Challenge

This nine-story building is located off a busy avenue in NW D.C. with a ballasted roof.

Solution

NCS installed 285 Recom 335 panels and SolarEdge inverters on top of the ballasted gravel covered membrane. Due to increased wind on rooftops for buildings of this heights, NCS installed wind deflectors to distribute and reduce loading on the roof. Under the terms of the deal, this multifamily building will receive low-cost energy for the next 15 years, benefiting both building owners and residents.

“NCS has been a pleasure to work with through the solar installation process. The work had zero impact on our management time. They took care of everything. There was nothing for me to do as building manager. The impact on top floor residents was minimal. They let us know in advance when they would be on the roof, and they respected our request that no work be done before 9:00 AM.”
