We all know that for farmers to have a good harvest, they must ensure that their crops have an adequate supply of water, so irrigation has become one of the most important and water-consuming activities in agriculture. And according to the Food and Agriculture Organization (FAO), irrigation accounts for about 70% of global freshwater withdrawals. So if you're a farmer, and you relies on irrigation to grow your crops, you know how important it is to have a reliable and efficient water pump. However, many farmers have been facing challenges in accessing and paying for irrigation water, especially in remote rural areas where grid power is unreliable or unavailable.
However, the popularity of solar water pumps has brought practical solutions to these challenges. Since solar water pumps operate on solar energy, they do not require connection to the grid or diesel generators. Therefore, as long as there is a water source, whether it is a well, river, lake or pond, solar water pumps can be installed on-site, whether in remote mountainous areas or places with unstable or frequent power outages.
Solar water pumps also offer many advantages over traditional pumps. The following are some of the benefits of using solar water pumps for irrigation:
Besides the initial investment cost, which is mainly solar panels, controller, pump and other small accessories, the solar water pump has almost no cost in the later operation because it is solar powered and requires no electricity or fuel. However, the initial investment cost can be evened out by the fuel or electricity savings over a few years, so it is very economical in the long run.
Solar water pump is safe in operation, no noise, no other public hazards. It does not produce any harmful substances and is absolutely environmentally friendly.
Solar water pumps run off-grid, no need to dig trenches and bury wires, and can run independently as long as there is enough sunlight. Especially suitable for places where there is plenty of sunlight and no electricity, lack of electricity, or where the grid is out of reach.
the design life for solar panel of the solar water pump is 25 years and the pump is IP68 waterproof, so it requires little maintenance, you just need to keep the solar surface clean and free of leaves and dust
Solar water pumps are very easy to install and operate. You just need to connect the solar panel to the pump controller, r then connect the pump controller to the pump and you're done!
Solar pumps can improve your crop yield and quality by providing a steady and adequate supply of water to your plants. By using drip irrigation, you can lock water into the roots of your plants, reduce weed and disease pressure, and increase water and fertilizer efficiency. You can also irrigate hilly areas that are difficult to reach with traditional pumps.
Nowadays there are different types of solar water pumps in the market. These following factors are determining which type of solar water pump for your irrigation:
- Water source: whether it is surface water, such as a river, pond (surface) or underground, such as a deep water well (submersible).
- Head: The vertical distance between the water source and the discharge point.
- Flow rate: The amount of water delivered per hour.
- Power source: whether it is direct current (DC) or alternating current (AC).
The main differences between these four types of pumps are
These put the pump directly into the well and use direct DC power from the solar panel to power the pump directly. They are suitable for deep wells with high head and low flow requirements.
These are pumps that are placed above the water source and use direct current from the solar panels to power the pump. They are suitable for shallow wells or surface water sources with low head and high flow rate requirements. They are cheaper and require smaller solar panels than submersible pumps.
These are submerged pumps that use AC power from an inverter to convert DC power from solar panels. They are suitable for deep wells with high head and high flow rate requirements. They offer the same benefits as submersible DC pumps, but they also offer greater flexibility in power supply options. They can use grid power or batteries as a backup power source when solar power is insufficient.

Before choosing a pump, you need to consider three factors:
the amount of water you need for each irrigation: you need to know exactly whether you need to irrigate every day or every few days, approximately how many cubic meters of water you need each time, and whether you need to install a water tower
Your water source type: whether you need to pump water from a river, pond, or well, and what is the vertical distance of the water surface from the well or outlet, which determines whether to choose a submersible or surface pump
What is your budget: we know that of course the higher the power, the higher the water flow, but also the higher the cost. But if the budget is exceeded, everything is empty talk, so choose the right, not choose the largest
If you have interested in buying solar pumps for irrigation for your farm, We can recommend some types for your reference.
DC solar submersible pump, using solar energy to pump and transport water, it is currently the most attractive way to supply water in sunny areas of the world, especially in remote areas where electricity is lacking. Mainly used for household water supply, agricultural irrigation, garden watering, etc.
This series of solar powered overland pumps, applied to river pumping, have high flow rates and are suitable for agricultural irrigation. Water can be transported to higher and larger areas
These are the configurations that our customers often purchase.
