The panel was sourced from FastTech costing USD$20.90 and the panel weighs in at 109g but it looks trimmable - remove the eyelets and trim in a cm all round will get it under 100g. The packaging claims they are top quality Sunpower cells with 23.5% efficiency but the panel is lacking the cloth wrapping and pouch shown on the box which is a great thing as it doubles the weight. TH package comes with two small carabiners and four suction cups for attachment. The panel is nicely flexible so I will just make a sil-nylon stuff sac for it - no need for stiffening or padding.
Now to test it out.

Intermittent sun and cloud over the next hour increased the charge to 48%.

Then I waited and waited for close to 4 weeks before delivery. I thought it got lost. No ideas why it took 4 weeks to travel the last leg.

It doesn't look like it's designed to fold and I would expect it to either snap or be significantly affected if I did try to fold it.
Anyone tried to fold theirs?
