I have a few dozen of these new old stock CIGS solar panels. The great thing about these compared to most flexible solar panels is the durability. These can be glued down and walked on seemingly without damage. They were designed to be put on commercial rooftops so longevity should be much better compared to a monocrystalline flexible solar panel. You can see in the photo it looks like three pieces to the panel, I also have panels that are 1/3 this size for fitting in smaller spaces.
This panel is 160 Watts. I am happy to help you through the details of connecting this and getting you the right wire, fuses, charge controller, etc.
These numbers are from the tag on the panel:
