While I would agree with the OP, that 3 phase AC pumps are a better solution than 120 or 240VAC single phase, I think that DC submersibles are an even better solution. There are a few out there but the worm pump mechanism ones with controller at the surface seem to offer much more efficiency, ability to change setup params, and serviceability.
I have been using such a DC pump in my well for a bit over 3 years. I got two used 160W 24v (72 cell) panels to power it, and it has worked well for us so far. With some AGM batts, it can pump overnight and refill the cistern after a day of heavy water use. I also especially like the ability to dial the speed of pumping up/down at the controller. This allowed me to match the pump speed to my well's recovery rate, so that it rarely hits a well low condition; more efficient use of power and actually higher overall pump volume per time.
I may change my mind if something bad happens in the future with this setup, but as of now I would never go back to an AC pump.
