I stumbled onto this a few minutes ago and I like the idea:

The biggest awning is 16 foot long and is rated at 1200 watts. I've managed to work out putting 865 watts on the roof of my TT already while still having some room to walk and something like this could put me over the top. From what I read the awning length can be reduced to 13 and 10 feet with 1000 and 800 watts respectively.
I am curious what the system weighs though as I have limited cargo weight to work with. I may abandon the roof system (other than the stock panel) and just do a solar awning. Unless it's just too heavy.
It's not going to be available until 2023.
