Empire Solar Water Pump
A surface pump is one that is mounted at ground level.
A submersible pump is one that is lowered into the water. Most deep wells use submersible pumps.
A pump controller (current booster) is an electronic device used
with most solar pumps. It acts like an automatic transmission, helping the pump
to start and not to stall in weak sunlight. Storage is important. Three to ten days' storage may be required, depending on climate and water usage. Most systems use water storage rather than batteries, for simplicity and economy. A float switch can turn the pump off when the water tank fills, to prevent overflow.
A Solar Panel (photovoltaic-PV) is needed to provide energy. A PV array may be placed some distance away from
the pump itself, even several hundred feet (100 m) away. Pressure: The amount of force applied by water that is either forced by pump or gravity. Measured in Pounds per square inch (PSI).
What a water pump is used for
Livestock Watering: Cattle ranchers have their water sources scattered over vast rangeland where power lines are few, and costs of transport and maintenance are high. Some ranchers use solar pumps to distribute water through several miles (over 5 km) of pipelines. Others use portable systems, moving them from one water source to another. For game parks and game farms, it is used for watering applications.
Conservation areas: Surface water pumping
Irrigation: Solar pumps are used on small farms, orchards, vineyards and gardens. It is most economical to pump PV array-direct (without battery), store water in a tank, and distribute it by gravity flow. Where pressurizing is required, storage batteries stabilize the voltage for consistent flow and distribution, and may eliminate the need for a storage tank.
Domestic Water: Solar pumps are used for private homes, villages, medical clinics, etc. A water pump can be powered by its own PV array, or by a main system that powers lights and appliances. An elevated storage tank may be used, or a second pump called a booster pump can provide water pressure. Or, the main battery system can provide storage instead of a tank. Rain catchments can supplement solar pumping when sunshine is scarce. To design a system, it helps to vi ew the whole picture and consider all the resources.
Other benefits of a solar water pump:
Stand alone, pollution free, low noise operation pump.
They are easy to install, require very little maintenance and are repairable. Free Energy!
