Solar water pump (also known as photovoltaic water pump) is the most attractive water supply method in the sun-rich areas in the world, especially in remote areas without electricity and no electricity. It is an ideal green energy system that integrates economy, reliability and environmental benefits.

The system composition

1. Photovoltaic array

It mainly converts sunshine energy into electric energy, so it provides working power to the load pump motor.

2. Photovoltaic pumping inverter or controller

The operation of the solar water pump is controlled and adjusted, the water pump is driven by the electric energy emitted by the solar array, and the output frequency is adjusted in real time according to the change of the sunlight intensity, so that the output power is close to the maximum power of the solar battery array.

3. Motor (drive motor)

The drive motors used in different systems are also different. In the photovoltaic water pump system with a power level of less than 10Np, in order to obtain the highest system efficiency as possible, DC brushless permanent magnet motors are mostly used for driving. With the continuous development of technology, in order to further increase the water lift provided by the unit peak watt, it has begun to be replaced by the multi-machine group control technology that realizes flexible control of multiple pumps.

For the photovoltaic pump system, the selection of the pump type is also very important. In a system with low power, if the user requires a high lift but a small flow, a positive displacement pump should be selected. In other cases, a centrifugal or axial flow pump may be used.The selection and consideration of pump types for photovoltaic water pump systems.

5. Water towers and water storage facilities

If the photovoltaic water pump system is used in cold winter regions (such as the vast western region of China), it is advisable to use antifreeze water storage facilities, such as intermediate vacuuming or double-layer water tanks or water towers with thermal insulation materials and antifreeze treatment.

Its advantages:

1. High reliability, photovoltaic power supply rarely uses moving parts and works reliably.

2. Safe, no noise, no other public hazards. Does not produce any solid, liquid and gaseous harmful substances, absolutely environmentally friendly.

3. Simple installation and maintenance, low operating cost, suitable for unattended operation, etc. In particular, it has attracted attention for its high reliability.

4. Good compatibility, photovoltaic power generation can be used in conjunction with other energy sources, and the photovoltaic system can be easily expanded according to needs.

5. The degree of standardization is high, and the components can be connected in series and parallel to meet the needs of different electricity consumption, and the versatility is strong.

6. Solar energy is everywhere and has a wide range of applications.
