Hi there Maine Sail. I have a small ranch in east texas and am looking to pump water, using a 12v pump and solar panel setup out of a creek from mid sept to november. I am needing to do this in dry years, I have a seasonal creek, which is about 22' deep and will need it to work when the season is dry and there is not much water moving in the creek. Do you think a 12v vein pump would do this or do you have any suggestions? I was thinking of using my 45 w of solar panel's coupled to a diesel truck deep cycle battery, 12 v float switch and one or 2 pumps (1000 gph or so), with flotation riding on a pipe concreted into the bottom of the creek with a larger ID pipe riding on the other pipe.
Any suggestions for me please? You are obviously a man that knows his pumps. No issues here in texas in removing water from a creek for irrigation of livestock.
