Solar photovoltaic water pump system, also known as solar photovoltaic water system, as the name implies, is a kind of equipment for pumping water supply through solar power generation using water pumps, it is mainly composed of solar battery packs, solar water inverters or controllers, water pumps, and its application scenarios are very extensive, such as photovoltaic drought resistance, desert greening, desert management, grassland animal husbandry, agricultural irrigation, desalination, etc.
Its working principle is not complicated, that is, through the solar panel absorption of light energy into electrical energy to provide power for the entire system, and then the water inverter converts direct current into alternating current to drive the pump, and finally pumps the water from the deep well into the reservoir or directly connected to the irrigation system. Due to the characteristics of solar power supply, solar photovoltaic water pump systems are an attractive means of water supply for remote areas that lack electricity and no electricity.
In addition, in the application of water pump is divided into motor brushless DC water pump, brushless DC magnetic isolation water pump, three-phase AC water pump three, a kind of water pump has been standardized, with low cost, high efficiency characteristics, its disadvantage is that after a long time of use there will be a risk of motor burnout; The second type of water pump is characterized by small size, long life, low noise, etc., and can also be used for hot water circulation; One is different from the DC system, its advantage is strong compatibility, mostly used for large-scale farmland irrigation, desert treatment, etc.
In general, the solar photovoltaic pump system has the characteristics of safety and reliability, energy saving and environmental protection, high degree of standardization, simple installation and maintenance, strong compatibility, and can also achieve unattended, fully automatic operation, etc., its development prospects are very broad, for the future development of the economy, especially the development of arid areas, remote areas of the agricultural economy, in line with China's sustainable development strategy, but also can bring huge economic benefits.
