How We Chose The Best Solar Pool Covers

We used some very straightforward criteria to choose our favorites. We looked for versatility, durability, and ease of use.


We know that not all pools are created equal, so we looked for covers that come in a large variety of sizes and were easy to cut to fit any shape. Being able to trim your pool cover to fit any size is especially important if you have a custom in-ground pool. You may think that the unique shape of your pool could keep you from making efficient use of solar heating, but that is not the case. No matter what shape your pool is, you can find an option that can be trimmed to fit the custom shape of your pool.


Nobody wants to waste money on products that are not going to last. That is why we looked for covers that were made out of quality materials that would be able to withstand strong pool chemicals as well as constant exposure to UV rays. We also looked for options that had good warranties, so you could feel confident in your purchase.

Ease of Use

Using a pool cover is usually an easy process, but some elements can make it easier. That is why we chose a few lightweight options. If you are trying to handle a pool cover by yourself, having a lightweight option can make maneuvering it a lot easier which means you will use it more often. If the cover is too heavy or cumbersome, then you probably won’t use it as much which means it would just be a waste of money. The lightweight materials also make these covers easier to fold up at the end of the season which means they can be stored properly and used for many seasons to come.

What You Need To Know About Solar Pool Covers

There are two main elements to consider when choosing the proper solar pool cover: size and color.


The reason we keep mentioning the sizes of these covers and how they can be trimmed to fit is because having the cover properly fitted is the most important element of a pool cover. You want to make sure that the cover you choose covers the entire surface of the water. The reasons for this are efficient heating, proper protection, and reduced evaporation.

Efficient Heating

The main purpose of a solar pool cover is to help increase the heat in your pool without having to use expensive electric or propane heaters. If your pool cover does not cover the entire surface of the water, it will not be able to heat efficiently. These covers not only absorb solar heat, but they also work as a type of blanket to hold the heat in. If the cover does not reach across the entire pool, heat will escape around the edges leaving you with a chilly swimming experience.


Another useful element of a well-fitted pool cover is that it helps to keep your pool free of outdoor debris such as sticks, leaves, and anything else that happens to blow by. A properly fitted cover will catch more of the debris, keeping it out of your pool. This will save you cleaning time as well as increase the life of your pool filters by blocking debris before it gets that far.

Reduced Evaporation

We also mentioned how these pool covers can decrease evaporation, some up to 95%. This can only happen if the cover is fitted correctly. If the cover is too small, then water will simply evaporate around the edges. This not only affects the amount of water you have to pump into your pool but your pool chemicals as well. Your pool cover will keep your water and chemical levels stable, saving you time and money. Saving water is also environmentally friendly, so that is another benefit of reduced evaporation.


The color of your pool cover is a slightly less important element, but it is still worth mentioning. There are two main colors to choose from: blue and clear. Although you wouldn’t think that this would make much of a difference, it certainly can.

The blue option is best for those who want less of the heating benefit, but still want protection and reduced evaporation. Although blue covers will still increase the heat of your pool, they will not increase the heat as much as a clear cover.

Clear covers allow more direct sunlight into your pool, thus creating more heat. Some clear covers can increase the temperature of the pool as much as 15 to 20 degrees, which may be too much for some people. If you want extra heat, choose a clear cover. For a slightly cooler pool experience, choose a blue cover.

Bottom Line

Choosing a solar pool cover can benefit you in several ways. It can increase the temperature of your pool without adding inconvenient energy costs. Using solar power is also more environmentally friendly, making this a better option for everyone. A pool cover can also save you time and money when it comes to pool cleaning, water usage, and maintaining proper chemical balances.

It’s hard to go wrong with any of our top solar pool cover picks, but we recommend the Thermo-Tex Solar Pool Cover for its ease-of-use, durability and versatility. Compare all of your options before making a final decision, though, to make sure that you’re choosing the right model for your circumstances.
