Microsoft Outlook SignatureI'm curious to see if this little excel spreadsheet PTC calculator that I got from the CEC in 2003 attaches.

  Jerry,
  The CEC formula for PTC uses the NOCT of the module, the STC rating, the power temperature coefficient and the aperature area of the module.  
  The data is supplied by the manufacturer but must make sense.  Starting July 1, 2009, this will have to be certified by an acredited testing lab.
  Let me know if you want the exact formula and i will send it to you.  i can't attach anything to this email

    Wrenches,

    Can anyone tell how PTC ratings are determined for modules on the CEC list of eligible modules?  I seem to recall having heard that the manufacturers provide this data on the honor system.  Can anyone verify this?

    The test is obviously more involved than flash testing at STC.  Even though PTC is supposed to simulate more real-world conditions, it must still require a controlled environment.  How exactly is this done, and how long does it take?

    Best,
