North Carolina Solar: Your Filing Date Picks Your Duke Plan
Written by Dean Mahmoud, CEO, and checked by Trevor Guilday, founder.Prices from the September 2026 Cost Index. Duke riders re-read October 14, 2026. Updated October 19, 2026.
A typical North Carolina home system is 9.76 kW and costs about $26,938 in cash at $2.76 per watt. With Duke Energy Carolinas, the largest utility, it pays for itself in about 28.4 years on the Bridge plan (24.2 to 33.0 years, set by how much power is left over each month) and in at least 16.7 years on Residential Solar Choice, simple payback before incentives. Duke’s Bridge plan takes new requests only until December 31, 2026.

Duke’s Net Metering Bridge closes to new requests on December 31, 2026
Since October 1, 2023, a new Duke solar home goes on one of two billing plans. Both credit leftover power at the same low rate. They differ in how you pay for the power you buy, and the date your installer files the interconnection request decides which one you can get.
Net Metering Bridge until Dec 31, 2026
You stay on a normal home price plan.
Exports cancel power you buy in the same month, kWh for kWh.
You keep the plan for up to 15 years from the date of your interconnection request.
Residential Solar Choice no closing date
You move to a time-of-use plan: power costs more at busy hours and during peak events.
Exports are netted within each price period.
What is left in a period at month’s end earns the same 4.53¢ or 3.94¢ credit. It carries to later bills, with no yearly reset.
Dec 31Last day to file for the Bridge
The rider closes to new participants on January 1, 2027.

Counted from your interconnection request, then you move to Solar Choice or a later plan.
20 kW ACSize limit on both plans
Or your home’s estimated highest monthly demand, if that is lower.
Duke reserves Bridge room when a valid interconnection request is filed, not when you sign a contract. A contract signed in December does not help if the request goes in after December 31, 2026, or after that year’s room is used up. Then the home goes on Solar Choice.
Already have Duke solar from before October 2023?
Homes on Duke’s older net metering rider keep it only until December 31, 2026. Duke must move them to the Bridge or another newer plan by January 1, 2027. Expect a monthly solar charge and a minimum bill after the move.
Duke Energy Carolinas payback turns on what is left at month’s end
On both Duke plans, solar power you send out first cancels power you buy in the same month. Only what is left when the month closes earns the low credit. Our per-utility figures give one case for each Duke plan.

On the Bridge, the more of your solar power you use at home or cancel within the month, the shorter the payback: 24.2 years at 55% used at home, 33.0 years at 28%. The Solar Choice figure prices every kWh at Duke’s average less its customer charge, so a real Solar Choice home takes longer.
How we calculated this
Output: 9.76 kW × 1,407 kWh per kW = 13,732 kWh a year.
Bridge: power used at home or netted within the month is worth 12.60¢, Duke’s 14.00¢ average price less its $14 monthly customer charge. Too few Duke Energy Carolinas solar homes are in the reported data, so the share left over at month end is modeled: 60%, credited at 4.53¢. 13,732 × 40% × 12.60¢ + 13,732 × 60% × 4.53¢ = $1,065 a year.
Solar Choice: every kWh at 12.60¢, Duke’s 14.00¢ average price less its customer charge = $1,730 a year. Solar Choice nets by price period, so this is a best case.
Duke’s solar charge on both plans: 9.76 kW × $0.99 × 12 = $115.95. Payback: $26,938 ÷ (savings − $115.95), so 28.4 years on the Bridge and 16.7 years on Solar Choice. No upkeep, rate changes, financing or panel aging.
14.00¢ is Duke Energy Carolinas’ EIA average for the 12 months to August 2026. If Duke’s $22 monthly minimum bill applies every month, the Bridge payback is 31.6 years.
Dominion Energy North Carolina nets kWh for kWh: for a system sized to your use, every kWh is worth 12.37¢, its 13.48¢ average price less its $14.40 customer charge, so $1,698 a year and 15.9 years.
Duke Energy Progress: power used at home or netted is worth 15.05¢, its 16.38¢ average price for the 12 months to August 2026 less its $14 customer charge; leftover power earns 3.94¢ and its solar charge is $1.16 per kW a month ($135.86 a year). Bridge: 13,732 × 40% × 15.05¢ + 13,732 × 60% × 3.94¢ = $1,151 a year, so 26.5 years (21.6 to 32.4). Solar Choice, every kWh at 15.05¢ (a best case): $2,067 a year, so at least 14.0 years.
Duke Carolinas, Duke Progress, Dominion or a co-op: what each pays for leftover power
The name at the top of your bill sets the credit for solar power you do not use yourself. Duke runs two separate utilities in North Carolina, with different numbers.
Duke Energy Carolinas or Duke Energy Progress
4.53¢ or 3.94¢ per leftover kWh
Carolinas serves the Charlotte, Greensboro, Winston-Salem and Durham areas. Progress serves the Raleigh, Wilmington and Asheville areas. Solar charge: $0.99 or $1.16 per kW a month.
Next: ask which Duke utility and which plan the quote uses.
Dominion Energy North Carolina
kWh for kWh
Northeastern North Carolina. Extra kWh roll over to the next month. Unused credit goes back to zero, unpaid, at the start of each summer billing season.
Next: size the system to your yearly use, not the roof.
A co-op or a city utility
Its own rules
The state does not make co-ops offer net metering. Each co-op and city utility writes its own rules. The table below shows four of them.
Next: get the credit and any monthly charge in writing.

Size limits, the minimum bill and leases
Duke limits a home system to 20 kW AC or the home’s estimated highest monthly demand, whichever is less. EnergyUnited allows up to 25 kW on its per-kWh credit, for a system you own. Fayetteville PWC’s credit is for systems of 10 kW or less, and PWC does not allow leased solar in its area.
Duke’s minimum bill covers only customer and delivery costs. Credits for leftover power are taken off after it is applied. Homes in Duke’s low-income energy assistance programs with systems of 8 kW DC or less are exempt.

How we got these numbers
9.76 kW is the typical North Carolina system in our Cost Index, calibrated from Berkeley Lab’s 2025 median of 9.88 kW (5,650 systems). Size yours to the power you use each month.
Output uses the Cost Index figure of 1,407 kWh per kW a year. Shade lowers it.
Duke caps a home system at 20 kW AC, or lower if your home’s highest monthly demand is lower.
A system you own gets no federal tax credit after December 31, 2025.
Duke’s PowerPair rebate: up to $9,000, only with a battery
PowerPair is Duke’s cash rebate for North Carolina home solar paired with a battery. Duke pays it once, for new panels and a home battery installed together. On September 24, 2026, its room was nearly gone.
$3,600Solar part, at most
$0.36 per watt AC on up to 10 kW AC.

Of 30,000 kW on September 24, 2026, and only for homes on Solar Choice.
FullDuke Energy Progress
No room on September 24, 2026. Duke keeps a waitlist.
Example: a system with 7 kW of AC size earns $2,520 for the solar part. With a 13.5 kWh battery the total is $7,920. Room changes every week, so check Duke’s PowerPair page on the day you sign. Our payback cases leave PowerPair and the battery out.
PowerPair rules to check before you sign
You must own the home. The panels and battery can be bought or leased.
Your installer must be a Duke Trade Ally, and the battery must be on Duke’s list.
Apply before the install, or within 90 days after it.
The contract runs 10 years. Leave early and you owe part of the money back, unless you sell the home.
You keep your billing plan for 24 months. On Solar Choice you cannot join Duke’s battery control credit in those 24 months.
Battery control pays a monthly credit when Duke may use your battery 30 to 36 times a year: $52 a month, or $624 a year, for a Tesla Powerwall 3.
North Carolina’s 80% property tax break, and no solar tax credit
North Carolina has no state rebate or tax credit for home solar. What it offers is a property tax exclusion you file for once.

How the 80% exclusion works
Example: if the county values your system at $20,000, then $16,000 is left out and $4,000 is taxed. It is not automatic, and you file once, for the first tax year the system is on your home. Ask your assessor whether it treats a home battery as part of the system or as separate property.
Monthly usePower that cancels kWh you buy that month saves your full price. The leftover earns 4.53¢ or less, so size to your monthly use.

North Carolina Solar FAQs
Does North Carolina have net metering?
Yes, but the credit for leftover power is small for new Duke homes. Power you send out first cancels power you buy in the same month. What is left over is credited at 4.53¢ in Duke Energy Carolinas and 3.94¢ in Duke Energy Progress, and that credit keeps reducing later bills, with no yearly reset. Dominion, co-ops and city utilities set their own rules.
What date counts for Duke’s Net Metering Bridge?
The day a valid interconnection request is filed. Duke takes new Bridge requests until December 31, 2026, while that year’s room lasts. A home that gets in keeps the plan for up to 15 years from that request. Later homes go on Residential Solar Choice.
What happens to Duke solar homes from before October 2023?
They keep Duke’s older net metering rider only until December 31, 2026. By January 1, 2027 they move to the Bridge or another newer plan, which adds a monthly solar charge and a minimum bill.
Is there a North Carolina solar tax credit?
No. North Carolina’s renewable energy tax credit was repealed for systems switched on from January 1, 2016. The federal credit ended for systems you own placed in service after December 31, 2025.
Will solar raise my property tax in North Carolina?
Only a little, if you apply. State law leaves 80% of a solar electric system’s appraised value out of your property tax. File Form AV-10 once with your county assessor, during the listing period that runs through January 31 unless your county extends it.
Can my HOA block solar panels in North Carolina?
Not fully. State law (G.S. 22B-20) voids deed rules that ban solar on a home. An association may still bar panels that can be seen from the ground on the side of the house that faces a street or a shared area. Ask for the rules in writing.
