How to configure solar panels-----Solar DC Pump System?

The power of the solar photovoltaic array is recommended to be 1.3 times or more of the water pump power. The voltage of the solar photovoltaic array needs to meet the voltage range of the water pump.

Example:

3-inch plastic impeller solar submersible pump
Model: 3DPC3.5-95-72-750
Model No.
GS-3DPC3.5-95-72-750
Pump Power
750W
Voltage
72V
Optimum Input Voltage
90V~120V
Max. Flow
3.5m³/h
Max. Head
95m
Water Outlet
1.25''
Cable
2m
Solar panel
Open Circuit Voltage(VOC)
＜105V
Power(W)
≥1.3*Pump Power
Pump power: 750w Optimal input voltage: 90-120v Maximum open circuit voltage: 160v
Solar photovoltaic panel array requirements: Power ≥ 750w*1.3 (i.e. power ≥ 975w)
VMP voltage > 90v VOC voltage < 160v
Single Solar panel:
Power: 330 watts VMP voltage: 37.26v VOC voltage: 45.64v
3 solar panels in series:
Power: 330w x 3 = 990w VMP Voltage: 37.26v x 3 = 111.78v Voc voltage: 45.64v x 3 = 136.92v
0
In this case, the power and voltage requirements of the water pump can be met, so this solar photovoltaic panel array solution is acceptable.
