Hi Larry, We were just called out to an offgrid system that has the Kyocera 120-1's with the 2001.5 date on them. 10 out of 16 appear to have burned contacts/traces on them. Who is the contact or go to person on this at Kyocera?

Example: The 1999 through 2002 Kyocera KC120-1's have been failing in the thousands. A poorly soldered contact opens and 1/2 the module stops passing power (Voc 10.5 V). To date, Kyocera is still exchanging these with remanufactured units without any legal liability to do so. They even pay us the labor to replace them more than 10 years out of warranty. They have my kudos for the way they are handling this. A manufacturer will be on my sh!t list if they don't stand behind an obvious production failure that is occurring in many modules. I hope this is not the case with these Sanyo.

That warranty should be good for 25yrs. Anyone care to comment on that reasoning? benn In a way, I don't quite understand the difference. If a module plain old stops working because of workmanship or whatever, isn't 0% of original output less than 80% of original output ?? boB
