It is nice when a few houses do this in a neighborhood, but when more do it then the electric company is going to get challenges that come with the high demands of power.

Electrifying everything in a whole city will come with very expensive infrastructure changes. Especially if every house can also be a supplier so the amps can ramp up in different cables every time

(Also wow, your solar panels are expensive. Is that inc. Battery? I put down 4kw systems for about 3-4k 10x400wp panels)
