Solar-powered sprinkler pumps, also known as photovoltaic water pumps or solar photovoltaic water pump systems, are green water supply equipment that uses solar energy to drive water pumps for water lifting operations. They are widely used in agricultural sprinkler irrigation, drinking water for humans and livestock, and desertification control. Their core principle is to directly convert solar energy into electrical energy to drive the water pump, eliminating the need for batteries or mains power. They achieve fully automatic operation by "using water storage instead of electricity storage."

Solar irrigation systems are devices that utilize solar energy for irrigation. They mainly consist of solar panels, water pumps, water pipes, and irrigation equipment. The solar panels convert solar energy into electrical energy, which is then stored in a battery system for use as power for subsequent operations. When solar energy is abundant, the system automatically starts the water pump, pumping water from the water source to the farmland requiring irrigation. Irrigation equipment is typically a specially designed system, such as drip irrigation or sprinkler irrigation. These systems can reduce water and energy consumption to a certain extent.
