I think this is a very uncharitable interpretation of that 'illustration'. The illustration makes no explicit claim that the energy is produced by the solar panels on the roof, let alone solar power. And I think it goes without saying that heavy industry cannot be supported by a small cluster of panels. There are even wind turbines in the picture, which further discredits the idea that Musk is trying to imply the solar panels can do it alone.
