I think I can help with that as we've been doing it for a couple of years.

First, how deep is the well and how much head do you need to overcome to bring the water to your reciever? A tank, usually.

Amarinemade is the least expensive and pretty dependable solar pump. And you can get solar panels off of ebay pretty inexpensively yet.

So, find out the dynamics of your situation. Then look, and pretty quickly in this scenario we are faced with, on ebay and Amazon for a pump that will fit the bill. Then make sure you can get a catchment into position to hold your water. Get the panels needed and oversize that array by at least 25%. Get the pump...And enjoy!

We have one back up pump...Coz you have to.

If you want to pump when you want instead of when the Sun shines only, you will need a battery bank, a charge controller and the pump and catch tank.

It's doable, but it takes a fair amount of thinking through things.
