Don't even think of pumping water with solar power. (A wind mill is pretty efficient at pumping water. Storing water is a lot cheaper than storing electricity.

I wouldn't even generate power for doing this. It has too many steps. Windmill -> generator -> battery -> inverter ->pump each with its inefficiencies.

Depending on your situation, you can either use a conventional windmill directly over the well and use a mechanical linkage, or you can use a windmill that pumps air and use an air lift. (Do a search for pond aeration windmill. Most of them have options for water pumping as well as aeration.)

My well pump is 1/2 horse. It draws 5 amps at 220 volts or 1100 watts. This is major power for a solar array. During the summer we use about 300 KwHr/month pumping water.
