Look at Cover Pools. They have an option for an on-deck automatic cover. They are not cheap, however. I strongly advise you find an authorized/certified installer to have it installed (don't take the installer's word for it - inquire with the manufacturer), as a bad installation will ruin the cover - ours did! If your deck around the pool is concrete you should have no issues with this type of on-deck cover. If the deck is interlock/pavers, more prep work may need to be done for the track installation, as the stones may sag/settle, taking the track down with them, or leaving no support for the track.

There are great advantages of having these covers - they function as safety, solar and winter covers all-in-one - we had ours installed because we had small kids at the time and wanted the safety, but soon discovered the other pluses. For example, every spring when we opened our pool it was just a matter of vacuuming and adding chlorine, the water was never murky or green. Now this may be because of other reasons as well, not sure, but we've always heard stories from others of having to muck around with chemicals for weeks after the pool opening. My suspicion is that it was due to the fact that the cover did not allow rain/snow to get into the pool over the fall/winter.
