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 Sun2Solar Blue 24 ft Round Pool Solar Cover is made from polyethylene, a durable material known for its resistance to wear and tear. This solar cover is designed to raise the pool water temperature by up to 15 degrees Fahrenheit using the sun's natural energy, which can be very beneficial for extending the swimming season. The cover is a solid blue color and features a round shape, making it suitable for both above-ground and in-ground swimming pools of similar dimensions.

The 800 Series bubble design aids in trapping heat, ensuring that the water remains warm even overnight, and providing thermal insulation benefits. Additionally, it helps in preventing up to 95% of water evaporation, which is great for saving on water and reducing chemical usage for pool maintenance. The cover also acts as a barrier against leaves and debris, making pool cleaning less frequent and more manageable.

Installation is straightforward due to its lightweight design, and it can easily be adjusted to fit around any protrusions in the pool. However, users have noted that while the material is durable, it may not be the thickest available, potentially affecting long-term heat retention and UV protection. The cover’s durability might also require users to handle it gently to avoid punctures. This cover seems well-suited for pool owners looking to conserve water, reduce maintenance, and increase the pool temperature using solar energy, but it may require careful handling to maintain its longevity.
