![]() On the other hand, the French slate shingles are works of art. Still, they’re a sweet option compared to no solar at all. As shown on the sample roof, the Tuscan-style tiles would seem to have the least efficiency of the styles, as only the darker tiles are collecting solar energy and they are only doing so on the flat parts (not the curves). So they’re not quite capturing the authentic aged Tuscan look or full efficiency. Note to engineers: Tesla is hard at work to solve the efficiency problem the curves present, but it’s true the curves are still a technical drawback. So it was very impressive to see the curved tiles included in the presentation. The delicate terra cotta tiles don’t take well to having holes drilled in them, and conventional solar panels actually look exceptionally horrible in such stark contrast to the terra cotta tiles.

It’s from 2015, so the numbers have most likely changed a bit, but it’s still useful for some perspective on cost and especially cost per kWh of storage. Here’s a nifty cost analysis of various batteries and grid power. The shingles will be available by summer 2017. Elon Musk stated that, combined with a $5,500 Powerwall 2, the solar shingles will actually be cheaper than buying conventional shingles and electricity from the grid. The Tesla solar roof was the biggest news, but the Powerwall 2 & Powerpack 2 are game-changers as well. He’s kept going, and won’t stop till he reaches his retirement community on Mars. Most mere mortals would’ve given up many times along the way. Riding there, I passed a Tesla Roadster and was overcome with awe at how far the company has come since the Roadster. But I did get to hitch a ride in a swanky Model X, which was a lovely way to start the Tesla world experience. The event was primarily for Tesla owners, so it took me longer to get up the hill from the studio gate than it did to ride my Zero from Vernon at rush hour. (You can watch the full video of the presentation further down in this article if you didn’t already watch it in Steve’s article, on , or elsewhere.) These were paired with new Powerwall home batteries that have double the energy density of Tesla’s first Powerwall product. Last night, on a back lot at Universal Studios, Tesla unveiled the most promising facet of its impending merger with SolarCity - solar roof tiles as chic and efficient as their cars.
