Solar panels, they're used to assist in illuminating road signs on the highways. Some are now coming out with mini wind turbines to.

In most cases they're solar panels. Particularly for school zones or bridge warnings. It allows for either the flashing lights or illuminated signs without running electrical conduit hundreds of miles.

The posts with the angled plates (they're very shiny and black, yes) are solar collectors, gathering energy to power the roadsign phone system.

I assume you mean like on light poles or such. Those are solar panels to charge batteries for whatever the device that is mounted.

They are solar panels for emergency phones. They keep the batteries charged so the emergency phones will always work.

I've seen those things and wondered too. I wonder if they're part of a cell phone network.
