You got a $12K quote for tile? How long is the warranty? Remember that the 80K quote includes solar, so you'd have to add a standard solar install of the same KW capacity to your initial quote to really compare apples to apples. You'll probably still pay a premium to go with Tesla, but the no-profile solar integration and lifetime warranty really look attractive. Some people are probably willing to pay for it, simila…

No, I just want a new roof. I wasn't planning on installing Solar. Solar was supposed to be a perk of buying the roof from Tesla...and all of this was supposed to cost as much as a roof alone.

Cite? Tesla (at the product launch) actually said it was about as much as buying a new, premium roof + electricity.

I'm so absolutely excited for solar power. Tesla's Solar Roof, their PowerWall batteries, electric cars. It's all just painting such a bright future. Certainly Tesla has no monopoly on it, but they've made it sexy and are pushing the bleeding edge forward. Props to them. We recently signed a contract to do an installation on our house (with a local contractor, not SolarCity). It can't happen soon enough! We'll have e…

I'd double check my math, because economic law says that's unlikely.

Does anyone understand how the warranty works? From their solar panel page[0], it says that there is a 30 year warranty for Power and Weatherization and a lifetime warranty. So, what does the lifetime cover? The only thing that can go wrong is that either the power module fails or the tile is damaged due to weather, which is both covered by the 30 year warranty. Nevertheless, a 30 year warranty is still pretty impres…

The tiles are proof against weather: if you saw the reveal video they dropped a heavy object on a tile without damaging it. Given that, offering a warranty against weather damage is basically free to Tesla, modulo manufacturing defects.

And unless you live in a forest, or in tornado alley, having an anti-weather warranty for your roof is worthless. Most roof problems are caused by mistakes in installation, not because the tiles don't last as long as they are expected to.

I don't really see the selling point, or value here. Tesla's calculator estimates $40,500 for a roof that generates half our power needs, and should provide $20,400 worth of energy over 30-years. Add in a PowerWall and federal tax credit, and I'm still losing $15,400 over 30-years. If I put that same $40,000 in an index fund that got the stock market's historical 7% average, and waited 30 years, I'd have $308,000. To…

Wait what, their estimated payback time is 60 YEARS? This is terrible. They've gotta be just trying to snipe rich early-adopter-for-the-status types.

Tesla? The company that brought you the Roadster first, then the Model S and X, and only later the Model 3? I'm shocked. ;)

People keep overlooking the objective value of not relying on "grid" power sources. Power goes off, your system keeps going. Gasoline supply stops (I've seen that a few times), you can just power your car at home. Your system fails, grid is likely still up to cover. Supply-and-demand takes a sharp turn when supply is actually limited and can/does run out . At that point, having pre-paid for your own uninterrupted off…

If your city's electricity and gasoline supplies have stopped for any appreciable length of time, you will have far more serious problems then 'I've only got 120 miles of gas in my tank.'

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.

Wouldnt increasing the tag price of your home by 15k to absorb the loss when you sell compensate? Also, in 30 years, 15k will be worth less than 15k today.

Why don't banks (or even Tesla for that matter) finance such roofs upfront? It seems they can make money out of this.

Low repo value, unless you put your house up for collateral.

And whats wrong with that? A bunch of rich early-adopter-for-the-status types will get a Telsa roof, Telsa will get better at developing the technology and the price will come down, meanwhile more people are moving to renewable energy sources to power their homes which is good for the environment. Whats the downside here?

Through the tax credits, we're all paying for someone else's pet project.

Since Tesla's products are expensive, it would be a regressive tax even if we all bought enough solar panels for our needs.

I'm curious about the durability - I live Colorado Springs, which is typically very sunny (good for solar), but can get pretty bad hailstorms. This means that the average roof lifetime here is much shorter than elsewhere. If the Tesla's roof tiles are actually significantly more durable than asphalt, it could be more cost-effective here than elsewhere.

>If I put that same $40,000 in an index fund that got the stock market's historical 7% average, and waited 30 years, I'd have $308,000. Are you doing the math all in present dollars? Because the return is 7% after inflation but >10% before. So you'd have >500.000 in 2047 dollars. In this case it's important to do that adjustment because you're doing an investment upfront for payoffs over 30 years so the value of mone…

Energy prices, and thus savings, are certain to increase over that 30 years too. Quite likely at a rate exceeding inflation.
