Description/ Specification of Solar Pump

Solar pumps work with the energy of electrical power generated by photovoltaic cells based on the photoelectricity law and through the use of sunrays incident on them. Several solar cells are combined in solar panels and multiple solar panels combine to form a solar array. The more sunlight the panels receive, the more electricity is produced. The energy thus generated is channeled into running water pumps, which draw the water from a reservoir like a pond/river or well upwards to where it is to be utilized. They can be used for irrigation, storage, washing, cleaning, or any other use. Since electricity is only generated when sunlight is present, any surplus electricity can be stored in a bank of batteries and utilized later whenever required. Alternatively, water may also be stored in an over-head tank and utilized subsequently. Solar energy generates electric current in the form of DC, or direct current. If the pump to be driven is also DC, then there is no conversion required. Otherwise, it must be converted into AC power by an inverter. A controller is used in the circuit, which falls between the pump and the solar panel. It performs several functions, i.e., starting and stopping the pump, protecting the pump if there is low water level, etc. Advantage of Solar Pumps: As they run on sun power, they do not emit any poisonous exhaust like diesel pumps. In contrast to grid power pumps, they don't need any connection to the local grid, which costs money and is inconvenient in the case of remote areas. In addition, they are more reliable, since grid power is often not available or does not give good voltage, frequency, etc. Since the solar panels have no moving parts, they require minimum maintenance, except for occasional washing. Another advantage of another kind is that solar panels generate maximum power on sunny days in summer when water demand is also maximum for agricultural as well as non-agricultural purposes. Even though the cost of installation of solar pumping systems is more, their operating cost is much less. Nature and size of solar pumps: The size of the solar pump will depend on factors like the quantity of water to be pumped, the height at which it has to be lifted, and the distance it has to be raised to the point of ultimate use or local storage. The solar array size will be determined by the available solar incidence and the amount of pumping power required. For low power, DC pumps are used. In that case, DC power can be directly harnessed. Installation of a battery bank also leaves room for electricity storage for use later during evening hours. However, for larger irrigation systems, larger capacity centrifugal pumps, usually driven by AC power, are used. Then the expense rises as an inverter is required also. Solar pumps are either of the submersible or the surface type. Submersible solar pumps bring water up above a height from an underground point like a borehole or a well. They can typically pump water up to a height of 50 meters. Surface pumps are employed for lifting water from sources like ponds, rivers, shallow wells, etc., where heavy lifting power is not needed. Solar water pumps are an economical, eco-friendly, and low-maintenance substitute for traditional pumps. They are applied to agricultural, household, and animal husbandry requirements, particularly in rural regions. Some Indian companies that offer these pumps are given below. #solarpumps DECLARATION: TEXT CONTENT IN THIS PAGE IS AI GENERATED
