Heart Of Irrigation System
A water pump is the key to making any irrigation system work efficiently. It helps move water from your source—like a river, pond, or tank—to where your crops or garden need it. Whether you're using sprinklers, drip lines, or flood irrigation, the pump ensures consistent flow and pressure so your plants get the right amount of water at the right time. Without a pump, it's hard to cover large areas or maintain steady water delivery, especially on uneven land or when the source is far away.
Step 1.
Know your water needs
The amount of water needed for irrigation not only depends on the crop type but also on the irrigation method used. For example, drip irrigation delivers water directly to the plant roots, which requires relatively lower need. Sprinkler systems distribute water over a wide area, simulating rainfall, and are well-suited for uniform coverage of vegetables, grains, and turf but may have higher evaporation losses. Choosing the right system can significantly impact water use efficiency, crop yield, and operational costs.
Step 2. Calculate the lift and head
The height of the water tank and under water are regarded as vertical distance. The distance between the pump and the water tank is considered as horizontal distance, with these information, we can roughly calculate the head of the pump.
Step 3. Pair with right solar panel
The solar panel array should be 1.3 times the water pump's power, with voltage matching the pump's range.

What is your application?
What is your application?
Identify how you’re applying water: drip, sprinkler, flood, or other. Each method has different flow and pressure needs.
How to calculate flow rate?
How to calculate flow rate?
Required GPM = Total Daily Water Need (gallons) ÷ Pump Operating Time (minutes)
For example:
Drip system for 2 acres = ~4,000 gallons/day
Pump runs for 2 hours (120 min)
4,000 ÷ 120 = 33 GPM required
In this case, a pump rated 35-40 GPM is recommended.
How to calculate head
How to calculate head
Lift head = Lift + Friction + Pressure
Vertical Lift: Height from water source to outlet
Friction Loss:resistance from pipes and fittings (add about 1–2 feet for every 30 feet of pipe).
Pressure Head: Required by drip or sprinklers
(10 PSI ≈ 23ft; 30 PSI ≈ 69m)
For example:
If your tank is 26 ft high, you have 100 ft of pipe (add 5–6 ft for friction), and your sprinklers need 66 ft of pressure, your total head is:
26 + 6 + 66 = 98 feet
In this case, pump rated > 98 ft is recommended.
