Solar in Ohio: is it worth it in 2026?
Ohio is a slow-payback state: solar works, but it takes well over a decade to earn back what you paid. Three things decide that: electricity prices rank 19th of 51, its sun ranks 40th, and exported power earns retail credit within each month, with leftovers paid less. Of the 51 states and DC, Ohio has the 21st-fastest payback for a typical home.
The average home here pays about $148 a month for 874 kWh. A 7.5 kW system sized for that home would knock about $1,544 off the first year's bills, 87% of the total.

What makes solar pay off in Ohio
- Size the system to cover your yearly use. With monthly netting, power you export is worth nearly as much as power you use, so aim for little leftover each month.
- The price per watt decides it. At 16.9¢ per kWh, the price per watt matters as much as the sun. At $3.34 per watt, the high end of what companies quote, payback for a typical system here stretches to 16 years.
Payback by system size
An average Ohio home uses about 10,488 kWh a year. Here's how systems sized to cover part or all of that work out, bought with cash at $2.57 per watt:
| Covers | Size | Price | Makes a year | Payback | 25-year savings |
|---|---|---|---|---|---|
| 49% | 4 kW | $10,280 | 5,184 kWh | 14 years | $13,432 |
| 74% | 6 kW | $15,420 | 7,776 kWh | 13 years | $21,460 |
| 99% | 8 kW | $20,560 | 10,368 kWh | 13 years | $29,488 |
| 124% | 10 kW | $25,700 | 12,960 kWh | 14 years | $30,962 |
The 6 kW system pays back fastest, but the 10 kW system saves the most over 25 years. Assumes exported power earns about 90% of the retail rate, prices rise 2.5% a year and one inverter replacement.
How Ohio credits power you send to the grid
Monthly netting
Exported power offsets your usage at the retail rate; power left over is credited at the lower generation rate. Regulators reaffirmed net metering in January 2026.
We haven't found a single published export rate for Ohio, so the calculators assume about 90% of the retail rate. Ask your utility for its rate and enter it.
By utility
- AEP Ohio: Exported power offsets your usage at the retail rate; power left over is credited at the lower generation rate. Regulators reaffirmed net metering in January 2026.
- FirstEnergy Ohio (Ohio Edison, Illuminating Co., Toledo Edison): Monthly retail netting; surplus is credited at the generation rate, under Ohio's rules reaffirmed in January 2026.
Before you sign in Ohio
Check the license. Look the company up with the Ohio Construction Industry Licensing Board, by its legal name or license number, and ask for the electrician's license number too.
Ohio has no solar-specific sales law that we know of, so its general consumer protection law applies.
In every state, the FTC Cooling-Off Rule lets you cancel a contract signed at your home until midnight of the third business day.

Questions about solar in Ohio
How long does solar take to pay for itself in Ohio?
About 13 years for a typical 7.5 kW system bought with cash at the 2026 median price of $2.57 per watt, with no federal tax credit and one inverter replacement. A bigger or smaller system, a different price, or your own usage will change that; the table above shows other sizes.
Does Ohio have net metering?
Partly. Exported power offsets your usage at the retail rate; power left over is credited at the lower generation rate. Regulators reaffirmed net metering in January 2026.
Is there a solar tax credit in Ohio in 2026?
Not from the federal government for buyers: the 30% homeowner credit ended for systems installed after December 31, 2025. For a typical 7.5 kW system in Ohio, that credit was worth about $5,783 and brought payback down to 9 years, instead of 13 years now. Leasing companies can still claim a business credit, so ask for a lease or PPA price too. Your state energy office lists any state rebates.
Is a solar battery worth it in Ohio?
Not for savings. Ohio credits exported power at close to the retail rate, and storing power in a battery loses about 10% of it, so a battery saves nothing on the bill. It can still be worth it for backup during outages: a 13.5 kWh battery costs about $15,650 installed in 2026.
Is plug-in solar legal in Ohio?
Not yet. A bill (HB 755 / SB 383) is pending: in committee.
How do I check a solar company's license in Ohio?
Look the company up with the Ohio Construction Industry Licensing Board (com.ohio.gov) by its legal name or license number, and ask for the electrician's license too.
