Rebates and incentives, Ohio
A confirmed property tax exemption, a genuinely disputed sales tax exemption, below-retail net metering, and a modest SREC market. See your numbers, with the disputed pieces flagged honestly.
How it works
Step 1
Sources genuinely disagree on whether Ohio's sales tax exemption applies to a residential solar purchase. Ask your installer to confirm in writing whether tax is charged on your invoice, since this can be a $1,000 or more swing on a typical system. Check the sales tax exemption savings calculator once you know.
Step 2
Ohio Revised Code Section 5709.53(B) exempts systems up to 250 kW from real property tax on the added value, which is confirmed directly from the statute text. Some sources report this applies automatically through the permit record, but practices vary by county, so a quick check with your local auditor's office is worthwhile.
Step 3
Since Ohio's net metering typically pays less than retail for any remaining balance at the end of the annual true-up, a system sized closer to your household consumption tends to capture more value than one built for large export. Check your federal ITC status too, since it affects your overall budget alongside these state-level pieces.
Ohio Revised Code Section 5709.53(B) exempts any energy facility with a nameplate capacity of 250 kilowatts or less, a threshold that covers essentially every residential solar system, from real property taxation on the value the system adds, for installations completed on or after January 1, 2010. This is confirmed by reading the statute text directly, which makes it more reliable than several guides that incorrectly claim Ohio offers no property tax exemption at all. Some sources describe the exemption as self-executing through the county auditor's permit record, without a separate homeowner-filed form, though this can vary by county, so confirming with your local auditor is still a reasonable step. Use the property tax exemption savings calculator to estimate the ongoing value.
This is one of the more contested points across solar guides for any state, and we're not going to manufacture false confidence about it. Several sources cite Ohio Revised Code Section 5739.02(B)(32) as a residential solar sales tax exemption. However, at least one detailed source reports contacting the Ohio Department of Taxation directly and being told no such residential exemption exists, and the sales tax exemption language that does appear prominently in the statute, section 5739.02(B)(40), is written for property sold to an electricity provider generating or distributing power for others, which reads more like a utility-scale provision than a homeowner one. Given this direct conflict between sources, and between at least one plain statutory reading and how the exemption is commonly described, don't assume either way. This is a separate question from net metering, which is covered below and has its own open questions. Ask your installer for written confirmation of whether sales tax is charged on your specific invoice, and run the numbers both ways with the sales tax exemption savings calculator.
Ohio requires investor-owned utilities including AEP Ohio, FirstEnergy, and Duke Energy Ohio to offer net metering under PUCO rules, and excess generation credits roll forward month to month within an annual billing period. Multiple sources describe the rate applied to any remaining credit balance at the end of that annual period as commonly below the full retail rate, in some cases at the utility's avoided cost, rather than a straightforward 1:1 retail credit throughout. This makes Ohio's net metering meaningfully less generous than states with full retail crediting, and it argues for sizing your system closer to your own household usage rather than for large surplus export. There's also an active fight worth tracking: as part of PUCO's ongoing five-year review of the state's net metering rules, AEP has formally proposed adding distribution charges to all electricity flowing through a solar household's meter, even power that's simply passing through on its way back to the grid. PUCO staff has recommended keeping the current rules in place and rejecting AEP's proposal, and other Ohio utilities have not joined AEP in pushing for the change, but no final decision had been issued as of this writing.
Ohio's Renewable Portfolio Standard creates demand for solar renewable energy credits, with one SREC generated per megawatt-hour of production. Reported average SREC values have been cited around $3, which works out to roughly $20 to $30 per year for a typical residential system, a modest addition rather than a meaningful income source. That income is also not guaranteed to continue: Ohio's RPS requirements are scheduled to end entirely in 2026, which removes the compliance demand that gives Ohio SRECs any value in the first place, so don't build a long-term financial case around this income stream. Separately, some cities offer their own property tax abatement programs beyond the statewide exemption, with Cincinnati and Cleveland commonly cited as examples, so it's worth checking whether your specific municipality has an additional local program layered on top of the statewide benefit. Your rebate total changes what a loan costs each month, and the combined loan and rebate timing tool shows that payment once you enter both figures.

Questions
Yes, this one is confirmed directly from the statute. Ohio Revised Code Section 5709.53(B) exempts any energy facility with a nameplate capacity of 250 kilowatts or less, which covers virtually every residential system, from real property taxation on the value the system adds, for installations completed on or after January 1, 2010. Several guides incorrectly claim Ohio has no property tax exemption at all, which contradicts the statute's plain text. Some installers report the exemption applies automatically through the county auditor's permit record, though practices can vary by county, so confirming with your local auditor is still worthwhile.
This is genuinely disputed among sources, and we are not going to pretend otherwise. Some guides cite Ohio Revised Code Section 5739.02(B)(32) as a residential solar sales tax exemption. Other sources, including one report that says it confirmed the answer directly with the Ohio Department of Taxation, state that no such residential exemption exists, and the sales tax exemption language that does appear in the statute is written for electricity providers selling power to others, not homeowners installing a system for their own use. Given this conflict, ask your installer for a written answer on whether sales tax applies to your specific purchase before assuming either way.

Modestly, and not indefinitely. Ohio's Renewable Portfolio Standard creates demand for solar renewable energy credits, with one SREC generated per megawatt-hour of solar production. Reported average SREC values in Ohio have been cited around $3, meaning a typical residential system might earn roughly $20 to $30 per year, which is a minor addition rather than a meaningful income source. Ohio's RPS requirements are also scheduled to end entirely in 2026, which removes the compliance demand underlying this market, so don't count on this income stream continuing long-term. SREC prices fluctuate with supply and demand, so treat any specific figure as an estimate rather than a guarantee.
