Solar Pool Cover Colors Explained

Does color really matter?


When you are looking for a solar pool cover, you may notice there are many different colors out there. Which colors best capture the rays of the sun and give you the most bang for your buck? When you are shopping around you can see light blue, gray, dark blue and even green. What solar pool cover color is the best? This article will explore your different options in a solar pool cover.

There are many opposing viewpoints out there as to what solar pool cover color is best. There is one school of thought that believes the darker your solar pool cover color, the better. There is another group that thinks a clear cover is the best. It is important to know how a solar pool cover or blanket works to understand which color will best meet your needs.

A solar pool cover does not actually “heat” your pool. Instead, the solar pool cover takes the rays from the sun and works with the solar pool blanket to do a couple of things. One, the solar pool cover prevents evaporation. Two, the solar pool cover will allow the sun’s rays to enter the pool water. The rays will heat your pool and the cover will keep the warm water in your pool.

All colors can work. A black cover will absorb the most of the sun’s rays and that cover will get the hottest. However, that does not mean that the water under the cover will reach the same temperature. A black or dark blue solar pool cover may work more quickly, but the water on the surface is what will be the warmest. A black or dark cover will also break down more quickly since the sun’s energy is getting absorbed in that cover the most.

A clear or light blue cover will allow more of the sun’s rays to enter your pool. A darker pool cover can actually block some of the rays from getting into your pool, thus defeating the purpose of the solar pool cover. According to government sources, a dark cover could block up to 40 percent of the sun’s rays. A clear cover can block up to 15 percent. So it is clear if you want more of the sun’s rays to enter your pool to heat it – then choose a clear cover.

Since a dark cover can work more quickly by grabbing more of the sun’s rays, and a clear cover lets in more of the sun’s rays to actually heat your pool, many people choose a color in the middle, such as blue. This way, both effects can be accomplished and you can have a nice, warm, energy-efficient pool that you can use more months out of the year.
