The system is composed of photovoltaic arrays, control inverter, submersible pumps, and water tank or pipe network.

The system contains no battery energy storage for the sake of the low maintenance cost.

A high-efficient AC submersible pump is adopted to meet the different requirement of lift and flow. Compared with DC pump, it features a larger power, a wider range of pumps selection, and easy maintenance.

The system boosts Maximum Power Point Tracking of solar energy (MPPT), which can automatically regulate its operating power according to the sunshine to acquire the best power.

The system has realized the transmission of remote monitoring data of global GPRS, so that a real-time supervision of the operation of the system has also been achieved. Meanwhile, the service and management have been both improved.

The system features a real-time monitor of the record of voltage, power and electric quantity of photovoltaic arrays, the frequency, speed and flow of water pump, and also the detection and protection of the operating temperature of the equipment.

An unattended system has achieved by adopting automatic control, including the daily startup and shutdown, automatic closing of water tank if it is filled up or of well in case of lacking of water, etc.

The system also possesses the switch between photovoltaic and net electric or diesel generator, and also provides some daily power supply to solve people's difficulties of life due to lack of power.
