Could you convert electricity into a infrared laser and beam the energy into space?

A laser beam carries no entropy, so I don't see the point of this.

Using a laser beam to dissipate heat is one of those classic hard science fiction bloopers. David Brin is one guilty party (in "Sundiver").

You can skip the solar panel entirely and just lay out mirrors, or just spray the ground with white paint.
