Mechanical pumps now have many uses. They are common in pumping water from wells, aquarium filtration, and pond filtration. For water pumps, the main purpose of this device is to exchange fluids such as water.
Pumps are used in a wide range of applications, from agriculture to the energy industry. The main working principle of the water pump basically depends on the principle of positive displacement and the kinetic energy that helps to push the water.
Solar water pumps are a relatively new concept in mechanics. Solar water pumping systems are commonly used for residential and commercial purposes, as well as for irrigation of agricultural land. With solar panels, the pump can eliminate energy costs and provide a more viable option to pump water using energy from the sun (rather than a fuel-burning mechanism).
Introducing solar irrigation to poor and remote areas
At a time when the world is turning to solar energy, the use of solar energy in water pumping systems can significantly help and accelerate agricultural development in African countries and many other poor and remote areas. The concept is called solar irrigation and is used in many areas today.
The truth is, solar energy may be the easiest way for farmers to the production of energy, especially for those who live off the grid and have poor infrastructure near their homes. Therefore, the application of solar water pumps in agriculture is becoming more and more common.
The concept of solar irrigation represents a virtuous cycle - when the sun is shining, it feeds the irrigation system and feeds crops that depend on water in sunny weather. Therefore, a lot of energy is being released when it is needed most.
Classification and types of solar water pumps
For stand-alone solar pump systems, the main types include rotary pumps and positive displacement pumps. Centrifugal pumps are a common choice for rotation and are designed for fixed head applications. Their output is proportional to the rotational speed.
In addition, pumps are also classified into submersible and surface pumps according to their location (underwater and above the waterline).
In summary, the main aspects related to solar water pump efficiency are based on three variables, including pressure, flow, and pump input power. The efficiency of the wires to the water is a common metric for determining the overall efficiency of a solar water pump (as the ratio between the water-energy flowing out of the pipes and the energy passing through the wires through the solar panels).
Why solar water pumps are the ideal way to boost agriculture in remote areas (and Africa)?
The solar water pump is an environmentally friendly concept. What's more, the concept gets rid of any grid or fossil fuels used to pump water from the ground.
Advantages of solar water pumps
The first advantage of solar water pumps is that they are reliable in regional and remote areas. A perfect example is Africa, one of the poorest remote regions in the world, with abundant water resources, but also the most dominant region under the sun for most of the year.
On the other hand, Africa is thought to have 9% of the world's freshwater resources, equivalent to about 4,000 km3 of water per year. So deploying solar water pumps in Africa is a perfect alternative to any other fuel source and one that can stimulate life everywhere on the continent.
Solar water pumps are easy to transport and relocate, can be organized according to the needs of the farm, and have extremely low operating costs. Both of these are major advantages, in the long run, combined with their cost-effectiveness, suggesting that solar pumping systems are the perfect solution for sunny and land-rich areas.
In a world of the current energy crisis, renewable energy is gaining momentum. Despite the relatively high cost, the true efficiency of a solar system can be seen in years of use. As a renewable energy option, developing solar energy is a valuable option.
The focus of deploying solar pumping is clearly South Africa and less economically developed but sunny regions. Combined with the right environmental conditions, the right number of photovoltaic panels and controllers, and the correct installation setup of energy storage, converters, inverters, pumps, and motors, solar water pumping systems can bring many benefits to farms and countries.
