How much wattage does a solar water pump need?

Let's say you want to pump water from a depth of 50 feet at a rate of 5 GPM using a 12V pump that is 70% efficient. The region receives an average of 6 hours of sunlight per day, and you want to use a 12V solar panel and battery. Using the Solar Water Pump Sizing Calculator, the minimum solar panel wattage required is calculated as follows:

What is a solar water pump sizing calculator?

The Solar Water Pump Sizing Calculator is an essential tool for individuals who rely on solar power to pump water. By providing the required input data, users can accurately calculate the minimum solar panel wattage and battery capacity required to meet their water pumping needs.

How do I choose a solar panel for my water pump?

The power requirement of your water pump is one of the most critical factors in determining the type of solar panel you need. The power requirement is usually measured in watts (W) and depends on factors such as: Pump Capacity: The amount of water you need to pump per day.
