Claim Text:
1. A photovoltaic (PV) generating system comprising: a plurality of PV tracker units, each comprising: at least one of the PV panels being connected in series with another of the PV panels to form a serially connected PV panel pair; a multiple tracker control unit in communication with the plurality of PV tracker units, the tracker control unit monitoring the output electrical power of the PV panels and controlling, in dependence on the monitored output electrical power, both: (i) power conversion of the output electrical power and (ii) the actuators of the PV tracker units, to optimize power output for the plurality of PV tracker units, the multiple tracker control unit being configured to perform a calibration routine during which a calibrated trajectory for each PV panel is calculated in dependence on the output electrical power therefrom, and wherein power conversion of the output electrical power from each PV panel comprises performing a DC-DC conversion to output a substantially constant voltage electrical power output signal, wherein the calibration routine comprises, for each serially connected pair of PV panels:
