A 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 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 DC […]

On 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 […]
Solar energy is both predictable—the sun rises and sets everyday—and intermittent—a passing cloud can reduce a 1 MW photovoltaic (PV) array from 100% of its power generating capacity to 10% in a matter of seconds. This intermittency limits this renewable-energy (RE) source and how much of it is integrated into today’s electricity grid.
To alleviate this […]
A report released recently by Sandia National Laboratories, the Electric Power Research Institute (EPRI), and the Georgia Institute of Technology provides a unique approach to help utilities assess the potential effects of high levels of solar photovoltaic (PV) systems on the grid. “Time Series Power Flow Analysis for Distribution Connected PV Generation” demonstrates how quasi-static […]
ECIS has developed a new external website to facilitate the functions of the five DOE RTCs—both interacting with each other to fulfill the overall DOE objectives and with partners in the U.S. PV industry. The site houses project updates, news, and events as well as controlled access for project file sharing.
The DOE has commissioned five […]
Sandia’s Photovoltaic (PV) Arc-Fault Detection and Mitigation team has gained worldwide renown as a leader in the science of PV arc faults. As a driver of groundbreaking experimental and numerical simulations in this area, codes and standards bodies have called on Sandia to improve requirements for arc-fault circuit interrupters. Sandia
has advised the National Electrical Code […]
