Solar power in Ohio has been increasing, as the cost of photovoltaics has decreased. Ohio installed 10 MW of solar in 2015. Ohio adopted a net metering rule which allows any customer generating up to 25 kW to use net metering, with the kilowatt hour surplus rolled over each month, and paid by the utility once a year at the generation rate upon request. For hospitals there is no limit on size, but two meters are required, one for generation, the other for utility supplied power.
In 2010, the 12 MW solar farm in Upper Sandusky, Ohio was the largest solar farm in the state. It was later surpassed by the 20MW DG AMP Solar Bowling Green, which was completed in January 2017.
The First Solar factory in Perrysburg, Ohio can make almost 600 MW of panels per years.
Costs have decreased to the point that the average consumer may save approximately $17,527 over a 20-year period by installing solar panels. Euclid's City Hall and library installed solar panels and expects to save $25,000 over the next 15 years. The panels were installed at no cost to the city by Ohio Cooperative Solar, which is leasing the rooftops.
When you install a solar system, 26% of your project expenses apply toward a credit to offset any taxes you owe that year. This federal tax credit is a major incentive to go solar, but it is going to be phased out by 2024.
To be eligible to claim this credit, you must owe federal taxes.
