Hey will...since you're in a holding pattern, and the solar cover topic came up, thought I'd share my experience with them over the years. Our last house was in a similar environment to Las Vegas...high desert. It was about 6 degrees cooler on average, but the nights cooled a bit more as it was closer to the coast. We also had a lot more afternoon wind to go along with the cooler evening temps. So, we did get a lot of junk on top of the covers. We had crusty junk from water evaporation and blown in plant matter and the occasional plastic bag or paper. Naturally , taking it off would inevitably result in some of this being dumped into the pool.
Then there is also what happens when the plastic eventually deteriorates, and the bubbles start rotting off. Guess where they go? (Hint, if you said "the trash can", you are a new pool owner..LOL

) Yeah, the bottom of the pool is right! And guess how many trash cans it takes to throw away a cover? They will definitely all need disposal at some point. And if they fill up a trash can or three, how much room do you think they need when you take them off to go swimming? And being light plastic, you wouldn't think they'd blow around in that 20 mph sustained afternoon wind do you? And of course, that blob of plastic makes a fantastic accent to your lush, tropical back yard too...

That is, once you're done wrangling it off the pool, in the aforementioned wind, because it won't act like a sail or anything.
But the worst part was that at some point we would get busy, take a vacation or something in the middle of summer, and look at the pool in horror, as it had turned green due to using up all the chlorine in the pool, and reaching over 100 degrees. This happened about once a summer, and we finally just said it wasn't worth it.
Now that we have the "bad" out of the way, there is some definite "good" with them. Namely, they do work to heat/keep the water warm in our climate. They also keep the evaporation down from heat and wind. And if like me, you have a wife who prefers water about the temperature of a hot cup of coffee, often times a little bit of good far outweighs a lot of bad. And couple that with the ingenuity of the smart people here on TFP, and I'm determined to give it one more go..
I'm going to try the build it yourself roller gizmo idea from the forum, and make mine in about 3 or 4 pieces. This seems like a great way to solve the on and off problem, as well as the appearance issue. I think with the SWG, I might be able to avoid the attack of the green swamp monster (you DO hear my wife laughing, it's not your imagination!) I figure if I cut them into pieces when they are new, it will make it much easier, and less messy, to cut them in pieces to throw them away every couple years to try and avoid the invasion of the plastic bubble pieces. Plus, the local water agency has a coupon that you can save 50% on a cover, so I figure it'll only cost me half as much to remember the other reasons we gave up on them (even without a heater of any kind!).
And I do have a wife approved back up plan should we continue to have a fun-filled, keystone cops level adventure with solar covers in our back yard: just use the dang heater! (she's always right, but one day I will accidentally prove her wrong! LOL)
