Stick to Lance TPO roof?
I want to install ~140 watts of solar generation on the roof of my new Lance 850. I have determined that the wiring, and a suitable plug, are in place. I think. Anyway, there is a little cove...

I personally would not trust just gluing or taping them down. I used aluminum "L" brackets and I first applied butyl tape to the bottom of the bracket, then pushed the brackets down onto the roof. I then secured with several screws into the roof. The butyl caulk squeezed up thru the screw holes, so after tightening the screws down, I felt confident that the holes were sealed properly. I then encased the entire bracket base around all sides and over the screw heads with ample amount of Dicor. My panels have been on for 3 years and about 25K miles and so far they are still solid and trouble free.
I used a very similar process but used VHB tape instead. The professional grade VHB tape can be purchased through AM Solar.
