Bwise.,
I am not sure how this work out but one way you can find out is take a single panel and do the short circuit of that panel to see how much it will produce and I am aware the solar panels are not a infine source so it may get by with lower rating but the best answer is check with the manufacter of that solar panel they should able give you some infomation what you are looking for.
And also most larger solar panels I have see they will have sectional fuses as well { some will use circuit breaker as well as long they are rated for DC useage.}
I know one of the guys in the fourm is inspecting the large solar panel maybe he can give you some infomation if he do know about it.
Merci,
Marc
