Utility rules and programs for Hamilton
City of Hamilton and Duke Energy Ohio serve Butler County, so which rules apply depends on your address.
| Utility | Type | Solar export rule |
|---|---|---|
| City of Hamilton | city-owned | Hamilton runs its own city electric utility; we did not verify its net metering terms, so ask the city. |
| Duke Energy Ohio Inc | investor-owned | Duke Energy Ohio says net metering needs an approved interconnection agreement. If you buy from a competitive supplier, the supplier may offer a net metering contract; if not, Duke compensates your excess generation. We could not read the credit rate, so ask Duke. |
Program details are from each utility’s own pages (read October 2026). See the Ohio incentives table for statewide credits and a status for every program.

Solar Panel Installation in Hamilton FAQs
Is solar worth it in Hamilton?
The sun is strong (about 1,160 kWh a year per kW, our estimate), but export credits are low, so solar pays most when sized to what you use at home or paired with a battery. See the Ohio incentives for the state credit.
Is there a federal solar tax credit in 2026?
No. The federal 25D credit ended for expenditures after December 31, 2025. We found no Ohio state solar credit; the state sales-tax and property-tax treatment of home solar is not confirmed, so ask your installer.
Do I need a permit for solar panels in Hamilton?
Usually yes, and the utility may need to approve solar and batteries. City of Hamilton Permits (Butler County also serves the area) handles permits in Hamilton; see the permit information above.
