Home Depot gets DC’s biggest rooftop solar installation

WASHINGTON — The Home Depot store at 901 Rhode Island Avenue in Northeast D.C. now claims the title of having the largest single rooftop solar array in the District.

The solar array, a joint project between Constellation, General Electric and Home Depot, includes more than 1,400 photovoltaic panels and is expected to supply more than 9.9 million kilowatt-hours of electricity to Home Depot through the 15-year contract period.

Home Depot said it will generate enough electricity to cover 35 to 40 percent of the store’s annual energy use.

Home Depot will purchase the electricity generated by the system through a power purchase agreement with Constellation.

GE’s Solar Development division designed the project, led the construction and will be responsible for operations and maintenance during the 15-year contract period.

“As the leading home improvement retailer, The Home Depot is proud to host the largest single rooftop solar project in the District,” said Craig D’Arcy, director of energy management for Home Depot.

The project at Home Depot’s Brentwood store is the first of several Constellation-owned, GE-developed rooftop arrays for Home Depot on additional stores in Prince George’s and Montgomery Counties by the end of 2018.

Exelon, which acquired Pepco in 2016, owns Constellation.
