10 Best Pool Solar Covers 2025 in the United States

The BigXwell Solar Pool Cover is designed to harness solar energy to heat your pool. Its 16-mil thickness and thermal bubble design are effective in trapping heat from the sun, which can warm up the pool during sunny days and maintain the temperature during cooler nights. The polyethylene material promises durability and longevity, even under harsh weather conditions, while also being lightweight and easy to install or remove.

The blue color of the cover not only looks appealing but also contributes to UV protection, which is crucial for minimizing water evaporation – claimed to be reduced by up to 95%, helping conserve water significantly. Additionally, the cover can be trimmed to fit pools of various shapes, making it versatile for both in-ground and above-ground pools.

However, at 50.9 pounds, it might be a bit heavy for some users to handle. Given its size of 16 x 32 feet, it is suitable for larger pools. This cover is a robust option for those looking to efficiently heat their pool and reduce water evaporation, with the flexibility of fitting different pool shapes and sizes.

The Sun2Solar Blue 20 ft x 40 ft Rectangle Pool Solar Cover is designed to harness solar energy to heat swimming pools, providing a cost-effective solution to raise water temperatures by up to 15 degrees. A notable strength of this cover is its ability to retain heat, which helps keep the pool water warmer overnight. Additionally, it effectively reduces water evaporation by up to 95%, which can save on water replacement and chemical costs. This feature is beneficial for pool owners looking to conserve resources and maintain the pool's chemical balance.

Made from resin, the cover is lightweight, making it easy to install and remove. It also incorporates a bubble design, which enhances its thermal insulation capabilities. The cover’s blue color is practical for absorbing sunlight, and its rectangular shape and size make it suitable for large inground or above-ground pools but may not fit non-standard or smaller-sized pools without some adjustment.

The inclusion of 6 heavy-duty grommets adds to its durability, providing extra support for secure placement. This solar cover is UV resistant, ensuring longevity under sun exposure. This product is ideal for pool owners with large rectangular pools who are looking for a straightforward and efficient way to heat their pool while minimizing water and chemical loss.

The Blue Wave NS530 14-mil Solar Blanket is a solid choice for owners of rectangular in-ground pools around 20 by 40 feet. Its 14-mil thickness is on the higher side, which helps it conserve pool heat effectively—potentially raising water temperature by up to 15 degrees Fahrenheit. The clear color allows sunlight to pass through and warm the water while the tightly packed thermal bubbles provide good insulation during cooler nights or cloudy weather.

Made of durable plastic with UV-resistant properties, this cover is built to handle sun exposure and pool chemicals over time, which should extend its lifespan. The floating design makes it easy to place and remove as needed, and it comes with a reassuring 6-year warranty. On the downside, at 40 pounds, it can be a bit heavy to handle alone, and its size and rectangular shape limit it to pools close to those dimensions. Also, while clear covers let sunlight through, they may show dirt or debris more readily than darker colors.

This blanket is well suited for pool owners seeking efficient solar heating and durability without complex installation.
