DAYTON, Ohio — Walmart is rolling out solar power at a dozen Ohio stores.
The giant retailer has installed solar power arrays atop the stores in a process that's been in the works during the past year. They'll start producing power Monday.
The Dayton Daily News reports that it will increase the state of Ohio's total solar power generation by 10 percent. Wal-Mart says the project makes it the state's largest single solar power user.
The solar panels sit on the rooftops of the stores and are not visible from the ground.
The Walmart and Sam's Clubs that installed the solar power systems are in Mason, Xenia, Greenville, Austintown, Middletown, Franklin, Youngstown, Toledo, Milford, Loveland, and two in Cincinnati.
Walmart says there will be more such installations coming to Ohio.
