A mixed-use development in Decatur has installed a nearly $900,000 solar array � one of the largest commercial rooftop systems in metro Atlanta.

The 147 kilowatt East Decatur Station installation is capable of powering more than 15 homes, said James Marlow, CEO of Radiance Solar, an Atlanta-based solar engineering, procurement and construction firm that developed the project.

East Decatur Station, located on New Street, is a collection of buildings that include restaurants and offices.

Made up of three different arrays, the East Decatur Station system produces 198,134 kWh of energy annually and is expected to offset the development’s energy cost by up to 20 precent, Marlow said.

The Georgia Environmental Finance Authority provided East Decatur Station with a grant for the photovoltaic installation through the Clean Energy Property Rebate Program.

Established in 2009 as a result of the American Recovery and Reinvestment Act (ARRA), the Clean Energy Property Rebate Program offsets up to 35 percent of the cost of installing renewable energy property, implementing lighting retrofits or building efficiency upgrades, subject to a maximum cap that varies depending on the technology installed.

East Decatur Station qualifies for an additional 30 federal grant.
