In June 2018 the International Electrotechnical Commission (IEC) published a new edition of the test methods used for testing solar products, IEC 62257-9-5:2018 (also written as IEC 62257-9-5 ed. 4). It will take our program and the associated test labs some time to phase in use of this new document. This memo describes the associated changes and expected timelines.
This memo also describes changes to the quality standards for pico-PV products which were implemented on December 1, 2018.
