Solar Panel Unistrut Connection

I’m about to purchase the PV system for my bus. I’m going to be mounting 15/16” unistrut to the ribs with 1/4” carriage bolts, using these sealing washers I found on McMaster-Carr as shown in the screenshot, and extra sealant on top of the bolt/washer as extra insurance against leaks.

Then to mount the panel to the unistrut I don’t know what to do. I could use the Renogy Z clips, but they are too narrow to be compatible with unistrut and they would also add another inch of height and I’m trying to keep them as close to the roof as possible.

I thought about getting some flat stainless steel strip to screw to the back of the panel and then to the face of the unistrut or using some L shaped channel for a little cleaner look.

Please tell me what’s worked for you.

Thanks!

Any pics of the solar panels? Ours have a C-channel frame running around the perimeter with bolt holes on the bottom lip, so the bottom of the frame sits directly on the support (angle iron, in our case). We've got residential panels though, which might be different than yours. Pics might help though.

They’re predrilled on the back and warranty is void if more holes are made. This is the Renogy 100W compact panel.

I haven't used Unistrut, just remember looking at it in the hardware store but don't they have a Unistrut proprietary bolts and clips (spring clips of some sort IIRC?) that will allow you to bolt directly to the frame through those predrilled holes? Maybe that doesn't allow you enough room to get a wrench and hands under there though, now that I think about it. Ours are a good 3" off the roof.

The opening on the unistrut is too wide for the Renogy clips and the clips add an inch of height. I’m trying to keep the profile low.

Here’s the unistrut at the span of the panels

I guess what I was thinking is, using one of these spring bolts and bolt the panel directly to the unistrut. They've got SO MUCH Unistrut proprietary hardware, clips and whatnot, that there's gotta be something that'll work. Hopefully someone else will chime in with what's worked for them. If you haven't seen the Unistrut assembly demonstration video yet you should take a look. They show just about every conceivable connection that can be made.

Yeah, I’m overthinking it. I think these might work
