I don't really understand the resistance to Enphase on a roof (anymore, at least). We have many thousands of microinverters out there, and I don't even have a dedicated service department. We swap maybe 100 a year at the most at this point, and that includes for systems we didn't install. It's super quick and easy. But most of our roofs are single story 5:12 pitch on average.
I have at least a dozen small commercial sites with 100 - 500 units each, and I can't remembereven an handful of replacements on those over the years. I did get involved with a commercial site I did not install, and that was a nightmare, with over 100 early generation microinverters that failed. It was a custom rack, and the clamps were a nightmare, not to mention the array map had gotten out of whack over the years from prior micro swaps. But for the most part, I have no issue with micro swaps on roofs.
