Sandia and Electric Power Research Institute (EPRI) are delighted to host the second joint symposium on technical issues related to photovoltaic (PV) systems and related technologies. This year, the symposium will cover three areas: Sandia researcher Matt Lave uses pyranometers like these to measure the amount of irradiance, or available sunlight. This device employs [...]
Sandia researcher Geoff Klise worked with Solar Power Electric to develop a tool that can be used to appraise photovoltaic installations on homes and businesses. (Photo by Randy Montoya) Geoff Klise (in Sandia’s Earth Systems Analysis Dept.) attended the 2014 Green Mortgage Appraisal Roundtable, hosted by the Federal Housing Administration–Single Family Housing Office [...]
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. Glare viewed from the air traffic control tower at Manchester/Boston Regional Airport. SGHAT uses an interactive Google Maps interface together with [...]
Total Maintenance Actions per Component. This “button” chart shows the total number of maintenance actions across all system components per month. Color coding is used to differentiate each component. [Note: CTRLBRD = Inverter Control Board; CRTLSW = Inverter Control Software; CPS = Inverter Control Power Supply; CYL = hydraulic cylinder; DAS = Data Acquisition [...]
Sandia's Steve Rottler delivers his remarks at the groundbreaking ceremony for the DOE-funded photovoltaic Regional Test Center (RTC) on the IBM campus in Williston, 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). [...]

(Photo credit: Charles Robinson) HelioVolt, Sandia National Laboratories, the National Renewable Energy Laboratory, and the Florida Solar Energy Center are pleased to announce the successful grid connection of the first half of six arrays to be deployed at the U.S. Department of Energy Regional [...]
Glare viewed from the air traffic control tower at Manchester/Boston Regional Airport. (April 27, 2012, at 8:15 a.m.) Sandia researchers—competing in an international pool of universities, corporations, and government labs—captured three R&D100 Awards in this year’s contest. R&D Magazine presents the awards each year to researchers whom its editors and independent judging panels [...]
Matthew Lave is a Ph.D. student at the University of California, San Diego (UCSD). Matthew’s research focuses on variability analysis of solar radiation and solar power. His Ph.D. thesis is exploring upscaling and downscaling solar radiation time series using wavelets. Sandians Mathew Lave and Joshua Stein ( both in the Photovoltaics and Distributed [...]
