Which solar pump is better AC or DC?

Which solar pump is better AC or DC?

  • 2021/06/15
The solar water pump is the heart of solar pumping system, so selecting the good reliable pump is a crucial choice in building your efficient system.
Mainly in the market there are 2 types of solar pumps: AC pump and DC pump.
DC solar pump uses DC motor which works based on direct current supply (such as solar panel or battery), so it does not need an inverter.
While AC solar pumps uses AC motor which powered via solar pump inverter that converting DC getting from solar panels to AC.
Solar photovoltaic technology works on DC power.  So basically the power coming out of a solar PV panel is pure DC (Direct current) power.  The DC power coming from a solar panel is unregulated power, and hence it can not be used directly for any useful application.  We do need some kind of electronic circuit to control this unregulated dc power source into usable energy whether it is DC power or AC power.

Many times people wonder whether they should prefer to use the DC power directly or choose the option of converting the DC power into AC power.

  • DC pump is more efficient than AC pump and required less solar panels to operate
  • DC solar pump has longer life time as it uses motor coils manufactured from pure copper
  • DC pump is less noisy, it is totally quite because it uses internal BLDC motor with high manufacturing technology while AC pump uses old motor technology, moreover the noisy sound of AC pump will increase with time usage increase.

Catflo has more years experiences design on dc solar pump, diaphragm water pump, electric sprayer. We are professional solar deep well submersible pump manufacturer in China.
