How to choose a solar water supply and return pump

How do you design a solar water pumping system?

When designing a solar pumping system, the designer must match the individual components together. A solar water pumping system consists of three major components: the solar array, pump controller and electric water pump (motor and pump) as shown in Figure 1.

How to choose a solar water pumping system?

The type of solar water pumping system: borehole/well (submerged), floating or surface will depend on the water source. If the source is a borehole (proposed or existing) or deep well, then a submersible pump that fits the borehole or well should be selected. If the water source is a river, then a surface pump should usually be selected.

What are the components of a solar water pumping system?

A solar water pumping system consists of three major components: the solar array, pump controller and electric water pump (motor and pump) as shown in Figure 1. Note: Motor and pump are typically directly connected by one shaft and viewed as one unit, however occasionally belts or gears may be used to interconnect the two shafts.

What is a solar pump system?

In this tutorial, we delve into the intricacies of designing a solar pump system, a sustainable solution harnessing solar energy for water pumping. Ideal for remote or off-grid locations, these systems are increasingly pivotal in modern agriculture, livestock management, and rural water supply.

Should you choose a solar water pump based on data sheets?

First of all, compared to traditional pumping systems, it’s not as straightforward to select a pump based on data sheets when you’re operating with solar water pumping systems. This is because the day profile is based on the sun – and as we all know, there are more hours of sun during the summer than during the winter.

What does a solar water pump manufacturer/supplier do?

solar water pump manufacture/supplier will have tables or computer software which specify the flow from the solar water pumping system for various heads and solar irradiation. The “solar water pump designer” shall be capable of: Using the manufacturers data sheets or software to select the most appropriate solar water pumping system.
