These are going on the metal roof of an enclosed trailer, so I have more flexibility in mounting or removing compared to TPO, fiberglass or rubber surfaces.

In that case they may be good, but you may also have an issue if the roof is rounded. If you were parked N/S, half the panels would be tilted away from the sun, morning and evening. If parked E/W, half would be tilted away almost the entire day (in summer), and the entire day (in winter).
