We thank everyone who provided feedback on the proposal to integrate the QA frameworks for pico-solar products and solar home system (SHS) kits in June of 2016. Based on the feedback we have received and the experience we have gained from conducting pilot and validation testing on a range of both pico-products and SHS kits, we are nearly ready to submit a revised version of IEC TS 62257-9-5 that covers off-grid solar products ranging from less than one watt up to 350 watts. We believe the proposed framework will create a unified set of test methods that can more easily be maintained and will ensure a more efficient and appropriate testing process.

A synthesis of comments on each question or sub-topic is presented, along with responses from the Lighting Global team. While text was altered from the original submissions, alterations were not intended to change the meaning of the comment, but only to condense responses and protect the anonymity of the respondent. Similar comments from multiple stakeholders were combined.

This document was produced by Lighting Global Quality Assurance. In February 2020, Lighting Global Quality Assurance evolved to become VeraSol, an independent program offering quality assurance services for solar energy kits and off-grid appliances.
