10 Best Pool Solar Covers 2025 in the United States

The BigXwell Solar Pool Cover is designed to harness solar energy to heat your pool. Its 16-mil thickness and thermal bubble design are effective in trapping heat from the sun, which can warm up the pool during sunny days and maintain the temperature during cooler nights. The polyethylene material promises durability and longevity, even under harsh weather conditions, while also being lightweight and easy to install or remove.

The blue color of the cover not only looks appealing but also contributes to UV protection, which is crucial for minimizing water evaporation – claimed to be reduced by up to 95%, helping conserve water significantly. Additionally, the cover can be trimmed to fit pools of various shapes, making it versatile for both in-ground and above-ground pools.

However, at 50.9 pounds, it might be a bit heavy for some users to handle. Given its size of 16 x 32 feet, it is suitable for larger pools. This cover is a robust option for those looking to efficiently heat their pool and reduce water evaporation, with the flexibility of fitting different pool shapes and sizes.

The Sun2Solar Blue 20 ft x 40 ft Rectangle Solar Cover is designed for rectangular inground and above-ground pools, offering effective solar heating and protection. Made from durable resin material, this cover features a bubble design that traps heat efficiently, helping raise the pool temperature by up to 15 degrees and retaining warmth overnight. Its blue color is common for solar covers and helps with sunlight absorption. Sized to fit a 20 by 40-foot pool, it provides good coverage and includes extra overlap to fit around any pool protrusions.

The cover also significantly reduces water evaporation—up to 95%—which helps save water and lowers chemical use. It prevents leaves and debris from entering the pool, reducing cleaning efforts. While the cover is lightweight enough for easy installation and removal, it weighs about 40 pounds, which might require some care during handling. The material requires hand washing, so it needs gentle maintenance compared to more durable pool covers.

This product represents a solid choice for pool owners looking for an affordable way to keep water warm using free solar energy, especially if the pool size matches the cover dimensions. For those with non-rectangular pool shapes or who need a cover with enhanced durability or automatic features, it may be beneficial to consider other options.

The VEVOR Solar Pool Cover is a 40 x 20 feet rectangular blanket made from durable 16 mil thick polyethylene material, which makes it strong and resistant to tearing or fading even under strong sun exposure.

The closed bubble design is great for reducing water evaporation—VEVOR claims it can prevent up to 95% of evaporation—which also helps keep the pool cleaner by blocking leaves and dust.

This cover is designed to increase water temperature by about 8 to 15°C, potentially extending your swimming season and lowering heating costs. One handy feature is that you can cut it to fit pools of various shapes, which adds flexibility. However, the cover is quite heavy at around 59 pounds, which might make handling and placement a bit challenging for some users. It is also recommended to hand wash it for care, which may require extra effort.

The cover floats on the water surface and is ideal for both inground and above-ground pools, especially if you want a cost-effective way to keep your pool warm and reduce water loss. If you have a pool that fits or can be trimmed to the 40 x 20 ft size, and you want a sturdy solar cover with solid heat retention and evaporation control, this product could be a good fit. Be prepared for some physical effort when installing and maintaining it.
