Aaron, Have you considered drilling into the rock and gluing anchor bolts or 'pinning the rock with rebar and building rebar cage and concrete on that? There are ways but engineering supervision is required. Good Luck!

--Aaron,I have seen large pole mounts in Portugal in an above ground ring of concrete 3 feet high and 6 feet in diameter. I would get an engineers opinion on the size but that would be easier than digging a hole in rock.David KatzOn Thu, Apr 12, 2018 at 6:27 AM Aaron Mandelkorn <[email protected]> wrote:Hi all,_______________________________________________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. Any thoughts?Aaron Mandelkorn
