What the adoption figure means
A thin market. Fewer installers cover it, quotes take longer to assemble, and comparison is harder simply because there is less to compare.
Residential electricity in Ohio averaged 15.99¢ per kilowatt-hour in 2024, 18th of 51 and below the national average of 16.48¢. Retail prices sit above the national middle, which tilts the arithmetic toward using production on site rather than exporting it. Prices and adoption across all 51.
System size and consumption
The average Ohio system was 7.44 kW in 2024, ranking 24th of 51. Households consumed an average of 10,146 kilowatt-hours a year (30th of 51) — the figure a system here is sized against.
Size your own system from your own kilowatt-hours, not from this average — how to do that.
Who owns the systems
3.8% of Ohio systems were third-party owned in 2024 — leased or under a power purchase agreement rather than owned by the householder. That is 23rd of 51.
Third-party ownership is common, so leases and PPAs will be presented alongside purchase. Who claims the federal credit · ownership across all 51.
Battery attachment
5.98% of Ohio solar systems were paired with a battery in 2024, 8th of 51 — 1,647 paired systems.
Attachment is well above average, so storage is a normal part of a quote here rather than an upsell. Attachment across all 51 · does a battery belong in your project.
Where the market is going
Ohio added 5,113 systems in 2024 and has grown at 30.5% a year over five years, 16th of 51. Where growth has turned.

Method
Figures are computed by HyreSolar from the Form EIA-861 2024 annual files — net-metered residential systems only, penetration counted against residential accounts, sizes as means. EIA publishes the inputs, not these ratios. Full methodology and the underlying CSV.

Common questions
How many homes in Ohio have solar?
27,520 residential net-metered systems were recorded in Ohio in 2024, against 5,142,108 residential electricity accounts — 0.54% of households, 40th of 51 jurisdictions. That is a HyreSolar calculation from Form EIA-861.
What size solar system is typical in Ohio?
The average net-metered residential system in Ohio was 7.44 kW in 2024, against a national average of 6.74 kW. Your own system should be sized from twelve months of your kilowatt-hours and your usable roof, not from a state average.
Do people in Ohio add batteries to solar?
5.98% of Ohio systems were paired with storage in 2024, 8th of 51. Battery attachment tracks outage frequency and export rules more than it tracks sunshine.
Is Ohio a good state for solar?
On the measures we can compute: residential electricity averages 15.99¢/kWh (18th of 51), households use 10,146 kWh a year (30th of 51), and 0.54% have installed a system (40th of 51). Retail price and export rules move the answer far more than sunshine does, and both are set by your specific utility rather than by the state.
