Ohio's HB 755 would legalize plug-in solar. At last report the bill was in committee. Ohio's legislature meets year-round in a two-year session, so it remains alive.

Ohio rates are slightly above the national average, and the state's large stock of older single-family rentals makes it a natural market.

What plug-in solar is worth in Ohio

Ohio households pay an average of 19.45¢ per kWh, 6% above the US average of 18.31¢. With roughly 4 peak sun hours a day, here is what a well-placed system produces and saves. We assume panels facing south at about 30°, 86% system efficiency and 80% of output used on-site.

Plug-in systems aren't net-metered: surplus sent to the grid earns nothing. ~80% is typical without a battery; 95%+ with one.

What to do now

  1. 1Don't connect a grid-tied plug-in system yet — without a law, it may breach your utility agreement.
  2. 2Consider an off-grid setup in the meantime: a panel charging a portable power station is legal everywhere.
  3. 3Cut your bill today with no-cost measures — see our guide to lowering your electric bill.
  4. 4Contact your Ohio state legislators: constituent support is what moved the 2026 bills.

Ohio plug-in solar FAQ

Is plug-in solar legal in Ohio?

Not yet. A plug-in solar bill is moving through the legislature. Without a law, connecting a grid-tied plug-in system may violate your utility's interconnection rules. Off-grid setups (a panel charging a portable power station) are allowed everywhere.

How much can balcony solar save in Ohio?

At Ohio's average residential rate of 19.45¢/kWh (EIA, July 2026) and about 4 peak sun hours a day, a south-facing, tilted 800 W kit saves roughly $156 a year, paying back a $900 kit in about 5.8 years. Vertical railing mounts produce about 30% less.

What is the maximum plug-in solar size in Ohio?

There is no Ohio-specific cap yet. Most state laws settle on 1,200 W, the practical limit for a standard 15-amp, 120 V circuit.
