Solar Pumps
The output from a PV array is DC (direct current), the pump needs to be fitted with DC electric motor, or alternatively an inverter is used to convert the DC to AC. Recently, brushless, maintenance-free, DC motors appeared on the market, this type of motor is becoming increasingly popular for solar pumping applications.
Submersible Centrifugal- or Positive displacement pumps are used with solar pumping systems. They run more or less maintenance free for years.
