What is the variance of those estimators?

"Solar Roof uses two types of tiles—solar and non-solar. Looking at the roof from street level, the tiles look the same. Customers can select how many solar tiles they need based on their home’s electricity consumption."

Game changer for suburban housing. This will accelerate the decentralisation of power generation making it less likely power failure will occur. Now for housing regulations at state and municipal level to mandate solar tiles in construction.

Yikes. I just signed a contract for a new roof here last month, it's going to cost about $12k. Just did the estimate for the Tesla Solar roof... $80,300, so $87k if I want the battery too. I can barely afford the $12 right now, the $80 is just so far over it's not even close, even with how much I save over the years in electricity. That being said, I love these things, so hoping it gets cheaper in the coming years.

Take into account the fact that Model 3 + battery pack + roof will cost 80k-100k in 10 years. In France electricity cost almost double and fuel is 50% more expensive.

The hail ball test is deceptive. The tesla tile is held with more support since its horizontal. the max distance to any corner support is maybe 2-3 inches. the other natural tiles are vertical, and therefore have 4-5 inches to the farthest supported corners. It may still work, but we cant tell from that video.

> The hail ball test is deceptive.

In that case, Tesla is deceiving itself, since they offer unlimited warranty for the roof.

This is the dumbest thing ever. If you live in a city or a suburb, you don't need one of these things because you'll be connected to a grid that can give you electricity that is far more efficiently generated. If you live in a rural area with a lot of sun, then you can just put solar panels on the ground where they're not a bitch to clean.

I'm not against using solar electricity because it can be made affordable but this idea is equivalent to the backyard blast furnaces in Maoist China. It's a waste of time and only useful for status signaling to your eco-chic friends.

A bold claim indeed.

We're paying ~$19.5k for solar panels + installation. After the tax credit, that's $13,650 in cost. We spend ~$960/yr on electricity right now. The solar installation will cover all those needs, plus pay us $711/yr. So we're saving $1,671/yr. Pay off is thus ~8 years. The panels are good for 25 years. That's $28k in savings by the time the warranty runs out. They'll probably last longer. The batteries are a different…

That's much cheaper, than this article. Where is this?

Energy prices have been mostly flat relative to inflation for 40 years, and there's a reasonably good chance that they will start dropping appreciably (at least during peak daylight hours) as solar continues to make major inroads.

That's true in a lot of places but not really in California, where there's a lot of customers for solar. I don't need to go into the reasons why. It's California.

Why so? California's climate is pretty optimal for solar generation and there's a lot of desert waiting to be covered in solar panels.

Solar is not going to have a similar impact on (say) Ireland in the next 30 years.

Yeah good luck with that plan. ("Honey, if we get a solar roof it will help the planet, but we'll have to put junior in the cheaper preschool to pay for it. Whatya think?")

It's unfortunate that people can't see that junior dealing with the effects of climate change in 30, 40, 50 years could be a lot more devastating to his life than the prestige level of his preschool.
