Why this number
A kilowatt of panels in Charlotte produces about 1,431 kWh a year, the highest of the 2 North Carolina cities modeled here — ahead of Raleigh at 1,424. On an 8 kW system that is a payback of about 20.7 years, against 20.8 years in Raleigh, on identical hardware at the same 15.16¢/kWh.
Charlotte against the rest of North Carolina
Two North Carolina cities have their own modeled figures, and they are only 0.5% apart — Raleigh at 1,424 kWh per kW against Charlotte at 1,431, which is a remarkably narrow gap by the standards of this dataset. The rate, the export rule and the $2.35/W installed cost are identical for both; only production moves.
| Location | kWh per kW per year | 8 kW output | Annual value | Payback |
|---|---|---|---|---|
| Charlotte (this page) | 1,431 | 10,303 kWh | $906 | 20.7 yrs |
| Raleigh | 1,424 | 10,253 kWh | $902 | 20.8 yrs |
| North Carolina state average | 1,375 | 9,900 kWh | $870 | 21.4 yrs |
Against the state figure, Charlotte runs 4.1% above North Carolina’s 1,375 kWh per kW — a payback 0.9 years longer than the statewide 21.4-year estimate on the same hardware at the same price.
What sets Charlotte apart
Duke Energy Carolinas territory.
Your utility, officially
North Carolina’s average residential rate is 15.2¢/kWh, but the bill in Charlotte comes from Duke Energy Carolinas at 13.94¢ — 8.0% below the state figure. These are the residential figures Charlotte’s utility reported to the U.S. Energy Information Administration on Form EIA-861 for 2024 — computed as revenue ÷ sales from the official file, not estimated:
| Utility | EIA ID | Residential avg price | Residential customers | Net-metering (residential, self-reported) |
|---|---|---|---|---|
| Duke Energy Carolinas | 5416 | 13.94¢/kWh | 1,919,372 | 24648 customers / 179.097 MW |
How exports are treated matters as much as the headline price: Duke Energy Carolinas is modeled here under the state’s net billing rules, and that treatment is baked into every payback figure on this page.
Charlotte is billed by Duke Energy Carolinas, LLC — investor-owned, 1,919,372 residential customers, and a 2024 EIA-861 average of 13.94¢/kWh. Hold that number next to Raleigh’s before doing anything else. Raleigh is served by Duke Energy Progress, a legally separate Duke operating company, at 15.54¢ — about 11% more — while the two cities’ solar resources are nearly identical: 1,431 kWh per kW of unshaded south-facing capacity in Charlotte against 1,424 in Raleigh, a half-percent apart. Same brand on the truck, same sun overhead, meaningfully different economics. The line that separates a Charlotte payback from a Raleigh one is a utility service boundary, not anything in the sky.
The export regime is the same statewide, and it is not the old full-retail deal. North Carolina moved to Residential Solar Choice (RSC), a net-billing framework effective October 1, 2023, under which exported energy is credited below the retail rate. The practical consequence: a kilowatt-hour you consume as it is generated offsets the full 13.94¢, while one you send to the grid earns less, so daytime self-consumption — running the water heater, the pool pump, the dryer while the array produces — does real work here, and system sizing should follow your actual daytime load rather than your annual total. At best-case self-consumption, each installed kilowatt displaces roughly $199 of retail electricity a year; the exported share earns less, and Charlotte’s cheap retail rate means every displaced kilowatt-hour is worth a bit less than it would be in Raleigh to begin with.
Adoption is real but not dense: Duke Carolinas reported 24,648 residential net-metering customers and 179.097 MW to EIA for 2024, about one home in seventy-eight, with an average system a bit over 7 kW.
On money in, keep the ledger honest. The federal §25D residential credit is $0 for cash and loan purchases in 2026 — it expired December 31, 2025 — and 30% survives only on leases and power-purchase agreements through the separate §48E business credit, where the lessor claims it and competition decides how much reaches your monthly payment. North Carolina’s own residential solar tax credit expired years ago and has not returned. What the state does still offer is a full property-tax exemption on the added home value. The bright spot is upfront cost: at an EnergySage marketplace average of $2.35/W before incentives, North Carolina is one of the cheaper states in the country to build in — which, under net billing at 13.94¢, is exactly the variable doing the heavy lifting.

Who else serves the metro
Most of Charlotte falls under Duke Energy Carolinas, but its 63-county EIA-861 footprint also includes Duke Energy Progress at 15.5¢, EnergyUnited EMC at 11.5¢, and Broad River Electric Cooperative at 15.9¢. Against Duke Energy Carolinas’s 13.94¢, that’s about a 2.4¢ drop to EnergyUnited and a 2.0¢ climb to Broad River, a range wide enough to move a payback estimate meaningfully, particularly since a cooperative like EnergyUnited sets its own export policy separately from Duke’s. North Carolina’s July 2026 state average, 15.16¢, is a later figure and shouldn’t be treated as interchangeable with these 2024 rates. A property’s ZIP code, not the city on its mailing address, is what actually determines which utility serves it.
| Utility (EIA-861, same service counties) | 2024 avg residential price | Residential customers |
|---|---|---|
| Duke Energy Progress - (NC) | 15.5¢/kWh | 1,356,079 |
| EnergyUnited Elec Member Corp | 11.5¢/kWh | 121,995 |
| Rutherford Elec Member Corp | 13.1¢/kWh | 70,743 |
| Broad River Electric Coop, Inc | 15.9¢/kWh | 23,140 |

An 8 kW system in Charlotte, priced out
| Metric | Estimate for Charlotte | North Carolina statewide |
|---|---|---|
| Production, unshaded 20° south | 1,431 kWh per kW/yr | 1,375 kWh per kW/yr |
| 8 kW output after a 10% roof derate | ~10,303 kWh/yr | ~9,900 kWh/yr |
| Average residential rate | 15.2¢/kWh (EIA) | 15.2¢/kWh |
| Installed cost, 8 kW | ~$18,800 at $2.35/watt | ~$18,800 |
| 2026 federal credit | $0 | $0 |
| Export rule | Net billing — exports credited below retail | Net billing — exports credited below retail |
| Export credit modeled | 4.55¢/kWh | 4.55¢/kWh |
| Annual value of that output | ~$906 | ~$870 |
| Rough payback (your utility) | 22.3 years | 21.4 years (state-average model) |
| 25-year net position | $4,421 | — |
Only the first two rows differ. Everything financial — rate, tariff, price per watt — is inherited from North Carolina without change, which is the point: a city page that quietly used a different electricity rate from its state page would be guessing, not measuring.
Doing nothing is not free either. Twenty-five years of the electricity an 8 kW Charlotte array would produce, with rates rising at 2.5% a year, comes to roughly $53,354.
If an EV charges at the Charlotte house, the EV + TOU + whole-home calculator prices that charging against this same solar output.
Run it with your own bill
Shared methodology · identical on every city page
- Production figures are unshaded, south-facing, 20° PVGIS values. A real roof — its own pitch, orientation, a tree or a chimney — typically produces 10–25% less; every payback here already carries a 10% real-roof derate.
- Paybacks include $150/yr of running costs and one $2,000 inverter replacement in year 14, which is why they run longer than paybacks quoted elsewhere.
- State export rules cover investor-owned, state-regulated utilities. Municipal utilities and rural electric cooperatives are exempt in most states and set their own terms.
- Installed cost is the state-level EnergySage market figure, not a city quote; a swing of 50¢/W moves payback by roughly a year and a half either way. Get three quotes before trusting any payback — including ours.
Charlotte against the rest of North Carolina
Same rate, same export rule, same installed price per watt — only the sunshine changes:
| City | kWh per kW | Payback |
|---|---|---|
| Charlotte | 1,431 | 20.7 years |
| Raleigh | 1,424 | 20.8 years |
A 0.5% production span across one state is the reason a single statewide number is only ever a starting point.
What North Carolina pays Charlotte for exported power
North Carolina does not credit exports at the retail rate, and that rule reaches Charlotte unchanged. The program is Residential Solar Choice (RSC) , in force since 2023-10-01, crediting surplus power at an assumed 4.5¢/kWh, about 30% of retail, because no per-kWh figure is published against a retail rate of 15.2¢.
Because a typical home uses only about 40% of its generation as it is produced, most of what a Charlotte array makes is sold at that lower rate. That is why the payback above is 22.3 years and not the 11.8 years the same hardware would return under full-retail net metering. Raising self-consumption is the lever that closes the gap.
Sources and method
- Production: modeled with PVGIS v5.2 PVcalc (European Commission JRC) using the PVGIS-NSRDB radiation database — the same NREL satellite dataset PVWatts draws on for the Americas. Assumptions: 4 kWp, standard c-Si, 14% system loss, roof mounting, 20-degree tilt, due south, horizon shading on. The 1,431 kWh per kW figure for Charlotte is a modeled location point, not an interpolation from the North Carolina average. PVGIS is free to use with JRC attribution requested; the underlying NSRDB is public domain (NREL/DOE).
- Real-roof derate: a separate 10% deduction for azimuth, pitch and shading, applied in the shared model rather than folded into the production data — so you can adjust it if your roof is genuinely unobstructed.
- Electricity rate: U.S. Energy Information Administration, average price by state . This is North Carolina’s residential average; EIA does not publish a Charlotte figure, so the state rate is used and labeled as such.
- Export rules: Residential Solar Choice (RSC) , from our North Carolina state page and the shared export-rules dataset behind it.
- State average rate: EIA Table 5.6.A, July 2026 data (released Sep 2026), used for every state-average comparison on this page.
- Payback model: shared with the solar savings calculator and the state pages — 2.5%/yr utility inflation, 0.5%/yr degradation, $150/yr running costs, one $2,000 inverter replacement in year 14, federal credit $0. The rest of the toolset — battery, sizing, financing — is under all calculators .
- Incentives: DSIRE . City and utility programs change more often than state ones — check yours directly.
Electricity rate, export regime, production figure and installed cost on this page were last verified on 30 August 2026. Export credits reset on annual tariff cycles and incentive budgets run out mid-year, so treat every figure as a snapshot at that date and confirm current terms before acting. Nothing here is tax or financial advice.
Frequently asked questions
How much do solar panels cost in Charlotte in 2026?
About $18,800 for a typical 8 kW system at $2.35 per watt, before any incentive. With the federal credit at $0 in 2026 that is close to your net cost. Note that the price per watt is a North Carolina market average — there is no reliable city-level cost data, so treat it as a starting point and get three quotes.
What is the solar payback in Charlotte?
Roughly 22.3 years on this model, using Charlotte’s own production figure of 1,431 kWh per kW and its own utility tariff (13.94¢/kWh) with each utility’s real export treatment. That includes $150 a year of running costs and one inverter replacement, which many published paybacks leave out.
Is Charlotte better or worse for solar than the rest of North Carolina?
Against the state figure, Charlotte runs 4.1% above North Carolina’s 1,375 kWh per kW — a payback 0.9 years longer than the statewide 21.4-year estimate on the same hardware at the same price.
Is solar worth it in Charlotte in 2026?
At 15.16¢/kWh and 1,431 kWh per kW, an 8 kW system in Charlotte pays back in about 20.7 years on this model. Treat that as a starting point for reading real quotes rather than as a quote: your roof’s orientation, its shading and the price you are actually offered will move it more than your city does.
How we calculated this
Year-1 saving = production (kW × the city’s modeled kWh per kW) × the blended kWh value (retail rate for self-use, the state export rule for exports). Payback = net cost ÷ year-1 saving, with the federal credit at $0 for 2026 purchases and cost per watt from the state’s installed-price band. Production is modeled from PVGIS/NSRDB irradiance for the city.Sources: U.S. Energy Information Administration (EIA) electricity rates · DSIRE incentive records · public IRS/OBBBA guidance.
