Depending on how efficiently and well it works, it could be anywhere from 10 to 40 watts. A good inverter transforms more sunlight into electricity, requiring less extra power. . A solar water pump sizing calculator is an online tool that estimates: Pump power (Watts) → how much energy your pump needs. Battery capacity (Amp-hours) → storage needed to keep water flowing during cloudy days. Daily energy use. . The pump has a running wattage of 500W and a starting wattage of 1000W. 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. . A single solar inverter can deploy about 40 watts when it is not working or at night. Whether you have a house or run a business, considering this is important to make the most out of your solar panel systems.
