Really, solar panels are just one solution of a home energy system.
Governments should be looking at regulating microgrids for all homes where solar, stationary battery storage, electric vehicle storage, and even diesel/gas generators or geothermal contribute.
As you say, if you don’t have a means for local storage and the grid is maxed out, your panels are wasting away their free energy by self-consumption.
Sodium-ion batteries will absolutely seize a portion of the market share, but I don’t think we’d want governments restricting building requirements to specific technologies. The analogy in solar panels would be governments restricting home requirements to polycrystalline silicon, when you have other 1st Gen PV types (monocrystalline), 2nd Gen (thin film CdTe), and 3rd Gen (thin film perovskite, organics).
Microgrid controllers would do the smart dis/charging that you’re talking about, as well as automatically dis/connecting from the grid and shutting on/off critical loads.
