Watch how Tesla Solar Roof automatically makes snow slide right off
A new video shows how Tesla Solar Roof automatically makes snow slide right off it to be able to keep producing electricity.
Tesla Solar Roof
Solar Roof is Tesla’s solution to deploy solar power on brand-new houses or houses that are in need of a new roof.
Homeowners that are soon going to need a new roof generally don’t want to install rooftop solar panels since they are going to need to be removed during roof replacement.
To remedy the situation, Tesla designed glass roof tiles with embedded solar cells resulting in a roofing product that is long-lasting and produces electricity.
After a few delays to test the product for longevity, reduce cost, and improve installation times, Tesla has started to ramp up installations of the solar roof in the last year.
Early installations were in markets like California and Florida where snow is rare, but now that installations are ramping up, we see more of them up north where snow is going to be a common occurrence on those solar roofs.
People have some misconceptions about solar in colder climates, like that it only has value in places that get a lot of sun.
Solar power systems indeed produce more energy in regions that get more sun, but they also work well in less sunny places.
They even produce some energy in very cloudy weather as photons from the sun will still get through, but if your solar power system is covered in snow, it will not generate energy.
But that doesn’t mean that rooftop solar installations are not useful in the winter.
Solar panels produce some heat that can help snow melt or slide off the roof faster by creating a layer of water to help gravity after an accumulation from a snowstorm.
While it’s true of solar panels, it’s also true for Tesla’s solar roof tiles, which makes it interesting since, unlike solar panels, they cover the entire roof.
Now we see an interesting early example of it.
Jason Lassen, a new Tesla Solar Roof owner in Wisconsin, shared video of his roof during and after a snowstorm:
As you can see, while the snow accumulated briefly, it slid off the Tesla solar roof while neighboring houses still had snow-covered roofs.
Interestingly, it quite uniformly slid off the roof despite the fact that some of the tiles have solar cells embedded in them and some don’t.

LIFESTYLE HOME GARDEN HOME Bill Gates and Melinda’s 27-year-old marriage has come to an end. Picture: Anthony Bolante/Reuters Inside Xanadu 2.0: Take a sneak peek into Bill and Melinda Gates’s Washington mansion By Staff Reporter May 11, 2021 Questions have been asked as to who is likely to get Bill and Melinda Gates’ 6 100² lakeside mansion in Washington State once their divorce is settled. But it would seem Melinda doesn’t really want it. In a profile in Fortune magazine published in 2008, she said when she arrived in Gates’ life the house caused her to have “a mini sort of personal crisis”. It was partly built when she married Gates in 1994. She described it as “a bachelor’s dream and a bride’s nightmare… with enough software and hi-tech displays to make a newlywed feel as though she were living inside a video game”. So with the help of interior designer Thierry Despont – who has worked on the Palm Court of New York’s Plaza Hotel, and the Ritz in Paris – she helped create a home
