- the base support 100 is the first piece of the wire management system 1 to be installed, supports the entire system, and allows water to flow under the tray 200 and cover piece or cap 300 when the latter two elements are coupled to the base support 100 .

- the base support 100 includes a planar base 101 that is mountable upon the roof 3 and is integrally connected with a pair of vertical side panels 103 extending substantially perpendicularly and upwardly therefrom.
- Each side panel 103 includes an internally facing side panel face 105 and an externally facing side panel face 107 .
- Each side panel 103 has an opening 109 to receive the wires 7 from the PV panel 5 .
- the internally facing side panel faces 107 include a ledge 111 , preferably substantially L-shaped with the short leg 113 of the ledge 111 extending in an upward direction from the longer leg 115 .
- the ledge 111 extends the entire length of the base support 100 and lies above the holes or openings 109 in the side panels 103 .
- the openings 109 receive the wires 7 .
- each vertical side panel 103 At the upper or free end 117 of each vertical side panel 103 is an interlocking edge member 119 that extends outwardly from the externally facing side panel face 105 .

- each wing member 121 includes a perpendicular or vertical edge as shown 123 .
- the wing 121 can be formed without any edge, but extends completely angularly downwardly so as to rest upon the PV panels 5 .
- Each wing member 121 is intended to overly and protect the wire junction that extends from the PV panel 5 .

- An elongated tray 200 fits between the upright base support side panels 130 and is supported by the ledges 111 extending inwardly from the side panels.
- the elongated tray 200 is sized so as to overly the plural base supports. It has been found that a tray having a 20 foot length may be effectively utilized with plural base supports numbering between 10 and 20, preferably 15 , depending upon the number of photovoltaic devices protected. Each photovoltaic panel or panel pair should have a single base support adjacent thereto. Generally the spacing between adjacent base supports is greater than the length of the base supports. As previously discussed, there may be circumstances where the length of the tray 200 and cover piece 300 are each shorter and may be installed in components, rather than one long piece for each element.

- the holes/openings 207 are formed on site adjacent the location where each of the wires or wire sets 7 enter the base supports 100 . Because the base supports 100 may not be precisely evenly spaced in the longitudinal direction, it cannot be determined in advance where the holes 207 in the tray 200 should be located. On the other hand, there may be circumstances where a single elongated base support is utilized in which case the openings within the tray may be pre-drilled. Both of these possibilities are within the scope of the present invention.
- the openings 207 to be cut in the bottom 201 of the tray 200 are substantially aligned with the openings 109 of the base supports 100 so that the wires 7 from the PV panels 5 , after being threaded through the openings 109 of the base supports 100 , may be threaded upwardly and outwardly within the tray 200 .
- the elongated cap or cover piece 300 for covering the tray 200 and interlocking with the base supports 100 will now be described.
- the elongated cover piece 300 is preferably of the same length as the tray 200 and is formed in a single section (or plural sections fit adjacent to each other) to provide a complete cover for the base supports 100 and tray 200 .
- the cover piece 300 includes a top portion 305 generally planar, although other shapes are certainly within the scope of the present invention.
- the top portion 305 could be cylindrical, i.e., semi-circular in cross-section.

- Each of the vertical side walls 307 has a free edge 309 that defines an interlocking lip for interlocking with the interlocking edge member 119 of the plural base supports 100 .
- the cap or cover piece 300 is the final piece of the wire management system that ties the system together and protects the wires from the elements. It is the tray 200 that carries all of the wires and connectors for the PV system protected by the cover piece 300 .
- the space between the bottom 201 of the tray 200 and the plural base supports 100 provides a conduit for water to flow under the tray 200 and cap 300 .
- the PV laminate panels 5 are installed on the roof 3 aligned with adjacent panels and spaced apart a distance sufficient to enable the base supports 100 to be fitted therebetween.
- the base support 100 is approximately three inches wide, it is suggested that the PV panels be spaced apart approximately four and one-half inches.
- each of the plural base supports 100 is placed on the roof 3 at a location where the holes 109 will be adjacent, or as close as possible, to where the wires 7 , potted to the panels 5 , are located.
- the base supports 100 will be spaced an equal distance from each other, but this is not required.
- the positioning of the base supports 100 depends upon the positioning of the laminate panels 5 and must be adjacent to the panels 5 such that the wires 7 from the panels can be threaded through the openings 109 of the base supports 100 .
- the roof 3 is first generally cleaned with a solvent so that the base supports 100 can be heat welded, taped or glued to the roof by the roof membrane 11 in a secure manner. This is shown in FIG. 3 where strips of roof membrane 11 are heat welded to secure the base supports to the roof.
- the wires 7 from the PV panels are threaded through the openings 109 of the base supports as shown in FIG. 4 .
- the elongated tray 200 is generally positioned to overly the base supports and the wire locations are marked on the bottom 201 of the tray 200 so that a hole 207 , such as a one inch hole, is drilled or cut out in the tray bottom 201 to allow the group of wires 7 to pass therethrough. See FIG. 6 . (Only one hole 207 is depicted, but the location of the other holes, as marked by the installer on site, is shown and will be the location of the other holes.)
- the tray 200 is positioned to be supported by the base supports 100 and the wires 7 that had been threaded internally within the base supports are threaded upwardly through the holes 207 of the planar base 201 .
- the wires 7 that are shown in FIG. 7 as loosely supported by the tray 200 are ultimately connected to further components of the electrical system that receive the power generated by the PV panels.
- the next step in the method is the securing of the cover piece or cap 300 to overly the tray 200 and protect the wires 7 , as well as to secure the cover piece 300 to the base supports 100 to provide a firm interlock.
- This is shown in FIG. 8 .
- the width between the vertical side walls 307 of the cover piece 300 is substantially the same width as the width between the side panels 103 of the base supports 100 so that, as the cover piece 300 is pressed downwardly from above, after the tray 200 is supported by the base supports 100 , the walls 307 of the cover piece 300 and side panel walls 103 of the base supports 100 will flex sufficiently to provide a snap interlock connection therebetween.

Description
- 1. Field of the Invention
- The present invention relates to a wire management system and system components for protecting wires originating from roof-mounted solar panels such as photovoltaic (“PV”) laminated panels. The invention further relates to a method of installing the wire management system adjacent the roof-mounted PV laminated panels.
- 2. Description of the Related Art
- Solar panels, such as PV laminated panels, mounted to roofs are well known in the art. Such panels necessarily include a plurality of wires that are connected to the PV panels and then routed into electrical components, such as storage batteries or converted to alternating current for use in an electrical utility grid. Conventional methods of mounting PV panels may involve drilling of holes into or through the roof of a building. The various wires connected to the PV panels may also be routed through holes or openings within the roof.
- A need has arisen for a wire management system to protect the wires from the environment, such as rain and solar ultraviolet rays, and to keep the roof neat, clean, and free of haphazardly-arranged loose wires, without penetrating the roof. A need has arisen for such system to be easily installed and to ensure a safe roof environment.
- The wire management system of the present invention is a UV-protected system to protect the wires and to keep the roof neat, clean, and free of loose wires without penetrating the roof. The wire management system is preferably a three-piece system consisting of (1) a base support, preferably plural base supports, that are fastened to the roof adjacent each PV junction, (2) an elongated tray, and (3) an elongated cap or cover piece. In the preferred embodiment, the first piece of the system includes a plurality of base supports fastened to the roof adjacent each PV panel or panel pair. The plurality of base supports are fastened so as to be aligned with each other. The base supports include an opening to receive the wires that are connected to the PV panel.
- The second piece of the wire management system is an elongated tray, preferably a single elongated tray that overlies the plurality of base supports and is fitted into each of the base supports and supported and retained thereby. Holes or openings are preferably cut on site adjacent to where the wires are pulled into the base supports. The cut holes or openings receive the wires from the base supports.
- The third piece of the system is the cap or cover piece which covers the tray and locks onto the base support(s) to ensure a stable wire management system. Preferably the cover piece is substantially the same overall length as the tray and sufficiently long enough to overly the plural base supports. The locking of the cover piece to the base supports results in the tray being protected and “sandwiched” between the base supports and cover piece.
- Thus, it is an object of the present invention to provide a wire management system for a roof-mounted PV panel array that protects the wires and keeps the roof neat, clean, and free of loose wires.
- It is further an object of the present invention to provide a wire management system that protects the loose wires originating from the PV panels without penetrating the roof.
- It is further an object of the present invention to provide a wire management system that can be easily and effectively installed on the roof without penetrating the roof or requiring complex attachment components.
- These together with other objects and advantages which will become subsequently apparent reside in the details of construction and operation as more fully hereinafter described and claimed, reference being had to the accompanying drawings forming a part hereof, wherein like numerals refer to like parts throughout.

- Although only certain embodiments of the invention are explained in detail, it is to be understood that the invention is not limited in its scope to the details of construction and arrangement of components set forth in the following description or illustrated in the drawings. The invention is capable of other embodiments and of being practiced or carried out in various ways. Also, in describing the various embodiments, specific terminology will be resorted to for the sake of clarity. It is to be understood that each specific term includes all technical equivalents which operate in a similar manner to accomplish a similar purpose.
- As shown in
FIG. 1 , thewire management system 1 of the present invention comprises at least three components, abase support 100, anelongated tray 200, and a cap orcover piece 300. Each of these components is formed of a plastic material, preferably polyvinyl chloride (“PVC”) or acrylonitrile styrene acrylate (“ASA”) each of which are preferably outdoor rated. In addition, each of the plastic components includes an ultraviolet (“UV”) coating to provide protection from the ultraviolet rays. The coating can be a dual extruded Duracap brand UV coating. - As shown in
FIGS. 2-8 , thewire management system 1 is arranged to be positioned and secured to aroof 3 adjacent the solar panels or PV laminatedpanels 5. As shown inFIG. 2 , a pair of PV laminated panels are spaced apart just slightly greater than the width of theplanar base 101 of the base supports 100. As shown inFIGS. 2-8 , thebase supports 100 are formed in relatively short sections with eachbase support 100 positionable adjacent a PV laminated panel or panel pair and aligned with adjacent base supports. By contrast, theelongated tray 200 andcover piece 300 are preferably single piece components where each single component fits within the plurality of base supports 100 in a manner to be described. Of course, there could be circumstances where a single elongated base support is utilized. And thetray 200 and/orcover piece 300 could be formed of separate shorter segments that may abut each other or indeed may be slightly spaced apart in the lengthwise direction. - The
base support 100 is the first piece of thewire management system 1 to be installed, supports the entire system, and allows water to flow under thetray 200 and cover piece orcap 300 when the latter two elements are coupled to thebase support 100. Eachbase support 100 receiveswires 7 that are potted to thePV panels 5. Thebase support 100 includes aplanar base 101 that is mountable upon theroof 3 and is integrally connected with a pair ofvertical side panels 103 extending substantially perpendicularly and upwardly therefrom. Eachside panel 103 includes an internally facingside panel face 105 and an externally facingside panel face 107. Eachside panel 103 has anopening 109 to receive thewires 7 from thePV panel 5. The internally facingside panel faces 107 include a ledge 111, preferably substantially L-shaped with theshort leg 113 of the ledge 111 extending in an upward direction from thelonger leg 115. The ledge 111 extends the entire length of thebase support 100 and lies above the holes oropenings 109 in theside panels 103. Theopenings 109 receive thewires 7. - At the upper or
free end 117 of eachvertical side panel 103 is an interlockingedge member 119 that extends outwardly from the externally facingside panel face 105. The interlockingedge member 119 is angled downwardly to form alip 121 for receiving acorresponding lip 303 from thecover piece 300 as will be described. Obviously, other forms of interlock are possible and are within the scope of the present invention. Further, the interlockingedge 119 need not be precisely at thefree end 117 of thevertical side panel 103, but may be displaced downwardly therefrom. - Extending outwardly and angularly downwardly from each of the externally facing side panel faces 105 is a
wing member 121 having a length substantially equal to the length of theplanar base 101 and extends downwardly to a location substantially aligned with theplanar base 101. Preferably, eachwing member 121 includes a perpendicular or vertical edge as shown 123. However, it should be understood that thewing 121 can be formed without any edge, but extends completely angularly downwardly so as to rest upon thePV panels 5. Eachwing member 121 is intended to overly and protect the wire junction that extends from thePV panel 5. Based upon the thickness of the PV panel, there may be a slight tension or upward reactive force from thewing member 121 on thepanel 5 which thus provides a secure and tight mating between thebase support 100 and thepanel 5. - As shown in
FIG. 3 , after the plural base supports 100 are arranged adjacent the PV laminatedpanels 5 in an aligned direction so as to receive thetray 200 and cover piece 30, eachbase support 100 is secured to the roof by adhering strips of roof membrane 11 to affix thebase support 100 to theroof 3. The roof membrane 11 preferably is heat welded to the membrane of the roof or, alternatively, may include an adhesive or glue to secure itself to thebase support 100 androof 3. It should be realized that other effective means of securing thebase support 100 to theroof 3 may be utilized. - As stated earlier, it is desirable to include no holes in the
roof 3 and, thus, a heat welding of roofing membrane to roofing membrane is preferred. A strip of roofing membrane 11 may be laid acrossplanar base 101 and then heat welded to the roofing membrane below. Another alternative is a taping or gluing arrangement. However, there may be circumstances where the base support is secured to the roof in a manner that would require a hole, such as a screw hole or nail hole. Obviously, if thebase support 100 is secured by heat welding, taping or gluing, the area upon which the base supports will be adhered may require cleaning with a cleaning solvent so as to maintain a secured connection. - An
elongated tray 200 fits between the upright base support side panels 130 and is supported by the ledges 111 extending inwardly from the side panels. Theelongated tray 200 is sized so as to overly the plural base supports. It has been found that a tray having a 20 foot length may be effectively utilized with plural base supports numbering between 10 and 20, preferably 15, depending upon the number of photovoltaic devices protected. Each photovoltaic panel or panel pair should have a single base support adjacent thereto. Generally the spacing between adjacent base supports is greater than the length of the base supports. As previously discussed, there may be circumstances where the length of thetray 200 and coverpiece 300 are each shorter and may be installed in components, rather than one long piece for each element. - Turning to the configuration of the
tray 200, the tray includes aplanar tray base 201 having uprighttray side panels 203 extending vertically from thetray base 201 and having a pair ofvertical support legs 205 extending downwardly from thetray base 201. The support legs are supportable by the ledges 111 of the base supports 100 to maintain thetray 200 supportable by the base supports 100 between the basesupport side panels 103 and above the base support holes oropenings 109. - The
tray 200 is intended to be supplied to the installer with theplanar tray base 201 being free of holes or openings. As will be described, the holes/openings 207 are formed on site adjacent the location where each of the wires or wire sets 7 enter the base supports 100. Because the base supports 100 may not be precisely evenly spaced in the longitudinal direction, it cannot be determined in advance where theholes 207 in thetray 200 should be located. On the other hand, there may be circumstances where a single elongated base support is utilized in which case the openings within the tray may be pre-drilled. Both of these possibilities are within the scope of the present invention. - The
openings 207 to be cut in thebottom 201 of thetray 200 are substantially aligned with theopenings 109 of the base supports 100 so that thewires 7 from thePV panels 5, after being threaded through theopenings 109 of the base supports 100, may be threaded upwardly and outwardly within thetray 200. - The elongated cap or cover
piece 300 for covering thetray 200 and interlocking with the base supports 100 will now be described. Theelongated cover piece 300 is preferably of the same length as thetray 200 and is formed in a single section (or plural sections fit adjacent to each other) to provide a complete cover for the base supports 100 andtray 200. Thecover piece 300 includes a top portion 305 generally planar, although other shapes are certainly within the scope of the present invention. For example, the top portion 305 could be cylindrical, i.e., semi-circular in cross-section. Extending downwardly from the top portion 305 are a pair ofvertical side walls 307. Each of thevertical side walls 307 has afree edge 309 that defines an interlocking lip for interlocking with the interlockingedge member 119 of the plural base supports 100. This secures thecover piece 300 to the plural base supports 100 with thetray 200 supported therebetween. The cap or coverpiece 300 is the final piece of the wire management system that ties the system together and protects the wires from the elements. It is thetray 200 that carries all of the wires and connectors for the PV system protected by thecover piece 300. The space between the bottom 201 of thetray 200 and the plural base supports 100 provides a conduit for water to flow under thetray 200 andcap 300. - Installation of the system will now be described. As shown in
FIG. 2 , thePV laminate panels 5 are installed on theroof 3 aligned with adjacent panels and spaced apart a distance sufficient to enable the base supports 100 to be fitted therebetween. By way of example, if thebase support 100 is approximately three inches wide, it is suggested that the PV panels be spaced apart approximately four and one-half inches. After thePV laminate panels 5 are installed on the roof in a generally aligned position, each of the plural base supports 100 is placed on theroof 3 at a location where theholes 109 will be adjacent, or as close as possible, to where thewires 7, potted to thepanels 5, are located. Generally, the base supports 100 will be spaced an equal distance from each other, but this is not required. The positioning of the base supports 100 depends upon the positioning of thelaminate panels 5 and must be adjacent to thepanels 5 such that thewires 7 from the panels can be threaded through theopenings 109 of the base supports 100. As earlier stated, theroof 3 is first generally cleaned with a solvent so that the base supports 100 can be heat welded, taped or glued to the roof by the roof membrane 11 in a secure manner. This is shown inFIG. 3 where strips of roof membrane 11 are heat welded to secure the base supports to the roof. - After the base supports 100 are secured to the roof (
FIG. 3 ), thewires 7 from the PV panels are threaded through theopenings 109 of the base supports as shown inFIG. 4 . Then, as shown inFIG. 5 , theelongated tray 200 is generally positioned to overly the base supports and the wire locations are marked on thebottom 201 of thetray 200 so that ahole 207, such as a one inch hole, is drilled or cut out in thetray bottom 201 to allow the group ofwires 7 to pass therethrough. SeeFIG. 6 . (Only onehole 207 is depicted, but the location of the other holes, as marked by the installer on site, is shown and will be the location of the other holes.) - After the
holes 207 in the tray are cut out at the appropriate location, thetray 200 is positioned to be supported by the base supports 100 and thewires 7 that had been threaded internally within the base supports are threaded upwardly through theholes 207 of theplanar base 201. Thewires 7 that are shown inFIG. 7 as loosely supported by thetray 200 are ultimately connected to further components of the electrical system that receive the power generated by the PV panels. - The next step in the method is the securing of the cover piece or cap 300 to overly the
tray 200 and protect thewires 7, as well as to secure thecover piece 300 to the base supports 100 to provide a firm interlock. This is shown inFIG. 8 . The width between thevertical side walls 307 of thecover piece 300 is substantially the same width as the width between theside panels 103 of the base supports 100 so that, as thecover piece 300 is pressed downwardly from above, after thetray 200 is supported by the base supports 100, thewalls 307 of thecover piece 300 andside panel walls 103 of the base supports 100 will flex sufficiently to provide a snap interlock connection therebetween. - The foregoing is considered as illustrative only of the principles of the invention. Further, since numerous modifications and changes will readily occur to those skilled in the art, it is not desired to limit the invention to the exact construction and operation shown and described, and, accordingly, all suitable modifications and equivalents may be resorted to, falling within the scope of the invention.
