What Are Solar Pumps & How They Work?

Feb 17,2023

What occurs if you reside in a developing nation and demand water to irrigate your crops but lack access to the electricity needed to get there? A switch that is interconnected with a power grid cannot simply be flipped. Now is the time when utilizing solar power can literally change your life.


There are other uses for readily available, clean water than drinking. According to the World Bank, the majority of the world's fresh water is utilized for agriculture. For places in developing countries, that proportion rises to 80–90% of total water consumption.


Likewise, the Food and Agriculture Organization estimates that agriculture is essential for the survival of approximately 60% of the world's population (FAO). What does this all mean if there is no reliable irrigation system and it doesn't rain? It implies that people suffer and harvests fail.


Fortunately, there is a solution that raises community wellness, decreases poverty, and enhances food security: solar-powered water pumps.


We'll go over what solar pumps are, how they operate, and their advantages in this article. Let's start with their functioning.


How Do Solar Water Pumps Operate?

Basically, photons from the sun are converted into electricity to power the water pump in solar-powered water pumps. It makes direct current (DC), which powers the motor that pumps water away from its source, using solar panels to harvest photons (units of light) from the sun. If the pump motor requires AC rather than DC, an inverter is utilized.


Components of a solar-powered water pump system include:


Solar Panels

Solar panels, also known as solar photovoltaic (PV) systems, use photons from the sun to transform light energy into electricity in three simple steps.


Solar panels contain solar cells that use photons from the sun to create DC electricity.

DC electricity is transformed into AC (alternating current) electricity using an inverter.

The water pump is run by this electricity.


Water Pump Motor

Any water source that can be used for irrigation, domestic use, or other uses is taken by the water pump motor, including underground or other water sources.



Since water pumps require AC electricity, the inverter transforms the original DC electricity into usable AC.



Pipes will move water from the source to whichever destination it needs to go, such as a holding tank, a filtration system, etc.


Water Tank

A water tank to store water for usage when there is no sunlight is frequently part of the water pumping system.


Pump Controllers

The water pump can be controlled and turned on and off by the controllers. By shielding the water pump from electrical hiccups or motor damage if it continues to operate when a water source goes dry, they can lengthen the water pump's lifespan. Moreover, controllers optimize water delivery.


Let's look at the advantages of solar-powered pumps now that you understand how they operate.



Advantages of Solar Water Pumps

Many populations in underdeveloped nations are forced to rely on rainfall and inhospitable water sources without solar-powered water pumps. Only twice a year's worth of harvesting may be possible due to the unreliable water supply.


Solar-powered water pumps offer a number of advantages. As follows:


Affordable to operate

The price of PV (photovoltaic) panels has greatly decreased, which has reduced the initial setup cost from earlier. Because the energy is generated by the sun rather than by burning fuel, operating costs are lower than for other systems. The initial cost of installing the solar water pump is outweighed by the long-term fuel cost reductions.



Solar power is a renewable resource. Renewable energy is produced from natural resources. Others claim that the greenhouse gases released during the production of solar panels render solar energy non-renewable.


While that does occur, no more toxic gas emissions occur during the process of producing solar energy. Solar-powered water pumps are regarded as clean energy sources as a result.


Useful in far-off places

An external power source is not required because the sun supplies the energy, hence a solar-powered water pump can be used in distant locations and regions without access to a power grid.


Easily maintained

The low number of mechanical components in solar-powered water pumps reduces the likelihood that parts will need to be repaired. They don't need to be maintained and can survive for many years.


Simple to install

Solar-powered water pumps can be put together and installed without the help of engineers. They are simple to assemble and can be done so by locals.




Since they are fueled by solar energy instead of electricity, solar-powered water pumps offer a dependable water source.


Access to Water for All

The world's population is expected to increase by two billion people by the year 2050, from 7.8 billion to 9.9 billion. To ensure that everyone has access to food and water given this growth rate, we will need to increase the usage of renewable, non-destructive energy sources.


According to the World Bank, improving agriculture would help 80% of the world's poor because it can lower poverty and increase food security. Solar-powered water pumps offer a solution. Among their water projects, TPON SOLAR PUMP also provides reverse osmosis and ultrafiltration as additional life-saving water filtration options.
