The solar roof business has always struck me as the “...and we’ll also have a city on Mars” part of the Tesla car business. It’s just seems like an economic non-starter to me. These kind of moves seem to underscore that; they don’t seem to care about the actual business, which would require creating a lot of trust over a long period of time. This isn’t like buying a new laptop, or even a new car: you’re talking about trusting someone’s word with the roof to your home and its primary power source for the next 20-30 years.
