Forgive me if this is a silly question but when he talks about "beautiful solar-roof-with-battery", is he talking about car roofs or roofs of buildings?

An electric car with a solar roof that charges all day would be pretty cool.

Buildings. A car roof isn't enough area and isn't pointed in the right direction.

Not if it's a trailer.

That clicked when he talked about Tesla Semi. A roof installation on the trailer would make sense and might generate a 'useful' amount of power.

That's a great point. I'd imagine they need 3-4 times the power of a car but have 100 times the surface area. It seems like that could actually work.
