Developing cost-effective, reliable PV energy systems and accelerating the integration of PV technology

Photovoltaic (PV) research at Sandia focuses on developing and improving PV technologies and applications by lowering cost and increasing performance and reliability of PV components and systems. Sandia specializes in performance modeling, characterization, and transmission and distribution grid integration. Sandia researchers support the U.S. Department of Energy’s SunShot Initiative and partner with industry, utilities, academia, and other laboratories to make PV power systems more cost-competitive and to remove barriers to large-scale deployment on the grid.

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: [...]

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 [...]

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. [...]

Sandia Labs and NREL Hosted Successful 2016 PV Reliability Workshop
