Trouble is "don't use electricity after dark" is still unimaginable for most Americans.

That's one of the "benefits" of the steady crumbling of the world's infrastructure. Most of the world is used to routine scheduled power outages due to lack of resources and the US is soon to join that club. When people are used to not having electricity on demand and batteries get more expensive as we run out of lithium and rare earths, direct solar will be less of a hard sell.
