As the cleanest, pollution-free and renewable green energy, solar energy is beneficial to the sustainable development of countries and regions, and is of great significances. Compared with the increasingly expensive oil, solar energy is more economic. If a set of tens of kilowatts of solar water pumping system is applied to replace the same power diesel pump, it takes only a few years to retrieve its initial investment, and will enjoy a free running hereafter.

Manna Solar’s ® solar photovoltaic water pumping system has obtained many patent technologies by adopting a number of latest technologies in related fields. In the late ***0s, it was successfully applied by the national Ministry of Science and Technology in the assistant project in Zimbabwe. In recent years, Manna Solar has achieved plentiful experience by setting up many demonstrations in different countries and regions after continuous deep research and development. Meanwhile, we have completed the first photovoltaic water pumping system in China- Golden Sun Project, which has been successfully checked in ***1. Several years’ experience has proved that photovoltaic water pumping system features high efficiency, reliability and economic benefits.

â– 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.

â– 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.
 

The main parts including water pump, solar energy module, control inverter, and photovoltaic arrays.

â–  The system is formed with different power levels. The largest flow of deep well submersible pump can reach **0m³/h，and the raising capacity can reach as high as **0 meters. The system can also be applied in other pumps besides deep well submersible pump.
