ATAS International Captures the Sun’s Power in Mesa, Arizona
In a continuing effort to improve energy efficiency at their facilities, a 187.2 kW photovoltaic (PV) solar electric system was recently installed on ATAS International’s plant located in Mesa, Arizona. The PV system was installed by RER Energy Group (RER) over an existing metal trapezoidal seam roof system.
Dick Bus, President of ATAS, stated the array will offset a substantial amount of ATAS’ annual electric usage, representing an important accomplishment in ongoing environmental and sustainability efforts. “We initially were going to install a system in Pennsylvania but decided to do the smaller Arizona installation first. It is producing electricity better than anticipated and we are moving forward with installing a 500 kW roof mounted array at our Grant Way facility in Allentown, Pennsylvania,” stated Bus.
According to Loretta Ottinger, the sales representative for RER Energy Group, the system consists of 576 roof-mounted, photovoltaic solar panels of 325 watts each. The array will produce more than 297,900 kWh (kilowatt hour) of renewable energy annually, resulting in energy cost savings in excess of $1.5 million over the life of the system. The system is expected to pay for itself within four years and three months. It made sense to focus on ATAS’ Arizona facility first, for a solar system installation; the Solar Energy Industries Association (SEIA) reported in June of 2018 that the state of Arizona is ranked third in the nation for the amount of solar installed, up from being ranked seventh in the prior year. A total of 3,463.4 MW has been installed in Arizona, resulting in 6.09% of the state’s electricity produced from solar. ATAS is proud to now be part of that solar growth in Arizona.
Solar installations continue to increase throughout the country. In May of this year, California regulators approved a historic plan to mandate rooftop solar panels on most new single-family homes built in the state. The California Energy Commission's solar mandate, which goes into effect in 2020, received the support of homebuilder and solar trade associations as well as several large utilities. Currently, the SEIA reports that California leads the nation in solar installations, followed by North Carolina.
Metal roofing is the ideal platform on which to attach solar arrays, due to its long service life. Metal Construction Association (MCA) studies have proven that standing seam metal roofing systems can last 60 years or longer in most environments with proper installation. Crystalline solar panels typically have a life expectancy of 25-30 years, so the metal roofing system will surely outlast the solar panels. Installing solar panels on a roofing system with a lifespan of less than 30 years creates a situation where building owners may not get the full value from their solar panels. They could end up removing working solar panels to repair or recover a failing roofing system. Crystalline solar panels can be easily attached to standing seam metal roofing using specially designed clamps, without any roof penetrations. S-5! manufactures and rigorously tests a variety of these metal roof attachment systems, and they were used on this ATAS facility in Arizona.
As a manufacturer of metal roofing, ATAS wanted to set an example on their own facility to show how solar and metal roofs can work together, resulting in a long-lasting, sustainable, and energy efficient system. Solar ready metal roofing is the best solution for any building on which solar is being considered.
