Flexable solar panel UNDER rear seal

[rickst29]

Flex panels have a bad habit of dying for no reason at all, and such a panel is much more likely to "croak" if the front shell's seal is pressing on them and scratching them.

Why not the front shell?

You could lay a flex panel across the seam with careful taping. (NOT pressing sharply into the bends around the seam between street-side and curb-side.) I did that about 5 years ago (front shell seam), and that "centered" flex panel is still working well.
