Solar-Powered Water Pump

Solar Water Pump:

Solar powered water pump with an electric motor run by electricity generated from solar radiation by Photovoltaic panels or the Radiated Thermal energy. Photovoltaic panels convert solar energy into direct-current (DC) electricity. Hence, a DC motor is required to operate solar PV water pump. The AC motors can also be used to run the solar PV water pump however, direct-current (DC) is converted to alternating-current (AC) using an inverter which is more complex and costlier. The solar-powered water pump is used to provide fresh water for different purposes such as domestic use, industry, agriculture, livestock, fish ponds etc. Use of solar powered water pump decreases the input cost up to 25% which can make agriculture cost-effective. A solar-powered water pump used for irrigation. Solar pumps are useful where grid electricity is unavailable or impractical, and alternative sources (in particular wind) do not provide sufficient energy.

The various uses of solar water pumps are as follows:

(a) Domestic water supply:

Solar-powered water pump can be a good solution for a reliable supply of clean water. Now-a-days, use of solar-powered water pump is increasing because of its several advantages. A Solar water pumping system used for domestic water supply. The solar water pumps are suitable for pump small quantity of water thus it is best suited for villages as well as domestic water supply. Groundwater is a good source of clean water which is used for different purposes especially for drinking in villages. The reliability of regular supply of clean water in remote and rural areas can be ensured by using the solar-powered water pump. When water is pumped by solar water pump, the cost of water is very less as compared to other water pumping methods i.e. diesel or electrical.

 

(b) Irrigation:

Water is the basic necessity for crop production. Irrigation is an important input for agriculture. Irrigation at right stage/time to the crops is important otherwise crop yield will be drastically decreased. Hence, continuous water supply is required for sustainable agriculture production. SPV water pumping system is a viable solution to provide regular water supply for irrigation especially in remote locations where a steady electricity supply or fuel supply is problematic. SPV water pumping system used for irrigation.

 

(c) Livestock: 

Livestock rearing is one of the important activities in rural areas. Regular water supply is required for drinking, bathing of livestock etc. Use of PV water pumps in livestock farm can be one of the alternatives for regular water supply which is gaining prominence especially in off-grid areas.

 

(d) Solar Water Pumps for Aquaculture and Fishing:

Power aeration pumps are used in commercial fish and shrimp farms it helps in increasing oxygen levels, which contributes significantly to productivity. Most of the farms located in the remote, off-shore locations use conventional energy sources like diesel generators and grid supply. These energy sources are costly and present an ecological hazard, especially close to vulnerable aquatic eco-systems. For small applications (aeration pumps) PV can be an economic solution. For higher energy consuming applications, solar PV/diesel hybrid systems can be an option.
