Australia(2020)

Although all towns and inhabited villages in Australia have achieved full coverage of power grid, there is no reliable and stable power supply for many pastures in remote inland areas. Herdsmen have to use windmill pumps or diesel pumps to extract groundwater to provide drinking water for cattle, sheep and other livestock. According to the herdsmen's feedback, windmill water pump not only has high equipment cost, but also is difficult to maintain. Although the equipment cost of diesel engine water pump is low, the fuel cost and maintenance cost are relatively high. Fortunately, Australia has extremely rich solar energy resources. According to statistics, Australia's sunshine resources rank first in the world, with more than 80% of the ground solar radiation exceeding 5kwh / m2, and even as high as 6kwh / m2 in inland areas. Therefore, in recent years, Australian governments at all levels have actively promoted and advocated the application of solar energy resources in energy projects, especially the use of solar power to supplement the power supply of farms and pastures in inland off grid areas.

In October 2020, Shenzhen Solartech 600W permanent magnet solar pumping system was successfully installed in Australia. The project is used for agricultural irrigation in the off grid arid areas. The system is integrated with solar charging and discharging control module and equipped with battery. This system solution makes full use of the local abundant solar energy resources, which can not only ensure the stable operation of the pumping system in the daytime, but also store the surplus electricity generated by the solar system to the battery tank. When there is no sunshine at night, the water pump is driven by the battery power supply, which realizes the demand of 24-hour water supply for the project owner's drip irrigation system.
