A new interactive map created by M.I.T. researchers and the city shows how much local families could save by installing solar power systems.
The D.C. Solar Tool shows where solar systems have already been installed, their annual output and about how much residents save. One building near Eastern Market, for example, has had a system since 2013 and helps the owners save an estimated $588 a year on energy costs.
In addition to showing where the systems already exist, the tool created with the D.C. Department of the Environment shows what kind of investment can produce what savings. It’s all searchable by address.
“With just a few clicks, the D.C. Solar Tool shows District of Columbia residents, businesses, and property owners how much electricity can be produced on their rooftops from solar photovoltaic systems, how the financial investment will pay off and how much pollution will be reduced,” the website says.
The data takes into account rooftop shape, weather, shade and vegetation.
The D.C. Solar Tool is part of the District’s push for increased solar energy use. Mayor Vincent Gray set out for 2.5 percent of the District’s power to be solar by 2023. Free installation of solar panels are available now to low-income residents.
