Recap: The Best Solar Pool Covers

Our Research Criteria

Solar pool covers are not only simple to install, but also affordable for some pools (automatic covers are more expensive to install). We understand that finding the right solar pool cover can be tedious, and that’s why we decided to do some research and help you settle on a great one for your setup. Below are some factors we used in our research criteria. As long as you’re searching for affordable ways to heat your pool, also be sure to check out my guide on liquid solar covers, a decent alternative to blankets.

Inground vs. Above Ground Pools

There are specific pool covers designed for above ground pools that won’t work for inground pools and vice versa. The size of your pool is another essential consideration. You can find solar pool covers that you can cut to fit the size of your pool, but it’s vital to know the measurements of your pool.

Solar pool covers are also sold in various shapes. Make sure to take measurements of your pool before buying one, and you can also use multiple solar blankets if you have a freeform pool, or get a custom one made.

Bubble Blankets vs. Solar Rings

Solar pool covers can be either bubble covers or solar ring covers. Bubble covers are affordable and easy to handle. The bubbles absorb the sun’s heat and transfer it to the water during the day, while at night, the bubbles turn into insulators.

Most bubble covers are UV-ray resistant, which means they can withstand direct sun exposure. Moreover, they are lightweight, something that allows you to put them on and take them off with ease, you just need to know which way to face your bubbles. Bubble covers can have polyethylene or polypropylene materials.  You can find them in different thicknesses that range from 8- 16 gauge. Thicker materials trap heat and are more durable.

Solar ring pool covers are efficient and work to improve solar collection in your pool. These covers have rings that, when attached, create a raft on the surface of the pool through magnets.  You can remove the rings when you need to skim and vacuum. The uncovered space also allows light to pass.

The Type of Material and Color

Solar covers for pools are made from different materials like vinyl, polyethylene, or polyurethane. Vinyl covers are resilient and durable, thanks to their heavy-duty protection. Solar pool covers are available in various colors. It’s best to opt for dark-colored covers as they protect against heat. Avoid covers that are too dark as they can keep the pool cooler. Semi-transparent covers are an excellent option as they allow UV rays to pass through and get in the water.

Manual vs. Automatic

Contrary to popular belief, not all pool covers are simple to use. These covers can be manual, automatic, and semi-automatic models.  Automatic solar covers only need you to push a button to roll and unroll the cover. Semi-automatic covers have a reel system and use electric power to remove the cover, but you need to guide the movement. With manual models, you’ll need to adjust them with your hands.
