PV Array Mounting for Trapezoidal Metal and Low-Slope Roofs

Abstract

Components mount an array of solar panels to trapezoidal metal roofs or flat or low-slope roofs. Couplings may secure a trapezoidal metal roof mounting adapter to the peak of the trapezoidal portion of a trapezoidal metal roof, and couplings may secure additional mounting hardware to the adapter. Solar panels may connect to the rear portion of one support and the front portion of another support to achieve an angled installation to improve sun exposure. Wind diffusers may connect to solar panels to form a barrier extending from the upper-most edge of the installed solar panel downward toward the roof to impede wind. The flat and low-slope roof solution may comprise a penetration-free mechanism to install solar panels at an angle on a flat or substantially flat surface while impeding effect from wind and maintaining an electrically grounded connection between all components.

Description

BACKGROUND

Ever-increasing demands for energy and the ever-growing acknowledgement of the environmental damage caused by conventional fossil fuels have created an unprecedented demand for electricity generated by arrays of photovoltaic modules, or solar panels. A solar panel array necessitates infrastructure to secure the array to its site, orient the array, facilitate management and maintenance of the array, and establish a reliable electrical ground between the components of the array. Prior infrastructure technology exhibits significant shortcomings.

Commonly, photovoltaic modules are arranged on the sloped roof of a structure by securing a series of beams, or “rails” to the surface of the roof and clipping, clamping, screwing, or otherwise coupling the solar panels to the rails. This approach introduces cost and safety shortcomings. First, the rails are secured to the roof by puncturing the roof with a coupling, such as a screw or bolt. Such a perforation creates a risk of water entry at the points where the solar panel array is secured to the roof. Second, the rails themselves create a significant expense of time and material. The rails add to cost of material, manufacture, and shipping above and beyond the cost of the solar panels. The rails also increase the time installation crews must spend installing the solar array, creating additional man hours that further increase the cost of the system. Third, the rail-based system lacks a sophisticated method to provide an electrically grounded connection between the rails, solar panels, and other components to avoid creating an electrocution hazard. Lastly, the common installation method neglects other forms of roofs or other structures on which a solar panel array may be mounted. These shortcomings create an undeniable need for a solution that is more flexible, less labor intensive, and less material intensive.

Part 100 is an embodiment of a trapezoidal metal roof adapter featuring a substantially rigid structure with one or more apertures and one or more raised portions as well as a substantially water-impermeable lower membrane where the adapter may structurally support an additional photovoltaic array-mounting component. One or more of the apertures of the adapter 200 is sized and located to receive a screw. One or more aperture of the adapter 100 is sized and located to receive a bolt, machine screw, or similar coupling. The substantially rigid structure of the adapter 100 serves as a mounting portion for a mounting foot of a photovoltaic array.

FIG. 2 is an oblique view of the assembled components of FIG. 1, shown mounted to a roof panel or other support structure, such as trapezoidal roof panel 200. Operationally, installation occurs by placing the bottom membrane of the adapter (100) onto the peak of a trapezoid of a trapezoidal metal roof (200) and applying a screw through an aperture of the adapter into the roof, then applying a machine screw through an aperture of a mounting component (102) and into an aperture of the adapter (100) so that the adapter (100) structurally supports the mounting component (102).

FIG. 3 is an oblique view of an array of PV modules 300 mounted to support structures, such as corner supports 301. Corner supports 301 hold PV modules 300 at an angle relative to the surface on which the corner supports are resting, for example, such that the PV module surface is favorably inclined toward the sun, or the path of the sun. Corner supports 301 are shown as (optionally) mechanically attached and electrically ground-bonded to PV modules 300 as by a clip, bracket, fastener, or the like, such as a lever clip 302, as shown in FIG. 4, and previously described in prior filed patents and patent applications by the instant inventors. Further shown on each PV module 300 (but may be on one or more, but not all) is a panel, wall, deflector, or the like, such as wind diffuser 303, which is also shown as (optionally) attached to PV module 300 as by lever clip 302. FIGS. 3 and 4 are embodiments of a photovoltaic array consisting of (i) a frame member enclosing a photovoltaic laminate 300 where at least one side wall of the frame member has at least one female receiving portion integrated into its outside surface, (ii) a first support structure 301 with an upper and lower portion, (iii) a second support structure 301 with an upper and lower portion, (iv) a coupling 302 comprising a catch, an arm, a tooth, and a flange, and (v) a wind diffuser 303 with an aperture, where the coupling 302 connects the frame member to the supports 301 and the wind diffuser 303 such that all are electrically grounded and the supports structurally support the frame member and photovoltaic laminate.

The trapezoidal metal roof puck and flat- or low-sloped roof solution provide elegantly simple means to efficiently, quickly, and inexpensively install solar panel arrays on commonly-used forms of roofing or applicable surfaces. As discussed in greater detail below, the puck provides an interface between a trapezoidal roof and a rail-free mounting system that maintains a grounded connection and reduces material and labor costs, and the flat-roof solution provides a simple, effective, and safe structure and method for installing solar panel arrays on flat or substantially flat roofs.

As shown and described in FIGS. 1-2, puck adapter 100 for trapezoidal metal roofs may be secured to a surface, such as the peak of a trapezoid of a trapezoidal metal roof, using couplings such as screws 101. A leveling foot 102 may be secured to puck adapter 100 using a bolt or other coupling, as shown in FIG. 1. Puck 100, screws 101, and leveling foot 102 may be aluminum or another alloy, metal, or conductive material, and the contact between them maintains an electrically grounded connection. Once leveling foot 102 connects to puck 100, a rail-free solar panel array may be mounted to the trapezoidal metal roof as discussed in greater detail in a separate application by the instant inventor.

Referring now to FIGS. 6A and 6B, a puck is shown. A puck such as puck 600 may include a membrane 603, a base 608 with one or more coupling apertures 605A-605C, one or more supports such as supports 604A-604C, a block 607 with a leveling-foot aperture 606. Connecting a leveling foot to leveling-foot aperture 606 using a bolt or other coupling may permit the leveling foot to pivot. Depending on how the leveling foot pivots, it may rest on one or more supports 604A-604C which may prevent the leveling foot from bowing and placing undue torque on the bolt securing the leveling foot to puck 600. Screws or other couplings may secure puck 600 to a roof through coupling apertures 605A-605C. So securing puck 600 to a roof or other surface may compress membrane 603, providing increased water resistance to prevent atmospheric moisture from entering the perforation in the roof or other surface created by the screw or other coupling.

Referring now to FIGS. 3-5, a solar panel array is shown assembled with components that avoid penetrating the surface on which they are mounted and form an electrically grounded connection between all components. The array consists of supports 301 that secure and orient solar panels 300, wind diffusers 303, and lever clips 302 that secure the components of the array to one another.

Referring now to FIGS. 7A and 7B, a support such as support 301 is shown. Support 301 may include a rear foot 304, a rear leg 305, a rear plateau 306 with lever apertures 320A-320C, a slope 307, a front plateau 308 with lever apertures 320D-320F, a front leg 309, a front foot 310, and stoppers 311A-311H. Support 301 may be formed of aluminum, another alloy or metal, or another electrically conductive material. As shown and described in FIG. 3, supports 301 may be aligned in rows such that one support 301 supports the adjacent corners of two adjacent solar panels 300. A portion of the lower surface of the frame of the solar module 300 may rest on the lower plateau 306 or upper plateau 308 and may abut stoppers 311A-311H. Solar panels 300 may then be secured to supports 301 using lever clips 302.

Referring now to FIG. 8, a lever clip such as lever clip 302 is shown. Lever clip 302 may include a catch 331, an arm 332, a tooth 333, a notch 334, a head 335, and a flange 336 that form a cutout 337. Flange 336 may be placed into a lever aperture 320A-320F while tooth 33 may be placed into the groove of the frame of a solar panel 300 (discussed in detail in other applications by the instant inventor). Lever 332 may then be angled downward such that catch 331 is placed in the groove of the frame of solar panel 300. Tooth 333 may “bite” through any anodized surface that may exist on the frame of solar panel 300 such that conductive surfaces contact conductive surfaces of all components, creating an electrically grounded connection between the components. Wind diffuser 303 may connect to solar panel 300 using lever clamp 302 in a similar fashion.

Ballast blocks 905 may rest atop feet 906 to secure feet 906 to the relevant surface. An interlock 913 may connect to the groove of one PV module 901 and to the groove of an adjacent PV module 901. Lower support 911 may engage a rockit 909 of a rear leg 908 and angle downward to the foot 906 of the next PV module in a row.
