Water for your family
Solar pumps are used in private houses, huts, villages, medical clinics, etc. Pumps can be powered either by their own photovoltaic arrays or by the main system that powers the system. An elevated tank, or a second pump called a booster pump, can be used to provide the necessary water pressure. Or the main battery system can provide storage instead of tanks. When sunlight is scarce, rainwater harvesting can supplement solar pumping. In order to design a system, it helps to view the whole picture and consider all resources.
Poultry water consumption
Ranchers in the Americas, Australia, and Southern Africa are enthusiastic users of solar pumps. Their water sources are scattered over a wide range of pastures, with few power lines and high transportation and maintenance costs. Some ranchers use solar pumps to distribute pipelines for several kilometers (more than five kilometers). Others use portable systems and move them from one source to another.
Plant water
Solar pumps are used in small farms, orchards, vineyards, and gardens. It is most economical to supply pumps directly from photovoltaic arrays (without batteries), store water in water tanks, and then distribute pumps through gravity flow. When pressure is required, the battery stabilizes the voltage to maintain uniform flow and distribution and eliminates the need for storage tanks. Batteries also introduce cost, complexity and additional maintenance.
