A reliable, clean water supply is essential, but many people today do not have this basic supply. Solar water pump is a socially and ecologically attractive technology for water supply. Especially when water needs are in remote locations that are beyond the reach of power lines, solar power is often the technology of choice from an economic perspective. Silan is the best in all top Solar Pump Manufacturers in India.
Solar water pumps can move water to locations that are out of reach of power lines. Usually such places rely on human or animal power or diesel engines for their water supply. Solar water pumps can replace current pumping systems and generate socio-economic and climatic benefits. Water supplied by a solar water pump can be used to water crops, to water livestock, or to supply drinking water.
There are two main types of solar water pump technology: a) centrifugal pump, which uses a high speed rotation to pass water through the center of the pump. Most conventional AC pumps use radial impellers. However, when the power is low, the pump power drops dramatically. This makes centrifugal pumps less suitable for solar power applications, as they are expected to produce low output due to cloudy weather. and (b) a positive displacement pump, which typically uses a piston to move water. Many solar water pumps use a positive displacement pump that squirts water into the chamber and then pushes it out with a piston or screw. This type of pump typically pumps slower than other pump types, but works well in low power conditions and can achieve high buoyancy. Because PV is expensive and its utility intermittent, solar pumps need to be as efficient as possible. Pump efficiency is measured by the amount of water pumped per watt of electricity.
There are two types of pumps: submersible pumps and surface pumps. Depending on the water source which type of pump is more suitable. In the case of a well, the pump must be placed under water. The surface pump can be placed on the side of the pool or in a floating pump near the water. Surface pumps are cheaper than submersible pumps, but are not suitable for suction and can only draw water from about 6.5 meters above sea level. Surface pumps are ideal for pumping water over long distances.
