Since you're not going to realistically get enough power from solar to power the whole thing, I'd think you'd be better off skipping batteries and powering motors directly from the solar array, when sunlight is available, to supplement the main engines. Whether or not the fuel savings would be enough to be worth bothering with is the real question.
