10 Best Pool Solar Covers 2025 in the United States

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 INTEX 28013E Solar Pool Cover is designed specifically for 15-foot round pools, making it a great choice if you have an Easy Set or Metal Frame pool of this size. Made from durable polyethylene material, it features a blue color and floating design with built-in air bubbles that help trap solar heat and transfer it into the pool water. This bubble design is important because it acts like insulation, reducing water evaporation by up to 95% and helping to keep your pool water warmer naturally. The cover also offers protection against debris like leaves and trash, which can save you time cleaning and reduce the need for extra chemicals.

While the cover doesn’t explicitly mention UV protection in the specs, the polyethylene material and bubble layer help block some sunlight, slowing down water evaporation and chemical breakdown. The 15-foot round shape fits the pool snugly, but it won’t work well if your pool is a different shape or size. Installation is easy—just lay it flat on the water surface—and it’s lightweight at 5 pounds, so handling is simple. Customers generally find the cover effective and good value, with many highlighting its efficiency at warming pools and cutting chemical use.

One downside is that it requires some care to avoid tearing, as polyethylene can puncture if handled roughly. Also, it doesn’t include extra safety features like locking mechanisms, so it’s mainly for heat retention and debris protection rather than pool safety. If your pool matches the size and shape, this cover provides a reliable, budget-friendly solution to extend your swimming season and reduce maintenance.

The In The Swim 18' x 36' Premium Blue Rectangle Solar Pool Cover is designed to heat your pool efficiently while reducing water evaporation. Made from durable polyethylene material with a thickness of 12 mil, it can raise your pool water temperature by up to 15 degrees, allowing for a longer swimming season. The light blue color allows the sun’s heat to pass through while retaining warmth during cooler nights.

Its rectangular shape and large size fit most above-ground and inground pools of similar dimensions, making it a versatile choice. The cover helps prevent evaporative heat loss, conserving water and energy. It is best used when your pool’s chlorine and pH levels are within recommended ranges to avoid damage.

The cover floats and is easy to place on the water, but removing it without a reel might be cumbersome due to its size and weight (about 51.5 pounds). Using a solar reel is recommended to make handling easier and to extend the cover’s life. Some users may find the care instructions require attention, as it needs hand washing and careful storage. This cover provides a practical and effective way to warm your pool and reduce water loss, though it requires proper maintenance and chemical balance.
