Submersible solar pumps
Typically, diesel-powered pumps are used in areas where connecting to the electricity grid is difficult. Solar photovoltaic (PV) systems can be an attractive complementary energy source deployed alongside diesel pumps in areas with plenty of sunshine and where the cost to run power lines is high.
Photovoltaic systems have the benefit of being scalable, with capacity ranging from a few watts for applications such as automated farm gates or timers, to hundreds of kilowatts for the homestead and farm sheds. Rather than having one large centralised system, a number of distributed PV systems can be deployed at pump sites.
The family of solar submersible pumping systems ranges from 150W to 25kW, more than meeting the requirements of many irrigation, livestock and fish farming, and water supply applications.

The complete SQFlex pump range consists of 9 different pump sizes: 5 helical rotor pumps for medium to high heads and low to medium flows, and 4 centrifugal pumps for shallow heads and high flows. The pump is fitted with a highefficiency motor for DC and AC voltage. This makes pump sizing and selection extremely easy.
LORENTZ PS pumps are high quality products designed for drinking water supply, livestock watering and smaller irrigation applications. PS helical rotor pump systems deliver water economically, cleanly and reliably, anywhere.
Aquatec submersible pumps are designed to supply water in off-grid locations for homes, irrigation, livestock, ponds, and many other applications. This Made in USA 4" positive-displacement submersible deep well diaphragm pump is constructed with high-grade materials that are all potable water safe. The SWP pumps are designed to operate from any 12-30 Vdc power source, including 60 or 72 cell modules or 12Vdc or 24Vdc battery banks.
Solar‐powered submersible pump suitable for wells with a 4 inch diameter or larger. and designed to be strong and yet lightweight, the submersible pumps 9325 have a aide‐range of parts and kits for ease of rebuilding and repair.
Solar powered pumping Sytems
A typical solar-powered pumping system consists of solar panels connected to an electric motor that runs a bore or surface electric pump. A solar pumping solution will typically supply a DC pump that is connected directly to the solar panel and does not require a DC/AC inverter. DC brushless motors offer very high efficiency levels. For the applications requiring water to be pumped at night, tank stocked water can be fed by gravity when there is insufficient sunlight to power the solar pumps.
Designed for continuous as well as intermittent operation, solar submersible pumping systems are especially suitable for water supply applications such as villages, schools, hospitals, and single-family houses or farms and ranches, including watering of livestock and irrigation of crops and greenhouses.
