That means you would need three 250 watt solar panels to produce the minimum amount of energy to run the pump. . The number of solar panels required for water pumps varies according to pump size and specifications. Battery capacity (Amp-hours) → storage needed to keep water flowing during cloudy days. For example, a 1000W pump requires at least 1500W of solar panels. For example, if your submersible water pump requires 1000 watts to operate and you get an average of 5 sunlight hours daily, you'll need around 200 watts × 5. . These pumps are slightly more efficient and can run on anywhere from 200 watts (two 100-watt panels) to around 800 or 1,200 watts of power.
