Solar Panel Cover Reel

New owner of 21' AGP with question about putting on and taking off Solar Panel Cover.

What is the best system to consider? I have research the Solar Panel Cover Reels that seem to make it easy but they get mixed reviews. Another attaches U-shaped holders to put the Panel Cover in but it seems burdensome.

So what is the best answer?

Thanks in advance.

I'm not aware of a really good solution; all the experiences I've heard of (or had myself) are quite mixed. I've seen and used very expensive all stainless roller systems, and they are also a pain.

To some degree, solar covers are just a pain you have to live with, if you want to use one.
