Sandians Win ‘Best Paper’ Award at Photovoltaic Conference in JapanA research team that included Sandians Clifford Hansen and Joshua Stein (in Sandia’s Photovoltaic & Distributed Systems Integration Dept.) and Katherine Klise (in Sandia’s Geotechnology and Engineering Dept.) received a Best Paper Award for their work “Photovoltaic System Model Calibration Using Monitored System Data,” presented at the 6th World Conference on Photovoltaic Energy Conversion (WCPEC) […]
Sandia Research on PV Arc-Fault Detection Submitted for US PatentSandia National Laboratories/Tigo Energy researchers recently submitted an application for a US patent related to research on arc-fault detection and circuit interruption in solar photovoltaic (PV) systems. Sandia’s patent-pending methods, filed as Identifying an Arc-Fault Type in Photovoltaic Arrays, allow AFCIs to distinguish between series and parallel faults. The 2011 National Electrical Code® requires PV […]
PV Plant Performance Technical Briefing Published in PV Power TechThe 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 effective in discovering the source […]
SolarReserve Is Testing Prototype Heliostats at NSTTFSolarReserve is testing engineering units at the National Solar Thermal Test Facility (NSTTF) operated by Sandia. The company says it decided to test its prototype heliostats at NSTTF because of Sandia’s, “knowledge and reputation in the solar industry, as well as the breadth of resources available for improving and testing new designs.” SolarReserve is focused […]
Price Premiums for Solar Home SalesA Lawrence Berkeley National Laboratory (LBNL) -led multi-institutional research team, with Sandia (Geoffrey Klise, in Sandia’s Earth Systems Analysis Dept., contributing the Sandia-developed PV Value whole-system appraisal tool, among other things), universities, and appraisers found that home buyers have consistently been willing to pay more for homes with solar PV energy systems—averaging ~$4/watt of PV […]
Sandian Presents on PV Failure Analysis at European PV Solar Energy Conference and Exhibition (EU PVSC)Sandia researcher Joshua Stein (in Sandia’s Photovoltaic & Distributed Systems Integration Dept.) highlighted novel PV array monitoring strategies at a PV Performance Analysis and Module Reliability workshop held at the European PV Solar Energy Conference and Exhibition in Amsterdam, Netherlands. The talk was coauthored by Mike Green from MG Lightning Electrical Engineering in Israel. Under […]
Sandian Recognized as a Top Professional in EnergySandia’s Kenneth Armijo (in the Photovoltaic & Distributed Systems Integration Dept.) was recognized in Hispanic Engineer and Information Technology magazine’s Fall 2014 issue as a “top professional in energy” in their article, “Where Does the Energy Sector Find Its Next-Gen Stars?” Dr. Armijo is a research scientist who holds a Ph.D. in Mechanical Engineering from […]
Sandian Selected for Outstanding Engineer AwardThe Institute of Electrical and Electronics Engineers (IEEE) Region 6: Southwest Area (encompassing New Mexico, Arizona, California, and Nevada) has selected Dr. Jose Luis Cruz-Campa (in Sandia’s MEMS* Technologies Dept.) as the recipient of their 2014 Outstanding Engineer Award for his “critical technical and leadership contributions to the development of microsystems-enabled PV (MEPV) technology and […]
PV Performance Modeling Collaborative’s New and Improved Website Is LaunchedThe PV Performance Modeling Collaborative (PVPMC) is excited to announce the launch of our newly redesigned Web site located at the new address: https://pvpmc.sandia.gov. The new site’s homepage welcomes visitors with a clean uncluttered design, with featured content focused on our mission to provide you with the most accurate information, strengthen partner relations, and share […]
Combining ‘Tinkertoy’ Materials with Solar Cells for Increased Photovoltaic EfficiencySandia 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. The work builds on Sandia’s recent successes with metal-organic framework (MOF) materials by combining them with dye-sensitized solar cells (DSSCs). […]
