How Does A Solar Pool Cover Work?

How Does A Solar Pool Cover Work?

Solar pool covers, also known as solar blankets, are essential for pool maintenance because they keep debris out of pools while minimizing evaporation and capturing solar energy. They are like giant piece of heavy-duty bubble wrap that traps the sun’s heat and insulates the pool at night.

Solar blankets are made of UV-resistant plastic and vary in thickness depending on the product, from just several mil to 16 or more. Note that mil doesn’t stand for millimeters and is a unit of measurement that is one-thousandth of an inch.

If your pool has a heater, these covers reduce your energy bills, and if your pool is unheated, it allows the pool to be warmer than the air temperature. The air bubbles in the cover allow UV rays to heat the pool via heat transfer naturally. The air bubbles then work as insulation during the night, helping to keep the warmth in the pool when the air temperature dips.

How To Use A Solar Pool Cover ?

How To Use A Solar Pool Cover?

You want your solar pool cover to fit correctly, so you may need to cut it with sharp scissors if it isn’t the ideal size and shape. A proper fit is especially challenging for custom-sized or irregularly shaped pools, such as kidney-shaped pools.

The cover should fit snuggly along the water's surface up to the pool's edge. Therefore, the cover must not drape over the sides of the pool.

Place the cover on the water, bubbles side down, so the thermal pool cover is floating on the surface. Most pool owners use the covers whenever they aren’t swimming and especially overnight. Read More >>

When using the pool, remove the cover and avoid leaving it in direct sunlight, which causes the plastic to degrade prematurely. For convenience, some pool owners install a reel to roll up the cover, or else they cut it into large segments to make it easier to move. Another option is to store it in a bag and place it in a garage or shed.

Why Should You Buy A Solar Pool Cover?

Many swimming pool owners with solar blankets are thrilled because they save time and money while conserving resources.

Benefits To Using A Solar Blanket For Outdoor Pools:

Factors To Consider When Purchasing A Solar Pool Cover

Let’s explore some of the top considerations when purchasing a solar blanket:

UV Resistance

UV Resistance: The pool cover material can avoid degradation from ultraviolet radiation from the sun.The plastic in the pool cover breaks down and disintegrates over time due to the chemical bonds in polymers breaking down from sunlight. Note that clear covers tend to have better UV resistance than blue ones.

Material & Thickness

Material & Thickness: In colder or windier climates, a solar pool cover with a thickness of 14 or 16 mil is ideal. However, a 10 or 12 mil thermal pool cover in warmer climates is sufficient and costs a bit less than a thicker model.

Color

Color: Most pool covers are clear, blue, or silver. Some experts recommend a blue pool cover because it helps prevent the breakdown of pool chemicals and is a bit more effective at trapping the sun’s heat. However, clear pool covers tend to last longer because they have more excellent UV resistance.

Size Of Your Pool

Size Of Your Pool: It’s critical for the cover to fit correctly to function well. If the cover is too large, you can cut it down using scissors to the proper size and shape. However, avoid buying a pool cover that is too small because it will not work properly.

Air Bubbles

Air Bubbles: Solar pool covers are lined with little air bubbles because air helps insulate your pool. When temperatures dip at night, the bubbles help with heat retention.

Cost

Cost: Larger and thicker pool covers tend to cost more than thinner and smaller ones. Also, some pool owners buy a solar cover reel system for removing and storing the solar blanket, which increases the total cost.

Warranty

Warranty: Although some solar pool covers have warranties, they are often prorated over time. Also, some warranties require the customer to pay the shipping costs, which makes the warranty less helpful.

Tips To Maintain Solar Pool Covers

When properly maintained, solar pool covers typically last for two to five seasons. Apply the following tips to help keep your cover in good condition.

Tips To Maintain Solar Pool Covers
  • Remove debris regularly, including leaves
  • Avoid storing the pool cover in direct sunlight when not in use
  • Hose it down periodically to remove dirt
  • Once in a while, scrub off stuck dirt gently with a mild soap and allow it to dry completely before storing
  • Maintain proper chemical levels in the pool
  • Keep a repair kit in your home and if rips form, fix them immediately before they expand
  • Don’t use the cover during the winter months when the pool isn’t in use, but replace it with a cover specifically made for colder weather
  • When it rains, remove water that pools on top of it

Bottom Line

A solar pool cover is an excellent way to save time and money while helping to maintain a warmer pool. However, don’t be disappointed if the cover only lasts two to three years, especially if you live in a hot, sunny climate. The above list of the top 5 pool covers provides comprehensive details to help you make an informed decision based on your needs and budget.

Frequently Asked Questions (FAQs)

Here are some of the commonly asked questions:

What Solar Cover Is Better, Clear Or Blue?

There are advantages and disadvantages to each. Blue pool covers absorb more light than clear solar pool covers. Therefore blue covers are more effective at transferring the heat to the pool and retaining the heat. 

Although both blue and clear covers will help insulate your pool, a clear pool cover will stay cooler and therefore release more heat. Also, blue covers are more effective at preventing the degradation of pool chemicals from UV radiation. 

However, clear cover lasts longer because it can stay cooler in the sun. The price of both clear and blue solar pool covers are similar, so there isn’t an advantage or disadvantage related to the cost.

Should I Leave Solar Cover On The Pool During The Day?

The answer to this question depends on your climate, goals, and the cost of water in your area. If you live in a dry or windy climate, keeping the cover on during the day might be helpful to prevent evaporation. However, the evaporation rate decreases in a warm, humid climate, so taking off your pool cover might be worthwhile. If you want to keep your pool warmer overnight, it is essential to keep it on at night to maintain a warmer temperature.

Can I Run My Pool Pump With Solar Cover On?

Yes, you can run your pool pump with the cover because it doesn’t hinder its operation. Keeping the pool cover on reduces the amount that the pool pump needs to run, extending the life of the equipment.

Do Solar Pool Covers Cause Algae?

Pool covers don’t cause algae growth because they prevent debris and rainwater from entering your pool. However, if you do not remove debris once it has entered your pool water, algae can grow in your pool water.

Are Solar Pool Covers Safe?

In general, pool covers are safe for pets and children. Unfortunately, if water collects over a pool cover, this can create a dangerous situation because a child can drown in just an inch or two of water. Sadly, there have been cases of several young children playing in the yard, falling into the water that collected on the pool cover, and drowning.

When it rains, use a pump to remove the water that collects on the cover. Although this will not altogether remove all moisture, it will prevent water from collecting and posing a threat. Another way to make your pool safer is to install a fence around it.

When Should You Use A Solar Pool Cover?

These pool covers are beneficial at preventing the evaporation of water, saving energy, and keeping your pool warm. It is especially critical to use the cover at night when the air temperature drops because it works to insulate the water from cooler temperatures. Often, it is also helpful to use the cover during the day to help heat the water and prevent evaporation.

How Much Warmer Does A Solar Cover Make A Pool?

Pool covers can increase your pool water temperature by 10 to 15°F. Not only do they harness the power of the sun to heat your pool water, but they also insulate the pool at night when the air temperature is cooler.
