Solar Panel Cost in North Carolina
Use published installed-price evidence and an exact state electricity-rate data point to pressure-test a proposal. The official policy sources below show which North Carolina utility and export assumptions to verify. Every price range is historical and labeled with its geography, year, sample, and limitations—not presented as a live quote.

No publishable 2024 state price distribution
The filtered Berkeley Lab file did not provide at least 20 qualifying North Carolina projects, our minimum for publishing a state percentile screen. We show the national distribution below rather than inventing a local average.
National 2024 installed-price comparison
Berkeley Lab reports that host-owned, stand-alone residential PV systems installed nationally in 2024 had a 20th-percentile installed price of $3.00/W, a median of $4.00/W, and an 80th percentile of $5.20/W in 2024 dollars before incentives.
We retain the national distribution as a consistent comparison across states. It is not a live state price, forecast, guarantee, or verdict. The source includes both cash and loan-financed purchases and excludes third-party-owned systems, paired storage, and self-installs.
National 2024 screen by system size
These examples multiply system watts by Berkeley Lab's national 20th-percentile, median, and 80th-percentile prices. They illustrate the math; they are not estimates of today's North Carolina market.
| System size | 20th percentile | Median | 80th percentile |
|---|---|---|---|
| 6 kW | $18,000 | $24,000 | $31,200 |
| 8 kW | $24,000 | $32,000 | $41,600 |
| 10 kW | $30,000 | $40,000 | $52,000 |
2024 USD, before incentives. A battery or unrelated roof and electrical work should be itemized before comparing solar-only price per watt.
Calculate price per watt for a North Carolina solar quote
Choose the proposed system size and optionally enter its cash or financed solar price before incentives. The tool calculates price per watt and shows the same published national historical screen alongside separately labeled North Carolina electricity-rate context.
North Carolina electricity-rate context: 16.25¢/kWh, from EIA's April 2026 preliminary residential average. This does not change the national installed-price screen or predict a household's savings.

Check my actual quote against thisHistorical national screen only — your quote depends on location, project scope, roof, equipment, financing, and installer. Confirm every material term in writing.
How many solar panels might a North Carolina system need?
State location alone does not determine panel count. The first arithmetic check is DC system watts divided by each panel's nameplate watts. These examples round up to a whole panel; the actual design still depends on usage, production, shading, roof layout, setbacks, and utility sizing rules.
| System size | At 400 W/panel | At 450 W/panel |
|---|---|---|
| 6 kW (6,000 W) | 15 panels | 14 panels |
| 8 kW (8,000 W) | 20 panels | 18 panels |
| 10 kW (10,000 W) | 25 panels | 23 panels |
North Carolina residential electricity price: April 2026
North Carolina's preliminary average was 16.25¢/kWh, 13.7% below the U.S. average of 18.83¢/kWh in the same EIA table. EIA labels the April values preliminary.
This statewide average provides context for the value of each kilowatt-hour a system might offset. It is not the tariff on a particular bill and cannot establish savings or payback by itself. Utility plan, usage timing, export compensation, production, financing, and system price all remain material.
How North Carolina policy changes the quote math
Duke Energy's Solar Choice Net Metering rules, effective for new participating residential customers from October 1, 2023, combine time-of-use and critical-peak pricing, minimum or non-bypassable charges, and avoided-cost treatment for net monthly exports. A capped Bridge Rate option and legacy transition provisions follow different terms.
- Modeling implication
- For a Duke account, model imports and self-consumption by time-of-use and critical-peak period, apply the current net-export credit, and retain minimum and non-bypassable charges. Do not assume a flat retail offset.
- State-specific decision context
- Rate-path eligibility matters: Solar Choice, the capped Bridge Rate, and a legacy arrangement can produce different results. The Public Staff notes a legacy transition date of December 31, 2026, so status should be confirmed rather than assumed.
- Utility caveat
- The cited Solar Choice and Bridge terms concern Duke Energy utilities. North Carolina municipal utilities and electric membership corporations can use different net-metering or avoided-cost programs.
State-selected inputs for a savings model
These are input instructions, not automatic defaults. Replace statewide context with the household's current bill and tariff.
- Rate context
- EIA April 2026 preliminary average: 16.25¢/kWh.
- Import price
- Use the actual utility, supplier, rate plan, fixed charges, and time periods from the bill.
- Export value
- Use the current written utility tariff or provider agreement; do not substitute the statewide average.
- Usage and production
- Use monthly or interval data when tariff timing, annual reconciliation, or self-consumption changes the result.
Three questions to put in writing
- Is the account eligible for Solar Choice, the Bridge Rate, or a legacy arrangement?
- Does the model include time-of-use, critical-peak, minimum, and non-bypassable charges?
- What avoided-cost value is applied to net monthly exports, and from which tariff version?
Policy record reviewed July 23, 2026. Next scheduled review October 23, 2026. A tariff can change sooner, so verify it again before signing.
How to use the screen on your quote
- Find the installed price before incentives and the DC system size. Separate batteries, roof work, or unrelated add-ons.
- Divide price by watts. For example, $32,000 divided by 8000 watts is $4.00/W.
- Compare the result with the national historical distribution, while checking whether your project matches the source's scope.
- Ask for written explanations of major scope, equipment, roof, permitting, or financing differences. A percentile is a prompt for questions, not proof that a quote is good or bad.

North Carolina solar cost data: FAQ
- How much do solar panels cost in North Carolina?
- We do not publish an invented current North Carolina average because the filtered Berkeley Lab file does not provide at least 20 qualifying 2024 projects for this state. The national 2024 screen is $3.00/W at the 20th percentile, $4.00/W at the median, and $5.20/W at the 80th percentile before incentives.
- How do I calculate price per watt on a solar quote?
- Divide the installed price before incentives by the system's DC watts. For example, an 8 kW system has 8000 watts, so $32,000 divided by 8000 is $4.00 per watt. Itemize batteries, roof work, and unrelated add-ons before comparing the solar portion.
- How many solar panels do I need in North Carolina?
- Panel count starts with system size, not the state name. Divide DC system watts by the module rating: an 8 kW system is 8,000 watts, or about 20 panels at 400 watts each. The final design must use the home's annual usage, expected production, roof planes, shading, setbacks, module rating, and the serving utility's sizing rules; round up only after confirming the layout and usable capacity.
- How should I model exported solar energy in North Carolina?
- For a Duke account, model imports and self-consumption by time-of-use and critical-peak period, apply the current net-export credit, and retain minimum and non-bypassable charges. Do not assume a flat retail offset. The cited Solar Choice and Bridge terms concern Duke Energy utilities. North Carolina municipal utilities and electric membership corporations can use different net-metering or avoided-cost programs.
- What is the residential electricity price in North Carolina?
- North Carolina's preliminary average was 16.25¢/kWh, 13.7% below the U.S. average of 18.83¢/kWh in the same EIA table. These are April 2026 preliminary statewide averages from EIA, not a promise of the tariff or bill savings for a particular household.
- Does North Carolina's electricity price show whether solar is worth it?
- No. The state average is one input, but a household decision also depends on its utility tariff, usage timing, roof and shading, system production, installed price, financing, export compensation, maintenance, and contract terms. Use the rate as context, not a suitability verdict.
- What projects does the Berkeley Lab price screen cover?
- It covers host-owned, stand-alone residential PV installed in 2024 and reports prices in 2024 dollars per DC watt before incentives. It includes cash and loan-financed systems and excludes third-party-owned, paired-storage, and self-installed systems.
