[RE-wrenches] Ballasted Roof Racking Recommendations?

There is a similar balasted rack from a company 
called 
Ecolibrium. 
http://www.triplepundit.com/2012/07/ecolibrium-solar-cutting-edge-simplicity-pv-solar-installation/. 


The fly in the ointment is that if the roof is 
not totally flat, the modules flex along the rows 
to make up the difference.  The company 
representative seems to think that this is just fine. What do you think?
