10 Best Liquid Solar Pool Covers 2025 in the United States

The VINGLI 12Mil Solar Pool Cover is designed for both inground and above-ground pools, measuring 20x40 feet, and is made from durable polyethylene material. One of its main benefits is its ability to extend swimming time by absorbing and releasing heat through its bubble design. This cover provides effective temperature retention, which can help keep your pool warmer for longer periods. Additionally, it significantly reduces water evaporation, aiding in water conservation and maintaining pool levels.

This is particularly beneficial in warmer climates or areas with water restrictions. The cover is also easy to install and can be cut to fit pools of various shapes, making it versatile and user-friendly. It helps keep the pool clean by preventing debris from falling into the water, which can save time and effort on maintenance. The heavy-duty material and strong welded seams promise long-lasting use, although the large size means it can be quite heavy to handle, especially when wet. For added convenience, using it with a pool cover reel is recommended.

While it offers good safety features by covering the pool's surface, it is crucial to note that it may not replace a dedicated safety cover for preventing accidents. Some users might find the manual installation and removal process slightly cumbersome due to its weight. If there are any issues with the product, VINGLI provides customer support for assistance.

The BigXwell Solar Pool Cover is designed to provide effective coverage for a 12 x 24-foot in-ground pool. It excels in temperature retention thanks to its 16 mil thick material with thousands of thermal bubbles that harness the sun's heat, maintaining a warm pool even on cloudy days and chilly nights. This can significantly reduce the need for expensive heaters, making it energy-efficient and cost-effective.

Additionally, it helps protect your pool by keeping out dust, leaves, and debris, thereby reducing maintenance efforts and costs. The cover also minimizes water and chemical evaporation by up to 95%, meaning you won't have to refill your pool as frequently, saving both water and money. Made from high-quality polyethylene, the cover promises durability under harsh weather conditions.

It's lightweight, making it easy to install and remove, although its size and weight (26.5 pounds) might be a bit challenging for some users to handle alone. Safety is a consideration, as it provides a barrier to reduce chemical evaporation, though it's essential to ensure it's securely in place to prevent any potential hazards. This cover is a solid option for anyone looking to maintain a cleaner, warmer, and more cost-efficient pool environment.

The In The Swim 16' x 32' Premium Blue Rectangle Solar Pool Cover is a solid choice for both above-ground and inground pools. One of its standout features is the 12 Mil thickness, which can increase pool water temperature by up to 15 degrees, allowing for an extended swimming season. This cover strikes a balance with its light blue color, which aids in both heat absorption and retention. Additionally, it effectively reduces evaporative heat loss during cooler nights, which can help maintain a more consistent pool temperature.

It's important to note that the cover should only be used when chlorine levels are below 2.5 ppm and pH levels are above 7.2, which may require some monitoring and adjustment on your part. For ease of use, pairing the cover with a solar cover reel is recommended, as this can make applying and removing the cover more convenient and reduce wear and tear. On the downside, the cover weighs 35.9 pounds, which might be cumbersome for some users to handle without assistance.

This solar pool cover offers significant benefits in terms of temperature retention and evaporation reduction, but users should be mindful of the chemical balance in their pool and the potential difficulty in handling its weight.
