Features 5

  • HIGH-HEAT PERFORMANCE - SwimEasy solar pool heaters capture more heat from the sun with superior absorber technology. They also enable water to move effectively through the collector by removing flow barriers with its specially crafted over-molded header. These features combine to give SwimEasy solar pool heater panels extreme heating capabilities!
  • SUPERIOR HEAT TRANSFER SwimEasys manifold is molded directly around the absorber tubes, eliminating flow barriers and allowing water to freely exit the manifold into each absorber tube. Flow is one of the most important elements to a solar pool heater. The water flowing through the system is what transfers heat from the collector to your pool. The more water that flows through your panels, the more heat thats transferred to your pool.
  • EXTREME DURABILITY - SwimEasy solar pool heaters are manufactured in the US with high-grade materials and specialized U.V. stabilizers. SwimEasy solar pool heaters are built to withstand your rooftops extremely harsh conditions, in all types of weather, for 15-20 years!
  • QUALITY FROM START TO FINISH - SwimEasy solar pool heaters use todays most advanced technology to create a single-piece header. The result is a solid, one-piece panel with virtually no manufacturing variances. Solar pool heaters undergo tremendous stressors over the years, so the bond between the headers and riser tubes is extremely important for assuring leak-free operation for years to come!

Description

EACH DIY KIT INCLUDES EVERYTHING YOU NEED TO: Install the selected number of solar panels in a single row. Mount each solar panel to your preferred installation surface (roof or rack). Make water connections to and from each panel. Make water connections to the systems’ supply and return plumbing lines. Contains the parts necessary to aid in gravity drainage of the panels and piping. THE FOLLOWING COMPONENTS ARE INCLUDED IN EACH DIY KIT: Panel Kit: Contains the parts necessary for installing a solar pool panel to a supporting surface and making water connections from one panel to another. Row Kit: Contains the parts necessary for making water connections from a row of solar pool heating panels to the systems supply and return plumbing lines. Also contains the parts necessary to aid in gravity drainage of the panels and piping. Hold-Down Strap: Fastens solar pool panels to a supporting surface (roof or rack). HOW MANY PANELS DO I NEED? The most relevant aspect of sizing a solar pool heating system is based on the surface area of your swimming pool (measured in square feet). We recommend matching 50%-100% of your pools total surface area to solar panels (total square feet of solar panels). *For example, if your pool has a total surface area of 500 square feet, then 50% solar coverage equals 250 square feet of solar panels / 75% solar coverage equals 375 square feet of solar panels. From this point, you'll want to look at selecting a panel size that fits your installation area. Higher percentages of solar coverage equate to longer swimming seasons.

Quality product. Expensive but worth the money.
Size: 2-4x10 (2" Header)
Great customer service. We purchased a less expensive product that failed right out of the box. So we were really pleased with the quality of this one.

Easy to assemble.
Size: 5-4x12 (2" Header)
Can't say I was happy with the price. But if it last as long as predicted I'm extatic with it! Once I read a thoroughly understood the installation instructions it went together easily. I bought this to replace an old failing system and it's working great. My pool size is 16'×42' and the 5 sections have it up to 83. ... show more

Watch Out When Mixing with Older Panels from SolarPoolSupply
Size: 2-4x8 (2" Header)
I replaced a panel in 2021 in a row of three panels with a Solar Pool Supply panel. Now, in 2025, I needed to replace the other two panels. I assumed that ordering the same panel from the same supplier would give me an exact match. Unfortunately, according to the very helpful customer service guy at Solar Pool Supply, they switched manufacturers and the connectors on the panels are a bit shorter. I was sent rubber panel connectors that worked with the new panels but were too short to connect with the older model. The helpful customer service guy sent me the 4" rubber connectors that would work for me. The picture for the product shows the panel connectors for the old model, so Solar Pool Supply would be well served by updating this picture. Had the picture been updated, I might have caught this problem before demoing the old panels on the roof. Also, note that the new connectors don't have a mid-connector ridge/stop point that is described in videos from Solar Pool Supply. Also, this product comes with 8 strap nuts that are also not shown in the main picture for the product. ... show more

Nice Product
Size: 4-4x10 (2" Header)
My old solar panels lasted 30 years. They finally started to have problems. Springing leaks. These panels are almost exact duplicates. They connect right up. I got the connection kits and tie downs. I have the panels on a raised frame but the tie downs still did their job. Panels arrived in two days. I let them uncurl for a couple days and the replacement went smooth. It’s no fun to fight curled up panels. These seem to be pretty robust panels from the look and feel. I hope to get many years of trouble free operation from them. Good service, shipping and product. I’m 74 years old so I enlisted the help of my son to assist in the install and it all went smoothly. ... show more

Quality product, very strong customer service
Size: 4-4x12 (2" Header)
Product appears quality, all the parts fit well and work as designed. I am impressed with the system compared to a previous one I had that finally gave up. When shipped one little part was missing, an email quickly got a response and the part on a FedEx shipment. Came in in a couple days, just as I needed it. Another call to Solar Supply to get clarification was immediately successful. Appears to be a quality product sold by a quality, well managed, company. ... show more

Failure system
Size: 8-4x10 (1.5" Header)
This system doesn’t work. It’s unsuccessful and needs high temperature to work, so I don’t recommend this system, and I wanted to return this system they didn’t accept because they know their failure.

Great value
Size: 10-4x10 (2" Header)
They come to box roll tightly plan to let them lay out in the sun for several days to straighten out before you try to install. Appear to be high-quality but time will tell.
