Dr. Joshua Stephenson Stein
Distinguished Member of Technical Staff

Thursday February 25th 2016 3:30 PM to 4:20 PM
Room 2229 SC
PVLIB is a set of open source modeling functions that allow users to simulate most aspects of photovoltaic (PV) system performance. The functions, in both Matlab and Python, provide users the ability to track the energy of the Sun as it interacts with a PV system and is eventually transformed into usable electric energy that is fed to the grid. This talk will combine an overview of the mathematical and conceptual models used to describe PV system performance as well as demonstrate how these models can easily be run using the PVLIB suite of high level functions. Come learn how to predict the output of a solar PV system!

Presentation Title: “Mining PV system data to identify performance trends”
Dr. Chris Deline
National Renewable Energy Laboratory (NREL), Golden, CO
Thursday October 15th 2015
Seamans Center 3505 at 3:30 PM – 4:20 PM
Abstract: The rapid reduction in photovoltaic (PV) system cost has led to an exponential increase in the number of PV systems installed. Questions have been raised about whether this rapid cost reduction has also resulted in a corresponding reduction in quality and performance for these PV systems. We have also seen an increase in the adoption of distributed power electronics (micro inverters, power optimizers) in PV installations. This provides us an unprecedented level of performance monitoring granularity within the PV system. This talk will describe recent analysis of 50,000 PV systems in the US 1603 Treasury program, and will also discuss the impact of distributed electronics on the design and performance of residential PV systems.
Christopher Deline received the B.S., M.S., and Ph.D. degrees from the University of Michigan, Ann Arbor, in 2003, 2005, and 2008, respectively, all in electrical engineering. His Ph.D. work involved experimental investigation of the magnetic nozzle region of electric propulsion thrusters at NASA MSFC and JSC. Since 2008 he has been a research engineer at the National Renewable Energy Laboratory in Golden, CO in the photovoltaic performance and reliability group. He has co-authored several reports on the performance impact of microinverters and DC-DC converters in PV systems under mismatched and shaded conditions. His research includes PV field performance including thin-film PV performance and stabilization, mismatch and partial shading in PV systems and distributed power electronics for PV. Chris manages the DOE Regional Test Center program at NREL for field assessment of novel PV technologies, and is principal investigator for multiple projects on PV field performance including degradation rate assessment and bifacial module power rating and energy production modeling.
