I agree what others said, without full direct sun and being stationary long enough it is a wash compared to just bringing a larger battery bank.
When I was doing my research this panel was the best for output Vs weight.

Pretty much everyone asks this same question at some point in their planning. And you only are confident in the result after you ask it yourself.
I only saw one person with a solar rig. They were one of the 10lb-11lb base weight people -- Superheros? Freaks?...we still don't know; we just respect them -- and they carried this Lixada panel. They only got ~5W-7.5W out of it, at best, but it was reliable.
The issue they said was getting sufficient sunlight relative to their phone useage. They knew they could manage in some sections but were going to swap for a power bank in others.
And, as you've sorta discovered, and as most people do, ya...you could curtail your electronics use to work within that bottleneck of a solar rig <or>...you could carry a reasonably light power bank.
The Nitecore 10000 and Anker Powerline Slim PD 10000 are some common favorites.
I use the Lixada solar panel (98g / 3.5oz) with the Nitecore 10,000mAh power bank (154g / 5.4oz). I attach the solar panel to the corners at the top of my backpack's mesh pouch. My tent is stuffed into the pouch, so the "hump" creates a pretty good angle to capture the sun. I secure the bottom two corners to the rings below my mesh pouch using a piece of 1/16" shock cord. (It's just enough to keep the panel from bouncing around or getting blown upwards by the wind.)
I charge my electronics from the power bank at night. The solar panel keeps the power bank topped off if I hike in the sun the next day. And on cloudy/shaded days, well, that's why I have 10,000mAh as a buffer.
I rarely need to charge my power bank in town. Finding an outlet is one less thing I need to deal with.
Depending on what you're looking for, here's a few things I've gotten from Amazon over the years and have had good experiences with them:
Most of these are more luxury and lightweight than true ultralight - but these are some of the things I've gotten some enjoyment from. Your mileage may vary.
