Earlier quoted context omitted.

I did consider but there are 2 issues. 1. Efficiency. Not all roof parts can be exposed to sun. You overpay 2. You need to time it with roof change

Home insurance also (ie replacement cost after damaging weather event).

I can't help but think that this essentially ruled it out in much of the country -- i get the impression Tesla doesn't tend to consider Midwest markets in their initial engineering

The problem with solar roofs is that it combines a changing technology, PV solar, to something that does not change, roofs. So now every time the new technology advances you need to pay for the new PV cells and the same roof tiles again. Solar roof will work once the PV tech settles down. From 20% eficiency to 100% it's a long way to go.

Yep. Fred Lambert, the usual suspect.

He is very critical of Elon Musk, but I never caught him writing something false.

He is extremely negative about Tesla, consistently. He's careful not to open himself to lawsuit with plausible deniability. But he borderline lies. I won't be surprised if he's on the payroll of legacy auto

Aside from power-independence, does solar on residential roofs ever make sense? For all the complexity of doing a few houses, you could do an entire parking lot (or empty land) and power the whole neighborhood.

It's central vs decentralisation.

The electricy is consumed in the houses and not on the empty land.

Parking lots become a win-win with electric cars. They also keep the cars cleen and sun protected.

This current crop of tech bros and companies really is the worst for humanity. Failed tech and projects I can understand, but it’s the total, consistent and persistent lack of care and disregard for people, customers & the planet. They never clean up their own mess either, and I even disliked the kids who did that at playgroup 40 years ago!! The sole ambition is always money & power. I read that article aghast at mul…

The monstrous tech bros destroying humanity by bringing about electric cars, intelligent machines, mapping the world, bringing information to anyone anywhere. I on the other hand, Maximus Virtus, am a net gain to humanity when I hack into tech products for visualizing my home’s data.

And don't forget the cheap, reusable rockets. Effing tech bros.

Surely there’s a middle ground where a roof is made of something big and panel-sized, rather than a conventional roof with panels as another layer on top?

This is the roof of an industrial building near here which seems to go with that idea: https://nabendynamo.de/wp-content/uploads/2021/06/20210426_1... While not quite panel-sized, it's much larger tiles and there's not another roof underneath. Probably makes most sense with a new roof, though. The problem is that when a roof lasts 50--80 years, that's not a very big market just for new roofs.

Perfect. That scalloped (overlapping tiles) installation is The Correct Answer™.

Thanks for sharing.

Apologies, my google-fu is weak; I couldn't find more details. It's SON's building? I couldn't find that roof top at that address (using Google Maps).

Here's as far as I got: https://gemini.google.com/share/bef19f2b145c

Clearly they make economic sense or people wouldn't buy them.

Looks to be this building at that address and I can see the solar tiles on Google Maps: https://maps.app.goo.gl/ECbTUVwiUuDEPy6SA

The article from which I've linked the image is here (in German, though): https://nabendynamo.de/unser-neues-produktionsgebaeude-steht...

The roof is from Sunstyle, as detailed in the article: https://www.sunstyle.com/

Gemini seems to have read that article, taken a few details, embellished a few more, and not answered your question.
