Whole industries are going to pop up to take advantage of the intermittent very cheap electricity. Also there will be a competitive balance between the cost of storage and the "cost" of non-optimally aligned solar panels.
The other discouraging part is that as I understand it it's tricky to build the systems out a little at a time, e.g. start with five panels and no battery, add another five panels and batteries to the mix a few months later, add another ten panels another year later, stuff like that, without ending up with a lot of duplicated equipment and kind of a mess of an installation.
Especially if you're not trying to achieve an off-grid/backup solution, microinverters keep your install and additions simple.

Also, when you start small you don't need or have any use for a battery. Produce less than you consume or be happy with a little bit of waste and you don't need the complexity of a battery.
There are plenty of well planned paths towards a slow accumulation of pieces and features.
