As I mentioned in the past, we've had de-lamination problems with our Sunware solar panels. Nothing that had actually stopped them from working as far as we can tell, but probably would have eventually.
I'm pleased to report that Sunware stood behind their product and shipped us 6 new panels, via air freight, to replace the failing panels. While installing the replacements is still another project, we're very pleased that the company backed their warranty and sent the replacements.
