Solar panels on the rail

Paul Osterberg
 

For you who have solar panels on the rail, which size do you have?
Currently we have 450 w on an Emek Arc, and 2x 100 watt on the rail, the 2x 100 are semi flexible works ok, but I can see that they degrade and will not last very long. Plan to install ridged panels on the rail instead. 100 watt readily available, in US next step looks as 160 watt but they looks a bit large size wise. hence the question from you with experience.
