How do solar-powered establishments still have power when the sun goes down?

I don’t know how to flair this, so I’m tagging it as “Other”

Answer 1

If they’re 100% solar, then they tend to have a battery array to collect excess power into he day for use at night. Otherwise they’re mostly solar, using main grid power at night and solar in the day, but in that case they often still make more power than they need in the day so that power is flowing into the grid in the daytime since they’re connected to it so they break even, and if not break-even come pretty close.

Edit: I can’t spell godamnit.
