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 [...]

Preliminary Results of Bifacial Project Released on the PVPMC

As reported on the PV Performance Modeling Collaborative (PVPMC), Sandia Labs is leading a three-year research project to study bifacial photovoltaic technology and performance. The project is sponsored by SunShot, a U.S. Department of Energy program. Conventional PV cells convert light hitting the front side of the cell to electricity. With a few extra processing steps, [...]

Sandia defines solar variability zones

Sandia Labs has defined solar variability zones by modeling solar variability across the country using a combination of ground measured and satellite derived solar irradiance measurements. The zones represent the magnitude of high-frequency (sub-minute) solar variability—changes in available sunlight—at each location. Photovoltaic (PV) installations in locations with higher solar variability can, all else being equal, [...]

Sandia Labs releases wavelet variability model (WVM)

When a single solar photovoltaic (PV) module is in full sunlight, then is shaded by a cloud, and is back in full sunlight in a matter of seconds, a sharp dip then increase in power output will result. However, over an entire PV plant, clouds will often uncover some modules even as they cover others, [...]
