incentive, see our North Carolina solar incentives 2026 guide.
Heads up on the federal credit: the 30% federal Residential Clean Energy Credit (Section 25D) ended for expenditures made after December 31, 2025, so a Wilmington homeowner buying with cash or a loan in 2026 cannot claim it (IRS). A separate commercial credit (Section 48E) can apply to leased and PPA systems, but the company that owns the panels claims it, not you. Always confirm your own situation with a licensed tax professional. MySolarFY does not provide tax advice.

A lease or PPA can carry an annual price escalator and, over its full term, may cost more than owning the system with cash or a loan. On a lease or PPA the provider owns the panels and keeps any tax benefits, and the 30% federal credit ended after December 31, 2025. Not a savings guarantee.
Permitting solar in Wilmington and New Hanover County
Where your Wilmington home sits decides who permits it: addresses inside the city go through the City of Wilmington, while unincorporated areas go through New Hanover County. On the coast, the permit review is not just electrical; because of the high design-wind loads, the structural attachment gets real scrutiny. Your installer normally pulls the permit and files the Duke Energy Progress interconnection application, and a signed and sealed structural document is commonly required given the wind zone. New Hanover County reviews residential solar as both a building and an electrical scope and its guidance calls for a structural load analysis stamped by a North Carolina licensed professional engineer, an electrical one-line diagram, manufacturer cut sheets, and a Duke Energy interconnection application (New Hanover County Solar Energy).
A few Wilmington and New Hanover County specifics worth knowing before you sign:
- Who files it: a licensed installer normally handles the local permit and the Duke Energy Progress interconnection application. Confirm both are in your contract.
- Wind engineering: ask that the permit package documents the racking’s rated wind speed and the roof-to-frame load path for your specific 140 mph or 150 mph zone.
- Flood and coastal overlays: homes in flood-hazard or oceanfront zones can carry added requirements, so have your installer check before scheduling.
- Inspection and interconnection: inspection follows permit issuance, and Duke Energy Progress interconnection is a separate step from the local building permit.
Because rules can change, verify current requirements with the City of Wilmington or New Hanover County permitting office for your address, and confirm interconnection steps with Duke. To pressure-test any installer’s numbers, use the right questions to ask a solar installer.
Is solar worth it in Wilmington?
For many Wilmington homeowners, yes, but the coastal case rests on production, quality engineering, and the property-tax break more than on a rich incentive stack. With below-average power prices, the payback here is driven by strong Cape Fear sun, a system sized to your own use under Duke Energy Progress’s newer riders, corrosion-resistant hardware that survives salt air, and keeping your added home value out of your New Hanover County property-tax bill. If you own the system through cash or a loan, you keep those benefits directly; if you lease or sign a PPA, the company that owns the panels keeps any tax benefits while you get a lower or fixed power price with no up-front cost. For a full payback walkthrough, see the financial case for whether solar panels are worth it, and for the broader picture, browse our solar by state guides.
Paying for solar in Wilmington: cash, loan, lease, or PPA
There is no single right way to pay for solar in Wilmington. The best fit depends on whether you want to own the system and how you feel about an up-front cost. A lease or PPA can mean no up-front cost for eligible homeowners, but it is a long-term agreement with monthly payments, not free solar, and the company that owns the panels keeps any credits or benefits that go to the system owner.
| Path | Up-front cost | Who owns the system | Best when |
|---|---|---|---|
| Cash purchase | Full system cost | You | You want the fastest payback and the most lifetime savings |
| Solar loan | Little to none, financed | You | You want ownership without paying cash up front |
| Lease or PPA | No up-front cost where eligible | The third-party owner | You prefer no up-front cost and a simpler, fixed monthly bill |
How to choose a Wilmington installer: screen any company against objective criteria rather than a “best” list. Look for NABCEP certification, a valid North Carolina electrical license, documented coastal wind-load engineering, a written workmanship and equipment warranty, real local experience with New Hanover County or City of Wilmington permitting and Duke Energy Progress interconnection, and a clear production estimate you can compare. For how the same utility and incentives play out in the state’s larger inland markets, compare our Raleigh solar guide and Charlotte solar guide. MySolarFY matches you with licensed installers that serve the Wilmington area so you can compare real local quotes side by side, with no obligation. Keep in mind the 30% federal Residential Clean Energy Credit ended for expenditures made after December 31, 2025, so a 2026 cash or loan buyer cannot claim it; for the full timeline, read what the federal solar tax credit change means for homeowners.
Frequently asked questions
Which utility serves Wilmington for solar? Wilmington is in Duke Energy Progress territory, one of Duke Energy’s two North Carolina operating companies. That matters because your net-metering rider and your PowerPair eligibility follow Duke Energy Progress specifically, and they differ from the Duke Energy Carolinas rules that cover Charlotte and the Piedmont. If your address is served by a cooperative or a city utility instead, your terms will differ, so confirm your provider before planning.
Do Wilmington homes need special engineering for hurricanes? Yes. New Hanover County sits in a high-wind coastal zone, roughly a 140 mph ultimate design-wind speed west of US-17 and about 150 mph east of US-17 and on the barrier islands, where oceanfront Exposure C applies. A solar array is a wind-loaded surface, so the racking must be rated for your address’s wind speed and the roof-to-frame load path reviewed. Ask your installer to document this in the permit package. Well-engineered coastal arrays are designed to withstand named storms.
Does salt air damage solar panels in Wilmington? Salt-laden coastal air accelerates corrosion on exposed metal, so hardware choice matters more here than inland. Reputable coastal installs use aluminum rails, stainless-steel fasteners, and connectors rated for the marine environment, and most panels and racking carry salt-mist and humidity testing. Ask your installer which racking they use near the coast and what the corrosion and workmanship warranties cover. Coastal solar is practical; the quality of the hardware just carries more weight.
Is net metering still available in Wilmington? Yes, but not the old full-retail version for new customers. Duke Energy’s legacy 1:1 net metering (Rider NM) closed to new residential solar on September 30, 2023. New Wilmington customers on Duke Energy Progress choose between Rider NMB, a transitional bridge option with simple monthly netting, and Rider RSC (Residential Solar Choice), a time-of-use rate that credits exports near Duke’s avoided-cost rate rather than full retail and adds a minimum monthly bill. Because the bridge option is capacity-capped, verify current availability with Duke.
How much does solar produce in Wilmington? Production depends on your roof, but as a benchmark MySolarFY’s analysis (August 2026) models a typical 6 kW system at ZIP 28401 at about 8,224 kWh a year using NREL’s PVWatts calculator, roughly 1,371 kWh per installed kW. At North Carolina’s current 15.09 cents per kWh that offsets about $103 off a typical monthly bill, near $1,241 a year. Roof pitch, orientation, and coastal tree shade all move that number, so run your own address through PVWatts for a tighter estimate.
Does Wilmington or North Carolina have a state solar tax credit? No. North Carolina’s 35% state solar tax credit expired for systems placed in service after December 31, 2015, and there is no general residential state solar income-tax credit today. The durable tax benefit for a Wilmington homeowner is the property-tax exemption, which excludes 80% of the system’s value from your New Hanover County property-tax assessment. The federal Residential Clean Energy Credit (Section 25D) separately ended after December 31, 2025.
Reviewed by the MySolarFY team. Figures were verified against the linked EIA (North Carolina residential rate), NREL PVWatts (Wilmington ZIP 28401 production estimate), New Hanover County, DSIRE net-metering, and IRS sources as of August 2026. Duke Energy Progress net-metering riders, the minimum monthly bill and export credit, PowerPair availability, and coastal permitting details can change, so confirm current terms with Duke Energy Progress and your local permitting office before you decide.
