The thing I'd worry about with TPO on the sides is gravity. On the roof, gravity is continuously working for you. On the sides, it is working against you 24/7/352. On the roof or on the sides, there will be occasional 60+ MPH headwinds, when driving. You would have to have a good deal of faith in the glue on the sides, never to fail during the life of the application. For that reason, I might be inclined to favour something with fasteners.
Actually, I did see that Carlisle (manufacturer of the TPO I have), does make an adhesive for vertical installation, instead of the normal flat, horizontal installation.
Obviously, I would not be the first one to do that.
I'll have to look a little closer into that before making a decision.
