Ohio County Keeps Renewables Ban: What Homeowners Can Do

On May 6, a resident-led ballot campaign in Ohio's Knox County fell short of overturning the county's ban on utility-scale wind and solar. The vote leaves intact a restricted-area designation under Ohio Senate Bill 52 (2021), which lets county commissioners block large renewable projects before they reach the state siting board.

If you live in Ohio — or any state with similar local-control rules — the headline can feel discouraging. But there's a critical distinction worth understanding: county-level bans on utility-scale projects almost never apply to rooftop systems on your own home. Here's the math on what's still possible.

What the Knox County vote actually changed

SB 52, signed in 2021, gave Ohio counties the authority to designate "restricted areas" where wind and solar farms over 50 megawatts cannot be built. As of early 2026, the Ohio Power Siting Board reports that 26 of Ohio's 88 counties have used SB 52 to block at least one renewable project. The Knox County vote was an attempt to rescind that designation. It failed.

The result: utility-scale developers can't easily build large arrays in those counties. But the law is explicit — it covers projects over 50 MW. A typical home rooftop system is 7 to 10 kilowatts (0.007 to 0.010 MW). You are roughly five thousand times below the threshold.

The homeowner math hasn't changed

Ohio's residential electric rates have climbed steadily. According to EIA data, the state's average residential rate hit 16.4¢/kWh in early 2026, up from 12.8¢ in 2020 — a 28% increase in five years. AEP Ohio and Duke Energy Ohio customers are paying closer to 18¢ once distribution and transmission riders are included.

Here's what that looks like for a typical Ohio home using 11,000 kWh/year (slightly above the U.S. average of 10,500 per EIA):

• Annual electric bill at 17¢/kWh: ~$1,870
• 8 kW rooftop system production (NREL PVWatts, central Ohio): ~10,400 kWh/year
• Coverage of household use: ~94%
• Annual bill offset: ~$1,760

That's the gross savings number before incentives, financing costs, and net metering rules. NREL's PVWatts is the standard production calculator behind most reputable estimates — including the one EnergyScout uses.

What about the federal tax credit?

This is where 2026 gets specific. The 30% federal Investment Tax Credit (ITC) for purchased residential solar expired at the end of 2025 for systems homeowners buy outright. Per the IRS guidance on the Residential Clean Energy Credit, only systems placed in service by December 31, 2025 qualified for the residential 30% credit.

Third-party owned systems — solar leases and power purchase agreements (PPAs) — can still claim the commercial ITC under Section 48E because the panels are owned by the financing company, not you. That credit is typically passed through to the homeowner as a lower lease payment or PPA rate.

If you're an Ohio homeowner exploring solar in 2026, the practical takeaways are:

1. Cash purchase: No federal credit, but you own the system. Payback typically 10–13 years at current Ohio rates.
2. Solar loan: Same — no federal credit available. Watch interest rates closely; loan APRs above 8% can erase savings.
3. Lease or PPA: The installer captures the commercial ITC and (in theory) passes savings through. Compare the all-in $/kWh rate to your utility rate.

Net metering in Ohio: the rule that actually matters

For rooftop solar economics, what your county thinks about utility-scale projects is mostly irrelevant. What matters is net metering — how the utility credits you for excess solar exported to the grid.

Ohio's net metering rules, governed by the Public Utilities Commission of Ohio, currently credit residential solar exports at the generation portion of the retail rate (roughly 6–8¢/kWh, not the full 17¢ retail rate). That's less generous than California's pre-NEM 3.0 system but better than the avoided-cost rates seen in some Southern states.

The implication: self-consumption matters more than export. A battery that lets you store afternoon solar production for evening use will outperform a panel-only system in Ohio's net metering environment. Lawrence Berkeley Lab's Tracking the Sun 2024 report found that battery attachment rates on new residential solar nationally have climbed from 10% in 2020 to 35% in 2024, driven largely by changes to net metering in states like California, Arizona, and Hawaii.

Battery storage: the hedge against policy shifts

A 13.5 kWh home battery (the size of a Tesla Powerwall 3 or Enphase 5P stack) covers roughly 24–36 hours of essential loads — refrigerator, lights, internet, furnace fan, and a few outlets. According to SEIA's solar+storage tracker, installed costs for residential storage averaged $1,150/kWh in Q4 2025, down from $1,400 in 2022.

For an Ohio homeowner, the storage value comes from three places:

• Backup during outages: AEP Ohio averaged 4.2 hours of customer outage time in 2024 (per the company's annual reliability report). A battery turns those hours into a non-event.
• Self-consumption arbitrage: Storing solar at low export credits (~7¢) and using it to offset retail purchases (~17¢) recovers the gap.
• Future rate changes: If Ohio shifts to time-of-use rates (as several utilities are now piloting), batteries become significantly more valuable.

The local picture: installers still active in Ohio

Despite the utility-scale headlines, Ohio's residential solar market grew 18% in 2024 according to SEIA's state-by-state data. There are roughly 280 active residential installers statewide, concentrated around Columbus, Cleveland, Cincinnati, and Toledo. Quote spreads are wide — EnergyScout data from 2025 showed $2.85 to $4.10 per watt for cash purchases on identical 8 kW systems in central Ohio. That's a $10,000 difference on a single project.

Bottom line

The Knox County vote is a reminder that local energy politics are messy and don't always reflect the underlying economics. For Ohio homeowners, the relevant questions in 2026 are simpler:

• What's your actual utility rate (including riders), and what's the trend?
• How much of your bill can a 7–10 kW rooftop system realistically offset?
• Does a battery make sense given Ohio's net metering credits?
• What does an honest cash, loan, lease, and PPA comparison look like for your home?

Those are answerable with real numbers — your roof's solar potential (NREL data), your utility's actual rates (your bill), and your household's load profile.

Local control over utility-scale projects doesn't change the math on your roof.
