Greentech Renewables and RER Energy Group teamed up last year to develop a solar array for Domino Sugars in Baltimore, MD. The office building, with its iconic electric sign playing a prominent role in the Baltimore skyline, is now powered by clean, renewable energy provided by the 35kW rooftop array.

SMA inverters were chosen due to the world class reputation of SMA as well as the cutting edge features of the Sunny Tripower series. The two transformerless 15000TL-US units used in the array boast a peak efficiency above 98 percent, while OptiTrac Global Peak minimizes the effects of shade for maximum energy production.

The AET Rayport ballast mount configuration underwent a host of changes and was complicated by the unique structural demands of the roof. Throughout the entire process, AET provided steadfast customer support and invaluable engineering expertise.
“This project has been a very difficult design and posed many challenges and we were very grateful for the partnership we have with Greentech Renewables,” states RER Energy GM Loretta Ottinger.
Ranked by Solar Power World as one of the largest solar contractors in the US, RER Energy Group has developed more than 20 Megawatts (MW) of solar arrays at over 75 business, school and municipal facilities. RER currently serves clients in Delaware, Maryland, New Jersey, New York and Pennsylvania.
