Who gives a **** about Australia? It's a blip. Australians generally don't buy EVs due to the long travel distances and lack of charging infrastructure, so I'd expect Tesla at launch to do well in a tiny market. Are you desperately reaching for any good news you can find?

How do you know the bolded?
Grid connection is a lagging indicator (obviously). It took 3 months for the solar roof owner below to get connected, because of the utility company....Many sources back up that solar roof has been installed in 8 states. The worst you can say is that Tesla/Musk are late to deliver (but that is standard for Musk, he's wildly optimistic about time).
So you post a few shill videos and zero actual evidence that "100+" solar roofs are installed? As for the bolded, many sources quote Tesla claiming that they're "being" installed in 8 states, which is a lovely nonspecific claim. None claiming they've installed 100+ roofs. And we know that Musk has lied before on this topic; he fraudulently claimed "hundreds" during the conference call and they actually had 12 as Tesla later clarified. Oops.

As I think you pointed out recently solar PV making is a cut-throat business, with an undifferentiated product competing on cost. The roof might solve that issue.
By being far more expensive? Solar roof costs are insane, even with subsidized prototypes. The numbers Tesla and their shills give for normal roofing are pure fiction; they had a good laugh at Tesla's fraud comparison on some roofing forums that discussed it.
Solar roofs will never be economically viable or have much demand for several reasons:
- Installation cost is insane. For an existing roof you have to pull it all up. Which means it only makes sense in greenfields or roof replacements. But greenfields are cost sensitive and a $100K roof when you can do it for $20K makes no sense.
- It comes with unknown and very real fire risks that regular tiles do not, especially with the Walmart news going mainstream.
- As a solar solution it stinks - the cells have far worse economies of scale than the solar panel industry, are less efficient and more prone to overheating, aren't appropriately sized for the house (your power is a function of your roof size and orientation), and fully half of the panels will be on the wrong side to catch the sun in the northern hemisphere!!!!!! Half the damn panels will be shaded outside of summer. One of the few test customers they installed the roof on is a perfect microcosm of how this makes no sense at all:
2/3 of that roof is shaded most of the day and half is on the wrong side for facing the sun, which means you're installing ultra-expensive non-solar shingles on most of your roof for no real gain. You can get the same power output with more-efficient panels cited in the right place for far lower cost and disruption. Then there's this:
Quote:
While traditional solar panels can be installed in a day, it took a team of 10 to 15 workers two weeks to install this roof.
Forgetting the insane cost of this, you can have solar panels in a day on your existing roof or ultra-expensive solar shingles with 2 weeks of disruption.
Way smarter and more capable people and companies than Musk/Tesla have tried solar roofs and found it not viable. They just don't make sense.
You'll get a bunch of loser fanboys who want a "Tesla roof" but there isn't a large scale market for these things, the economics are just way wrong. You can get a Model 3 + a normal roof + solar panels and a large battery system for less than the cost of a solar roof. That says it all really.
