DETAILED DESCRIPTION

[0092] FIG. 1 presents a portion of a building surface 100. The building surface 100 may be of any appropriate type (e.g., a siding or roofing surface of a building) and may be defined in any appropriate manner (e.g., by a plurality of interconnected metal panels). In the illustrated embodiment, the building surface 100 is in the form of a roofing surface 100. In this regard, the roofing surface 100 has a pitch P (a slope or incline, the direction or orientation of which is indicated by the double-headed arrow in FIG. 1). As used herein, the arrow A identifies the direction of increasing slope (e.g., the uphill direction, the direction of increasing elevation along the roofing surface 100, or the up-slope direction). Conversely, the arrow B identifies the direction of decreasing slope (e.g., the downhill direction, the direction of decreasing elevation along the roofing surface 100, or the down-slope direction).

[0093] A plurality of photovoltaic modules 120 are positioned on the roofing surface 100 presented in FIG. 1. Each photovoltaic module 120 may be of any appropriate shape. In the illustrated embodiment, each photovoltaic module 120 is rectangular and is installed in a landscape orientation (with the long dimension of each photovoltaic module 120 being disposed transversely to the pitch P of the roofing surface 100). However, the photovoltaic modules 120 could be installed in a portrait orientation on the roofing surface 100. Typically the photovoltaic modules 120 will be installed in a plurality of rows and columns on the roofing surface 100.

[0094] Each photovoltaic module 120 may be characterized as including a first perimeter section 124 (e.g., an upper edge or end of the photovoltaic module 120 when installed on the roofing surface 100), an oppositely disposed second perimeter section 130 (e.g., a lower edge or end of the photovoltaic module 120 when installed on the roofing surface 100), a third perimeter section 136 (e.g., a left edge or end of the photovoltaic module 120 when installed on the roofing surface 100), and an oppositely disposed fourth perimeter section 138 (e.g., a right edge or end of the photovoltaic module 120 when installed on the roofing surface 100). As will be addressed in more detail below, a frame may extend about the entire perimeter of each photovoltaic module 120.

[0095] One embodiment of a photovoltaic assembly 150 that is installed on a building surface 100 is presented in FIGS. 2A-L. In this case, the building surface 100 is in the form of a roofing surface 100 having a pitch P, where again the arrow A identifies the up-slope direction and where the arrow B identifies the down-slope direction. The roofing surface 100 presented in FIGS. 2A-L is defined by a plurality of panels 102 that are appropriately interconnected (e.g., one edge or edge portion of one panel 102 may be disposed in overlapping/nesting relation with an adjacent panel 102 in the same row). Each panel 102 includes at least one rib 104, and may include one or more other structures such as one or more minor ribs 112 or the like. The ribs 104 of each panel 102 are disposed in at least substantially parallel relation and extend in the direction of the pitch P of the roofing surface 100 (e.g., the length dimension of each rib 104 may be disposed at the same pitch as the pitch P of the overall roofing surface 100).

[0096] The ribs 104 of the panels 102 that collectively define the roofing surface 100 may be of any appropriate configuration. In the illustrated embodiment, the ribs 104 are commonly referred to in the art as trapezoidal ribs 104. Other configurations may be appropriate. In any case, each rib 104 may be characterized as having an end section 106 (e.g., a flat surface; an uppermost portion of the rib 104 when defining the roofing surface 100). Two sidewalls 108 extend downwardly from the opposite sides of the end section 106 for each rib 104 (e.g., the two sidewalls 108 may be characterized as being spaced in a lateral dimension that is orthogonal to the pitch dimension, where the lateral and pitch dimensions are disposed within a common plane). The end section 106 and its two sidewalls 108 collectively define a hollow interior 110 for the corresponding rib 104. An interior angle (e.g., measured within the hollow interior 110 of a given rib 104) between the end section 106 and each of the sidewalls 108 is greater than 90 (an obtuse angle) for the configuration of the ribs 104 presented in FIGS. 2A-L.

[0097] The portion of the photovoltaic assembly 150 presented in FIGS. 2A-L includes a module bracket 200 and a corresponding pair of photovoltaic modules 120. It should be appreciated that the photovoltaic assembly 150 may include any appropriate number of photovoltaic modules 120 and any appropriate number of module brackets 200. Each module bracket 200 may include any appropriate number of wiring clips 236 (e.g., for supporting one or more wires used by the photovoltaic assembly 150). Each module bracket 200 may also be formed from any appropriate material or combination of materials (e.g., a metal or a metal alloy, and including from an electrically conductive material).

[0098] A given module bracket 200 of the photovoltaic assembly 150 may engage a single photovoltaic module 120, or a given module bracket 200 could simultaneously engage two different photovoltaic modules 120 (e.g., adjacently disposed modules 120). In this regard, the module bracket 200 includes a first mounting clip 202 (for engaging one photovoltaic module 120) and a separate second mounting clip 204 (for engaging a different photovoltaic module 120). The first mounting clip 202 and the second mounting clip 204 of a given module bracket 200 are spaced along the rib 104 on which the module bracket 200 is mounted (e.g., the first mounting clip 202 and the second mounting clip 204 are spaced along the pitch P of the roofing surface 100, with the first mounting clip 202 being disposed up-slope of its corresponding second mounting clip 204).

[0099] Each of the mounting clips 202, 204 may be characterized as including a first section 206 and a second section 208 that is disposed above or in overlying relation to its corresponding first section 206. One end of each of the mounting clips 202, 204 is open and may be characterized as an inlet 212 to the corresponding mounting clip 202, 204. An opposite end of each of the mounting clips 202, 204 is closed and may be characterized as an end section 210. Each mounting clip 202, 204 may be characterized as being at least generally U-shaped or of a money clip configuration.

[0100] The second section 208 of each mounting clip 202, 204 may be in contact with its corresponding first section 206 prior to receiving a portion of a photovoltaic module 120 being installed on the corresponding mounting clip 202, 204. In any case, the spacing between the first section 206 of each mounting clip 202, 204 and its corresponding second section 208 increases when a corresponding portion of a photovoltaic module 120 is installed on the corresponding mounting clip 202, 204. This expansion of the mounting clips 202, 204 may be realized by a flexing or bending (e.g., an elastic deformation) of the corresponding mounting clip 202, 204, may be characterized as a deflection of the second section 208 at least generally away from its corresponding first section 206, or both. For instance, the end section 210 of each mounting clip 202, 204 may be characterized as a living hinge that allows relative movement between its corresponding first section 206 and second section 208. In one embodiment, the end section 210 of each mounting clip 202, 204 may be characterized as being an arcuately-shaped, pliable section that is located between its corresponding first section 206 and second section 208, and that allows for a desired relative movement between its corresponding first section 206 and corresponding second section 208 (e.g., that allows the second section 208 of a given mounting clip 202, 204 to at least generally pivot away from and back toward its corresponding first section 206).

[0101] At least part of the second section 208 of each mounting clip 202, 204 may at least at some point in time be biased toward its corresponding first section 206. This biasing force may be provided by the end section 210 of the corresponding mounting clip 202, 204 (e.g., an elastic configuration). During at least a portion of the movement of the second section 208 away from its corresponding first section 208, the amount of the biasing force may progressively increase (e.g., by an elastic flexing of the corresponding end section 210). Although a biasing force could be exerted on the second section 208 when engaged with its corresponding first section 206, such is not required.

[0102] Each mounting clip 202, 204 of each module bracket 200 may mechanically engage and support a photovoltaic module 120 on the roofing surface 100. The mounting clips 202, 204 may also be used to establish an electrical connection with a corresponding photovoltaic module 120. In this regard, the surface of the second section 208 that faces or projects toward its corresponding first section 206 may include one or more projections 218 (e.g., having one or more sharp edges; an electrical contact). When a photovoltaic module 120 is installed in a given mounting clip 202, 204, the module 120 may be characterized as being bonded or electrically bonded to the corresponding mounting clip 202, 204 (or more generally as being bonded to the module bracket 200) via these projections 218. As two photovoltaic modules 120 may be installed on a given module bracket 200, an electrical path between these two modules 120 may be provided by such a module bracket 200. A string or collection of photovoltaic modules 120 may therefore be electrically connected (e.g., disposed at a common electrical potential) via the associated module brackets 200 (e.g., an electrical path may include the frames of the various photovoltaic modules 120 in the string, along with the corresponding module brackets 200 that engage these frames). This electrical path may be used to ground the string or collection of photovoltaic modules 120 (e.g., by running a single grounding wire from the frame of one of the photovoltaic modules 120 in the string to ground, as each adjacent pair of modules 120 in the string may be electrically interconnected by a shared module bracket 200).

[0103] One of the electrical contacts or projections 218 is illustrated in FIGS. 2I and 2J. As each electrical contact 218 is preferably of the same configuration, only one will be described. The electrical contact 218 cantilevers from a remainder of the second section 208 of the corresponding mounting clip 202, 204 (e.g., each electrical contact 218 may be punched from the second section 208). That is, the electrical contact 218 is partially separated from its corresponding second section 208 to define an aperture 218a in the second section 208. The boundary between the electrical contact 218 and the remainder of the second section 208 (where the electrical contact 218 remains attached to its corresponding second section 208) is identified by reference numeral 218b in FIG. 2J. The electrical contact 218 may flex or bend relative to its corresponding second section 208 at least generally about this boundary 218b, and as such this may also be referred to as hinge 218b.

[0104] In the illustrated embodiment, the electrical contact 218 is at least generally triangularly-shaped, and in any case extends downwardly toward its corresponding first section 206 at an angle. Other configurations may be appropriate. A free end section or point 218c of the electrical contact 218 may be characterized as being disposed in the direction of the closed end section 210 of the corresponding mounting clip 202, 204, while the hinge 218b may be characterized as being disposed in the direction of the inlet 212 to the corresponding mounting clip 202, 204. That is, the electrical contact 218 may be characterized as extending from its hinge 218b with the second section 208, at least generally in the direction of the closed end section 210 of the corresponding mounting clip 202, 204. The electrical contact 218 may also be characterized as extending from its hinge 218b with the second section 208, at least generally in the direction of its corresponding first section 206.

[0105] As noted, the first mounting clip 202 and the second mounting clip 204 are spaced along the pitch P of the roofing surface 100, with the first mounting clip 202 being disposed up-slope of its corresponding second mounting clip 204 (in the up-slope direction A). The mounting clips 202, 204 are oriented such that the inlet 212 of the first mounting clip 202 at least generally projects toward or faces in the direction of the second mounting clip 204, and such that the inlet 212 of the second mounting clip 204 at least generally projects toward or faces in the direction of the first mounting clip 202 (e.g., the inlet 212 to the first mounting clip 202 may project in the down-slope direction B; the inlet 212 to the second mounting clip 204 may project in the up-slope direction A). Stated another way, the mounting clips 202, 204 are oriented such that the end section 210 of the first mounting clip 202 is disposed up-slope of the inlet 212 of the first mounting clip 202, and such that the end section 210 of the second mounting clip 204 is disposed down-slope of the inlet 212 of the second mounting clip 204. Stated yet another way, the mounting clips 202, 204 are oriented such that the inlet 212 of the second mounting clip 204 is disposed up-slope of the end section 210 of the second mounting clip 204, such that the inlet 212 of the first mounting clip 202 is disposed up-slope of the inlet 212 of the second mounting clip 204, and such that the end section 210 of the first mounting clip 202 is disposed up-slope of the inlet 212 of the first mounting clip 202.

[0106] A base section 220 of the module bracket 200 is disposed between the first mounting clip 202 and the second mounting clip 204 along the pitch P of the roofing surface 100 when the module bracket 200 is installed thereon. The base section 220 may be characterized as being an at least generally flat or planar structure. The mounting clips 202, 204 of the module bracket 200 are offset from the base section 220. In this regard, one riser section 214 extends from base section 220 (e.g., one end thereof) to the first mounting clip 202. Another riser section 214 extends from the base section 220 (e.g., an opposite end thereof) to the second mounting clip 204. The riser sections 214 may be at least generally parallel to one another, and may be oriented at least generally perpendicularly to the base section 220. At least one wiring clip 236 may be disposed on the underside of the first mounting clip 202 (e.g., disposed within the space between the first mounting clip 202 and the rib 104 (e.g., its end section 106) on which the module bracket 200 is mounted). Similarly, at least one wiring clip 236 may be disposed on the underside of the second mounting clip 204 (e.g., disposed within the space between the second mounting clip 204 and the rib 104 (e.g., its end section 106) on which the module bracket 200 is mounted).

[0107] In the illustrated embodiment, the two riser sections 214 of the module bracket 200 are of a common height or length. As such, the first mounting clip 202 and the second mounting clip 204 of the module bracket 200 are disposed at a common elevation relative to the base section 220. When the module racket 200 is installed on the building surface 100, the first mounting clip 202 and the second mounting clip 204 may be characterized as being at least generally coplanar with each other in a dimension that is parallel with the pitch P of the roofing surface 100. Moreover, the first mounting clip 202 and the second mounting clip 204 may be characterized as being disposed at a common, higher elevation than the base section 220, measured relative to a reference plane that contains the flat, base sections of the panel 102 (and from which the ribs 104 may extend).

[0108] The base section 220 of the module bracket 200 may be seated on the end section 106 of one of the ribs 104 of the roofing surface 100. The surface of the base section 220 that that interfaces with or at least projects toward an end section 106, when the module bracket 200 is installed on the corresponding rib 104, may include a pair of stiffening beads or stiffeners 226. These stiffeners 226 may enhance the structural integrity of the module bracket 200, and may also extend along the riser sections 214 and the first sections 206 of the mounting clips 202, 204. The convex or protruding configuration/shape of the stiffeners 226 on the lower surface of the base section 220 may also function to reduce the potential for over-compressing a gasket 216 that may be positioned between the base section 220 and the end section 106 of the rib 104 on which the module bracket 200 is being installed.

[0109] One or more panel fasteners 238 may be used to secure the module bracket 200 to a rib 104 of the roofing surface 100. In the illustrated embodiment, two panel fasteners 238 (e.g., threaded screws) extend through the base section 220 of the module bracket 200, through the end section 106 of the rib 104, and terminate within the hollow interior 110 of the rib 104. Any appropriate number of panel fasteners 238 may be used, and each may be of any appropriate type. The base section 220 of the module bracket 200 may include one or more fastener apertures 228, each of which may accommodate a single panel fastener 238.

[0110] Each module bracket 200 accommodates a maximum of two photovoltaic modules 120. Portions of two photovoltaic modules are illustrated in FIGS. 2A and 2Lone of the modules 120 is further identified by reference numeral 120a, and the other is further identified by reference numeral 120b. Each photovoltaic module 120 may be characterized as having a photovoltaic cell or body 122. A first frame section 126 may define the first perimeter section 124 of the corresponding photovoltaic module 120. A second frame section 132 may define the second perimeter section 130 of the corresponding photovoltaic module 120. The third perimeter section 136 (FIG. 1) of a photovoltaic module 120 could be defined by a frame section of any appropriate configuration (e.g., to protect the corresponding edge of the PV body 122), as could the fourth perimeter section 138 (FIG. 1) of a photovoltaic module 120. In any case, the first frame section 126 of the photovoltaic module 120 (e.g., an uphill end or edge of the photovoltaic module 120 when installed on the roofing surface 100) may include a first module flange 128 that cantilevers or extends at least generally in the direction of the second frame section 132 of the photovoltaic module 120 (e.g., a downhill end or edge of the photovoltaic module 120 when installed on the roofing surface 100). Similarly, the second frame section 132 of the photovoltaic module 120 (e.g., a downhill end or edge of the photovoltaic module 120 when installed on the roofing surface 100) may include a second module flange 134 that cantilevers or extends at least generally in the direction of the first frame section 126 of the photovoltaic module 120 (e.g., an uphill end or edge of the photovoltaic module 120 when installed on the roofing surface 100). The first module flange 128 may be characterized as extending at least generally in the direction of the second module flange 134, and vice versa. The first module flange 128 may be characterized as extending in the down-slope direction B when the photovoltaic module 120 is installed on the roofing surface 100 (and terminates at free end 128a that is spaced from a free end 134a of the second module flange 134 for this same module 120). Similarly, the second module flange 134 may be characterized as extending in the up-slope direction A when the photovoltaic module 120 is installed on the roofing surface 100 (and terminates at a free end 134a that is spaced from a free end 128a of the first module flange 128 for this same module 120).

[0111] The module bracket 200 provides what may be characterized as a slide fit for each photovoltaic module 120 installed thereon. An embodiment of an installation method that utilizes this slide fit connection will be discussed in more detail below. Generally, the second module flange 134 of the photovoltaic module 120a may be slid relative to the first mounting clip 202. This will initially direct the free end 134a of the second module flange 134 of the photovoltaic module 120a into the inlet 212 of the first mounting clip 202. Further relative movement between the photovoltaic module 120a and the first mounting clip 202 may move its second section 208 at least generally away from its first section 206 (e.g., by a flexing of the end section 210 of the first mounting clip 202; by the second section 208 at least generally moving or pivoting away from its corresponding first section 206). Eventually, the free end 134a of the second module flange 134 may come into contact the end section 210 of the first mounting clip 202 to positionally register the photovoltaic module 120a relative to the module bracket 200. In any case and as discussed above, an electrical path may be provided between the module bracket 200 and the photovoltaic module 120a by the second module flange 134 of the module 120a being sandwiched between the second section 208 and the corresponding first section 206 of the first mounting clip 202, where the projections 218 on the second section 208 may facilitate the establishment of electrical contact with the second module flange 134 of the module 120a.

[0112] The photovoltaic module 120b may be installed on the second mounting clip 206 in the same general manner as the photovoltaic module 120a. Generally, the first module flange 128 of the photovoltaic module 120b may be slid relative to the second mounting clip 204. This will initially direct the free end 128a of the first module flange 128 of the photovoltaic module 120b into the inlet 212 of the second mounting clip 204. Further relative movement between the photovoltaic module 120b and the second mounting clip 204 will then move its second section 208 at least generally away from its first section 206 (e.g., by a flexing of the end section 210 of the second mounting clip 204; by the second section 208 at least generally moving or pivoting away from its corresponding first section 206). Eventually, the free end 128a of the first module flange 128 may come into contact the end section 210 of the second mounting clip 204 to positionally register the photovoltaic module 120b relative to the module bracket 200. In any case and as discussed above, an electrical path may be provided between the module bracket 200 and the photovoltaic module 120b by the first module flange 128 of the module 120b being sandwiched between the second section 208 and the corresponding first section 206 of the second mounting clip 204, where the projections 218 on the second section 208 may facilitate the establishment of electrical contact with the first module flange 128 of the module 120b.

[0113] A number of observations may be made with regard to the module bracket 200 in relation to installing photovoltaic modules on the roofing surface 100 (and that are equally applicable to the module brackets 200.sup.i, 200.sup.iii, 200.sup.v, and 200.sup.vi discussed below). One is that contact between the module bracket 200 and the photovoltaic modules 120a, 120b is limited to the mounting clips 202, 204no other portion of the module bracket 200 contacts either the photovoltaic module 120a or the photovoltaic module 120b. Another is that the entirety of the retention forces exerted by the module bracket 200 on the photovoltaic modules 120a, 120b is provided by the mounting clips 202, 204 (no other forces are used to retain the modules 120a, 120b on the module bracket 200). The mounting clip 202 may exert a compressive force on the second module flange 134 of the photovoltaic module 120a. Similarly, the mounting clip 204 may exert a compressive force on the first module flange 128 of the photovoltaic module 120b.

[0114] The riser sections 214 of the module bracket 200 provide a vertical offset between the base section 220 and each of the mounting clips 202, 204, as noted. This increases the spacing between the photovoltaic modules 120a, 120b and the underlying roofing surface 100. One advantage of this increased spacing between the photovoltaic modules 120a, 120b and the underlying roofing surface 100 is an enhanced cooling of the photovoltaic modules 120a, 120b, which may increase their operational efficiency (e.g., by accommodating an increased airflow between the roofing surface 100 and the underside of the photovoltaic modules 120a, 120b). Another advantage of this increased spacing between the photovoltaic modules 120a, 120b and the underlying roofing surface 100 is enhanced access to the underside of the photovoltaic modules 120a, 120b (e.g., for wire management; providing more room for installers/service technicians to install/access/move/remove wires on the underside of the photovoltaic modules 120a, 120b). The vertical offset between the base section 220 and each of the mounting clips 202, 204 is at least about 0.5 in one embodiment, and is at least about 0.75 in another embodiment (e.g., measured orthogonally to the pitch P of the roofing surface 100 when the module bracket 200 is installed on the roofing surface 100).

[0115] The module bracket 200 itself provides an electrical connection between the photovoltaic module 120a and the photovoltaic module 120bthe module bracket 200 provides an electrical path between the modules 120a and 120b. At least one electrical contact 218 is incorporated by each of the mounting clips 202, 204. In the illustrated embodiment, each electrical contact 218 is incorporated by the second section 208 on each of the mounting clips 202, 204. As the second module flange 134 of the photovoltaic module 120a is slid into the mounting clip 202, at least one (and preferably multiple) electrical contacts 218 should engage the second module flange 134. The free end section 218c of each such electrical contact 218 may scratch the surface of the second module flange 134 of the photovoltaic module 120a to enhance the electrical connectivity between the mounting clip 202 and the photovoltaic module 120a. Similarly, as the first module flange 128 of the photovoltaic module 120b is slid into the mounting clip 204, at least one (and preferably multiple) electrical contacts 218 should engage the first module flange 128. The free end section 218c of each such electrical contact 218 may scratch the surface of the first module flange 128 of the photovoltaic module 120b to enhance the electrical connectivity between the mounting clip 204 and the photovoltaic module 120b.

[0116] Based upon the described orientation of the electrical contacts 218 on each of the mounting clips 202, 204, sliding the module flanges 134, 128 into the mounting clips 202, 204, respectively, may cause one or more of the electrical contacts 218 to move relative to the remainder of its corresponding second section 208 (of the corresponding mounting clip 202, 204)the free end section 218c of one or more electrical contacts 218 may move at least generally away from the corresponding module flange 128, 134 (and at least generally about its corresponding hinge 218b). However, the free end section 218c of each electrical contact 218 should remain in contact with the corresponding module flange 128, 134. In one embodiment, contact between the second section 208 of each mounting clip 202, 204 and the corresponding module flange 128, 134 may be limited to one or more electrical contacts 218 (e.g., it may be that the only portion of a given second section 208 to contact a given module flange 128, 134 is one or more of its electrical contacts 218).

[0117] The described orientation of each electrical contact 218 may also provide resistance to sliding the photovoltaic modules 120a, 120b out of the mounting clips 202, 204, respectively. Sliding the photovoltaic module 120a relative to the mounting clip 202 in a direction to withdraw the second module flange 134 out through the inlet 212 of the mounting clip 202 may cause one or more electrical contacts 218 to move relative to the remainder of its corresponding second section 208 of the mounting clip 202the free end section 218c of one or more electrical contacts 218 may move at least generally toward the second module flange 134 of the photovoltaic module 120a (and at least generally about its corresponding hinge 218b in a direction that is opposite of the direction that such a free end section 218c may move during installation; a wedging action for one or more electrical contacts 218). Similarly, sliding the photovoltaic module 120b relative to the mounting clip 204 in a direction to withdraw the first module flange 128 out through the inlet 212 of the mounting clip 204 may cause one or more electrical contacts 218 to move relative to the remainder of its corresponding second section 208 of the mounting clip 204the free end section 218c of one or more electrical contacts 218 may move at least generally toward the first module flange 128 of the photovoltaic module 120b (and at least generally about its corresponding hinge 218b in a direction that is opposite of the direction that such a free end section 218c may move during installation; a wedging action for one or more electrical contacts 218).

[0118] FIG. 3 present another embodiment of a photovoltaic assembly 150.sup.i that utilizes a variation of the module bracket 200 discussed above in relation to FIGS. 2A-L. Those portions of the module bracket 200.sup.i of FIG. 3 that differ from the module bracket 200 of FIGS. 2A-L are identified by a superscripted i. Unless otherwise noted, the discussion presented above with regard to the module bracket 200 is applicable to the module bracket 200.sup.i.

[0119] The module bracket 200.sup.i of FIG. 3 attaches to the rib 104 of the roofing surface 100 in a different manner than the module bracket 200 of FIGS. 2A-L. The module bracket 200.sup.i utilizes a pair of bracket flanges 230 that extend from opposite sides of the base section 220.sup.i of the module bracket 200.sup.i. One of the bracket flanges 230 may be positioned alongside at least an upper portion of one of the sidewalls 108 of the rib 104 on which the module bracket 200.sup.i is being installed, while the other of the bracket flanges 230 may be positioned alongside at least an upper portion of the other of the sidewalls 108 of this same rib 104. A gasket 216.sup.i may be positioned between one of the bracket flanges 230 and its corresponding sidewall 108 of the rib 104, while another gasket 216.sup.i may be positioned between the other of the bracket flanges 230 and its corresponding sidewall 108 of the rib 104. Each bracket flange 230 may include one or more fastener apertures 232 (two in the illustrated embodiment). At least one panel fastener 238 (two in the illustrated embodiment) may be directed through one of the bracket flanges 230 (e.g., through a corresponding fastener aperture 232), through any corresponding gasket 216.sup.i, through a corresponding portion of the sidewall 108 of the rib 104, and may terminate within the hollow interior 110 of the rib 104. At least one panel fastener 238 (two in the illustrated embodiment) may be directed through the other of the bracket flanges 230 (e.g., through a corresponding fastener aperture 232), through any corresponding gasket 216.sup.i, through a corresponding portion of the sidewall 108 of the rib 104, and may terminate within the hollow interior 110 of the rib 104. As such, the base section 220.sup.i of the module bracket 200.sup.i need not include any fastener apertures 232 for the FIG. 3 embodiment. The base section 200.sup.i could also thereby incorporate one or more wiring clips 236.

[0120] The module bracket 200.sup.i could be fabricated in any appropriate manner. The mounting clips 202, 204, the riser sections 214, and the base section 220.sup.i could be of a one-piece construction (e.g., integrally formed from a piece of sheet metal). Each of the bracket flanges 230 could be separately formed and separately attached to the opposing sides of the base section 220.sup.i in any appropriate manner. Although not shown, the module bracket 200.sup.i could utilize the stiffeners 226 discussed above in relation to the module bracket 200.

[0121] FIGS. 4A-G present another embodiment of a photovoltaic assembly 150.sup.ii that utilizes a variation of the module bracket 200 discussed above in relation to FIGS. 2A-L. Those portions of the module bracket 200.sup.ii of FIGS. 4A-G that differ from the module bracket 200 of FIGS. 2A-L are identified by a superscripted ii. Unless otherwise noted, the discussion presented above with regard to the module bracket 200 is applicable to the module bracket 200.sup.ii.

[0122] The module bracket 200.sup.ii of FIGS. 4A-G eliminates the two riser sections 214 used by the module bracket 200 of FIGS. 2A-L. As such, the base section 220 of the module bracket 200.sup.ii is at least generally coplanar with the first section 206 of each of the mounting clips 202, 204. The gasket 216.sup.ii may be of an extended length so as to be disposed between the upper section 106 of the rib 104 and each of the first mounting clip 202, the base section 220, and the second mounting clip 204. In one variation of the module bracket 200.sup.ii (not shown), a pair of bracket flanges 230 could extend from the opposite sides of the base section 220, and could be used to attach the module bracket 200.sup.ii to the rib 104 of the roofing surface 100 in the manner of the FIG. 3 embodiment addressed above. In another variation of the module bracket 200.sup.ii (not shown), a pair of bracket flanges 230 could extend from the opposite sides of the base section 220, but the module bracket 200.sup.iii could still be attached to the rib 104 of the roofing surface 100 in the manner illustrated in FIGS. 4A-G (e.g., not using any panel fasteners 238 in conjunction with the bracket flanges 230).

[0123] A number of observations may be made with regard to the module bracket 200.sup.ii in relation to installing photovoltaic modules on the roofing surface 100. As the mounting clips 202, 204 are not offset from the base section 220 in the case of the module bracket 200.sup.ii, the module bracket 200.sup.ii does not provide the spacing that is provided by the embodiment of FIGS. 2A-L and the associated benefits. However, the entirety of the retention forces exerted by the module bracket 200.sup.ii on the photovoltaic modules 120a, 120b continues to be provided by the mounting clips 202, 204 (no other forces are used to retain the modules 120a, 120b on the module bracket 200.sup.ii). Moreover, the mounting clip 202 may exert a compressive force on the second module flange 134 of the photovoltaic module 120a. Similarly, the mounting clip 204 may exert a compressive force on the first module flange 128 of the photovoltaic module 120b. As the module bracket 200.sup.ii also includes at least one least one electrical contact 218 for each of the mounting clips 202, 204, the corresponding discussion presented above with regard to the embodiment of FIGS. 2A-L is equally applicable to the embodiment of FIGS. 4A-G.

[0124] FIG. 5 presents another embodiment of a photovoltaic assembly 150.sup.iii that utilizes a variation of the module bracket 200.sup.i discussed above in relation to FIG. 3. Those portions of the module bracket 200.sup.iii of FIG. 5 that differ from the module bracket 200.sup.i of FIG. 3 are identified by a superscripted iii. Unless otherwise noted, the discussion presented above with regard to the module brackets 200 and 200.sup.i is applicable to the module bracket 200.sup.iii.

[0125] The module bracket 200.sup.iii of FIG. 5 is configured to dispose the mounting clips 202, 204 at different elevations from the roofing surface 100 (e.g., the mounting clips 202, 204 are spaced a different distance from a reference plane that at least generally contains the end section 106 of the ribs 104 for the roofing surface 100). In this regard, the two riser sections 214a, 214b are of different lengths in the case of the module bracket 200.sup.iii (the riser sections 214a, 214b may continue to be at least generally parallel to one another, and may continue to be at least generally perpendicular to the base section 220.sup.i). In the illustrated embodiment, the riser section 214a that extends between the base section 220.sup.i and the first mounting clip 202 is shorter than the riser section 214b that extends between the base section 220.sup.i and the second mounting clip 204, although this could be reversed. That is and for the illustrated embodiment, the second mounting clip 204 is disposed at a higher elevation than the first mounting clip 202 (measured relative to a reference plane that contains the end sections 106 of the ribs 104 for the roofing surface 100). This may be used to dispose the photovoltaic modules 120a, 120b engaged by the module bracket 200.sup.iii at an angle relative to the roofing surface 100 (e.g., so the modules 120a, 120b are disposed in non-parallel relation to the roofing surface 100).

[0126] Whichever of the mounting clips 202, 204 is disposed at the lowest elevation in the case of the module bracket 200.sup.iii (measured orthogonally to the pitch P of the roofing surface 100), this mounting clip 202, 204 is still offset from the base section 220.sup.i by a distance of at least about 0.5 in one embodiment, and by a distance of at least about 0.75 in another embodiment. As such, each of the mounting clips 202, 204 may be offset from the base section 220.sup.i by a distance of at least about 0.5 in one embodiment, and by a distance of at least about 0.75 in another embodiment, to provide the enhanced spacing advantages discussed above with regard to the embodiment of FIGS. 2A-L.

[0127] Although not shown in FIG. 5, the module bracket 200.sup.iii could utilize the stiffeners 226 discussed above in relation to the module bracket 200. In one variation of the module bracket 200.sup.iii (not shown), the bracket flanges 230 could be eliminated and the module bracket 200.sup.iii could be attached to the rib 104 of the roofing surface 100 in the manner of the embodiment of FIGS. 2A-L. In another variation of the module bracket 200.sup.iii (not shown), the bracket flanges 230 could be retained, but the module bracket 200.sup.iii could be attached to the rib 104 of the roofing surface 100 in the manner of the embodiment of FIGS. 2A-L (e.g., not using any panel fasteners 238 in conjunction with the bracket flanges 230).

[0128] FIGS. 6A-L present another embodiment of a photovoltaic assembly 150.sup.iv that may utilize the same module bracket 200 discussed above in relation to FIGS. 2A-L, but a different manner of maintaining the module bracket 200 is a fixed position relative to the roofing surface 100. Generally, a separate panel bracket 240 is positioned over the module bracket 200 when positioned on a rib 104 of the roofing surface 100, and the panel bracket 240 is instead anchored to this rib 104. As such, the module bracket 200 in the embodiment of FIGS. 6A-L could eliminate the fastener apertures 228 that extend through the base section 220, as they are not utilized in this configuration. The panel bracket 240 could also be used with the module bracket 200.sup.ii discussed above in relation to FIGS. 4A-G, as well as with the module bracket 200.sup.vi that will be discussed below in relation the FIGS. 8A-G (but for installations on the roofing surface 100, versus the roofing surface 100 shown in FIGS. 8A-G).

[0129] The panel bracket 240 used by the photovoltaic assembly 150.sup.iv of FIGS. 6A-L includes a cap section 242 and a pair of bracket flanges 230.sup.iv at least generally of the type used in the FIG. 3 embodiment discussed above. As the bracket flanges 230.sup.iv do not extend from the base section 220, the bracket flanges 230.sup.iv in FIGS. 6A-L are further identified by a superscripted iv. A separate transition section 234 may interconnect the cap section 242 with the corresponding bracket flange 230.sup.iv. Each transition section 234 may be at least generally s-shaped.

[0130] The panel bracket 240 used by the photovoltaic assembly 150.sup.iv of FIGS. 6A-L may be fabricated in any appropriate manner. For instance, the panel bracket 240 could be of a one-piece construction (e.g., having the cap section 242 (which may include a wiring clip 236) and the two bracket flanges 230.sup.iv being integrally formed from a piece of sheet metal). Alternatively, each of the bracket flanges 230.sup.iv could be separately formed and separately attached to the opposing sides of the cap section 242 in any appropriate manner.

[0131] The module bracket 200 may be positioned on the upper section 106 of one of the ribs 104 for the roofing surface 100. The panel bracket 240 may then be positioned over the module bracket 200, such that the base section 220 of the module bracket 200 is disposed (e.g., sandwiched) between the cap section 242 of the panel bracket 240 and the end section 106 of one of the ribs 104. One of the bracket flanges 230.sup.iv will then be positioned alongside at least an upper portion of one of the sidewalls 108 of the rib 104, while the other of the bracket flanges 230.sup.iv will be positioned alongside at least an upper portion of the other of the sidewalls 108 of this same rib 104. Again, a gasket 216.sup.i may be positioned between one of the bracket flanges 230.sup.iv and its corresponding sidewall 108 of the rib 104, while another gasket 216.sup.i may be positioned between the other of the bracket flanges 230.sup.iv and its corresponding sidewall 108 of the rib 104.

[0132] Each bracket flange 230.sup.iv may include one or more fastener apertures 232 (two in the illustrated embodiment). At least one panel fastener 238 (two in the illustrated embodiment) may be directed through one of the bracket flanges 230.sup.iv (e.g., through a corresponding fastener aperture 232), through any corresponding gasket 216.sup.i, through a corresponding portion of the sidewall 108 of the rib 104, and may terminate within the hollow interior 110 of the rib 104. At least one panel fastener 238 (two in the illustrated embodiment) may be directed through the other of the bracket flanges 230.sup.iv (e.g., through a corresponding fastener aperture 232), through any corresponding gasket 216.sup.i, through a corresponding portion of the sidewall 108 of the rib 104, and may terminate within the hollow interior 110 of the rib 104. As such, the base section 220 of the module bracket 200 need not include any fastener apertures 232.

[0133] FIGS. 7A-G present another embodiment of a photovoltaic assembly 150.sup.v that may utilize a module bracket similar to that used by the embodiment of FIGS. 2A-L, but which has been adapted for use with another type of roofing surface. The roofing surface 100 associated with the photovoltaic assembly 150.sup.v is defined by a plurality of panels 102 that are appropriately interconnected (e.g., one edge or edge portion of one panel 102 may be nested or interlocked with an adjacent panel 102 in the same row). Each adjacent pair of panels 102 of the roofing surface 100 is interconnected in a manner so as to define a standing seam 114. A base may be disposed between the opposing edges of each panel 102. The entirety of this base may be flat or planar. However, one or more small structures may be formed/shaped into the base of one or more panels 102 of the building surface 100, for instance one or more crests, minor ribs, intermediate ribs, pencil ribs, striations, fluting, flutes, or the like.

[0134] The module brackets 200.sup.v used by the photovoltaic assembly 150.sup.v of FIGS. 7A-G are not directly attached to the roofing surface 100, in contrast to the embodiments of FIGS. 2A-6L. Instead, a mounting device 260 is attached to a standing seam 114 of the roofing surface 100, and the module bracket 200.sup.v is attached to this mounting device 260.

[0135] The mounting device 260 includes an upper surface 262, an oppositely disposed lower or bottom surface 266, a pair of oppositely disposed side surfaces 264, and a pair of oppositely disposed ends 268. A slot 270 extends between the two ends 268 of the mounting device 260. At least an upper portion of a standing seam 114 may be received in this slot 270. At least one threaded hole 278 extends from one of the side surfaces 264 to the slot 270. Multiple threaded holes 278 (that extend to the slot 270) could be provided on a given side surface 264. At least one threaded hole 278 could extend from one of the side surfaces 264 of the mounting device 260 to the slot 270, and at least one threaded hole 278 could extend from the other of the side surfaces 264 of this mounting device 260 to the slot 270. In any case, at least one seam fastener 245 may be threadably engaged with the mounting device 260 (e.g., via a corresponding threaded hole 278), and may extend into the slot 270 to engage a standing seam 114 disposed therein. The end of each seam fastener 245 that engages a standing seam 114 disposed in the slot 270 may be configured so as to not penetrate or puncture the roofing surface 100 (e.g., having a rounded or convexly-shaped end). As such, one or more seam fasteners 245 may be used to attach the mounting device 260 to the roofing surface 100 (more specifically, to attach the mounting device 260 to one of the standing seams 114 of the roofing surface 100).

[0136] The standing seam 114 of the building surface 100 is commonly referred to as a vertical standing seam configuration. The upper surface 262 of the mounting device 260 may include at least one flat section for interfacing with the module bracket 200.sup.v (more specifically, the base section 220.sup.v of the module bracket 200.sup.v). This upper surface 262 may also include a threaded hole 276 for interconnecting the module bracket 200.sup.v with the mounting device 260 when installed on the vertical standing seam 114. However, the mounting device 260 may also be used to install the module bracket 200.sup.v on what is commonly referred to as a horizontal standing seam configuration (e.g., where an end section of the standing seam may be disposed at least generally parallel with the pitch of the roofing surface). In this regard, at least one of the side surfaces 264 of the mounting device 260 may include at least one flat section and at least one threaded hole 276. In this instance, the base section 220.sup.v of the module bracket 220.sup.v would be disposed on such a side surface 264 of the mounting device 260.

[0137] With the base section 220.sup.v of the module bracket 200.sup.v being positioned on the upper surface 262 of the mounting device 260 (or on the noted side surface 264 in the case of a horizontal standing seam configuration), a threaded fastener 250 (e.g., a bolt) may be directed through an elongated slot 222 on the base section 220.sup.v of the module bracket 200.sup.v, and may be threaded onto the mounting device 260 via a threaded hole 276. Any appropriate aperture may extend through the base section 220.sup.v of the module bracket 200.sup.v. However, the elongated slot 222 in the illustrated embodiment provides for at least some level of adjustment of the relative position between the module bracket 200.sup.v and the mounting device 260 prior to disposing the threaded fastener 250 in a position that clamps the module bracket 200.sup.v onto the mounting device 260. In any case, the mounting clips 202, 204 will now be disposed in spaced relation to the roofing surface 100 (e.g., above or in overlying relation to the standing seam 114 to which the module bracket 200.sup.v is interconnected via a mounting device 260).

[0138] FIGS. 8A-G present another embodiment of a photovoltaic assembly 150.sup.vi. Generally, the photovoltaic assembly 150.sup.vi adapts the module bracket 200.sup.iii from the embodiment of FIG. 5 for use with the roofing surface 100 from the embodiment of FIGS. 7A-G. The base section 220.sup.vi of the module bracket 200.sup.vi includes an elongated aperture 222 of the type discussed above in relation to the embodiment of FIGS. 7A-G. However, since the module bracket 200.sup.vi presented in FIGS. 8A-G does not show a pair of stiffening beads or stiffeners 226, the superscripted vi notation is used for its base section 220.sup.vi (although stiffeners 226 could be used by the module bracket 200.sup.vi). Otherwise, the module bracket 200.sup.vi for the photovoltaic assembly 150.sup.vi may be installed on a standing seam 114 in accordance with the discussion of FIGS. 7A-G. Other than the manner of attachment, the discussion presented above with regarding to the embodiment of FIG. 5 is applicable to the embodiment of FIGS. 8A-G (and vice versa).

[0139] Whichever of the mounting clips 202, 204 is disposed at the lowest elevation in the case of the module bracket 200.sup.vi (measured orthogonally to the pitch P of the roofing surface 100), this mounting clip 202, 204 is still offset from the base section 220.sup.vi by a distance of at least about 0.5 in one embodiment, and by a distance of at least about 0.75 in one embodiment. As such, each of the mounting clips 202, 204 may be offset from the base section 220.sup.vi by a distance of at least about 0.5 in one embodiment, and by a distance of at least about 0.75 in another embodiment, to provide the enhanced spacing advantages discussed above with regard to the embodiment of FIGS. 2A-L.

[0140] FIGS. 9A-G present another embodiment of a photovoltaic assembly 150.sup.vii. Generally, the photovoltaic assembly 150.sup.vii adapts the module bracket 200.sup.ii from the embodiment of FIGS. 4A-G for use with the roofing surface 100 from the embodiment of FIGS. 7A-G. The base section 220.sup.vii of the module bracket 200.sup.vii includes an elongated aperture 222 of the type discussed above in relation to the embodiment of FIGS. 7A-G. Otherwise, the module bracket 200.sup.vii for the photovoltaic assembly 150.sup.vii may be installed on a standing seam in accordance with the discussion of FIGS. 7A-G. Other than the manner of attachment, the discussion presented above with regarding to the embodiment of FIGS. 4A-G is applicable to the embodiment of FIGS. 9A-G (and vice versa). However and since a mounting device 260 is used by the photovoltaic assembly 150.sup.vii in FIGS. 9A-G, the mounting clips 202, 204 for the module bracket 220.sup.vii will be maintained in spaced relation to the roofing surface 100 (more specifically, disposed in spaced relation to the upper end of the standing seam 114 to which the module bracket 220.sup.vii is interconnected).

[0141] A number of observations may be made with regard to the module bracket 200.sup.vii in relation to installing photovoltaic modules on the roofing surface 100. As the mounting clips 202, 204 are not offset from the base section 220 in the case of the module bracket 200.sup.vii, the module bracket 200.sup.vii does not provide the spacing provided by the embodiment of FIGS. 2A-L (although the use of the mounting device 260 does provide some level of enhanced spacing for the embodiment of FIGS. 9A-G). However, the entirety of the retention forces exerted by the module bracket 200v.sup.ii on the photovoltaic modules 120a, 120b continues to be provided by the mounting clips 202, 204 (no other forces are used to retain the modules 120a, 120b on the module bracket 200.sup.vii). Moreover, the mounting clip 202 may exert a compressive force on the second module flange 134 of the photovoltaic module 120a. Similarly, the mounting clip 204 may exert a compressive force on the first module flange 128 of the photovoltaic module 120b. As the module bracket 200.sup.vii also includes at least one least one electrical contact 218 for each of the mounting clips 202, 204, the corresponding discussion presented above with regard to the embodiment of FIGS. 2A-L is equally applicable to the embodiment of FIGS. 9A-G.

[0142] One embodiment of a method for installing photovoltaic modules will be addressed with regard to the embodiment of FIG. 2A-2L. It should be appreciated that this installation method is applicable to all embodiments described herein. Although this installation method will be described with regard to the building surface 100, it is equally applicable to the building surface 100 as well.

[0143] A plurality of first module brackets 200 may be installed in the above-noted manner on the roofing surface 100. As discussed above, the first mounting clip 202 of each module bracket 200 is installed on the building surface 100 in the up-slope direction A from its corresponding second mounting clip 204. The noted first module brackets 200 may be installed in a first row on the roofing surface 100, where this first row extends at least generally transverse to the pitch P of the roofing surface 100 (e.g., across the roofing surface 100; along a line that is disposed at a common elevation on the roofing surface 100). Any appropriate spacing may be utilized between adjacent pairs of first module brackets 200.

[0144] At least one second module bracket 200 (and more typically a plurality of second module brackets 200) may be installed on the second module flange 134 of the photovoltaic module 120a. More specifically, the first mounting clip 202 of each second module bracket 200 being installed on the photovoltaic module 120a may be slid onto the second module flange 134 of the photovoltaic module 120a (e.g., the second module flange 134 may be directed/slid between the first section 206 and its corresponding second section 208 of the first mounting clip 202 for each second module bracket 200 being installed on the photovoltaic module 120a).

[0145] The photovoltaic module 120a may be installed on at least one of the first module brackets 200 in the first row (typically at least two of the first module brackets 200 in the first row, and again that have been previously anchored relative to the roofing surface 100). Initially, the first module flange 128 of the photovoltaic module 120a may be positioned in the space between the first mounting clip 202 and the second mounting clip 204 of at least one of the first module brackets 200 in the first row. Thereafter, the first module flange 128 of the photovoltaic module 120a may be moved in the down-slope direction B to slide into the second mounting clip 204 of at least one of the first module brackets 200 in the first row (e.g., the first module flange 128 may be directed/slid between the first section 206 and its corresponding second section 208 of the second mounting clip 204 for each first module bracket 200 being used to install the photovoltaic module 120a on the roofing surface 100). The first module flange 128 of the photovoltaic module 120a may be simultaneously slid into the second mounting clip 204 of two or more of the first module brackets 200 in the first row. In any case, movement of the photovoltaic module 120a in the down-slope direction B may be terminated by the free end 128a of first module flange 128 of the photovoltaic module 120a engaging the end section 210 of the second mounting clip 204 for one or more of the first module brackets 200 in the first row.

[0146] After the photovoltaic module 120a has been installed on the first module brackets 200 in the first row in the above-noted manner, each second module bracket 200 (that was previously installed on the second module flange 134 of the photovoltaic module 120a) may be repositioned along this second module flange 134 (by sliding any given second module bracket 200 along the length dimension of the second module flange 134 for the photovoltaic module 120a) to align such a second module bracket 200 with the desired rib 104 of the roofing surface 100 (if required). Each second module bracket 200 on the second module flange 134 of the photovoltaic module 120a may also be slid in the down-slope direction B until the free end 134a of this second module flange 134 engages the end section 210 of its first mounting clip 202. In any case and with the second module brackets 200 being appropriately engaged with the second module flange 134 of the photovoltaic module 120a and also in the desired position relative to the roofing surface 100, each of the second module brackets 200 on the second module flange 134a of the photovoltaic module 120a may be attached to the roofing surface 100 in the above-noted matter. These second module brackets 200 may extend in a second row on the roofing surface 100, where this second row extends at least generally transverse to the pitch P of the roofing surface 100 (e.g., across the roofing surface 100; along a line that is disposed at a common elevation on the roofing surface 100), and where this second row for the second module brackets 200 is at least generally parallel with the noted first row for the first module brackets 200.

[0147] A variation of the foregoing would be to install the first mounting clip 202 of one or more of the second module brackets 200 on the second module flange 134 of the photovoltaic module 120 after installing the first module flange 128 of the photovoltaic module 120 on one or more of the first module brackets 200 (again, that have already been attached to the roofing surface 100), and thereafter anchor each such second module bracket 200 (on the second module flange 134 of the photovoltaic module 120a) relative to the roofing surface 100. The foregoing may be repeated any appropriate number of times to install a column of photovoltaic modules 120 down the pitch P of the roofing surface 100, where the column would extend in the dimension of the pitch P of the roofing surface 100 and where each subsequently installed photovoltaic module 120 in the column would be in the down-slope direction B from all previously installed photovoltaic modules 120 in the same column. Multiple columns of photovoltaic modules 120 could be installed on the roofing surface 100 in the above-noted manner as well (which could then define an array of photovoltaic modules 120 on the roofing surface 100, where this array would be in the form of a plurality of rows and a plurality of columns). As the embodiments were described herein with regard to a pair of photovoltaic modules 120 being installed on a common module bracket, at least part of the installation of a down-slope photovoltaic module on this module bracket (e.g., the second photovoltaic module 120b) will be described.

[0148] Subsequent in time to each of the following: 1) the first module flange 128 of the photovoltaic module 120a having been positioned in the second mounting clip 204 of one or more first module brackets 200 in the first row in the above-noted manner (where each such first module bracket 200 was previously anchored relative to the roofing surface 100); 2) the second module flange 134 of the photovoltaic module 120a having been positioned in the first mounting clip 202 of one or more second module brackets 200 in the second row in the above-noted manner; and 3) each such second module bracket 200 having been anchored relative to the roofing surface 100; the photovoltaic module 120b may be installed on at least one of the second module brackets 200 in the second row (typically at least two of the second module brackets 200 in the second row). Initially, the first module flange 128 of the photovoltaic module 120b may be positioned in the space between the first mounting clip 202 and the second mounting clip 204 of at least one of the second module brackets 200 in the second row. Thereafter, the first module flange 128 of the photovoltaic module 120b may be moved in the down-slope direction B to slide into the second mounting clip 204 of at least one of the second module brackets 200 in the second row (e.g., the first module flange 128 may be directed/slid between the first section 206 and its corresponding second section 208 of the second mounting clip 204 for each second module bracket 200 being used to install the photovoltaic module 120b on the roofing surface 100). The first module flange 128 may be simultaneously slid into the second mounting clip 204 of two or more of the second module brackets 200 in the second row. Movement of the photovoltaic module 120b in the down-slope direction B may be terminated by the free end 128a of first module flange 128 of the photovoltaic module 120b engaging the end section 210 of the second mounting clip 204 for one or more of the second module brackets 200 in the second row. One or more third module brackets 200 may be installed on the second module flange 134 of the second photovoltaic module 120b in the manner discussed above regarding the second module brackets 200 and the second module flange 134 of the first photovoltaic module 120a, and may then be anchored relative to the roofing surface 100 to complete the installation of the photovoltaic module 120b (e.g., to dispose such third module brackets 200 in a third row that is at least generally parallel to the noted first row for the first module brackets 200).
