I have a good well In Central Texas that is used to provide water to my stock tank in times of drought. It uses a pump at 300' powered by a 220v generator when it is needed. I would like to convert to a solar pumping system using a Grundfos pump. My local well service company wants waaayyy more than my minister's salary can handle so I'd like to convert it myself. I'm confident working with solar panels and the wiring but know nothing about the well. Since I'm just replacing the AC pump with a DC Grundfos I'll assume that I can re-use the existing wiring, pipe and safety rope. Will there be more involved than hauling up the old pump and replacing it with the new one? Will one man be able to haul up 300' of water-filled pipe? Thanks in advance for any help you can offer.
