10 Best Pool Solar Covers 2025 in the United States

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.

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 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.
