A solar-powered pump is a pump running on electricity generated by photovoltaic panels or the radiated thermal energy available from collected sunlight as opposed to grid electricity or diesel run water pumps.
Solar powered water pumps can deliver drinking water as well as water for livestock or irrigation purposes. Solar water pumps may be especially useful in small scale or community based irrigation, as large scale irrigation requires large volumes of water that in turn require a large solar PV array. As the water may only be required during some parts of the year, a large PV array would provide excess energy that is not necessarily required, thus making the system inefficient.
A solar powered pump is a pump running on the power of the sun. It makes efficient use of solar energy and converts it into electrical energy for pumping water to great heights. A solar powered pump can be very environmentally friendly and economical in its operation. This system operates on power generated using solar PV (photovoltaic) system. The photovoltaic array converts the solar energy into electricity, which is used for running the motor pump set. The pumping system draws water from the open well, bore well, pond etc. The water pumping system can be used to irrigate land, when the water is to be pumped from a depth of well or a pond.
A typical solar powered pumping system consists of a solar panel array that powers an electric motor, which in turn powers a bore or surface pump. The water is often pumped from the ground or stream into a storage tank that provides a gravity feed, so energy storage is not needed for these systems. Photovoltaic (PV) powered pumping systems are a cost-effective alternative to agricultural wind turbines for remote area water supply.
Photovoltaic (PV) systems are used to pump water for livestock, plants or humans. Since the need for water is greatest on hot sunny days the technology is an obvious choice for this application. Pumping water using PV technology is simple, reliable, and requires almost no maintenance. For farmers with a creek running through their properties, using a solar powered water pumping solution means less fouling of waterways and far less erosion of banks. It can also lead to better pasture management as livestock will be able to access water via multiple distribution points.
