Solar Pool Covers: Pros and Cons

Swimming pool ownership comes with decisions about maintenance, comfort, and cost savings. One of the most discussed accessories is the solar pool cover, designed to harness the sun’s energy and keep your pool warmer while reducing water and chemical loss. Like any pool accessory, solar covers have both benefits and drawbacks that pool owners should consider before making a purchase.

What is a Solar Pool Cover?

A solar pool cover, often called a solar blanket, is made of a durable plastic material embedded with air bubbles that resemble bubble wrap. These bubbles capture and transfer the sun’s heat to the water while also acting as a barrier to evaporation. Covers come in different thicknesses and sizes to fit various pool shapes.

Pros of Solar Pool Covers

1. Energy Savings

Heating a pool can be costly. A solar pool cover reduces the need for gas or electric heaters by using the sun’s natural energy, lowering energy bills significantly.

2. Heat Retention

Solar covers not only warm the water but also help retain heat overnight when temperatures drop. This makes swimming more comfortable during cooler evenings.

3. Reduced Water Evaporation

Water loss through evaporation is one of the biggest concerns for pool owners. A solar cover can reduce evaporation by up to 95 percent, conserving water and keeping chemical levels stable.

4. Chemical Savings

When less water evaporates, fewer pool chemicals are lost. This means you spend less money replenishing chlorine and other treatments, keeping your pool balanced more easily.

5. Extended Swimming Season

With warmer water and reduced heat loss, pool owners often enjoy an extended swimming season, especially in areas with mild but cooler nights.

6. Eco-Friendly Choice

Solar covers reduce reliance on non-renewable energy sources by harnessing solar energy, making them an environmentally friendly option.

Cons of Solar Pool Covers

1. Manual Handling

Unlike automatic covers, most solar covers need to be manually placed and removed. This can be inconvenient, especially for larger pools.

2. Storage Challenges

When not in use, solar covers require proper storage. Rolling and unrolling them can be awkward without a reel system, and improper storage may cause damage.

3. Limited Safety Benefits

Solar covers are not safety covers. They cannot support weight or prevent accidental falls into the pool, so additional safety measures are necessary.

4. Durability Issues

Although durable, solar covers can wear out over time, especially with heavy sun exposure or rough handling. Most covers last three to five years before needing replacement.

5. Aesthetic Concerns

Some pool owners find that the appearance of a solar cover detracts from the beauty of their backyard or outdoor space.

Tips for Maximizing Solar Cover Benefits

1. Invest in a reel system to make placing and removing the cover easier.

2. Choose the right thickness for durability and heat retention. Thicker covers often last longer.

3. Cover the pool whenever it is not in use to maximize savings on heat and evaporation.

4. Store properly by keeping the cover out of direct sunlight when rolled up, as prolonged exposure can cause damage.

5. Clean the cover regularly to prevent buildup of dirt and algae.

Should You Get a Solar Pool Cover?

Solar pool covers can be a smart investment for many pool owners, particularly those looking to cut heating costs, save water, and extend their swimming season. However, they do come with maintenance and handling challenges that need to be considered. By weighing the pros and cons, you can decide if a solar pool cover is the right addition to your pool care routine.
