12 customers mention2 positive10 negative

Customers are dissatisfied with the flow of the solar panel. They say that the water wouldn't circulate correctly, it was almost like the water was not following through all of the tubing. They also say that it restricts water flow and slows it down. Customers also mention that the pump had a low flow warning, and the flow was poor with two panels connected.

Real world performance of four panels on an 18’ Pool
4 Stars
Real world performance of four panels on an 18’ Pool
Four of these panels in sunlight for about 7 hrs raised our 18’x52" Intex round pool (6900) gallons from 64 to 71F. This is about 70 000BTU/hr. We have a fully treed lot so the pool is shaded all day, and the panels see good sun from 11:30 to 6:30. This pool is shaded most of the day, so the temperature increase is 95% from the panels. This is a roof top installation with the panels plumbed in parallel. I’ve also connected each panel so that the flow is now fully parallel, which keeps temperature increase across the system at 4F but with very high flow for better efficiency. The Intex 1600gph pool pump is able to push the water up 1 story without issues, however flow was poor with two panels connected as per the instructions. Flow is much better with two inputs at one side of the panel and returns at the other end. You need to plumb this setup yourself. “Game” makes an adapter kit GAME 4560 40mm to 1 1/2 Inch Conversion Kit (For Intex & Bestway Pools)to take the Intex 40mm connection hoses to standard 1 1/2” thread PVC so you can plumb these panels with 1 1/2 PVC or ABS pipe.Updated for 2019: We added two more of these panels, for a total of six as our pool is almost completely shaded. You can view the live data here for the pool and sensors: https://www.hundredgraphs.com/dashboard/denwoodI also discovered you can remove the restriction plug (it's just a spring clip plug) on the intake side of the panels (look down into the intake pipe) using an 18" long auger bit (1/2" or 3/4" will do). Just give it a few turns and pull. This does not damage the panels at all...just removes the plug. This makes it much easier to just have intake at one end of the panel, and return (warm water) at the other. This is 100% required to make this panels work efficiently without killing your pump flow. We were seeing about 400 000 to 450 000 BTU input from four panels per day. Will report back on the six panel output.

5.0 out of 5 stars definitely works
Reviewed in the United States on June 4, 2019
Within a few days and full sun it raised the pool from 65F to 80F (22'x52'' Pool with 10500 gallons). I am also using a solar blanket over night and during the day when the pool is not in use. I spent about $200 on wood frame and 1.5" pvc piping to feed and bypass the system. I added extra couplings for adjustments and easy take down for Winter. I even painted the PVC piping black to get every piece of energy....I feed it from the bottom corner on one end and take it out the upper corner on the other end (panels in parallel). I use threaded pvc couplers to attach the pvc piping to the panel. I did not use the provided couplers as they seem to reduce the flow more. I use a 14" intex sandfilter pump (2,800 GPH). A little increase in pump pressure and less flow into the pool when going through the panels (I also use an intex auto pool cleaner and it only really works when bypassing the panels). I wonder if a 3rd panel in parallel would help with getting the flow rate back up. I have some minor leaks (droplets of water from some of the little pipes) and I am waiting for a replacement (still give it 5 stars as exchange was a breeze with Amazon and they let me keep the old one until the new one arrives). Leaks are so little I can still run the system but for the price I expect absolutely no leaks. It comes tightly rolled up so I would recommend to let it sit in the sun and let it unroll/flatten itself.
Overall it's a great system. It requires some space but this kind of heating system is all about surface area.

5.0 out of 5 stars 24' round x 50" deep Intex pool in mostly shaded back yard heated at least 10 degrees!
Reviewed in the United States on July 3, 2019
Last night after the sun went down we were in our 88 degree water with visible steam rising from the surface. It was awesome. The average daily temp in PA where I live has been less than 70 degrees since we filled the pool and about 78 the past 4 days. Last year I might have been able to get the water temperature up to 78 this week had I been very meticulous with the solar cover. So I'm crediting these solar panels with a 10 degree improvement.

The panels were actually the least expensive part of the project. All together I spent about $1000 for this set up, but I had a lot of fun doing it. My house is too far away from the pool to run pipe through the yard and up to the roof. The pool gets only about 4-5 hours of sunlight a day, but the area around the pool gets up to 9 hours of sunlight per day. The problem is this: the area with sun changes from the west side of the pool to the east throughout the day. So how can I capture sun all day long for heating purposes? Build a "roof with wheels"! Despite being 20' long, I can easily wheel this thing around by myself. The solar panels are connected to the pool with 1-1/4 flexible sump pump pipe. I originally T-ed this into my filter pump, but I found that trying to run it using the same pump as the filter created too much resistance for the filter to effectively clean the pool; so I purchased a separate 1.5 hp pump just for the heating system I also created a separate outlet and inlet for this system so that I could pull colder water from the top of the pool and push warm water in toward the bottom ( on opposite sides of the pool).

It might seem complicated, but it really works well, and we've got it down to one move of the panels per day at about 1pm. If you can put these somewhere that the get sun most of the time, and provide sufficient throughput, you will not be disappointed!
