<div dir="ltr"><div>Some more ideas:</div><div><br></div><div>If you want to go custom, you should be able to through-bolt to the bottom of the module frame with standard stainless hardware per the manufacturer instructions. Here is an example from <a href="https://us.sunpower.com/sites/sunpower/files/media-library/manuals/mn-sunpower-solar-panels-safety-installation-guide-na.pdf">SunPower's installation guide</a>:</div><div><br></div><div>"Frame Holes: Secure the module to the structure using the factory
mounting holes. Four 1/4\u2033 stainless steel bolts, with nuts, washers, and lock
washers are recommended per module; tightened to a min. torque of 10 inlbs. Refer to Table 4 for the module dimensions and hole locations. This
method has been certified by a third-party organization according to UL
1703. For frame hole mounting, modules must be secured using the holes
located at 322mm from the short end of the module for 72 and 96 cell
modules and 433mm from the end of the module for 128 cell modules. For
carport installations the supporting structure has been pre-drilled. For 128
cell modules for carport assembly, modules must be secured using only the
holes located 433mm from the ends of the module and hardware described
above in Section 4.1, Item 5. See Figure 2 for carport assembly details."</div><div><br></div><div>We typically spec out an EPDM pad or washer between the module, rail, and or sub rack system to avoid dissimilar metal corrosion unless the materials are all the same.</div><div><br></div><div>For wire management, there are more and more clips available on the market designed to secure wiring without needing classic zip ties. Maybe your AC module manufacturer has accessories? When cable ties are needed, I always like using the <a href="https://www.heyco.com/Solar_Power_Components/pdf/SunBundler-Cable-Ties.pdf">Heyco Sunbundler</a>.</div><div><br></div><div>Just some thoughts,</div><div><br></div><div>August</div></div><br><div class="gmail_quote"><div dir="ltr" class="gmail_attr">On Fri, Feb 8, 2019 at 6:37 AM Jason Szumlanski <<a href="mailto:jason@floridasolardesigngroup.com">jason@floridasolardesigngroup.com</a>> wrote:<br></div><blockquote class="gmail_quote" style="margin:0px 0px 0px 0.8ex;border-left:1px solid rgb(204,204,204);padding-left:1ex"><div dir="ltr"><div class="gmail_default" style="font-family:arial,helvetica,sans-serif">I don't think I'm going to get the spans I need in this high wind area with an off-the-shelf aluminum solar rail.
