Interesting so does "require a tool" include taking a screw off the cover plate of the combiner box, too? What a game changer. I'm going to Mexico for my next project; I'll actually enjoy even more being the sole AHJ on the project.

Readily accessible is now defined in the 2014 NEC. Installing OCPD's underneath a module is a major faux paux, and I can't imagine any AHJ thinking otherwise. Having to remove a module in order to reset a breaker, what a drag.

"Capable of being reached quickly for operation, renewal or inspection without requiring those concerned to use a tool, to climb over, remove obstacle or other."

You call it a solar panel, I call it a glass j-box cover plate.

If that is the interpretation,
I don't see how the breakers are "readily accessible" in a SolaDeck
mounted anywhere, regardless of whether it is under a module. It
requires removal of four screws (using a tool) to access the breakers
inside the enclosure. It's all up to the AHJ. It has not been an issue
locally here. I can see how other jurisdictions may not
concur.
