Technical FAQs 4

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.

What information do I need to size a solar pump system?

The generated PDF is a great way to share your selection with colleagues or clients. That just about covers it. In short, all the information we need to size a solar pump system at Grundfos.com is the project’s location, the flow per day, the static lift and the dynamic water level.

What is the minimum battery capacity required for a solar water pump?

The minimum battery capacity required to store the energy generated by the solar panel can be calculated as follows: Battery Capacity = (2.34 x 6) / 12 = 1.17 Therefore, the minimum battery capacity required is 1.17 Ah. The Solar Water Pump Sizing Calculator is an essential tool for individuals who rely on solar power to pump water.
