Jimmie Meece, Model President of America’s Swimming Pool Firm, recommends UV-stabilized polyethylene for good warmth switch whereas minimizing the influence of UV rays on chlorine ranges.
Specializing in polyethylene fashions, we researched photo voltaic pool covers for effectiveness, thickness, sturdiness, ease of use, and different elements.

Our testing discovered that the perfect photo voltaic pool covers are nice at retaining warmth, however the enhance in temperature will depend on solar publicity, ambient temperature, and different elements. Some individuals will see a rise of as much as 10 levels Fahrenheit, however Meece tells us that, relying on the pool dimension, “it’s doubtless a photo voltaic cowl will solely warmth the highest 6 inches of water and won’t elevate the water temperature of your total pool.”
Along with conventional photo voltaic blankets, we additionally like photo voltaic discs (straightforward to put in and take away) for smaller above-ground swimming pools and liquid photo voltaic covers as a short-term answer that doesn’t require as a lot effort to use.

Colour and Air Bubbles
Photo voltaic pool covers are usually both clear, mild blue, silver, or a darkish blue or black. Colour isn’t an aesthetic alternative; as an alternative, the colour of the duvet determines how efficient the duvet is at transferring warmth and blocking UV rays. When it comes to warmth switch, Meece says that “clear photo voltaic pool covers are the simplest.”
He factors out that the clear materials permits the solar’s rays to simply penetrate the water beneath the duvet, however there’s a disadvantage. “They don’t block UV rays that may break down your chlorine.” In consequence, it’s possible you’ll want so as to add chemical compounds to your pool water extra regularly. Even nonetheless, it’s a terrific possibility for transferring warmth to your pool and a key cause why the Within the Swim Premium Plus Photo voltaic Blanket is our decide for the greatest UV-resistant photo voltaic pool cowl.
Air bubbles give photo voltaic pool covers their distinct bubble wrap-like texture. These are regularly discovered on photo voltaic pool blankets. The “objective of air bubbles is to entice warmth whereas concurrently insulating the warmth at evening when the solar goes down,” says Meece.
Thickness
The thickness of a photo voltaic pool cowl impacts how effectively it retains warmth and prevents evaporation, with thicker covers usually performing higher in each of these areas. Thicker covers are additionally extra sturdy than thinner ones, much less inclined to ripping, and extra more likely to final via a number of seasons. Photo voltaic pool cowl thickness is measured in mils (one mill is the same as one thousandth of an inch) and ranges between 8 and 16 mils.
- 8 mils: These pool covers are very skinny (thinner than a regular bank card), so that they’re light-weight and straightforward to deal with. They’re greatest for delicate climates as a result of they don’t present the identical warmth retention as thicker covers, however they’re additionally fairly light-weight and straightforward to deal with.

The BigXwell 1600 Sequence (our greatest heavy-duty decide) is 16 mils thick, and whereas we suggest utilizing it with a reel, we had been capable of set up and take away it by hand with two individuals regardless of the substantial weight and bulk.
Materials
The supplies of a photo voltaic pool cowl fluctuate, however all choices are non-permeable and designed to entice warmth and decrease evaporation. A few of the commonest supplies for photo voltaic pool covers are vinyl, polyethylene, or polypropylene.
- Vinyl photo voltaic pool covers are among the many most sturdy sorts of covers. The thicker materials is extra inflexible, “making them straightforward for pool homeowners to simply take away with out tearing,” in accordance with Meece. The Photo voltaic Solar Rings (our greatest photo voltaic rings) are a terrific vinyl possibility for these seeking to heat up a smaller pool.
- Polyethylene photo voltaic pool covers, like our greatest total, are “light-weight and versatile and are efficient at transferring warmth,” says Meece. He cautions that regardless of these advantages, they’re much less sturdy and will require extra frequent alternative than a vinyl photo voltaic pool cowl.
- Polypropylene photo voltaic pool covers are an alternative choice for transferring and retaining warmth. Meece says that these covers are very efficient, however the draw back is that they are often troublesome to maneuver attributable to their thickness.
