10 Best Solar Swimming Pool Covers 2025 in the United States

The In The Swim 15' Standard Blue Round Solar Pool Cover is made from an 8 mil thick material designed to help warm your pool water by up to 10 degrees, which can extend your swimming season. Its light blue color strikes a nice balance by absorbing and holding heat without getting too hot. The cover’s bubble design helps trap heat and reduces water evaporation, especially during cooler nights.

This cover fits round pools well, both above ground and inground, and weighs about 10 pounds, making it manageable to handle. It is recommended to use it only when your pool’s chlorine is below 2.5 ppm and pH is above 7.2 to avoid damage. While it doesn’t come with a reel, using one can make putting the cover on and taking it off easier, and also helps it last longer.

This cover is a good choice for pool owners looking to save energy on heating and reduce water loss, but it requires proper chemical balance and some care to maintain. Its popularity and positive ratings suggest many find it effective and reliable.

The Sun2Solar Blue 18 ft Round Pool Solar Cover is designed to harness solar energy to heat your pool, making it suitable for both inground and above-ground pools. Made from resin, this cover is durable and lightweight, weighing only 4.24 pounds, which makes it easy to install and remove. The cover is round in shape and has an 18-foot diameter, ensuring it fits a variety of pool sizes.

Its blue color is aesthetically pleasing and helps with heat retention, raising the pool temperature by up to 15 degrees. The bubble design maximizes heat retention and helps keep the water warm overnight, while also preventing up to 95% of water evaporation, which conserves water and reduces chemical consumption. Additionally, it stops debris from entering the pool, reducing maintenance efforts.

However, the cover's lightweight nature, while making it easy to handle, might not offer the same level of durability and thermal insulation as heavier options. Users should also consider that while installation is straightforward, ensuring the cover fits perfectly around protrusions might take some time and adjustment. The hand wash-only care instructions could be seen as a minor inconvenience for some users. This product demonstrates a solid performance in maintaining pool temperature and cleanliness, making it a good choice for pool owners looking to reduce maintenance and heating costs.
