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 […]

Direct Measurement of Key Molecule Will Increase Accuracy of Combustion Models

Sandia researchers are the first to directly measure hydroperoxyalkyl radicals—a class of reactive molecules denoted as “QOOH”—that are key in the chain of reactions that controls the early stages of combustion. This breakthrough has generated data on QOOH reaction rates and outcomes that will improve the fidelity of models used by engine manufacturers to create […]

SolarReserve Is Testing Prototype Heliostats at NSTTF

SolarReserve is testing engineering units at the National Solar Thermal Test Facility (NSTTF) operated by Sandia. The company says it decided to test its prototype heliostats at NSTTF because of Sandia’s, “knowledge and reputation in the solar industry, as well as the breadth of resources available for improving and testing new designs.” SolarReserve is focused […]
