Solar panels in at Doraville police station

An Atlanta firm recently installed 72 solar panels at the Doraville police station, designed to conserve both money and energy.

A $65,000 federal grant paid for the panels, which will generate 22,222 kilowatt-hours of energy. The system is expected to save the city $5,000 a year in utility costs.

The solar panels also will reduce carbon dioxide emissions equal to nearly three cards, 12,800 gallons of water and 4 acres of trees.
