It means the sun, but it doesn't stand alone well.

What a Japanese person actually thinks
Most readers will take it as a name — it's a very common element in given names — before they take it as a statement.

Meaning

Literally: sun; the yang principle
Actually: The sun or the yang half of yin-yang — but in modern Japanese it lives inside compounds (太陽 the sun, 陽気 cheerful). Alone it reads as a fragment.
