USA – Tesla, the American car maker, energy storage company, and solar panel manufacturer announced the opening of orders for its solar roof tiles early in May.
The solar roof tiles form a Solar Roof system that integrates the solar cells and modules inside the structure of the roof rather than just panels on a roof was developed by Tesla and SolarCity.
“Solar Roof complements a home’s architecture while turning sunlight into electricity. With an integrated Powerwall, energy collected during the day is stored and made available any time, effectively turning a home into a personal utility. Solar energy can be generated, stored and used day and night, providing uninterrupted power even if the grid goes down,” a statement on Tesla’s website said.
The company also says that Solar Roof is more affordable than conventional roofs because in most cases, it ultimately pays for itself by reducing or eliminating a home’s electricity bill.
Consumer Reports estimates that a Solar Roof for an average size U.S. home would need to cost less than $24.50 per square foot to be cost competitive with a regular roof. The cost of Solar Roof is less. The typical homeowner can expect to pay $21.85 per square foot for Solar Roof, and benefit from a beautiful new roof that also increases the value of their home.
Tesla’s solar tiles use a high-efficiency solar cell manufactured by Panasonic and covered with a “colour louver film”, which allows cells to blend into the roof while exposing them to the sun above. The solar cells on the tiles are covered with tempered glass to give them durability.
“Made with tempered glass, Solar Roof tiles are more than three times stronger than standard roofing tiles, yet half the weight. They do not degrade over time like asphalt or concrete. Solar Roof is the most durable roof available and the glass itself will come with a warranty for the lifetime of your house, or infinity, whichever comes first,” Tesla explains on their website.
Furthermore, the solar power generation of the solar tiles is guaranteed for 30 years, which is on the higher end in the solar panel industry.
Tesla is making two types of tiles for its Solar Roof - solar and non-solar. Both look the same on a house from street level.
Depending on their electricity needs and shading from other structures around, customers can select how many solar tiles they need.
In keeping with Tesla’s mission to accelerate the world’s transition to a sustainable energy future, the company’s CEO Elon Musk concluded the announcement by saying, “When you think of a sustainable energy future, you want roofs to be beautiful and generate energy from the sun. That energy can then charge Powerwalls and electric vehicles. That’s the future we want.”
