Best Solar Pool Cover in 2021

If your pool is always cold and filled with bugs and other creepy-crawlies, you need a solar pool cover.

A solar pool cover (sometimes called a “solar blanket”) is a large sheet of insulated plastic that extends the entire length of your pool. Solar pool covers serve two primary purposes: they keep insects, animals, and children out of your pool, and they use the warmth of the sun to heat your pool. This article will review the best solar pool covers on the market today.

Frequently Asked Questions (FAQ)

What is the best solar pool cover?

The best solar pool cover for rectangular pools is the HappyBuy cover because it is extremely durable. If you have a round pool, the best cover for you is the Pool Mate round cover.

Are solar pool covers worth it?

Solar pool covers are definitely worth it. A thick solar pool cover can warm your pool up 3 – 10 degrees using sunlight. This will reduce the cost of pool heating long-term and reduce the time it takes to warm your pool to a suitable temperature for swimming.

Is a thicker solar pool cover better?

While thicker solar pool covers can be more expensive, they are a great investment. Thicker pool covers absorb more heat than thinner covers, meaning they heat your water better. Thicker covers also last longer, as they are hard to pierce, durable against degrading pool chemicals, and resistant to UV rays.

How do you keep a solar pool cover from blowing off?

If your pool cover keeps blowing off, you have two options. First, you can invest in a thicker (and heavier) pool cover. Second, you can lay heavy objects like PVC pipes or pool cover weights across your cover to hold it down.


The best pool cover for you will depend on your climate, pool, and budget. If you are looking for the best buy, we recommend the HappyBuy cover for a rectangle pool and the Pool Mate cover for a round pool. We recommend the Blue Wave cover and the INTEX cover as budget buys if those are out of your price range.
