没有什么比永远更美好，宝贝，我们可以拥有一切。

大家好，我叫林登·里夫。我是SolarCity的首席执行官。我对我们今天将要发布的产品感到非常兴奋。你们将看到的产品是SolarCity与Tesla共同合作的成果。我要感谢团队，真的在这么短的时间内把这一切筹备起来。非常感谢他们的帮助，以及完成这件事。

但要真正理解这一愿景，让我们欢迎埃隆·马斯克，各位。

对，这次没有毛茸茸的夹克。

所以这个。我先从谈谈我们为什么要做这件事开始，也就是，正如你们可能已经读到的，我们的CO2浓度正在达到创纪录的水平。全球变暖正成为一场严重的，是一场严重的危机，我们需要为此采取行动。

但就像电动汽车一样，最初的电动汽车会，它们不好看，续航里程低，性能也不好，就像高尔夫球车。因此，人们确实很难购买电动汽车。我认为，你知道，太阳能也需要发生类似的转变。你真的需要让太阳能板像电动汽车如今这样有吸引力。而且，这个，你知道，比如有趣的是，你在周围看到的全都是，我不知道你是否知道这一点。

你注意到了吗。

在详细谈论它们中的每一个时？但目标是制造、拥有比普通屋顶更美观、能够发电、寿命更长、隔热效果更好，并且实际安装成本低于普通屋顶加用电成本的电动太阳能屋顶。那么，你为什么还会购买别的东西呢？所以我们来讲，我们将在这里深入讨论细节。所以很明显，你们看到了那张图表，你们可能对那张来自NASA的图表很熟悉，它显示CO2浓度正处于垂直攀升状态，而我们需要尽一切可能加速向可持续能源转型。

拯救我们吧，埃隆。

所以Tesla的目标。Tesla。人们有时认为Tesla是一家电动汽车公司，但实际上，Tesla的全部宗旨是加速可持续能源时代的到来。

这并不是说世界上缺少汽车公司。有很多优秀的汽油车公司，但没有好的电动汽车。那才是真正需要的东西。所以，这个解决方案实际上有3个部分。所以我们转向我们想要的未来是什么。它包括一个真正有吸引力的太阳能屋顶。然后将其与储能和电动汽车结合起来。所以，这是一个显而易见的3部分解决方案。

对，3部分的解决方案。

这真的没那么复杂。现在你需要电池组，因为太阳在夜间不会照耀。而我们现在所处的时刻，事实上显然是一个过渡阶段。我们正在从白天过渡到今晚。现在是黄昏。所以正在发生的是，这些房屋正从屋顶发电过渡到由电池组，也就是 Powerwall 供电。因此，白天你把电池充满，然后在夜间、黄昏和黎明时，你、你使用电池。

其实非常简单。就是没那么复杂。你需要，你只需要，你两者都需要，而且，但是如果你有一个很棒的太阳能屋顶，你家里有一个电池组，还有一辆电动汽车，这就是一种可以扩展到全球的方案，你可以、你可以用它解决整个能源方程。

所以，对，显然。请放下一张幻灯片。

所以，所以我们想介绍 Powerwall 2。

这个，这是相比 Powerwall 1 的一大进步。它的储能量是其2倍，功率超过2倍。所以它有14、14千瓦时的储能量，7千瓦的功率输出。简单来说，你可以拿一栋有4间卧室的房子，你可以让、你可以、你可以为你的冰箱、插座和照明供电1天。而如果你的、你的、你的房子上装有太阳能设备，就可以无限期地为它供电。

所以这只需要1台。

然后在公用事业侧，我们有 Power Pack 2，它同样将储能量提升至2倍。所以它具备10千瓦时的容量，50千瓦的功率输出，而且它可以扩展到无限大的规模。所以，事实上，我们最近宣布了世界上最大的公用事业电池装置，它将与南加州爱迪生公司合作建设。请切换到下一张幻灯片。

所以我们有一个80兆瓦时的电池装置，目前正在建设中。

然后我们今年早些时候还宣布了一个项目，是为夏威夷一家公用事业公司建设52兆瓦时的装置。随着时间推移，你们会看到更多这类项目公布。而且我认为，我认为有必要确保人们明白，解决方案既包括本地发电，也包括公用事业发电。并非二选一。有时，这个太阳能屋顶被定位成公用事业公司的某种竞争对手，但实际上我们将需要增加公用事业电力，也将需要本地发电，因为如果你把所有能源都转变为电力，所需的电量大致会变成3倍。

所以交通运输大约需要1/3，供暖大约需要1/3，我们目前的用电大约需要1/3。因此，无论对公用事业还是本地发电而言，未来都是光明的。我预计大致会是1/3由本地发电，大致2/3由公用事业供电。所以我认为，公用事业和屋顶发电都有非常光明的未来。

那么，让我们看看其中一些屋顶。正如我之前提到的，我们在这里真正寻求的是，怎样才能拥有一个优于普通屋顶的太阳能屋顶，它更美观、更耐用，拥有更好的隔热、隔热效果，而且屋顶加电力的成本低于普通屋顶。现在这就是、这算是一种一体化的未来。你有一辆电动汽车、一台 Powerwall 和一个太阳能屋顶。

而关键在于，它需要美观、价格合理并且无缝集成。

那么，如果这些全都是真的，你为什么还会选择其他方向？

所以，对，那么我们要给你们看看。这是那边那栋房子改造前的照片。

所以，那就是它以前的样子。现在那整个屋顶都是太阳能的。

对，我想我们有一些可以展示的特写镜头。

如果你仔细看，如果你仔细看，实际上可以看到玻璃后面的太阳能电池。

所以这是一块纹理玻璃瓦。如果你仔细看，就能看到那些、那些太阳能电池。

对，看到了吗？

所以我们的 LED 出故障了。

所以。

让我们看看下一栋房子。

对，所以那栋房子也是太阳能的，那是一种法式板岩风格，这是最难做到的事情之一。它被认为是你用传统屋顶方式所能做出的最好的屋顶之一。所以我们说，那么，我们能不能做一个独立的法式板岩屋顶，让它看起来和传统法式板岩屋顶一样好，甚至更好？而我们也能做到。这是用水转印技术完成的。所以每块瓦都是独一无二的。

所以是生产过程本身让每块瓦都格外独特。一种特殊的雪花瓦。

但好处是，不会有2个屋顶完全相同。所以它并不只是用同一个模子做出来的。你可以拿任意2个那样的屋顶，它们看起来都会不同，因为它们确实不同。

这就是法式板岩水转印图案的样子。你们可以看到。

然后第3栋房子的变化确实是颠覆性的，因为信不信由你，那就是它以前的样子。

所以我们换了屋顶，然后感觉就像，哇，装上那个屋顶之后，我们连房子也得改一改。

所以那种瓦片更具现代感。

在这里你可以清楚地看到，随着角度变化，你能看到太阳能电池。

所以我们在这里覆了一层带有微型百叶片的薄膜，这样随着角度变化，它会从透明变成不透明。

所以从街道的视角，或房屋附近任何地方看，它都是完全不透明的，但从太阳到太阳看，它是透明的。

然后可能最令人惊讶的是托斯卡纳、托斯卡纳玻璃。所以这也是太阳能板，但我们为托斯卡纳玻璃方案做了2个版本。

所有深色瓦片都有太阳能板。所以我们把深色和浅色交错排列。然后深色的那些就是带太阳能板的。

同样，你可以看到透明度发生了很大变化。所以当你。从太阳的视角来看，通常是高角度，你可以看到太阳能电池。但当你把角度变为较小的角度时，它又会变回某种橙色。

所以，玻璃的另一个优势是，我们实际上可以让它坚固得多，使用寿命也比传统屋顶长得多。所以我们只是用一段演示视频，向你们展示如果把一个。把一个大重物砸在传统屋瓦和我们的一块玻璃瓦上，会发生什么。

所以。

太阳能屋顶不会只是。我们希望它看起来更美观、使用寿命更长、提供更好的隔热性能，而且，而且综合考虑下来，成本低于传统屋顶。

目前的太阳能系统仍然有一个巨大的市场，因为如果你正在建造新房或者重做屋顶，那么这就是合适的选择。但如果你。如果你有一个新屋顶，那么你会想在那个屋顶上安装太阳能板。所以这是两个截然不同的市场，美国每年大约有400万到500万个新屋顶，而我认为全球是这个数字的20倍。所以你可以想象，随着时间推移，当人们用太阳能屋顶替换自己的屋顶时，整个社区里的每个人都会拥有太阳能。

比如，为什么不呢？随着时间推移，每栋房子都会变成太阳能住宅。而且这是一个美观程度实际上会得到提升的社区。

所以，当你环顾自己的社区时，那就是你希望发生的事情。

所以关键其实是让太阳能成为人们想要的东西，如果你在自己家里安装了太阳能屋顶，你会真的为它感到自豪。你会想把它装在房子最显眼的地方。你会想把邻居叫过来说，看看这个超棒的屋顶。

这好像不是一句你经常听到的话。

这就是其中的关键。人们真的很在意自己的家。他们爱自己的家，也希望自己的家变得更好。而且我认为，采取这种方式，它可以做到，所以这就是我们的前进方向，我希望你们认同这就是我们想要的未来。

去它是。

我爱你在那我爱你我爱你我爱你。

感到寒冷为了每一个告诉我流动一切让我全身焕发光芒。

萨。

Nothing better than forever, baby we can have it all.

Hey everybody, my name is Lyndon rive. I'm the CEO of SolarCity. I'm very excited about the products we're going to be announcing today. The products you'll see is a joint collaboration between SolarCity and Tesla. I want to thank the team for really putting this together in such short amount of time. Really appreciate their help and getting this done.

But to really understand the vision, let's welcome Elon Musk, Everybody.

Yeah, no fuzzy jacket this time.

So the. I will start off by just talking about the reason why we're doing this, which is, as you may have read, we're reaching record CO2 levels. Global warming is becoming a serious, is a serious crisis and we need to do something about that.

But just like with electric cars, where electric cars originally would, they didn't look good, they had low range, they didn't have good performance, they were like a golf cart. And so people had a real hard time buying electric cars. And I think, you know, something similar needs to happen to solar. You really need to make solar panels as appealing as, as electric cars have become. And the, you know, like the interesting thing is that how you see around you are all, I don't know if you know that.

Did you notice.

When talking in detail about each of them? But the goal is to make, have electric solar roofs that look better than normal roof, generate electricity, last longer, have better insulation and actually have an installed cost that is less than a normal roof, plus the cost of electricity. So then why would you buy anything else? So let's get into, we're going to get into the details here. So obviously you saw the chart there, probably you're familiar with that chart that came from NASA about how we're in vertical climb on CO2 levels and we need to do everything we possibly can to accelerate the transition to sustainable energy.

Save us, Elon.

So the goal of Tesla. Tesla. People sometimes think of Tesla as an electric car company, but really the whole purpose of Tesla was to accelerate the advent of sustainable energy.

It's not like there was a shortage of car companies in the world. There are plenty of good gasoline car companies, but they weren't good electric cars. That's really what was needed. So there are really three parts to the solution. So we go to what is the future that we want. It consists of a really appealing solar roof. Then combine that with storage and with electric cars. So it's an obvious three part solution.

Yeah, three part solution.

It's really not that complicated. Now you need battery packs because the sun does not shine at night. And the point that we're at right now is in fact obviously a transition. We're transitioning from day to tonight. It's dusk. And so what's happening is that the houses are transitioning from the roof generating power to the battery pack, the, the power wall producing power. So during the day you fill up the battery and then at night and in dusk and dawn, you, you use the battery.

It's pretty straightforward really. It's like not that complicated. You need, you just need, you need both and, but if you have a great solar roof and you have a battery pack in your house and you have an electric car, that's something that scales worldwide, that you can, you can solve the whole energy equation with that.

So, yeah, obviously. Next slide, please.

So, so we'd like to introduce the Powerwall 2.

The, this is a big step above the Powerwall 1. It has twice as much energy, more than twice as much power. So it's a 14, 14 kilowatt hour energy storage, 7 kilowatt power output. And just to put that in basic terms, you can take a four bedroom house and you can have, you can, you can power the, your fridge, the sockets and lights for a day. And if you have solar on your, on your, on your house, you can power it indefinitely.

So that's just with one.

And then on the utility side we've got the Power Pack 2, which similarly doubles the energy. So it's a 10 kilowatt hour capability, 50 kilowatt power output, and this can scale to unlimited size. So it's, in fact, we've recently announced the biggest utility battery installation in the world, which is going to be with Southern California Edison. Just go to the next slide.

So we have an 80 megawatt hour battery installation that's being built right now.

And then we announced one earlier this year, which is for a utility in Hawaii doing 52 megawatt hours. You're going to see a lot more of these announced over time. And I think, I think it's important to make sure people appreciate that the solution is both local power generation and utility power generation. It's not one or the other. Sometimes this, the solar roof is positioned as sort of a competitor to utilities, but we're actually going to need utility power to increase and we're going to need local power generation because if you transition all energy to electric, that roughly triples the amount of electricity that's needed.

So you need about a third for transport, about a third for heating and about a third for what we currently use electricity. So the future is bright for utilities and for local power generation. I would expect it to be roughly a third local power generation, roughly two thirds utilities. So I think it's a very bright future for utilities and for rooftop.

So let's take a look at some of these roofs. As I mentioned earlier, what we're really looking for here is how do we have a solar roof that is better than a normal roof, that looks better, lasts longer, has better insulation, insulating effect and where the cost of roof plus electricity is less than that of a normal roof. Now this is, this is sort of the integrated future. You've got a electric car, a powerwall and a solar roof.

And the key is that it needs to be beautiful, affordable and seamlessly integrated.

And then if all those things are true, why would you go any other direction?

So, yeah, so we're going to show you. This is the before shot of that house over there.

So that's what it looked like before. Now that's all solar.

Yeah, I think we've got some close up shots that we can show.

And if you look, if you look carefully, you can actually see the solar cells behind the glass.

So this is a textured glass tile. If you look carefully, you can see the, the solar cells.

Yeah, see that?

So we have a malfunction on the led.

So.

Let's take a look at the next house.

Right, so that house is also solar and that's a sort of a style of a French slate, which is one of the hardest things to do. It's considered one of the best roofs you can possibly do as a conventional roof. So we said, well, can we make a French slate roof that's solo, that looks as good or better than a conventional French slate roof? And we're able to do that as well. That's done with hydrographic printing. So each tile is unique.

So it's the production process itself makes each tile especially unique. A sort of special snowflake tile.

But the nice thing is no two roofs will be the same. So it's not just cookie cutter. You can take any two roofs like that and they will look different because they are different.

This is what the French slate hydrographic looks like. You can see that.

And then the third house is really transformative because, believe it or not, that's what it looked like before.

So we changed the roof and it's like, whoa, put that roof on. We've got to change the house too.

So that tile is more of a modern look.

And here you can really see as the angle Changes that you can see the solar cells.

So here we put a film with microlubers on it so that as the angle changes, it goes from transparent to opaque.

So from the vantage point of the street or anywhere near the house, it looks completely opaque, but from the sun to the sun, it's transparent.

And then probably the most surprising one is that the Tuscany Tuscan glass. So this is also solar panels, but we put two versions of the Tuscan glass approach.

All of the dark tiles have solar panels. So we interleave a dark and light. And then the dark ones are the ones with solar panels.

Again, you can see that the transparency changes quite a bit. So as you. From the sun's vantage point, which tends to be high angle, you can see the solar cells. But as you change the angle to a shallow angle, it reverts to sort of a orangey color.

So one of the other advantages of glass is that we can actually make it a lot tougher and last a lot longer than a conventional roof. So we're just as a demonstration video, show you what happens if you drop a. Drop a big weight on a conventional roof tile and one of our glass tiles.

So.

The solar roof won't just. We want it to look better, last longer, provide better insulation, and, and cost less, all things considered, than a conventional roof.

There's still a huge market for the current solar systems, because if you're building a new house or you're redoing your roof, then this is the way to go. But if you're. If you have a new roof, then you'd want to put solar panels on that roof. So there's two very distinct markets, and there's about 4 to 5 million new roofs in the US every year, and I think 20 times that number worldwide. So you can imagine over time, as people replace their roofs with solar roofs, that the whole neighborhood, everyone would have solar.

Like, why wouldn't you? Over time, every house would become a solar house. And it's a neighborhood where the aesthetics actually get better.

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

So the key is really to make solar something desirable, where if you install a solar roof in your house, you're really proud of it. You want to put it on the most prominent part of the house. You want to call your neighbors over and say, check out the sweet roof.

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

That's the key to it. People really care about their homes. They love their homes, and they want them to be better. And I think taking this approach, it can be so that's where we're headed and I hope you agree that's the future we want.

To it's.

I love you in the I love you I love you I love you.

Feel cold for each tell me Flow everything Bring out a glow all over me.
