Yes, just to be clear, I wasn’t intending to recommend the flexible panels from Renogy. Here’s the compact design I was thinking of, seems to be a bit longer and a bit narrower

These are the panels I got, the high efficiency version, a bit shorter.

With any panel, you can run aluminum angle the span between and into the tracks and attach the panel to that, just maybe get the 1/4” stuff for rigidity. That way, you can run any sized panel you want.
