I have had essentially the same mount as photohc for 2 solar cynergy 120W panels for 6 months now. I did away with the weld mounts though, and counter sunk the screws in the aluminium bar stock, and VHB taped the bar stock to the roof. No issues with the mounting system.
So far so good on the flexible panels - they are giving me about what they should for a flat mounted panel at this time of year - about 140W peak output, which is ~ 60% of their rating.
