Our array is engineered for 110 mph and was solid, no issues. I built a ground mount to get that perfect orientation with twelve 12" wide concrete footings sunk 4-8 foot deep drilled into blue rock. Yes, overkill I know. Also put it on the leeward side of the house so the wind goes up and over the array.
I'm confident it could handle up to a 3 hurricane though. Anthing above a 3 hurricane the metal roof will be coming off the house anyway before the pv's go flying.
I think the best design is an array mounted on a carport with proper orientation. Build a large closet at the end for battery box, inverter and charge controller and then underground your wire to the house. Then you could also charge an electric car in the future if you wanted.
I believe in minimizing your holes in the roof of your home with so much rainfall here just like you minimize thru-hull fittings on a boat hull.
