High-Speed Monitoring of Multiple Grid-Connected Photovoltaic Array Configurations



Matthew Boyd


Three grid-connected monocrystalline silicon photovoltaic arrays have been instrumented with research-grade sensors on the Maryland campus of the National Institute of Standards and Technology (NIST.) These arrays range from 73 kW to 271 kW and are of different tilts, orientations, and configurations. Irradiance, temperature, wind, and electrical measurements at the arrays are recorded, and images are taken of the arrays to monitor any shading or anomalies. Nearly all measurements are sampled and saved every 1 second, with monitoring having started August 1, 2014. This report describes the instrumentation approach to capture the performance of these photovoltaic systems for use in computer model validation or performance monitoring.
