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