Photovoltaic Module Current-Voltage and Electroluminescence Image Data (PV-IV-EL)
This dataset consists of 613 sets of corresponding current-voltage trace (IV) flash test data and electroluminescence (EL) image data for commercial PV modules from the Photovoltaic Systems Evaluation Laboratory at Sandia National Laboratories. PV modules are from fielded systems in Albuquerque, New Mexico, USA. Measurements of corresponding IV and EL data were taken over a 6 year period, with modules removed from the field and measured in the laboratory at 0 to 5 years of outdoor exposure. The 438 unique modules comprise 28 unique module models from 17 different brands, which are anonymized in the metadata. Additional metadata include current-voltage and electroluminescence acquisition parameters, and length of outdoor exposure.
For more metadata information see the AnonDB.csv file, which contains metadata for each module in the dataset, and provides information on each of the IV and EL measurements. Descriptions of each column in the AnonDB.csv file are listed under the "AnonDB Descriptions" resource linked below.
This project was funded under award "PV Proving Grounds" numbers 38268 and 52787.
