Durham is a split utility market: most of the city sits in Duke Energy Carolinas territory, while eastern parts of Durham County fall in Duke Energy Progress, so confirm which one serves your exact address before you size a system, because your net-metering rider follows it. Permits go through Durham City-County Inspections, and North Carolina power runs about 15.09 cents per kWh, so strong Carolina sun does the heavy lifting.
Durham is a strong rooftop solar market: plenty of Carolina sun, a deep local installer base around the Triangle, and a joint city-county permitting office that handles solar as a routine accessory use. What trips Durham homeowners up is not the sun, it is the money math, and one detail that is genuinely different from Raleigh. Durham is a split utility market. Most of the city is served by Duke Energy Carolinas, the old Duke Power system, while eastern parts of Durham County sit in Duke Energy Progress, and the operating company decides your net-metering rider and your battery-rebate eligibility. On top of that, Duke retired full-retail net metering for new solar in 2023 and the federal homeowner tax credit ended after 2025. This page lays out what solar actually costs in Durham in 2026, how to tell which Duke utility serves you, how the City-County office permits a system, and which incentives are still live. Every figure here is dated and linked to its source. For the statewide picture, start with our North Carolina solar guide. Updated for 2026.
What solar costs in Durham in 2026
North Carolina’s power prices sit below the national average, which is the honest starting point. At about 15.09 cents per kWh for residential customers (EIA Electric Power Monthly, Table 5.6.A, data for May 2026; national average about 18.4 cents), the bill solar offsets in Durham is smaller than in the high-rate Northeast. What tips the math in Durham’s favor is sunshine: the Triangle gets strong solar resource, so a right-sized system produces a lot of kilowatt-hours per dollar of panel.
According to MySolarFY’s analysis (August 2026), a typical 6 kW system in Durham (ZIP 27701) produces about 8,236 kWh a year (modeled with NREL’s PVWatts calculator, v8, standard assumptions). That works out to roughly 1,373 kWh per installed kW each year, a strong specific yield, which at North Carolina’s current 15.09 cents per kWh trims about $104 off a typical monthly power bill. Your own output depends on roof pitch, orientation, and shade from Durham’s tall oaks and pines, so treat this as a planning estimate and run your own address through PVWatts for a tighter number. For the full cost-per-watt and payback breakdown by system size, see our North Carolina solar cost and payback guide.
Which Duke utility serves your Durham home?
This is the Durham-specific step, and it is the one to get right first. Unlike Raleigh, which sits cleanly in Duke Energy Progress territory, Durham straddles a service boundary. The city of Durham is served largely by Duke Energy Carolinas, the former Duke Power footprint, while eastern parts of Durham County fall in Duke Energy Progress (Durham Economic Development lists Duke Energy Progress for the county, while customer-count data shows Duke Energy Carolinas as the largest provider inside the city). Because the two operating companies file their own tariffs, your net-metering rider and your PowerPair battery-rebate eligibility follow whichever one serves your exact address. Check the operating company printed on your Duke bill, or confirm it with Duke before you plan.
Worth knowing: Duke has asked regulators to merge Duke Energy Carolinas and Duke Energy Progress into a single utility, filed in August 2025 with a target effective date of January 1, 2027, still pending approval from the North Carolina Utilities Commission and other regulators (ABC11). Duke says there is no immediate change to retail rates, but the split that makes Durham’s answer depend on your address would eventually simplify. Verify the current status before you rely on it.
Net metering in Durham: the Duke riders
The big change: full-retail 1:1 net metering is gone for new solar customers. Duke Energy’s legacy Rider NM, which credited every exported kilowatt-hour at the full retail rate, closed to new residential solar on September 30, 2023 (DSIRE, North Carolina net metering). That closure applies across both Duke operating companies, so it holds whether your Durham address is on Duke Energy Carolinas or Duke Energy Progress. New customers now choose between two Duke riders, and the one you pick decides what your exports are worth. Verify the current terms and any capacity limits with Duke before you sign.
| Duke rider (new Durham solar) | How it credits you | The catch to verify |
|---|---|---|
| Rider NMB (Net Metering Bridge) | Simple monthly netting, no time-of-use requirement, a set stay period | A transitional option that is capacity-capped and time-limited, so confirm it is still open on your operating company |
| Rider RSC (Residential Solar Choice) | Time-of-use pricing with critical peak periods; exports credited near Duke’s avoided-cost rate, not full retail | Adds a minimum monthly bill and non-bypassable charges, so shifting usage to off-peak matters |
| Source | DSIRE, North Carolina net metering; confirm current tariff terms with Duke Energy | |
What this means for a Durham homeowner: the bridge rate (Rider NMB) is the friendlier option because it keeps simple monthly netting, while Residential Solar Choice (Rider RSC) shifts you to time-of-use and credits exports below retail. Because the bridge rider is capacity-limited and time-bound, its availability on your specific operating company is exactly the kind of thing to verify before you commit. Either way, sizing a system to your own usage matters more than it used to, since over-exporting no longer earns full retail. To see how the credit works in detail, read how net metering credits your solar exports, and for how the bridge rate and time-of-use exports compare across Duke’s operating companies, see our North Carolina net metering guide for 2026. For the full Duke breakdown, including interconnection and the PowerPair battery rebate, see our Duke Energy North Carolina solar guide.
Durham solar incentives in 2026 (including Duke PowerPair)
North Carolina does not run an SREC market or a state income-tax credit, so a Durham incentive stack is shorter than Maryland’s or New Jersey’s. What it does have is a strong property-tax exemption and a Duke solar-plus-battery rebate. Here is what is live in 2026, with one detail that turns on which Duke utility serves your address.
| Incentive | What it pays | 2026 status for Durham to verify |
|---|---|---|
| Duke PowerPair (solar + battery) | A one-time incentive of up to $9,000 for pairing home solar with a battery (about $0.36 per watt of solar and $400 per kWh of battery) | Capped and split by operating company. The Duke Energy Carolinas side that serves most of Durham reached roughly full enrollment in mid-2026 and moved new applicants to a waitlist, and the Duke Energy Progress side is also fully allocated. Confirm current availability for your operating company |
| Property-tax exemption | Excludes 80% of a residential solar system’s value from property tax | A standing North Carolina law; your added home value in Durham County is largely shielded from higher property taxes |
| State income-tax credit | None for homeowners | North Carolina’s old 35% credit expired for systems placed in service after December 31, 2015; there is no current state credit |
| Federal residential (Section 25D) | A 30% homeowner credit | Ended for expenditures made after December 31, 2025; a 2026 buyer cannot claim it |
The Durham-specific catch is Duke PowerPair. Duke’s PowerPair pilot pays a one-time incentive of up to $9,000 to homeowners who install solar together with a battery (DSIRE, Duke Energy PowerPair). It is a capped pilot split between the two operating companies, and this is where knowing your utility matters: the Duke Energy Carolinas territory that serves most of Durham drew down its remaining capacity through the first half of 2026 and moved new applicants to a waitlist, while the Duke Energy Progress side is also fully allocated. Because that status moves, confirm current PowerPair availability for your specific operating company before you count on it. For a full breakdown of every North Carolina incentive, see our North Carolina solar incentives 2026 guide.
The property-tax exemption is the durable one. North Carolina excludes 80% of a residential solar electric system’s value from your property-tax assessment, so adding panels does not swing your Durham County tax bill the way a home addition would (DSIRE, North Carolina property-tax abatement). North Carolina’s sales-tax treatment of residential solar equipment has shifted over the years, so verify the current rule with the North Carolina Department of Revenue rather than assuming an exemption. And North Carolina has no general residential solar income-tax credit today, since the old 35% state credit expired after 2015.
Heads up on the federal credit: the 30% federal Residential Clean Energy Credit (Section 25D) ended for expenditures made after December 31, 2025, so a Durham homeowner buying with cash or a loan in 2026 cannot claim it (IRS). A separate commercial credit (Section 48E) can apply to leased and PPA systems, but the company that owns the panels claims it, not you. Always confirm your own situation with a licensed tax professional. MySolarFY does not provide tax advice.

Submitted securely and used to match you with licensed installers in your area. Some homeowners may qualify for no-up-front-cost lease or PPA options where available. A lease or PPA can carry an annual price escalator and, over its full term, may cost more than owning the system with cash or a loan. On a lease or PPA the provider owns the panels and keeps any tax benefits, and the 30% federal credit ended after December 31, 2025. Not a savings guarantee.
Permitting solar in Durham
Durham runs a joint city and county building office, so your solar permit goes through Durham City-County Inspections, not a Raleigh-style same-day city portal. Since October 1, 2019, every residential and commercial solar PV system in Durham requires a building permit, and applications, electrical plans, and one-line diagrams are submitted through the department’s online plan-review portal (City of Durham, Solar Panels). Your installer typically pulls the permit for you and submits the plan set and equipment specs.
A few Durham specifics worth knowing before you sign:
- Who files it: a licensed installer normally handles the City-County building permit and the Duke interconnection application. Confirm both are in your contract, and that the interconnection goes to the correct operating company for your address.
- Zoning and setback: Durham allows solar as an accessory use in all zoning districts, and residential panels must sit at least six feet from property lines, though they may encroach into a required yard.
- Inspections: a small rooftop solar project typically needs only two inspections, scheduled through the department’s online tools after the permit is issued.
- Timing: a Durham permit expires if no inspections happen within six months, so line up your installer before you pull it.
Because rules can change, verify current requirements on the City of Durham solar permitting page and confirm interconnection steps with Duke. To pressure-test any installer’s numbers, use the right questions to ask a solar installer.
Is solar worth it in Durham?
For many Durham homeowners, yes, but the case rests on production, a routine permit, and the property-tax break more than on a rich incentive stack. With below-average power prices, the payback here is driven by strong Carolina sun, a system sized to your own use under Duke’s newer riders, and keeping your added home value out of your Durham County property-tax bill. If you own the system through cash or a loan, you keep those benefits directly; if you lease or sign a PPA, the company that owns the panels keeps any tax benefits while you get a lower or fixed power price with no up-front cost. For a full payback walkthrough, see the financial case for whether solar panels are worth it, and for the broader picture, browse our solar by state guides.
How to choose a Durham installer: screen any company against objective criteria rather than a “best” list. Look for NABCEP certification, a valid North Carolina electrical license, a written workmanship and equipment warranty, real local experience with Durham City-County permitting and Duke interconnection paperwork, and a clear production estimate you can compare. MySolarFY matches you with licensed installers that serve the Durham area so you can compare real local quotes side by side, with no obligation. Keep in mind the 30% federal Residential Clean Energy Credit ended for expenditures made after December 31, 2025, so a 2026 cash or loan buyer cannot claim it; for the full timeline, read what the federal solar tax credit change means for homeowners. Sizing up your options next to nearby Raleigh solar can also help, since Raleigh’s cleaner single-utility setup makes a useful contrast.
Frequently asked questions
Which utility serves Durham for solar? It depends on your address, and that is the Durham-specific catch. Most of the city of Durham is served by Duke Energy Carolinas, the former Duke Power system, while eastern parts of Durham County fall in Duke Energy Progress. Your net-metering rider and your PowerPair eligibility follow whichever operating company serves you, so check the name on your Duke bill or confirm with Duke before planning. Duke has also asked regulators to merge the two companies, with a target date of January 1, 2027, still pending approval.
How do I get a solar permit in Durham? Solar permits in Durham go through Durham City-County Inspections, the joint city and county building office. Since October 1, 2019, every residential solar PV system needs a building permit, submitted with electrical plans and a one-line diagram through the department’s online plan-review portal. A small rooftop project typically needs only two inspections, and the permit expires if no inspection happens within six months. Your installer usually handles the filing. Verify current requirements on the City of Durham solar page.
Is net metering still available in Durham? Yes, but not the old full-retail version for new customers. Duke Energy’s legacy 1:1 net metering (Rider NM) closed to new residential solar on September 30, 2023, across both Duke operating companies. New Durham customers choose between Rider NMB, a transitional bridge option with simple monthly netting, and Rider RSC (Residential Solar Choice), a time-of-use rate that credits exports near Duke’s avoided-cost rate rather than full retail and adds a minimum monthly bill. Because the bridge option is capacity-capped, verify current availability with Duke.
Is Duke PowerPair still open for Durham homes? Verify it for your operating company. PowerPair is a Duke Energy pilot that pays a one-time incentive of up to $9,000 to homeowners who install solar paired with a battery, roughly $0.36 per watt of solar and $400 per kWh of battery. It is capped and split by operating company: the Duke Energy Carolinas side that serves most of Durham drew down its capacity through the first half of 2026 and moved new applicants to a waitlist, and the Duke Energy Progress side is also fully allocated. Confirm current status before planning around it.
How much does solar produce in Durham? Production depends on your roof, but as a benchmark MySolarFY’s analysis (August 2026) models a typical 6 kW system at ZIP 27701 at about 8,236 kWh a year using NREL’s PVWatts calculator, roughly 1,373 kWh per installed kW. At North Carolina’s current 15.09 cents per kWh that offsets about $104 off a typical monthly bill. Roof pitch, orientation, and shade from Durham’s tall oaks and pines all move that number, so run your own address through PVWatts for a tighter estimate.
Does Durham or North Carolina have a state solar tax credit? No. North Carolina’s 35% state solar tax credit expired for systems placed in service after December 31, 2015, and there is no general residential state solar income-tax credit today. The durable tax benefit for a Durham homeowner is the property-tax exemption, which excludes 80% of the system’s value from your Durham County property-tax assessment. The federal Residential Clean Energy Credit (Section 25D) separately ended after December 31, 2025.
