Sandia uses a few spectral measurements to enhance PV performance models

The power generated by a PV cell depends on both the intensity and spectrum of the light incident on the cell. Silicon solar cells, for example, respond to both visible and near-infrared light, but differently: red light has more impact on PV power output than blue light. Accurately predicting power output requires accounting for the [...]

Fault Detection Tool Project: Automatic Discovery of Faults using Machine Learning

Advanced monitoring of photovoltaic (PV) systems can ensure efficient operations, but extensive monitoring of large quantities of data can be cumbersome for the individual analyst. To address this challenge, Sandia National Laboratories' Fault Detection Tool project uses machine-learning algorithms embedded into data collection devices on-site or at a central server to detect performance issues and failures [...]
