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.

How to choose the rated power of a solar pump inverter?

When choosing the rated power of a solar pump inverter, you need to consider the following factors: Power demand of the water pump: First, you need to understand the rated power of the water pump used.

Should 13000 litres (3434 gallons) be used for solar water pumping?

So, should 13m3 or 13000 litres (3434 gallons) @ irradiation of 5.4kWh/m2 be used for selecting a solar water pumping system or should 10 m3 (or 2642 gallons) @ irradiation of 4.38 kWh/m2 be used? In reality both could be used and it is possible that the same system would be selected for both. If this is the case, then the array

What size water pipe should a solar water pumping system use?

The designer should initially use pipe that is the same size as the inlets and outlets. The designer then undertakes the frictional loss calculations for that size of water pipes using the known maximum water flow for that solar water pumping system.

How much water can a 200W Solar System provide?

Referring to Table 7a, the 200W solar system can provide 14 m3 with a head of 20 metres using a tracking solar system. Using a stationary array frame this will produce 0.77 x 14m3 = 10.78m3. This system should meet the requirement of providing a minimum of 9 m3 of water per day. From Figure 13 it can be seen that the pump to
