Tempered glass is used to make solar roofs, which are more than three times stronger and lighter than conventional roofing tiles. They do not deteriorate over time like concrete or asphalt do. The glass itself will be covered by a warranty for the duration of your home or infinity, whichever comes first. It is the most resilient roof currently on the market. Tesla’s founder, Elon Musk, declared in 2016 that his business would start selling solar roof tiles. Tesla’s Solar Roof is a game changer for the renewable energy sector. These tiles would blend in with standard roof tiles and be able to generate solar power. It is less expensive than a conventional solar panel system and resembles a typical roof in appearance.
