[RE-wrenches] whos doing the PV testing

[David Brearley]

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:  
10.2    Maximum Power Determination 
10.4    Measurement of Temperature Coefficients 
10.5    Measurement of NOCT 
10.6    Performance at STC and NOCT 
10.7    Performance 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
