So, you’re interested in solar products for your pool, huh? Awesome. We’re big fans of solar here at LinerWorld and love to tout the benefits to our customers. However, figuring out what’s right for your pool and if they’re really worth the investment can be a challenge. To help set you on the right track, we’ve compiled some frequently asked questions from our customers about solar pool products and shared some of our top tips and tricks. Read on to learn more about solar heat panels, solar pool water heaters, and more.

What are the benefits of using solar for your pool?

Solar Dome Pool Water HeaterThis is a great question and one we get asked a lot. There’s nothing better than using what’s already right in front of you, and harnessing the power of the sun is a great option both for the environment and your pocketbook. Here are just a few of the benefits our customers experience after purchasing solar covers, panels, or heaters for their above ground swimming pool.

  • Save money due to a dramatic reduction in pool heating costs
  • Natural and environmentally-friendly heating option
  • Can extend your pool season by allowing you to open your pool earlier and close later
  • Solar pool ionizers and solar pool covers can help keep your water cleaner and reduce chemical use
  • Solar pool covers can reduce water evaporation by up to 95%
  • Solar products work with almost all above ground swimming pools

Solar products are really expensive, right?

That’s a myth. Sure, the initial cost of purchasing a solar swimming pool heater, solar cover, or solar panels for your pool may be slightly higher than a comparable non-solar option, but the long term cost-savings are going to put you ahead. Solar products can last much longer and, because they use the sun’s natural energy, they don’t have any additional operational costs. As noted above, you’ll also see reductions in your pool heating costs overall and likely be able to enjoy a longer swimming season, which ultimately makes it a worthwhile investment. Most pool experts note that solar products tend to recoup costs and pay for themselves in about 2-3 years.

How much money can I save with solar pool products?

There’s no doubt that keeping a swimming pool clean and warm takes a lot of electricity, which can, in turn, cost you a lot of money. That’s where solar products come in. We see solar panels, solar pool heaters, solar pool covers, and other solar products save homeowners hundreds, if not thousands, of dollars each year. How much money you save depends on where you live, weather, and other factors.

That being said, here are a few examples of how utilizing solar products in your pool can impact your average costs.

  • According to, heating your pool using solar saved pool owners between $87 and $121 per month (depending on location), which can add up to thousands over the course of your pool’s lifetime.
  • According to, heating a pool with gas can cost homeowners between $4 to $17 per hour, whereas solar drops the price to between $0.18 and $0.26 per hour.

How long do solar pool heaters last?

Great question. Most polypropylene solar heater panels, like the ones we sell at LinerWorld, will last at least 10 years. In more moderate climates where the sun takes less of a toll, they can last even longer. Of course, proper care and maintenance will play a role in how long your solar panels or heater will last.

Are solar products right for my pool and yard?

Above Ground Swimming Pool Solar CoverBefore committing to solar products, like heat panels, it’s important to take a good look at your backyard, pool, and patio area. Not all yards or pools are good candidates for solar products. The efficiency of solar obviously depends on how much of the sun’s energy is able to reach your pool. Here are a few things to consider to determine if heating your pool using solar products is a good option:

  • Solar works well in unshaded areas. Trees, shrubs, and shadows from buildings can impact effectiveness.  
  • Conventional wisdom is that solar panels should generally face south for best sun exposure.
  • Depending on where you live, you should consider local building regulations, HOA rules, lease agreements, and other legalities that may impact installing solar panels or other solar pool products.
  • Measure the space available, particularly for solar panels. Our solar heat panel measures 2’ x 20’ and multiple panels may be necessary depending on the size of your pool. Make sure your yard has adequate space.
  • Solar products can still work in colder climates with more clouds and precipitation, but generally, they’re going to be most efficient in hot, sunny areas.
  • Fences and hedges can be positives. They can help block wind and other weather to increase the solar panel or heater’s effectiveness and protect against damage.

How many solar panels do I need to heat my pool?

As noted above, the solar panels we sell at LinerWorld are 2’ x 20’, which is approximately 40 square feet. This is a pretty common size. Use the following guide to help you determine how many you’d need to heat your pool efficiently.

How do solar panels work?

How Solar Panels Work - LinerWorld

While it may vary slightly depending on your pool and the panels you select, solar panels generally work like this:

  • Water is pumped through the filter.
  • It then goes through the solar collector(s), where it is heated by the sun.
  • The warmed water is then returned to the pool.

Some systems use a control valve that helps direct water through the solar collector.

The process is actually relatively simple.

  • The pool water is fed into the heater by the pump
  • The sun heats the water as it circulates through the heater
  • The warm water is then returned to the pool.

Will solar panels or heaters impact my pool chemistry?

No, not if they are installed and working properly. That being said, having a warmer pool means you may be swimming in it more, which in turn means you may need to adjust your chemical usage accordingly. In addition, solar pool covers, and pool covers, in general, will help keep debris out of your pool and keep it cleaner longer as well.

Solar installation and maintenance tips

The solar pool products we sell at LinerWorld are fairly easy to install and maintain. However, it’s important to keep safety in mind when doing any pool maintenance. Here are a few general tips

  • Always read your owner’s manual and follow instructions as noted.
  • Clean all solar products regularly for the best results.
  • Store solar covers, heaters, and panels in a safe, dry location during the winter months.
  • When using a solar cover for the first time, leave the cover floating on your pool for 2-4 days to help remove the packaging creases.
  • When you install the solar cover, the bubble side should be facing down.
  • If you’ve recently shocked your pool, wait at least 12 hours before installing your solar cover, heater, or panel. The chemicals may cause damage and void your warranty.
  • As with any pool accessory, solar products are going to work best when your pool water is balanced.
