10 Best Pool Solar Covers 2025 in the United States

The BigXwell Solar Pool Cover is designed for in-ground pools with a size of 12 x 24 feet and a thickness of 16 mil. This heavy-duty cover effectively harnesses the sun’s energy using its bubble design, trapping heat to keep your pool warm. This feature is particularly beneficial for those looking to enjoy swimming without relying heavily on traditional heaters, especially on cloudy days or during chilly nights.

One of the standout strengths is its ability to prevent water and chemical evaporation, which can reduce water loss by up to 95%. This not only keeps the pool cleaner by blocking out debris and leaves but also cuts down on maintenance costs, making it a great option for pool owners who want to save time and money.

However, there are a few drawbacks to consider. Although the cover is lightweight and easy to install, some users might find it challenging to handle due to its size, especially when removing or storing it. Additionally, while the material is made of polyethylene, which is durable, the longevity of its performance can vary in extreme weather conditions. In terms of color, the blue shade is visually appealing and fits well in most outdoor settings, but some may prefer different color options for aesthetic reasons.

The SunHeater Pool Solar Blanket is designed to effectively heat your pool while minimizing water evaporation, making it a solid choice for pool owners. One of its standout features is its ability to trap heat from the sun, which can significantly raise the temperature of your pool water. With a durable 12 mil thick polyethylene material, this cover promises longevity and resilience against wear and tear, ensuring it can withstand the elements for repeated seasonal use.

In terms of usability, the cover measures 16 feet by 32 feet, making it suitable for larger rectangular in-ground and above-ground pools. It can be trimmed to fit various shapes, such as square or round pools, which adds a level of customization that many other covers may lack. Additionally, it excels at reducing water loss by up to 95%, which not only saves water but also cuts down on maintenance costs due to reduced cleaning time from debris.

There are a few drawbacks to consider. While the cover's heavy-duty construction is a plus, it also makes it somewhat cumbersome to handle, weighing around 31 pounds. This weight may pose challenges when putting it on or taking it off the pool, especially for individuals who may struggle with lifting heavier items. Furthermore, while the bubble design effectively traps warmth, it may require regular maintenance to ensure that the bubbles remain in good condition and do not become damaged over time.

The 'In The Swim 18' x 36' Standard Blue Rectangle Solar Pool Cover' is designed to enhance your swimming pool experience by increasing the surface water temperature up to 10 degrees, which can help extend your pool season. Made from polyethylene, it has an 8 Mil thickness, which contributes to its heat retention capabilities. The light blue color strikes a balance between absorbing heat from the sun and retaining it, making it effective for heating above-ground and in-ground pools. The cover also helps in preventing evaporative heat loss during cooler nights, which is a bonus for maintaining consistent water temperature.

Its rectangular shape and large size (18' x 36') make it suitable for a variety of pool types, but be mindful that it is relatively heavy at 32 pounds, which might be cumbersome for some users to handle without a reel. The product's bubble design contributes to its effectiveness as a heat insulator, but the cover should only be used when chlorine levels are below 2.5 ppm and pH levels above 7.2 to prevent damage. Proper maintenance and handling are essential as per the manufacturer's instructions. Using a solar cover reel can make the process more convenient and help reduce wear and tear.

While it performs well in its heating function and extends pool usability, the cover's weight and the requirement for specific chemical levels in the pool water could be potential drawbacks for some users.
