Everything Ohio homeowners need to know: costs, incentives, net metering policy, and what makes this state unique for solar.
Quick answer
Ohio solar economics depend mainly on 4.2 average peak sun hours, an estimated $2.9/W installed cost, 13.0¢/kWh electricity, and the state's current net-metering rules.

Key fact about Ohio solar
Ohio's 2023 SB 221 weakened net metering, reducing export values for new installations. Self-consumption and battery storage are increasingly important for Ohio solar owners.

Ohio Net Metering Policy
Net metering (SB 221 — limited)
Ohio's net metering rules were weakened by SB 221 (2023). AEP Ohio and FirstEnergy now offer net billing rather than full retail NEM for new customers. Export credits are significantly below retail.
Ohio Solar Incentives
Available in addition to any utility rebates. Federal 25D credit is $0 for homeowner-owned systems from 2026.
- ✓Property tax exemption on added home value
- ✓Sales tax exemption
- ✓Ohio Air Quality Development Authority loans

State-specific decision guide
What to verify before signing a Ohio solar quote
In Ohio, the financial result depends on more than sunshine or the headline installation price. Confirm the export rule, program eligibility date, and interconnection timeline for your exact utility before treating a payback estimate as a promise.
Export value
This page models net metering (sb 221 — limited). Ask which tariff and export credit apply to your account, not only which program name appears in the proposal.
Incentive eligibility
Check equipment, income, installer, application, and placed-in-service rules before subtracting an incentive from the quote. Programs can close or change terms.
Interconnection
Budget for the published 5–10 weeks and confirm who pays for a required meter, service upgrade, or engineering review.
Source trail: production assumptions use NREL PVWatts; incentive discovery should be checked against DSIRE; electricity-market context is available from the EIA. Confirm final tax treatment with the IRS and your utility.
