Since 2008, Chris Deline has been a research engineer at NREL and currently leads the Photovoltaic (PV) System Performance group. He manages the U.S. Department of Energy Regional Test Center program at NREL for field assessment of novel PV technologies and is principal investigator for multiple PV field performance projects including degradation rate assessment and bifacial module power rating and production modeling. Deline also manages the PV Fleet Performance Data Initiative, which works with commercial fleet owners to aggregate and analyze PV field performance data using novel data quality and performance analysis tools.
Deline is an expert in the field performance of PV modules, particularly partially shaded or mismatched PV including distributed power electronics. His research also includes characterization and energy simulation of advanced PV technologies including thin-film module metastability and bifacial system energy production.
