Navy/Marine Engineering Command Visits Sandia

Our nation relies upon a network of radars across the country to support the missions of homeland defense/ security, flight safety, and weather forecasting. The air-surveillance environment contains within it clutter, both stationary and moving. Wind turbines present a unique problem in that they can be both stationary and moving clutter and operate with [...]

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. Technologists John Kelton and Daniel Ray (both in Sandia’s Concentrating Solar Technologies Dept.) perform inspection of the falling-particle receiver during a cloud delay atop the NSTTF’s Solar Tower [...]

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

Different types of parallel arc-faults on the DC side of a PV array. 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 [...]

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)

PV fault detection/monitoring system using machine-learning algorithms. A learning algorithm is trained to estimate power production based on meteorological data (irradiance, temperature, wind speed, etc.). This predic-tion is then compared to the actual power to detect various faults. Current research is focused on distinguishing different fault signatures. (Figure from Riley and Johnson, 2012) [...]

Solar Regional Test Center in Vermont Achieves Milestone Installation

Dr. Danielson and Sen. Sanders attend ribbon-cutting ceremony to commemorate the newly installed PV arrays at the Williston, Vermont, RTC site. The solar industry is now more than 60% of the way toward achieving the DOE SunShot Initiative affordability goal of $0.06 per kilowatt-hour for solar electricity. Meeting the last 40% without compromising [...]

Planting the “SEEDS” of Solar Technology in the Home

Sandia researcher Kiran Lakkaraju leads a modeling project that supports the goals of the DOE’s SunShot Initiative. The work aims to create a model that predicts household solar energy system purchases based on such variables as price, energy savings, environ-mental concerns, and other factors. (Photo by Randy Montoya) To better understand what persuades [...]
