Therefore, new energy sources such as solar energy and wind energy are widely used, and they are inexhaustible and inexhaustible. The working principle of the photovoltaic water pump system is to use the voltaic effect generated by photovoltaics to directly convert solar energy into electrical energy, and then drive the motor through the controller to drive the pump to pump water. The photovoltaic water pump system works at sunrise and rests at sunset, and is unattended. It has the advantages of low energy consumption, resource conservation, and convenient use. At the same time, it can effectively achieve the goals of energy saving, water saving, agricultural production, and income increase. One of the development directions of the platoon.
在实际运行时，长时间的光照辐射会使太阳能电池板内部温度升高，光电转换效率下降，另一方面光伏电池板在室外使用，日积月累的灰尘使得太阳光透射到电池板表面的效率降低，最终均会使光伏水泵的出水量大幅减少。因此，为了提高光伏水泵的出水量，就必须提高太阳能电池板的光电转换效率。In actual operation, long-term light radiation will increase the internal temperature of the solar panel and reduce the photoelectric conversion efficiency. On the other hand, when the photovoltaic panel is used outdoors, the accumulated dust will reduce the efficiency of sunlight transmitted to the surface of the panel. In the end, the water output of the photovoltaic water pump will be greatly reduced. Therefore, in order to increase the water output of the photovoltaic water pump, it is necessary to increase the photoelectric conversion efficiency of the solar panel.
