Ohio solar and battery property tax exemption open

Administered by county auditors, under section 5709.53 of the Ohio Revised Code.

Solar panels and, since 14 August 2025, batteries on an Ohio home are exempt from real property tax, if the system is 250 kW or smaller and was installed on or after 1 January 2010. It is a state incentive that rebate sites miss.

What it pays

No published cap — and that is the honest answer

An exemption, not a payment: the system's fixtures are left out of the property's taxable value, so the saving depends on your local tax rate.

size
An aggregate nameplate capacity of 250 kW AC or less; a home system is far below that.
installed
On or after 1 January 2010.
batteries
Energy storage systems count as part of an energy facility from 14 August 2025, under House Bill 15.

Who is eligible

ownership
The law defines an energy facility as equipment owned by the same person; it does not address systems leased or owned by a third party.
procedure
The statute sets out no application. Ask your county auditor how the exemption is recorded.

The thing most pages get wrong

Rebate sites say Ohio has no state solar incentive. Section 5709.53(B) of the Revised Code exempts the fixtures of any energy facility of 250 kW or less installed since 2010 from real property tax, and House Bill 15 added energy storage systems to what counts from 14 August 2025.

The federal credit is gone

Cincinnati's solar page still calls the federal Residential Clean Energy Credit one of the most significant ways to cut the cost of home solar. It ended for systems installed after 31 December 2025.
