When you say cupping, plastic haze, etc, are you referring to the flexible panels? My biggest concern with them is that they are bonded to the roof rather than fastened. That means no holes, but how would a panel be replaced should it fail?
I had interstate charge and test my batteries. Turns out they are brand new but are a little small (60 amp-hour so they said). They recommended a bigger bank next time. Mine are HD24-DP.
If your main concern is holes in your roof there are ways to secure regular glass panels to the roof with glued down methods.

This is one way.
