Just like any other house – but it’s got a SOLAR ROOF

No One Saw Tesla’s Solar Roof Coming Elon Musk just showed us the grand unification of Tesla: Fast cars, big batteries, and a stunning solar rooftop. Bloomberg,  Tom Randall October 31, 2016  “…….. This is the future of solar, Musk proclaimed. “You’ll want to call your neighbors over and say ‘check out the sweet roof.’ It’s not a phrase you hear often.”

The roof tiles are actually made of textured glass. From most viewing angles, they look just like ordinary shingles, but they allow light to pass through from above onto a standard flat solar cell. The plan is for Panasonic to produce the solar cells and for Tesla to put together the glass tiles and everything that goes along with them. That’s all predicated on shareholders approving the $2.2 billion acquisition of SolarCity, the biggest U.S. rooftop installer, on Nov. 17.

Tesla says the tempered glass is “tough as steel,” and can weather a lifetime of abuse from the elements. It can also be fitted with heating elements to melt snow in colder climates. “It’s never going to wear out,” Musk said, “It’s made of quartz. It has a quasi-infinite lifetime.”

In a Q&A with reporters after the presentation, Musk said the tiles are comparable to competing high-efficiency solar panels. The current prototypes that Tesla engineers are working with reduce the efficiency of the underlying solar cell by just 2 percent. With further refinement, Musk said he hopes the microscopic louvers responsible for making the tiles appear opaque can be used to actually boost the efficiency of standard photovoltaic cells.

Putting the pieces together

The vision presented at Universal Studios in Los Angeles is the grand unification of Musk’s clean-energy ambitions. The audience was able to step into a future powered entirely by Tesla: a house topped with sculpted Tuscan solar tiles, where night-time electricity is stored in two sleek wall-hung Powerwall batteries, and where a Model 3 prototype electric car sits parked out front within reach of the home’s car charger.

Attracting less attention on Wisteria Lane was Tesla’s Powerwall 2, a major upgrade of its home battery for electricity storage. …Version 2 is a much different product. It packs more than twice the capacity—14 kilowatt hours versus 6.4 kilowatt hours—for a cheaper price after installation. 1 It includes a built-in Tesla-brand inverter and comes with a ten year, infinite-cycle warranty. ……https://www.bloomberg.com/news/articles/2016-10-31/no-one-saw-tesla-s-solar-roof-coming?cmpid=google
