Corrected entry: Sojef states that his people came from a Solar System on the brink of war. This would technically be the Sol System, which is where Earth resides. Star Trek traditionally would refer to other systems properly as a generic "star system". (00:38:20)

Correction: He can say it however he wants to. Just because something is normally said one way, doesn't mean others can't say it another way.

That doesn't address the mistake. The mistake is that he calls it a "solar system." The term "solar system" does not refer to a system of a star, it refers specifically to the system that contains Earth. The star our system orbits is called "sol", hence "solar system." This can't be explained by saying a character simply chose to refer to another star system as a solar system, because solar system is a proper name. It would be like saying "China is a country on the Africa of Asia", when you mean to say "China is a country on the continent of Asia." This is a common mistake in many science fiction films, but is one that Star Trek rarely makes.
