Solar PV Water Pumping System

  • 2022-01-26 17:06:44

The basic principle of "PV Water Pumping System", also called "Solar PV Water Pumping System", is to use solar cells to directly convert solar energy into electrical energy, and then drive all kinds of motors to drive the water pump to carry water from deep wells, rivers, lakes, ponds and other water sources. It has many advantages such as no noise, fully automatic and high reliability, and good adaptability of water supply and evaporation volume. Its main component functions include:

a.Photovoltaic array

It consists of multiple solar cell modules connected in series and parallel, absorbing sunlight radiation energy, converting it into electrical energy, i.e. solar power generation, and providing power supply for the whole system. Most of the solar cells currently used in PV water pumping systems are silicon solar cells, including mono-crystalline silicon, poly-crystalline silicon and amorphous silicon solar cells.

b.Photovoltaic controller

Photovoltaic array output and solar irradiance, ambient temperature, cloudy, sunny, rainy, foggy and other meteorological conditions are closely related. PV pumping system work in a more ideal condition, are to play the maximum potential of photovoltaic array output power, which requires an adapter, so that between the electric rib load can reach an efficient and stable working condition. The content of the adapter is mainly the maximum power "point tracker, inverter and some protection facilities.

c.Water Pump

Water from deep wells or rivers, lakes and other water sources, injected into the off grid water pump, 3’’DC brushless solar powered with S/S impeller water pump, DC Submersible Pump, solar deep well pump with internal controller for irrigation pump, or directly connected to fountain systems, etc. can be used.


For a long time, how to solve the water supply in mountainous areas, dry areas, grassland pastures and desertification areas at the energy level has been a technical problem plaguing the development of agriculture and animal husbandry and ecological construction at home and abroad. In recent years, PV water pumping system caters to the large-scale demand market of farmland, grassland and desert, and can be widely used in remote areas without electricity and lack of electricity for water supply for human and livestock, farmland irrigation and desert management.



The system can be used flexibly without any external energy for irrigation of farmland, providing clean drinking water, beautifying the park, constructing colorful fountains, adding oxygen to fish and shrimp ponds, and supplying and draining water to seaside salt fields. And the application of solar water pumping system without battery, save the cost of battery replacement, reduce the pollution caused by the battery to the environment, in line with the strategy of sustainable development in China.
