The other issue is that ground fault protection (GFP) is now readily
available and must be included on roof-top mounted PV arrays on houses.
This was always required but was not often enforced previously as there
was not listed hardware available to meet this requirement. 

Greetings Christopher,

One thing I always wondered in regards to the GFP requirement.  My PV
modules are mounted on the south side of my house.  Mounted just above
the downstairs window which means when I make seasonal adjustments to
the array, doing so also offers more shading of the summer sun to the
downstairs windows, and when I tilt them down in the Fall they let the
winter sun in.

In any case, the way I read the letter of the code, I don't need GFP,
but by the spirit of the code, I'd guess I do.  BTW, I don't.
