Factors to Consider When Choosing an Above Ground Pool Solar Cover
As you choose an above ground pool solar cover, start by matching it to your pool’s shape and size so it fits properly. You should also compare material thickness, heat retention performance, and how well it reduces evaporation. A good cover should be easy to install and stay secure while it works.
Pool Shape And Size
Choosing the right solar cover starts with your pool’s shape and size. Measure the outer diameter of a round pool, or the length and width of a rectangular or oval pool, then pick a cover that is at least that large, or slightly bigger, so it overlaps cleanly and attaches easily. Match the cover to the pool’s outline so you are not dealing with awkward edges or gaps. If your pool has steel frames, ladders, or rails, leave extra room or trim carefully so the cover clears the hardware without pulling tight. For attached spas, built-in steps, or unusual contours, choose a trim-to-fit or custom cover. If you use a reel, make sure the cover fits its width and rolls smoothly without excess folding.
Material Thickness
Once you have matched the cover to your pool’s shape and size, the next choice is thickness. You will usually see 6 to 8 mil films and heavier 12 mil plus options. Thicker covers hold up better against UV exposure, repeated folding, and rough handling, so they are a smarter choice if you want longer service life. They also resist wind, punctures, and seam stress more effectively, especially during storms or when you drag them over sharp edges. The trade off is weight. Thicker material can be harder to install, remove, and store, and it may cost more upfront. If you are balancing budget, convenience, and durability, choose the lightest cover that still meets your longevity needs.
Heat Retention Performance
Heat retention is where a solar cover really proves its value. You will get the best results when you choose a thicker, denser cover, because it insulates better and can raise your water temperature by as much as 15°F in strong sun. Look for thermal bubble designs, since they trap air against the pool surface and slow heat loss overnight and on cloudy days. You should also check the bubble orientation and color. Transparent or light-colored bubbles facing down can still let solar energy through while holding warmth. A proper fit matters too. When the cover closely matches your pool’s shape and overlap, it leaves less exposed water, so heat stays in the pool longer. Strong heat retention also helps your water hold the gains you have already earned.
Evaporation Reduction
Beyond holding heat, a good above ground pool solar cover also reduces water loss by limiting evaporation. The best covers can cut evaporation by about 75% to 95%, especially when you choose thicker, bubble insulated models. A continuous floating barrier works best because gaps and exposed edges allow moisture to escape. Look for multi mil film and dense thermal bubbles, since they hold surface moisture better than thin, low density materials. UV resistant coatings matter too, because sunlight can weaken the cover and reduce sealing performance over time. You should also choose a cover with secure attachment features, such as overlap, drawstrings, or fasteners, to limit wind uplift and edge evaporation. That way, you preserve more water during hot, breezy weather.
Fit And Installation
To get the right fit, measure your pool’s outer diameter, including any lip or frame, and choose a solar cover that matches it or is slightly larger for full overlap. That extra edge helps the cover seal and stay in place.
Next, match the installation style to how you plan to use it. A floating cover works for simple daily use, while reel compatible models make removal easier. If you prefer a snug setup, look for buckle or drawstring designs.
For steel frame or irregular pools, pick a trim to fit option or add extra material so you do not create tension points that can tear. In windy areas, choose grommets, straps, or anchors. Finally, check the cover’s weight, thickness, and handle placement so you can install and store it safely.
Frequently Asked Questions
How Do I Cut a Solar Cover to Fit Odd-Shaped Pools?
Think of it like tailoring a swimsuit. Lay the cover over your pool, trace the shape with a marker, then trim slowly with sharp scissors, leaving a small overlap so you can fine tune the fit later.
Can Solar Covers Reduce Pool Chemical Use Significantly?
Yes, you can reduce chemical use noticeably because a solar cover limits evaporation, sunlight, and debris. You will still need balanced testing and occasional treatment, but you will likely use less chlorine and make fewer adjustments overall.
How Often Should I Replace a Pool Solar Cover?
You’ll usually replace your pool solar cover every 3 to 5 years, or sooner if it becomes brittle or faded. The sun that saves energy also breaks down the cover over time. Inspect it yearly and replace it when it no longer holds heat well.
Do Solar Covers Work With Automatic Pool Cleaners?
Yes, you can use solar covers with automatic pool cleaners, but you will usually need to remove the cover first. The cleaner cannot move properly underneath it, and the cover may snag or wear out faster.
Can I Use a Solar Cover During Heavy Rain or Storms?
No, you should not use one during heavy rain or storms. It can act like a sail and cause damage. For better protection, remove it, secure any pool gear, and wait out the weather safely.
