Buying Guide for the Best Solar Blankets

Solar blankets, also known as solar pool covers, are a great way to keep your pool warm and reduce water evaporation. They work by capturing the sun's heat and transferring it to the pool water, which can help extend your swimming season and save on energy costs. When choosing a solar blanket, it's important to consider several key specifications to ensure you get the best fit for your needs.
MaterialThe material of a solar blanket is crucial because it affects durability, heat retention, and overall performance. Common materials include polyethylene, polypropylene, and vinyl. Polyethylene is lightweight and affordable but may not last as long. Polypropylene is more durable and offers better heat retention. Vinyl is the most durable and provides excellent heat retention but can be heavier and more expensive. Choose a material based on how often you plan to use the blanket and the climate in your area.
ThicknessThickness is measured in mils (thousandths of an inch) and affects the blanket's durability and heat retention. Thinner blankets (8-12 mils) are lighter and easier to handle but may not last as long or retain as much heat. Medium thickness (12-16 mils) offers a good balance of durability and heat retention. Thicker blankets (16-20 mils) provide the best heat retention and durability but can be heavier and more difficult to manage. Consider how often you'll be using the blanket and whether you need maximum heat retention when choosing the thickness.
ColorThe color of a solar blanket can impact its effectiveness. Clear blankets allow more sunlight to pass through and heat the water directly, making them ideal for cooler climates. Blue blankets are the most common and offer a good balance of heat retention and durability. Darker colors like black or dark blue absorb more heat but can also cause the water to overheat in very sunny climates. Choose a color based on your climate and how much direct sunlight your pool receives.
Size and ShapeSolar blankets come in various sizes and shapes to fit different pools. It's important to choose a blanket that matches the dimensions of your pool to ensure maximum coverage and efficiency. Measure your pool accurately and look for a blanket that either matches those dimensions or can be easily trimmed to fit. Some blankets come in standard shapes like rectangles or circles, while others can be custom-cut to fit irregularly shaped pools.
UV ProtectionUV protection is an important feature that extends the life of your solar blanket by preventing damage from the sun's ultraviolet rays. Blankets with UV protection are more resistant to fading, cracking, and deterioration. Look for a blanket that specifically mentions UV protection if you live in a sunny area or plan to leave the blanket on the pool for extended periods.
Ease of UseConsider how easy it is to put on and take off the solar blanket. Some blankets come with features like reinforced edges, handles, or reels that make them easier to manage. If you plan to use the blanket frequently, look for one that is lightweight and easy to handle. A reel system can be a worthwhile investment for larger pools, as it makes deploying and storing the blanket much simpler.
