Definitions

  • the present invention relates to a mounting system for mounting solar panels, as well as to a fastening device, a mounting rail, and a capping rail designed for use in such a mounting system. Furthermore, the invention also contemplates a new frame structure for solar panels, with the frame members incorporating features from the capping rail of the new mounting system.
  • the mounting system of the invention and, of course, the associated fastening device and the mounting rail and capping rail are particularly suitable for use in mounting solar panels on a pitched or sloping roof or similar structure, and it will convenient to describe the invention in this exemplary context. It should be appreciated, however, that the mounting system of the invention is not limited to use on rooftops or sloping surfaces, but may also be employed where solar panels are to be mounted on any of a variety of supporting structures.
  • PV photovoltaic
  • the solar panels are often mounted on the rooftops of buildings - most typically in the area where the solar energy is required. Roof structures are particularly convenient for this purpose as they present a large surface area directed towards the sun, which is both out of the way and often largely out of view from the normal visual perspective, thereby rendering the installations relatively unobtrusive. Horizontal or flat rooftop surfaces are naturally convenient for workers assembling and installing an array of solar panels as they provide an even and stable working environment. Many roof structures, however, are not horizontal but rather are pitched or angled, and thereby present significant challenges for the workers installing the solar panel array.
  • the solar panels are typically provided as photovoltaic (PV) modules, each of which usually comprises a laminated glass panel incorporating a multitude of photovoltaic cells.
  • the glass panel is often surrounded by a metal frame, which not only protects the edges of the glass, but also provides a robust structure for use in mounting the panels. While some manufacturers also produce cheaper solar panels that dispense with the metal frame around the panel edges, the highest quality modules having the highest solar efficiency remain framed panels.
  • Individual framed PV solar panels are produced in various sizes, but they typically have a solar collecting area in the range of about 0.5 m 2 to about 6 m 2 .
  • One particular example of such a PV solar panel has dimensions of about 1 .6 m x 1 .0 m and a mass of about 25 kg.
  • the solar panel mounting system should provide an easy and efficient installation procedure that can be performed by a single person, and that minimises the risk to the health and safety of the person performing the installation, e.g. on a pitched roof or an angled structure, as well as to the health and safety of bystanders in the vicinity.
  • the present invention provides a mounting system for mounting solar panels on a support structure, such as a roof, the system comprising: a mounting framework having a plurality of elongate mounting members adapted to be arranged and secured spaced apart and substantially parallel to one another, with each of the mounting members being adapted to receive and support an edge region of a solar panel such that each solar panel extends between two spaced apart and substantially parallel mounting members.
  • the mounting system includes a plurality of fastening devices for securely fastening the solar panel to the mounting members, with each of the fastening devices comprising a clip component for attachment to a respective one of the mounting members, and a clamping member provided on or carried by the clip component for engagement with an edge region of the solar panel.
  • the fastening device is configured to bias or press the clamping member with respect to the clip component so as to clamp and securely hold the solar panel in position on the respective mounting member.
  • the clamping member is configured to be biased, drawn or pressed towards the clip to clamp and hold the solar panel in position.
  • the clip component of the fastening device is configured for clipped or snap-fit attachment to the respective one of the mounting members.
  • the clip component (also simply called "clip") of the fastening device may provide a significantly faster and easier of assembly of the mounting system and solar panel array as the fastening devices may be positioned on, and attached to, the respective mounting members quickly and reliably without the need for special tools. That is, the attachment of the clip component may desirably be performed by hand (i.e. without use of a tool) with the clip designed to simply 'slot' or 'click' into place to provide a robust and reliable connection with the mounting member for clamping the solar panel thereto using the clamping member.
  • each of the fastening devices typically includes an operating member which is adapted to bias or apply pressure to the clamping member with respect to the clip thereby to impart a clamping force to the solar panel.
  • the operating member may connect the clamping member with the clip component and may be adapted to apply the bias or pressure to the clamping member incrementally.
  • the operating member may include screw means for effecting a threaded connection between the clamping member and the clip component.
  • the operating member may comprise a threaded bolt which interconnects the clamping member and the clip. The head of the bolt may bear upon the clamping member, with the threaded shaft of the bolt in threaded engagement with the clip, or vice versa.
  • the screw thread may operate to bias or to press the clamping member incrementally to effect the clamping engagement with the edge region of the solar panel.
  • the clamping member may comprise a plate-like member and is preferably designed to engage the edge regions of two solar panels at opposite ends or sides thereof. That is, opposite end or side portions of the clamping member may be configured to engage a respective framed edge region of a solar panel. Furthermore, the clamping member may have a hole or aperture for receiving the operating member.
  • each mounting member is an elongate structural element, such as a beam or "rail", upon which the solar panels are mounted and supported within the framework of the mounting system.
  • each mounting member or mounting rail has laterally opposite, longitudinally extending panel seating areas formed at an upper side thereof.
  • Each of these panel seating areas is adapted to receive and support an edge region of a solar panel, with each panel seating area extending substantially parallel to the edge region of the solar polar to be received thereon.
  • each mounting member or mounting rail also includes means for attaching a clip component of one or more of the fastening devices between the laterally opposite panel seating areas.
  • the attaching means may include engagement elements, e.g.
  • the means for attaching the clip comprise a longitudinally extending channel that opens to an upper side of the mounting rail, and the channel incorporates engagement elements to engage and retain the clip in a snap-fit attachment, e.g. when part of the clip component is inserted into the channel.
  • the clip component includes at least one catch member configured to engage and/or interlock with a corresponding engagement element of the respective mounting rail in the attached state to prevent the clip from separating from the mounting rail when the clamping member is biased or pressed with respect to the clip.
  • the at least one catch member may comprise a projection, for example in the form of a hook or barb, for engaging and/or interlocking with a complementary profile element of the respective mounting rail. That profile element is preferably a flange or shoulder projection.
  • the clip includes at least one limb, and more preferably, a pair of limbs, with each limb having said at least one catch member.
  • the limb(s) of the clip is/are desirably also resiliently deformable or deflectable for effecting a snap-fit or 'click-in' attachment to the mounting rail, e.g. in the upwardly open channel located between the laterally opposite panel seating areas, as noted above.
  • the clip component has a connection member which is configured to receive and engage with the operating member, and thereby serves to connect the clip with clamping member.
  • the connection member may include a recess or aperture for receiving the operating member and preferably also includes thread means for threaded interaction with the operating member, as described above.
  • the connection member extends between and/or interconnects the limbs of the clip component.
  • connection member has a plate-like form, with each limb of the clip depending from the connection member. Each limb may also have a plate- or strip-like form.
  • the clip is configured to at least partially define a limit or boundary to the panel seating areas on the mounting member and/or to form a spacer between the panel seating areas. That is, when the clip is attached to the mounting rail, a body portion of the clip at least partially separates those panel seating areas.
  • the body portion of the clip presents surfaces that define a limit or boundary of each of the panel seating areas on the mounting member, with each limiting surface of the clip to be located or positioned adjacent a peripheral edge of a solar panel that is seated and fixed on the mounting member. The clip may thus limit the extent to which the edge region of the solar panel may be received on the upper side of the mounting member.
  • the clip component of each fastening device is, in the attached state, movable in a longitudinal direction along the mounting rail to which it is attached. That is, the clip component may be configured for slotted or snap-fit attachment to the mounting rail with sufficiently little retained or residual tension to allow the clip to be moved longitudinally without application of an undue force. This may assist the person assembling the solar panel array to properly place and position the fastening devices.
  • each mounting rail includes a longitudinal channel configured to receive and engage and/or interlock with the clip component of each fastening device in clipped or snap-fit attachment therewith, the clip component could potentially be moved, e.g. slid, axially along that channel to ensure the fastening device is in the desired position. The ease of doing so will be dependent upon the degree of resilient tension retained in the clip after its clipped or snap-fit attachment to the mounting rail, as will be explained in more detail later.
  • the mounting system further comprises a lateral support member configured to support the clamping member of the fastening device at a laterally outer periphery of the solar panel array.
  • the lateral support member is adapted to be positioned in a panel seating area on the mounting rail in place of the edge region of a solar panel, as no further solar panel is present at an outer periphery of the array.

This lateral support member or support rail may also include one or more abutment elements against which the clamping member of the fastening devices can directly bear.

  • this embodiment of the solar panel mounting system 100 has been designed to be integrated into the rooftop in such a way that the roof cladding, which was removed over the area of the solar panel array to expose the roof beams, does not need to be replaced or substituted. That is, in the mounting system 100 of the invention, the solar panels S themselves can effectively form a weather-resistant part of the building envelope without separately or additionally covering and sealing the rooftop area covered by the solar panels with a weather-proof layer. In other words, the mounting system 100 has been developed so that the solar panels S are able to guide rainwater and/or snow-melt over the roof area without permitting any significant ingress of water into the roof space below. With reference now to Figs.

  • Figs 4 and 14 the configuration of the mounting rail 20 and the manner in which the respective edge regions E of the solar panels S are received on the mounting rails 20 will be described. As shown in Fig.
  • the mounting rail 20 comprises two seating areas 21 formed at an upper side thereof.
  • Each of the seating areas 21 is adapted to receive and support the edge region E of a solar panel S, with each of these two panel seating areas 21 extending along the length of the mounting rail 20 parallel to the edge region E of the solar panel it receives and supports.
  • the width of each of the panel seating areas 21 and correspondingly, therefore, the width of the edge region E of each solar panel S to be supported and fixed to the mounting rail 20 is typically in the range of about 10 mm to 50 mm, and preferably in the range of about 20 mm to 40 mm.
  • the overall width of the mounting rails 20 i.e. the width dimension of the cross-section shown in Fig. 14

  • the rectangular strip of each seating element 25 has an overall width which is essentially the same as the width of the respective panel seating area 21 and extends in each case from an inner side of inner flange 23 to an outer edge of the outer flange 22.

An upper end or rim of one of those channel walls 27 has an inwardly projecting flange or lip 28 which is formed with and/or terminates in a curved or rounded bead.
  • the opposite channel wall 27 also has an inwardly projecting flange or lip 29 at an upper end or rim thereof, but this time it forms a short barb-like edge in the profile view of Fig.
  • each flange or lip element 28, 29 at the upper rim of the channel 26 extends longitudinally along the length of the mounting rail 20, just like the channel 26 itself.
  • the purpose and operation of these elements 28, 29 will be explained in detail with reference to Figs. 4 and 5 of the drawings.
  • the mounting system 100 includes a plurality of fastening devices 30 for securely fastening the solar panels S to the mounting rails 20. Indeed, as is apparent from Fig. 1 , a number of fastening devices 30 may be employed along the edge regions E of each of the solar panels S. After the solar panels S have been properly placed and positioned on the seating elements 25 of panel seating areas 21 spanning two parallel mounting rails 20, the fastening devices 30 are employed to clamp and securely hold the panels in those positions on the associated mounting rails 20. Stated briefly, and visible in Fig. 4, each of the fastening devices 30 includes a clip component 31 which is configured for clipped or snap-fit attachment to the mounting rails 20, and a clamping member 41 which is configured to clamp and securely hold the solar panel S in position on the respective mounting rail.
  • the clip component 31 in this embodiment is (like the mounting rails 20) formed as a metal (e.g. aluminium) element of constant cross-section.
  • each clip component 31 has a pair of opposed limbs 32 (e.g. legs) which depend from a central, substantially flat plate member 33.
  • plate member 33 interconnects the pair of opposed limbs 32.
  • each of the limbs or legs 32 has an outer surface 34 which is substantially flat and extends generally perpendicular to the plate member 33.
  • the free end of one of the limbs 32 is angled inwardly somewhat from the upper surface 34 and terminates in a curved or rounded hook-like catch member 35.
  • the free end of the other limb or leg 32 is set slightly inwardly of the upper surface 34 and terminates in a tapered barb-like catch member 36.
  • the clip component 31 is designed for attachment in the upwardly opening main channel 26 of the mounting rails 20, and the manner in which the clip 31 operates and interacts with that channel 26 can be seen in Fig. 5.
  • the clip components 31 are attached to the mounting rails 20 at positions spaced apart along the channel 26.
  • the curved, hook-like catch member 35 at the end of one limb 32 of the clip component is hooked under the bead of the inwardly projecting flange or lip 28 at one side of the channel 26 and then the clip 31 is pivoted to bring the tapered barb-like catch member 36 at the free end of the other limb 32 into engagement with the inwardly angled edge profile of the flange or lip 29 at the opposite side of the channel 26.
  • the tapered outer surface 37 of the barb-like catch member 36 contacts the inwardly angled flange or lip element 29, the resiliently deformable limb 32 is deflected inwardly towards the hook 35 as the clip is rotated (by hand) in the direction of arrow R in Fig. 5.
  • the limb or leg 32 snaps back under its own elasticity, with the barb-iike edge of the flange or lip element 29 at the upper rim of the channel 26 then being held within the longitudinal slot or recess 38 formed adjacent the catch member 36 in the clip.
  • the hook and barb catch members 35, 36 on the resilient limbs 32 of the clip component 31 have interacted or interlocked with the engagement elements 28, 29 of the channel 26 to secure the clip 31 to the mounting rail 20. Because this snap-fit attachment of the clip 31 can be effected by an operator by hand, a speedy assembly of the mounting system 100 is promoted.
  • the degree of residual tension in the limbs 32 of the clip component after the snap-fit attachment to the mounting rail 20 can be adjusted by appropriate selection of the dimensions and the material of the clip 31 . Desirably, however, a certain amount of resilient tension remains in the clip in the attached state (i.e. some resilient deformation is retained) to ensure that the clip maintains a reliable interlocked connection with the mounting rail 20 and does not readily slip out of position along the channel 26 of the mounting rail 20 which is pitched at the angle of the rooftop. It may, however, be possible to slide the clip along the channel 26 upon the application of some force (perhaps with the assistance of a tool) if it becomes necessary to alter its position. Additionally, the clip may be removed from its engagement with the channel 26 by the application of an appropriate force, e.g.
  • the outer surfaces 34 at the upper part of each leg 32 are approximately aligned with respective outer surfaces of the channel walls 27.
  • the body of the clip 31 i.e. formed by the upper parts of the limbs 32 and the plate member 33
  • the body of the clip component 31 acts to partially limit or bound the panel seating areas 21 on each mounting rail.
  • each of the surfaces 34 at the upper part of the limbs 32 of the clip limit and abut the frame F at a peripheral edge of the solar panel S, as can be seen in Fig. 4 of the drawings.
  • the upper outer sides of the channel walls 27 also abut and engage the frame F of the solar panels in the seating areas 21 .
  • the clip component 31 as spacer and abutment member between the peripheral edges of the solar panels S, the proper placement and positioning of the panels is simplified and can occur more quickly.
  • the fastening devices 30 are then assembled and used to securely fix and hold the solar panels S in position within the array.
  • the clamping member 41 referred to previously is positioned above the clip component 31 such that stepped wing portions 42 at opposite ends of the clamping member 41 sit or rest on an upper side of the frame F over the edge regions E of the two solar panels S received in the two seating areas 21 of the mounting rail 20, and a central plate-like portion 43 of the clamping member 41 is positioned above the correspondingly dimensioned plate member 33 of the clip 31 .
  • a threaded bolt 44 is provided through a hole 45 formed in the central plate-like portion 43 of the clamping member 41 and extends into a threaded socket or bore 40 provided in the clip 31 .
  • the threaded socket 40 is provided attached to a hole or aperture 39 formed in the plate member 33, e.g. by riveting.
  • the plate member may for example be formed with greater thickness and the hole or aperture 39 provided with an internal thread.
  • each fastening device 30 clamps and securely hold the solar panel S in position on the respective mounting rail 20, and by arranging a number of fastening devices 30 along the edge region E of each solar panel S, the clamping force can be distributed along that edge region.
  • each mounting rail 20 at the lateral outer periphery of the array receives and carries a solar panel at only one of its two panel seating areas 21 .
  • the stepped wing portions 42 of the clamping member 41 engage the upper side of each solar panel S at a height in the range of about 30 to 50 mm (corresponding to the height of the frame F) above the mounting rail 20 and spaced slightly to one side of the bolt 44.
  • the fastening device 30 would tend to twist or turn outwardly away from the solar panel under the action of the clamping force via the threaded bolt 44, i.e. as a result of a moment generated by the force.
  • the mounting system 100 includes a lateral support rail 50 that is designed to be received in the laterally outermost panel seating area 21 of the array.
  • This lateral support rail 50 is again a metal section, e.g. of Al. extruded, which is generally formed as a U-shaped channel section having two upright walls 51 , but which also has two webs 52 extending vertically downwardly from a base 53 of the channel section and a small lateral flange or web 54 extending laterally from the outer of the two downward webs 52.
  • the small lateral flange or web 54 is configured to seat and bear against the outer flange 22 of the panel seating area 21 , while the downwardly extending webs 52 are received in the channel 24 of the seating area 21 .
  • the lateral support rail 50 includes one or more abutment elements 55 which are provided in the form of flat-headed studs or bolts.
  • These flat-headed stud or bolt elements 55 are not only displaceable (e.g. slidable) along the support rail 50 but are also vertically adjustable, e.g. via a screw thread, to accommodate height variations which depend upon a height of the particular frame F of the solar panels S mounted in the solar panel array.

  • Each capping rail 60 has two generally parallel web members 64 which depend from the cover plate 61 to form a vertical channel there-between. As can be seen, these web members 64 are configured to cooperate with a bracket member 70 for securing the capping rail 60 to the frame F along the transverse edge of one of the solar panels S.
  • the bracket member 70 has two parallel upstanding flange members 71 configured to receive the parallel depending web members 64 of the capping rail 60 between them. Further, the bracket member 70 receives a threaded clamping bolt 72 in a hole or aperture 73 formed through a base 74 thereof such that the bolt 72 extends vertically into the channel formed between the depending web members 64. Between the parallel depending web members 64, the capping rail 60 has a longitudinal slot 65 which is formed by pairs of opposing projections 66. This slot 65 is designed to receive a nut or retainer 76 for the clamping bolt 72 that operates with the bracket member 70 in such a manner that the nut 76 is displaceable longitudinally of the capping rail 60 in a direction L along the slot 65 when positioning the bracket member70.

  • the bracket member 70 may cooperates with the capping rail 60 to be adjustable in the height direction h to suit different sized panel frames F.

  • one side or edge 67 of the cover plate 61 i.e. that side or edge which is not clamped against the frame F

  • that longitudinal edge 67 of the cover plate 61 is free to overlap an adjoining panel.
  • the transverse edge region of each panel having the capping rail 60 is arranged as the lower edge in the inclined array.
  • the free edge 67 of the cover plate 61 in the capping rail 60 then overlaps and overlies the upper edge region of the frame F of the adjoining solar panel S in the array. While the capping rail 60 is not directly clamped to the adjoining solar panel S, the presence of the sealing strip element 62, together with the attachment of the solar panels to the mounting rails 20 via the fastening devices 30, nevertheless creates a satisfactory seal with those adjoining panels. In this manner, the capping rails 60 in the mounting system 100 of this embodiment ensure the integrity and continuity of rainwater run-off and drainage so that the solar panel array may effectively function as part of the building envelope.
  • the capping rails 60 direct rainwater for the upper surface of one solar panel onto the upper surface of an adjoining panel in the array and prevent the ingress or penetration of water between the adjoining transverse edge regions of the solar panels by covering and sealing these regions of the array.
  • the unwanted infiltration of rainwater, snowmelt or condensate into the roof cavity or roof structure is essentially inhibited.
  • flashing material G is provided to ensure a weather-proof transition between the original roof cladding and the solar panel array installed in the area where the cladding was removed.
  • Fig. 1 of the drawings for example, a section of flashing sheet material G is illustrated at the high side H of the array.
  • the mounting system 1 00 also includes a modified capping rail 60' for the edge region of the solar panels S at the upper periphery of the array.
  • the modified capping rail 60' incorporates a cover plate 61 and the same securing arrangement via bracket member 70 as the capping rail 60 just described.
  • the primary difference in this case is the provision of a retaining slot 68 above the cover member 61 for receiving and retaining an overturned edge region N of the flashing sheet material G.
  • the capping rail 60' is again an extruded section, but this time includes a curved C-profile 69 formed above the cover member 61 to create the retaining slot 68, which is thus formed as a blind slot.
  • the opening O of the slot 68 is directed towards the upper surface of the solar panel S to which the capping rail 60' is attached, which in turn requires the edge of the flashing sheet G to be overturned to be inserted into the slot. In this way, any rainwater run-off tends to flow off the edge N of the flashing and directly onto the upper surface of the panel S. If some water does flow into the slot 68, however, the closed or "blind" slot 68 does not allow the water to flow anywhere other than back out though the opening O.
  • the features of the cover plate 61 and the retaining slot 68 could also desirably be integrated directly into new frame members F for the framed PV modules. In this way, it would not be necessary to retro-fit the capping rails 60, 60' to the solar panels S as elements of the mounting system 100. Instead, they would already be integral with the solar panels themselves. For this reason, the present invention also contemplates a frame member for a PV solar panel having features of the cover plate 61 and/or the retaining slot 68 described above in connection with the capping rails 60,60'.
