You simply overspec the site by perhaps 2% to allow 2% of units to fail and the whole system is still working to specification.
Then you design the replacement procedure for the battery or inverter modules to take 10 seconds per module and swapping the faulty ones out only takes a few man-hours per year even for a gigawatt scale installation.
but a DISASTER in residential.
Now they will be a 'pure play' in Robotics & AI !
I love this scene from Silicon Valley:

This show was really ahead of its time. "If you show revenue people will ask how much and it will never be enough" /s Imaginary trillions of revenues from Optimus are definitely much more appealing.
However unlike Space X where they do test launches, Tesla most likely just pushes products out to public and lets the public beta test them.
Self driving is a whole another thing. I would trust Comma AI autopilot before I would trust Teslas (even though every time Hotz speaks he glazes Elon), because at least you can tell that Comma has actual smart people that think about the code they are writing.
I bet all contracts are conveniently missing the word "guaranteed"
