North Carolina Solar Incentives, Net Metering, and Cost Guide (2026)
Solar can work well in North Carolina, but your savings depend on your utility's net metering tariff, your home's usage pattern, and whether you add a battery. This guide breaks down incentives, bill credits, costs, and how to compare quotes with fewer surprises.
What's Different About Going Solar in North Carolina
North Carolina is a top solar state overall, but the homeowner experience can be very different depending on whether you're in Duke Energy Carolinas or Duke Energy Progress territory, Dominion Energy North Carolina territory, or served by a municipal utility or cooperative. The "right" solar design is usually the one that matches your utility tariff and your household's day-to-day energy use—especially how much power you use in the evening versus midday.
A practical first step is simply identifying your electric provider and rate schedule. That one detail determines how exported solar energy is credited and what extra charges or time-of-use requirements may apply.
Solar Costs in North Carolina
Pricing varies by roof shape, system size, equipment, and electrical work (like a main panel upgrade). For planning, it helps to think in ranges rather than a single "average."
| System size | Common fit for | Planning price range |
|---|---|---|
| 5 kW | Smaller homes, lower annual usage | $13,000–$22,000 |
| 7.5 kW | Many average-usage homes | $18,000–$30,000 |
| 10 kW | Higher usage / more electric loads | $24,000–$40,000 |
These are broad planning ranges—not quotes. Your roof condition, wiring distance, attic access, and whether you add a battery can shift pricing materially.
How Much Can Solar Save in North Carolina
Most savings come from two buckets: using your own solar production in real time (self-consumption) and earning bill credits for what you export. The balance between those two matters more under modern net metering designs because the value of exports may not match the full retail rate in every situation.
In Duke territories, the NC Public Staff notes that revised riders can include new charges and TOU-related requirements depending on the rider, which can change how solar savings show up on your bill.
Payback drivers that tend to matter most
| Factor | Typically improves payback when… | Typically slows payback when… |
|---|---|---|
| Daytime usage | You run HVAC, laundry, EV charging, or pool pumps midday | Most usage happens after sunset |
| Rate design | Your rate/tariff rewards exports or peak-shaving | Export credits are lower; fixed charges are higher |
| Roof & shading | Large, unshaded south/west roof planes | Heavy tree shading or complex roof planes |
| Electrical work | No major upgrades required | Panel/service upgrades or reroofing needed |
| Battery choice | Incentives + outage value justify cost | Battery added mainly for "nice to have" backup |
Incentives and Credits for North Carolina Solar
Federal Residential Clean Energy Credit (Solar + Battery)
The IRS states the Residential Clean Energy Credit is 30% of qualifying costs for eligible clean energy property installed from 2022 through December 31, 2025, and that it is not available for property placed in service after that date. The IRS also provides guidance on claiming the credit and the related Form 5695 instructions.
Because this is a placed-in-service deadline, the practical takeaway is: if you're trying to qualify, schedule with enough buffer for permitting, installation, inspections, and utility approval.
North Carolina property tax treatment for solar
North Carolina's property tax system references G.S. 105-275(45) (Solar energy electric system) in the NCDOR AV-10 application used for certain exemptions/exclusions handled through local property tax administration.
Important update to verify: A UNC School of Government legislative summary indicates H 729 (2025–2026) amended G.S. 105-275(45) and changed the exclusion level effective July 1, 2025. If you're installing solar, confirm how your county assessor applies the current statute to your system type (residential vs income-producing, owned vs leased, etc.).
Utility / program incentives (solar + storage)
If you're in Duke territory and considering a battery, Duke's PowerPair program materials describe one-time incentives for eligible solar + battery installations completed through participating installers and program requirements that can change with capacity and equipment eligibility.
Because program funding and eligibility can fill up or change, treat this as a "verify now" item while getting quotes.
Incentives checklist
| Incentive / program | Who it's for | How you get it | What to verify |
|---|---|---|---|
| Federal Residential Clean Energy Credit | Eligible taxpayers | Claim on federal return (Form 5695) | IRS placed-in-service deadline + eligible costs |
| NC property tax exclusion/exemption pathway | NC property owners (case-specific) | Administered locally (county) | Current version of G.S. 105-275(45) + county application practice |
| Duke PowerPair (solar + battery) | Eligible Duke NC customers | Through approved process/installer | Program capacity, eligible equipment, and current terms |
Net Metering and Solar Compensation in North Carolina
Duke Energy Carolinas / Duke Energy Progress
The NC Public Staff explains that revised net metering riders for residential customers became effective October 1, 2023, including a "Residential Solar Choice" rider and a "Net Metering Bridge" option, with requirements and charges that can include TOU-related service and non-bypassable charges (details depend on rider and system size).
The practical point: two homes with the same solar system can see different savings if their usage patterns differ (especially evenings), or if they're on different rider options.
Dominion Energy North Carolina
Dominion's net metering page describes how the program allows customers to interconnect approved renewable generation systems and use net metering as part of their billing under Dominion's rules.
Example: simple bill-credit math (illustrative)
Assume your home uses 900 kWh in a month and your solar produces 750 kWh.
- •If you use 300 kWh instantly, you still buy 600 kWh from the grid (900 − 300). You export 450 kWh (750 − 300).
- •Your bill outcome then depends on how exported energy is credited under your utility tariff and rider choice—some structures behave closer to classic netting while others apply bill credits with additional riders/charges and TOU components.
When comparing quotes, ask each installer to spell out which net metering tariff/rider they modeled and what assumptions they used for export credits.
North Carolina Solar Potential and Production Notes
North Carolina is generally favorable for solar, but a realistic design accounts for heat, humidity, summer peak cooling loads, and storm resilience. In many parts of the state, shading from mature trees is the biggest production killer—often more important than panel brand. A good proposal should include a shade analysis and a production model that matches your roof planes (not a generic county average).
Sizing a Solar System in North Carolina
A homeowner-friendly sizing method starts with your annual usage (kWh) from your utility bills and then works backward into a rough kW target—before refining with roof layout and shading.
Example: kWh → kW starting point (illustrative)
If your household uses 10,000 kWh/year and a preliminary production assumption is roughly 1,200–1,400 kWh per installed kW per year (roof- and location-dependent), a starting point might be around 7–8.5 kW. Final sizing should be adjusted after a shade study and after confirming any utility sizing requirements tied to historical usage.
Batteries and Backup Power in North Carolina
Batteries typically serve one of two goals: backup during outages or shifting solar energy into evening hours for bill savings. If you're in Duke territory, it's worth checking whether your project qualifies for PowerPair incentives and whether program capacity is still available at the time you apply.
When evaluating batteries, ask for a clear critical loads plan (what stays on during an outage) and a realistic runtime estimate based on your home's essentials.
Permitting and Interconnection
Most North Carolina projects follow the same broad sequence: site survey and design, permitting, installation, inspection, utility interconnection steps, and then Permission to Operate (PTO). The timeline varies by jurisdiction and utility workload.
| Stage | Timeline |
|---|---|
| Permitting | 1–3 weeks (varies by jurisdiction) |
| Installation & inspection | 2–4 weeks |
| Utility interconnection & PTO | 2–8 weeks (utility-dependent) |
Many homeowners see a multi-week process from signing to installation, then additional weeks for inspections and utility steps before PTO. Delays often come from permit corrections, electrical upgrades, reroofing, or interconnection paperwork.
How to Choose a Solar Installer in North Carolina
A strong quote is one that matches your utility tariff, explains export-credit assumptions clearly, and includes all required electrical work in the scope. In Duke territories, where rider options and TOU-related components can change bill outcomes, it's especially important that the proposal isn't using a simplistic one-to-one net metering forever assumption.
Example: apples-to-apples quote comparison (illustrative)
Installer A shows bigger 25-year savings because they assume higher export credit value and don't include a needed panel upgrade. Installer B models your rider/rate more conservatively and includes the upgrade. The second quote can be the better deal even if the headline savings number is smaller—because it's closer to what your bill will actually do.
