Abstract
Tracking systems for adjusting a photovoltaic array are disclosed. In some embodiments, the tracking system includes an actuator that moves one or more links to cause the array to rotate. The tracking system may be disposed below a torque rail of the tracking system. The actuator may be a slew drive that retracts or extends the one or more links to cause the array to rotate.
Claims10
A ground-mounted photovoltaic array assembly comprising:
- a photovoltaic array;
- a base;
- a tracking system comprising:
- a torque rail that defines a rotational axis about which the photovoltaic array rotates;
- a support column that supports the photovoltaic array, the support column being connected to the base;
- an actuator for adjusting the photovoltaic array, the actuator being disposed below the torque rail;
- a first mounting member and a second mounting member each connected to the torque rail;
- a first link connected to the actuator and connected to the first mounting member at a first attachment point, the first attachment point being spaced from the torque rail;
- and
- a second link connected to the actuator and connected to the second mounting member at a second attachment point, the second attachment point being spaced from the torque rail, wherein the first link and second link are connected in a single unit;
- and
- a controller to adjust the tracking system such that the photovoltaic array follows a path of the sun.
