I want to build an off grid system. I am thinking of a combination of wind, solar, and would like to add micro hydro to charge a battery bank, then power the house.
But I do not have any water on the property. What I do have is a hill and the will! So is it possible to simply dig a pond up on the hill, or even use a 5000 gallon cistern to collect rain water, run it down the hill to a micro hydro turbine? How does one measure the head and flow that such a thing would provide?
