Here is some data from 2019 about cheap solar+storage. Per unit, it is always cheaper to build a factory than do home installation.

That's 3000 cycles before it gets to 80% efficient. Also battery studies in EVs have shown the cycle count to vastly underestimate the degradation.

Yeah, but at about a cycle a day, that’s 10 years, which is when the warranty in all the other stuff gets dicey.

obviously this isn't installed, nor 4500, but in case you weren't aware of how close things are getting already:

of course utility scale beats that handily.
