10 Best Pool Solar Covers 2025 in the United States

The In The Swim 24' Standard Blue Round Solar Pool Cover is a practical choice for those looking to extend their pool use by harnessing solar energy. With an 8 Mil thickness, this cover effectively raises pool water temperature by up to 10 degrees, offering a longer swimming season. The light blue color balances heat absorption and retention, making it efficient in maintaining warmer water. Additionally, it helps prevent heat loss during cooler nights, which is crucial for keeping your pool at a comfortable temperature. However, it's important to note that this cover should only be used under specific chemical conditions—chlorine levels below 2.5 ppm and pH levels above 7.2—to avoid damage.

Ease of use is improved with a solar cover reel, which can minimize wear and tear and simplify handling. The cover's manual installation might require some effort, especially considering its large 24-foot diameter, but it is manageable with a bit of patience. This product ranks high in its category, indicating customer satisfaction and reliability. Weighing 23 pounds, it is substantial but not unwieldy for regular use.

Made from resin, the cover likely offers good durability and resistance to the elements. Its round shape is suitable for both above ground and inground pools, providing versatility in application. Those looking for an effective way to conserve pool heat and reduce evaporation without high maintenance costs will find this solar cover a worthwhile investment. However, potential buyers should ensure they meet the pool's chemical requirements to maximize the cover's lifespan and effectiveness.

The In The Swim 18' x 36' Premium Blue Rectangle Solar Pool Cover is designed to heat your pool efficiently while reducing water evaporation.

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.

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.
