Transmission requirements don't go away with rooftop solar. In fact, they become a huge sticking point.
If customers need transmission at night, or even once a year, they still need all the infrastructure in place.

Like if you build a highway and everyone commutes at exactly 9-5 then that dictates how many lanes you need.
In places with air-con, the distributed solar reduces the peak on a daily and yearly basis.
Distributed batteries also help with this.
In grid lingo these are called "non-wires alternatives" or "non-transmission alternatives"
Would decide against having a spare tire on your car, just because your traditional 4 tires were still required?
I think there are a lot of valid arguments to have residential solar, but I'm just saying that the big picture economics aren't really there. You have to pay to maintain the commercial transmission and generating capacity, and then pay again for a more expensive redundant local system.
