You could weld a large flange plate onto the bottom of your pole, and bolt it to the granite using anchor bolts. Rock climbers (including myself) drill into granite all of the time. Bosch, among others, has a great drill and bit setup that works well. Glue in epoxies are a great way to keep moisture out of the hole for many years.</div><div dir="auto"><br></div><div dir="auto">Ballast racks are available too but it seems like a shame not to attach to the granite in some way.</div><div dir="auto"><br></div><div dir="auto">Good luck</div></div><br><div class="gmail_quote"><div dir="ltr">On Thu, Apr 12, 2018, 7:28 AM Aaron Mandelkorn <<a href="mailto:reosolar@gmail.com" rel="noreferrer" target="_blank">reosolar@gmail.com</a>> wrote:<br></div><blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex"><div dir="auto">Hi all,<div dir="auto"><br></div><div dir="auto">I have a customer that requires a mounting option I have yet to encounter. His site sits on top of of a massive hill of granite. It is relatively flat. Are there any mounting options that could work here? We are only talking about (12) to (16) modules for an off grid array. Is there anything that can bolt to rock? I typically use dpw or Mt solar pole mounts but can't imagine how these options could work.
