ATAS International had a ribbon cutting ceremony to celebrate the installation of a 620.1 kW photovoltaic (PV) solar electric system that was recently installed on one of ATAS’ plants located on Grant Way in Allentown, Pennsylvania. The 60,000 square foot building was constructed in 2005 and is used by ATAS for manufacturing. The PV system was installed by RER Energy Group (RER) over an existing standing seam metal roof system. It will generate more energy than is used at the building on which it is installed; ATAS will use the excess energy to benefit its other nearby building on Snowdrift Road, which serves as the company headquarters. The solar array cost a little more than $1 million to install, and the estimated payback is two and a half years.
