And once you have your power infrastructure setup its fairly easy to add
solar to augment it. I just keep an eye out for a good deal and add a
panel when I can.

Solar is already a reality, but it is poor in the winter, thus the
hydro venture.
Quick question.... This alternator has a couple windings on it. It
has the main windings, and the spark power source. Then it has two
coils that are devoted to producing 12 v at 8 amps for battery
charging. If I opt not to use the extra windings, should I place a
dummy load on those coils to keep them from overloading, or would that
place an extra strain on the alternator thus reducing the output.
Should I just totally eliminate them and remove the windings? What do
you guys think?

I think you should just leave the redundant coils disconnected. You may find
a need for them in the future, particularly those 12 volt coils. If the extra
coils have no current through them, they can not overload and will not place any
strain on the alternator nor take any power from your prime mover.

Vaughn is right here, BUT you should make sure that you isolate the
windings with Good High Insolation Tape, as they will have a significant
voltage on them when the alternator is spinning, and you don't want them
to arc, or short.

"High Insolation"? Only for a solar power setup.
