I think I just invented a new class of spacecraft in the shower. It's got enough surplus electric power output and payload margin that you can add Hall thrusters or a plasma magnet sail for supplementary acceleration, and requires no onboard nuclear power. Hell, inside the Belt it requires nothing but the sun and some LH2.

I call it the ArcMoth.

To make an ArcMoth, you start with a regular old Solar Moth design like pic related, using concentrated sunlight to heat LH2 up to a few thousand degrees and kick it out the back of your rocket.
