Sun2Solar Clear 18 ft x 40 ft Rectangle Pool Solar Cover - Heat

In this review of the Sun2Solar Clear 18 ft x 40 ft Rectangle Pool Solar Cover the bottom line is simple: it is a practical, low-effort way to raise and hold pool temperature while cutting evaporation. The reviewer found the cover best suited to owners of rectangular inground or above ground pools who want a straightforward solar blanket that increases daytime water temperature and reduces overnight heat loss. The single biggest reason to buy is heat retention-it consistently keeps water several degrees warmer and reduces the need for extra chemical top-ups.

Key Features

• Free Solar Energy: Uses direct sunlight to raise pool water temperature by up to 15 degrees in favorable conditions, reducing heater runtime.
• Traps Heat: The cover retains warmth long after sunset so evening swimming is more comfortable and thermal loss overnight is reduced.
• Conserves Water: Cuts evaporation by up to 95 percent, which helps maintain chemistry balance and reduces frequent water additions.
• Debris Prevention: Stops leaves and common yard debris from entering the pool, lowering routine skimming and filter strain.
• Easy Installation: Durable design with extra overlap and 6 heavy-duty grommets makes it simple to position and trim to fit around fittings or ladders.

Who It's For

The Sun2Solar solar blanket is ideal for pool owners who want to passively increase water temperature without electrical heaters and who have a rectangular pool up to 18 ft x 40 ft. It fits both inground and above ground pools and suits families or weekend users looking to extend comfortable swim hours while cutting water loss.

Those who should look elsewhere include buyers seeking a multi-season heavy-duty commercial cover or customers wanting a permanent safety cover; this product is a thermal blanket focused on heat retention and evaporation control rather than a rigid safety solution.

Pros & Cons

Pros

• Raises daytime water temperature and reduces overnight heat loss, improving swim comfort.
• Significantly reduces evaporation, which helps retain pool chemicals and water level.
• Stops most leaves and debris from entering the pool, simplifying maintenance.
• Simple to install with extra overlap and 6 grommets for anchoring or trimming to fit.

Cons

• Durability reports are mixed; some users note it may not last a full season under heavy use.
• Bubble size and material thickness vary by perception, so some buyers expect a thicker, longer-lasting blanket for the price.
