Update on efforts of the International PV QA Task Force

Update on efforts of the International PV QA Task Force (PVQAT) and Associated Standards Work by the International Electrotechnical Commission (IEC)

By Sarah Kurtz, NREL

Quality Management

A primary effort of PVQAT has been development of a guide for ensuring robust and consistent implementation of designs qualified to IEC 61215.  In collaboration with PVQAT, the IEC is nearing completion of this Technical Specification (IEC/TS 62941 Ed. 1 draft).  A report summarizing this work will be released within the next month on NREL’s web site and the Technical Specification is scheduled for publication by the end of 2015. Consistent implementation will be overseen by IECEE and IECRE who are developing an example checklist and the training requirements for auditors as part of the procedure for certification of the auditors. Substantial progress toward these goals was made during discussions at the PVQAT Workshop held in Golden, Colorado on Wednesday, February 25, 2015.

Climate-specific Qualification Testing

IEC 62892-1 (draft) “Testing of PV modules to differentiate performance in multiple climates and applications – Part 1: Overall test sequence and method of communication” was also discussed at the workshop last week.  Specifically, the discussion concluded that it would be valuable to be able to complete the new test sequence following completion of IEC 61215.  The Committee Draft of IEC 62892-1 is currently being circulated with comments due April 24, 2015.

IECRE

IECRE was formed to provide a means for system-level verification of renewable energy systems, including wind, solar, and marine systems.  Currently, 18 nations have joined and Rules of Procedure are being drafted.  A second meeting of the Rules of Procedure Task Group was held in Spain in November.  The next meeting of the PV Operating Management Committee (PV-OMC) will be held in May in Germany. Standards are being identified or developed to complete all of the steps that would be useful for a PV system certification.  If you are interested in joining this effort, please contact George Kelly george@sunset-technology.com.
