How Much Water Will a Solar Pump Produce in a Day?

A solar pump only runs while the sun is on the panels, so we look at gallons per day and not just gallons per minute. Take the pump’s flow rate and multiply it by your pumping hours. In most of the Southwest that is about 6 hours in summer and closer to 4 in the middle of winter.

Our SDS-T-128 at 230 feet of head produces about 1.5 gallons per minute. That is roughly 500 gallons on a summer day and about 350 in winter. Our HR-5-750 at 750 feet runs about 5 gallons per minute, or around 1,800 gallons a day in summer and 1,200 in winter. The HR-12-328 at 300 feet runs about 10 gallons per minute, which is 3,600 gallons a day in summer and about 2,400 in winter.

These are some of the most common systems we deliver, but much more is possible. Current technology allows us to run just about anything. We just have to power it. That means the higher the horsepower on your motor, the larger your solar array gets.
