The Top 10 Counties in Ohio for Solar Energy

Solar for Homeowners | 8 min read
Top solar energy counties in Ohio

Ohio may not be the first or second place that comes to mind when thinking about great places to install solar energy. It’s not known as the sunniest state, particularly up north, due to moisture coming off the Great Lakes. 

But despite the cloudy weather, solar energy is alive and well in the Buckeye State. 

As installation costs continue to decrease, and electricity rates from utility companies continue to increase, an investment in solar energy is becoming more and more profitable for Ohio businesses, farmers, and homeowners alike. 

In this blog, we’re breaking down the top ten counties in Ohio for solar. Spread across the state from north to south, you’ll see how solar energy can be a great investment regardless of the weather. 

How We Calculated the Rankings

To create our Top 10, we looked at two factors for solar in each county: the total amount of megawatts (MW) of solar installed, and the number of solar energy systems installed. Each of Ohio’s 88 counties were then assigned a number from 1 to 88 based on how they ranked compared to other counties. We then averaged those two rankings, coming up with the overall score. 

It’s important to us that the list isn't skewed by the counties that have the largest utility-scale solar farms. That’s why we weighted the overall number of installations proportionately to the overall MW of installed solar. The number of installations is a better indicator of how easy local municipalities and utility companies makes it for its businesses and homeowners to go solar. So if there was a tie between two counties, the county with the higher number of installations installed is our winner.

1. Cuyahoga County, OH

11.27 MW (#9 in Ohio) | 153 Installations (#3 in Ohio)

Why Is Cuyahoga County Good for Solar?

Home to Cleveland, the birthplace of former U.S. President James A. Garfield, and the northernmost section of Cuyahoga National Park, Cuyahoga County has so much to offer. Included in this is the fact that it comes in as the best county for solar energy in Ohio.

Though it doesn’t take the top spot in either MW installed or overall installations, its combination suggests it’s a great place to install solar, leading all other countries with 83.5 out of 88 possible points.

While their overall MW production is just 11.27 MW, they boast 153 independent installations, meaning that power is coming from homes, businesses, and farms—not large, utility-scale solar farms.

In March 2021, Kent State University's College of Podiatric Medicine in Independence, energized a 315.2 kW ground mount solar system

Comprised of 788 solar panels, this system will produce 350,000 kWh a year - 27% of the electric usage at this campus. That's enough to power 42 homes and is equal to removing 52 cars from the road. 

2. Hamilton County, OH

7.76 MW (#11 in Ohio) | 279 Installations (#1 in Ohio)

Why Is Hamilton County Good for Solar?

Hamilton County may not have the highest solar MW nameplate rating, but they do have the most solar systems installed. That was enough to make them #2 on our list of best counties in Ohio to install solar. Their overall score is 83, which puts them in a tie with Franklin County, but because they had more systems installed, Hamilton County is the winner.

The overall number of systems installed is an important ranking factor, because it means independent businesses, farmers, and homeowners are encouraged to install their own solar systems. While these systems may be smaller than utility-scale solar systems, they have a positive economic impact on the people living in that county through continued savings.
