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 Blue Wave NS530 14-mil Solar Blanket is a solid choice for owners of rectangular in-ground pools around 20 by 40 feet. Its 14-mil thickness is on the higher side, which helps it conserve pool heat effectively—potentially raising water temperature by up to 15 degrees Fahrenheit. The clear color allows sunlight to pass through and warm the water while the tightly packed thermal bubbles provide good insulation during cooler nights or cloudy weather.

Made of durable plastic with UV-resistant properties, this cover is built to handle sun exposure and pool chemicals over time, which should extend its lifespan. The floating design makes it easy to place and remove as needed, and it comes with a reassuring 6-year warranty. On the downside, at 40 pounds, it can be a bit heavy to handle alone, and its size and rectangular shape limit it to pools close to those dimensions. Also, while clear covers let sunlight through, they may show dirt or debris more readily than darker colors.

This blanket is well suited for pool owners seeking efficient solar heating and durability without complex installation.
