Solar irrigation in a 96ha citrus plantation

It is a grid- connected solar installation that feeds eight deep well submersible pumps and fills a 25,000m3 reservoir and a horizontal pump. Bombeatec executed the turnkey project, which includes the installation of the solar trackers, the solar panels, the AC PUMPING STATION, and the WEATHER STATION.
The system can work in hybrid mode, always prioritizing the energy obtained from the PV generator. Thanks to Bombeatec’s control algorithms, it is possible to adapt the consumption profile of the pumps to the solar generation profile, maximizing the savings obtained. A 50% saving has been made on the electricity bill, achieving a return on investment over 5 years.
The system is autonomous thanks to the AC PUMPING CONTROLLER, which performs intelligent management of the system. The following functionalities can be noted:

• Zero injection of energy into the network
• Reactive energy compensation
• Priority-based pump activation depending on the availability of solar energy
• Pump start/stop efficient management considering solar intermittency and cloud passages
• Auxiliary energy source management: isolated or hybrid mode depending on Time of Use tariffs and contracted powers
• Wireless communications with the different water collection points
• Integrated trackers control
• Weather station monitoring
• Mobile app for remote access
