Photovoltaic Module Current-Voltage and Electroluminescence Image Data (PV-IV-EL)

Description

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.

57 Electroluminescence (EL) image data. The EL files include images taken with modules biased for high and low current injection (~20% and ~80% of module short-circuit current). Each EL image was captured using a modified astronomical camera (FLI Proline, Finger Lakes Instrumentation, IDEX Health & Science LLC, New York, USA) with a 35 mm lens. Exposure time for each module was varied such that a balanced histogram image is obtained. Imaging settings are listed in the metadata file AnonDB. https://data.openei.org/files/8378/EL.zip
57 The RefIV files are the first current-voltage characteristic captured for each module, typically upon receipt and before the module is fielded. These IV curves are taken under the same conditions as the IV files listed above. https://data.openei.org/files/8378/RefIV.zip

57 Current-voltage trace (IV) flash test data. The IV files include current-voltage characteristics acquired in the forward direction (sweeping voltage from short circuit to open circuit) at 1-sun (1000 W/m2) with a with a AAA rated flash tester (Spire Spi-Sun Simulator 4600SLP, Spire Solar, Bedford, MA). Modules were thermally equilibrated to 25 degrees C before measurement at STC. IV characterization metadata are also listed in AnonDB. https://data.openei.org/files/8378/IV.zip
8 Metadata of photovoltaic module data, and associated current-voltage curve and electroluminescence image data. The AnonDB.csv file contains metadata for each module in the dataset, and provides information on each of the IV and EL measurements. https://data.openei.org/files/8378/AnonDB.csv
