I'm building a slide-out panel system for my Class B RV, and I need some advice. I have two large panels measuring 44" x 68" (1723mm x 1135mm) that I plan to slide out from the short side, which restricts my support options. I'm considering using a 35mm x 35mm angle iron or aluminum to create a cradle or frame for the panels. Would this setup provide enough support to avoid sagging, assuming the panels are attached securely to the frame? For reference, here's the panel spec: [Mission Solar PDF](https://www.missionsolar.com/wp-content/uploads/2024/08/MSE-PERC-108HC.pdf)

It sounds like a good plan to use the angle iron or aluminum for support. I'd recommend adding two support poles to attach to the side of the sliding panel, kind of like how an awning works. This will help stabilize the panel as it slides out. Trying to float such a big panel could lead to issues down the line!
I get the idea with the support poles, but keep in mind that you'll need to support it from both long sides if possible. If the panel were laying flat, it would be stable, so creating a cradle similar to that should offer solid support!
