Will a pool's solar cover be damaged if it is not covered after it is rolled up on the cover roller and left at the pool in the sun?

Generally, no, it won't be damaged. A solar pool cover is designed to withstand the sun and the weather. Leaving it out in the sun/weather on the cover roller WILL cause only the exposed section to see any wear. But serious damage will take a long time to happen. Hope this helps...

The top layer of the rolled up cover transfers heat etc through several layers deep each in turn burning the other. Covering the solar blanket reduces the damage somewhat. The "burning effect" is compounded and will eventually reach thru several layers all the way to the reel. The bubbles act like a magnifying glass. Not a good idea. k
