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.

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 water pump?

A solar water pump theoretically consists of three key components: a pump control system that may be just an on-off switch or may be a more complex electronic unit, a motor and the pump; however, in practice they are considered as one unit and generally called the “water pump” or in this guideline the “solar water pump”.

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.

How to install a solar pumping system?

The installation of the electrical components should be performed according to all applicable standards and the manufacturer’s instructions. Many solar pumping system packages will include solar modules with interconnecting cables/ connectors set up for ‘plug and play’ by using plug and socket connectors.

How do I sizing my solar water pumping system?

Some manufacturers provide sizing software online to assist individuals/communities to select the most appropriate solar water pumping system. This section of the guideline provides some examples. On that screen select: Sizing (in blue) and then “Advanced sizing by application” and select “solar water solutions”.
