Non-pressure solar water pump selection

Velocity head at the beginning and end of pump. Using the manufacturers data sheets or software to select the most appropriate solar water pumping system. The total dynamic head. The solar water pump manufacture will provide information on the solar water pumping system performance for various heads and solar irradiation.

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.

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.

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”.

There are many possible applications for solar water pumping, especially when considering that the pump can be combined with energy storage or other types of generation to make it more versatile. However, this guideline is related to solar only systems.

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.
