So at $750 million a pop, that's a little over $550 billion to power US homes. Or, roughly 50% of the annual budget of the military to power all US homes for 80 years!

Clearly back of the envelope numbers, but definitely something to be excited about.

Well, you can't only have these things powering US homes because I can't imagine they work that well at night.

They do actually.

Truth be told, the article doesn't say how well they work at night. I don't think that it'll work just as good, but that doesn't mean it won't work at all.
