I have some Sanyo panels that are developing silvery spots next to the traces on the front of the cells. Two of the panels have significant areas that have become very hot, forming bubbles on the back, and those two are way down in output. Panasonic says the silvery spots are not a problem (and my testing shows except for the two really bad ones, so far most of the panels are producing well within the acceptable output). My questions; can anyone tell me what the problem here is? And, is anyone else having problems getting Panasonic to warranty Sanyo panels, or does anyone have a suggestion as to what I can do to get this resolved? It has been some time since Panasonic first got pictures and test results, and they seem to be dragging their feet. I'm afraid they will be out of business before they take care of this.
