Broadening solar’s scope & impact

How DSD helped The Home Depot significantly expand its rooftop solar energy program across 37 locations throughout the east coast.


The Challenge

When The Home Depot decided to expand its renewable energy program — as part of its ambitious corporate climate initiative — the bar was set high. Leadership aimed to broaden solar energy usage across the east coast: starting with 27 installations across store locations in New Jersey, Connecticut, Maryland and Washington, DC.

DSD’s rooftop arrays are just one part of The Home Depot’s ever-expanding ESG goals.

The Execution

Prepping and designing solar arrays for 27 locations required a comprehensive and detailed cross-team effort. But in the process, DSD identified opportunities for improvement within existing sites’ infrastructure, which enabled numerous highly impactful operational upgrades.

DSD gathered data on local grid interaction and onsite plant production — as well as detailed weather tracking sensor data — which would prove critical to optimizing long-term energy usage across locations. Through that due diligence, DSD was also able to offer a unique financing solution that delivered additional value.

The Solution


The Home Depot expanded the project from 27 to 37 stores — reducing electricity grid demand by 30-35% across all retail locations.

The Outcome

Once the solar arrays were up in 27 stores, The Home Depot expanded the project to include an additional ten stores. The completed 15.5 MW portfolio has delivered an immediately impact — reducing electricity grid demand by an estimated 30 to 35 percent annually across all 37 retail locations.

The Impact

“DSD evolved our operations efforts with a beautiful solution — designed specifically for our needs — that dramatically lowered our energy costs and reduced our carbon emissions.”
