  • Great product, excellent supplier
Size: 6-4x10.5 (252 Square Feet)
Well made, high quality well packaged. Instructions and all the parts made it easy to install. The panel connector clamps require care when installing. I had 2 leaks and had to reclamp. My fault though so no complaints. 1 part was missing but an email to the supplier had that issue rectified immediately. I have not started using it yet, pool is being finished but I have every confidence it will heat the pool. After pressure testing it I dumped the water and it was as hot as bath water on a 60 deg day. All in all a great product and a customer focused supplier. Highly recommend. Update: Our pool is now complete and we started using the system. We regularly get the pool to 87 degrees and the hot tub to 102 degrees on solar only each day. We have a concrete inground pool in Utah at 5600 ft altitude. This solar panel system will pay for itself in the first year. We rarely use the gas heater now. ... show more

  • Works as advertised
Size: 3-4x12.5 (150 Square Feet)
Very easy to install. It took a total of around four hours. My pool water started out at 66° and in full sun for 6 hours on a 68° day my water temperature made it to 78°. The next day was cloudy but still got the water to 82° and we went swimming on a 68° April day

  • Assembly is difficult and the videos very misleading.
Size: 7-4x12.5 (350 Square Feet)
I am installing this alone and finding the install very nearly impossible. I have remodeled two homes, swapped car engines and built robots so I am a very capable do it yourselfer yet I am finding this impossible, I will likely return it. The videos make this look easy by cleverly not showing the difficult parts. First there is a note on all the boxes telling you to measure the panels before you unroll them, and threatening a restocking charge if they sent you the wrong items. They make no mention of how to measure them while still coiled. Getting these flattened is not easy, they have a lot of memory and try to recoil, you need to place one of the unopened crates on each end to keep them flat. I bought swim joy because I liked the way the panels joined together, in the video he makes it look easy, nothing could be farther from the truth. They have what they call an o-ring, it's not a normal round o-ring, it's very thin and has to fit deep inside two very narrow rings, alignment is very difficult, and it's hard to tell if it's right, then the fun starts, the clips barely fit without an o-ring and are very hard to assemble, compress and lock, I have yet to complete a single connection. Under the best of circumstances this would be difficult, but you have to fight the twelve foot long panel that snags on every shingle when you move up or sideways and slides down the roof with no provocation. The design is terrible and the video criminally misleading, even if the unit works great it will never earn more than one star. ... show more

  • Best panels anywhere.
Size: 4-4x10.5 (168 Square Feet)
The mounting and connecting system on the commercial line of their panels is by far the best ever. simple, easy, secure. And a HUGE nod to their customer service. I was missing some gaskets, and within two days I had them. and get this, an actual person answered the phone! I know, what a radical idea! I've used two other systems before, and one was so bad the tubes leaked upon the very first start-up. And I could never get any help with a replacement. Spend a few extra dollars and buy these. Your body will thank you for limiting your time on the roof. Especially when like here, it's 95 during the day. ... show more

  • As described, easy instructions.
Size: 4-4x7.5 (120 Square Feet)
Quick and easy install. Strait forward instructions, friendly and quick customer service for spare parts and additional panel. Purchased the 4 pack, still have time for one additional panel.

  • Easy install
Size: 5-4x12.5 (250 Square Feet)
I bought the 12.5' x 5 kit and it went together in a matter of hours with no leaks. My flat roof install was very easy single handed. Just lube the joints as directed and all fittings slide together no problem. The toughest part was hoisting it up to the roof, a bit awkward and heavy, but even that went OK with a rope and a sling. My last similar system lasted 20+ years so I have high expectations for this system. I have plenty of 70+° hot water coming from the panels for my 30,000gal pool in November. I live in San Diego so that is a big plus but these panels should extend your swimming season anywhere. ... show more

  • Heats the Pool Without a Gas Bill!
Size: 4-4x12.5 (200 Square Feet)
My husband and adult son installed the Solar kit on a free-standing AlumaWood patio cover. The patio cover is insulated to hold the weight of the Solar Pool Heating System with water in it. This is a great investment! It heats our large pool to almost 100 degrees if we let it. We cover the pool at night to keep the heat in. We are not using our natural resources to heat our pool and not paying the gas company, just using the Sun. So happy with this purchase! ... show more
