Things have sure changed since I used to go backpacking. My only electric device used to be a flashlight. And given the cheap plastic construction and the fragile incandescent bulbs, the thing was usually broken within 24 hours, leaving me with zero electrical devices.
Personally, I would try to cut down on the electronics I was carrying, not increase my power generation status. And for the devices I felt I couldn't get rid of, I'd carry a Li-Ion powerbank or two to charge them with. A solar panel setup large enough to be even marginally useful is going to be a deployment nightmare IMHO. Large. Heavy. Fragile. Awkward. Time consuming. Expensive. I can maybe see a use case if you were stationary for long periods, but not so much if you're moving around hiking under tree cover, in a direction not pointing the panels toward the sun, in the rain, etc.
