Australia is a rich country with a high proportion of home owners and a high proportion of stand-alone homes (rather than flats).  It is a very sunny country, and has high and volatile electricity prices.  So amongst the richer segment of the population, you will get a lot of solar panels, and a fair proportion of these will have batteries.  It is also amongst those richer people that you will see electric car ownership, probably in addition to fossil fuel cars.  Thus you see a correlation. If and when electric car ownership spreads significantly in Australia, that correlation will disappear as people living in flats, apartments, smaller houses, etc., get electric cars - they will not have solar panels, or house batteries.

 Flats and apartments don't have solar panels or batteries at the moment. There a certain amount of agitation to work out ways of making this possible. The building committee that control my apartment block isn't all that interested at the moment - they are still working out how to provide charging points for electric cars parked in our basement parking, but it's going to happen eventually.

In Spain, they do.
First the association of owners decides how many panels to put with the goal of covering common usage, like elevators and passage lighting, with or without batteries. If there is still surface available on the roof, individual owners can install a number of panels that is virtually connected to their flats, with or without batteries. In the case of individuals, the generation can also compensate different properties of that person even in different cities.
It is just a matter of regulation. :-)
