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 […]

Combining ‘Tinkertoy’ Materials with Solar Cells for Increased Photovoltaic Efficiency

Sandia researchers have received a $1.2M award from the DOE’s SunShot Initiative to develop a technique that they believe will significantly improve photovoltaic (PV) materials efficiency and help make solar electricity cost-competitive with other energy sources.

The work builds on Sandia’s recent successes with metal-organic framework (MOF) materials by combining them with dye-sensitized solar cells (DSSCs). DSSCs, […]

Solar Glare Hazard Analysis Tool Available for Download

Sandia developed the Solar Glare Hazard Analysis Tool (SGHAT), a web-based tool that predicts energy production and the potential for solar glare and ocular impacts from an array of photovoltaic (PV) panels.

SGHAT uses an interactive Google Maps interface together with a few user-specified parameters such as orientation and tilt of the PV panels to quickly

Launch of Solar Testing Site in Vermont

U.S. Senator Bernie Sanders (I-VT) joined representatives of Sandia, IBM, and the DOE in early November to announce the launch of the Vermont Photovoltaic Regional Test Center (RTC). The RTC will enable research on integrating solar panels into the statewide smart grid and help reduce the cost of solar power. The Vermont RTC is one […]

Sandia and EMCORE: Solar Photovoltaics, Fiber Optics, MODE, and Energy Efficiency

MODE (MicroOptical Devices) was an Albuquerque-based start-up company founded by a group of Sandians who left Sandia under a special entrepreneurial program. MODE was purchased in 1997 by EMCORE, a New Jersey company that has worked with Sandia since the early 1990s.
Upon acquiring MODE, EMCORE became the first company to build a facility in the […]
