Demonstration of PV modules with lightweight mounting systems on commercial rooftops

Lightweight mounting systems reduce hardware and labor costs associated with a typical rooftop PV installation. PVMC fabricated innovative lightweight mounts for PV modules that eliminated traditional racking and ballasting materials. Seven (7) prototype systems (each system <; 3 kW) using rigid and flexible PV modules from multiple manufacturers were deployed on TPO (Thermoplastic Polyolefin), EPDM (Ethylene Propylene Diene Monomer), and standing seam metal roofs. A Prototype Demonstration Facility (PDF) consisting of a mock roof at ground level was built to deploy these PV systems and allow easy installation and maintenance access. The prototype PV systems are under electrical monitoring to determine the effects of the mounting mechanism on the performance of PV modules.
