Sandians Win ‘Best Paper’ Award at Photovoltaic Conference in Japan

A research team that included Sandians Clifford Hansen and Joshua Stein (in Sandia’s Photovoltaic & Distributed Systems Integration Dept.) and Katherine Klise (in Sandia’s Geotechnology and Engineering Dept.) received a Best Paper Award for their work “Photovoltaic System Model Calibration Using Monitored System Data,” presented at the 6th World Conference on Photovoltaic Energy Conversion (WCPEC) […]

Sandia Research on PV Arc-Fault Detection Submitted for US Patent

Sandia National Laboratories/Tigo Energy researchers recently submitted an application for a US patent related to research on arc-fault detection and circuit interruption in solar photovoltaic (PV) systems. Sandia’s patent-pending methods, filed as Identifying an Arc-Fault Type in Photovoltaic Arrays, allow AFCIs to distinguish between series and parallel faults. The 2011 National Electrical Code® requires PV […]

PV Plant Performance Technical Briefing Published in PV Power Tech

The state of the art in PV system monitoring is relatively simplistic, relying either on comparisons of outputs between various parts of the system (e.g., inverters) or on an evaluation of a performance metric that normalizes output to available irradiance and other environmental conditions. However, neither of these methods is very effective in discovering the source […]

Sandian Presents on PV Failure Analysis at European PV Solar Energy Conference and Exhibition (EU PVSC)

Sandia researcher Joshua Stein (in Sandia’s Photovoltaic & Distributed Systems Integration Dept.) highlighted novel PV array monitoring strategies at a PV Performance Analysis and Module Reliability workshop held at the European PV Solar Energy Conference and Exhibition in Amsterdam, Netherlands. The talk was coauthored by Mike Green from MG Lightning Electrical Engineering in Israel. Under […]

Sandian Recognized as a Top Professional in Energy

Sandia’s Kenneth Armijo (in the Photovoltaic & Distributed Systems Integration Dept.) was recognized in Hispanic Engineer and Information Technology magazine’s Fall 2014 issue as a “top professional in energy” in their article, “Where Does the Energy Sector Find Its Next-Gen Stars?” Dr. Armijo is a research scientist who holds a Ph.D. in Mechanical Engineering from […]
