What Size Solar Pump Do I Need for a 300-Foot Well?

The short answer
I would answer this by saying it’s not so much about size as it is about performance. If a 300-foot well has a static water level around 180 feet, that is the depth you actually have to overcome, plus any additional lift uphill or rise into a tank. Your total head is the vertical lift from your standing water level to the outlet, plus friction loss from the pipe. At this lift range, many ranchers would choose our SDS-T-128 or our HR-5-400. The main differences for the user are going to be power requirements and the amount of water each pump can produce. At this head, we have many options to choose from, depending mostly on how much water is needed.
