How a Solar Pumping System Works
A DC solar pumping system captures sunlight using solar panels, converting it into direct current (DC) electricity. This DC power then drives a pump, equipped with a brushless motor for efficiency.
A controller monitors and optimizes the pump's performance based on the available solar energy, ensuring consistent water flow even under varying sunlight conditions.

How a Solar Pumping System Works
How to calculate lift(deep well pump)?
H1(Lift from lowest water level to ground):mt
H2(Tank height and additional lift if available):mt
L(Horizontal distance of water delivery):mt
Rated head >H1+H2+10%
How to calculate Total Head(surface water):
L the horizontal distance from the water source to the
water tank.
H2 vertical height from water source to water tank
H=h3/10+h4
How to dimension the Solar Panels
The power of the solar photovoltaic panel array is recommended to be 1.3 times or more than the power of the water pump.The voltage of the solar photovoltaic panel array needs to meet the voltage range of the water pump
​
Step1 : Pump Power×1.3÷solar Panels' power =nr Of Solar Panels.
​
Step 2 : Number of solar panels *Open circuit voltage <Controller
maximum voltage(series mode is selected)
​
Step 3 : Number of solar panels *Operating voltage Within MPPT voltage range of the controller
