Transforming industries by reimagining the possible.

Our Featured Project


Hanwha Solutions’ Qcells is one of the world’s largest and most recognized photovoltaic (PV) manufacturers, known for its high-quality solar cells and modules.


Qcells selected Gray to design and build its first U.S. manufacturing operation. After the construction of an award-winning manufacturing facility, the customer selected Gray for a large project at the same campus to expand production and storage capacity.


Most recently, Qcells chose Gray to lead a monumental third project—the construction of the largest solar panel production plant in the U.S., in Cartersville, GA.

Gray provides specialized global services for customers across six core markets. View past and current projects here.
