Tesla Inc. has kicked off production of its long-awaited electricity-producing shingles that Elon Musk says will transform the rooftop solar industry.
Manufacturing of the photovoltaic glass tiles began last month at a factory in Buffalo built with backing from New York State, the company said in an email Tuesday. It comes more than a year after Tesla unveiled the shingles to a mix of fanfare and skepticism.
The appeal: a sleek, clean solar product, especially for homeowners seeking to replace aging roofs. The tiles -- from most angles -- look like ordinary shingles. They allow light to pass from above and onto a standard flat solar cell.
Tesla, the biggest U.S. installer of rooftop-solar systems, piloted the product on the homes of several employees. The company expects to begin installing roofs for customers within the next few months.

I'm in Florida, on the coast. Our houses are concrete.
Insurance companies like complicated shapes because the simple shapes were badly done. Simple shapes are strong when done right.
Consider the traditional 2-pane shape, a pair of rectangles joined at the top. The durable and obvious way to construct this is with walls (concrete in Florida) that go up to the roof. Two walls would be rectangles, and two walls would have a peak on top that makes them pentagons. This can be built with tilt-up construction.
That isn't what people built. People made all 4 walls rectangular, then added flimsy wooden triangular wall extensions on top of two of the walls. Those bits of junk would fail. Well duh... but don't blame that on the roof shape.
Concrete houses are not lifting in hurricanes. They may lift in tornadoes. The solution to that is to sink the foundation deeper. You want walls that are continuous concrete from an inch below the roof surface down to several feet under ground. Tornado resistance might not be realistic. We'd like it, but it takes some serious construction.
