Navy/Marine Engineering Command Visits Sandia
News Article, July 15, 2015 • 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...

PV Plant Performance Technical Briefing Published in PV Power Tech
News Article, March 4, 2015 • 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...
