There are 400w panels out that are roughly 7'x3.5' So a rather
reasonable 7'x7' trailer could produce 800w, which is a good amount of
power - but not nearly enough.
Assuming they're mounted flat, that's 800w at high noon, and less at
every other part of the day. We could expect something like 3.2kwh /
day of production, or roughly a 1 mile extension in range.
To get the 12kw needed, we need at least 15 times that, or 105' long
trailer, 7' wide. Then we could drive continuously at around the noon
hour for around an hour, on a good sunny day.
Sadly, as you said, it's a math problem..

The math problem here is consumption over time. A solar racer with a 5
passenger capacity 850 pound weight with a coefficient of drag of .16 rolling
on moped wheels with a 1.5kw panel and 15kw battery can attain 45mph
continuously without using battery power. A Nissan Leaf going 55mph achieving 5
miles per kwh would(if I got my math right) need 12kw continuously to keep that
speed in full sunlight. Of course the battery is a buffer that will allow you
to do faster speeds and climb hills. I suspect some sort of Pop tent trailer
might be a good combination for the Cyber Truck. 450.5 sq. ft. is the maximum
size of a trailer. A pop tent that size would be quite a mansion. However that
might only produce 5 to 6kw. Enough to charge and extend but not to run
continuously. Weight must be reduced and coefficient of drag lowered. It's a
math problem. Lawrence Rhodes
