The solar pumping system is mainly composed of photovoltaic modules, solar pump controller/inverter and water pump, the solar panel converts the sunlight into electrical energy, passes it to the solar pump controller, the solar controller stabilizes the voltage and output power to drive the pump motor, even on cloudy days, it can pump 10% of the water flow every day. The sensor is also connected to the controller to protect the pump from running dry and automatically stop the pump when the tank is full.
