The Musical Instrument Museum (MIM) in Phoenix, Arizona, is newly sporting the PowerPly PV solar system, courtesy of Lumeta. The MIM project is the first U.S. commercial installation of the roof-integrated PowerPly PV module, which, along with the cells that go in the module, is manufactured by Suntech Power Holdings.
“We are delighted to partner with MIM on this PowerPly installation. PowerPly attaches directly to the roof membrane eliminating the need for roof penetrations or heavy ballasting, typical of conventional systems,” said Jonathan Pickering, general manager of Lumeta. “We were able to complete the installation in less than half the time required for a conventional system, minimizing disruption to the museum.”
Bill DeWalt, president and director of MIM, noted that the PowerPly module not only allows for the museum to cut its energy costs, but also maintain an aesthetically pleasing rooftop appearance.
“The Lumeta PowerPly solar technology that we selected for our roof will most likely reduce our energy costs by 15% with no compromise to the roof integrity, ensuring MIM’s priceless collection has no risk of water damage. The low-profile PowerPly modules will be invisible on our roofline, thus enabling our goal to blend into the landscape and be a timeless part of Arizona.”
The PowerPly technology uses a DuPont Tefzel front sheet and a lightweight composite substrate with high-efficiency monocrystalline silicon solar cells. The module is designed to be applied right onto a flat surface and eliminate racking needs. The solar modules have achieved IEC and UL certification and meet the criteria for a Class B fire rating.
