Does North Carolina have a state solar tax credit?

No. North Carolina's 35% state tax credit for renewable energy investments expired at the end of 2015 and was never renewed. Homeowners installing solar today rely on the property tax exemption and net metering credits rather than any state income tax credit.

Does North Carolina still have net metering?

Yes, but Duke Energy has moved away from simple 1:1 kilowatt-hour crediting toward a structure built around time-of-use export rates and a minimum monthly bill for solar customers, approved by state regulators as part of a multi-year transition. The days of a flat retail-rate credit for every exported kilowatt-hour are ending in North Carolina, even though net metering itself hasn't gone away.

What solar tax exemptions does North Carolina offer?

North Carolina exempts 80% of the appraised value of a home solar energy system from local property tax assessment under state law (N.C.G.S. 105-275). That means only 20% of the added value from your solar installation gets factored into your property tax bill.

Is solar still worth it in North Carolina without the federal tax credit?

For systems placed in service in 2026 or later, the 30% federal residential clean energy credit ended December 31, 2025. Without a state credit either, North Carolina's payback math now rests almost entirely on the 80% property tax exemption, your specific Duke Energy rate plan, and how much of your own production you can use directly rather than export.

The bottom line first: North Carolina never had a generous solar tax credit to lose — the state's 35% credit expired back in 2015 — so the incentive picture here has looked different from neighboring states for almost a decade. What's changed more recently, and what actually matters for your 2026 math, is Duke Energy's shift away from simple kilowatt-hour-for-kilowatt-hour net metering toward a time-of-use export structure with a minimum monthly bill for solar customers. Combined with the federal tax credit ending for new systems, North Carolina homeowners now need to think harder about self-consumption and battery storage than the "install it and let the meter run backward" approach that worked a few years ago. This guide walks through what solar actually costs in North Carolina right now, what incentives remain, and why backup power deserves real attention in a state that gets hit by both hurricanes on the coast and ice storms and remnant tropical systems inland.

Why North Carolina's Incentive Picture Looks Thin on Paper

If you've read solar guides for states like South Carolina, New York, or California, you've seen the pattern: a state tax credit stacked on top of the old federal credit, plus some form of net metering. North Carolina doesn't fit that pattern, and hasn't for years.

No state income tax credit. North Carolina offered a 35% state tax credit for renewable energy investments, but it expired for systems placed in service after December 31, 2015, and the legislature hasn't reinstated it. If you're comparing North Carolina to a state that still advertises a state credit, that's the single biggest structural difference.

An 80% property tax exemption. This is the incentive that actually does the most work in North Carolina, and it's easy to miss because it's not a check you receive — it's a bill you never get. Under North Carolina law, 80% of the appraised value your solar system adds to your home is exempted from local property tax assessment. Only 20% of that added value gets taxed, which is a meaningfully better deal than states with no exemption at all, where a solar-driven jump in your home's assessed value comes with a matching jump in your annual property tax bill.

No sales tax exemption specific to residential solar equipment. Unlike Florida, North Carolina doesn't carve out a blanket sales tax exemption for solar panels and batteries at the point of purchase, so that cost is typically baked into your installer's quote rather than something you separately avoid.

No federal credit for new systems. The 30% federal residential clean energy credit (Section 25D) ended for systems placed in service after December 31, 2025. If you're installing in 2026, that credit isn't part of your math, though it's worth confirming with your installer whether your specific contract date affects eligibility.

Put together, North Carolina's remaining incentive stack is smaller than it looks at first glance, which makes getting your system sized correctly and your rate plan understood — rather than assuming a state credit will smooth over a mediocre quote — more important than in states with a thicker incentive layer to fall back on.

What Solar Actually Costs in North Carolina Right Now

North Carolina system pricing runs close to the national average, generally landing in the $2.60 to $3.20 per watt range before any incentives, which puts a typical 7 to 8 kW system — sized for a mid-size Piedmont or coastal-plain home — at roughly $19,000 to $26,000 before the property tax exemption factors into your long-term cost.

A few things shape North Carolina pricing specifically:

Regional variation is real. Installer density and competition are higher around Charlotte, the Triangle, and the Triad than in rural eastern or far-western counties, and pricing per watt tends to track that density. Getting quotes from installers who actually work your specific county matters more here than in smaller, more uniform states.
Roof age and type affect timeline more than cost. North Carolina's housing stock skews older in some markets than the Sun Belt states driving most solar growth, and installers routinely flag roofs that need replacement within 5 to 10 years as a reason to handle the roof first — not because it changes the panel cost, but because re-roofing around an installed array roughly doubles that labor bill later.
Duke Energy dominates, but isn't the only utility. Duke Energy Carolinas and Duke Energy Progress cover most of the state, but municipal utilities and electric cooperatives serve meaningful pockets of North Carolina with their own interconnection rules and rate structures that don't automatically match Duke's.

Because there's no state or federal credit left to apply, the number an installer quotes you is close to what you'll actually pay. That makes shopping multiple quotes more valuable in North Carolina than in a state where a big credit narrows the gap between a mediocre installer and a good one.

The Net Metering Shift Homeowners Need to Understand

This is the part of the North Carolina picture that's actually moving, and it's the detail that changes how you should size and use a system in 2026 versus a few years ago.

For years, Duke Energy's net metering credited exported solar at close to the full retail rate, kilowatt-hour for kilowatt-hour — the simple version most homeowners assume when they hear "net metering." Regulators approved changes that move Duke's residential solar customers toward a structure built around time-of-use export rates and a minimum monthly bill, rather than a flat retail-rate credit for every kilowatt-hour you send back to the grid.

What that means practically: the value of a kilowatt-hour you export at 1 p.m., when your panels are producing at peak and the grid often has plenty of solar already, is not the same as the value of a kilowatt-hour you use directly in your home instead of exporting it. Under a time-of-use structure, using more of your own production — running the dishwasher and doing laundry while the sun is up, charging an EV midday instead of overnight, or shifting load with a battery — captures more value than exporting and buying it back later ever will.

This is exactly the kind of rate change that makes battery storage a genuinely different financial decision than it was under old-style 1:1 net metering. A battery isn't just backup power in this environment — it's a way to store midday production you'd otherwise export at a lower credit and use it during evening peak hours instead, when the retail rate you'd otherwise pay is higher.

Ask any installer quoting you a North Carolina system to walk through your specific utility's current export rate structure and minimum bill, not a generic national average — this is one area where the details genuinely vary by utility and have been actively changing.

Backup Power: Not Just a Coastal Hurricane Question

North Carolina's outage risk doesn't fit neatly into one category the way it does in Florida or Texas. Coastal and eastern counties face direct hurricane landfall and tropical storm remnants. The Piedmont sees ice storms that can down power lines for days in winter. And western North Carolina, historically considered relatively insulated from major storm damage, saw that assumption upended by catastrophic flooding and widespread multi-day outages from Hurricane Helene's remnants in September 2024 — a storm that caused historic damage far inland, in mountain communities that hadn't planned around hurricane-scale outage risk at all.

The practical takeaway is that "backup power is only for coastal homes" doesn't hold up in North Carolina the way it might elsewhere. A standard grid-tied solar system, wherever it's installed in the state, shuts off automatically the instant utility power goes down — federally mandated anti-islanding protection that protects utility crews working on de-energized lines, not a system flaw. Panels sitting in full sun do nothing for your home during an outage unless you've paired them with a battery, a transfer switch, or portable backup power.

For whole-home coverage through a multi-day outage — refrigeration, well pump if you're on one, medical equipment, and enough capacity to keep the essentials running — a battery system like the EcoFlow Delta Pro 3 can be sized around the loads that matter most and recharged from portable solar panels even while a grid-tied system stays shut down under anti-islanding protection.

For households that want a lighter, more portable option — powering phones, a CPAP machine, a router, and a few essentials without the cost or installation complexity of a permanent home battery — something like the Jackery Explorer 2000 Plus covers the basics and travels with you if you evacuate ahead of a storm or lose power somewhere other than home.

Either option starts with an honest look at what you actually need to keep running and for how long, not a generic "whole house" assumption that inflates the cost of the decision.

A Realistic Checklist Before You Sign

Get your export rate structure in writing. Ask your installer or Duke Energy directly for the current time-of-use export rates and minimum bill that will apply to your account, not a general description of "net metering."
Confirm your property tax exemption is applied correctly. The 80% exemption is automatic under state law, but it's worth confirming with your county tax assessor's office after installation rather than assuming it happened.
Size around self-consumption, not just production. With export credits worth less than they used to be, a system and usage pattern that maximizes how much of your own solar you use directly will outperform one sized purely around annual production totals.
Ask whether your roof needs attention first. Given North Carolina's older housing stock in many markets, a straight answer on roof condition now saves a much bigger bill later.
Charge portable backup equipment before storm season, not during it. Whether you're in Wilmington or Asheville, a portable power station with no charge is dead weight when you actually need it.

The Bottom Line for North Carolina Homeowners

North Carolina's solar math was never built around a big state credit, so losing the federal credit changes the picture less dramatically here than in states that stacked both. What's actually shifting is the value of net metering itself — Duke Energy's move toward time-of-use export rates and a minimum bill means the old assumption of a flat, dollar-for-dollar credit no longer holds, and self-consumption now matters more than it used to.

The 80% property tax exemption remains a durable, automatic benefit worth factoring into your long-term cost. Beyond that, getting multiple real quotes, understanding your specific utility's export structure, and sizing backup power around the actual outage risk in your part of the state — coastal hurricanes, Piedmont ice storms, or the kind of inland flooding western North Carolina saw in 2024 — matter more than chasing an incentive that isn't there.
