We used a couple of them for years, but they were the vibrating type of motor. In shallow wells, they would pump 2-4 gallons a minute, That was enough to water quite a bunch of cattle. A wire placed in the tank would shut to pump off when the tank was full.
Since then, they have come out with a submersible pump which pumps a lot more water and is more reliable. Our neighbors have a solar system backed up by a windcharger. They pump the water into a pipeline and it waters a herd of 3-400 cows. I noticed last week they had the windcharger shut off and it was working solely on solar - and doing a good job.
We quit using ours because of water quality (neighbors have the same problem) and we put in several miles of pipeline and pump good water from the sand next to the creek.
Winter is not a problem - just put a small drain hole near the frost line and when the suns goes down, the pump stops and the water drains back to below the frost line.
We would have upgraded to submersible pumps if the water had been good enough for cattle.
It takes quite a bit of solar panel surface to pump against pipeline pressure but it just a matter of adding panels, A 2 X 4 foot panel makes about 75 watts so that 8 or 10 pannels hooked up would pump water most anywhere. My guess is that there are some outfits that could pump water from 1000 feet deep. It wouldn't be cheap.
We were running generators 24 hours a day all summer for a while, but we finally built the pipeline. (A state highway road project provided some excess money which we used for the pipeline.)
P. S. Does the sun even shine in the winter there?
