10 Best Pool Solar Covers 2025 in the United States

This solar pool cover is made from durable 12 mil thick polyvinyl chloride (PVC), a strong material designed to last while efficiently retaining heat in your pool. Its blue color not only looks attractive but also helps in absorbing sunlight to warm your water. Sized at 20 by 40 feet and rectangular, it fits most inground and above ground pools, and it can be trimmed to fit irregular shapes easily, thanks to its bubble design with bubbles facing down.

The cover offers excellent water evaporation reduction—up to 95%—which means you'll save water and reduce the need to refill your pool frequently. It also works as a barrier to keep leaves and debris out, helping to keep your pool cleaner and reduce maintenance. While the cover does not explicitly mention advanced UV protection, the PVC material and thickness contribute to durability and some UV resistance.

Installation and removal are manual, which may require some effort depending on your pool size and setup. This product is a practical, easy-to-use cover that helps warm your pool, conserves water, and keeps it cleaner throughout the swimming season.

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 28015E Solar Pool Cover is designed to fit 18-foot round pools, especially Intex Easy Set and Metal Frame types. Made from durable plastic, it uses air bubbles to capture and transfer the sun’s heat into the pool water, helping to keep your pool warm while reducing water evaporation by up to 95%. This not only conserves water but also cuts down on the chemicals needed to maintain the pool. Its blue color is common for solar covers and helps with heat absorption and UV protection.

The floating design and round shape make it easy to lay on the pool surface, and it’s lightweight at just over 8 pounds, allowing for simple handling during installation or removal. While it reduces debris, it’s not a hard safety cover, so it won’t prevent accidental falls into the pool. The cover is water-resistant and should be cleaned regularly to avoid mildew.

If you have an 18-foot round pool and want an affordable, easy-to-use solar cover that helps keep your water warm and clean while lowering evaporation and chemical use, this product fits those needs well. However, those needing extra thickness or a stronger safety feature might want to explore other options.
