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 BigXwell Solar Pool Cover is designed to help heat in-ground pools naturally by harnessing sunlight, which can save you money on electric or gas heaters. Made from durable polyethylene with a solid blue color, it’s a heavy-duty option that resists wear from weather and pool chemicals. At 16 mil thickness, it strikes a good balance between toughness and flexibility, making it relatively easy to handle despite weighing over 50 pounds.

Sized at 18 by 36 feet with a rectangular shape, it fits larger pools well. This cover floats on the water’s surface to trap heat and reduce water and chemical evaporation, which also helps keep your pool cleaner by blocking debris like leaves and dust. While the product doesn’t explicitly mention UV protection, the material’s thickness and quality imply decent resistance to sun damage, contributing to its longevity.

The cover is straightforward to install and remove with a pull-on closure style, though its size and weight might require some effort or assistance. One limitation is that it’s specifically sized, so if your pool shape or size varies significantly, it might not provide a perfect fit. Also, as a floating cover, it offers less protection than solid safety covers against accidental pool entry. This solar pool cover suits pool owners looking for an affordable, energy-saving way to maintain warmer water while reducing maintenance, especially for medium to large rectangular pools.

The BigXwell Solar Pool Cover is a solid choice for in-ground pools measuring around 12 by 24 feet. Made from durable polyethylene and featuring a 16-mil thickness, it is thick enough to provide effective insulation and heat retention. The blue color helps absorb sunlight while being visually appealing. Its rectangular shape fits standard pool dimensions well, and the floating installation makes it easy to use without complicated setups.

This cover traps solar heat through thousands of thermal bubbles, helping to naturally warm your pool water and maintain temperature even on cloudy or cooler days, which can reduce the need for electric heating and lower energy costs. Additionally, it helps cut down on water and chemical evaporation by up to 95%, meaning less frequent refilling and chemical balancing—good for both your wallet and pool maintenance. The cover also protects against debris like leaves and dirt, keeping your pool cleaner for longer.

While the polyethylene material is sturdy and weather-resistant, it may eventually show wear from prolonged sun exposure, so storing it when not in use is recommended to extend its life. This model does not specify UV protection coatings, which some other covers include for extra durability. BigXwell’s solar blanket provides a practical balance of heat retention, protection, and ease of use, making it a helpful accessory for pool owners looking to save on heating costs and maintenance effort.
