- Your wires utility is Duke Energy Ohio. In Cincinnati and Hamilton County the regulated distribution utility that delivers your power and runs interconnection is Duke Energy Ohio, part of Duke Energy but a separate PUCO-regulated company from Duke in the Carolinas and Florida (Duke Energy Ohio, as of 2026).
- Ohio power costs about 19.5 cents per kWh. Ohio’s average residential price is roughly 19.5 cents per kWh (EIA Electric Power Monthly, Table 5.6.A, May 2026), so each kilowatt-hour your roof makes offsets one you would otherwise buy.
- Ohio has electric choice, so you pick your generation supplier. The generation part of your bill is deregulated: you can shop a PUCO-certified supplier or take Duke’s standard service offer, while Duke Energy Ohio still delivers the power and handles your net metering (Energy Choice Ohio, as of 2026).
- Net-metering exports are credited at a generation-only rate, not full retail. Verify the current figure, but Ohio credits the power you export at an unbundled generation rate rather than the full delivered retail rate, so on-site use is worth more than export (DSIRE Ohio net metering, as of 2026).
- Ohio’s SREC market is weak, so do not count on it. Verify the current price before you budget anything; Ohio’s renewable standard was rolled back and SREC values have been low and illiquid (DSIRE Ohio renewable standard, as of 2026).
- The 30% federal homeowner credit (Section 25D) ended after December 31, 2025 (IRS, as of 2026), so a Cincinnati homeowner who buys solar in 2026 with cash or a loan cannot claim it.
Cincinnati sits in Duke Energy Ohio territory, and that one fact shapes how rooftop solar pays you back here. Ohio is a deregulated electricity state, so you choose who generates your power while Duke delivers it and runs your net metering. This page covers what solar really involves in Cincinnati in 2026: who your utility is, what Ohio’s rates and net-metering rules mean for your bill, how Cincinnati permitting works, and what changed federally, so you can decide with real local numbers instead of a generic pitch.
Why Cincinnati electric rates make solar worth a look
The reason solar pays is the price of the power it replaces. Ohio’s average residential electricity price is about 19.5 cents per kWh (EIA Electric Power Monthly, Table 5.6.A, May 2026), close to the national average and above where Ohio sat a few years ago. In a deregulated market your bill has two parts: the generation price, which you can shop, and Duke Energy Ohio’s delivery charges, which are regulated and fixed no matter who supplies your power. Every kilowatt-hour your roof makes and you use on-site offsets the full delivered price, generation plus delivery, which is why on-site use is the most valuable kilowatt-hour solar produces. For the statewide picture, see our Ohio solar guide and the Ohio solar cost breakdown.
Using NREL PVWatts for a Cincinnati ZIP (45202), a typical 7 kW rooftop system is modeled to produce about 8,748 kWh a year. At Ohio’s average residential price of 19.5 cents per kWh (EIA, May 2026), that output is worth roughly $1,710 of grid power a year when used on-site. This is a MySolarFY calculation from NREL PVWatts production and the EIA rate, not a quote or a savings guarantee; your roof, shading, usage, and how you pay all change the real number (PVWatts, EIA, as of August 2026).
Your actual production is what turns that rate into savings. Cincinnati gets a solar resource typical of the Ohio Valley, and output depends on your roof’s pitch, shading, and orientation, so estimate your specific roof with NREL’s free PVWatts calculator rather than a generic number before you size a system.

Who is your electric utility, and why deregulation matters
In Cincinnati your regulated wires utility is Duke Energy Ohio. It delivers your electricity, owns the poles and meters, runs the interconnection process for rooftop solar, and administers your net metering (Duke Energy Ohio, as of 2026). It is worth being precise here: this is Duke Energy Ohio, a separate PUCO-regulated company from Duke Energy’s utilities in North Carolina, South Carolina, and Florida, so guidance written for a Duke customer in Charlotte or Orlando does not apply to a net-metering question in Cincinnati.
Because Ohio is deregulated, generation and delivery are two different things. Ohio has electric choice, which means you can shop the generation portion of your bill from a PUCO-certified competitive supplier, or simply take Duke’s standard service offer if you do not shop (Energy Choice Ohio, as of 2026). Either way, Duke Energy Ohio still delivers the power and handles your net metering. This split matters for solar because your export credit is tied to a generation rate, not the full delivered price, which is the single most important local detail on this page.
How Duke Energy Ohio credits the power your roof sends back
On-site use is worth the full retail price; exports are credited at a lower, generation-only rate. When your panels make power and you use it in the house, you avoid the full delivered price of that kilowatt-hour, generation plus delivery. When your panels make more than you are using and the extra flows to the grid, Ohio credits that export at an unbundled generation rate rather than the full retail rate (DSIRE Ohio net metering, as of 2026). The exact credit rate comes from Duke Energy Ohio’s PUCO-filed tariff and, if you shop, your supplier’s contract, so verify the current figure before you size a system. For how export crediting works in general, see how net metering credits your solar exports.
The practical takeaway is to size for self-consumption. Because exports are worth less than on-site use here, the smart move in Cincinnati is to size a system close to your own usage and shift more of your consumption into daylight hours, rather than oversizing to push a lot of cheap power onto the grid. A battery can help you use more of what you make, though it adds cost, so weigh it against your own load. To see how the bill credit lowers your monthly cost, read how solar lowers your electricity bill.
| Where the solar kWh goes | What it is worth to you |
|---|---|
| Used on-site in your home | The full delivered retail price, generation plus Duke delivery charges, the most valuable kilowatt-hour |
| Exported to the grid | Credited at a generation-only, unbundled rate, below full retail; verify current terms with Duke’s tariff |
| Ohio SRECs | A market exists but is weak and illiquid; verify the current value and treat it as a bonus, not a plan |
Solar permitting in Cincinnati and Hamilton County
Inside the city, your solar project runs through the City of Cincinnati Department of Buildings. A building permit is required before any solar work begins, rooftop or ground-mounted, followed by the electrical permit and inspection (City of Cincinnati Department of Buildings, as of 2026). A licensed installer normally files the permit package, coordinates the inspections, and manages Duke Energy Ohio’s interconnection application and the final permission to operate, which is the sign-off you need before you can legally switch the system on.
If your home is in an unincorporated part of Hamilton County or in a separate municipality outside Cincinnati city limits, the permit authority may be the county or that local building department instead, so confirm which office covers your address before you start. For the questions that surface a solid local installer, see the right questions to ask a solar installer.
Paying for solar in Cincinnati: cash, loan, lease, or PPA
There is no single right way to pay for solar; the best fit depends on whether you want to own the system and keep any tax and incentive benefits yourself, or avoid an up-front cost. A lease or PPA can mean no up-front cost for eligible homeowners, but it is a long-term agreement with monthly payments, not free solar, and the company that owns the panels keeps the incentives. To weigh the long-run numbers, see whether solar panels are worth it, and for how the money side works, our guide to paying for solar.
| Path | Up-front cost | Who owns the system | Best when |
|---|---|---|---|
| Cash purchase | Full system cost | You | You want the fastest payback and the most lifetime savings |
| Solar loan | Little to none, financed | You | You want ownership without paying cash up front |
| Lease or PPA | $0-up-front where eligible | The third-party owner | You prefer no up-front cost and a simpler, fixed monthly bill |
What changed federally, and what it means for Cincinnati
The federal homeowner credit is gone, but Ohio’s rates and net metering are not. The 30% federal Residential Clean Energy Credit (Section 25D) ended for expenditures made after December 31, 2025, under the One Big Beautiful Bill Act, so a Cincinnati homeowner who buys solar in 2026 with cash or a loan cannot claim it (IRS, as of 2026). A separate commercial credit, Section 48E, can apply to leased and PPA systems, but the business that owns the system claims it, not the homeowner. Ohio net metering and your bill savings from on-site use were not affected. For the full timeline, see what the federal solar tax credit change means in 2026.
How to choose a solar installer in Cincinnati
Greater Cincinnati has an active market of licensed installers, which is good for you because it means real competition on price and service. Rather than chasing a “best installer” list, screen any company against objective criteria:
- NABCEP certification, the industry’s professional standard for PV installers.
- Proper Ohio licensing and the required Cincinnati building and electrical permits.
- A clear workmanship and equipment warranty in writing.
- Real experience with Duke Energy Ohio interconnection and City of Cincinnati permitting, so the paperwork and permission to operate go smoothly.
- A written production estimate and a transparent quote that is honest about the generation-only export credit and does not lean on Ohio SREC income. For a checklist, see the right questions to ask a solar installer.
MySolarFY matches you with licensed installers that serve your area so you can compare real local quotes side by side, with no obligation.

Frequently asked questions
Who is my electric utility for solar in Cincinnati?
Your regulated wires utility is Duke Energy Ohio, the PUCO-regulated distribution company that serves Cincinnati and Hamilton County, delivers your power, and administers net metering (Duke Energy Ohio, as of 2026). It is a separate company from Duke Energy’s utilities in the Carolinas and Florida, so net-metering guidance for those states does not apply here. Because Ohio is deregulated, you can also shop your generation supply from a PUCO-certified supplier, but Duke still delivers the power and handles your solar interconnection.
How does net metering work in Cincinnati?
Power you make and use on-site offsets the full delivered retail price, generation plus Duke’s delivery charges, which is the most valuable kilowatt-hour your system produces. Power you export to the grid is credited at an unbundled, generation-only rate rather than full retail (DSIRE Ohio net metering, as of 2026). Verify the current credit rate in Duke Energy Ohio’s PUCO tariff, because it is a generation rate, not the delivered price. The practical result is to size a system close to your own usage rather than oversizing it for exports.
Are Ohio SRECs worth anything for a Cincinnati homeowner?
An Ohio SREC market technically exists, but the state’s renewable standard was rolled back and SREC prices have been low and illiquid, so treat any SREC income as a small bonus at most, not a reason to buy (DSIRE Ohio renewable standard, as of 2026). Verify the current price with a broker before you count on any figure, and ask any installer to model your payback on bill savings alone, not on SREC revenue.
Is there still a federal tax credit for solar in 2026?
Not for homeowners who buy. The 30% federal Residential Clean Energy Credit (Section 25D) ended for expenditures made after December 31, 2025, under the One Big Beautiful Bill Act, so a Cincinnati homeowner who buys solar in 2026 with cash or a loan cannot claim it (IRS, as of 2026). A separate commercial credit, Section 48E, can apply to leased and PPA systems, but the business that owns the system claims it, not the homeowner.
Do I need a permit for rooftop solar in Cincinnati?
Yes. Inside the city, a building permit from the City of Cincinnati Department of Buildings is required before any solar work begins, followed by an electrical permit and inspection (City of Cincinnati Department of Buildings, as of 2026). A licensed installer usually files the permits, coordinates inspections, and manages Duke Energy Ohio’s interconnection and final permission to operate. If your home is outside city limits in unincorporated Hamilton County or another municipality, confirm which building department covers your address.
Is solar worth it in Cincinnati in 2026?
It depends on your roof, your usage, and how you pay, but the local case rests on offsetting Ohio power at about 19.5 cents per kWh (EIA, May 2026) with on-site solar, since exports are credited at a lower generation-only rate. A MySolarFY estimate using NREL PVWatts for a Cincinnati ZIP puts a 7 kW system near 8,748 kWh a year, worth roughly $1,710 of grid power when used on-site (as of August 2026). Savings are not guaranteed and the federal 25D credit is gone, so compare a couple of local quotes and size for self-consumption before deciding.
Reviewed by the MySolarFY team. Figures were verified against the linked Duke Energy Ohio, PUCO / Energy Choice Ohio, DSIRE, EIA, NREL PVWatts, and IRS sources as of August 2026; the net-metering export rate, Ohio SREC prices, and utility tariffs move over time, so confirm current terms with Duke Energy Ohio and the PUCO before you decide.
