[RE-wrenches] bubbling Sanyo modules

[William Dorsett]

On Sunday, I noticed a Sanyo HIT system we put in about the same time was
dirty so I stopped, hooked up their garden hose and rinsed it off. There is
a disturbing yellow modeling that appears to be under the glass though I
won't know until I get some soap and really wash it. Kind of gave me flash
backs of the old Carrizo's though there is no reason for concentrated light
on this one. ???

Randy,

We installed Sanyo's for a couple seasons and I have one job with similar
bubbling.  The bubbles have grown pretty large, but Sanyo feels that it is
not a warranty claim until the module fails.  I think that one module with
this issue along the frame will eventually fail.  But we are past the 2 year
warranty of defects at this point.

Hi Wrenches,
I have some Sanyo HIT modules in operation since 2006, that are bubbling in
the back. The bubbles are small perfectly rectangular shapes, smaller than
the cell, a few per module. I put an IR camera on it and didn't see any
additional heat. I also did an IV test and got good results.  Anyone seen
something like this that led to a problem. (question mark) My keyboard
question mark doesn't work after I spilled tea on my keyboard.
Thanks
