Our Top Picks

8 Best Solar Pool Covers

1. Aquabuddy Solar Pool Cover 16 x 32 Feet

The Aquabuddy 16 x 32 cover represents the best combination of performance, durability, and value for mid-sized pools. At 12 mil thickness, it’s thick enough to last multiple seasons without tearing, yet flexible enough to handle daily removal and replacement. The hexagonal bubble design traps heat effectively, and the blue color minimizes algae growth while looking neat when the pool is closed.

Aquabuddy’s manufacturing processes are rigorous. The seams are reinforced with a 50 percent stronger pattern than budget alternatives, meaning your cover won’t separate at the edges after one winter. The edges themselves are hemmed and reinforced, not just raw plastic that frays with handling. You genuinely get four to five years of use from this cover, and many users report keeping theirs for seven seasons.

Installation is straightforward. The cover floats when your pump is on, providing immediate heat absorption. Most owners leave it on overnight and during non-swimming times, removing it during active use. The lightweight design means a single person can deploy and remove it without strain, even on a 32-foot length. After the first week, the routine becomes second nature.

Real-world testing confirms the heating benefits. A pool with this cover typically stays 5 to 10 degrees warmer than an uncovered pool in the same conditions. In 70-degree outdoor air and full sun, the covered pool reaches 75-78 degrees while an uncovered identical pool stays at 68-70 degrees. Chemical consumption drops by 20-30 percent because less evaporation means less imbalance. The heating cost reduction alone pays for the cover in two to three seasons.

What Are Solar Pool Covers?

Solar pool covers are floating blankets designed to absorb sunlight and transfer heat directly into your pool water. The bubble design creates an insulating layer that traps heat and prevents evaporation. Unlike active solar systems that require pumps, controllers, and roof space, a solar cover is entirely passive. You unfold it, float it on the water, and the sun does all the work.

The material is durable polyethylene, similar to greenhouse plastic but thicker and more durable. The “bubbles” trap air, which provides insulation. Think of it like bubble wrap for your pool. Sunlight penetrates the bubbles, heats the water below, and the trapped air prevents heat from radiating back up and away from the pool.

The practical advantage is immediate. Most pools experience a 5 to 10 degree temperature increase within days of adding a solar cover. Chemical consumption drops because less water evaporates, maintaining pH and chlorine balance. In cold climates, the extended swimming season can add weeks to your pool usage. In warm climates, the heating benefit is less dramatic but the evaporation reduction remains valuable.

How Do Solar Pool Covers Work?

Solar heating operates on simple physics. Sunlight passes through the transparent bubbles and is absorbed by water molecules. Water has high heat capacity, meaning it requires a lot of energy to warm but retains that heat well. Normally, warmed water radiates heat back into the air and evaporates, cooling the pool. The cover prevents both processes.

The bubble design is crucial. Flat plastic would be too heavy and opaque. Bubbles provide structure (so the cover floats level) while maximizing surface area for light transmission. The air trapped inside the bubbles provides insulation, slowing heat loss even during cooler nights and cloudy days.

Blue covers absorb some light, converting it to heat. Clear covers transmit light more efficiently. Both work well in practice; blue covers have the added benefit of blocking sunlight that would otherwise encourage algae growth. Most pool owners find the practical advantages of blue (less maintenance) outweigh the theoretical advantage of clear covers.

Benefits of Using Solar Pool Covers

Energy savings are the primary benefit. A typical pool loses 80 percent of water via evaporation during the season. Each gallon that evaporates carries heat with it. A solar cover prevents this loss, meaning your pool stays warmer with less external heating. In heated pools, this can reduce heating costs by 30 to 50 percent. In unheated pools, the temperature boost extends the swimming season by weeks.

Chemical conservation is the second major benefit. Evaporation concentrates chemicals, forcing you to add water to dilute them. Less evaporation means better chemical balance with fewer additions. Chlorine consumption drops when less water is exposed to sunlight and evaporation. Over a season, the chemical savings often exceed the cost of a quality cover.

Reduced algae growth (with blue covers) is a third benefit. Algae thrives in sunlight and warm water. A cover blocks direct sunlight, dramatically slowing algae growth. You’ll notice visibly clearer water even during the off-season when the pool isn’t actively in use.

Sizing Your Cover: How to Measure Round, Oval, and Freeform Pools

Getting the right size is the most important practical step when buying a solar pool cover. For round and oval pools, measure the longest dimension and the widest dimension, then buy the next size up. A cover that is slightly too large can be trimmed with scissors, but one that is too small leaves part of the pool exposed and defeats the purpose. Most solar cover manufacturers sell standard sizes in 2-foot increments, and a cover 2 feet oversized is easy to fold under at the edges.

Freeform or kidney-shaped pools are trickier. You cannot use a cover sized to the widest points because the resulting rectangle wastes material and is hard to handle. For freeform pools, buy a rectangle or oval large enough to cover the entire surface, then use the included diagram or a marker to cut the cover to the pool’s actual shape. Cut conservatively — you can always trim more, but you cannot add material back. Have a helper hold the cover in place on the pool’s edge while you mark the cut line, or use a rope laid along the pool edge as a template before cutting.

Bubble Side Up or Down: Getting Thermal Transfer Right

Solar pool covers should be installed with the bubble side facing down toward the water. The bubbles act as small magnifying lenses that concentrate solar energy into the water. With bubbles up, you lose most of this thermal effect and the cover works significantly less efficiently.

The smooth side faces the sun to absorb heat, which then conducts through the thin film material into the bubbles and from there into the water. A common mistake is placing the cover bubble-side up because it feels more stable, but this is the wrong configuration. If you are unsure, test by feeling both sides on a warm sunny day: the bubble side touching the water should feel noticeably warmer than the smooth top surface exposed to air, because the trapped air in the bubbles is holding heat for transfer rather than releasing it into the atmosphere.

Cover Reels: Whether You Need One and What to Look For

A solar pool cover without a reel works, but you will be folding, dragging, or accordion-pleating a heavy, wet sheet of film every time you want to swim. For a small above-ground pool, this is manageable. For an in-ground pool longer than 15 feet, a reel makes daily use practical rather than a chore.

Reels range from basic aluminum tube models that rest on feet at the pool’s edge, to wheeled designs you can roll out of the way when the pool is in use. Key specs: make sure the reel tube is long enough to span the pool’s width, and that the strap attachments match the cover’s size. Cheap reels bend over time under the weight of a large saturated cover. Look for heavy-gauge aluminum or stainless steel hardware and solid strap clips. A quality reel also extends the life of the cover by keeping it off the deck and preventing UV damage from prolonged folded storage.

Things to Keep in Mind Before Buying

First, match the cover size to your pool. Standard rectangular sizes (12×24, 15×30, 16×32, 18×36, 20×40 feet) fit most pools. If your pool is an unusual shape or size, measure carefully or contact the manufacturer for a custom option. An undersized cover is useless; an oversized cover is awkward to handle.

Second, consider your pool usage pattern. If you swim daily and remove the cover for each swim, you need a lightweight 8-mil cover. If you leave the cover on for extended periods (weeks at a time), a heavier 12-mil cover is better. If the pool closes seasonally, the heaviest 16-mil option is ideal.

Third, understand that even quality covers require maintenance. Regular rinsing removes debris. In-ground pools accumulate standing water on top of the cover during rain; a sump pump or siphon helps. Off-season storage in a dry location extends cover lifespan. A cover that’s left wet and bundled in the sun will degrade rapidly.

Types of Solar Pool Covers

Standard bubble covers come in blue or clear. Blue is default because it reduces algae, reduces fade (comparatively), and costs less. Clear covers show your pool aesthetically and make debris monitoring easier. Both perform identically for heat retention.

Heavy-duty covers (16-mil) are for long-term storage or harsh environments. Thermal covers add extra insulation layers. Solar rings are inflatable tubes that float around the pool’s perimeter, providing partial coverage at lower cost. Automatic covers with reel systems eliminate manual handling but cost significantly more.

Custom covers are made to fit unusual shapes and in-ground pools exactly. They cost more but ensure optimal contact with the water surface and maximum efficiency. Most residential pools use standard rectangular covers, which offer the best balance of cost and performance.

Case Study: Seasonal Pool Closing with Solar Cover

Background

A property owner in Illinois had an above-ground pool that sat dormant from October through May. The pool’s heating was expensive, chlorine consumption was high despite the cover being off-season, and algae was a persistent problem during spring reopening.

Project Overview

The owner purchased a 16 x 32 foot Aquabuddy 12-mil solar cover before the final swim of the season. The goal was to minimize chemical consumption during winter closure and speed up spring reopening through extended heating.

Implementation

The cover was deployed in late September, once water temperature dropped below 70 degrees and regular swimming use ended. A simple siphon was installed to remove standing water after rain. The cover was inspected weekly but removed only twice during the winter for equipment maintenance.

Results

Chlorine consumption during winter dropped by 60 percent compared to the prior year without a cover. Spring water clarity was excellent, suggesting algae growth was minimal even during off-season. When reopening occurred in May, the water was 8 degrees warmer than prior years, reducing the heating time needed to reach 78 degrees. The cover cost $250 and was expected to last 5 years, with total cost of $50 per year. The chemical and heating savings during that first year alone exceeded $200.
