Constellation Energy to Build Largest U.S. Solar Rooftop Project

Constellation Energy Group Inc., which agreed to be bought by Exelon Corp., is building the largest U.S. rooftop solar-energy project, at a Toys “R” Us Inc. distribution center in New Jersey.

Constellation will use 37,000 solar panels from Energy Conversion Devices Inc. for the 5.38-megawatt project, Paramus, New Jersey-based Toys “R” Us said today in a statement. The system is expected to meet about 72 percent of the Flanders center’s power needs.

The rooftop system would be the largest at a single building when complete, overtaking SunPower Corp.’s 4.8-megawatt array that’s being built on top of Glimcher Realty Trust’s Jersey Gardens mall, according to the Solar Energy Industry Association.
