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 VINGLI 12Mil Solar Pool Heater is a heavy-duty pool cover designed to extend swimming time by warming pool water using solar energy. Made from durable polyethylene with a 12-mil thickness, it balances strength and flexibility, which helps it last longer against wear and tear. The bubble design on the underside efficiently absorbs heat and traps it in the pool, while also reducing water evaporation—this means your pool stays warmer and loses less water. Its blue color not only looks pleasant but also aids in absorbing sunlight effectively.

Sized at 18 by 36 feet and rectangular in shape, it fits many above-ground and inground pools, and you can easily trim it to match irregular pool shapes. Installation is straightforward, as the cover simply lies on the water surface, and it’s recommended to use a reel for easier handling. One thing to note is that the bubbles might look slightly deflated before warming up in the sun, which is normal due to temperature changes.

This cover requires manual installation and hand washing for cleaning. While it provides good UV protection and helps keep debris out of the pool, it does not offer the highest insulation compared to thicker or multi-layer covers. If you want an affordable and practical solar cover that helps heat your pool and reduce evaporation while keeping it cleaner, this VINGLI model is a solid choice.

The VEVOR Solar Pool Cover is a 40 x 20 feet rectangular blanket made from durable 16 mil thick polyethylene material, which makes it strong and resistant to tearing or fading even under strong sun exposure. Its blue color is standard for solar covers and helps absorb sunlight to warm the pool water. The closed bubble design is great for reducing water evaporation—VEVOR claims it can prevent up to 95% of evaporation—which also helps keep the pool cleaner by blocking leaves and dust.

This cover is designed to increase water temperature by about 8 to 15°C, potentially extending your swimming season and lowering heating costs. One handy feature is that you can cut it to fit pools of various shapes, which adds flexibility. However, the cover is quite heavy at around 59 pounds, which might make handling and placement a bit challenging for some users. It is also recommended to hand wash it for care, which may require extra effort.

The cover floats on the water surface and is ideal for both inground and above-ground pools, especially if you want a cost-effective way to keep your pool warm and reduce water loss. If you have a pool that fits or can be trimmed to the 40 x 20 ft size, and you want a sturdy solar cover with solid heat retention and evaporation control, this product could be a good fit. Be prepared for some physical effort when installing and maintaining it.
