Manufacturing capabilities are quite lacking, though, in the short and medium terms, so this doesn't seem all that relevant.

Maybe a self-contained, modular solar panel / radiator / compute unit could be built, but it will be manufactured on Earth. (Where the fabs are.)

And it still seems easier to put solar panels and batteries near the data centers that SpaceX is already building on Earth.
