Efficiency is very important for a solar water pumping system. Efficiency ultimately defines how much water the system will pump with the available power. With solar power (PV modules) then you are making a capital investment in your power source. With an efficient system you either spend less for the same amount of water or get more water from the same power source.
Efficient systems will start pumping earlier in the day, pump more water throughout the day and will stop pumping later in the day. Look at the charts below comparing a LORENTZ system against another high quality, global, solar pump system. Notice the difference depending on the weather.
Efficiency is in our company DNA, you even see the ETA η efficiency symbol in our logo.
As the energy from the sun is not constant, either seasonally or daily due to changing weather, a solar pumping system must adapt to the changing conditions and deliver the maximum water possible with the amount of power available. Software in the pump controller looks at the available power and changes how the pump is powered to maximise the water output.
Choosing the right materials and designs for products allows for precise tolerances, this assists with mechanical efficiency.
The LORENTZ ECDRIVE uses DC brushless motor technology, this technology provide almost twice the real world efficiency of equivalent sized AC motors.
