In terms of moisture, there are no problems (you have the air gap outside), but the question is whether cc60 is sufficient or if the panel should be on, for example, cc30? If so, you may need to kortla.
The direction might be tricky too? I assume that cc60 on the studs is vertical? If the panel is to be mounted vertically, it becomes a bit tricky then - otherwise, it's easier
