The best solar pool covers in 2026
A solar pool cover is a sheet of UV-stabilized bubble plastic that floats on the water's surface, using thousands of small air pockets to capture sunlight and transfer that heat into the pool while slowing evaporation overnight. Covering a pool when it is not in use can cut water loss noticeably and reduce how often a heater or chemicals need topping up, which is why solar covers pay for themselves fastest on pools that see regular sun. The Sun2Solar Blue 18 ft Round cover fits the most common size of round above-ground pool and comes in a 12 mil thickness that stands up to repeated folding and unfolding better than thinner blankets. Owners of rectangular or oval pools, or anyone with a pool larger than 18 feet across, should size up or switch shapes rather than trim a round cover to fit, since a cover cut too small will not seal in heat effectively.

Sun2Solar Blue 18 ft Round Pool Solar Cover
Sun2Solar Blue 18 ft Round Pool Solar Cover
This 1200 series cover uses a 12 mil bubble layer, thicker than Sun2Solar's entry-level 800 series, which helps it survive seasonal folding and storage without the bubbles collapsing. The 18 ft round cut matches one of the most widely sold above-ground pool sizes, so many owners can use it without any trimming. Its blue tint blocks more visible light than clear covers, which some owners prefer for slowing algae growth alongside the heat retention benefit.
Pros
- 12 mil thickness holds up to repeated use
- Fits a common 18 ft round pool size with no trimming
- Blue tint helps limit light reaching the water
Cons
- Heavier and bulkier to remove than thinner covers
- Still needs a reel or careful folding for storage
Blue Wave 16x32 ft Rectangle Solar Pool Cover
Blue Wave 16x32 ft Rectangle Solar Pool Cover
Rectangular above-ground pools need a cover cut to match their shape, and this Blue Wave cover is sized for a 16 by 32 ft footprint. Its 12 mil thermal bubble layer works the same way as the round Sun2Solar covers, floating directly on the surface to capture heat during the day and slow it from escaping at night. Blue Wave has manufactured pool covers for more than three decades, and the company backs this cover with a 5 year limited warranty.
Blue Wave NS110 18 ft Round Solar Blanket
Blue Wave NS110 18 ft Round Solar Blanket
The NS110 uses an 8 mil bubble layer rather than the thicker 12 mil found on premium covers, which keeps the price down while still delivering a stated temperature increase of up to 15 degrees Fahrenheit under good sun exposure. It suits owners who replace their solar cover every season or two rather than looking for the longest possible lifespan, or anyone testing whether a solar cover suits their routine before investing in a heavier one.
Sun2Solar Solar Cover Reel System
Sun2Solar Solar Cover Reel System
A solar cover only helps when it is actually on the pool, and a reel system turns covering and uncovering into a one-person job instead of a wrestling match with a sheet of wet plastic. This reel fits round or oval above-ground pools up to 24 ft wide without decking, and a simple hand crank winds the cover on evenly so it stores compactly at the pool's edge between uses.
Sun2Solar Blue 24 ft Round Pool Solar Cover
Sun2Solar Blue 24 ft Round Pool Solar Cover
Larger backyard pools lose more water to evaporation simply because they have more surface area, which makes a properly sized cover even more valuable. This 24 ft round cover uses the same 12 mil 1200 series construction as the smaller 18 ft version, so large pool owners get the same durability and heat retention scaled up to fit their pool without needing to join two smaller covers together.
How to choose a solar pool cover
Measure the pool's actual water surface rather than its outer frame before ordering, since solar covers are sold by nominal size and a cover that is slightly oversized is easier to trim than one that comes up short. Thickness matters more than most buyers expect: an 8 mil cover costs less upfront but tends to need replacing sooner than a 12 mil cover, so factor replacement frequency into the real cost of ownership. Finally, consider a reel system early rather than after a season of struggling to fold a wet cover by hand, since the extra convenience often determines whether a household actually covers the pool consistently.

FAQ
How much heat can a solar pool cover actually add?
Manufacturers commonly cite increases of up to about 15 degrees Fahrenheit under strong, consistent sun exposure, though real results depend on climate, how many hours of direct sun the pool gets, and how consistently the cover is used when the pool is not occupied.
Do solar covers really cut evaporation?
Yes. By sealing most of the water's surface, a solar cover blocks the airflow and open exposure that drive evaporation, and manufacturers report reductions of up to roughly 95 percent when the cover is used consistently, which also reduces how often chemicals need to be replenished.
What is the difference between 8 mil and 12 mil covers?
The number refers to the thickness of the plastic sheeting in thousandths of an inch. Thicker 12 mil covers resist punctures and repeated folding better and tend to last longer, while thinner 8 mil covers cost less but typically need replacing sooner.
Do I need a reel system with a solar cover?
A reel is not required, but it makes daily use far easier, especially for larger pools where folding a wet cover by hand is awkward. Households that skip a reel often end up leaving the cover off more often simply because putting it on is inconvenient.
