A note on flexible panels, I had a bad experience with my Sunpower flexible panels. They need about a 1" gap from the roof (I mounted them directly with tape - this heated up my roof and burned up one panel). I believe this is true of all flexible panels, but other people seem to have better luck so YMMV.
I don’t think this Solaria panel is compatible with my Goal Zero Yeti 1000x (because output voltage is above 50V). Too bad, it looks like an incredible solution.
