Solar panel cost in North Carolina (2026)

Installing solar in North Carolina costs about $2.60 per watt before incentives — roughly $20,800 for a typical 8-kilowatt system. Use the calculator above to adjust for your roof orientation, system size, and monthly usage.

What shapes the solar panel cost in North Carolina

Three variables set your baseline: what electricity costs, how much sun your roof captures, and what contractors charge per watt.

North Carolina’s average residential rate is 12.5 cents per kilowatt-hour — below the national average. Every kilowatt-hour your panels produce offsets 12.5 cents in grid purchases. In states where rates run 25–30¢, the same system pays back in roughly half the time. NC’s lower rate means a longer payback timeline; the math has to hold at 12.5¢, not someone else’s.

North Carolina averages 4.8 peak sun hours per day on a well-oriented south-facing roof — ahead of most of New England and the Midwest, and comparable to parts of Texas.

The $2.60/watt installed figure is a statewide median. It covers panels, inverter or microinverters, racking hardware, conduit and wiring, permits, and labor. Higher-efficiency N-type TOPCon or HJT panels push quotes toward $3.00/watt and above; a competitive installer with a standard monocrystalline PERC system can sometimes come in under $2.50/watt.

Cost by system size

The table below applies $2.60/watt across four common system sizes. Annual output is estimated using 4.8 peak sun hours, 365 days, and an 80% efficiency factor that accounts for inverter losses, temperature derating, wiring, and typical shading. Monthly bill offset uses 12.5¢/kWh. All figures are estimates.

System size	Installed cost estimate	Est. annual output	Est. monthly bill offset
5 kW	~$13,000	~7,000 kWh	~$73
8 kW	~$20,800	~11,200 kWh	~$117
10 kW	~$26,000	~14,000 kWh	~$146
12 kW	~$31,200	~16,800 kWh	~$175

The average North Carolina household uses 1,100–1,150 kWh per month, so an 8–10 kW system offsets the bulk of a typical bill. If you have an EV charger, electric heat pump, or pool equipment, plan for the higher end of that range or larger.

A worked example

Say you use 1,000 kWh per month and your bill averages $125. An 8 kW system generates roughly 11,200 kWh per year — about 930 kWh per month — covering most of your usage. At 12.5¢/kWh, that’s approximately $1,400 per year in avoided electricity costs.

At an installed cost of $20,800 with no federal or state tax credit, a rough simple payback lands around 15 years. That shortens if electricity rates rise — historically they have — and lengthens if production runs lower than estimated or net metering credits are valued below retail. The calculator above runs this with your actual bill and usage profile.

Incentives available in 2026

Federal tax credit (§25D): $0 for 2026 homeowner purchases. The residential solar Investment Tax Credit expired December 31, 2025, under the One Big Beautiful Bill Act. Homeowners who purchased and installed in 2025 could claim the 30% credit on their 2025 return. For systems placed in service in 2026 and beyond, §25D does not exist. Any installer or website still advertising a 30% federal credit for a new 2026 installation is out of date — don’t factor that credit into your decision without confirming the law has changed.

One nuance: if you lease your system or sign a power purchase agreement (PPA) with a third-party owner, that company may still access the commercial Investment Tax Credit (§48E) and pass some savings through in lower contracted rates. Ask any leasing company specifically how the commercial credit flows to your pricing.

North Carolina state tax credit: not available. The state’s residential solar credit expired in 2015 and was never renewed.

Property tax exclusion: active and worth having. North Carolina provides an 80% exclusion on the assessed value a solar system adds to your home. If your installation adds $20,000 in home value, only $4,000 of that is subject to property taxes. This exclusion applies over the system’s full life — typically 25 years or more. Confirm with your county assessor how it applies in your area.

Utility and co-op rebates: varies by provider. Some electric cooperatives and smaller municipal utilities offer upfront rebates or bill credits. These programs change frequently and differ by territory. Ask your installer what your specific utility offers and verify it directly with the utility before signing a contract.

How Duke Energy’s net metering affects your value

Duke Energy’s residential time-of-use tariff credits you for surplus power exported to the grid — but the value depends on when you export. On-peak exports earn a higher rate; off-peak exports earn less. This differs from flat-rate net metering and affects how you should size and potentially store your solar output.

A household that runs HVAC and appliances during peak hours consumes its own solar at high-value times — a good outcome. A home empty during the day exports heavily at off-peak rates, cutting the effective value of those panels. A battery lets you shift that surplus into the evening peak, either capturing higher credit rates or avoiding higher-rate grid purchases.

Duke also charges a small minimum monthly bill for net-metered residential customers. Even if your panels cover 100% of consumption in a given month, you’ll still owe a base charge. It’s modest for most customers, but it belongs in your savings estimate.

If you’re served by a co-op or municipal utility rather than Duke, net metering terms can differ substantially — sometimes more favorable, sometimes less. Confirm the exact tariff with your specific provider before sizing your system.

What drives your specific quote up or down

Roof complexity. A simple single-plane south-facing roof is the cheapest to work on. Multiple pitches, dormers, skylights, or a clay tile roof add both labor and hardware costs.

Equipment tier. Premium panels — higher wattage, better low-light performance, 25- to 30-year product warranties — cost more per watt. Microinverters typically cost more upfront than a string inverter but perform better with uneven shading and make future expansion simpler.

Battery storage. A home battery adds roughly $10,000–$18,000 or more. Given Duke Energy’s time-of-use structure, storage can make strategic sense: hold midday surplus rather than exporting at an off-peak rate, then discharge during the evening peak. Run the numbers for your specific tariff before deciding.

Permitting and interconnection. Costs vary by jurisdiction and utility. These should appear as explicit line items in any legitimate quote — confirm they’re included rather than added later.

How to get an honest quote

Get at least three itemized bids from licensed North Carolina contractors. Each quote should break out panels, inverter(s), racking, electrical work, permits, interconnection fees, and labor as separate line items. A quote showing only a monthly financing payment without total installed cost, interest rate, and term is not giving you what you need to evaluate the deal.

Ask every installer:

• What is the total installed cost before financing?
• What production estimate does the quote assume, and which modeling tool generated it?
• What is my specific utility’s net metering tariff, and how does this system interact with it?
• What warranties cover panels, inverter, and workmanship separately?

Whether solar panels are worth it for your home comes down to your roof, your tariff, your bill, and your timeline for staying in the house. The calculator above applies all of those inputs.

Verify all incentive eligibility with the relevant agency or a qualified tax professional before making any purchase decision. Incentive programs change faster than articles do, and what applies at the time of writing may not apply by your installation date.
