Magadan solar water pump application range

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.

Introduction of Solar Water Pumping Systems (SWPS) Pumping water is a universal need around the world and the use of photovoltaic power is increasing for this application. A solar powered pump is a pump running on the power of the sun. A solar powered pump can be very environmentally friendly and economical in its operation.

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.

The chosen design demand will form the basis of the design of the rest of the system. It is critical to the success of a completed solar powered water system that the design demand be clearly stated and agreed upon by all parties involved in the planning and future ownership of the system, including documentation of the agreement.

Other economic parameters for instance, benefit cost ratio of 1.6 and internal rate of return of 18.15 % mark favorable to invest for the system. In addition, the solar water pumping system is compared with grid-electric pumping system. The cost of a pumping system operated by grid electricity includes the cost of feasible grid extension.
