Discrete attachment point apparatus and system for photovoltaic arrays
An attachment point apparatus and system for photovoltaic arrays is disclosed. One embodiment provides a rail system for receiving a PV module, including a first rail, a second rail, a substantially rectilinear double male connector adapted for coupling an end of the first rail to an end of the second rail, and a connector adapted to attach a PV module to the first rail. Another embodiment provides a PV module including a PV laminate, a frame integral with and supporting the PV laminate, and a spanner bar adapted to solely span a width of the PV module, orthogonally connect at various locations along the frame, and attach to a support structure. A further embodiment provides a coupling device for a PV module comprising a first coupling portion adapted to rotatably engage a PV module, and a second coupling portion adapted to rotatably engage a rail.
1. A photovoltaic module (PV) mounting system, comprising:
a first PV module;
a second PV module adjacent to the first PV module;
a section of rail defining a groove;
a PV module connector supporting the first and second PV modules above the section of rail, the PV module connector comprising a pair of opposing male connector portions engaged within respective channels formed in frames of the first and second PV modules, each frame extending around a periphery of a respective one of the PV modules; and
a cam portion having a cam lobe that in a first position fits in a groove formed in the top of a section of rail, and in a second position locks into the groove formed in the section of support rail; and
a threaded stud that interconnects the PV module connector and cam portion, the threaded stud at one end passing through a threaded opening in the PV module connector,
wherein an elevation of the PV modules above the section of rail changes when the PV module connector rotates relative to the threaded stud after the cam portion has been attached to the section of support rail wherein the PV module connector is elevated entirely above the section of rail.
2. A photovoltaic (PV) mounting system, comprising:
a first PV module;
a second PV module adjacent to the first PV module;
a section of rail defining a groove;
a PV module connector supporting the first and second PV modules above the section of rail, wherein the PV module connector comprises opposing first and second male PV module connector portions engaged with respective frames of the first and second PV modules;
a threaded stud having a first end engaged within a threaded opening defined by the PV module connector; and
a base connector coupled to the threaded stud and having a foot that in a first position fits into the groove and in a second position locks into the groove,
wherein the PV module connector is elevated entirely above the section of rail and an elevation of the PV modules above the section of rail changes when the PV module connector rotates relative to the threaded stud when the base connector is positioned within the groove.
3. The PV Mounting system of claim 2 , wherein the base connector further comprises a grounding feature that cuts into and is engaged within a portion of the section of rail.
4. The PV mounting system of claim 2 , wherein a shape of an upper portion of the groove is substantially similar to a shape of the foot of the base connector.
5. The PV mounting system of claim 2 , wherein a first portion of the base connector engages the groove and a second portion of the base connector protrudes out of the groove.
