Solar water pumps are commonly used in residential, commercial, and agricultural land irrigation. With solar panels, water pumps can eliminate energy costs and provide a more viable option that uses energy from the sun (rather than a combustion mechanism) to pump water. Below we will explore the specific principles and working advantages of the following solar water pumps.
The truth is, solar power may be the easiest way for farmers to generate energy, especially for those who live on the grid and with poor surrounding infrastructure. Therefore, the use of solar water pumps in agriculture is becoming more and more common. The concept of solar irrigation represents a virtuous circle that, when the sun is shining, nourishes the irrigation system and crops that rely on water to grow in sunny weather. As a result, a large amount of energy is released when it is most needed.
Due to the huge potential of solar water pumps in production and agricultural production, more and more agricultural projects are now being powered. With 40% of the global population relying on agriculture as their main source of income, access to water remains an ongoing struggle for many.
The main components of a solar water pump system include a photovoltaic array, a motor, and a pump. On the other hand, solar water pumping systems are classified as direct current (DC) or alternating current (AC) systems according to the capabilities of their motors. Recently, the concept of BLDC motors for solar water pumping applications has also been proposed.
When it comes to standalone solar pumping systems, the main types include rotary and positive displacement pumps. Centrifugal pumps are a common choice for rotary pumps and are designed for fixed head applications. Their output is proportional to the rotational speed.
In addition, according to the location of the pump (below the waterline and above the waterline), pumps are also divided into submersible pumps and surface pumps.
In summary, the main aspects related to the efficiency of a solar water pump are based on three variables, including pressure, flow, and input power to the pump.
When it comes to solar pumps and irrigation systems, one important thing to note is that their cost has dropped significantly over the past few years. According to a new study by the International Renewable Energy Agency (IRENA), by 2025, the cost of solar photovoltaic power generation will be 59% lower than in 2015.
The economic viability of solar water pumping systems varies from region to region and depends primarily on on-site conditions, crops, and markets. If you are in an area with plenty of sun and lots of groundwater, a solar pumping system is definitely recommended. Although the initial installation cost is higher, the lower maintenance costs and higher service life can bring you huge benefits in the long term.
