The at least one securing means 150 is slid through the horizontal groove 132 and inserted through the plurality of slots 152 on the plate member 148 and a plurality of apertures 154 on clamp member 146 to attach the clamp member 146 and the plate member 148 with the track 130 of the top slider 124. The at least one securing means 150 is tightened utilizing the lock nut 162.

(31) Then, the clamp member 146 interconnects the frame member 164 of the PV module 170 to the frame member 166 of the adjacent PV module 172 to provide a corner-to-corner coupling arrangement. Finally, the clamp member 146 is attached with the frame member 164 of the PV module 170 by inserting a plurality of screws 178 into a plurality of holes 157 on the clamp member 146. Thus, the corner-to-corner coupling arrangement enables the connection of PV module corners to adjacent PV module corners by sandwiching above and beneath the frame members 164, 166, 168 of the plurality of PV modules 170, 172, 174.

(32) FIG. 8 illustrates the base mount assembly 102 configured to adjust the mounting height of the rail-less roof mounting system 100 in accordance with the preferred embodiment of the present invention. The height of mounting of the rail-less roof mounting system 100 is adjusted by adjusting the position of the top slider 124 along the vertical engaging portion 114 of the block slider 110. The top slider 124 can be moved along the vertical engaging portion 114 and can be secured at desired position or height by tightening the at least one fastening means 140 through the vertical groove 120 on the vertical engaging portion 114 and the slot 138 on the sliding seal member 134.

(33) FIGS. 9 and 10 illustrate perspective and profile views of a PV array skirt 186 providing a snap-fit engagement with the rail-less roof mounting system 100 in accordance with the preferred embodiment of the present invention. A PV array skirt 186 is installed on an edge of a PV array. The PV array skirt 186 may provide improved aesthetics, safety and structural performance. The PV array skirt 186 may partially or fully obscure air gap and mounting hardware located beneath the PV array. The PV array skirt 186 may allow for the snap-fit engagement of the PV array skirt 186 to the rail-less roof mounting system 100. The rail-less roof mounting system 100 may also allow for the snap-fit engagement with the plurality of PV modules 170, 172, 174. The snap-fit engagement between the PV array skirt 186 and the rail-less roof mounting system 100 is achieved by inserting an extrusion 188 of the PV array skirt 186 along a grooved edge 147 of the plate member 148. Thus, the grooved edge 147 provides a seat for the extrusion 188 of the PV array skirt 186 to provide the snap-fit engagement. The snap-fit engagement provides a longer landing ability to the plate member 148 and an ability to easily clean out debris from under the PV array skirt 186.

(34) FIG. 11 illustrates a perspective view of interlocking of two PV array skirts 186 in accordance with the preferred embodiment of the present invention. The two PV array skirts 186 are placed end-to-end and ready to be interlocked together with a plurality of skirt clips 190. The plurality of skirt clips 190 is adaptable to prevent the PV array skirt 186 from sagging. The PV array skirt 186 may be manufactured from bent metal and may snap onto the rail-less roof mounting system 100 via the grooved edge 147 of the plate member 148. The rail-less roof mounting system 100 allows for vertical height adjustment therefore allowing for adjustment of height of the PV array skirt 186 above the roof structure 176 thus preventing the debris from entering the underlying air gap. A gap provided between the PV array skirt 186 and the frame member 164 may be sized in order to enable adequate room for installing the plurality of wire clips 163 or any other mounting structures.

(35) The embodiments discussed above allow for portrait orientation, landscape orientation or a combination of both. In a portrait orientation, the PV array having each of the plurality of PV modules 170, 172, 174 oriented, with the longest axis of the plurality of PV modules 170, 172, 174 extend in a forward-rearward direction, which is typically the south-north direction. The plurality of PV modules 170, 172, 174 have long edges with length running in cross-slope direction. It is noted, however, that the plurality of PV modules 170, 172, 174 can alternatively be oriented in a landscape orientation, that is, with the longest axis of the plurality of PV modules 170, 172, 174 extending in a lateral or side-to-side direction which is typically the east-west direction. Thus, the above-disclosed rail-less roof mounting system 100 can be used for gable roofs, hip roofs and flat and low slope gable roofs. The plurality of PV modules 170, 172, 174 have short edges with width running in cross-slope direction. Further, the rail-less roof mounting system 100 has the ability to cantilever the plurality of PV modules 170, 172, 174 for both portrait and landscape orientation, for example, 13 inch cantilever portrait and 19 inch cantilever landscape.

(36) The preferred embodiment reduces the number of parts, the size, and the cost of the parts, resulting in a total part count of approximately 151 (a 50% reduction) and a total mounting system hardware cost of $0.30/W retail (a 54% reduction). Further, the labor time to install the rail-less roof mounting system 100 is decreased by a minimum of 35%, which results in the reduction of installation times by over 55% as installation efficiencies grow. When the rail-less roof mounting system 100 is installed for bridging the plurality of PV modules 170, 172, 174, it is revealed a decrease of around 47% in non-electrical installation hours. Additional system design and procurement soft-costs are reduced by 67%, when utilizing the system.

(37) FIG. 12 illustrates one embodiment of a clamp assembly 196 in accordance with the present invention. The clamp assembly 196 is small in size and adaptable to use for end-clamping the plurality of PV modules 170, 172, 174. The clamp assembly 196 includes a clamp member 198 and a plate member 200. The clamp member 198 includes an aperture (not shown) on an inner surface 202 thereof and a pair of holes (not shown) to receive a pair of screws 204 and the plate member 200 includes a slot (not shown). The plate member 200 further includes a grooved edge 206 to accommodate the PV array skirt 186. At least one securing means 208 is inserted through the aperture (not shown) of the clamp member 198 and the slot (not shown) of the plate member 200 to engage the clamp member 198 and the plate member 200.

(38) The presently disclosed system is advantageous because it provides the corner-to-corner coupling arrangement, enabling the bridging of corners of the plurality of PV modules 170, 172, 174. The rail-less roof mounting system 100 provides a single grounding lug 175 for assembling the PV array consisting of 300 PV modules or less. Further, the rail-less roof mounting system 100 includes the plurality of wire clips 163, which are designed to work in multiple locations to minimize wire management issues. The rail-less roof mounting system 100 allows for more customizability in the PV array shape by allowing the installer to easily work around roof obstructions like vents, skylights, and other roof protrusions This rail-less roof mounting system 100 provides the ability to increase vertical leveling adjustability, for instance, 3 inch to 5 inch. The rail-less roof mounting system 100 has the ability to independently remove a single PV module without deconstructing an entire row of the PV array and allow for easy mounting height adjustment after the plurality of PV modules 170, 172, 174 are installed. The rail-less roof mounting system 100 can be easily assembled and disassembled and the components can be laid flat for easy storage and shipping. Furthermore, the rail-less roof mounting system 100 would require less manpower to install and rework.
