- The guide’s estimate for an average-size cash system is about $24,800; actual costs and savings depend on your home, system, and utility billing rules.
- Solar production shifts with the seasons, and utility export credits vary; compare purchase and lease terms, local incentives, and installer proposals before deciding.
Wilmington Electricity Prices
Electricity prices have climbed in recent years, making the cost of power an important part of the solar conversation in Wilmington.
North Carolina’s average electricity price rose from 11.3¢ per kilowatt-hour in 2021 to 14.1¢ in 2024. It remained below the national average, which increased from 13.7¢ to 16.5¢ over the same period.
These are statewide averages, not Wilmington-specific rates. A home solar system may let Wilmington households use less electricity from the grid, which can help limit how much changing utility prices affect their bills.
Over time, producing some electricity at home can offer more control over energy costs. The actual value depends on factors such as system size, household use, utility rates, and available billing arrangements.
Price of Energy: North Carolina vs National Average
Wilmington Area Utility Providers
In Wilmington, NC, Duke Energy is the utility shown in this comparison. Its 2023 electricity price was 14.2¢ per kilowatt-hour (kWh); 2024 utility data is not yet available.
That was 1.3¢ above North Carolina’s 2023 average of 12.90¢/kWh, but 1.8¢ below the 16.0¢ national average. These figures show relative prices, not what caused the differences.
For Wilmington households, solar can provide an alternative source of electricity and may reduce how much power is bought from Duke Energy. Its value depends on household use, system output, and utility rules.

North Carolina Solar Incentives
Wilmington homeowners may find state and utility programs that help offset solar costs. Review solar incentives in North Carolina.
Eligible Duke Energy customers may receive recurring bill credits for allowing battery management during grid events. North Carolina excludes 80% of a qualifying solar electric system’s appraised value from property taxes. Utility net-metering or export-credit terms vary.
Credit amounts, eligibility, and utility terms differ, so review the applicable program details when estimating how incentives may affect solar costs in Wilmington.
| Incentive | Type | Description | Source |
|---|---|---|---|
| Duke Energy Battery Control monthly bill credits | Battery Storage Bill Credit | Eligible Duke Energy customers who allow the utility to manage their home battery during grid events may receive a recurring bill credit whose amount depends on the program and battery. | Learn More |
| North Carolina solar-electric property-tax exclusion | Property Tax Exclusion | North Carolina excludes 80% of the appraised value of a qualifying solar energy electric system from the property-tax base. | Learn More |
| North Carolina utility net metering and export-credit tariffs | Net Metering / Net Billing | Eligible interconnected solar customers may reduce electricity bills through self-consumption and utility credits for excess electricity, with rates and tariff terms depending on the serving utility. | Learn More |
Duke Energy offers a battery-control option through its Power Manager or EnergyWise Home programs. Participants allow Duke to adjust battery operation during grid events and may receive a monthly bill credit; the credit is not a single statewide amount and depends on the applicable program, tariff, and battery characteristics.
Dispatch and opt-out terms apply. Duke’s program announcement describes dispatch events during the year, but customers should confirm current availability, credit amounts, and control requirements for their service territory and battery before enrolling. This bill credit is separate from PowerPair’s one-time solar-and-battery incentive.
State law excludes 80% of the appraised value of a qualifying solar energy electric system from local property taxation. This reduces the value included in the property-tax assessment; it is not a cash rebate or income-tax credit.
The statutory definition covers equipment used directly and exclusively to convert solar energy to electricity. NCDOR provides the AV-10 application for property-tax exemption or exclusion, which homeowners generally submit to their county assessor. The statute does not clearly resolve whether a standalone battery qualifies, so ask the county assessor how it will treat the battery and what filing deadlines apply.
Net metering and net-billing tariffs can provide bill value for electricity a customer’s solar system exports, but they are billing policies rather than upfront rebates. For Duke Energy Carolinas and Duke Energy Progress customers on newer residential tariffs, monthly excess exports are generally credited at the utility’s Net Excess Energy Credit rate, based on avoided cost rather than the full retail rate; minimum bills and other non-bypassable charges may still apply. Rider RSC requires a time-of-use rate with critical-peak pricing, while Rider NMB has limited annual availability. Existing legacy Rider NM customers may remain on it through December 31, 2026, before transition to NMB under the described terms.
Tariffs, export rates, fees, and interconnection requirements vary by utility. Electric cooperatives and municipal utilities set their own terms, so homeowners served by those utilities should ask directly about export compensation and system limits. Obtain utility interconnection approval before operating a grid-connected system.

How to Choose a Solar Installer in Wilmington
Verify the license
North Carolina requires an electrical-contractor license for residential solar photovoltaic installations, regardless of project value. Ask which licensed electrical contractor will be responsible for the work, and confirm the license with the North Carolina State Board of Examiners of Electrical Contractors (NCBEEC). The state law is available here. A separate general-contractor license may apply to qualifying general-construction work; the threshold is generally $40,000 or more, subject to exceptions and project scope.
Look for certified installers
Ask whether the people designing and installing your system hold current NABCEP credentials, and verify what credential each person has through NABCEP. Certification can offer another way to assess relevant training and qualifications, but it is not a substitute for the required North Carolina electrical-contractor license or a guarantee of installation quality. Ask what any manufacturer certification covers, which products it applies to, and whether it is current; manufacturer-specific credentials are distinct from state licensing.
Compare quotes the same way
Request written proposals with matching assumptions. Compare these details side by side:
- System size in kilowatts (kW) and total price per watt.
- Panel and inverter brands and models.
- Estimated electricity production in kilowatt-hours per year (kWh/year), and the assumptions behind the estimate.
- Warranty terms for panel product and performance, inverter, workmanship, and roof penetrations.
- Who handles permit applications, inspections, and utility interconnection.
- Total cost or monthly payment, plus any payment escalator and how it changes over time.
Compare the contract and warranty language, not just the headline price. For context, Palmetto reports a median installed system size of 9.2 kW and about 82 days from signing to installation; these are Palmetto figures, not a market-wide benchmark.
Permits, interconnection and your HOA
Local inspection departments handle building and electrical permit applications and inspections. The homeowner or installer must apply to the serving electric utility and receive its review and approval before connecting; requirements vary by system size and location. In the Wilmington area, confirm which utility serves your home. Local utilities include Duke Energy Carolinas, LLC; Duke Energy Progress – (NC); EnergyUnited Elec Member Corp; and Virginia Electric & Power Co. Ask the utility and installer who submits each application and tracks approval. North Carolina law voids certain restrictions that prohibit or effectively prohibit residential solar collectors, but allows reasonable location or screening rules that do not prevent reasonable use, with specified exceptions. It does not guarantee a right to put panels anywhere on a roof. Review applicable HOA rules and discuss the roof layout early. See N.C. Gen. Stat. § 22B-20.
Red flags
- Pressure to sign the same day, before you can review the contract or compare quotes.
- An unlicensed crew, or an out-of-state crew when the responsible North Carolina license holder is unclear.
- A vague production estimate without a stated annual kWh figure.
- A large upfront deposit without a clear written payment schedule and scope of work.
- Promises of federal homeowner tax credits for purchases in 2026; homeowner credits ended December 31, 2025.
Leasing Solar Panels
For Wilmington homeowners, Palmetto lists a solar lease as available for customers served by Duke Energy Progress; leases are also available in Duke Energy Carolinas territory. Your options depend on your address and utility. A power purchase agreement (PPA) is not listed as available in these service areas.
With a lease, you pay an agreed monthly amount for the solar system’s use. A PPA instead charges for each kilowatt-hour the panels produce, so payments can vary with seasonal output. Learn more about buying or leasing solar.
Leasing typically avoids the large upfront cost of paying cash, and the system provider handles maintenance, rather than leaving you to arrange and pay for repairs as the owner. Review LightReach lease details and confirm your utility and contract terms.
Go solar without the investment
With LightReach, there are no investment costs to recoup, loan payments to manage, or maintenance needs to take on. As soon as your panels are active, your solar savings are too!

Yes, but the rules depend on your electric utility. Most Wilmington residents are served by Duke Energy Progress. Its former 1-to-1 net metering plan closed to new customers on October 1, 2023.
New eligible customers may receive monthly credits for excess solar power under the Net Metering Bridge Rider; exports are credited at 3.4¢ per kWh. When its annual capacity is full, Residential Solar Choice applies. Check your bill or contact your utility to confirm your rate and eligibility.
Yes, owned solar panels may increase a Wilmington home’s value. Zillow found homes with solar sold for about 4.1% more on average. That figure is not a guaranteed increase for every Wilmington property.
The finding applies to purchased or owned systems, not leased or third-party-owned (TPO) panels. A lease may affect resale differently because a buyer may need to assume the lease agreement.
In Wilmington, a LightReach solar lease has no upfront cost and offers a low fixed monthly payment. The calculator above estimates $77–$135 per month, with $103 per month for a medium-size home.
As an alternative, a cash-purchased system is estimated at $19,211–$31,780 (about $24,802 for a medium-size home). The federal 30% tax credit is no longer available for residential cash purchases following the 2025 federal law change. See the calculator above for estimates by home size.
With LightReach, Palmetto owns the solar system and you pay a set monthly lease amount, with no upfront cost. One payment covers the panels, installation, monitoring, maintenance, and protection program, including a 90% Production Guarantee.
For a typical 8.92 kW system in Wilmington, the estimated lease payment is about $103 per month, based on North Carolina’s production ratio and a rate of $0.105/kWh. Savings can start right away if the lease payment is less than your current electricity bill; utility charges may still apply.
Yes, solar can make sense in Wilmington, NC. The area averages about 5.1 peak sun hours daily, and rooftop panels can reduce electricity bought from the grid. The value of a solar installation depends on roof condition, shade, household use, system cost, and Duke Energy’s export-credit rules.
LightReach, Palmetto’s solar lease program, removes the upfront cost barrier entirely: homeowners can go solar with no money down and start saving from day one.
Wilmington residents may qualify for recurring Duke Energy bill credits for letting the utility manage a home battery during grid events. North Carolina excludes 80% of a qualifying solar electric system’s appraised value from local property taxes; this is not a rebate.
Utility export credits can lower bills, but terms vary. Duke’s newer tariffs generally credit excess power at avoided-cost rates, not retail rates. The federal 30% residential credit is no longer available for cash purchases after 2025; Palmetto says LightReach leases retain commercial ITC savings, passed through in lease pricing.
In Wilmington, a 10 kW solar system is estimated to produce about 13,900 kilowatt-hours (kWh) per year, based on the article’s NREL PVWatts data. A more typical 8.92 kW home system would generate roughly 12,400 kWh annually.
Production is higher in sunnier months and lower in winter. Your actual output depends on roof direction and pitch, shade from trees or nearby buildings, weather, and seasonal daylight.
