Tips: How does solar water pump work?
The main difference between the solar water pump and the conventional water pump is the power source. The solar water pump relies on the solar panel as power supply to operate. The solar panel can be built into the device or it is an independent structure that is connected to the pump by wires. Afterwards, the solar panel supplies power to the pump, making it work independently of any existing electrical system.
Using the power generated by the solar cell, the brushless DC motor or the high-efficiency asynchronous motor inside the solar water pump is driven by the maximum power point tracking (MPPT), and solar pump inverter and controller to drive the water from the well to the ground for agricultural irrigation or human and animal drinking.
