A pony module having a solar panel may power a controller and/or drive device in a solar tracker. The pony module may be mounted directly on the drive device or a cradle supporting a solar panel support (e.g., a torque tube) attached to the drive device. The controller may be mounted on the solar panel of the pony module or may be mounted on the torque tube itself.

In an example, the present invention provides a solar tracker apparatus. In an example, the apparatus comprises a center of mass with an adjustable hanger assembly configured with a clam shell clamp assembly on the adjustable hanger assembly and a cylindrical torque tube comprising a plurality of torque tubes configured together in a continuous length from a first end to a second end such that the center of mass is aligned with a center of rotation of the cylindrical torque tubes to reduce a load of a drive motor operably coupled to the cylindrical torque tube. Further details of the present example, among others, can be found throughout the present specification and more particularly below.

A fluidic actuator including an angled bottom plate having a cap and first and second plate arms on opposing sides of and extending from the cap. The fluidic actuator further includes a top plate coupled about the cap of the angled bottom plate and a rotatable coupling of the angled bottom plate and top plate.

A solar tracker system having one or more solar trackers that each include one or more panels and one or more actuators coupled to the one or more panels, the one or more actuators having a first and second vessel; and an electronic control unit configured to inflate the first vessel with fluid from a fluid source and configured to separately inflate the second vessel with fluid from the fluid source. The electronic control unit is configured to determine that a stow event is present based on a first set of environmental data obtained from an environmental sensor that indicates environmental conditions pose a threat to the one or more solar trackers, and in response to determining that the stow event is present, actuate the one or more panels toward a stow configuration target angle by at least inflating the first or second vessels with fluid from the fluid source.

A fluidic actuation system for controlling rotation of one or more panels, having a first valve circuit configured to be fluidically coupled to a first vessel and a fluid source, having a first and second valve; and a second valve circuit configured to be fluidically coupled to a second vessel and the fluid source, having a third and fourth valve. The first valve is configured to control a supply of fluid from the fluid source to the first vessel; the second valve is configured to release fluid from the first vessel; the third valve is configured to control a supply of the fluid from the fluid source to the second vessel; and the fourth valve is configured to release the fluid from the second vessel. Introduction or release of fluid from one or both the first and second vessels is configured to cause rotation of the one or more panels.

The present invention concerns a solar tracker (1000) comprising at least: a mobile device (1100) comprising at least: a table (1110) comprising at least one solar energy collector device (1112); a support structure (1120); first support arch (1130) and a second support arch (1150) configured to support the support structure (1120); a first ground support (1140) and a second ground support (1160) configured to support the first support arch (1130) and the second support arch (1150), respectively; a kinematic drive device (1141);
the solar tracker (1000) being characterized in that: the support structure (1120) is a beam formed of a lattice structure comprising: at least one first, one second and one third longitudinal members; a plurality of crossmembers; a plurality of tie rods (1225).

The disclosure relates to a solar tracker assembly, particularly for solar collectors, with a table structure for supporting the solar collectors, particularly solar collector panels and/or solar collector assemblies, and with an assembly for carrying the table structure, wherein the table structure is rotatable relative to the assembly base at least about one axis of rotation. For allowing the table for supporting respective solar panels to have sufficiently large dimensions in order to accommodate an increased number of solar collectors in an easy way and, at the same time, to enable the table to be positioned at a precise angle with reduced effort, it is suggested that at least a portion of the table structure and/or a portion of the assembly base is formed as a truss structure.

A solar tracking system for tracking the orientation of solar energy is disclosed. The solar tracking system may be integrated with solar cells and solar concentrators. The solar tracking system may have a first (22) and second (24) tracker module array that are opposite from another, aligned in substantially identical orientation, and form a tracker module pair array (1000). Tracker module pairs (12, 14; 12, 144) may allow motion relative to one another while maintaining substantially identical orientation. Solar concentrators may be attached to opposing tracker modules of a tracker module pair forming an array of solar concentrators. A base bar array (28) may be coupled to at least one tracker module pair. A transmission may operably rotate the base bar array and the tracker module pair array simultaneously.

A solar tracker including a torque tube, a drive device connected to one end of the torque tube, a frame assembly coupled to the torque tube, the frame assembly arranged perpendicular to the axis of the torque tube and supporting a plurality of solar modules. The solar tracker further includes a clamp assembly having a housing coupled to the torque tube where the torque tube is coupled to the housing, the housing having an opening with a major plane normal to a length of the torque tube, the opening having an inner region that acts as a stop for the torque tube when moved in a first direction, and as a stop for the torque tube when moved in a second direction and the drive device is operable to move the torque tube about a center of rotation from a first position to a second position.

A system for controlling a rotation of one or more solar panels about an axis of rotation, comprising one or more solar panels defining a longitudinal axis, one or more bellows actuators coupled to the one or more solar panels and defining an axis of rotation parallel to the longitudinal axis of the panels, a fluid source, a first valve circuit coupled to the bellows actuators and the fluid source, a second valve circuit coupled to the bellows actuators and the fluid source, and a controller, wherein introduction or release of fluid from one or more of the bellows actuators is configured to cause rotation of the one or more actuators about the axis of rotation.
