10 Best Solar Pool Covers 2025 in the United States

The BigXwell Solar Pool Cover is a 16-mil thick polyethylene cover designed for in-ground pools, measuring 16 by 32 feet in a rectangular shape. Its blue color helps it absorb and trap solar heat effectively, which warms your pool on sunny days and helps maintain temperature when it's cloudy or cool. This makes it a great choice if you want to swim in warmer water without extra heating costs. The cover features thousands of small thermal bubbles that boost heat retention and reduce water evaporation by up to 95%, saving you from frequent refills and water waste.

It’s lightweight and easy to handle, and can be trimmed with scissors to fit pools of various shapes, adding versatility. The material is durable enough to withstand harsh weather, but since it's polyethylene, it requires gentle care like hand washing and air drying to maintain longevity. One downside is that it floats on the water and doesn’t have a rigid locking system, so it may shift during windy conditions. Also, while the cover offers good insulation and UV protection, it’s primarily suited for use during the warmer months and may not be as effective in extreme cold.

If you have a rectangular in-ground pool and want a cost-effective way to keep your water warm and reduce evaporation, this cover offers a combination of durability and practical features that make it a solid choice.

The VEVOR 32 x 16 ft solar pool cover is designed to help keep your pool warmer and reduce water loss. Made from durable 16 mil thick polyethylene material, it offers good resistance to tearing and sun damage, which means it should last through strong sunlight without fading or warping. Its blue color is common for solar covers and helps absorb heat efficiently. The large rectangular size fits many pools, and you can trim it to better match your pool’s exact shape.

Thanks to its bubble design, it can increase your pool’s temperature by 8-15°C, extending your swimming season and lowering heating costs. It also cuts down evaporation by up to 95%, saving water and reducing how often you need to add more. The cover floats on the water and keeps leaves and dust out, making pool maintenance easier.

The 16 mil thickness provides good durability but is not the thickest available, so extremely harsh conditions might wear it out faster than heavier covers. Also, because it’s a large sheet, handling and storing it can be a bit bulky. This cover is a solid choice for pool owners looking for an affordable, effective way to keep their pool warm and clean, especially if you want something customizable and easy to use.

The Sun2Solar Blue 20 ft x 40 ft Rectangle Pool Solar Cover is designed to help heat and maintain the temperature of rectangular inground or above-ground pools. Made from resin material with a solid blue color, it offers good UV resistance to protect the pool water from sun damage and helps retain heat efficiently. This cover can raise pool water temperature by up to 15 degrees and reduce overnight heat loss, which is a solid feature for those wanting to extend their swimming season.

It also conserves water by preventing up to 95% of evaporation, which means fewer refills and chemical adjustments. The 20 by 40 feet size matches standard pool dimensions well, and the rectangular shape fits typical pool layouts. The inclusion of six heavy-duty grommets can make it easier to secure the cover in place. Users will find it lightweight and easy to handle, making installation straightforward.

With a good balance of heat retention, evaporation prevention, and debris blocking, this solar cover is a practical choice for pool owners who want simple and effective heating support without complicated installation or maintenance. The cover requires hand washing only, meaning it needs gentle cleaning to be maintained well.
