[Greenbuilding] Clamp Solar Collectors to Standing Seam Roofs

[Keith Winston]

That is the  most common way to attach to a standing seam roof. Do you 
have evacuated tubes or flat-plates? Are you angling them off the roof, 
or will they be flat to it? How close? All those considerations will 
strongly effect wind shear, which is probably the only thing (well, 
snowload in certain situations) that might develop enough force to cause 
problems.

I suppose there would at least be a sideways force that the roof would not normally be subject to.  Anyone have any thoughts on this?  How have you attached solar collectors to standing seam roofs, and was it successful?
