Solar power, or energy created by the sun, can be harnessed in a number of ways, including through solar panels that convert the sun's rays into electricity. In the case of a solar pump, solar energy is converted into electricity and fed to a pump that circulates water. These types of units can be used in swimming pools, fountains and larger agricultural projects.
Types of Difful Solar Pumps
There are two main types of solar pumps. Surface pumps sit above ground and move water through pipes. These are handy for moving large quantities of water at a slow pace. Surface pumps are commonly found on farms or large irrigation systems where water needs to be moved from a lake or other body to fields or landscaping. There are also submersible solar water pumps. These units are installed underground, but the solar panels are connected above ground. Submersible pumps are used to move water from inside wells to the surface. (See References 1, 2).
Difful Solar Pump Components
Solar pumps operate using three main components. Solar cells collect the sun's rays and convert them into usable electricity. These cells are usually covered in silicon or another semiconductor material that produces direct-current electricity. Wiring moves the electricity from the cells to the pump, and the pump does the work of moving the water. Some systems may also contain a battery, which is charged when the sun is shining for use when it's dark outside. (See Reference 2).
Difful Solar Pump Installations
Direction solar arrays (solar modules) face is critical to system efficiency. Often times compass is used to determine module direction, facing south in northern hemisphere and vice versa. Angle of inclination should be similar to local latitude or choose best angle according to water flow requirement based on seasonal changes. Pump must be installed at least 1m lower than dynamic water level, higher than well pipe water filter, at least 5m above bottom of well to prevent sand and mud.
