A pool cover is essential to keeping your pool free from dirt and debris. A solar pool cover adds to this function by helping to keep your pool warmer.

This cover is designed to raise the temperatures of the water below by a few degrees, which makes it more comfortable to swim especially in cold weather.

Additionally, it acts as an insulator that prevents heat loss in case you use a pool heater. This helps to reduce the overall running costs. That said, this article looks at the best solar pool covers that you should consider buying.

What to Check Before Buying Best Solar Pool Cover?

How to Buy the Best Solar Pool Cover

1. Type of Solar Pool Cover

There are 3 main types of solar pool covers to consider. These are:

Solar Blanket

This is the most common type of solar pool cover, and it is largely made up of thermal bubbles, which capture and retain the heat in your pool’s water. Apart from this, the blanket also reduces evaporation by up to 95% while also heating the pool by about 15°F.

Solar Ring

Solar rings also help to reduce water loss via evaporation but unlike solar blankets, this type features UV-resistant vinyl layers in rings, which are responsible for heating your pool.

Liquid Solar Cover

Liquid solar covers are very convenient because they are easy to apply, can be applied to a pool of any size, and you can use the pool while the cover is on. On evaporation, they reduce water loss by up to 40%.

Buying Guide: Each of these types has its benefits. If you want to conserve as much water as possible, then a blanket like Blue Wave’s NS520 is your best option.

Rings are easier to install because of their small size, but liquid covers are the easiest to apply since you only pour it in the water directly and that’s it.

2. Types of Pool

There are two main types of pools: above-ground and in-ground pools. For these types, there are solar pool covers that are meant for each one, and this should be considered before buying so that you get a product meant for your pool type.

However, there are universal pool covers, which can be used in either type of pool, and still works as efficiently as the specialized ones. These are highly recommended and the ideal one is Splash Pools’ SCV 18.

3. Size and Shape

This is a no-brainer. Obviously, you will need a size that fits or, in the case of blankets, one that is slightly larger so that you can trim it to fit. Therefore, ensure that you have your pool’s dimensions before ordering a pool cover.

For shape, this also mostly applies to blankets because the other 2 types can be used in all kinds of pools. With blankets, ensure that you buy a cover that matches your pool shape so that it fits.

4. Thickness

Measured in mils, blanket covers usually range from 6 to 16 mils in thickness, with the smaller value being thinner than the larger value.

The thicker the pool cover, the more heat it will retain and the longer it will retain that heat.

Thick covers such as Blue Wave’s NS520 are also less likely to be blown away by strong winds, but they are harder to roll and unroll and are definitely more expensive than thinner models. The choice is yours to make.

5. Material

Considering bubble/ blanket covers, this type is usually made of polymers, which can degrade easily under constant exposure to the sun’s rays and chemicals in the water.

If you are looking for a durable cover, you should look for the one that has a UV stabilized polymer or resin construction like Blue Wave’s NS110.

Such material is made to withstand exposure to the sun and water chemicals in the pool, and this will give you a longer service life.

  • Thickness: 8 mil
  • Shape: Circular
  • Color: Blue

Intex’s Easy Set and Frame Pool cover is the most affordable product in this review, but this does not make it substandard. It has the same small bubble design as the rectangular product above, but it is circular and is meant for above-ground circular pools.

In terms of dimensions, this piece measures 11 feet, 5 inches in diameter, making it suitable for 12-foot diameter above ground pools. Apart from this size, a smaller, cheaper size is available for a 10-foot pool. Larger, more costly ones also exist for 15, 16, and 18-foot diameter pools.

On color, although the unit’s blue finish may not be as fast as clear covers when heating, it gives your pool’s surface a very appealing look.

In addition to looks, this cover reduces water loss through evaporation by up to 95% and also retains heat inside for more comfortable swimming.

When not in use, a reusable carry bag (which it comes with) can be used to keep it safely in storage, and also makes it easier to transport the blanket from place to place.

Another important feature is its drain holes, which are designed to prevent water accumulation above the cover, which would otherwise minimize its effectiveness.


  • Affordable
  • Bubble design for heat capturing
  • Available in 5 different sizes for differently-sized above ground pools
  • Comes with a reusable carry bag for safekeeping and easy transportation
  • Drain holes for preventing water accumulation above

  • Thickness: 14 mil
  • Shape: Rectangular
  • Color: Clear

Blue Wave’s Solar Cover is a high-energy conserving rectangular pool blanket because it has a thickness of 14 mils, which means that it creates a thicker heat shield above the water to lock in most of the heat.

The blanket also features insulating thermal bubbles, which keep the heat sealed in and trap in the sun’s rays, converting them to heat in the process. This ensures that your pool remains warm through cold nights and overcast days.

Another factor that makes it a better heater is its clear color. This ensures that the maximum amount of light penetrates through for maximum heat absorption, with the capability of raising the temperature by up to 15°F.

On durability, the product is stabilized to handle the deterioration caused by UV rays and water chemicals, giving it longer service life.

In addition to this, the cover comes with a 6-year warranty, and therefore, if it deteriorates or gets damaged due to such causes, you can get a replacement or a refund.

On the downside, this unit is relatively expensive, but it comes in different sizes, ranging from a more affordable 12 × 24-foot size to a larger and more expensive 30 × 50-foot blanket.


  • 14 mils thick for better heat retention
  • Thermal bubbles for trapping heat
  • Clear color for maximum light penetration
  • Stabilized against UV and chemical degradation
  • Comes in different sizes for differently-sized in-ground pools


  • Relatively expensive
  • Does not come with a reusable carry bag

3. Harris H1632RTBB12 – Best Blue Solar Pool Cover

  • Thickness: 12 mil
  • Shape: Rectangular
  • Color: Blue

Harris’ rectangle solar pool cover is one of the best blue solar blankets because it is designed to maintain flexibility despite being exposed to UV light from the sun. Unlike other dark ones, which might become brittle after absorbing this light, this makes it very durable.

Apart from this, the 12-mils cover is also designed to give fantastic heat retention by acting as a heat shield, while also utilizing its thermal bubbles to capture the sun’s rays and using them to raise the temperature of the pool by up to 15°F.

Although not as fast as a clear cover in terms of heating, the blue finish gives a very appealing look to your pool.

On size, this one measures 16 × 32 feet, but there are other options, which range from a 12 × 18-foot size to a 20 × 40-foot cover. This gives you plenty of options to use for differently-sized inground pools.    

However, this blanket is relatively heavy and thus, it might be a little difficult to handle, especially if doing the installation alone.


  • Designed to handle the sun’s UV rays
  • Thermal bubbles for heat retention
  • Gives an appealing blue finish to your pool
  • Available in different sizes


  • A bit heavy
  • No clear-color option

  • Thickness: 12 mil
  • Shape: Rectangular
  • Color: Blue

In the Swim’s rectangle, the solar pool cover is one of the best in-ground pool blankets because it combines a number of very key features.

For starters, the 12-mils blanket is made of a UV stabilized resin, which makes it resist degrading from contact with chemicals and the sun’s UV rays.  

Heating is done using thousands of tiny air bubbles, which capture the heat and UV rays, then transfer all these as heat to the water below.

At the same time, the cover also prevents heat loss, water loss through evaporation, and chemical loss, leading to cheaper running costs.

On size, this product comes in a variety of them, ranging from a 12 × 20-foot rectangle to a 30 × 60-foot size for large pools. However, it can be trimmed to customize the shape for irregularly shaped pools such as oval or kidney-shaped ones.
