You can find solar pool covers available in a wide variety of thickness options. Thickness is typically measured in mil, which is one-thousandth of an inch.

In general, the thinnest solar pool covers you can find are around 8-mil thick. These solar covers tend to be more cost-effective than thicker options, but they don’t retain heat as well. They’re best reserved for warmer climates and smaller pools.

Many of the best solar pool cover options include bonus features that can improve ease of use or efficiency. There are several things to look for that your solar cover might include:

Some solar pool covers come with a storage bag that makes it easy to carry and store them in a single compact location.

If your solar pool cover has a bag, it might also come with a dedicated carrying strap for easy transport. Weights or Grommets: Included weights or grommets can help keep a pool cover in place by allowing water to flow over the surface.

If you don’t use weights, clamps or fasteners can help to keep a solar cover snugly situated along the edge of a pool.

When your solar pool cover isn’t in use, side hangers give you a convenient place to store the cover along the edge of your pool frame.

It’s important to clean and maintain your solar pool cover to keep it free of algae, mineral deposits, and debris that can impact its effectiveness.

One of the most important considerations for many pool owners when shopping for a solar cover is their budget. A model’s cost can tell you more about the product than you might think.

If a brand gives their product a long warranty, it’s usually because they have confidence in their wares’ quality. It’s a good idea to look for solar pool covers that offer an extended warranty, as they tend to be of high quality. An extended warranty also allows you to purchase relatively risk-free.

If you’re diligent about checking prices, you’ll find that many big solar pool cover brands have regular sales. If you shop at the right time, you can find popular pool cover models at a fraction of their ticket price. Often, pool covers go on sale when the weather starts to get warm, as they’re in lower demand.

The final price of a solar pool cover can give you a fairly good indication of its quality. In general, high-end solar pool covers and well-known brand names will cost more, but they will also perform better and last longer. If possible, it’s best to avoid cheaper solar covers if your area experiences harsher weather, and instead opt for higher-quality options that will be more durable.

Yes, definitely! Here’s how: Pool water absorbs around 75% to 85% of solar energy that hits the water, keeping it warm on sunny days without using an electric or gas heater (3). While adding a solar cover can help insulate the pool, an opaque model can block the natural heat from solar rays.

A solar pool cover solves this problem by allowing more energy to reach the water beneath. In addition to trapping heat and preventing evaporation, a solar pool cover will actively heat the water as well, making it a more effective and efficient choice than traditional options (4).

The thickness of the solar pool cover that you choose will largely depend on the climate where you live as well as the size of your pool. In general, a thicker 14 to 18 mil solar cover is better, as it provides superior insulation.

Believe it or not, the color of your solar cover can have a significant impact on heating (5). If you’re looking for a solar pool cover to heat the water underneath, a transparent cover will allow in the most sunlight.

However, it will also allow more heat to escape, unlike a darker color. In general, most people choose light blue to gain a balance between heat gain and heat retention (6).
