    Tips: Water well pump applications

    • Livestock irrigation: The water well pump plays a major role in the water supply on pastures in America, Australia and Southern Africa. The water sources in these areas are scattered over vast pastures with few power lines, and the cost of transportation and maintenance is very high. Some ranchers use solar water pumps to distribute pipes of several kilometers (more than 5 kilometers), others use portable systems to move them from one source to another.
    • Agricultural irrigation: The water well pump is used for small farms, orchards, vineyards and gardens. Direct water pumping (without a battery) is the most economic. It stores water in a tank and distributes it by gravity flow. In the case where pressurization is required, the battery stabilizes the voltage to maintain consistent flow and distribution, eliminating the need for a storage tank.
    • Household water supply: The water well pump can also be applied in private houses, villages, medical clinics and so on. The pump can be powered by a solar panel array or by the main power system that powers the fixtures and home appliances.
