Re: [RE-wrenches] whos doing the PV testing
Jay, 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. That¹s basically the change; previously these values were self-reported by the manufacturers, generally optimistically. A section in one of our feature articles, a recent QA 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.

Re: [RE-wrenches] whos doing the PV testing
Yes, the 3rd-part labs determine the temp coefficients. From the ³PV Module Eligibility Procedure² PDF on gosolarcalifornia.org: ³The process for adding PV modules to the SB1 list is as follows: 1. The manufacturer gets their product certified to UL 1703. UL, CSA, and Inte rtek are the NRTLs who can currently perform this testing. 2. The manufacturer gets additional performance parameter testing completed by an ILAC-affiliated laboratory as listed above. Detailed information on the tes ts can be found on the equipment request form in Step 3. The additional performance p arameter testing required is shown below: Crystalline modules IEC 61215 Sections: 10.2Maximum Power Determination 10.4Measurement of Temperature Coefficients 10.5Measurement of NOCT 10.6Performance at STC and NOCT 10.7Performance at Low Irradiance 3. The manufacturer fills out the Energy Commission equipment application form, found here: http://gosolarcalifornia.org/equipment/documents/EQUIPMENT_REQUEST.DOC 4. The manufacturer emails a copy of the UL 1703 Certification Letter, the ILAC laboratory test report, and the Energy Commission equipment application form to Daria M ashnik. All documentation must be in English KEMA will reject any test reports tha t are not in English.² On 9/30/09 10:28 AM, jay peltz j...@asis.com wrote: Hi David, Yes I saw the piece in the new SolarPro.
