Features of solar photovoltaic water pump

Solar photovoltaic water pump is also called photovoltaic water pump. It is a photovoltaic water pumping system that uses the electricity generated by the photovoltaic array to drive the water pump. The whole system is mainly composed of photovoltaic array, solar water pumping inverter and water pump. It is an optomechanical and electrical integrated system that has developed rapidly in recent years. It is the most attractive water supply method in the world's sunshine-rich areas, especially in remote areas with electricity shortages.

1. System composition:

1. Photovoltaic array: also known as solar cell module, it mainly converts solar light energy into electrical energy to provide working power for the load water pump motor.

2. Solar water pumping inverter or controller: control and regulate the operation of solar water pump, drive the water pump with the electricity generated by the solar array, and adjust the output frequency in real time according to the change of sunshine intensity, so that the output power is close to the maximum power of the solar array.

3. Water pump: usually lift liquid, transport liquid or increase the pressure of liquid, that is, convert the mechanical energy of the prime mover into liquid energy, so as to achieve the purpose of pumping liquid. Machines are collectively referred to as pumps.

2. Operation process:

Using the power generated by solar cells, the DC, permanent magnet, brushless, position sensor-free, stator-rotor double plastic-encapsulated motor or high-efficiency asynchronous motor or high-speed switched reluctance motor is driven to drive high-efficiency water pumps through maximum power point tracking, conversion, control and other devices to lift water from deep on the surface to the ground for farmland irrigation or drinking for people and livestock.

3. Advantages:

1. Reliability: long life, photovoltaic power supply rarely uses moving parts, and works reliably;

2. Safe, noiseless, low power consumption, and no other pollution. It does not produce any solid, liquid and gaseous harmful substances, and is absolutely environmentally friendly;

3. Simple installation and maintenance, suitable for unattended operation, especially 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 as needed;

5. High degree of standardization, components can be connected in series and parallel to meet the needs of different electricity consumption, and it has strong versatility;

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

7. It has good long-term economic performance, especially compared with the common diesel engine pumping, it has an overwhelming economic advantage.
