摘要： A solar tracker assembly is provided which includes a support column, a torque tube or torsion beam connected to the support column, a mounting mechanism attached to the torque tube or torsion beam, a drive system connected to the torque tube or torsion beam, and a spring counter-balance assembly connected to the torque tube or torsion beam. An exemplary spring counter-balance assembly comprises a bearing housing and a bushing disposed within the bearing housing and configured to be slideably mounted onto the torque tube or torsion beam, and one or more compressible cords made of a flexible material. The compressible cords are located between the bushing and the bearing housing and provide damping during rotational movement of the solar tracker assembly. An exemplary spring counter-balance assembly is provided including at least one top bracket and at least one bottom bracket, at least one spring, a damper, and a bracket. An exemplary spring counter-balance assembly comprises a bearing housing and a bushing disposed within the bearing housing and configured to be slideably mounted onto the torque tube or torsion beam. The spring counter-balance assembly may include at least one coil spring and a rotational stop. The bushing may be made of an elastomeric material and define one or more air spaces.

摘要： A method may include orienting a set of solar power units in a first position in which rows of solar power units are shaded by adjacent rows of solar power units; and monitoring energy generated by the set of solar power units over a window of time, that includes from when the set of solar power units are oriented in the first position until a sun angle corresponds to none of the rows being shaded by the adjacent rows. The method may include identifying a knee in energy generation during the first window of time, where the knee indicates a transition from higher to lower rates of change of energy generation at a given solar angle. The method may include plotting a trajectory of future orientation positions over time of the set of solar power units that include an orientation and time corresponding to the given solar angle.

摘要： A method may include obtaining information from a weather forecasting service that relates to indicators of an incoming hail event. The method may include determining a stowing score that quantifies whether the hail event is likely to occur within a period of time based on the information from the weather forecasting service. Responsive to the stowing score exceeding a threshold value, a time at which the incoming hail event is likely to occur may be predicted based on the weather forecasting service information. The threshold value may indicate a threshold likelihood of the hail event occurring or a threshold period of time before occurrence. The method may include determining a wind direction at the predicted time at which the hail event is likely to occur and stowing photovoltaic modules based on the wind direction.

摘要： A deflection pad may include a body including two peaks, and a recess in the body between the two peaks, the recess may be sized to accommodate a fastener such that when deployed, the fastener is below a height of the two peaks within the recess. The deflection pad may include arms projecting in a direction generally opposite the two peaks, the arms biased inward towards the recess. The deflection pad may be included in a system that includes a torsion beam and one or more support racks to which multiple PV modules may be attached, where the support are racks attached to the torsion beam. One or more deflection pads may be positioned on the support racks to be below the PV modules.

摘要： A module mounting system may include a photovoltaic (PV) module frame including a mounting rail. The module mounting system may include a spring clip with a PV module frame interfacing element and a clip interfacing element. The spring clip may apply spring force via deformation to lock the PV module frame and a clip together. A second embodiment of the spring clip may include an upper component having one or more arms and a lower component having a central loop configured to rotate relative to each other and interface with the PV module frame or the mounting rail. A second embodiment of the module mounting system may include screwless clips including outer walls and inner walls coupled together as a continuous sheet of material. The screwless clips may couple to a respective mounting flange and a respective frame flange to lock the mounting purlin and the PV module frame together.

摘要： A mounting system may include a frame associated with a power-generating device, the frame including an opening. The mounting system may include a bracket mounting assembly. The bracket mounting assembly may include a top member having a first surface, a clamp, and a single bolt passing through both the top member and the clamp such that the clamp moves along an interface between the first and a second surfaces as the single bolt is tightened. The clamp may include the second surface corresponding to the first surface, an arm projecting away from the top member, and a flange at least proximate a top of the arm. The flange may include an ear at the top of the arm and a tab on a bottom side of the ear projecting back towards the top member, the tab positioned to interface with the opening on the frame.

摘要： A solar tracker assembly comprises a support column, a torsion beam connected to the support column, a mounting mechanism attached to the torsion beam, a drive system connected to the torsion beam, and a torsion limiter connected to an output of the drive system. When an external force causes a level of torsion on the drive system to exceed a pre-set limit the torsion limiter facilitates rotational movement of the solar tracker assembly in the direction of the torsion, thereby allowing the external force to rotate about a pivot axis extending through the torsion beam. Exemplary embodiments also include methods of aligning a plurality of rows of solar trackers.

摘要： A first embodiment of a torque tube coupler may include an outer body that includes a first abutting surface and a second abutting surface adjacent to the first abutting surface. Set screws may be inserted into one or more channels of the first abutting surface. Tightening the set screws may force the abutting surfaces away from each other and the outer body to press against an inner surface of a torque tube. Another embodiment of the torque tube coupler may include a central ring sized based on a size of a torque tube. The torque tube coupler may also include a set of fingers that extend away from a first side of the central ring and are shaped to flex radially outward. The torque tube coupler may include a core disposed within the set of fingers that, when drawn towards the central ring, causes the fingers to flex radially outwards.
