High-Temperature Falling Particle Receiver Reaches New Limits

At its National Solar Thermal Test Facility, Sandia National Laboratories recently completed a 3½-year project funded by DOE’s SunShot Initiative to develop a high-temperature falling particle receiver, in which sand-like ceramic particles are heated as they fall through a beam of highly concentrated sunlight focused by an array of mirrors.  The falling-particle receiver enables concentrated [...]

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, [...]

University of Illinois uses Sandia Labs’ reference hydrokinetic turbine to study potential bed erosion effects

Sandia Labs Water Power Technologies Department promotes open-source marine hydrokinetic research by disseminating information on MHK technology designs initially developed as reference models to benchmark performance and costs. Sandia developed a scale model of a reference hydrokinetic turbine to minimize power performance losses from soiling/bio­fouling and reduce the likelihood of cavitation. Researchers at the University of Illinois Ven Te Chow Hydrosystems Laboratory recently tested the model to evaluate [...]
