Key Performance Expectations Maximum Head (70m): This is the “shut-off” head, meaning it is the theoretical maximum height the pump can push water. At 70m, the water flow will be very slow (a trickle). Practical Flow: For optimal water volume, aim to install this at a depth of 40m to 55m. At these depths, you can expect a flow rate of approximately 0.8 to 1.2 cubic meters per hour ($m^3/hr$), depending on sunlight intensity. Power Source: 275W–300W is the standard matching solar panel wattage for this motor size. Voltage: Most of these systems operate on 24V DC.
