"People in Ohio think it doesn't work here because there are too many overcast days," he said.
First Solar, a major manufacturer, has a factory in Perrysburg. All of the equipment made there is sold in Germany, which typically enjoys fewer sunny days than the Buckeye State, he said.
The Ohio Solar tour is intended to make more people aware solar energy's potential.
"It's important for people to see that this stuff really works," Spratley said.
Government-sponsored incentives and the rising cost of fossil fuels are attracting more businesses to venture into alternative energy systems, he said.
"It's still expensive, but for the first time since 1985 we have tax credits available," he said.
State grants also exist.
The Ohio Department of Development's Energy Office offers grants of up to $25,000 to help homeowners pay the cost of solar systems.
The grants are offered on a first-come, first-served basis, said Sherry Hubbard, energy outreach manager for the state office. The amount is based on $3.50 per watt produced by the solar energy system. Homeowners must be served by investor-owned utilities such as American Electric Power.
"Solar energy is not a panacea," Spratley said. "It's not a silver bullet. But we need a more acceptable mix of a variety of energy sources in the future.
"Solar should be a bigger part of the mix."
