Ohio's solar situation in 2026 is the definition of "viable but not exciting." The state has 4.0 peak sun hours per day, a modest SREC market, electricity rates averaging $0.142/kWh, and no strong state incentive program. Payback periods run 11–16 years — real but long. For homeowners who plan to stay in their home and want energy price protection, solar still makes sense. It's just not the rapid ROI story you'd see in Arizona or Massachusetts.

Key Takeaways
- A typical 8 kW Ohio system costs ~$22,400 at $2.80/watt (LBNL 2024) — no federal 25D credit applies in 2026
- Ohio SREC prices have been modest (~$5–$15/SREC), providing limited additional incentive compared to Illinois or Maryland
- At $0.142/kWh (EIA 2025) average, Ohio rates are below the national average — extending payback vs. higher-rate states
- Estimated payback: 11–16 years depending on utility and SREC market conditions
Ohio Solar Costs in 2026
At $2.80/watt, Ohio is near the national median for solar installation costs. An 8 kW system — right-sized for a typical Ohio single-family home — costs approximately $22,400 before any incentives. With 4.0 peak sun hours per day, that system produces roughly 11,700 kWh annually.
Ohio's electricity rate of $0.142/kWh is slightly below the national average of $0.161/kWh (EIA 2025). That difference matters: the same production savings $0.142 per kWh in Ohio versus $0.192 in Michigan or $0.171 in Illinois. Lower rates extend payback periods even when sun hours are similar.
| System Size | Cost at $2.80/W | Annual Production (4.0 hrs) | Annual Savings at $0.142/kWh |
|---|---|---|---|
| 6 kW | $16,800 | ~8,760 kWh | ~$1,244 |
| 8 kW | $22,400 | ~11,680 kWh | ~$1,659 |
| 10 kW | $28,000 | ~14,600 kWh | ~$2,073 |
Ohio's SREC Market: Modest but Real
Ohio is part of a multi-state SREC market, and Ohio SRECs (Solar Renewable Energy Credits, 1 SREC = 1 MWh of solar production) can be sold to utilities that must meet renewable portfolio standards. However, Ohio's SREC market has historically been much weaker than neighboring Illinois or mid-Atlantic states like Maryland and New Jersey.
Ohio SREC prices have ranged from approximately $5–$15 per SREC in recent years — far below the $75–$90 values in Illinois or $40–$60 in Maryland. At that price, an 8 kW system producing 11.7 SRECs annually generates only $59–$176/year in SREC revenue. That's real money, but it doesn't dramatically change the payback calculation.
Unlike Illinois's Shines program (which locks in a 15-year contract price), Ohio SREC prices are determined by open market dynamics and can fluctuate significantly. Don't build your financial case around SREC projections — treat any SREC revenue as a bonus, not a core assumption.
Net Metering in Ohio
Ohio's net metering law (Ohio Revised Code Section 4928.67) requires investor-owned utilities to offer net metering for residential solar systems. Ohio's major utilities — AEP Ohio, FirstEnergy (Ohio Edison, Cleveland Electric Illuminating, Toledo Edison), and Duke Energy Ohio — all offer net metering at the full retail rate.
This is a positive for Ohio solar. Full retail net metering at $0.142/kWh means every kWh exported earns the same credit as one kWh consumed. For Ohio homeowners, that's better than states where export rates are degraded (California, Arizona, Nevada). System sizing to roughly 100% of annual consumption is financially sound in Ohio's net metering environment.
What's Missing: No State Solar Credit
Ohio has no state income tax credit for residential solar. The state's solar incentive landscape is thin: no cash rebate programs, no production-based incentives from major utilities, and a weak SREC market. The primary financial framework is:
- Net metering savings at $0.142/kWh retail rate
- SREC revenue (modest, variable)
- Property tax exemption (Ohio Revised Code 5709.53) — solar equipment is exempt from personal property tax, though its application to added home value for real property tax purposes varies by county
According to Lawrence Berkeley National Laboratory's Tracking the Sun 2024 report, states with minimal incentive programs and below-average electricity rates — Ohio's profile — show some of the longest residential payback periods nationally.
The EV + Solar Case in Ohio
Adding an EV meaningfully improves Ohio solar economics. A typical EV adds 3,375–4,500 kWh of annual home charging demand. At Ohio's $0.142/kWh rate, solar covering that EV charging saves $479–$639/year in electricity — plus the gasoline displacement savings (roughly $1,530/year for 13,500 miles in a 30 MPG car at $3.40/gallon).
Combined EV + solar savings can reduce effective Ohio payback periods by 3–5 years. For Ohio homeowners considering an EV, sizing up their solar system to cover charging demand is often the most financially compelling reason to install.

What to Do Next
Confirm your utility and current electricity rate.
AEP Ohio, FirstEnergy, and Duke Energy Ohio all offer net metering but have different rate structures. Your specific rate tier — especially if you’re on a time-of-use rate — affects your solar ROI calculation significantly.
Be honest about your time horizon.
Ohio’s 11–16 year payback requires you to stay in your home through the payback period. Solar panels carry 25-year production warranties — so the economics work over the full system life. But the break-even is later than in many other states.
Factor in your EV or future EV plans.
If you drive or plan to drive an EV, size your system to cover both home electricity and EV charging. The combined savings from electricity and gasoline displacement shorten payback materially compared to solar-only economics.

Bottom Line
Ohio solar in 2026 is viable for long-term homeowners, especially those with EVs. The combination of modest sun, average rates, no state credit, and a weak SREC market means payback runs 11–16 years — real, but slower than higher-incentive states. Full retail net metering and a 25-year panel lifespan mean the return on investment is there — it just takes time. Ohio residents planning to stay in their homes long-term and looking for rate protection have a reasonable case for solar.
