Rooftop solar is nice for resiliency and can have its place in a grid, but it's not cost effective. Grid-scale solar is what most folks are talking about when they say solar boom. Even in the somewhat backwards US, where Solar in total is ~340TWh, the majority (~250TWh?) comes from grid-scale interconnected solar and solar+battery installations. Hopefully this gap continues to grow as the Biden-era IRA fueled grid-scale solar projects mature through their design/build/deploy pipelines in the coming years. Thinking of national policy from a home owner perspective is expected, but it isn't always instructive. For the latter item, my Rivian has a relatively paltry 1500W inverter with standard 110W plugs in the back seat, truck bed, and gear tunnel, but I can use a rectifier/power supply to pull a constant 1kW, step that back to DC and feed it into my home's battery backup system. My whole house tends to use ~2kW at peak, and obviously can conserve in outages. So I get my normal 4kWh battery bank with solar hookups, but can splice the 141kWh Rivian battery in, too, for a good chunk of off-grid power.
