Distributed Strain Sensing of a Solar PV single-axis tracking system located at the Nextracker Development Center 

    This project seeks to demonstrate the ability of fiber optic sensing (FOS) technology to produce meaningful data that characterize single-axis tracking systems with regard to dynamic wind loading.  This project will explore the ability of FOS technology to capture frequency modes, deflection of frame members, tables, and modules, and load paths through the tracking system to critical fasteners and mounted modules.  This project will demonstrate and explore the physical application of FOS systems to arrays along with such topics as fiber and adhesive longevity to weathering.
