Machined Aluminum Z-Bracket Free 3D model

This 3D model was originally created with Sketchup 13 and then converted to all other 3D formats. Native format is .skp 3dsmax scene is 3ds Max 2016 version, rendered with Vray 3.00 This is a perfectly replicated machined Aluminum Z-type or zee bracket mount for mounting solar electric panels on walls or roofs.

Real world usage: Each panel of size up to 3’ x 6’ and smaller requires a minimum of 4 of these, 2 on each of the long sides of the panel, mount with panel side in, roof side out (so tools can reach screws, one of a couple of intended reasons for using this bracket). Use of these brackets precludes the necessity to use large heavy expensive sliding rail type rack mount setups.

Notes: In documentation for installation, and in real practice, these brackets should be placed as follows (looking at the panel flat, on its back at either long side): One bracket placed between the point of 20 to 30%25 of the way across the bottom edge and one bracket placed between the point of the 70 to 80%25 of the way across the bottom edge. Switch to the other long side and repeat for the total of 2 pairs of opposed brackets. One reason for not placing brackets at the very end of the panel is for heavier panels so their weight does not sag in the middle putting more leveraged bending stress on the brackets and their attached hardware. Note also the reason for not placing the brackets too close to the center of the panel is it would make the panels less secure in wind storms and more wobbly having too much of a centered anchoring point because the winds will whip over the roof, pulling at either side of the panel beyond the bracket mounts creating a teeter-totter effect of sorts. Bottom line is, don’t place the brackets too close too the middle or the ends of the panel because you want the panel to have the least amount of flex in any direction. You want its weight evenly distributed on both sides of each backet. The ideal position would be 25%25 and 75%25 of the way across the bottom edge on each long side. These are attached first to the panel frames, secondarily as an assembled panel with attached mounts to the wall or roof. Be sure to use lock washers with your screws and bolts on both holes on each bracket. Roof mounts will additionally require sun-resistant silicone and/or butyle rubber pads under brackets to do a water-tight installation.
