Where to mount solar panels on roof?

The new thin flexible panels do look nice. I sure thought about using them on my roof, but I read a couple concerns about if they could be glued to the roof.. heat buildup and some cupping in some of the early testers. I decided to stick with the traditional panels.

For me having them up on the roof working while driving down the road and basically being installed and forgot outweighed using any portable and worrying if they might walk away.

I do see where if you camp in heavy shade or want to chase the sun, a couple portable panels could work for you.
