Second Annual Electric Power Research Institute/Sandia Photovoltaic Systems SymposiumSandia 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: PV performance modeling; screening methods, distribution PV host­ing capacity, and advanced inverter modeling; and PV system reliability and maintenance strategies. Sandians […]
PV Value® Tool Featured at Washington D.C. RoundtableGeoff 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 of Economic Resilience and the Executive Office of the President on March 11, 2014. The PV Value® tool, co-developed by Sandia and Energy Sense Finance, was presented as a successful application […]
Solar Glare Hazard Analysis Tool Available for DownloadSandia 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 […]
Federal Electric Regulatory Commission Revised Its Small Generator Interconnection Procedure and Small Generator Interconnection AgreementAfter 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-Electric Power Research Institute Partnership Publishes Photovoltaic Reliability ReportSandia and the Electric Power Research Institute (EPRI) are jointly engaged in a multiple-year research effort to examine photovoltaic (PV) plant reliability performance obtained through documented field data. Findings and analyses, derived from the PV Reliability Operations Maintenance (PVROM) database, are intended to inform industry best practices around the optimal operations and maintenance (O&M) of […]
Sandia PV Team Publishes Book ChapterThe book, Solar Energy Forecasting and Resource Assessment, provides an authoritative voice on the accuracy of long-term resource projections and addresses grid operators’ concerns about variable short-term power generation, incorporating contributions from an internationally recognized group of top authors from both industry and academia, focused on providing information from underlying scientific fundamentals to practical applications […]
Sandia R&D Funded under New DOE SunShot ProgramOn 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 VermontU.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 Labs Harnesses the Sun’s Energy with Tiny ParticlesEngineers at Sandia, along with part­ner institutions Georgia Tech, Bucknell University, King Saud University, and the German Aerospace Center (DLR), are using a falling-particle receiver to more efficiently convert solar energy to electri­city in large-scale, concentrating solar power (CSP) plants. Falling-particle receiver technology is attractive because it can cost-effectively capture and store heat at higher […]
Sandia Will Host PV Bankability Workshop at Solar Power International (SPI) 2013On October 21, Sandia’s Joshua Stein, Melissa Sisneros, and Bruce King (all in the Photovoltaic & Distributed Systems Integration Dept.) will host a workshop on demonstrating strategies for defining the bankability of new PV products, “Driving the Commercialization of New Solar Technologies: What You Can Learn with the U.S. DOE Regional Test Centers toward Demonstrating […]
