If you decide to go out of the grid almost completely, and buy batteries to store your energy. Have any idea about how much you'd spend?

  Even with recent developments, being totally off-grid only makes sense when it's your only option (remote rural cabin, etc). Solar panels with enough battery backup, plus an alternate generator (gas or diesel) for times when it's overcast for longer than your battery reserve are still going to have a very long payback time if utility power is an option. There's a reason utilities exist, after all. It's always been possible to have your own electrical generator, it's just way more cost-efficient to do that at utility scale. That will likely continue to be the case with solar and batteries.
