ECIS, Lockheed Martin Aeronautics, University of New Mexico, and Davidson College: Multifunctional Optical Coatings by Rapid Self-Assembly

Optical coatings appear on items ranging from electronic devices, photographic lenses, and windows to aircraft sensors, photovoltaic cells, and goggles for troops in the field. The coatings protect or alter the way a material reflects and/or transmits light. However, the two primary methods of applying coatings—sputtering and chemical vapor deposition (CVD)—are expensive, require highly specialized [...]

ECIS-Princeton Power Systems, Inc.: Demand Response Inverter

Solar energy is both predictable—the sun rises and sets everyday—and intermittent—a passing cloud can reduce a 1 MW photovoltaic (PV) array from 100% of its power generating capacity to 10% in a matter of seconds. This intermittency limits this renewable-energy (RE) source and how much of it is integrated into today’s electricity grid. To alleviate [...]

Release of Version 1.1 of the PV_LIB Toolbox for Matlab

The PV Performance Modeling Collaborative (PVPMC) recently released version 1.1 of the PV_LIB Toolbox for Matlab. The new version includes important bug fixes and many new and useful functions, including support for the single diode module model, clear sky irradiance models, incident angle modifier models and more! Sandia facilitates the PVPMC, a group of over [...]

Study Rebuts Hypothesis That Comet Attacks Ended 13,000-Year-Old Clovis Culture

Rebutting a speculative hypothesis that comet explosions changed Earth’s climate sufficiently to end the Clovis culture in North America about 13,000 years ago, Sandia lead author Mark Boslough (Discrete Mathematics & Complex Systems Dept.) and researchers from 14 academic institutions assert that other explanations must be found for the apparent disappearance. “There’s no plausible mechanism to [...]

Sandia Offers Approach to Help Utilities Understand Effects of PV Variability on the Grid

A report released recently by Sandia National Laboratories, the Electric Power Research Institute (EPRI), and the Georgia Institute of Technology provides a unique approach to help utilities assess the potential effects of high levels of solar photovoltaic (PV) systems on the grid. “Time Series Power Flow Analysis for Distribution Connected PV Generation” demonstrates how quasi-static [...]
