I think you need to do a trip up on the roof to take some measurements, ideally maybe even create some cardboard templates. Also need to watch for shadows, they may fit but but then they may be shadowed.
I fit 3 100W mono's on mine across the front 2 on 1 side and 1 on the other side of the non-centered fan.
I could fit another panel pretty easily but instead decided to add a 100W portable.
