badge53 welcome to PB.
awesome post bruce.
i am just beginning to look into a solar powered pump set up for a well that i havent drilled yet......you can see this is gonna be a lot of help to you
anyway, i am waiting to hear back from a guy (an electrical contractor i met) who told me of a system that runs about $3,500. its a solar cell and battery system that can reportedly do 25,000 gallons a day, which translates to roughly 17 gpm. thats probably on the low side of what you need, but would suit me just fine. Some of my questions on this system? I dont know the max HP pump it can run, nor from how deep it can pull. I'll try and remember to report back here with more detailed info if interested.
