Why you can trust Top Ten Reviews Our expert reviewers spend hours testing and comparing products and services so you can choose the best for you. Find out more about how we test.
The best round solar pool cover
The In The Swim Premium 12 Mil Solar Blanket is made of polyethylene. Its thick material can raise the temperature of your pool by up to 15 degrees Fahrenheit, which can really help cut heating costs.
Raised air pockets on the surface of this thick blanket prevent your pool water from evaporating and protect it from things like falling tree branches or garbage - not to mention small, unwanted insect visitors. The air bubbles also trap heat and keep your pool warm. The thickness of this solar blanket means it’s pretty durable, but the real winner is the impressive seven-year warranty that gives you added peace of mind.
This solar pool cover also has UV-stabilized resin to prevent excess sun damage. If your pool isn’t round, that’s not an issue, as you can cut this pool cover to size.
While there aren’t many reviews for the In The Swim 12 Mil Solar Pool Blanket, it scores an average of 4.5 out of five stars on the company’s website. Users state that it effectively warms the water.
The best solar pool cover for in-ground pools
The Sun2Solar 1200 Series Solar Pool Cover is oval and ideal for both in-ground and above-ground swimming pools. You can cut it to suit your pool, and this won't affect your warranty.
The small air pockets on the underside of the blanket capture and send solar heat back into your pool's water, keeping it warm even on cloudy days. You can choose a blue or clear blanket; however, we recommend the clear version as sunlight can travel directly into the water.
It is, however, one of the most expensive solar pool covers that we’ve reviewed, so there are cheaper alternatives available. Regarding user ratings, this Sun2Solar pool cover scores an average of 4.5 stars out of five on Amazon. Users who rate the solar pool cover highly comment on how they find it to be ‘strong enough that it won’t tear.’ Others also found it to be durable and thick. Some users reported the bubbles began to come away after a couple of years of use.
The easiest to remove solar pool cover
Featuring small bubbles that insulate your swimming pool, the Blue Wave NS120 is a solar pool blanket that can improve the temperature of your pool by up to 15 degrees Fahrenheit.
As a result of being left in direct sunlight, a solar pool cover must be made to be resistant to the wear and tear from UV radiation, along with the chemicals that you treat your pool water with. This is one of the pricier options in our round-up. However, you do get a three-year warranty, which provides peace of mind that your investment purchase will last.
This solar pool cover is round, so it won't be suitable for square pools. It has been designed for above-ground swimming pools. It does, however, claim to prevent 'up to 95% of pool water and chemical evaporation', so you won't have to worry about spending time or money replenishing it.
With an average rating of 3.7 out of five stars on Amazon, it's a solid choice. Users who loved the Blue Wave NS120 cover stated that it 'raised the water temp over 20 degrees in a week'. Others mentioned that it was easy to take off the pool and very durable. Some negative reviews said the cover is 'thin,' and some customers had issues with the bubbles popping and disintegrating.
The best lightweight solar pool cover
Are you fed up with jumping into a cold pool? The Thermo-Tex Pool Cover aims to make your pool a more pleasant temperature in all seasons. It's made from UV-stabilized polymers, so you can rest assured that the high quality will stand the test of time and withstand the elements. This will also protect your pool for longer and any negative effects your pool chemicals may have.
The lightweight design of this cover makes gaining access to the water much easier, so it's a great option for those who use their pool often. If you find yourself covering your pool solo, it will also make maneuvering it safer and smoother.
Reviews are overwhelmingly positive about this Thermo-Text cover, with many commenting on the noticeable difference it makes to their pool temperatures. One reviewer also mentioned that this cover has helped to prevent algae growth as less water evaporates within their pool. The three-year manufacturer's limited warranty also provides added peace of mind.
The best portable solar pool cover
The Intex Recreation 29025E is a vinyl solar pool cover, making it lightweight and easy to store, transport, and attach. It comes with a carry case, so you can move it to a garage or storage area with minimal effort.
Air bubbles absorb and transfer sun heat into the pool water, resulting in a warmer water temperature that is much more pleasant to jump into. This cover reduces water evaporation by 95%, minimizing heat loss and how often you need to fill up the pool—better for your water bills and the environment. This cover will also keep debris out of your pool, so less upkeep is required when it comes to cleaning.
It's 18ft and comes in a round design, making it a great choice for pools of the same shape and size. Reviews mention a downside being that it doesn't attach to the frame of the pool, inside just suctioning to the water itself, however there are no bad reviews mentioning that it lifts off or moves.
How to choose the best solar pool cover for you
The bare minimum your solar pool cover should do is keep your pool’s temperature from severely dropping by retaining the sun’s heat. Thickness and insulation are also essential so that less water evaporation occurs inside the pool. You also want a cover that will keep the direct sunlight from draining the chemicals that are working to clean your pool, as you’ll have to top those up more, if not, and run the risk of algae growing in their absence.
Safety should be another crucial concern when looking for a pool cover. Options that are easy to put on correctly will prevent you from accidentally leaving your pool unprotected and, importantly, keep your pets and loved ones safe. Make sure that if your child or an animal were to step on top of your cover accidentally, it would be able to support their weight.
Thickness is the last factor to think about on your buying journey. While a thicker cover will do a better job retaining heat, these tend to be more expensive and more of a task to take on and off.
Solar pool cover FAQs
How does a solar pool cover work?
Solar pool covers take the sun's heat and transfer it to your pool's water. They do that by having lots of air pockets, and those pockets work rather like little greenhouses: the air inside them gets heated by the sun, and they're designed to retain and transmit that heat to the water below them.
In addition to their warming effect, which can sometimes increase your water temperature by double figures, they act like normal pool covers and keep the heat in. Without a cover, the heat from your pool water will escape upwards, but by covering it, you can massively slow down that process so that your water is nice and toasty when it's time to go for a dip.
How fast does a solar cover heat a pool?
That depends on the size of your pool and the sun's heat, but as a rule of thumb, the peak heating effect will take roughly six hours in high summer when the sun is hot, and your pool isn't in the shade.
Can you run a pool pump with a solar cover on?
Yes, you can. And you should because you'll be speeding up the heating process and reducing heat loss in the air. There's another benefit, too, which is that by keeping the pool covered while it heats, you're preventing things such as leaves from blowing onto it.
Which way up does a solar pool cover go?
You should place your solar pool cover with its bubbles facing downwards. That means the air inside the bubbles is closer to the water, so you'll get the maximum benefit from its retained heat.
Are solar pool covers recyclable?
That depends very much on where you live (some places have better recycling facilities than others), the manufacturer, and the materials used, but many manufacturers make their covers from recyclable plastics.
If you're thinking green, it's also important to consider the lifespan of your solar pool cover. A super-cheap model might only last for a single season before needing to be replaced, so over a few years, its environmental footprint would be larger than that of a better-made model.
