Default pretty deep

They just finished drilling my well (and my wallet) and
I was wondering if anyone makes a solar well pump that can
draw water from 420'deep?

Any answers smart or dumb appreciated

Well, what voltage and current does your wellpump need? That will give
you your requirements. First guess is that you'll need an awfully large
solar system to do it.

How much are they charging these days? I paid $17.00 / foot back about
8 years ago.

Never! Max draw of ANY pump is 10 metres, water will start to boil at lower
pressures. The only thing to do is to install a pump down below.

I believe the Grundfos SQ Flex series could handle it. A bit beyond
the specs, but I think I've heard of them working to 500. There's the
Dankoff ETA as well. Both are very pricey though. If you don't need a
lot of water you could suffer the inefficiency of a standard AC
submersible (that's what we did), assuming your power system is up to
it. A 3/4 hp 5 gpm would be iffy, and only if going into storage. A 1
hp 5 could deliver about 4 gpm and 40 psi from 420 ft pumping level.
For more accurate info, post your well depth, static depth, daily
needs, how you intend to handle pressure, and what if anything you
have for solar power already.

He's saying it has to be pushed from the bottom rather than pulled
from the top, as you would with a hand-driven pump. But I don't
think "draw" was used to imply pulling from the top in this case.
