Now, to the question. If your panels are mounted correctly they should stay on your roof. If your roof stays attached to your house then you should be able to get power from them. Remember, many more people loose power than loose houses in these storms.

It makes sense to me to use inverters that will let you feed panel to your house system if the grid goes down. If you could run your refer/freezer a few hours a day direct off solar it should keep your food from spoiling for a while. And you could charge up flashlight/radio batteries.

Owning a battery bank just to take care of you after storms. That doesn’t make a lot of sense to me. When we get better batteries then having storage at the neighborhood level and smart grid switching does.

An alternative that I would suggest would be to create community owned systems rather than only relying on individuals. Protection of the system will still have to be addressed.
