A Uniform Taxonomy for Photovoltaic System Operations and Maintenance Data

Hansen, Clifford; Rossman, A.J.; Nagel, James

We outline a uniform taxonomy for photovoltaic (PV) system operations and maintenance (O&M) data. For example, such data include time-series of power, voltage, and meteorological measurements, records of instrument cleaning and calibration, records of O&M-related activities such as inspections, and records of events such as device failures. The described taxonomy provides structured models for all these data using consistent terms and classifications. A uniform taxonomy is enables analytics spanning across systems and portfolios of systems.
