Solar in Ohio: the three numbers that decide it

Sun hours. Ohio averages 4.5 peak sun hours a day (NREL), rank 41 of 51. After typical system losses that is about 1,314 kWh per installed kilowatt per year.

Electricity price. Residential power costs about 18.8¢/kWh (EIA, 2026), rank 18 of 51 — the higher the rate, the more each solar kilowatt-hour is worth.

Installed cost. Around $2.80 per watt before incentives (EnergySage marketplace data, 2026). With no federal credit for 2026 installs, this is the price you actually pay for an owned system.

Put together, a household with a $150 monthly bill would size a ~7.3 kW array, pay about $20,424, save roughly $1,800 in the first year and reach payback in about 11.3 yrs. Use the calculator above with your own bill.

Frequently asked questions

How much do solar panels cost in Ohio?
Installed cost in Ohio averages about $2.80 per watt before incentives (2026). A system sized for a $150/mo bill — roughly 7.3 kW — comes to about $20,424. Get quotes from several licensed installers; local pricing and equipment choices move the figure.
Is solar worth it in Ohio?
For a $150/mo bill, the estimate is $1,800 saved in year one and $45,203 net over 25 years after paying $20,424 for the system, with payback in about 11.3 yrs. Higher bills and good roof orientation shorten payback; shading and low net-metering export rates lengthen it.
Is there a federal solar tax credit in Ohio for 2026?
No. The 30% federal residential solar credit (IRC §25D) was repealed for costs paid after December 31, 2025, and that applies in every state. State and utility incentives in Ohio are not included in this estimate and can still improve the payback — check the state energy office.
How many sun hours does Ohio get?
About 4.5 peak sun hours per day on average (NREL data), ranking 41 of 51 states and DC. Each installed kilowatt therefore produces roughly 1,314 kWh a year after typical system losses.
Why does the electricity rate matter?
Ohio's residential rate is about 18.8¢/kWh (EIA, 2026), ranking 18 of 51. Savings scale directly with the rate: every kWh your panels produce replaces a kWh you would have bought at that price.
