What solar costs in North Carolina
Berkeley Lab does not have enough reported installations in North Carolina to publish a reliable local price, so the figures below use the national median. Treat them as a starting point, not a quote.
The numbers
High electricity prices make solar pay faster, so a red figure in the third box is good news for a solar buyer and bad news every other month of the year.
Holding a quote above $30,000? Installers in North Carolina price the same system very differently. Two more bids is the cheapest way to find out where yours sits.

What the roof makes month by month in Charlotte
A 1.8 to 1 swing, which is unusually flat. Output here is steadier month to month than almost anywhere else in the country, so monthly bills stay more predictable.
Figures are for an 8 kW array at 20 degrees facing south, modelled from NSRDB radiation data at Charlotte.
What different sizes cost in North Carolina
| Size | Panels | Price | Output | Year one saving | Payback |
|---|---|---|---|---|---|
| 4 kW | 10 | $15,000 | 5,480 kWh | $831 | 15.6 years |
| 5 kW | 13 | $18,750 | 6,850 kWh | $1,038 | 15.6 years |
| 6 kW | 15 | $22,500 | 8,220 kWh | $1,246 | 15.6 years |
| 7 kW | 18 | $26,250 | 9,590 kWh | $1,454 | 15.6 years |
| 8 kWtypical | 20 | $30,000 | 10,960 kWh | $1,662 | 15.6 years |
| 10 kW | 25 | $37,500 | 13,700 kWh | $2,077 | 15.6 years |
| 12 kW | 30 | $45,000 | 16,440 kWh | $2,492 | 15.6 years |
| 15 kW | 38 | $56,250 | 20,550 kWh | $3,115 | 15.6 years |
| 20 kW | 50 | $75,000 | 27,400 kWh | $4,154 | 15.6 years |
Payback is the same at every size because this table holds the price per watt flat at the national median of $3.75: price and output both grow in step with the system, so their ratio does not change. Real quotes are not quite linear. Permitting, design and connection cost roughly the same on any roof, so a small system usually costs more per watt and a large one less, and pays back correspondingly later or sooner than shown.
North Carolina has too few reported installations for a local median, so the price is the national median of what households paid on host-owned systems installed in 2024-2025, compiled by Berkeley Lab. Local quotes can sit well above or below it.
8 programmes in North Carolina
The 30% federal credit ended for installations completed after 31 December 2025. These state, utility and local programmes are unaffected by that, and are now the only thing that reduces the price.
| Programme | Type | Run by | Reach | Updated |
|---|---|---|---|---|
| Active Solar Heating and Cooling Systems Exemption | Property Tax Incentive | State | statewide | November 17, 2025 |
| Blue Ridge EMC - Net Metering | Net Metering | Utility | statewide | March 27, 2026 |
| Duke Energy - PowerPair | Rebate Program | Utility | statewide | February 11, 2026 |
| Interconnection Standards | Interconnection | State | statewide | June 7, 2024 |
| Net Metering | Net Metering | State | statewide | February 27, 2026 |
| Property Tax Abatement for Solar Electric Systems | Property Tax Incentive | State | statewide | March 23, 2026 |
| North Carolina Solar Rights | Solar/Wind Access Policy | State | partial | February 18, 2026 |
| South River EMC - Solar Water Heating Rebate Program | Rebate Program | Utility | partial | February 6, 2025 |

Solar in North Carolina, answered
How much do solar panels cost in North Carolina?
An 8 kW system in North Carolina, roughly 20 panels, costs about $30,000 before incentives. That is based on $3.75 per watt, the national median from Lawrence Berkeley National Laboratory for 2024-2025, because too few North Carolina installations are reported to publish a local figure. There is no longer a federal tax credit to subtract from that figure.
Is there still a 30% solar tax credit in North Carolina?
No. The federal Residential Clean Energy Credit under Internal Revenue Code section 25D was terminated by the One Big Beautiful Bill Act for expenditures made after 31 December 2025, and it did not step down first. A North Carolina homeowner buying a system with cash or a loan today receives no federal tax credit. Under a lease or power purchase agreement the credit survives as section 48E but belongs to the company that owns the equipment, not to the household. North Carolina still has 8 state, utility or local programmes covering rooftop solar.
How long do solar panels take to pay for themselves in North Carolina?
About 15.6 years in North Carolina. An 8 kW system costs roughly $30,000 and saves about $1,662 in its first year at the state's average residential rate of 15.16 cents per kilowatt-hour (EIA, July 2026). That calculation includes no federal tax credit, because the residential credit ended after 31 December 2025.
How much electricity does a solar panel produce in North Carolina?
Each kilowatt of panels in North Carolina produces about 1,370 kilowatt-hours a year, modelled at Charlotte facing south at a 20 degree tilt using NSRDB radiation data. An 8 kW system therefore makes roughly 10,960 kilowatt-hours a year. The national average is about 1,332 kilowatt-hours per kilowatt installed.
Is solar worth it in North Carolina?
It depends less on sunshine than on your electricity price. In North Carolina power costs 15.16 cents per kilowatt-hour (EIA, July 2026), which makes an 8 kW system pay for itself in about 15.6 years and clear roughly $23,135 over 25 years. Solar from your own roof works out at 11.6 cents per kilowatt-hour over its life, against 15.16 cents from the utility.
How many solar panels do I need in North Carolina?
A typical North Carolina installation is about 20 panels, which is 8 kW at the 400 watt module that is now standard and needs roughly 440 square feet of roof. To size it to your own use, divide your annual kilowatt-hours by 1,370, which is what each kilowatt of panels produces in North Carolina each year.
Do solar panels work in winter in North Carolina?
Yes, but output falls sharply. In Charlotte a kilowatt of panels makes about 140 kilowatt-hours in May and about 80 in Dec, a swing of 1.8 to 1 across the year. A system sized to cover your annual consumption will therefore run a surplus in summer and leave you buying power in winter, so how your utility settles that difference matters as much as the size of the array.
Three competing quotes beat any amount of comparing panel brands
Sales cost and margin are over a third of an installed price in North Carolina, and they are the part that competition removes. A single quote from whoever reached you first is how people end up in the top quarter of what their neighbours paid.

Prices and rules change. We will tell you when they do
Berkeley Lab publishes installed prices once a year, the EIA updates electricity rates every month, and Congress changed the tax treatment of all of this in 2025. One email when something on this site actually changes, and nothing else.
