Sandia Rooftop PV Structural Report Webinar

A roof structure is made stronger by the system elements working together—much stronger than its main load-bearing element, the rafter, is alone. Current engineering analysis methods do not take this composite action into account when evaluating rooftop strength. Results from the Sandia research reports, “Structural Code Considerations of Solar Rooftop Installations” and “Empirically [...]

Sandia Research on Rooftop Structural Strength Gains Attention

A roof structure is made stronger by the system elements working together—much stronger than its main load-bearing element, the rafter, is alone. Current engineering analysis methods do not take this composite action into account when evaluating rooftop strength. Two Sandia research reports, “Structural Code Considerations of Solar Rooftop Installations” and “Empirically Derived Strength [...]

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 [...]

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. Sandia researcher Vitalie Stavila inserts a substrate patterned with electrodes into a temperature-controlled liquid-phase reactor for depositing MOF thin [...]

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 [...]

Federal Electric Regulatory Commission Revised Its Small Generator Interconnection Procedure and Small Generator Interconnection Agreement

After two years of industry consultation, the Federal Electric Regulatory Commission (FERC) has issued a final ruling on the much anticipated modification of the FERC Small Generator Interconnection Procedure (SGIP) which governs the interconnection of small generators (smaller than 20 MW) that sell wholesale electricity. The SGIP also serves as a template for state rules that [...]

Sandia R&D Funded under New DOE SunShot Program

On October 22, the Department of Energy announced $60M in new awards to drive affordable, efficient so­lar power. The SunShot Physics of Reliability: Evaluating Design Insights for Component Technologies in Solar (PREDICTS) program is taking a physics- and chemistry-based approach to identifying solar product failure modes. Module-level (~200 W) power electronics (MLPE), such as microinverters, microconverters, [...]

Launch of Solar Testing Site in Vermont

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). [...]

Sandia Report Offers Reliable Way to Evaluate Unintentional Islanding Risk

A recently released Sandia National Laboratories report, "Suggested Guidelines for Assessment of DG Unintentional Islanding Risk," outlines a procedure to help utility distribution engineers determine the risk of unintentional islanding in distributed energy generation installations. By providing a quick and reliable way to identify situations in which such risk is negligible, Sandia’s approach can help [...]
