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.

Plug in batteries where the battery itself is cheap af (like Australia) and the ability to charge it for free from the grid exists (like Australia) are a no brainer. When batteries are expensive and grid electricity is not free (the entire US) then it doesn’t really pencil out and requires the plug in solar but that has to be cheap too. Think used panels off Facebook marketplace type cheap. Like I don’t care about offsetting a portion of my energy for free with a 7-10 year payback. Plug in systems should pay for themselves in less than 2 years IMO.

Aussie here - exported 650+ kW to the grid last month from our solar, and consumed the remainder that was generated. Overnight covered entirely by battery.
