Tesla发布Powerwall 2与Solar Roof

0:08Hey everybody

0:09My name is London arrive on the CEO of Solar City. I'm very excited about the products we're gonna be announcing today

0:17The products you'll see is a joint collaboration between Solar City and Tesla

0:21I want to thank the team for really putting this together and such a certain amount of time really appreciate their help and getting this done

0:28But to really understand the vision it's welcome Elon Musk

0:51Yeah, no fuzzy Jack at this time

0:54So I was sort of by just talking about the reason why we're doing this, which is, as you may

1:01have read, we're reaching records CO2 levels. Global warming is becoming a serious crisis,

1:09and we need to do something about that. But just like with electric cars, where electric cars

1:18electric cars originally, they didn't look good.

1:21They had low range.

1:22They didn't have good performance.

1:25They were like a golf cart.

1:26And some people had a real hard time buying electric cars.

1:29And I think something similar needs to happen to solar.

1:34We really need to make solar panels as appealing

1:37as electric cars have become.

1:40And the interesting thing is that the houses you see around you

1:45are all solar houses.

1:47I don't know if you know that.

1:48Or if you did you notice?

1:49Yeah.

1:50Yeah.

1:51Yeah.

1:54So we're talking in detail about each of them.

1:57But the goal is to make, have electric solar roofs that look better than normal roof,

2:06generate electricity, have lasts longer, have better insulation, and actually have a cost,

2:12an installed cost that is less than a normal roof plus the cost of electricity.

2:17And then why would you buy anything else?

2:20So let's get into the details here.

2:24So obviously, you saw the chart there probably familiar with

2:29that chart that came from NASA about how we're in vertical

2:33climb on CO2 levels.

2:35And we need to do everything we possibly can to accelerate

2:40the transition to sustainable energy.

2:42Save a sea lawn.

2:43So the goal of Tesla, people sometimes think of Tesla as an electric car company, but really

2:52the whole purpose of Tesla was to accelerate the advent of sustainable energy.

2:57It's not like there was a shortage of car companies in the world, there were plenty of

3:01good gasoline car companies, but there weren't good electric cars.

3:06That's really what was needed.

3:08So there are really three parts to the solution.

3:13So we go to what is the future that we want?

3:17It consists of a really appealing solar roof.

3:22Then combined that with storage and with electric cars.

3:27So it's an obvious three-part solution.

3:32Yeah, three-part solution.

3:37It's really not that complicated.

3:39Now, you need battery packs because the sun does not shine

3:42at night.

3:44And the point that we're at right now

3:47is in fact, obviously, a transition.

3:48We're transitioning from day to tonight, it's dusk.

3:53And so what's happening is that the houses

3:57are transitioning from the roof generating power

4:00to the battery pack, the power wall, producing power.

4:05So during the day, you fill up the battery,

4:09and then at night, and in dusk and dawn, you use the battery.

4:14It's pretty straightforward, really.

4:16It's like, not that complicated.

4:19You just need both.

4:23But if you have a great solar roof,

4:26and you have a battery affecting your house,

4:28and you have an electric car, that's

4:30something that scales worldwide.

4:32That you can solve the whole energy equation with that.

4:37So yeah.

4:40Obviously, next slide, please.

4:45So we'd like to introduce the power wall too.

4:50This is a big step above the power wall one.

4:53It has twice as much energy, more than twice as much power.

4:58So it's a 14 kilowatt hour energy storage,

5:027 kilowatt power output.

5:06And just to put that in basic terms, you can take a four-bedroom house

5:10And you can have, you can power your fridge, the sockets and lights for a day.

5:16And if you have solar on your house, you can power it indefinitely.

5:20So that's just with one.

5:23And then on the utility side, we've got the power pack two,

5:34which similarly doubles the energy.

5:36So it's a 10 kilowatt hour capability, 50 kilowatt power output.

5:42And this can scale to unlimited size.

5:46So it's, in fact, we've recently announced the biggest

5:51utility battery installation in the world, which is going to

5:55be with Southern California Edison.

5:57Let's go to the next slide.

6:00So we have an 80 megawatt hour battery installation that's

6:04being built right now.

6:10And then we announced one earlier this year, which is for

6:14utility in Hawaii doing 52 megawatt hours,

6:18you can see a lot more of these announced over time.

6:21And I think it's important to,

6:23I sure people appreciate that the solution

6:26is both local power generation

6:28and utility power generation.

6:30It's not one or the other.

6:31Sometimes the solar roof is positioned

6:35as a sort of a competitor to utilities,

6:38but we're actually gonna need utility power to increase,

6:43And we're going to need local power generation, because if you transition all energy to electric,

6:51that roughly triples the amount of electricity that's needed.

6:54So you need about a third for transport, about a third for heating, and about a third

6:59for what we currently use as electricity.

7:01So the future is bright for utilities and for local power generation.

7:07I would expect it to be roughly a third local power generation, roughly two-thirds utility.

7:13So it's, I think, a very bright future for utilities and for rooftop.

7:21So let's take a look at some of these roofs.

7:23As I mentioned earlier, what we're really looking for here is how do we have a solar roof that

7:28is better than a normal roof?

7:31That looks better, lasts longer, has better insulating effect, and where the cost of roof

7:39plus electricity is less than that of a normal roof.

7:43Now this is sort of the integrated future.

7:47You've got a electric car, a power wall, and a solar roof.

7:55And the key is that it needs to be beautiful, affordable,

7:58and seamlessly integrated.

8:01And then if all those things are true,

8:03why would you go any other direction?

8:13So yeah.

8:17So we're going to show you this is the before shot of that

8:18house over there.

8:21So that's what it looked like before.

8:22Now that's all solar.

8:27Yeah.

8:32I think we've got some close-up shots that we can show.

8:40And if you look carefully, you can actually see the solar

8:43cells behind the glass.

8:46So this is a textured glass tile.

8:49If you look carefully, you can see the solar cells.

8:55Yeah, you can see that.

8:59So we have a malfunction on the LED.

9:02So take a look at the next house.

9:13That house is also solar.

9:16And that's sort of a style of a French slate, which is one

9:20of the hardest things to do.

9:21It's considered one of the best roofs you can possibly do

9:25is a conventional roof.

9:26So he said, well, can we make a French-late roof that's

9:32solo that looks as good or better than a conventional

9:36French-late roof?

9:37And we're able to do that as well.

9:39That's done with hydrographic printing.

9:41So each tile is unique.

9:44So the production process itself makes each tile

9:50special unique, a special flake tile.

9:52But the nice thing is that no two roofs will be the same.

9:59So it's not just cookie cutter.

10:01You can take any two roofs like that and they will look different because they are different.

10:15This is what the French-led hydrographic looks like.

10:20Let's see that.

10:33And then the third house is really transformative.

10:36Because believe it or not, that's what it looked like before.

10:43So we changed the roof and it's like, whoa, put that roof on, we've got to change the house

10:46too.

10:47So that tile is more of a modern look.

11:11And here you can really see as the angle changes that you can see the solar cells.

11:18So here we put a film with micro-lubers on it so that as the angle changes, it goes from

11:26transparent to opaque.

11:29So from the vantage point of the street or anywhere near the house, it looks completely

11:35opaque.

11:36But from the sun, it's transparent.

11:53And then probably the most surprising one is the Tuscan glass.

12:00So this is also solar panels.

12:02We put two versions of the Tuscan glass approach.

12:07All of the dark tiles have solar panels.

12:12So we interleave dark and light.

12:14And then the dark ones are the ones with solar panels.

12:35Again, you can see that the transparency changes quite a bit.

12:39So from the sun's vantage point, which tends to be high angle,

12:43you can see the solar cells.

12:45But as you change the angle to a shallow angle,

12:48it reverts to sort of an orangey color.

13:05So one of the other advantages of glass

13:08is that we can actually make it a lot tougher and last lot

13:12longer than a conventional roof.

13:14So just as a demonstration video,

13:17I'll show you what happens if you drop a big weight

13:20on a conventional roof tile and one of our glass tiles.

13:30So the solar roof went just, we wanted to look better,

13:41last longer, provide better installation,

13:43and cost less, all things considered,

13:45than a conventional roof.

13:48The solar is a huge market for the current solar systems,

13:53because if you're building a new house,

13:56or you're redoing a roof, then this is the way to go.

14:00But if you have a new roof, then you'd

14:03want to put solar panels on that roof.

14:05So there's two very distinct markets.

14:08And there's about four to five million new roofs in the US

14:12every year.

14:13And I think 20 times that number are worldwide.

14:17So you can imagine over time, as people replace their roofs

14:21with solar roofs, that the whole neighborhood,

14:24everyone would have solar.

14:25Like, why wouldn't you?

14:26Over time, every house would become a solar house.

14:31And it's a neighborhood where the aesthetics actually get

14:35better. So where you look around your neighborhood and that's what you want to have happen. So

14:44the key is really to make solar something desirable where if you install a solar roof

14:50in your house, you're really proud that you want to put it on the most prominent part of

14:55the house. You want to call your neighbors over and say check out the sweet roof. It's

15:01It's like not a phrase that you hear often.

15:04But that's the key to it.

15:08People really care about their homes.

15:09They love their homes.

15:11And they really want them to be better.

15:15And I think taking this approach, it can be.

15:18So that's where we're headed.

15:21And I hope you agree that's the future we want.

15:23Woo!
