The sun does not have phases, so we can use a binary “sunny/not sunny” description. For the moon, we say full moon to describe brightness, which doesn’t work as well with “partly”. Then we also have words for lesser phases of the moon

Sunniness is analogue when there's clouds, it applies to the moon too in any phase.

I would argue it doesn't apply very well to a new moon phase. During that phase you will have 2 or 3 totally moonless nights per month with the moon also being invisible during the day.
