Elon Musk claims Tesla’s solar roof will cost less than a regular roof

Tesla CEO Elon Musk says his company’s solar roof will cost less than a regular roof. And no, we’re not just talking about the long-term effects that come into play with producing your own energy via the roof. Musk says the upfront cost will be less, both when it comes to manufacturing and installing the roof. Musk was quoted in a Bloomberg report saying this after Tesla shareholders approve the acquisition of Solar City. He says electricity is now “just a bonus.”

But don’t expect these to be dirt cheap. These will still come at a premium price (which we don’t know yet). The terra cotta and slate roofs Tesla mimicked are considered among the most expensive roofing materials on the market—sometimes costing as much as 20 times more than cheap asphalt shingles. The cost savings though might be seen in the shipping of the materials. These new tempered-glass roof tiles are said to weigh as little as a fifth of current products and are easier to ship.
