Don, not sure about Saskatchewan prairies but in Mexican Baja I can't even use my awning. If I do - on some calm day, there is 50% chance that I'll wake up in the night with awning all rattling, shaking and trying to lift off, and will have to fumble in the dark with this badly engineered thing.
I would imagine solar sail on a spacecraft but wouldn't want to have it on my little sail on the water. Most common sail material - Dacron - stretches. Not much, but still does. Now add the layer of solar microfilm on it and try sailing, hoisting/lowering, furling/unfurling, subjecting it to abrasion while on the passage and while taking it off and stowing.
The most relevant info for you is contained in the last paragraph of the article where they are talking about the prototype that "could be" used for furling sail systems and awnings.
