DETAILED DESCRIPTION

[0018] Structures and methods for supporting solar panels are provided. In accordance with some embodiments, these structures and methods can be used to support solar panels on a roof of a building. By elevating the panels above the top of the building, the roof can be accessed for the purposes of maintenance, recreation, or any other suitable purpose.

[0019] Turning to FIG. 1, an example 100 of a structure for supporting solar panels is illustrated. As shown, a set of solar panels 104 can be supported on structure 100. This structure can include a truss 101, verticals 114 and 118, and a tee extrusion 103.

[0020] A more detailed example of a portion of structure 100 is shown in FIG. 2. As illustrated, a solar (PV) panel 104 can sit on top of a ridge rail 206, and be secured to the ridge rail using end clamps 202, mid clamps (not shown), and screws 208. Any suitable solar panel can be used as panel 104. Any suitable clamps can be used as end claims 202 and the mid clamps. Any suitable screws can be used as screws 208, such as #14 gasketed self-drilling screws.

[0021] Ridge rail 206 can sit on top of truss 101. Truss 101 can be formed from outer truss members 210 and diagonals 216. Any suitable materials can be used to form members 210 and diagonals 216. For example, in some embodiments, members 210 can be formed from 2.52.50.25 aluminum square tubing. As another example, in some embodiments, diagonals 216 can be formed from 220.1875 aluminum square tubing. The members and the diagonals can be welded into a truss structure. In some embodiments, the truss can have angles 220 (27 degrees) and 222 (34 degrees) as shown, or any other suitable angles.

[0022] As shown in FIG. 2, a plate hanger 212 can be bolted to the truss. Hanger 212 can connect the truss to verticals 114 and 118 using bolts as shown. The plate hanger can be formed from any suitable material, such as 0.25 aluminum, in some embodiments. Verticals 114 and 118 can be formed from any suitable material, such as 220.25 aluminum square tubing. Any suitable bolts, such as stainless steel bolts, can be used to connect plate hanger 212 to truss 101 and verticals 114 and 118.

[0023] As shown in FIG. 3, at any suitable one or more points (e.g., such as the middle) along the length of verticals 114 and 118, support brackets 326 can be formed. As illustrated, in some embodiments, these brackets can be welded by a weld 324 to vertical 114 and welded by a weld (not shown) to vertical 118. The brackets can be made of any suitable material, such as 0.254 aluminum plate.

[0024] Similarly, as shown in FIG. 4, brackets 328 can be used to secure the bottom of verticals 114 and 118 to each other as shown in FIG. 4. Bracket 328 can be formed from any suitable materials, such as 0.254 aluminum plate. Bracket can be attached to verticals using any suitable approach, such as a weld 334.

[0025] A sleeve 330 can be attached to the bottom of vertical 114 as illustrated in FIG. 4. As shown, the sleeve can slide inside of vertical 114 and be bolted to vertical 114 by bolts 332. A notch 336 can be milled into the bottom of sleeve 330 so that the sleeve can engage tee extrusion 103. Sleeve 330 can be formed from any suitable materials, such as 1.5 square solid aluminum. Tee extrusion 103 can be formed from any suitable material, such as a 440.375 aluminum tee extrusion.

[0026] Tee extrusion 103 can be placed on top of shims 342 and bolted to roof rafters (not shown) using lag bolts 342. Shims 342 can be made of any suitable material, such as high-density polyethylene (HDPE). Bolts 340 can be made of any suitable material, such as stainless steel.

[0027] Turning to FIG. 5, an alternate view of structure 100 is shown. As illustrated, solar panel 104 is sitting on ridge rail 206 and is held in place by end claims 202 and mid clamps 544. Ridge rail 206 sits on truss member 210, which is bolted via truss 101 to plate hanger 212. Plate hanger 212 is bolted to verticals 114 and 118.

[0028] FIG. 6 shows an alternate view of the bottom of structure 100. As shown, verticals 114 and 118 are connected to tee extrusion 103 by sleeve 330, the tee extrusion sits on shims 342, and the tee extrusion is bolted to roofing rafters 646 by bolts 340.

[0029] As shown in FIG. 7, a connector tube 748 can be used to connect two ridge rails 206. The connector tube and ridge rails can be secured by bolts in some embodiments. As also shown, end clamps 202 and mid clamps 544 can be secured to the ridge rails using screws 208.

[0030] FIG. 8 is yet another partial view of structure 100.

[0031] FIGS. 9 and 10 show alternate views of the portion of structure 100 including solar panels 104, ridge rails 206, and outer truss members 210. As illustrated in FIG. 9, end clamps 202 can secure the solar panels to the ridge rail and the ridge rail can be secured to the outer truss members using screws 950. Likewise, as illustrated in FIG. 10, mid clamps 544 can secure the solar panels to the ridge rail and the ridge rail can be secured to the outer truss members using screws 950. Any suitable screws 950, such as stainless steel, corrosion resistant, self-drilling screws, can be used.

[0032] Still another view of the portion of structure 100 including solar panels 104, ridge rails 206, and outer truss members 210 is shown in FIG. 11. As illustrated, outer truss member 210 can be secured to the remainder of the truss via a welded gusset 1152.

[0033] FIG. 12 illustrates and example of two ridge rails 206 connected via a connector tube 748 and electrically connected by a grounding strap 1254. Any suitable ground strap can be used in some embodiments.
