Solar Panels in North Carolina: Duke Energy's Two Territories and What Each Pays

Q: "How much do solar panels cost in North Carolina in 2026?"

"As of March 2026, the average installed cost is approximately $2.34 per watt. A typical 13.77 kW system costs around $32,000 before incentives, while a smaller 5 kW setup runs about $11,700. Prices vary by installer, panel brand, and roof complexity. Getting at least three quotes is the most reliable way to find a competitive price for your specific home and electricity usage needs."

Q: "Is the federal solar tax credit still available in North Carolina?"

"No. The Residential Clean Energy Credit — which provided a 30% federal tax credit on solar installation costs — was eliminated effective January 1, 2026. Homeowners who completed installations by December 31, 2025 could still claim the credit on their 2025 tax return. New 2026 installations are not eligible. Homeowners signing a solar lease or PPA may benefit indirectly if the installer passes savings through lower contracted rates."

Q: "What is Duke Energy's PowerPair program and how does it work?"

"Duke Energy's PowerPair rebate offers up to $9,000 for North Carolina homeowners who install a solar-plus-battery system. It pays $0.36 per watt-AC for solar panels (maximum $3,600) and $400 per kWh of battery storage (maximum $5,400). The program carries a 30 MW capacity cap per Duke territory and operates first-come, first-served. Available capacity has been declining, so early application is advisable for eligible Duke customers."

Q: "Does North Carolina have net metering for solar customers?"

"Net metering depends on your utility. Dominion Energy customers receive full retail-rate net metering at approximately 14¢ per kWh for exported power. Duke Energy ended traditional net metering for new customers in October 2023 — new installs must choose the Net Metering Bridge Rate or the Residential Solar Choice time-of-use plan. Most electric cooperatives use net billing at avoided-cost rates of 3–4¢ per kWh, making self-consumption a financial priority."

Q: "How long does it take for solar panels to pay back in North Carolina?"

"Payback periods currently range from about 9 to 13 years for most residential installations without the federal tax credit. The range depends on your utility's net metering policy, system size, electricity usage, and financing method. Dominion Energy customers with good sun exposure typically break even faster than Duke Energy customers on time-of-use rates. Most systems carry a 25-year panel warranty, leaving over a decade of essentially free electricity after reaching payback."

Sizing formula kW = Annual kWh ÷ (Peak Sun Hours × 365 × 0.82)

North Carolina ranks among the top four states in the US for installed solar capacity, with over 8,000 megawatts of solar power generating nearly 10% of the state’s electricity, according to the Solar Energy Industries Association (SEIA). For homeowners, that translates into a mature market with competitive installation prices, strong utility rebate programs, and decades of policy infrastructure designed to make rooftop solar financially sensible. If you’ve been watching your Duke Energy or Dominion Energy bill climb — residential electricity rates in North Carolina rose from 11.3¢ per kWh in 2021 to roughly 14¢ per kWh by early 2026, a jump of approximately 24% in under five years — now is a reasonable time to understand exactly what solar costs and what it would save.

The financial picture has shifted meaningfully in 2026. The federal Residential Clean Energy Credit, which provided a 30% tax credit on the full cost of a solar installation, was eliminated effective January 1, 2026, after legislation signed in mid-2025. That changes the math considerably for homeowners who missed the deadline. The good news is that Duke Energy’s PowerPair rebate program, North Carolina’s permanent property tax exemption for solar, and Dominion Energy’s retail-rate net metering policy remain active and can still reduce upfront costs by thousands of dollars.

This guide covers what a system costs today, what incentives you can still claim in 2026, how net metering works with your specific utility, and how long it typically takes to recover the investment. The numbers vary meaningfully depending on your system size, utility provider, and financing method, so each scenario is covered in enough detail to support a confident decision.

What Solar Panels Cost in North Carolina in 2026

As of March 2026, the average installed cost of a solar panel system in North Carolina is approximately $2.34 per watt, based on real quote data from the EnergySage marketplace. For a 13.77 kW system — the typical size needed to cover the average North Carolina household’s electricity consumption — that works out to roughly $32,000 before any incentives. Prices range from around $27,400 on the low end to $37,000 for larger or more complex installations.

Smaller systems are proportionally cheaper. A 5 kW system runs approximately $11,700, while a 10 kW setup lands around $23,400. North Carolina averages about 5.2 peak sun hours per day, which is a solid solar resource compared to most of the country and means a properly sized system can offset the majority of a typical household’s annual electricity use.

The federal tax credit that used to reduce these costs by 30% is no longer available for residential systems installed in 2026. On a $32,000 system, that’s a $9,600 incentive that buyers a year ago could claim and new buyers cannot. This is the single biggest change to the North Carolina solar market in 2026, and it meaningfully extends the payback period for homeowners paying cash or financing with a loan.

Homeowners who sign a solar lease or power purchase agreement (PPA) may still benefit from the credit indirectly, since the company owning the system can pass along some savings through lower contracted rates. Comparing multiple installer quotes remains one of the most reliable ways to reduce upfront cost. Industry data consistently shows that homeowners who receive three or more quotes pay meaningfully less per watt than those who accept the first offer. Panel brand, inverter type, and roof complexity all influence final pricing — a south-facing, single-story roof with no shading can come in 10–15% cheaper than a multi-plane roof requiring additional racking hardware.

According to NREL’s PVWatts tool, a 10 kW system in Charlotte produces an estimated 14,200 kWh per year, while the same system in Raleigh produces around 14,500 kWh. That difference in solar resource matters when calculating annual bill offsets and comparing quotes on a cost-per-kWh-produced basis rather than a cost-per-watt basis.

2026 Solar Incentives Still Available in North Carolina

With the federal tax credit gone, the incentive landscape looks different than it did 18 months ago, but it is far from empty. The most significant program still running for Duke Energy customers is the PowerPair rebate, which offers up to $9,000 for homeowners who install a solar-plus-battery system. The incentive breaks down as $0.36 per watt-AC for solar panels (up to 10 kW, maximum $3,600) and $400 per kilowatt-hour of battery storage (up to 13.5 kWh, maximum $5,400). Duke Energy customers who also enroll in the Power Manager Battery Control program — which grants Duke limited authority to manage the battery up to 36 times per year — receive additional monthly bill credits on top of the one-time rebate.

The PowerPair program has capacity limits: 30 megawatts in each Duke Energy territory (Carolinas and Progress), enough for roughly 6,000 homes total across both territories. It operates on a first-come, first-served basis, and a waitlist is available once capacity is reached.

North Carolina permanently exempts the added home value from solar panels from property tax calculations under NC General Statute 105-275(45). According to research cited by SEIA and state tax records, solar installations typically add $30,000–$35,000 to a home’s assessed value. At North Carolina’s average property tax rate of 0.7%, that translates to annual tax savings of roughly $210–$245 — a modest but guaranteed annual benefit that compounds over a 25-year system lifespan, accumulating $5,250–$6,125 in total tax savings over that period. For a full cost breakdown by state and system size, see our guide to How Much Do Solar Panels Cost in 2026? Complete US.

North Carolina does not offer a solar sales tax exemption, so buyers pay the state’s 4.75% sales tax on equipment and materials. On a $32,000 system, that adds roughly $1,520 to the total project cost — an often-overlooked line item when comparing quotes. To model the incentives that still apply to your specific project, the solar tax credit calculator can account for the PowerPair rebate and property tax savings alongside any utility-level programs your installer identifies.

If you’re comparing North Carolina’s incentive stack against neighboring states, Virginia still offers a sales tax exemption on solar equipment, and South Carolina recently expanded its own state tax credit program — making for a notable regional contrast when evaluating cross-border properties or investment decisions. The IRS confirmed in early 2026 guidance that no retroactive reinstatement of the residential credit is currently under consideration, making state and utility programs the primary levers for reducing solar costs this year.

How Net Metering Works in North Carolina

Net metering policy in North Carolina is genuinely complicated because it depends almost entirely on which utility supplies your electricity. The rules differ substantially between Duke Energy, Dominion Energy, and the state’s electric cooperatives, and getting this wrong can significantly affect your long-term savings projections.

Dominion Energy customers get the most favorable terms. Dominion offers traditional retail-rate net metering, meaning excess solar power sent to the grid earns credits at the same rate customers pay for electricity — currently around 14¢ per kWh. These credits roll forward month-to-month and offset future bills dollar for dollar. This is the most valuable net metering structure available anywhere in the state.

Duke Energy customers face a more complicated arrangement. Duke ended traditional net metering for new customers in October 2023. New solar owners in Duke territory must now choose between two rate structures: the Net Metering Bridge Rate, which offers somewhat better compensation for exported energy but is subject to annual capacity limits, or the Residential Solar Choice rate, a time-of-use structure with variable pricing that shifts the value of solar production depending on when power is generated. Duke also adds new fixed charges to solar customers’ bills that net metering credits cannot offset.

Electric cooperatives — which serve much of rural North Carolina — generally use net billing at avoided-cost rates of roughly 3–4¢ per kWh for exported power. That rate is significantly lower than the retail rate and reduces the financial value of excess solar generation substantially. Blue Ridge EMC is a notable exception, offering customers a choice between retail net metering and net billing. Homeowners served by cooperatives are typically better served by sizing their system to cover self-consumption rather than maximizing export.

The practical takeaway: a Dominion customer and a Duke customer installing identical 10 kW systems in the same county can expect meaningfully different annual savings — potentially $500–$800 per year or more over time. Always confirm your utility’s current policy with your installer before finalizing a purchase, and use the solar net metering calculator to model how each rate plan affects your annual bill offset before you commit.

How Long Does Solar Take to Pay Back in North Carolina?

Without the federal tax credit, residential solar payback periods in North Carolina have stretched compared to 2024. Based on current EnergySage market data, the average payback period is approximately 9–13 years depending on system size, financing method, utility provider, and electricity consumption. Dominion Energy customers with favorable net metering tend toward the shorter end; Duke Energy customers on the Residential Solar Choice time-of-use rate land closer to the longer end.

On a 13.77 kW cash purchase at $32,000 with no federal credit, a homeowner needs to save roughly $2,500–$3,200 per year in electricity costs to break even within 10–13 years. At current North Carolina electricity rates of 14¢ per kWh and an average monthly household usage of around 1,033 kWh per month (per EIA data), that’s achievable for homes with good roof conditions and Dominion-style net metering.

The 25-year savings picture remains compelling even with the longer payback. According to EIA rate trend data and EnergySage projections, homeowners who install today and avoid rising electricity costs could accumulate around $55,000 in bill savings over a system’s lifetime after accounting for the upfront installation cost — even without the federal credit. That assumes electricity rates continue rising at their recent pace of roughly 3–4% annually, which EIA’s short-term energy outlook supports.

Financing terms matter enormously. A homeowner who takes out a solar loan at 7% interest will pay significantly more over the loan term than someone purchasing outright, trimming long-term savings by $5,000–$10,000 depending on loan structure and term length. A 20-year loan at 7% on a $32,000 system adds approximately $26,500 in total interest payments, nearly doubling the effective cost of the system and pushing the breakeven timeline well past the 15-year mark for most households.

Nearby states offer useful benchmarks: Florida homeowners often see payback in 7–9 years due to higher solar output and a stronger retail net metering framework, while Tennessee has fewer state-level incentive programs and typically longer payback windows than North Carolina. To get a specific estimate using your actual bill and proposed system size, the solar payback calculator lets you plug in your financing terms and utility rate plan to model the full timeline.

Adding Battery Storage in North Carolina

Battery storage has become more financially relevant in North Carolina for reasons beyond simple backup power. Duke Energy’s net billing structure means solar power exported to the grid earns substantially less than the retail electricity rate — which creates a strong financial case for storing excess energy and self-consuming it later rather than exporting it at a fraction of its value.

A standard Tesla Powerwall 3 runs approximately $15,600 installed before incentives. Combined with a 7 kW solar system at roughly $21,000, the total project cost before Duke’s PowerPair rebate sits around $36,600. After the $9,000 PowerPair incentive — which covers both the solar panels and the battery in a single rebate structure — the net cost drops to roughly $27,600. Under the maximum rebate scenario, the battery component is effectively offset in full by the program, making storage far more accessible than it would be in states without a comparable utility incentive.

Battery storage also addresses North Carolina’s grid reliability challenges. According to EIA reliability data, North Carolina utility customers averaged just over four hours of power outages per year, with some eastern and coastal regions experiencing significantly more during hurricane and storm seasons. A properly sized battery keeps critical loads running — refrigerator, medical equipment, lighting — through most typical outages without relying on a gas generator. For coastal homeowners east of I-95, the backup value alone can justify a portion of the battery’s cost given the frequency and severity of seasonal weather events.

Battery prices have declined meaningfully over the past three years. In early 2023, installed battery storage in North Carolina averaged closer to $18,000–$20,000 for a single-unit system. The roughly 15–20% price reduction since then, combined with the PowerPair rebate, has made solar-plus-storage competitive in ways it simply wasn’t before 2024. Compared to Georgia to the south, where utility-level battery rebate programs are more limited, North Carolina’s PowerPair structure is one of the more generous incentives in the Southeast. And relative to New York, which runs a state battery incentive through the NY-Sun program, NC’s program offers larger per-project rebate amounts but carries the risk of capacity limits and no guaranteed renewal.

For Duke Energy customers specifically, acting before the 30 MW cap is reached in your territory is worth prioritizing. Use the solar payback calculator to model the full financial picture — including the PowerPair rebate, annual bill offsets, and 25-year savings projection — before requesting installer quotes.
