Solar water pump system composition

Photovoltaic array
It is mainly to convert the light energy of the sun into electrical energy to provide working power for the load pump motor.
Photovoltaic water inverter or controller
The operation of the solar water pump is controlled and adjusted, the electric energy emitted by the solar array is used to drive the water pump, and the output frequency is adjusted in real time according to the change of sunshine intensity, so that the output power is close to the maximum power of the solar battery array.
Motor (drive motor)
The drive motors used in different systems are also different. In the PV pump system with less than 10 Np power levels, in order to obtain the highest system efficiency as possible, most of the brushless DC permanent magnet motor is used to drive, in the large-scale photovoltaic pump system, there is still no lack of AC asynchronous transmission, but due to the continuous development of modern control technology, in order to further improve the water lift provided by the unit peak watt, has begun to be realized by multiple pumps Flexible control of multi-machine group control technology to replace the trend.
Water pump
For photovoltaic pump systems, the choice of pump type is also important. In a system with low power, if the user requires a high head but a small flow, it is appropriate to choose a positive displacement pump, and in other cases it may be possible to use centrifugal or axial flow pumps. The selection and consideration of pump type for photovoltaic pump system.
Water tower and water storage facilities
If the photovoltaic pump system is used in cold areas in winter (such as the vast western region of China), it is appropriate to use antifreeze water storage facilities, such as double-layer water tanks or water towers with vacuum or insulation materials in the middle, and the water pipeline should also use anti-low temperature materials and anti-freeze treatment.
