How to Choose the Right Solar Pool Cover

Start by matching the solar pool cover’s size and shape to your pool. A cover that fits well traps heat and reduces evaporation effectively.

Material thickness, measured in mil, affects durability and heat retention. Thicker covers, like 12 to 16 mil, last longer and retain more heat than thinner ones around 8 mil. Choose thicker if you want to extend your swimming season and reduce replacements.

Solar covers float on the water surface, absorbing and transferring heat. This makes floating solar heaters ideal for inground pools, as they conform to the pool shape and prevent heat loss.

For inflatable pools, pick a lightweight cover that fits snugly but is easy to remove. Thinner covers work well here because inflatable pools usually need less heat retention and the cover must not damage the pool material.

Look for covers that reduce water evaporation. This saves water and cuts down on pool chemical loss. Bubble designs with sealed air pockets are the most common and effective at this.

Ease of installation and maintenance matters. Covers should be simple to spread and remove. Some models come with reels or handles to make handling easier, especially for larger pools.

Sizing and Heat Output Considerations

  1. Measure Pool Dimensions
    Use a tape measure to get your pool’s length and width for rectangular pools, or diameter for round pools. Measure at the waterline for the best fit.
  2. Account for Pool Shape
    Round covers fit round pools best. Rectangular covers suit rectangular pools. Using the wrong shape reduces coverage and heat retention.
  3. Consider Cover Thickness
    Thicker covers (12 to 16 mil) hold heat better but can be heavier and harder to handle. Thinner covers (8 mil) are lighter but lose heat faster.
Avoid Incorrect Sizing
A cover too small leaves parts of the pool exposed, increasing heat loss and evaporation. A cover too large can be difficult to manage and may tear if it drags on sharp edges.

Running Costs and Energy Savings

A solar pool cover costs nothing to run once installed. It uses the sun’s energy to warm your pool and reduce heat loss. This makes it far cheaper than electric pool heaters, which draw power continuously.

Solar covers cut water evaporation by up to 95%. This means you spend less on refilling your pool and on chemicals lost to evaporation. One inch of water evaporated from a 20-by-40-foot pool equals about 5,000 gallons lost.

Electric heaters typically consume 5,000 to 15,000 watts when running. Using a solar cover can reduce heater runtime or eliminate it altogether, saving hundreds of dollars a month on electricity. For comparison, a 1,500-watt electric heater running 8 hours daily at $0.17 per kWh costs about $20.40 monthly.

Solar Pool Cover080.170.00
Monthly energy cost comparison with 8 hours daily use at $0.17 per kWh.

Solar pool covers typically last 3 to 7 years depending on material thickness and UV resistance. Thicker covers like the 16-mil VEVOR model last longer and resist tearing better. Their long lifespan spreads out the initial cost, making them a solid investment.

Use a solar cover whenever the pool is not in use to maximize savings. Removing it during storms and storing it correctly extends its life. The energy and water savings combined can cover the cover’s cost in a single season.

Safety and Certification Considerations

Solar pool covers are safe when made from UV-resistant materials that withstand sun exposure without degrading. Look for covers made from polyethylene or similar plastics rated for UV protection to avoid brittleness and breakage.

Safety certifications can indicate quality. Look for products certified by recognized bodies such as UL or ETL for durability and material safety. These certifications ensure the cover meets industry standards for performance and user safety.

Handle solar covers carefully to avoid tears and punctures. Remove debris before rolling or folding the cover to prevent damage. Store covers in a shaded, dry place when not in use to prolong lifespan and reduce fire risk.

Avoid Fire Hazards
Do not place solar covers near open flames or heat sources. Although made from plastic, some covers can ignite if exposed to direct flame or extreme heat.
  1. Inspect Regularly
    Check the cover for cracks or thinning spots that weaken its protective ability.
  2. Clean Gently
    Use mild soap and water to clean the cover; avoid harsh chemicals that degrade the material.
  3. Store Properly
    Roll or fold the cover loosely and keep it in a cool, shaded area away from sharp objects.

Are solar pool covers safe? Yes, when you choose UV-resistant materials and follow safe handling practices. Proper maintenance and storage prevent damage and reduce risks.

Certifications for solar pool covers are not mandatory but provide extra assurance. They confirm the cover’s compliance with safety and durability standards, helping you pick a reliable product.

Follow manufacturer instructions for use and storage. Avoid dragging the cover over rough surfaces to prevent rips. Keep children and pets off the cover to prevent accidents or damage.

Unique Features of Solar Pool Covers Often Overlooked

Solar pool covers offer more than just heat retention. They reduce chemical use by limiting evaporation, which slows the loss of chlorine and other pool chemicals. This means you add chemicals less often, saving money and reducing chemical exposure.

By cutting evaporation, solar covers also help conserve water. Pools lose thousands of gallons yearly to evaporation, especially in hot, dry climates. Covering the pool reduces this loss significantly, which benefits the environment and lowers your water bills.

Maintenance is straightforward with solar covers. They resist algae growth because sunlight penetration is reduced. Cleaning involves simply rinsing the cover with a hose and occasionally scrubbing with mild soap. This ease of care encourages regular use, which maximizes the cover’s benefits.

Environmental Impact
Using a solar pool cover can reduce water waste by thousands of gallons annually and cut chemical runoff that harms local ecosystems.
Good for
  • Reducing pool chemical consumption
  • Conserving water by minimizing evaporation
  • Low-maintenance cleaning and care
Not for
  • Covers can degrade if left on year-round without occasional removal
  • May require a reel or handling system for large pools

Frequently Asked Questions

What is the best solar pool cover for inflatable pools?
Choose a solar pool cover sized slightly larger than the inflatable pool to ensure full coverage. Lightweight, flexible covers work best for inflatable pools because they conform easily to the shape and can be removed without damage. Look for UV-resistant materials that withstand sun exposure and chlorine.
How much heat can a solar pool cover retain?
Solar pool covers can retain up to 70% of the heat your pool gains during the day by reducing evaporation and insulating the surface. The exact retention depends on the cover’s thickness and bubble size. Thicker covers with larger bubbles typically hold more heat but may be heavier to handle.
Can solar pool covers be used for any pool type?
Yes, solar pool covers are compatible with most pool types, including inground, above ground, and inflatable pools. The key is to choose the correct size and shape to fit your pool. Some covers are designed with reinforced edges or handles to suit specific pool styles.
What thickness of solar pool cover is best?
A thickness of 8 to 12 mils is generally best for balancing heat retention and ease of use. Thicker covers hold more heat and last longer but are heavier to remove and store. For smaller or inflatable pools, a thinner cover might be easier to manage.
How do I install a solar pool cover?
Spread the cover evenly over the pool surface with the bubble side down to trap heat. Align the cover edges with the pool edges, trimming excess if necessary. Use a reel or cover clips to secure the cover and make removal simple. Avoid wrinkles or air pockets that reduce efficiency.
What are the maintenance requirements for solar pool covers?
Rinse the cover regularly with fresh water to remove dirt and chemicals that degrade the material. Store the cover in a shaded area or cover reel when not in use to extend its life. Inspect for tears or thinning spots and repair or replace as needed to maintain heat retention.
