Tips: What is Solar Water Pump?
Solar water pump system is a photovoltaic pumping system that uses the solar panel power generated by the PV (photovoltaic) array to drive the pump. The whole system is mainly constituted by the solar panel, solar inverter and solar water pump. It is the most attractive water supply means in the sun-rich areas of the world today, especially in remote areas where electricity is insufficient or not available.
There are two main types of solar water pumps. The surface pump is located on the ground and moves water through the pipe. They can move a lot of water slowly. The submersible solar water pump is located underground, but the solar panel is connected on the ground. The submersible pump is used to move water from the well to the surface. Solar water pumps are often found on farms or large irrigation systems where water needs to be moved from the lake to the field for irrigation, or to be moved from the well to the water tank for fountain, pool and home use.
