If you do the maths - those solar panels will help you not at all. Consider those ultralight, tiny solar racers they use across the desert each year in that uni race here in AUS.
They can run on solar using the entire upper surface covered in expensive high efficiency solar panels. Bugger all wEIGHT to speak of - ONE PERSON, no luggage, no lights, no air con, no... etc
So that's a no go with current tech.
As for the RIVIAN - hell yeah !
