Solar is a good person instead of being the antagonist that most other universe Eclipse's are. He's helpful and caring, and he doesn't understand why the other Eclipse's mistreat Lunar. He did all of the work in maintaining and running the Daycare in his dimension too, as his Moon didn't care to do any of the work himself and just focused on trying to repair Sun. But after his Moon failed to fix his Sun, he threatened to rip Solar apart for parts, so he had to flee the main dimension.
