Solar Panel Performance vs Sun Elevation
There are many factors that affect panel performance but one that is predictable is the angle of the sun striking the panel. The literature suggests that the panel watts * sin(sun angle on the panel) ...

Flexible panels are not as efficient. To get the same wattage, you need about 20% more surface area. RV roofs have a limited usable roof surface area.
An interesting point. How did you come up with the 20%? I did not experience this heat effect with my mppt controller ...
We are going in circles. Amorphous panels (this includes flexible) have less nominal wattage per square foot. Compare the dimensions and see for yourself. Don has already provided these numbers few posts earlier. I didn't calculate how many % less, but they ARE less efficient per square foot.
Heat dissipation (a problem with flexible panel) is a different matter.
