I just realized the biggest benefit is plug-in battery. A plug-in battery enables anyone to shift demand, taking advantage of cheap/free energy.

You can use a slightly intelligent app to decide whether to consume it yourself later, or sell it back to the grid. Australia has 3 hour free electricity, thats probably enough for some uses.

Plug-in solar may or may not be possible, but anyone can use a plug-in battery. If there are structures to support balcony solar or off grid panels in your backyard, then you can produce for free and charge your batteries.
