Solar-powered Water Pumping Unit

Working principle and advantages of solar water pump based on traditional photovoltaic technologyWorking principleThis solar water pump uses traditional photovoltaic panels as energy collection units. Photovoltaic panels are composed of numerous photovoltaic cells. When sunlight shines on photovoltaic cells, photons interact with semiconductor materials in the cells to generate electron-hole pairs. Under the action of the electric field inside the battery, electrons and holes move in opposite directions, respectively, forming current and generating direct current. Direct current is transmitted to the controller through wires. The main function of the controller is to regulate the current and voltage and convert unstable direct current into stable electrical energy suitable for water pump operation. The water pump is usually a DC pump or an AC pump driven by an inverter after being converted into AC. After receiving electrical energy, the motor inside the water pump starts to run, drivi…
