Anyone familiar with these solar panels??

No idea, but if it helps, the flexible panels were made for recreational use where they might be stepped on, like boats.
My experience with other models (years ago) is that they really stank compared to crystal panels.

But that's not to say that you don't have an applicatiion for trickle charge, etc., that may be ok.

The company has filed for Chapter 11 Bankruptcy. Their web site says their flexible panels produce more electricity than Crystalline PV panels. That I find hard to believe.

Residential Products ? Uni-Solar

There is not a lot of technical data that I could find on their web site. At only 128 watts they are about half the wattage of many standard solar panels, but one really needs to compare that by actual surface area versus the cost.
