The 4 Benefits of a Solar Cover

Benefits of using a solar pool cover

1. Heats your pool water
Solar pool covers not only prevent heat from escaping but also heat your pool water. The construction enables them to trap heat underneath. The trapped heat then heats the water. The rate at which your pool water gets heated depends on the amount of sunlight it has been exposed to.

2. Budget friendly
As opposed to other options like electric and gas heating, solar covers are very affordable. They don’t cost much to buy and don’t require any running cost since they use solar power, not to mention the amount of money you get to save on water bills and chemicals.

3. Protects your pool
One of the most obvious advantages of using solar pool covers is that they cover your pool, thus protecting it against contamination by dirt and other debris. Also, by keeping your pool clean, they help your filter last longer because it doesn't have to work as hard. It also helps save on chemicals by preventing UV rays from coming into contact with your pool water.

4. Prevents Evaporation
 Whenever the sun heats your pool, it loses water through evaporation. Solar pool covers act as a physical barrier that prevents evaporation. Statistically, solar pool covers reduce water loss through evaporation by up to 80%, thus minimizing your water bill, especially in the summer

Buying Guide: 8 Factors to Consider


Quality: The material used to make the pool cover plays a crucial role in determining its quality. You should make sure that the pool cover you choose is of the best quality because the quality of the material affects not only its durability but also its ability to retain heat.


Color: The color of a solar pool cover determines its ability to trap heat. Dark-colored pool covers are the best because they absorb heat as opposed to light-colored overs that reflect heat from the sun. However, if the cover is too dark, it may have an opposite effect. You should, therefore, opt for a moderately colored or semi-transparent pool cover.


Thickness:  The thicker the pool cover, the better its heat retention capability. Thick pool covers also last longer. However, thicker solar pool covers cost more than regular covers; hence you'll need to dig deeper into your pocket.


Design:  Solar pool covers come in different designs and shapes. The most common designs include diamonds, bubble wrap-like bubbles, and hexagons. The size and shape also vary.


The Shape and size of your pool:  As discussed earlier, solar pool covers come in different shapes and sizes. You should first measure the size of your pool in terms of dimensions-for rectangular pools or diameter-for round pools.


Air bubbles:  For a solar pool cover to be fully effective in trapping heat, it must have air bubbles. You should, therefore, opt for one that has air bubbles.


Warranty:  The longer the validity of the manufacturer's warranty, the higher the quality of the solar pool cover. You should also check the terms of the warranty. Some manufacturers void the warranty if you interfere with the cover. For example, you may need to trim the cover for it to fit in your pool. You should, therefore, read through the warranty to ensure that such an action does not void it.


Trim-ability:  In some cases, you might find the solar pool cover is too big or does not fit the size of your pool. When this happens, the only choice you are left with, apart from buying another one, is trimming it. Some solar pool covers get damaged when cut. You should, therefore, consider buying one that can be trimmed without affecting its durability and effectiveness.
