Abstract
This work aims to investigate the deployment of a reflectometry testing method for the online monitoring of photovoltaic (PV) systems. The reflectometry for frequency domain reflectometry (FDR) and spread spectrum time domain reflectometry (SSTDR) are developed at the Accelerated and Real-Time Environmental Nodal Assessment (ARENA) testbed for the Integrated Renewable Energy System (IRES) at Pacific Northwest National Laboratory. Different from traditional fault detection in commercial PV strings, reflectometry approaches can not only detect but also locate a large variety of anomalies by monitoring impedance discontinuities, such as mechanical damage, aging caused by ultraviolet light and high temperature, moisture ingress, transients, and more. Deployment of reflectometry for online monitoring of PV systems is expected to increase the efficiency of installation, operation, and maintenance (IO&M) of PV systems towards 50-year lifetimes.
