DETAILED DESCRIPTION OF THE DRAWINGS

[0033] In preferred aspects as illustrated in the various figures, the present system provides a solar mounting system 10 this is transported in, and mounted onto, a shipping container 20. Mounting system 10 is stored within the shipping container prior to deployment and includes: laterally extending beams 30 that extend outwardly from the top of shipping container 20 to beyond the sides of the shipping container; support mounts 40 connected to the laterally extending beams 30 at positions over the top of the shipping container; a first set of (higher) longitudinal beams 50 spanning between support mounts 40; a second set of (lower) longitudinal beams 60 spanning between ends of the laterally extending beams 30 at positions beside the shipping container; and a plurality of PV module support rails 70 extending between the first and second sets of longitudinal beams 50 and 60, with PV modules 100 mounted onto the PV module support rails 70 such that the PV modules slope downwardly from above the center of the shipping container to positions beyond the sides of the shipping container.

[0034] FIG. 1 is a perspective view of the present system in a deployed position and FIG. 2 corresponds to FIG. 1, but has the solar PV modules removed such that the present mounting system can be better seen. Referring first to FIGS. 1 and 2, a shipping container 20 is first transported to a remote jobsite. An ideal site for positioning shipping container 20 is determined. Once shipping container 20 has been placed at the desired location, various components (that are stored therein) are removed and construction begins, as follows.

[0035] First, laterally extending beams 30 are first secured onto the top of shipping container (as best seen in FIG. 2). It is to be understood that laterally extending beams 30 may each be one single integral I-beam or may be assembled from a plurality of separate shorter beams. Beams 30 need not be I-shaped, but may have other cross sectional shapes as well, keeping within the scope of the present invention. It is also to be understood that although FIGS. 1 and 2 illustrate three laterally extending beams 30 (with one beam at each of the font, back and middle of shipping container 20), the presently claimed invention also encompasses embodiments with different numbers of laterally extending beams 30 at different locations along the top of the shipping container. Laterally extending beams 30 are positioned on top of shipping container and extend across the top of shipping container 20, and extend outwardly from the sides of shipping container 20 as shown.

[0036] As seen in FIGS. 2, and 3A to 3D, support mounts 40 are connected onto laterally extending beams 30. As can be seen, support mounts 40 are positioned over the top of shipping container 20 and near the top center of shipping container 20. In accordance with the present system, support mounts 40 may be attached to longitudinal beams 30 by any means or system of connection. In one embodiment, ¼ turn corner locks may be used to attached support mounts 40 to longitudinal beams 30. However, other fastening and connection systems may be used instead, all keeping within the scope of the present invention.

[0037] As can also be seen in FIG. 3A, additional support mounts 41 can be positioned at the outward ends of laterally extending beams 30, as shown. In preferred aspects, support mounts 41 can be made of the same construction as support mounts 40, and operate in the same manner. Therefore, in various aspects, support mounts 40 are used to secure (upper) longitudinal beams 50. Similarly, support mounts 41 are used to secure (lower) longitudinal beams 60. Although support mounts 40 and 41 may preferably operate in the same manner, it is to be understood different mount designs may be used, all keeping within the scope of the present invention.

[0038] FIGS. 3C to 3E illustrate the operation of one of support mounts 40, as follows. In FIG. 3C, the support mount 40 in an open position prior to receiving the upper longitudinally extending beam 50 therein. Next, FIG. 3D shows the support mount 40 in an open position after upper longitudinal beam 50 has been received therein. Lastly, FIG. 3E shows the support mount 40 in a closed position around upper longitudinal beam 50, with upper longitudinal beam 50 locked firmly therein.

[0039] As can be seen, each support mount 40 optionally comprises: a stationary first portion 42 shaped to cradle one of the longitudinally extending beams 50, and a moveable second portion 44 also shaped to cradle the longitudinal extending beam 50. During assembly, the longitudinally extending beam 50 is first set onto the stationary first portion 42 and then secured into position by moving the second portion 44 of the support mount from an open to a closed position. As can be seen, beam 50 is preferably cylindrical such that the first and second portions 42 and 44 of the support mount are curved to together wrap round the longitudinal beam (regardless of the position of beam 50 around its longitudinal axis). Simply put, longitudinally extending beam 50 is simply dropped into support mount 40 without having to be rotated into a preferred position first. In preferred aspects, a locking pin 45 can be included and is received through the first and second positions 42 and 44 of the support mount to prevent second portion 44 of the support mount from moving after it has been moved into its closed position. In addition, another locking pin (not shown) can also pass through portions 42 and 43 at location 43 to prevent motion between portions 42 and 44. It is to be understood that other exemplary locking pin type connections and configurations can be used as well, all keeping within the scope of the present invention. The advantage, however, of these various embodiments and systems is that a secure system for holding longitudinally extending beam 50 into support 40 is provided using a minimum amount of hardware. Thus, the attachment of the ends of longitudinally extending beams 50 onto supports 40 can be carried out very quickly and easily.

[0040] Lower longitudinally extending beams 60 can be similarly attached onto support mounts 41 using the same equipment and configurations described above. It is also to be understood that in various embodiments, upper longitudinally extending beams 50 and lower longitudinally extending beams 60 can comprise single long beams extending the full length of shipping container 20 or may comprise a series of shorter beams positioned end to end. For example, in the illustrations of FIG. 2, two upper beams 50 may be used (one extending from the front to the middle of the shipping container, and the other extending from the middle to the back of the shipping container), and two lower beams 60 may also be used (one extending from the front to the middle of the shipping container, and the other extending from the middle to the back of the shipping container).

[0041] As also seen in FIG. 2, the first set of longitudinally extending beams 50 is positioned higher than the second set of longitudinally extending beams 60. As a result, the PV module support rails 70 (FIG. 3) are positioned to slope downwardly from the center to the sides of the shipping container. This sloping orientation for the PV modules 100 ensures a desirable angle of tilt of the PV modules with respect to the ground which provides wind resistance and rain drainage from the top of the modules.

[0042] FIGS. 4A and 4B show an optional vertical support member 80 on the side of the shipping container with the laterally extending beam 30 fastened on top. Vertical support member 80 is also seen in FIGS. 1 and 2 and is positioned at the mid-point of shipping container 20. A bracket 81 can be used to secure vertical support member 80 to the side of the shipping container and bolts 82 can be used to secure laterally extending beam 30 to the top of vertical support member 80.

[0043] After beams 30, 50 and 60 have all been secured into position, the PV modules are attached thereto, as follows. As seen in FIGS. 5A to 5E, module support rails 70 are secured to both upper and lower longitudinally extending beams 50 and 60, and PV modules 100 are attached on top of module support rails 70. FIG. 5A shows the positions of module support rails 70. FIG. 5B shows a perspective close-up of a module support rail 70 with a PV module 100 secured on top. As can be seen, module support rail 70 can be an extruded section of material having an upper groove 72 and a lower groove 74 extending therealong. As seen in FIGS. 5C and 5E, and L-shaped support bracket 73 can be slidably attached onto module support rail 70. Specifically, L-shaped bracket 73 may have a protrusion 76 extending therefrom which is received into upper groove 72. Bolts 78 may be secured into lower groove 74. As best seen in FIGS. 5D and 5E, a U-shaped bracket 75 may be used to secure L-shaped bracket 73 onto longitudinally extending beam 60.

[0044] In preferred aspects, the clamping system and method used to secure the lower ends of module support rails 70 to lower longitudinally extending beams 60 can be the same connection system used to secure the upper ends of module support rails 70 to upper longitudinally extending beams 50. After module support rails 70 have been securely positioned (as seen in FIG. 5A), the PV modules 100 can be attached. As seen in FIG. 5B, the attachment of PV modules onto module support rails 70 can be accomplished quickly and easily using bolt-type module clamps 71. As can be seen, each module clamp 71 can be positioned adjacent to a side edge of a PV module frame 100. Preferably, as seen in FIG. 5D, a single module clamp 71 can be used to secure the side edges of two PV module frames 100. Specifically, a lower module can be installed first (with a module clamp 71 holding its lower side). Next, another module 100 can be added (with another module clamp 71 simultaneously holding the upper side edge of the first PV module and the lower side edge of the second PV module).

[0045] FIGS. 6A to 6C show the shipping container 20 sitting on top of (and fastened to) laterally extending ground supports 110. Ground supports 110 extend laterally outwardly to the sides of shipping container 20 in the same direction as the PV modules extend. As such, laterally extending ground supports 110 provide stability against wind loading. In optional aspects, clamps 105 are used to connect ground supports 110 to the bottom of shipping container 20.

[0046] Lastly, FIG. 7 is a cut away a perspective view showing various optional components and equipment stored within shipping container 20. It is to be understood that the present system is not limited to any particular equipment or components being stored in shipping container 20. As such, in addition to the present mounting system, its associated beams, rails, fasteners and PV modules, additional equipment may also be stored in shipping container 20. For example, equipment needed to install a remote water treatment facility or a desalination system may be included. As can also be appreciated, the interior of the shipping container 20 may be used as a system control room with various electrical and logic components installed right onto the interior side walls of the shipping container.
