Solar Water Pumping

A solar water pump system is essentially an electrical pump system in which the electricity is provided by one or several PhotoVoltaic (PV) panels. 

A typical solar powered pumping system consists of a solar panel array that powers an electric motor, which in turn powers a bore or surface pump. The water is often pumped from the ground or stream into a storage tank that provides a gravity feed, so energy storage is not needed for these systems. Mechanical pumps have a lot of uses nowadays. They are common in pumping water from wells, aquarium filtering, pond filtering and aeration. When it comes to water pumps, the main use of this device is the exchange of fluids such as water. From agriculture to the energy industry, pumps are found in a wide range of applications. 

The main working principle of a water pump basically depends upon the positive displacement principle and kinetic energy which helps pushing the water. Solar Well Pump Running by Consuming Solar PV Electricity. A solar water pump system is commonly seen in residential and commercial uses, as well as for irrigation of agricultural land. Through solar panels, the pump can eliminate the cost of energy and provide a more feasible option that uses energy from the sun (and not fuel-burning mechanisms) for pumping water.

 

Working of a solar water pumping system

The system operates on power generated using solar PV (photovoltaic) system. The photovoltaic array converts the solar energy into electricity, which is used for running the motor pump set. The pumping system draws water from the open well, bore well, stream, pond, canal etc. The system requires a shadow-free area for installation of the Solar panel.

How to buy an efficient solar water pump?

As we mentioned above, the investment costs associated with buying solar water pumps are coming down in the past few years. However, the factors which influence the efficiency of a solar water pump are numerous and include:

· Economic viability

· Access to money

· Installation, operation and maintenance

· Standardization and quality control of products and service

· Water management

· Social justice

Considering these factors, we can say that solar water pumping can provide significant environmental and socio-economic benefits at the farm and national levels. At the farm level, the technology can present a reliable source of energy in remote areas—and especially areas that are not connected to the electricity grid or lacking a regular supply of liquid fuels. On a national level, solar water pumping can help stabilize, increase and diversify agricultural production, which is the foundation of most African countries’ economies.

By definition, an efficient solar-powered water pumping system is one that receives plenty of sunlight and is installed specifically to the needs of the farm. In a world where there is a current energy crisis, there is a strong drive towards renewable energy. Despite the costs which are relatively higher, the real efficiency of solar systems is seen in their use over the years. As a renewable energy option, the exploitation of solar energy is a valuable option. The focus of deploying solar water pumping is obviously set to South Africa and regions with poor economic development but plenty of sunlight. Paired with the right environmental conditions, the right amount of PV panels and controllers and the right installation setup of energy storages, converters, inverters, pumps and motors—the solar water pumping system can present a farm and a nation with numerous benefits.

Shree Sun Energies Recommendations:-

If you are thinking or considering the applications of solar energy for agriculture, the benefits are numerous. With the ability to pump water for irrigation during dry and sunny weather in regions that need it most, panels like these can be easily installed and enable the pumps to work in wells of very low yields, offering a longer lifespan and plenty of energy in the long run.
