The only good part of a Solar City PPA is that if the system doesn't produce, you don't pay.
...and that's why I did a 64 panel 16kW Solar City install in 2013 under a PPA--I knew I would pay more in the end, but if the system did not produce power, that it would not be my nickel. A couple of years ago Tesla Energy replaced a SolaeEdge inverter that died (...and they figured out that it failed, not me).
Now I have 2 Powerwalls from Tesla Energy and all is linked together (...and I pay more attention to my solar production).
