He has just introduced
a new Powerwall with enough juice in it to run a two bedroom house (14 kWh) for a day, and hooked up to rooftop solar, can run indefinitely. (Although it will not charge the car, which needs 85 kWh or more) It is surprisingly affordable at US$ 5,500. This is a real game-changer, that erases
so many of the problems I have had with rooftop solar and its dependence on the grid,
the whole duck curve thing, just gone.
But what is getting all the pixels is that Musk has introduced a new solar roof shingle, in four different styles. They are made of tempered glass so that they are stronger and more durable than clay or slate or just about any other roof. they have a “micro-louvre” layer so that when you look at it from the street, you just see roof, but when you look at it from above, you see the solar cell.
The slate roof tile is made so that every one is different, with randomly generated patterns that make it look very real. They really are so beautiful that you can imagine, as Musk does, calling over your neighbors and saying “hey, check out my sweet roof.”
Musk says that “If you have a great solar roof, a big battery pack and an electric car, you can solve the whole energy equation.” He does not say what it costs, but notes that it will have a “lower cost than a traditional roof when combined with projected utility bill savings.”
They are nice to look at, which has never been something one has been able to say about rooftop solar.
He has done for solar panels what he did for electric cars: turned what were ugly and utilitarian into true objects of desire. Musk asks a valid question when he says they are “beautiful, affordable, integrated; if all these were true why would you go any other direction?”
