Not really, it wouldn't even be feasible to replace the on-board electric with solar, ignoring propulsion. Using the information from here[1] it has five generators. One generator produces 4308kVA, and one of these [2] solar panels produces 0.296 kVA. So ~15,000 solar panels to replace one (of five) generator.

Thanks for the info. Hopefully future breakthroughs can change this math substantially.

They can't, these solar panels are probably not much more than 20% efficient, so even an extra factor of five doesn't make a dent.
