How Do I Choose the Best Solar Pool Cover?

You return from a long week of work travel, and all you want to do is take some laps around your refreshing pool. All you can think of is how relaxing it’ll be, but there’s a problem. It’s Fall, and the pool’s going to be too chilly to enjoy. You feel disappointed, fix yourself a bath, and decide to make do with that. But what if we told you that you can extend your swimming season long after summer, by doing something as simple as buying a solar pool cover?

The operation of a pool cover is basic - it transfers heat from sun rays to your pool, thereby raising its temperature. Needless to say, they’re a great way of saving on energy costs. We understand that choosing the right pool cover can be tedious since there are so many factors to consider, and sometimes you don’t even know what to look for in the first place!

That’s the purpose of this review - to point out these factors and guide you toward the pool cover that best suits your needs. Firstly, let’s look at the different types of solar pool covers based on function, design, and shape. Here they are:
  • Bubble Covers: These covers have air bubbles on the underside of the pool cover that trap and transfer heat to your pool. It further seals the heat and keeps it from going back into the atmosphere. They’re mostly UV-ray-protected making them last longer, even in harsh sunny conditions, but eventually deteriorate with prolonged exposure to the sun. They’re made of polyethylene and polypropylene materials with different thickness gauges from 8 Mil to 16 Mil. The thicker covers retain more heat but are usually a chore to roll away, while the lighter covers are easy to roll away but don’t retain as much heat. Like a traditional cover, they keep dirt out of the pool, thereby reducing the number of times you need to clean the pool.
  • Solar Ring Pool Covers: These are small spheres that are attached to each other with a magnet and placed on the surface of the pool. The idea behind these covers is to leave as little room as possible for the sun rays to hit the pool directly, thereby reducing algae buildup in the pool. The ring cover has a few advantages over the bubble cover. When a pet falls into the pool, the ring covers separate and don’t wrap up the pet like the bubble cover would do, and you can change sections of the ring cover each time without having to change the full cover. However, they neither retain heat nor reduce evaporation, and there is room for chemical dissipation when using the solar ring cover
There are also pool covers classified based on colors: blue and clear. It’s believed that blue covers retain heat more than the clear covers, but the clear covers heat the pool faster. There are also classifications based on shape: round, oval, rectangular, and kidney shapes.

It is advisable to run your pool pump while using the solar cover so that you will get a uniform rise in temperature in your pool. Also keep in mind that some solar covers are better for above-ground pools, and others for in-ground swimming pools.
Considering the different types of pool covers discussed above, it’s certain that different factors affect the price of covers in the market. For instance, a pool cover with a higher thickness gauge should cost more than that with a lower gauge. People make the mistake of thinking that the more expensive a product is, the higher the quality, but that’s not always true; nonetheless, you would not expect a high-quality pool cover to cost less than a low-quality one.

A good solar pool cover costs between $71 and $369 and truthfully, they pay for themselves through the seasons when you compare the cost of the solar cover to the energy cost of heating your pool with a pump instead. Of course, we saw some cheap solar pool covers while researching this product, but we ignored them because most of the reviews showed that they live true to their names; cheap. So, rest assured, whatever solar pool cover you get from this review is of good quality.
Size, shape, and design are among some of the factors that influence the pool cover you choose, but beyond these, there are other features that affect your choice and the price of your pool cover. For instance, you need to buy a pool cover that will fit into the shape or design of your pool without sinking into the pool, and you need to get a pool cover with enough thickness to keep your pool as warm as you need it. Here are some of the factors that affect the type of pool cover you decide to purchase:
  • Thickness
  • UV Resistance
  • Color
  • Degree of Rise in Temperature
  • Portability
  • Shape
  • Accessories
  • Size and Fitting
  • Material
  • Durability
  • Warranty
Let’s look at these factors one by one and see why they’re important to consider before choosing a solar pool cover.
Construction and Design
Most solar pool covers have thickness gauges ranging from 8 Mil to 16 Mil; there are even some that have a thickness gauge as low as 5 Mil. The thickness of your pool cover determines how well it will retain heat in the pool. The thicker covers tend to retain more heat and keep more water from evaporating from your pool; they also hold up better against debris and dirt falling into the pool, and cannot be blown away by the wind easily. However, they’re not strong enough to keep pets from falling in, and they’re usually bulkier to roll away. If you’re getting a thicker pool cover, it’s best to get a second person to help roll it away.

Research has shown that darker colors retain trapped heat in the pool better than clear colors, but heat the pool slower than the clear colors; this is simple physics. The blue color, for instance, already has a color which absorbs rays from the sun as it hits the cover. This means that the color absorbs a fraction of the sun rays. But for the clear ones, nothing absorbs the rays; the heat is transferred directly to the pool; and then, the reverse is the case when it has to do with heat retention. However, there are blue/clear solar covers that are hybrids of both colors. Depending on which is a priority for you (heat absorption or heat retention), you can choose the color that best suits you.

Solar pool covers come in different shapes: oval, rectangular, and round. When going for a pool cover, choose one that fits the shape of your pool. It’s usually hard to find a kidney-shaped pool cover, but you can buy a rectangular one and cut it into the shape of your kidney pool.

Check if your cover comes with accessories such as a reel and seam holder. Though pool covers with these accessories will naturally cost more, they’ll save you the stress of searching for them in the market again. And the reels that come with the covers have been made to suit them.

The thicker your cover, the more warranty cover it will have. Some have a shorter full warranty and a longer limited warranty. This means that if your pool cover starts breaking within the full warranty period, you may get a replacement. Always check what your warranty covers.
Performance and Ease of Use
Solar pool covers are built to work under the sun, so it’s in your best interest to get those that are UV-resistant; this treatment affects the durability of your pool cover. Ideally, pool covers are expected to last for two seasons on average, but if your cover is UV-resistant, it can outlast the seasons.

The major function of the solar pool cover is to raise the temperature of the pool, so it should be the first thing to consider. To what degree will your pool cover raise the temperature of your pool? There are covers that raise the temperature up to 20 degrees Fahrenheit but, on average, they raise it up to 10 degrees Fahrenheit. It’s up to you to know what degree you can accommodate or want to achieve, and go for the cover with that feature.

It’s better to buy a bigger pool cover and cut it to fit than to buy a smaller one. The latter will make you lose the sole purpose you bought the cover for. There will be evaporation and chemical dissipation from the sides of the pool that are exposed. Needless to say, this will make heat retention a harder job for your pool cover to do.
