Sun2Solar Clear 18 ft Round Pool Solar Cover - Heat Retaining Blanket

Our review of the Sun2Solar Clear 18 ft Round Pool Solar Cover finds it best suited to pool owners who want a simple, low-cost way to warm water and cut evaporation. The single biggest reason to buy is its straightforward solar heating: the cover harnesses sunlight to raise pool temperature by up to 15 degrees while trapping heat overnight, which makes afternoons more comfortable and reduces the need for chemical top-ups. This review focuses on real-world usefulness for both inground and above ground pools and how the cover performs in daily use.

Key Features

• Free Solar Energy: Uses sunlight to raise water temperature by up to 15 degrees, extending comfortable swim time without running a heater.
• Heat Retention: The bubble construction helps retain warmth long after sunset, maintaining a steadier water temperature overnight.
• Water Conservation: Reduces evaporation by up to 95 percent, which lowers water loss and the frequency of chemical balancing and refills.
• Debris Prevention: Stops leaves and larger debris from entering the pool, cutting down on skimming and filter maintenance.
• Easy Installation: Durable design with extra overlap lets the cover be trimmed to fit around protrusions and makes on/off handling straightforward for one or two people.

Who It's For

The cover is ideal for pool owners with an 18 ft round above ground or inground pool who want an economical way to raise water temperature and reduce evaporation without electricity. It works well for families and casual swimmers who value lower maintenance and modest heating gains from solar energy.

Those who should look elsewhere include owners seeking a permanent insulated cover or professional heating solution, and buyers who need a heavy-duty commercial-grade material, since some users report variable long-term durability and possible tearing under rough handling.

Pros & Cons

Pros

• Cut evaporation substantially, which helps conserve water and reduce chemical use over the season.
• Prevents leaves and debris from entering the pool, simplifying routine maintenance.
• Simple to install and remove thanks to the extra overlap and trim-to-fit design.

Cons

• Material durability varies by user; some report tearing after extended use, so gentle handling is advised.
