Solar water pumps are a relatively new concept in mechanics. A solar water pump system is commonly seen in residential and commercial uses, as well as for irrigation of agricultural land. Through solar panels, the pump can eliminate the cost of energy and provide a more feasible option that uses energy from the sun (and not fuel-burning mechanisms) for pumping water.

solar pumps present a clean, simple and energy-efficient alternative to traditional electric and fuel-driven pump sets. They are part of an environmentally friendly approach in agriculture and can be used to exploit every region, whether its developed or poor.

Due to their immense potential for productive use and agricultural productivity, solar water pumps are now powering more and more agriculture projects. Knowing that 40% of the global population relies on agriculture as its main source of income, access to water remains an ongoing struggle for many people.  This is what solar aims to change and introduce a cost-effective future for around 500 million small-scale farmers all around the world.

The main components in a solar pumping system include a photovoltaic (PV) array, an electric motor and a pump. Solar water pumping systems, on the other hand, are classified as either direct current (DC) or alternating current (AC) systems based on their motor’s ability. Recently, the concept of brushless DC (BLDC) motors for solar pumping water applications was presented as well.When it comes to stand-alone solar pumping systems, the main types include rotating and positive displacement pumps. Centrifugal pumps are the common choice for rotation and are designed for fixed head applications. Their output increases in proportion to their speed of rotation.
