# About this Dataset This dataset contains compiled results from annual PV Module Reliability Scorecards published by PV Evolution Labs – also known as PVEL. These scorecards show summary results of PV module testing performed by PVEL and name specific models of PV modules as "Top Performers" in various tests. Full details on testing, Top Performer status and other criteria for inclusion in Scorecards are documented in reports and online documentation available from https://www.modulescorecard.pvel.com. This dataset is not affiliated with PVEL and is intended only to simplify sorting and filtering Scorecard data and finding specific PV module models and Top Performer results. Note that data included in Scorecards has evolved over time, so not all data is available for all years, and testing protocols and Scorecard criteria have been changed over time. Data was compiled by entering information from Scorecards, which are typically published in PDF format. Source Scorecards and/or Executive Summaries in PDF format are included here for posterity. In most cases, apparent issues or inconsistencies were kept as they appear in the Scorecards, these are noted in comments in the XLSX file. ### Description Compiled data is stored in PVEL Scorecard data.xlsx, including all years and individual sheets for each Scorecard. PDF Scorecards or Executive Summaries are found in the "PVEL scorecards" subdirectory. | Field | Description | Units | | --------------------------- | ---------------------------------------------------------------------------------------------------------------- | --------------------------------------- | | Scorecard Year | Year's scorecard | year | | Model Name | Module model name | | | Manufacturer Name | Manufacturer name | | | Pmp Range | Module's maximum power rating falls in this range | W | | Pmp Range Lower | Lower bound of Pmp Range | W | | Pmp Range Upper | Upper bound of Pmp Range | W | | Module Design | Description of module architecture | | | Cell Technology | Cell type including silicon wafer doping (p-type or n-type) and cell architecture (e.g. PERC or TOPCon); or CdTe | | | Number of Cells | Cells per module | | | Cell Format | Cell format (i.e. full or half-cut cells) | | | Wafer Width | Wafer width (not considering cell cutting) | mm | | Thermal Cycling | Top Performer Status in Thermal Cycling | character - "x" indicates Top Performer | | Damp Heat | Top Performer Status in Damp Heat | character - "x" indicates Top Performer | | Mechanical Stress Sequence | Top Performer Status in Mechanical Stress Sequence | character - "x" indicates Top Performer | | PID | Top Performer Status in PID | character - "x" indicates Top Performer | | LID+LETID (2021-) | Top Performer Status in LID+LETID (2021-), test only appeared since 2021 Scorecard | character - "x" indicates Top Performer | | PAN Performance (2020-) | Top Performer Status in PAN Performance (2020-), test only appeared since 2020 Scorecard | character - "x" indicates Top Performer | | Humidity Freeze (2014-2017) | Top Performer Status in Humidity Freeze (2014-2017), test only appeared in 2014-2017 Scorecards | character - "x" indicates Top Performer | | PID+ (2014) | Top Performer Status in PID+ (2014), test only appeared in 2014 Scorecard | character - "x" indicates Top Performer | | Top performer categories | Count of Top Performer status columns | | | Factory Location City 1 | Location of this manufacturer's factory | city name | | Factory Location City 2 | Location of this manufacturer's factory (if applicable) | city name | | Factory Location City 3 | Location of this manufacturer's factory (if applicable) | city name | | Factory Location City 4 | Location of this manufacturer's factory (if applicable) | city name | | Factory Location Country 1 | Location of this manufacturer's factory | country name | | Factory Location Country 2 | Location of this manufacturer's factory (if applicable) | country name | | Factory Location Country 3 | Location of this manufacturer's factory (if applicable) | country name | | Factory Location Country 4 | Location of this manufacturer's factory (if applicable) | country name | ## Authors * **Joseph Karas** -
