The International PV Quality Assurance Task Force (PVQAT, "PV cat") leads global efforts to craft quality and reliability standards including:
A rating system to ensure durable design of PV modules for the climate and application of interest
A guideline for factory inspections and quality assurance (QA) during module manufacturing
Comments from the IEC National Committees were received for IEC/TS 62941 Ed. 1 "Guideline for increased confidence in PV module design qualification and type approval." The comments encouraged creation of a checklist to aid in more consistent application of the Technical Specification. Revisions in response to the comments are underway.
