Solar pumps are increasingly becoming popular in rural and remote areas where access to the main grid is limited or non-existent. These pumps are powered by photovoltaic panels that convert solar energy into electrical energy, which is then used to run the pump. The pumps come in various sizes and capacities to cater to different needs, such as irrigation, drinking water, and livestock watering. EDWIN PUMP has developed a wide range of solar pumps, from 2" to 6" in size, and power from 0.2KW to bigger. Customers can also choose screw type or impeller type. For impeller type, we can supply both plastic material and stainless steel material. The pump head can reach a maximum of more than 300 meters. One of the key advantages of solar pumps is that they are environmentally friendly. Unlike traditional pumps that run on fossil fuels, solar pumps do not emit any harmful pollutants into the atmosphere. They also do not produce any noise, making them ideal for use in quiet rural areas. Furthermore, the cost of operating a solar pump is significantly lower compared to traditional pumps, as there is no need to purchase and transport fuel. Another benefit of solar pumps is that they are relatively easy to install and maintain. In many cases, the pumps can be installed by local technicians with minimal training, reducing the need for expensive and time-consuming installations by outside technicians. In addition, the pumps require little maintenance, as there are no moving parts that wear out over time. However, there are also some limitations to using solar pumps. One of the main limitations is that they require access to sunlight in order to operate effectively. This can be a problem in areas with long periods of cloud cover or heavy rainfall. In addition, the cost of purchasing a solar pump can be relatively high, especially for larger and more powerful pumps. This can be a barrier for communities that are already struggling with limited financial resources. To solve these problems, EDWIN PUMP developed the AC/DC solar pump, DC can be used when sunlight is strong and AC can be used when the sunlight is lacking. If the sunlight is always strong, people can just choose the DC solar pump, because it can save a lot of cost on the pump.
