Ohio homeowners evaluating solar in 2026 often start by asking about a state tax credit — and while Ohio doesn't offer one, the Ohio solar incentives 2026 picture is more comprehensive than that single data point suggests. The complete package — strong property and sales tax protections, utility incentive programs, federal commercial credits, and statewide net metering at retail rates — adds up to a compelling return on investment for Ohio homeowners and business owners alike. Here is every program available, with current 2026 data.
Federal Investment Tax Credit — 2026 Status
The federal solar tax credit is the most-asked-about incentive for any state, and Ohio is no exception. The current status in 2026:
- Section 25D Residential ITC — Expired: The 30% residential tax credit for homeowners expired on December 31, 2025. Homeowners who completed installations before that date were eligible for the full 30% credit. New residential installations in 2026 are not eligible for the Section 25D credit.
- Section 48E Commercial ITC — Active at 30%: The commercial Investment Tax Credit remains active through 2027. Ohio business owners, farmers, landlords, and self-employed individuals installing solar on qualifying commercial or mixed-use properties can claim 30% of the full installed system cost as a federal tax credit. On a $45,000 commercial installation, that's $13,500 in direct federal tax reduction.
For Ohio homeowners purchasing residential systems in 2026, the focus shifts to state exemptions, utility programs, and net metering savings — all of which remain robust.
Ohio Property Tax Exemption
Ohio provides one of the cleanest property tax protections for solar in the Midwest. Under Ohio Revised Code § 5709.53, solar energy conversion equipment is 100% exempt from real property taxation. When you install solar panels in Ohio, your county assessor is prohibited from increasing your property's assessed value based on the solar system.
For the typical Ohio homeowner, a solar installation that adds $20,000–$30,000 in market value to the home generates zero additional property tax burden. With Ohio's average effective property tax rate of approximately 1.36% — one of the higher rates in the Midwest — this exemption is genuinely valuable. Over 25 years, it can represent $6,800–$10,200 in cumulative tax savings on a $20,000–$30,000 value addition.
Ohio Sales Tax Exemption
Ohio exempts solar energy equipment from the state's 5.75% sales tax under Ohio Revised Code § 5739.02. Most Ohio counties add 0.75%–2.25% in local sales tax, bringing combined rates to 6.5%–8%. The full combined rate is typically waived on qualified solar equipment purchases.
On a $25,000 residential system, even a conservative 7% combined rate represents $1,750 in immediate savings. This exemption applies automatically at the point of sale with a qualifying solar contractor — no separate application required.
Utility Incentive Programs: AEP Ohio & Duke Energy
Ohio's two largest investor-owned utilities — AEP Ohio and Duke Energy Ohio — have operated solar incentive and energy efficiency programs for residential customers. Current 2026 status:
- AEP Ohio: AEP Ohio has offered Renewable Energy Credits and solar incentive programs tied to Ohio's renewable portfolio standards. Homeowners in AEP service territory (Columbus area and eastern/central Ohio) should have current program availability confirmed — Legacy Energy checks AEP's current program slate for every project in their territory.
- Duke Energy Ohio: Duke Energy Ohio serves the Cincinnati metropolitan area and surrounding southwest Ohio counties. Duke has maintained energy efficiency and renewable incentive programs and periodically opens solar-specific rebate windows. Legacy Energy monitors Duke's current offerings and handles all customer applications.
- Ohio Edison / FirstEnergy: Serves northeast Ohio including Cleveland, Akron, and Youngstown. FirstEnergy subsidiaries have operated various demand-side management programs; check current availability through your installer.
- Dayton Power & Light (AES Ohio): Serves the Dayton region. Periodically offers rebate programs for residential solar and energy efficiency upgrades.
Net Metering in Ohio
Ohio law requires utilities to offer net metering to residential and commercial solar customers at the full retail electricity rate. This is codified under Ohio Revised Code § 4928.67, which mandates net metering for systems up to 25 kW for residential customers.
Ohio's average residential electricity rate of approximately $0.13/kWh — combined with an average of 4.3 peak sun hours per day — means a properly sized Ohio solar system can offset 85–100% of annual household electricity consumption. Full retail net metering makes every excess kilowatt-hour worth exactly what you'd otherwise pay for it.
Ohio homeowners benefit from a virtual "solar bank" — excess production during sunny midday hours is credited against consumption at night and on cloudy days, at equal value. This eliminates the concern many homeowners have about cloud cover: your production peaks offset your evening consumption at dollar-for-dollar value.
| Incentive | Value | Status |
|---|---|---|
| Federal Residential ITC (Section 25D) | 30% | Expired Dec 31, 2025 |
| Federal Commercial ITC (Section 48E) | 30% | Active through 2027 |
| Property Tax Exemption | 100% (ORC § 5709.53) | Active — permanent |
| Sales Tax Exemption | 100% (ORC § 5739.02) | Active — permanent |
| AEP Ohio / Duke Energy Programs | Varies | Confirm current availability |
| Net Metering Rate | Full retail (~$0.13/kWh) | Required by state law |
Ohio Solar Financial Snapshot
Here's how the numbers look for a representative Ohio residential installation in 2026:
- Avg. system size: 8–10 kW
- Avg. installed cost: $22,000–$30,000
- Sales tax savings: ~$1,500–$2,100
- Annual property tax savings: ~$270–$408/year (at 1.36% rate)
- Annual electricity savings: $900–$1,200/year at $0.13/kWh
- Typical residential payback period: 7–9 years
- 25-year net savings: $18,000–$35,000+ after system cost
Ohio's 7–9 year payback period is competitive with the national average, and the 25-year savings projection is driven primarily by net metering credits and electricity price escalation over time.
Maximizing Your Ohio Solar Incentives in 2026
- Start with a no-cost site assessment. Legacy Energy's certified engineers evaluate your roof, utility, shading, and consumption data — and identify every incentive you qualify for, including current utility programs in your specific service territory.
- Confirm utility rebate availability before signing any contract. AEP, Duke, and other Ohio utilities periodically open and close rebate windows. Starting your project before confirming incentive availability is a common and avoidable mistake.
- Own your system — don't lease it. Leases and PPAs transfer the tax and financial benefits to the financing company. With ownership (cash or loan), every incentive dollar stays with you.
- Business owners: prioritize the Section 48E credit. If you own or operate a business in Ohio, the 30% commercial ITC remains one of the strongest available incentives in the country — and it disappears after 2027.
- Right-size your system for your consumption. Oversized systems generate excess credits your utility may not carry forward indefinitely. Legacy Energy designs to your actual annual kWh consumption for maximum financial efficiency.

Ohio's solar market continues to grow because the underlying economics are solid. With property and sales tax exemptions that produce permanent, compounding savings, retail-rate net metering that monetizes every kilowatt-hour your system produces, and utility programs that add additional upfront value, the 7–9 year residential payback timeline is well within reach for most Ohio homeowners. Legacy Energy's job is to make sure you don't leave any of those incentives on the table.
