As long as you clean and care for your cover and pool regularly, you shouldn't have any problems.Įrica Puisis has been covering the best products for outdoor and indoor living at The Spruce since 2017. Also, make sure rain water doesn't get stuck on top of your solar pool cover, as this can increase the risk of algae growth as well. Having low chlorine levels in your pool can cause algae to grow very rapidly. A number of factors can cause algae growth, including the presence of nitrates, very warm temperatures, rain water, and imbalanced chemicals. Solar covers made of these materials block some UV radiation while still allowing for solar heating.Īlthough it could be argued that higher temperatures in pool water may cause algae to grow, solar pool covers alone don't typically cause this. Silver or light blue covers, that fall in between opaque and transparent, are often a good compromise. Clear solar covers allow the sun’s rays to pass through to the water below and can result in the largest temperature rise, but also frequently cause an increased need for chlorine. Opaque (or solid color) pool covers block UV rays that impact pool chemistry but also result in less passive heating from solar energy. You also have choices regarding the color of the solar cover. Polyethylene and polypropylene covers are very common choose a thicker cover if you want one that is more tear-resistant. Vinyl pool covers are very durable but can be heavy.

There are three primary materials for solar pool covers: vinyl, polyethylene, and polypropylene. Typically, you find 8, 12, or 16 mil options, though other thicknesses (like 14 mil) are sometimes seen, as well. The thickness of a solar pool cover is measured in millimeters. Additionally, thinner pool covers typically allow more of the sun’s energy to reach the water below the cover-but also may allow for more heat loss during the night. Thicker pool covers are less likely to tear or rip when putting the cover on your pool or removing it. Thickness is an important consideration when buying a pool cover since it impacts how heavy the pool cover is along with its durability. You may also need to trim a pool solar cover for a uniquely shaped pool such as a kidney pool. If you’re in between solar pool cover sizes, go with the larger size. However, know that you can trim most pool covers to fit your pool's specific size and shape without voiding the manufacturer’s warranty. What to Look For in a Solar Pool Cover SizeĬhoose a solar pool cover that approximately matches the dimensions of your pool. Made of 8 mil thick resin, this is not the thickest solar pool cover on the market but it gets the job done.
#SOLAR POOL COVER SERIES#
For a budget-friendly choice, we recommend the Sun2Solar 800 Series cover ( view at Walmart). This rectangular cover features thick plastic construction, which makes it excellent at retaining heat and preventing evaporation. The Sun2Solar 1200 Series Rectangle Solar Pool Cover ( view at Amazon) is our top choice. It can even be trimmed to better fit your pool, if it’s between sizes. This light blue cover is a more versatile option for homeowners that are looking for a pool cover to keep out debris, lock in heat at night, and absorb the sun’s energy during the day. Although clear solar pool covers transmit more of the sun’s energy into the water, they also let in more UV rays that cause significant changes to pool water chemistry-requiring more chemicals to avoid algae and maintain ideal water conditions. The surface of the light blue cover absorbs UV rays from the sun, while the bubbles transmit the absorbed energy into the water. However, this cover can be prone to rip because of its thin construction, so always be cautious when rolling it up and storing it during the off-seasons.Īir bubbles cover the bottom of the Sun2Solar pool cover place them face down in the water, leaving the smooth side facing up. Made of a flexible resin, this cover is durable enough to withstand the elements yet thin enough to transmit solar heat. This pool cover from Sun2Solar is our top pick because it is available in a variety of sizes and it keeps your pool warm after a long day in the sun.
