Home PV systems are going to be no more resistant to high wind than anything else in the typical house, you're right. However it makes as much sense to build them in hurricane-prone areas as it does anything else, including a traditional above-ground grid with transformers and suspended transmission lines.

Actually, the installation of of solar PV makes very good sense from the point of view of reducing GHG emissions and mitigating global warming--which in the longer run might reduce the severity and frequency of storms too.

In fact, in a sunbelt area that has lost most of its traditional grid, and much of its housing, it makes PERFECT sense to rebuild with PV since everything has to be rebuilt anyhow. 

My experience in Katrina however, suggests that it won't happen. The grid and the housing will be rebuilt to be almost exactly the same as it was before; wasteful, vulnerable and extremely profitable to the utility that provides the juice.
