EcoRenovator - Newbie looking for a place to start

Howdy,

Figure this time has come to actually learn and move.
Live on 2 acres in a rural part of the west. Just wanted to do things with low or now impact. Started with an Archimedes Screw to lift water about 6' to a watering trough.
Looking at my home and want to try a few low cost solar projects before I start throwing panels on my roof.
I'll post in the appropriate forum but my first project is a solar exhaust fan (similar requirements of a bathroom fan) to keep fumes out of a work area. Not high demand just a small constant flow.
