In general I mean the cities, not just particular inspectors as far as requirements that aren't in the NEC. And, yeah, I see what you were saying about the cities needing to go through a process.
It's a case of picking battles I guess. I have argued, and won, about some significant things like when they want additional grounding rods that shouldn't be required. But, I've let other things go, like when they want direct burial grounding lugs on each module and not some less expensive clips which are also approved and make for a neater install.
The biggest specific impediment that some cities adopt for solar have been fire set backs. Some cities are much more strict than others. I guess this is a planning issue though and not the building department's.
