Total Dynamic Head (TDH):
Static head plus friction losses.
Static head: Vertical height from the dynamic water level to the highest point of delivery.
Friction losses: Pressure losses in the pipeline as height of a water column with the equivalent pressure. Proportional to the length, diameter, surface of the pipe and the square of the flow rate.
Pump unit: Pump end and motor.
Motor cable length: Cable length from the pump unit to the controller.
PV cable length: Cable length from the controller to the PV generator
Pipe length: Complete pipe length from the pump unit to the point of delivery
Tilt angle: Angle between the PV generator pane and the horizontal pane.
