I have query about some solar power water pumps. There is a river near my house. And I am planning to get water from that river into my yard and garden. I want the pump to pull water out of the river into my garden and yard area. So I am looking for some water pump for my sprinkler. Can somebody help me with some places where I can get this solar power water pump for my sprinkler? Also can somebody explain is it better to use solar powered water pumps instead of conventional water pump which uses electricity? Waiting for your replies. Thanks.
