Tesla started accepting deposits to reserve solar roof tiles in May 2017. In January 2018, the company announced that they are ramping up production of the roof product at their Buffalo Gigafactory. Then in mid March, they completed some of the first initial installations for customers at the top of their wait list in the California area approximately six months after their initial estimate.
Elon Musk revealed in August 2017 that he and another Tesla executive have installed the roof on their respective properties already. While the company has stated that they have begun installations for their wait list, it’s unclear when Tesla will be installing the roof at a national, mass market scale. Some estimates suggest large-scale installation won’t start until mid-2018 or later.
To give prospective solar roof customers more information, Tesla launched a calculator that provides estimates for its solar roof. The company has also released basic pricing information: customers can expect to pay around $21.85 per square foot for their solar roof.
