Solar Alliance completed the design, engineering and installation of the 526-kilowatt (kW) roof mount solar system for AESSEAL, Inc., a specialist in the design and manufacture of mechanical seals and support systems. The system was installed at AESSEAL’s North American headquarters in Rockford, Tennessee. Soon, a large portion of the assembly, quality control, engineering and customer service operations at this facility will be running on power from the sun. The array supports AESSEAL Inc.’s Net Zero efforts. This is one of the largest commercial solar installations in the region.
