High-Performance Solar-Powered Water Pump

The solar water pump system is mainly composed of solar panels, controllers, water pumps, and connecting lines. Its working principle is based on the photoelectric effect. The solar panel is composed of a large number of photovoltaic cells. When sunlight shines on the panel, the photons interact with the semiconductor materials in the panel, so that the electrons gain enough energy to break free from the atomic bondage and form electron-hole pairs. These electrons and holes move in a directional manner under the action of the electric field inside the panel, generating direct current, realizing the conversion of solar energy to electrical energy. ​The controller plays a core regulatory role in the system. On the one hand, it monitors the voltage and current output by the solar panel to ensure that it is in a stable and appropriate range to prevent damage to the water pump due to excessively high or low voltage; on the other hand, the controller will accurately control the start, stop,…
