According to Pat Saxon at the California Energy Commission, the list of approved test facilities currently include: CSA, Intertek (ETL) and UL. TUV Rheinland of North America is in the process of expanding their scope to include this testing. The testing performed includes portions, but not all, of IEC 61215 (for c-SI) and IEC 61646 (for thin film). The nominal operating cell temperature (NOCT) and the temperature coefficient of power measurements reported from these third party testing laboratories are now used to derive the PTC ratings for CEC eligible modules. That’s basically the change; previously these values were self-reported by the manufacturers, generally optimistically.<BR>

A section in one of our feature articles, a recent Q&A response and a letter in our Mail department cover aspects of the new testing. If you would like me to send you links or PDFs to these sources just contact me offline.<BR>
