I have used the Uni-Solar brand panels, because of a few benefits they have over the competition, or at least had a couple of years ago:
They are advertised as bullet proof, (light gauge I'm sure) but it does bode well if you are caught in a hale storm.
Unlike all of their competition, as the temperature rises they work better.
If they are partly shaded, only slightly more than the shaded area of the panel stops working.
The 64 watter is equivalent in both size & output to their oppositions 80 watt panels.
Uni-Solar cost a little more, but personally I wouldn't use anything else.
