It is an installation isolated from the electrical network and that feeds a deep well submersible pump. Bombeatec executed the turnkey project, which includes the installation of a new pump and the pipeline, the hydrocyclone, the solar trackers, the solar panels, and the DC PUMPING STATION.
The installation has a generator that allows it to work in hybrid mode to be able to meet the water needs in the months of high demand when the solar hours are not enough. In this case, the generator starts at nightfall to finish the pending irrigation hours.
As it is a direct irrigation from a well, it is an essential requirement that the PV generator be built on a solar tracker with a North-South orientation to obtain the desired pumping results and work efficiently in the different hydraulic regimes.
The system is totally autonomous thanks to the DC PUMPING CONTROLLER, which performs an intelligent management of the system. The following functionalities should be highlighted:

  • Pump start/stop efficient management considering solar intermittency and cloud passages
  • Irrigation and fertigation programming
  • Wireless communications for managing solenoid valves and irrigation sectors
  • Integrated control of trackers
  • Mobile app for remote access
  • Auxiliary energy source management: night start of the diesel group if the scheduled irrigation hours for that day have not been completed (priority irrigation option)
