Bishkek solar water pump application scenario

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.

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.

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.

Thus, one al-ternative to conventional electricity and diesel- based pumping systems might be the use of solar energy for water pumping. Solar energy could therefore be a viable water pumping alternative to traditional electricity and diesel-based pumping systems.

Solar photovoltaic water pumping systems offer cost-effective and sustainable water access, aligning with global goals to reduce carbon footprints and enhance rural resilience to climate change . In the context of water management, renewable energy systems like PV have gained traction as viable alternatives to fossil fuel-based power sources.

Based on a tilt angle of 18 degrees, the lowest ratio is 0.438 so June will be the design month. If this is finalised as the design month, the solar water pumping system must then be selected based on an irradiation of 4.38kWh/m2 and the required flow of 10 m3 or 10000 litres (2,642 gallons). angle. This is shown in Table 12
