Sandia to Discuss Energy-Storage Test Protocols at the European PV Solar Energy Conference

Researchers from Sandia will give a plenary talk on energy storage test protocols at the European PV Solar Energy Conference (EU PVSEC), to be held in September in Hamburg, Germany. Plenary presentations are given to the entire conference and reserved for outstanding papers which are seen as visionary in the field. In 2014, the conference […]

Sandia Research on Rooftop Structural Strength Gains Attention

Two Sandia research reports, “Structural Code Considerations of Solar Rooftop Installations” and “Empirically Derived Strength of Residential Roof Structure for Solar Installations,” have been featured recently in a number of solar trade outlets.

The reports detail rooftop structural analy­sis conducted by Sandia and funded by the US Department of Energy’s SunShot Initia­tive. Test results indicate that […]

Navy/Marine Engineering Command Visits Sandia

Steven Chung, Naval Facilities Engineering Command, Southwest (NAVFAC SW),1 Dwight Deakin, Naval Air Systems Command (NAVAIR),2 Melanie Anderson (NAVAIR PAX River), and David Weir, Marine Corps Installations–West (MCIWEST-MCB Camp Pendleton)3 visited Sandia June 24–25 to discuss several renewable energy/related topics:

wind-turbine/radar interaction,
photovoltaics (PV), and
cybersecurity as it relates to renewable energy.

They also discussed potential collaboration with Sandia […]

Sandia’s Continuously Recirculating Falling-Particle Receiver Emplaced at Top of Solar Tower

Sandia researchers are working to lower the cost of solar energy systems and improve efficiencies in a big way, thanks to a system of small particles.

This month, engineers lifted Sandia’s continuously recirculating falling-particle receiver to the top of the tower at the National Solar Thermal Test Facility (NSTTF), marking the start of first-of-its-kind testing that […]

DOE-EERE Deputy Assistant Secretary Hollett Visits Sandia

In his role as Department of Energy Office of Energy Efficiency and Renewable Energy (EERE) Deputy Assistant Secretary for Renewable Power, Douglas Hollett oversees research, development, and demonstration of a diverse clean-energy portfolio that includes power generation from wind, solar, geothermal, conventional hydropower, and marine and hydrokinetic resources, as well as grid-integration of these renewable […]

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 DC […]

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 […]
