Over provision the panels by a good margin and have them at a more southerly angle (for northern hemisphere). You can play around on nrel pvwatts to see what configuration produces the most even expected monthly output: https://pvwatts.nrel.gov/pvwatts.php

Most solar charge controllers allow a certain amount of PV overprovisioning.

This is in the american southwest so winters are very mild and the sun is still strong. Summer is the much more demanding part where AC is 90% of electricity use for the year. There would certainly be challenges in other locations but I think you could do the napkin math on it with panels being as cheap as they are. The solution to pretty much any deficit these days is to just add more panels. The biggest issue there is, is if you do not have sufficient space. My panels are ground mounted.

Right now?

Using an overprovisioned quantity of cheap cells is part of it.

Insulating and air sealing your home well is part of it.

Thermal mass approaches are part of it. Without cheap batteries, it's very possible to store a great many kwh in volumes of soil, water, or sand riddled with pipes and resistive heaters.

This year it has been pointed out that vertical bifacial solar panels radically outperform tilted arrays if snow is a possibility. Expect this to be the new normal at high latitudes as cell area is very cheap now.
