A system for generating electrical energy, for instance at an agricultural site, said system comprising:

• at least one mobile robot, referred to as “collecting robot”;
• a plurality of mobile robots, referred to as “producing robots”;
• wherein each collecting robot comprises:
• at least one input port adapted for coupling with an output port of a producing robot, for receiving electrical energy thereof;
• an output port for outputting electrical energy received from each producing robot coupled with the collecting robot;
• wherein each producing robot comprises:
• a photovoltaic, PV, generator for generating electrical energy;
• at least one input port adapted for coupling with an output port of another producing robot, for receiving electrical energy thereof;
• at least one output port for outputting electrical energy generated by the producing robot and received from each other producing robot coupled with the producing robot.
