Abstract: The present disclosure provides junction boxes for use with roof-mounted photovoltaic (PV) modules. The junction boxes may include a housing having a plurality of sides, a bottom having an aperture, and a top edge having a top opening, where the top edge has a lip disposed around the top edge and projecting upward from the top edge. The junction boxes may further include a lid removably coupled to the top edge of the housing and a seal disposed on an outer surface of the bottom of the housing.

Abstract: The present disclosure provides photovoltaic (PV) module mounting systems and bracket assemblies for securing PV modules to roofs. The photovoltaic module mounting systems may include a roofing panel having a base layer, a flashing panel coupled along an edge of the roofing panel, and a bracket assembly coupled to the roofing panel, where the bracket assembly includes a bracket and a clip, and where the clip is configured to couple with an edge feature of a PV module to secure the PV module to the roofing panel.

Abstract: A solar-tracking photovoltaic (PV) system having several PV modules mounted on a torque tube is described. The torque tube may include several sections joined by a torque tube coupler. For example, the torque tube coupler may having a medial section and end sections to join to the torque tube sections. The medial section and the torque tube sections may have a same outer diameter.

Abstract: A pin may be arranged in a hole located on an outer diameter surface of a cylinder of a rotary die cutting arrangement. The pin proximal end may be received in the hole and the pin distal end may project from an outer surface of the cylinder. The pin proximal end has a boss. The pin has a longitudinal slit extending from the proximal end toward the distal end. The slit has a width and length dimensioned to provide the proximal end with sufficient resiliency to allow the proximal end to be compressed to a position where the boss of the pin proximal end has a diameter less than the diameter of the hole to allow the boss to pass through the hole, and release to a position where the diameter of the boss is greater than the hole diameter to retain the pin in the hole.
