Solar pool covers, or solar blankets, are key for your pool’s performance. They use the sun’s energy to warm the water and cut heating expenses by 50% to 70%. Like bubble wrap, they let sunlight warm the pool and keep the heat in at night, boosting their effectiveness.
An outdoor pool grabs 75% to 85% of solar energy that hits it. This makes the water 10 to 15 degrees Fahrenheit warmer. Also, a solar pool cover lowers evaporation by up to 95%, saving water and chemicals. Since 1,048 Btu of heat is needed to evaporate each pound of 80ºF water, less evaporation means more energy saved.
Knowing how solar pool covers work helps make your pool more eco-friendly and efficient. They keep the pool clean by blocking dirt and leaves. They also save water by cutting down on the need for extra water by 30% to 50%. This means you can start swimming in April or May, not just in June.
What Are Solar Pool Covers?
Solar pool covers, often called solar blankets, use the sun’s energy to warm your pool. They also cut down on water loss and the need for chemicals. Made from materials like polyethylene and polypropylene, they’re light and partly see-through. These covers work well to keep heat in, making them good for the planet and for pool owners alike.
Types of Solar Pool Covers
There are different solar pool cover types out there to fit what you’re looking for. Here are some common ones:
- Clear Solar Covers: They let lots of sunlight through, warming your pool well.
- Blue Solar Covers: These are tough and look good, balancing heating and UV protection.
- Blue-Silver Solar Covers: These have a blue top and a silver bottom to keep more heat in.
Each kind of cover has its own way of keeping heat and saving energy. Clear covers are great at warming your pool but might not last as long as blue or blue-silver ones.
Materials Used in Solar Pool Covers
Solar pool cover materials play a big role in how they perform and last. Common ones are polyethylene and polypropylene, which are light and see-through. This makes them look like bubble wrap, which helps with heating your pool.
Let’s look at how different solar pool cover materials: compare.
| Material | Characteristics |
|---|---|
| Polyethylene | Light, absorbs lots of sunlight, affordable |
| Polypropylene | Lasts a long time, UV resistant, keeps heat really well |
| Vinyl | Strong, for heavy use, best in tough conditions |
Choosing the right material can make solar pool covers much more effective. For example, the Michigan Energy Office found that a vinyl cover cut energy use by 50% for one pool. This shows it works well in different weather.
How Do Solar Pool Covers Work?
Many pool owners often ask, “how do solar pool covers work?” These covers are key for keeping pools warm. They also cut down on water evaporation a lot. By understanding how they function, you can get the most out of them.
The Science Behind Solar Absorption
Solar pool covers soak up UV rays from the sun. They have a special layer with tiny air bubbles. These bubbles work like tiny magnifying glasses, boosting the sun’s warming effect. Thanks to this, the cover can warm up your pool water by up to 15°F (8°C) on clear days. This means you can enjoy swimming for weeks longer, depending on where you live.
Heat Retention Mechanisms
An important part of how solar pool covers function is by keeping heat in. When it’s cold or night, the cover stops heat from escaping the water. This is great because it can keep almost all the heat from the day, slicing heating costs by half. Also, a top-notch solar pool cover helps pool chemicals work longer by reducing how much you need by up to 30% and shields them from the sun’s harsh UV rays.
Knowing how these covers work shows why they’re smart buys. They’re good for both your wallet and the environment. The way they’re made, including the color and type of stuff in them, makes them excellent for warming and taking care of your pool.
| Benefit | Details |
|---|---|
| Increased Temperature | Raises water temperature by up to 15°F (8°C) |
| Reduced Evaporation | Decreases water evaporation by approximately 90% |
| Cost Savings | Lowers heating costs by up to 50% |
| Chemical Efficiency | Reduces chemical usage by up to 30% |
| Extended Lifespan | Solar pool covers typically last between 3 to 5 years |
Benefits of Using Solar Pool Covers
Solar pool covers offer many benefits that make owning a pool better and more efficient. They not only warm up the pool water but also save a lot on energy and costs.
Energy Savings on Heating Costs
One big plus of solar pool covers is how much they save on heating. They can cut heating costs by up to 50% by keeping heat in. This is because they use the sun’s energy to raise water temperatures by up to 8°C, which means less need for electric or gas heaters.
Using a solar pool cover also means you can swim for more of the year. It keeps the water warm for longer, letting you swim more without paying more for heating. This makes pool running costs lower and helps the environment too.
Reduction in Water Evaporation
Solar covers cut down on water evaporation a lot. They can stop up to 98% of pool water from evaporating. This is key for keeping water levels up and saving water, especially with today’s environmental worries.
Besides, with less water evaporating, you don’t need to add water and chemicals as much. This keeps the pool’s chemical balance steady and lowers the amount of chemicals you need. It saves money and makes the pool healthier to swim in.

Key Features to Look For
When picking a solar pool cover, think about how long it will last. The thickness and material quality show how durable and effective it is.
Thickness and Durability
Solar pool covers range from 250 microns (0.25 mm) to 600 microns (0.6 mm) in thickness. Thicker ones, like those 500 microns or more, keep in more heat. They also last longer because they’re tougher. A 300-micron cover might last 5 years, but a 500-micron cover can go up to 8 to 10 years.
Also, thicker covers cut down on water evaporation by up to 95%. This saves energy and money.
UV Resistance and Lifespan
The ability to resist UV rays is vital for a solar pool cover lifespan. Covers with good UV resistance avoid harm from sunlight, keeping their efficiency longer. This means you get more benefits for a longer time. Special materials and coatings combat UV damage, keeping the cover in good shape and working well.
| City | Temperature Increase (Summer) | Temperature Increase (Spring) |
|---|---|---|
| Melbourne | 4-6°C | 3-4°C |
| Sydney | 6-8°C | 4-6°C |
| Brisbane | 6-8+°C | 4-6°C |
| Perth | 6-8+°C | 3-6°C |
Choosing a cover with the right thickness and UV protection improves solar pool cover durability. It also increases the solar pool cover lifespan. This makes sure your investment is worth it in the end.
Installation and Maintenance Tips
Correctly installing a solar pool cover can hugely affect its effectiveness. The cover’s bubbles should face down into the water. This helps warm the pool better. Trim the cover to fit your pool, but let it slightly overhang for full coverage. This maximizes the cover’s efficiency.
Proper Installation Techniques
First, measure your pool accurately before installing the cover. Make sure the bubble side touches the water. This ensures the pool warms up properly. Covers come in different thicknesses like 8 mil, 12 mil, and 16 mil. Thicker covers keep the heat better and last longer. For pools with unique shapes, you can order customized covers. A cover roller makes putting the cover on and off easier, which helps it last longer.
Cleaning and Care Guidelines
Keeping your solar pool cover clean is key. Clean it regularly to stop debris and chemicals from damaging it. After using the pool, or if a storm is coming, fold the cover off to protect it. Keep the pool’s chlorine under 2.5 ppm and pH above 7.0 when the cover is on. This keeps the cover from getting damaged. When winter comes, dry the cover well and store it inside. This stops it from getting damaged by the cold.
Using a cover reel helps protect the cover when you’re not using it. It makes handling the cover easier and keeps it in good shape. By taking care of your solar pool cover with these tips, you’ll extend its life. These actions save money on energy and keep your pool fun and inviting for years.
