    摘要： Solar array (1) comprising solar modules (3) distributed in rows (10), each solar module comprising solar collector (5) carried by a single-axis solar tracker (4), a reference solar power plant (2) comprising a central reference solar module and at least one secondary reference solar module, and a piloting unit (7) adapted for:



    piloting the angular orientation of the central reference module according to a central reference orientation setpoint corresponding to an initial orientation setpoint,
    piloting the orientation of each secondary reference module according to a secondary reference orientation setpoint corresponding to the initial orientation setpoint shifted by a predefined offset angle;
    receiving an energy production value from each reference module;
    piloting the orientation of the modules, except for the reference modules, by applying the reference orientation setpoint associated to the reference module having the highest production value.

    摘要： A parallel inverter system for solar tracker systems minimizes circulating currents, mitigates ripple, and increases efficiency. The parallel inverter system includes inverters coupled together in parallel, a common DC bus coupled between a DC load and inputs of the inverters, a common AC bus coupled between outputs of the inverters and an electrical power grid, and a common-mode filter coupled to the output of each of the inverters. The parallel inverter system also includes controllers coupled to the inverters, respectively, the controllers configured to generate interleaved pulse width modulation (PWM) signals, respectively. The PWM signals are synchronized with each other. The PWM signals may be synchronized with each other via the EtherCAT protocol.

    摘要： A solar tracking system is provided and includes a solar array, a support structure configured to support the solar array, a base configured to rotatably support the support structure, and an articulation system configured to articulate the support structure relative to the base. The articulation system includes a gearbox that is coupled to the support structure and an actuator that is configured to extend and retract. The actuator includes a first end portion and a second, opposite end portion, wherein the first end portion is rotatably coupled to the base and the second end portion is coupled to the gearbox. Extension of the actuator causes the support structure to rotate about the base in a first direction and retraction of the actuator causes the support structure to rotate about the based in a second, opposite direction.
