#1
Winner
Blue Wave NS525 Rectangular 18 x 36-ft In-Ground Pools-Clear 14 mil Solar Blanket, 18x36ft Rectangle
The Blue Wave NS525 14-mil Solar Blanket is designed for rectangular in-ground pools sized 18 by 36 feet. Made of durable plastic with a clear color, it features 14-mil thickness—thicker than many basic solar covers—helping it last longer and resist damage from UV rays and pool chemicals. The blanket’s bubble design insulates well, trapping heat and raising water temperature by up to 15 degrees Fahrenheit, which is great for extending your swimming season without additional heating costs. It also effectively minimizes heat loss overnight and on cloudy days, thanks to tightly packed thermal bubbles. Another strong point is its ability to reduce water and chemical evaporation by up to 95%, saving both water and maintenance expenses.

Buying Guide for the Best Pool Solar Covers
Choosing the right pool solar cover can make a significant difference in maintaining your pool's temperature, reducing water evaporation, and keeping debris out. When selecting a pool solar cover, it's important to consider several key specifications to ensure you get the best fit for your needs. Understanding these specifications will help you make an informed decision and enjoy a more comfortable and efficient swimming experience.MaterialThe material of a pool solar cover is crucial because it affects durability, heat retention, and overall performance. Common materials include polyethylene, polypropylene, and vinyl. Polyethylene is lightweight and affordable, making it suitable for mild climates. Polypropylene is more durable and offers better heat retention, ideal for moderate climates. Vinyl is the most durable and provides excellent heat retention, perfect for colder climates. Choose a material based on your climate and how often you plan to use the cover.
ThicknessThickness is an important factor as it influences the cover's insulation properties and durability. Pool solar covers typically range from 8 mils (thousandths of an inch) to 16 mils. Thinner covers (8-12 mils) are lighter and easier to handle, suitable for warmer climates where heat retention is less critical. Thicker covers (12-16 mils) provide better insulation and are more durable, making them ideal for cooler climates or if you want to maximize heat retention. Consider your climate and how much insulation you need when choosing the thickness.
ColorThe color of a pool solar cover affects its heat absorption and retention capabilities. Common colors include blue, clear, and black. Blue covers are popular for their balance of heat absorption and aesthetic appeal. Clear covers allow more sunlight to penetrate, providing better heat retention but may not be as effective at blocking debris. Black covers absorb the most heat and are excellent for warming the pool quickly, but they can make the water too hot in very sunny climates. Choose a color based on your preference for heat retention and how much sunlight your pool receives.
Size and ShapeGetting the right size and shape is essential for effective coverage and performance. Pool solar covers come in various sizes and shapes to fit different pool dimensions. Measure your pool accurately and choose a cover that matches those dimensions. Some covers can be trimmed to fit irregular shapes. Ensure the cover fits snugly to prevent heat loss and debris from entering the pool. Consider whether you need a custom-fit cover for uniquely shaped pools.
UV ProtectionUV protection is important because it extends the lifespan of the pool solar cover by preventing damage from the sun's rays. Covers with UV inhibitors are more resistant to wear and tear, ensuring they last longer and maintain their effectiveness. Look for covers that specifically mention UV protection, especially if your pool is exposed to a lot of direct sunlight. This feature is particularly important in sunny climates where UV exposure is higher.
Bubble DesignThe bubble design on a pool solar cover helps with heat retention and insulation. The bubbles trap heat and transfer it to the water, keeping the pool warm. Different covers have varying bubble sizes and patterns. Larger bubbles can provide better insulation but may be bulkier, while smaller bubbles are more flexible and easier to handle. Consider the bubble design based on your preference for ease of use and the level of insulation you need.
