A mounting rail configured to connect to a photovoltaic (PV) module may include an upper portion, a first alignment member, and a second alignment member. The upper portion may include a surface configured to physically engage with a bottom surface of a module rail associated with the PV module. The first alignment member may extend from the surface of the upper portion at a first location. The first alignment member may also be configured to physically engage with a side surface of the module rail. The second alignment member may extend from the surface of the upper portion at a second location. The second alignment member may also be configured to physically engage with the side surface of the module rail.

A method may include positioning one or more PV module mounting devices along a length of a structural component. The method may include specifying one or more parameters related to fastening the PV module mounting devices to the structural component, the one or more parameters indicating a spacing between the PV module mounting devices. The method may include fastening, by an automated attachment equipment, the PV module mounting devices to the structural component based on the specified parameters and moving the PV module mounting devices fastened to the structural component to an assembly platform.

A module mounting assembly that couples a PV module to a support structure is provided. The module mounting assembly may include a mounting bracket, a mounting pin, and a clamp. The clamp may be configured to couple the mounting bracket to the support structure and the mounting pin may be configured to couple the mounting bracket to the PV module. The mounting pin may have a number of features and designs that facilitate positioning the mounting pin within the openings and retaining the mounting pin in an installed state.

An on-site photovoltaic (PV) module assembly system and process may involve customizing assembly of a row of PV modules at the location of a particular solar site. Mounting rails or other mounting structures configured to interface a PV module with a torque tube may be positioned along the torque tube on site to account for physical characteristics and properties of the particular solar site. PV modules may be attached to one or more of the mounting rails by an adhesive. Using the adhesive to attach the PV modules to the mounting rails may increase the flexibility of PV module installation along the torque tube. Use of the adhesive may also decrease the number of fastening components included with the mounting rail and the PV module, such as a structural rail or module rails.

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.

Embodiments of the present disclosure may include a system for mounting PV modules to a torque tube, the system including a mounting rail, a first strap, a second strap, and a fastener. In some embodiments, the mounting rail may be configured to be secured to the PV module. In some embodiments, the first and second straps may each include a proximal and distal end and a rectangular cross-sectional shape, where a shorter edge of the first and second straps may be configured to interface with the torque tube. In some embodiments, the proximal end of the first and second straps may be coupled to the mounting rail and the distal ends may include a connecting portion. In some embodiments, the system may additionally include a fastener that may couple the connecting portion of the first strap to the connecting portion of the second strap.

Embodiments of the present disclosure include a rotation locking assembly for addressing dynamic effects of photovoltaic (PV) modules in a solar installation. In some embodiments, the rotation locking assembly includes a rotational locking mechanism, where the rotational locking mechanism includes a shaft, a locking component rotationally connected to the shaft, and a static cog that may be configured to engage the locking component and stop rotation of the shaft. Additionally, the rotation locking assembly includes a means for transmitting rotation of a torque tube to rotation of the shaft, where the locking mechanism is configured to limit rotation of the torque tube in response to an angular velocity of the torque tube exceeding a threshold.

A photovoltaic (PV) module clamp may be configured to interface with a torque tube and a PV module rail fixedly coupled to a PV module. The PV module clamp may include a seating portion made of two or more lateral walls and a base surface. A clamp body of the PV module clamp may be coupled to the seating portion. The clamp body may include a shape corresponding to a cross-sectional shape of the torque tube. The PV module clamp may include a fastening feature for interlocking the PV module clamp with the PV module rail responsive to the PV module rail being seated in the seating portion of the PV module clamp.
