Hey everyone! I recently bought some used commercial-grade solar panels that are 46mm thick, which seems thicker than most racking systems I've seen out there. I'm looking for recommendations on a shingle roof racking system that can accommodate this thickness, specifically for the mid and end clamps. I live in Maryland, so I'd like something that meets the standard snow and wind ratings. Any ideas or solutions would be greatly appreciated. The panel model is SPR-E320-372-COM!

I've been diving into options for 46mm clamps since I got some SunPower panels too. There are a few options available, but it's not like there’s a ton of information out there. If you search for '46mm end clamp' or '46mm mid clamp', you might find something that fits your needs. Just a heads up, you may need to piece together your own setup instead of finding a complete kit.

It’s wild how complicated it can get! I felt the same way while searching for info. Let’s keep each other posted if we find anything useful!
