North Carolina doesn't always get the attention it deserves in the residential solar conversation. But with over 8,000 megawatts of installed solar capacity — enough to generate nearly 10% of the state's electricity — the Tar Heel State ranks among the top four in the country by total installed capacity. That's not an accident. It reflects real financial incentives, good solar resources, and a policy environment that has historically supported residential adoption.
That environment is shifting in 2026. The federal tax credit is gone. Duke Energy's net metering structure has fundamentally changed. And two major program deadlines fall at the end of this year. For homeowners trying to understand whether solar still makes sense, the picture requires more nuance than it did a few years ago — but the answer is often still yes, with the right system design and the right timing.

The Federal Tax Credit: What Happened
The story is the same as in every other state: the federal residential solar tax credit (Section 25D) expired on December 31, 2025. The One Big Beautiful Bill Act, signed July 4, 2025, ended the 30% credit for homeowners purchasing or financing a solar system. Systems fully installed by that date can still claim it when filing 2025 taxes, and unused credit from prior years can carry forward — but new purchased installations in 2026 do not qualify.
The one remaining federal pathway is third-party ownership — solar leases and Power Purchase Agreements (PPAs). Because the financing company owns the system, it can claim the commercial Investment Tax Credit (Section 48E) and pass some of that savings through via lower monthly payments. That credit is available through the end of 2027.
There is no state solar income tax credit in North Carolina. There hasn't been one for years, and none is currently on the legislative horizon. If you see it listed on a proposal, ask for the citation — it doesn't exist.
North Carolina Incentives: A Utility-Driven Stack
What North Carolina does have is a meaningful set of utility programs, tax exemptions, and a critical rate election that closes at the end of this year. The incentive picture varies significantly depending on which utility serves your home — Duke Energy Carolinas, Duke Energy Progress, and Dominion Energy customers all have meaningfully different options.
Net Metering and Rate Structure: The Most Important Decision You'll Make
This is where North Carolina diverges sharply from states with simpler solar economics, and it's the single most important factor in how your solar investment performs.
Dominion Energy customers (northeastern North Carolina) have the most straightforward situation: traditional 1:1 net metering, meaning excess solar generation earns retail-rate credits that offset future bills at full value. This is the structure that makes solar economics cleanest, and it's one reason to feel good about going solar if Dominion is your utility.
Duke Energy customers — which covers most of the state — face a more complicated picture. Duke changed its net metering rules in 2023. New customers who interconnect after October 1, 2023, are placed on one of two rate options:
The Net Metering Bridge Rate (Rider NMB) is the better of the two available options for new Duke solar customers. It protects you from time-of-use rate structures and still compensates excess energy at a reasonable rate. The critical detail: the Bridge Rate is only available through December 31, 2026, and once you're enrolled, Duke locks in your eligibility for 15 years. After that deadline, the Bridge Rate closes permanently to new applicants.
The Residential Solar Choice Rate (Rider RSC) is the default plan for Duke customers who don't elect the Bridge Rate — or who interconnect after the Bridge Rate closes. It's a time-of-use structure with export credits paid at Duke's Net Excess Energy Credit rate of approximately $0.034 per kWh — roughly 75–80% below the retail electricity rate. Your panels produce the most power in the middle of the day, when Duke considers that off-peak and values it lowest. You then buy power in the evening at higher on-peak rates. The math is considerably less favorable than full retail net metering.
For Duke customers, the practical implication is clear: if you're going to go solar, doing it before December 31, 2026, and locking into the Bridge Rate is materially better than waiting. Getting your interconnection request filed and approved takes time — planning to sign a contract in December is too late. Late summer or early fall is the realistic window to secure a spot.
Rural electric cooperative customers are in a different situation. Most co-ops in North Carolina use net billing at avoided-cost rates of roughly 3–4¢ per kWh for exported power — similar to Duke's default rate. Blue Ridge EMC is a notable exception, offering customers a choice between retail net metering and net billing. If you're served by a cooperative, contact them directly for current terms before assuming any rate structure applies.
Duke Energy PowerPair
For Duke Energy customers, PowerPair is the most significant solar incentive currently on the table. The program provides a one-time upfront rebate for customers who install solar and battery storage together:
- $360 per watt-AC for solar panels, up to 10 kW (maximum solar rebate: $3,600)
- $400 per kWh for battery storage, up to 13.5 kWh (maximum battery rebate: $5,400)
- Combined maximum: $9,000 for a paired solar-plus-storage system
A 7 kW solar system paired with a 13.5 kWh Tesla Powerwall would earn approximately $7,920 in PowerPair incentives. A 10 kW system with the same battery hits the maximum $9,000.
Availability is the catch. Duke Energy Progress has largely exhausted its initial PowerPair allocation and is operating on a waitlist. Duke Energy Carolinas still has remaining capacity as of spring 2026, but is approaching limits. This is genuinely a first-come, first-served situation, and the program is not guaranteed to reload with new funding. If you're in Duke territory and PowerPair is part of your financial plan, acting sooner matters.
Note that PowerPair requires battery storage — solar-only installations are not eligible. This has effectively shifted the calculus for many Duke customers toward solar-plus-storage systems even when backup power alone wouldn't have justified the added cost.
Duke Energy Battery Programs
Beyond PowerPair, Duke offers ongoing incentive programs for battery owners that can add meaningful value over time.
Power Manager (Duke Energy Carolinas) / Energy Wise (Duke Energy Progress): These demand-response programs pay battery owners for allowing Duke to dispatch stored power during peak grid demand events. Enrollment provides ongoing bill credits in exchange for controlled battery discharges during designated events — similar in concept to Colorado's Renewable Battery Connect program. The specific credit amounts vary based on battery size and dispatch frequency. Enrollment also affects your net metering rate options, so it's worth discussing the full picture with an installer before committing.
EnergyWise Home Battery Program: A virtual power plant program in which Duke aggregates battery storage across enrolled homes to manage peak grid demand. Battery owners retain a protected minimum reserve, and Duke can discharge the battery up to a set number of times annually. This is the program required to access the Solar Bridge Rate for battery customers, which creates a meaningful incentive for enrollment.
Property Tax Exemption
North Carolina law provides a 100% property tax exemption for residential solar systems. Under NCGS § 105-275(45), the value a solar installation adds to your home is classified as non-business personal property and excluded entirely from your property tax assessment.
Solar systems typically add 4–7% to a home's value in North Carolina. On a $350,000 home, a 5% increase would represent $17,500 in added value. At North Carolina's effective residential property tax rate — which varies by county but averages roughly 0.7–0.9% — that's $122–$157 per year in taxes you're not paying. Over a 25-year panel lifespan, the cumulative savings run $3,000–$4,000 or more, higher in urban counties with elevated mill levies.
Important note: Legislative proposals in 2025 raised the possibility of modifying the property tax exemption structure beginning July 1, 2026. The current full exemption has not been eliminated as of this writing, but this is worth verifying with your county tax assessor or a tax professional before installation.
No application is required for residential systems — the exemption is automatic.
Sales Tax Exemption
North Carolina exempts solar energy equipment from the state sales and use tax. Panels, inverters, racking, and associated system components are all covered.
North Carolina's state sales tax rate is 4.75%, with local add-ons bringing the combined rate to 6.75–7.5% in most counties. On a $25,000 solar installation, the exemption represents roughly $1,700–$1,875 in avoided taxes — and it applies at the point of sale, so you simply don't pay it. This is one of the more substantial sales tax exemptions among southeastern states.
HOA Protections
Worth mentioning for homeowners in planned communities: North Carolina law (NCGS § 22B-20) prohibits HOAs from banning solar panel installations outright. HOAs may impose reasonable restrictions on placement, but they cannot require decisions that significantly increase system cost or reduce production by more than 10%. If your HOA objects to your installation, that's a legal matter worth discussing with a North Carolina attorney — but the baseline right to install solar is protected by statute.
Battery Storage Incentives
The case for pairing battery storage with solar is stronger in North Carolina than in most states, for a reason specific to Duke Energy's rate structure: because exported solar power earns only about 3–4¢ per kWh under the default Duke rate plan, every kilowatt-hour you can store and self-consume instead of exporting is worth roughly 10–11¢ more. The financial penalty for oversizing a system without storage is significant. A battery that captures midday solar production for evening use closes that gap considerably.
The available incentives make the math more manageable:
Duke PowerPair battery rebate: Up to $5,400 for battery storage as part of a combined solar-plus-storage installation, as described above.
Tesla Powerwall 3 rebate: Tesla is offering a $500 direct rebate for Powerwall installations contracted before June 30, 2026. This comes directly from Tesla and stacks with utility programs.
Duke Power Manager / Energy Wise credits: Ongoing bill credits for demand-response enrollment in Duke's battery programs. The specific credit amount depends on battery size and dispatch frequency but represents meaningful annual value over the life of the system.
Stacking the PowerPair battery rebate, Tesla's direct incentive, and the ongoing demand-response credits can reduce battery system costs by 35–50% for qualifying Duke Energy customers — making solar-plus-storage more financially comparable to solar-only than it would be in most markets.
What's the ROI Picture in 2026?
North Carolina's solar economics require honesty about two factors that work against simple payback calculations: below-average electricity rates and a net metering structure (for Duke customers) that doesn't fully compensate exported power.
Electricity rates in North Carolina average approximately $0.14 per kWh for Duke Energy residential customers as of early 2026 — roughly 26% below the national average. That's lower than Colorado, lower than most of the Mid-Atlantic and Northeast, and considerably lower than the high-rate states where solar ROI math is simplest. Every kilowatt-hour your solar system produces saves you 14¢, not 25¢ or 30¢ like in New England. Same sun — less savings per panel.
Rate trajectory matters, though, and here North Carolina has a clear trend. Residential rates climbed from 11.3¢ per kWh in 2021 to roughly 14¢ by early 2026 — a 24% increase in under five years. Duke Energy has filed for additional rate increases, and the regulatory environment doesn't suggest that trajectory is ending. Every rate increase makes your existing solar system more valuable, because the electricity your panels produce offsets whatever Duke charges at the time — not what they charged when you installed.
The payback picture in 2026, without the federal tax credit:
For Dominion Energy customers with traditional 1:1 net metering, payback periods for cash purchases typically run 9–11 years at current rates, shortening to 8–10 years with a modest annual rate escalation assumption. Twenty-five-year net savings for a well-sized system in Dominion territory run in the range of $30,000–$45,000.
For Duke Energy customers on the Bridge Rate, payback periods run approximately 10–13 years without the federal credit, depending on system size and electricity usage. That stretches compared to prior years, but the long-term case remains solid for homeowners planning to stay in their home. The key variable is locking into the Bridge Rate before year end.
For Duke Energy customers on the default Solar Choice rate, the math is more difficult. Exporting excess solar power at 3–4¢ per kWh while buying evening power at 12–14¢ meaningfully extends payback periods and reduces the value of oversized systems. For these customers, system sizing and storage become more important than ever — designing for high self-consumption rather than maximum production.
A realistic example: A Duke Energy Carolinas customer in Charlotte installs an 8 kW system paired with a 13.5 kWh battery. Gross system cost of roughly $37,000. After the PowerPair rebate ($9,000) and the Tesla rebate ($500), net cost is approximately $27,500. At current Duke rates with 80% self-consumption (thanks to the battery), annual electricity bill savings of approximately $1,800–$2,200 yield a payback of 12–15 years — declining toward 10–12 years with continued rate escalation. It's not the fastest payback in the country, but over 25 years, net savings in the range of $20,000–$35,000 represent a real return on a home improvement that also adds resale value.
Is Solar Still Worth It in North Carolina?
For Dominion Energy customers: the incentive picture is relatively clean, and the financial case is solid.
For Duke Energy customers: the answer depends heavily on which rate you lock into and whether you can still access the Bridge Rate and PowerPair. Both of those close or fill up by the end of 2026. A solar-plus-storage system designed around self-consumption, installed before December 31, makes considerably more sense than a solar-only system installed after the Bridge Rate expires.
For all North Carolina homeowners: system sizing matters more here than in states with full retail net metering. A system designed to match your actual annual consumption — not to maximize panel count — will outperform an oversized system that exports at a steep discount. Working with an installer who understands Duke's rate structure and designs for self-consumption rather than raw output is essential.
North Carolina's combination of property and sales tax exemptions, utility rebate programs, and — for the right customers — the Bridge Rate and PowerPair incentives still builds a real financial case. The deadline pressure is genuine, not just a sales tactic: two significant program benefits close permanently at the end of this year.
