I currently have a shallow (25 ft) well that is an excellent producer of very clear, very clean water. It runs on a Myers HC50 Jet pump with a 3/4 hp GE Motor. I am looking at trying to convert this to a solar pump w/ battery bank. I believe this could be done by replacing just the pump motor...not certain, as I am just starting my research. I have a 20 gallon pressure tank as well...may up the size of this. I am also considering adding a 400 gallon doorway tank for reserve water as well (there is room adjacent to the well pump and pressure tank in the utility/pump room in my basement). Thoughts, suggestions, advice?
