Sun2Solar Clear 16 ft x 36 ft Rectangle Pool Solar Cover

The 1600 Series by Sun2Solar is designed to cover large rectangular pools, both above ground and inground. This 16 mil cover aims to capture solar energy to raise water temperature by up to 15 degrees Fahrenheit. It also focuses on heat retention overnight to maintain a stable pool temperature. A notable feature is its grommets, which help secure the cover against breezes and storms. The cover also dramatically reduces evaporation, potentially cutting chemical use and water needs by up to 95% in some conditions.
In The Swim 16′ x 32′ Ultra Silver Solar Pool Cover

This 16-mil thick cover emphasizes heat retention and solar warming to naturally elevate pool water temperature while conserving energy costs. The design reduces evaporation and keeps water from cooling overnight, extending the swimming season. Its 16-mil construction provides durability and tear resistance, with wide seams intended for long-lasting performance. Suitable for both above-ground and in-ground pools, it balances strength with efficient heat capture.
Solar Pool Cover 16 Mil 16 x 32 Ft (Blue)

This blue 16-mil pool cover is built to maximize solar absorption and transfer heat to the water. It helps lower heating costs by dimming nighttime heat loss and protecting water from debris. The bubble layer provides a barrier that traps heat while keeping the surface clean, making maintenance easier and less frequent during swimming season. It’s suitable for both inground and above-ground pools of similar dimensions.
In The Swim 20′ x 40′ Ultra Silver Solar Pool Cover

This larger cover follows the same 16-mil standard with enhanced heat retention and solar warming. Its broad surface area is ideal for big rectangular pools, enabling efficient warming through abundant solar capture while reducing nighttime heat loss. Its construction emphasizes durability and resistance to tearing, offering dependable performance across multiple seasons. Evaporation control remains a core benefit, helping conserve water and chemical resources.

This clear option by Sun2Solar emphasizes maximum visibility for inspection while emphasizing heat capture. The 16 mil thickness ensures durability against wind and debris, while the 16 x 32 ft footprint suits mid-size rectangular pools. It claims strong heat-trapping properties and significant evaporation reduction—up to 95% in optimal conditions—helping to extend swimming seasons without added energy consumption. The design enables straightforward removal and secure anchoring with compatible accessories.
Buying Guide: Key Purchase Considerations
When selecting a 16 mil ultra clear pool solar cover, consider heat retention, evaporation control, and durability. All options described provide heat capture and several emphasize overnight heat retention to extend your swimming season.
- Pool size and shape: Choose a cover that matches your pool dimensions. Most options here cover common rectangular inground or above-ground pools; confirm length and width before purchase.
- Material thickness: 16 mil is a standard heavy-duty thickness offering durability and efficient heat transfer, while remaining manageable for removal.
- Heat retention vs. solar warming: Some covers emphasize warming the water during the day, while others focus more on keeping heat overnight. For best results, select a model that balances both.
- Durability features: Look for wide seams and reinforced edges, plus grommets or fasteners for secure anchoring in windy conditions.
- Evaporation control: A primary benefit of these covers is reducing water loss. Consider models with a proven reduction rate (commonly up to 95%).
- Debris protection: Bubble-backed designs help keep debris out of the pool when not in use, easing maintenance.
- Maintenance and compatibility: Ensure the cover is compatible with any existing pool covers, reels, or tenting systems you may use for storage.
- Longevity and warranty: Check for warranty information and user reviews about tear resistance and seam integrity over multiple seasons.
From a practical standpoint, the best choice depends on pool size, local climate, and whether you prioritize maximum heat retention or easier cleaning and debris protection. For large pools, a bigger 20′ x 40′ option may deliver the most uniform heat capture, while mid-size covers provide excellent balance for typical residential pools. Durability features matter if you face strong winds or seasonal use.
