10 Best Swimming Pool Solar Covers 2025 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 VEVOR Solar Pool Cover is a 40 by 20 feet rectangular cover made from a strong 16 mil thick polyethylene material. This thickness helps make it durable and resistant to tearing or fading, even after long exposure to the sun. Its blue color is typical for pool covers and helps in absorbing heat. The cover features a closed bubble design, which is great for reducing evaporation—up to 95% less water loss—saving water and protecting your pool. It also traps heat effectively, potentially raising your pool’s temperature by 8 to 15 degrees Celsius, which means you can enjoy swimming for a longer season without extra heating costs.

The cover’s rectangular shape fits well on similarly shaped pools, and it can be trimmed to fit other shapes if necessary. Additionally, it keeps debris like leaves out, reducing cleaning time. It’s designed for pools with specific water chemistry (chlorine levels below 2.5 ppm and pH above 7.2), so it might not perform as well if these conditions aren’t met. The cover weighs about 59 pounds, so handling it may require some effort. Cleaning requires hand washing, which is fairly common but worth noting.

This cover represents a solid choice for someone looking to save water, maintain pool temperature, and reduce maintenance in medium to large rectangular pools.

The VINGLI 12Mil Solar Pool Cover is a robust choice for both inground and above-ground swimming pools. Made from heavy-duty polyethylene (PE), the material promises durability and longevity. Its 12Mil thickness contributes to effective heat absorption and retention, allowing for extended swimming time even during cooler periods.

The transparent blue color aids in solar heat absorption and visually complements most pool settings. Sized at 20x40 feet in a rectangular shape, it suits large pools and can be easily cut to fit any irregular shapes, giving users flexibility in installation. The bubble design on the cover maximizes heat transfer, reducing water evaporation and conserving pool water levels.

The UV protection feature helps in maintaining the cover's integrity against sun damage. Installation is straightforward, though it may require manual effort, and using a cover reel is recommended for ease. At 51.9 pounds, it is relatively heavy, possibly making handling cumbersome for some users. This solar cover is ideal for pool owners who prioritize energy efficiency, water conservation, and cleanliness, while also being prepared for the manual effort required during installation and removal.
