Natural Energy Research Institute of Gansu Academy of Sciences, the solar power plant, the successful application of pumping equipment, developed a solar photovoltaic pump for agricultural irrigation in the northwest mountain to solve the power problem. At present, the four sets of solar photovoltaic pump prototypes have been tested and tested in operation. The technical performance of the four prototypes has reached the design targets. Two of them have been put into operation in Dingxi, Gansu Province. The next step will be industrialized production and promotion. Solar cells in the light energy into electrical energy devices called photovoltaic devices, solar photovoltaic pump is the use of electricity generated by photovoltaic devices as a common submersible pump power supply, pumping irrigation operations, it will solar and submersible pump these two devices successfully To combine together. This pump has three advantages: First, easy to install, can be placed in the trolley, easy to move; Second, long life, a solar panel life of up to 25 years, one-time investment, you can use for a long time; Third It saves energy, it only needs sunshine, does not need to consume any conventional energy, abundant sunshine in the northwest mountain area and abundant solar energy are the ideal areas for using this kind of water pump. For a long time, the problem of drought and lack of water has restricted the development of agricultural production and rural economy in northwest mountainous areas. In recent years, with the construction of small water conservancy projects such as rainwater harvesting projects, the mountainous areas in northwestern China have been developing rapidly in search of water resources. However, Lack of infrastructure and electricity bills are overburdened. The power issue has become a major challenge for agricultural irrigation in these areas. The successful development of solar photovoltaic pumps has enabled the abundant use of solar energy in mountainous areas in the northwest and provided a solution to this problem.
