7 Best Solar Pool Covers in [current_year] (Review)

The most demanding electrical consumption in any household is always related to heating. Using heaters for your indoor areas and also for heating water consumes a lot of electricity. Therefore, it has an important impact on your energy bill at the end of the month.

If you own a pool, then you probably like to have tempered water, but by installing a traditional pool heating system, you will spend a lot of money in equipment and installation — not to mention the increased energy costs that you will have to pay for every month. A simple and economical solution to this problem is to install a solar pool cover. Solar pool covers use the sun’s heat to keep water warm and save money on electricity. Furthermore, these pool covers can also be used as a protection to your pool which in combination with solar pool cleaners, will keep the water of your pool free from contamination and bacteria.

How to Choose a Solar Pool Cover – 3 Key Things to Make Sure Of

Size of your pool

One of the first details that you must look into when selecting swimming pool solar covers is related to the size and dimensions of the product. Here, you must also consider what is the shape of your pool. Typical configurations are rectangle, round, oval and kidney-shaped swimming pools.

According to the configuration, you must verify that the pool cover has been designed for your specific shape. Some pool covers will have a rectangular shape, but you may adjust or fit the bubble wrap to the size of the pool. The best way to measure this would be to check the size of your pool (if you don’t know it, you would need to go and measure with tape) and then calculate if that particular pool shape and size would be able to fit within the rectangle bubble wrap. For instance, a 15 ft solar pool cover may be used to fit a 10 ft round pool (depending on width), while a 10 ft solar pool cover may be too short to be trimmed. Keep in mind to always leave around 4” extra to trim the cover.

Keep in mind that the reference values for parameter sizing are:

Rectangle: Width x large

Round: Diameter

Oval: Minor axis x major axis

Kidney: Large, shallow end and the deep end


Another factor that must be considered is the color of the pool cover. Some pool covers are designed with a transparent layer that allows more light and energy to pass through the cover to the water, this means that the heat gain is higher and therefore, water gets warmer faster.

The bad side of a clear transparent cover is that it absorbs less heat, which means that the cover would not be able to maintain heat as much as a darker color cover would. Besides, since almost all UV radiation is allowed to pass through the cover, the chemical loss is higher and also customers say that clear covers are not as aesthetic as blue ones.

The other two options are a light blue or a dark blue solar pool cover. The light blue cover will do a better work trapping the heat inside and also keeping UV rays out (which reduces chemical losses), however, the downside is that it will block out some of the heat. Meanwhile, dark blue covers are the best ones to trap heat inside, but the heat gain can be as low as half when compared to clear solar blankets.

In a few words, a transparent cover is best for heat gain (warming water faster), while a dark blue cover is best for trapping heat inside. Finally, a light blue color solar blanket is probably the best balance between them.


Another useful parameter to consider is the thickness of the solar pool cover. Thickness can be usually found between 8 Mil, 12 Mil, 14 Mil and up to 16 Mil. When evaluating performance, a thinner solar blanket cover allows heat to pass through to the water more easily, however, it does not trap heat as efficiently. A thicker solar cover will trap heat more efficiently inside but will heat the pool at a slower rate than a clear one would. The trade-off between these two factors is usually a 12 Mil solar blanket, which is the one that most people use.

What are the Different Types of Solar Pool Blankets?

Solar pool blankets can be classified according to three categories.

The first category would be related to shape. In this aspect, there are rectangular, round, and oval shape covers. If you own a kidney shape cover, you will need to trim a rectangular solar blanket to fit the size of your pool.

The second category is related to color type. As we discussed in the section above, there are three color types: clear, light blue and dark blue.  The darker the color, the better it will be for heat retention, while the lighter, the better it will be for heat absorption. If you intend to use the blanket during the night, then it would be best to use a darker color one, while if you intend to use it during the day, then use a clear transparent one.

Finally, the third category is the type of pool that is designed for. It can either be for in-ground or above-ground pools.

How Much Warmer Will Your Swimming Pool Be?

the pool is covered

Average pool covers can raise the temperature up to 15 additional degrees Fahrenheit than what the temperature of the pool would be without the blanket. This is dependent on the solar radiation of your location and season. Using a clear solar blanket in a cloudy location will not raise temperature as efficiently and will not keep the water warm. In that case, using darker models may be better.

If you still want to raise temperature values with an eco-friendly solution, then combining solar pool covers with solar pool heaters is probably the most environmentally and economically attractive option.

How to Make Sure the Cover Doesn’t Get Damaged in Bad Weather

The solar cover is just a simple polymer material blanket designed to trap the heat of the sun inside the pool, so in bad weather conditions, you should take care of it. To get started, when the swimming season is over, simply remove and store the pool cover inside a cool temperature place which temperature does not exceed 120°F. Pool covers are not designed for low temperature and snow conditions during the winter season.

For the colder months, you will need a winter cover for the pool. Under bad weather conditions such as storms, you must remove the cover and store it in a dry but cool place. Among other maintenance considerations, keep in mind that when you remove the cover you need to avoid or remove any nearby sharp points. Also, the blanket is not designed to be placed under the sun for long periods of time without water beneath it, therefore is better that you place it under the shade when it’s not on the water.
