- 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.
Solar powered water pumping systems are similar to any other pumping system, only the power source is solar energy. PV pumping systems have, as a minimum, a PV array, a motor, and a bore pump. Solar water pumping arrays are fixed mounted or sometimes placed on passive trackers (that use no motors) to increase pumping time and volume. AC and DC motors with centrifugal or displacement pumps are used.
