well, we will be bringing up small things that require power, even
if not large appliances. Anyway, "12 V" often means things are actually
14 volts or a bit more, depending on the circumstance, so the main
thing is really the rough scale we're talking about.

Solar panels generate about 1/2 volt DC per cell, so the structure
of any voltovoltaic arrays in use would determine input power to
the base distribution system. Though you'd expect all sorts of
batteries and other regulators in between to keep power levels
steady.
