Greg...
The typical stanchion is PRIMARILY designed to resist gravity.
I'm of the opinion that very, very, few are designed to combat sail effect.
Further, as you know from Florida's 'wind issue' that the WHOLE dang roof may do a 'Dorothy' if not tied down.
These are issues that are very hard to deal with -- after the dang house is old work.
I can see massive lawsuits, just around the corner, that will wipe out 'solar electric' players. Kind of like the move against aluminum siding. -- See "Tin Men" -- funny as all get out, BTW.
