10 Best Swimming Pool Solar Covers 2026 in the United States

The BigXwell Solar Pool Cover is a durable and effective option for maintaining your pool's temperature. Made from high-quality polyethylene (PE) material, this cover is designed for longevity and can withstand harsh weather conditions. Its 16-mil thickness and blue color help maximize heat retention by trapping solar energy using thousands of thermal bubbles. This design not only heats your pool during sunny days but also retains the warmth during cloudy days or chilly nights, ensuring a comfortable swim regardless of the weather.

The cover also significantly reduces water evaporation by up to 95%, which is beneficial for water conservation and reducing the need for frequent refills. Measuring 16 x 32 feet, it fits rectangular in-ground pools but can be trimmed to suit pools of various shapes and sizes, making it versatile. However, at 50.9 pounds, it might be a bit heavy for some users to install or remove without assistance.

Its floating installation type is simple, although it requires regular manual care, such as hand washing with mild detergent and air drying.

The In The Swim 20' x 40' Ultra Silver Rectangle Solar Pool Cover is designed for effective solar heating of both above-ground and in-ground pools. With a substantial 16 Mil thickness, this cover can increase water temperature by up to 18 degrees, making it ideal for extending your swimming season. The silver color enhances light penetration, which helps in rapid temperature increase. It also effectively prevents evaporative heat loss during cooler nights, thus maintaining the warmth of the pool water.

However, it requires careful monitoring of chlorine and pH levels to ensure longevity and performance. Chlorine levels should be below 2.5 ppm, and pH levels above 7.2 when using this cover. Utilizing a solar cover reel can improve convenience and reduce wear and tear, but it may add to the initial setup cost. The cover is well-rated, holding a 4.4 out of 5 stars from 414 customer reviews, indicating general satisfaction among users.

Given its size, shape, and UV protection, this cover is suitable for large rectangular pools, and its bubble design aids in effective heat retention. However, its weight (58 pounds) might make handling challenging without a reel. This solar cover is a good investment for pool owners looking to maintain a warm pool temperature with minimal heat loss.

The VEVOR Solar Pool Cover is a solid choice if you want to keep your swimming pool warmer and reduce water evaporation. Made of durable 12 mil thick polyethylene with a blue color and bubble design, it traps heat effectively—raising your pool water temperature by up to 15°C in ideal conditions. This can help extend your swimming season and lower heating costs. The bubble pattern is also great for reducing evaporation, saving water, and cutting down on pool cleaning since it helps keep debris out.

Its rectangular shape (32 by 16 feet) fits many pools and can be trimmed for a custom fit, which adds flexibility if your pool isn’t a perfect rectangle. The material is strong and resists sun damage, so it should last without fading or tearing easily. However, being a floating cover, it might not be the best if you want something that completely seals the pool surface. Also, its size means it’s better suited for medium to large rectangular pools.

This solar cover provides a practical and affordable solution for pool owners who want simple, effective heat retention and water conservation without complex installation.
