Solar pool covers are a versatile addition to your pool and go beyond just providing pools with a temperature boost. They also help to keep your pool clean and debris-free, which means less work skimming and cleaning and more time swimming and floating. With their bubble wrap-like appearance, the best solar pool covers retain the heat already in your pool and add to it, especially on days filled with sunshine. These covers also act to prevent up to 95% of water loss through evaporation. This, in turn, reduces the amount of cleaning chemicals you’ll lose over the season, making your pool better for the environment and saving you time and money in the process.

What To Look For In A Solar Cover

It’s important to know the dimensions of your pool. Some covers can be cut for irregular shapes, but others come in finished sizes.

Do you have an above-ground or in-ground pool? In-ground pools tend to be larger and require a pool cover reel for their solar covers. Above-ground pools are often round in shape and their covers can be installed and removed by hand.

Light-colored solar covers are a better value. Blue covers look nice with water, but the lighter the cover, with clear being the best, the thicker the material and the longer it will last.

How We Chose The Best Solar Covers

Below, you’ll find the best solar pool covers available right now. There are options for both round and rectangular pools. These can also be cut down for use in irregular-shaped pools. We included models that are specifically for above-ground pools, as well as options for in-ground designs. Our list includes customer-favorite brands and covers that are highly rated for their quality and value.

Check out our top picks below and don’t forget to use your cover bubble-side down, which keeps the cover afloat and acts as magnifying glasses to turn the sun’s rays into a heater for your pool.

1. Sun2Solar Blue Rectangle Solar Cover

The Sun2Solar Blue Rectangle Solar Cover is available in a range of different sizes, including the most common swimming pool sizes (like 15 by 30 feet). The cover comes in either blue or clear and includes a bubble-filled film which gives an eye-catching appearance. This design also works to retain and collect heat, even at night and on chilly days. In addition, this cover helps to minimize water evaporation, meaning you’ll have to fill your pool less often over the season.

2. In The Swim Basic Round Pool Solar Blanket

The In The Swim Basic Round Pool Solar Blanket is definitely worth adding to your pool when you consider the potential of an eight to 10-degree increase in water temperature after seven days of consistent sunlight.

The 8-mil thick solar cover can raise the temperature of pool water by an average of 15 degrees Fahrenheit, making it a great option for pools that don’t have built-in heaters.
