Are you sure it isn't I<sub>n? That would denote I (current) n (nominal or normal). Basically that would just say that someone wants to know the current rating of the panel, but not based on the connected load, overload capability or short circuit current rating. Just "what is it rated for?".

I was posting from an iPad so no access to formatting.

In = Continuous current rating per IEC 60947-2
