Definitions

  • the present invention relates to a system for mounting photovoltaic panels.
  • the present invention relates to a system that provides for fast attachment and removal of photovoltaic panels from a support structure.
  • PV modules also known as solar panel modules
  • PV modules are typically mounted to support structures and include a photovoltaic panel and the associated electrical wiring for connecting the module to a desired circuit.
  • PV modules are typically installed on the roofs of buildings or homes in order to place them in the best position for receiving the direct and uninterrupted sunlight that is necessary to generate electricity.
  • mounting the modules on such structures can be difficult since they need to be properly aligned in order to work most efficiently and also to be more aesthetically pleasing.
  • PV modules are mounted on a support structure that typically consists of a plurality of spaced elongate rails.
  • the rails are designed to accommodate one or more PV panels along their length.
  • Such rails must be properly aligned and spaced from each other in order to provide a mounting surface and attachment points that correspond to the mounting apertures in the PV module. If one rail is not parallel to the other and spaced appropriately from the other to provide the correct amount of support for the module installation, the attachment points will not align with the mounting apertures in the PV panels.
  • rails may have to be adjusted in length to accommodate a particular installation. Therefore, a significant amount of time and effort must be expended on top of a roof to install and align the rails.
  • the installation of the PV panel systems on the roofs of structures can be a time consuming operation and a significant part of the cost for an owner.
  • the support structure has to be attached to the roof and then each panel must be secured to the support structure using a plurality of fastening devices. Therefore, anything that reduces the installation time reduces the overall cost of the PV panel system. Since a large number of fastening devices are used to secure the PV panels to the support structure, reducing the time needed for installing the fastening devices would reduce the overall time required for installing the PV panel system.
  • a photovoltaic panel mounting system comprises, consists of or consists essentially of a pair of spaced mounting rails, one or more fastener retaining devices and a plurality of quick access fasteners.
  • Each of the pair of spaced mounting rails includes a first end, a second end and a plurality of mounting holes.
  • the one or more fastener retaining devices are aligned with the plurality of mounting holes in each of the rails.
  • Each of the quick access fasteners is removably secured to one of the rails through one of the plurality of mounting holes.
  • the quick access fasteners are securable and removable to one of the one or more fastener retaining devices with less than one revolution of the quick access fastener.
  • the plurality of the quick access fasteners can be quarter turn fasteners and they can have a head with a shaft extending therefrom to a distal end.
  • the one or more fastener retaining devices includes a rod extending along the length of the rail or a pin in the rail located at each of the plurality of mounting holes.
  • the quarter turn fastener has an engaged position and a disengaged position. When in the engaged position, the fastener, preferably a notch at the distal end, engages the rod and the fastener is secured to the mounting rail. When in the disengaged position, the fastener does not engage the rod and the fastener is not secured to the mounting rail.
  • Each of the spaced mounting rails is elongated and has a base, first and second side walls extending upwardly therefrom and one or more top plates; preferably first and second top plates.
  • the side walls can be substantially parallel or they can extend from the bottom wall to the top plate at an angle to provide additional structural strength.
  • the side walls and the bottom wall and top plate have a trapezoidal shape, when viewed form one of the ends of the rail.
  • the first and second top plates extend inwardly from the side walls and parallel to the base to define an interior.
  • the plurality of mounting holes is formed in the first top plate.
  • each of the pair of spaced mounting rails can include a passage having a first end and a second end
  • the passage is located in the interior and is in communication with the plurality of mounting holes.
  • the one or more fastener retaining devices are positioned in the passage; most preferably, the rod is positioned in the passage.
  • the rod can also be attached to the rail by a plurality of clips that attach to a lip on the top wall of the rail.
  • each of the pair of spaced mounting rails has a first end, a second end, a bottom wall, a top plate and one or more side walls therebetween.
  • the bottom wall, top plate and one or more side walls define an interior and an exterior and the top plate has a plurality of mounting holes.
  • the one or more fastener retaining devices preferably a rod extending the length of the passage, are located in the interior and align with the plurality of mounting holes in each of the rails.
  • the passage is in communication with the exterior through the plurality of mounting holes.
  • the passage is formed by two curved walls extending from the top plate into the interior.
  • FIG. 1 is a perspective view of the photovoltaic mounting system shown secured to a roof of a structure.
  • FIG. 2 is a detail view of the mounting system of FIG. 1.
  • FIG. 3 is a side elevational view showing a PV panel mounted to a rail.
  • FIG. 4 is a top perspective view showing a mounting rail and a fastener retaining rod prior to insertion in the passage.
  • FIG. 5 is a partial top view of a rail PV panel mounting hole.
  • FIG. 8 is an exploded side elevational view.
  • FIG. 9 is a side elevational view showing a mounting rail with a fastener therein;
  • FIG. 12 is an end perspective view of an embodiment of the mounting rail that uses a nut captured in a track in the rail.
  • FIG. 15 is a perspective view of a clip.
  • FIG. 16 is an end view of the rail of FIG. 14 with a panel secured thereto.
  • FIG. 22 is a side elevational view of the clip of FIG. 20.
  • the pair of rails is positioned on a structure, such as a roof, and spaced apart so that the mounting holes in the top plates of the rails correspond with the mounting apertures in the photovoltaic panel.
  • the rails are then secured to the structure and, in a preferred embodiment, a rod is inserted into the passage located on the interior side of the top plate.
  • the passage is in communication with the plurality of holes in the top plate.
  • the solar panel is then positioned on the pair of rails so that the mounting apertures in the photovoltaic panel are aligned with the holes in the top plate.
  • one or more insulators can be positioned between the top plate of the rail and the photovoltaic panel.
  • the quick access fasteners are then inserted in the mounting apertures of the photovoltaic panel, pass through the optional insulator and holes in the top plate of the rail.
  • the quick access fasteners are then rotated in the clockwise direction, preferably one -half turn, more preferably one-quarter turn to engage the rod in the passage and secure the photovoltaic panel to the mounting system.
  • the photovoltaic panel can be quickly and easily removed from the mounting system by rotating the quick access fasteners in a counter-clockwise direction or by removing the rod from the passages in the pair of mounting rails.
  • the head 36a of the fastener 36 is pressed down to compress the pad 42 and then turn the fastener 36 toward the open or unsecured position.
  • the fastener 36 may be removed and the PV panel 14 then lifted off the mounting rail 12.
  • the resilient pad 58 may extend along the entire length of the rail 12 or alternatively, there may be multiple pads 58 each extending only a certain distance on either side of the mounting hole. When the panel 14 is secured by the fastener 36, the resilient pad 58 is compressed which helps to retain the fastener 36 in the secured position as described above with regard to the embodiment shown in FIGs. 3-4.
  • the receptacle 64' may be of a type having clips 66 which are inserted through a square opening formed in the top of the rail to receive the receptacle 64'.
  • the receptacle 64' is held in place by the clips 66 formed thereon.
  • the rod 34 may be held in place on a rail 100 by clips 102.
  • Rail 100 may have a generally C-shaped configuration and include a central wall 104 extending along its length bounded by opposed channels 106. Each channel includes a channel wall 108 ending in a lip 110.
