Elon Musk announced the new Tesla solar roof tile yesterday, which will allow homeowners to collect abundant power without needing large solar panels attached to their roof.
The tiles are composed of three layers. The top layer is a tempered glass that is extremely durable and impact resistant. The middle layer is a color louver film that allows the cells to blend into the roof, while exposing them to the sun above. The bottom layer is a high efficiency solar cell that produces energy even during high temperature days.
The tiles should last about 2 to 3 times longer than a conventional asphalt tile, though Musk has stated “they should last longer than the house”.
The solar roof tiles come in four looks to match any architectural style. Each of these looks do a good job of resembling its conventional roofing material counterpart. The tiles are transparent to solar, but appears opaque when viewed from an angle where most people will be viewing the roof.
1. Textured Glass Tile
2. Slate Glass Tile
3. Tuscan Glass Tile
4. Smooth Glass Tile
The key to a successful solar powered house is storing the energy effectively. Tesla has developed a new version of their Powerwall battery that can power a two-bedroom home for a full day. The unit is compact, stackable and has a built-in inverter. Installation of the Powerwall 2 is simple and it can be placed either indoor or outdoor making it suitable for any home installation.
One 14 kWh Powerwall battery costs $5,500 plus installation.
The Tesla solar roof tile product isn’t currently available, but should be by the summer of 2017. Tesla plans to start with one or two of its four tile styles – as seen above – then gradually add new styles over time. Sign up for updates on Tesla’s home energy solutions here.
