Systems and techniques for boltlessly supporting and securing solar modules are disclosed. For example, in an aspect, a system features a support structure including a support rail, and a frame including a plurality of rails each having a slot to receive a solar module therein and a bottom plate to boltlessly couple to the top surface of the support rail via one or more boltless mounting components. A boltless mounting component may include a post operative to interlock with an insertion hole for securing the frame to the support structure. Moreover, a locking pin may be disposed through a pin hole on each of the top surface of the support rail and the bottom plate of the frame, where the locking pin advantageously maintains a predetermined alignment and advantageously provides a shared electrical ground connection between the support rail and the frame.

Motorized system for holding and driving at least one solar energy collector, said system including: a supporting structure for the panel, movable at least in part in relation to the ground, so as to allow controlled displacement of the collector, notably about at least two axes of rotation, at least one blocking member, fixed in relation to the ground, at least one coupling member, movable with the collector and adapted to cooperate with the blocking element in at least one locking position of the collector, in order to hold the collector in the event of extreme winds, the coupling member being able to be moved into the locking position or locking positions as a result of a predefined movement of the collector, from a usual operating position where the coupling member is remote from the blocking member.

A lock assembly includes a driving member, a locking member, and a latch. The driving member includes a connection end, and a driving end movable with respect to the connection end. The connection end is arranged on a fastener. The locking member is rotatably arranged on a carrier through a first rotation shaft. The driving end is rotatably connected to the locking member through a second rotation shaft. The locking member includes a hook. The latch is arranged on the fastener. The hook is capable of hooking the latch. The driving end is configured to capable of driving the hook to disengage from the latch, and driving the carrier to rotate with respect to the fastener, or the driving end is configured to drive the hook to hook the latch so that the carrier is secured to the fastener.

A system for attaching a solar panel to a support, includes a support connector and a solar panel connector, where the support connector includes a U-shaped profile having a lower wall and two side walls, where an upper end of the side walls is bent inwards to provide vertical rails for receiving the panel connector; and the panel connector include a profile having: an upper C-shaped portion configured for receiving a side edge of a solar panel; a lower, upwardly oriented channel portion configured for receiving the vertical rail of the support connector; and at least one box-shaped portion connecting the upper C-shaped portion and the lower channel portion.

The present invention provides a boltless module mounting system and a method of installing a boltless module. The system includes at least one module frame containing a module laminate, at least one support structure having support rails, and multiple boltless mounting components. The mounting components attach the module frame to the support rails. The present invention also provides a boltless module mounting system including at least one module having posts and at least one support structure with support rails. The support rails have receiving slots with a receiving hole and two or more slide slots. The posts interlock with the receiving slots. The method includes aligning multiple boltless connectors, lowering a boltless module frame onto a support structure, and sliding the frame to interlock the boltless connectors.

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.

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.
