Dave,
I remember your post from earlier in the year and just went back and read it again. How did you end up securing your panels? I guess I am looking for an easy solution that doesn't require a lot of work, running wires, drilling into the shells (and potentially messing something up!), etc., and allows for moving the panels into the sun when parked in the shade.
I already inventoried all of the different light bulbs and plan to replace them with LEDs that are available on Amazon. Not sure about the fluorescent fixtures yet, but I am looking at these:
