It's probably a fact but
misleading. Here is what Elon Musk said about the Solar Roof in the Aug 2 conference call:
"We now have several hundred homes with the Solar Roof on them, and that's going well. It takes a while to just confirm that the Solar Roof is going to last for 30 years and all the details work out, and we're working with first responders to make sure it's safe in the event of a fire and that kind of thing. So it's quite a long validation program for a roof which has got to last for 30, 40, 50 years, but we also expect to ramp that up next year at our Gigafactory 2 in Buffalo. That's going to be super exciting. If there's a company with a better product roadmap, I'd like to know where it is, because we've got some super awesome stuff coming."
My guess: California is probably not the state Tesla uses primarily to test the Solar Roof, which makes sense at the current stage if we consider how far Buffalo is from California.
Is that the impression we got from the 'facts' the troll cited?
Rule #1: trolls will generally only cite facts to mislead and to distort the discussion.
