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.
