Tesla just announced a new range of solar roof tiles/shingles that function as both a solar collector and the tile itself. The photovoltaic cells are embedded in the tempered glass tile, which is considerably stronger than existing roofing tiles. They look really good too, and come in a range of finishes. I admire Elon Musk, despite his aspirations to put people on Mars. It's this kind of innovation that will push renewables to the next level.
The tiles coincide with the release of the Powerpack 2, or is it Powerwall 2, I'm not certain, maybe one is commercial, the other non commercial.
A link to the video of the launch event is below.
