I suggest you forget the whole thing. Your allergy is the controlling issue.
As far as DIY...if you allergy is that bad, don't even try it.
If you have a pro do it, they should be able to rough the surface up and epoxy mounts to the outside surface. This process doesn't need to go through the roof.
You still need to get the cabling down to the batteries and an openable window doesn't make sense. It's going to be very inconvenient to climb up on the roof every time you want to connect it. The big advantage of solar is you install it and it just works.
