PV arrays
It mainly converts the sun's light energy into electrical energy to provide working power for the load pump motor.
PV water inverter or controller
Control and regulate the operation of the solar water pump, drive the pump with the electric energy emitted 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.
Motor (drive motor)
The drive motors used in different systems are also different. In the photovoltaic water pump system with less than 10 Np power level, in order to obtain the highest possible system efficiency, more use of DC brushless permanent magnet motor drive, in the large-scale photovoltaic water pump system, there is still no lack of AC asynchronous transmission mode, but due to the continuous development of modern control technology, in order to further improve the amount of water provided by the unit peak tile, it has begun to be replaced by multiple pumps to achieve flexible control of multi-machine group control technology.
Water Pump
For photovoltaic pump systems, the choice of pump type is also crucial. In the system with low power, if the user requires a high head but a small flow, it is advisable to choose a positive displacement pump, and in other cases a centrifugal or axial flow pump may be used. About the selection and consideration of pump type for photovoltaic water pump system.
Water towers and water storage facilities
If the photovoltaic water pump system is used in cold winter areas (such as the vast western region of China), it is advisable to use antifreeze water storage facilities, such as intermediate vacuum or double-layer water tanks or water towers with thermal insulation materials, and the water diversion pipeline should also use low-temperature resistant materials and antifreeze treatment.
