Product Appearance
A DC solar pumping system harnesses sunlight through solar panels, converting it into direct current (DC) electricity. This DC power drives a pump with a brushless motor for enhanced efficiency. A controller monitors and optimizes the pump’s performance based on available solar energy, ensuring a steady water flow even under fluctuating sunlight conditions.

How to select the right pump
How to calculate lift (deep well pump)?
H1(Lift from lowest water level to ground):mtH2 (Tank height and additional lift if available):mtL(Horizontal distance of water delivery):mt
Rated head >H1+H2+10%L
How to calculate Total Head (surface water)?
L the horizontal distance from the water source to thewater tankH2 vertical height from water source to water tank
H=h3/10+h4
How to dimension the Solar Panels
Solar Panel Sizing Guidelines:
Panel Power Recommendation:
The power of the solar photovoltaic (PV) panel array should be at least 1.3 times greater than the power rating of the water pump.
Voltage Compatibility:
The voltage of the solar panel array must fall within the acceptable voltage range of the water pump.
