Summary
Introduction to the core components of DIFFUL solar water pump
The basic principle of a solar water pump is to convert solar energy into electricity, which drives a motor to pump water. It offers advantages such as being silent, fully automatic, and highly reliable. Thanks to the synergistic effects of its core components, it can become an ideal green energy system that combines economy, reliability, and environmental protection.
Solar panels include monocrystalline silicon, polycrystalline silicon, and thin-film photovoltaic cells. Monocrystalline silicon solar panels have the highest power generation efficiency and are also the most expensive, followed by polycrystalline silicon and thin-film photovoltaic cells. Their nominal power output is generally around 150 watts per square meter. Solar panels are typically categorized by operating voltage, with options such as 48V, 72V, and 110V. The voltage also varies with temperature and varies from location to location; as the temperature rises, the voltage drops.
Water pumps include deep well pumps, submersible pumps, and centrifugal pumps. The key performance indicators for water pumps are head and flow rate. Due to the instability of sunlight, solar water pumps cannot be calibrated for rated head and flow rate; only maximum flow rate and maximum head are calibrated. Maximum head is the theoretical maximum pressure the pump can withstand when the valve is closed. The operating head is typically 50% to 80% of this value. Maximum flow rate is the flow rate when the pump valve is fully open and the head is at its lowest.
There are three types of motors: permanent magnet brushless DC motors (permanent magnet synchronous motors are one type) and AC single-phase or three-phase asynchronous motors. Permanent magnet brushless DC motors are a recent product and are currently the most advanced pump motors. They range from square-wave driven brushless DC motors to sinusoidal-wave driven permanent magnet synchronous motors. These motors require a controller, and the power supply can be either solar energy or AC rectifier. Single-phase or three-phase asynchronous motors are currently the most commonly used motors. Typically, single-phase AC 220V is used for power below 2.2kW, and AC 380V is used for power above 2.2kW. When using solar energy for this type of water pump, an inverter is required to convert solar energy into AC power for the pump to operate.
DIFFUL offers high-quality solar water pumps of various types and specifications. They are easy to install and maintain, have low operating costs, are suitable for unattended operation, and can also be used in combination with other energy sources.
