The present invention is directed to an apparatus for stacking a plurality of solar module arrays each having a plurality of solar panels. The apparatus includes a lower portion disposed on top of a first solar panel support channel corresponding to a first solar module array, and an upper portion for supporting a second solar panel support channel corresponding to a second solar module array, wherein the second solar module array is stacked above the first solar module array.

The disclosure describes various stackable corner protector configurations. The corner protectors can have curved lateral surfaces that allow the corner protectors to be decoupled from a photovoltaic module to which they are coupled to by rotating one end of the corner protectors away from the object. This removal process works even more efficiently with multiple stacked corner protectors as the stacked corner protectors can be concurrently removed from the object by rotating the stacked corner protectors away from the object together. The corner protector can also include one or more attachment features for securing the corner protector to the object. For example, when the corner protector is installed on a photovoltaic module, the attachment feature can engage a lip defined by a recess or channel of the photovoltaic module.

A spacer (100) for spacing two adjacent stacked solar modules (101a, 101b), the spacer (100) comprising: a body (108) having spaced opposed first and second edges (110, 109), the body (108) comprising an upper contact surface (111) for contact with an upper solar module (101a), and a lower contact surface (112) for contact with a lower solar module (101b); a first upper protrusion (114) arranged to bear against a frame (102) of the upper solar module (101a), the first upper protrusion (114) protruding upwardly from or proximate to the first edge (110) of the body (108) to a free end of the first upper protrusion (114); and a first lower protrusion (118) arranged to bear against a frame (102) of the lower solar module (101b), the first lower protrusion (118) protruding downwardly from or proximate to the first edge (110) of the body to a free end of the first lower protrusion (118), the first lower protrusion (118) offset from the first upper protrusion (114) in a direction along the first edge (110).

Mounting components of photovoltaic (PV) modules and PV module assemblies are described, including PV module couplings and PV module mounting chassis. In an example, a PV module includes a PV module coupling having a toe portion extending from a PV module frame, and a PV module mounting chassis includes a toe slot to receive the toe. The toe and toe slot construction allows for the PV module frame to be assembled to the PV module mounting chassis without using tools, and thus, permits a PV module assembly to be quickly constructed during installation of a PV module system. Furthermore, the toe and toe slot construction accommodates thermal expansion and other environmental loads seen after installation, while providing a grounding connection for the PV module assembly.

The invention relates to a pile-driving profile, preferably for an outdoor solar installation, comprising a main body and two limbs extending from the main body, wherein the limb ends are each bent inwards and form a stack stop for stacking with a further pile-driving profile.
