PV Pumping Technology :
1. Solar PV array: The PV array consists of multiple solar panels connected in series/parallel, which can supply the whole system as power source by converting the absorbed solar radiation energy to the electrical energy.
Diesel Pumping Technology :

2. Solar
Pumping Inverter : Solar pumping inverter can implement the control of the whole system operation,
which drives the pump
by converting DC power produced by the PV array to AC Power. This inverter can adjust the output frequency according to the solar irradiation
intensity in real time to implement the MPPT
(Maximum power point tracking).
3. Water Pump : The pump driven by a 3-phase AC motor draws water from deep-well or river. The pumped water is then fed into reservoir or water tank, or connected to the irrigation system or fountain system directly. All of centrifugal pump, axial-flow pump, mixed- flow pump, and deep-well pump can be utilized.

Diesel Pumping Technology :
1. Diesel engine:
2. Pump element: The most common pump
type is the helical
rotor
pump
also referred
to
as the progressive cavity pump and the piston pump.
3. Discharge/Pump head: The discharge head is fitted above the centre of the borehole. The rising main is fitted
to the bottom of the discharge head and the engine is coupled to the pulley through belts. The discharge head transfers the power of the engine to the pump via a circular (progressive cavity)
or a
reciprocating (piston) action.
4. Rising main: The rising main consists
of 3m galvanized steel pipes (40 or 50 mm diameter) which
are
coupled together. The rising main pipes either come with a taper thread or parallel thread. The taper is cheaper to manufacture but does not exhibit the strength of the
parallel threaded pipe. Taper threaded pipes are recommended for hand pumps but not
diesel pumps. However in reality, taper threaded pipes are often installed due to the
initial cost savings. A shaft transfers the power down the centre of the column either through a circular action or through a reciprocating action. The shaft is guided either
through bobbin bearings or guides
