Thin enough to roll suggests it would be lighter weight which should make it easier and cheaper to install, especially on a rooftop. They would still need solid mounts if they are raised above a household roof, but like the difference between mounts for old and heavy CRTs and today's lightweight flat-screens.

It also means that there are possibilities for simply mounting it on walls and other surfaces that currently aren't options because of the weight of panels or the need to align them just right to recoup the cost.
