150W Bendable Monocrystalline Solar Panel

I bought 6 x 150W panel because they had a nice geometry and would fit on the roof of my boat. So theoretically: 900W. I did two groups of three, so a 60V system. The most I could ever got out of it was around 650W (California coast, clear sky, noon). After two months of usage the max power is 270 W (!) (3 panels do 60W, 3 panels to 30W, measured them individually). I had to replace them all with a different product which now works like expected.

The film started peeling off and the cover box cracked ok as a temp use but go for the better product if looking for long term product

So far so good. I was able to put it in series and parallel with another brand solar panel that I had and it worked will in both configurations. Has sufficiently long MC4 connectors. When connecting to a power station by themselves I was able to get 130W on a sunny winter day in full sun. Can't complain about that. I will note, that I got another brand solar panel, that seemed to do great at first. I had it in parallel and I was over paneling so I didn't notice the out put decline. But the other flexible panel is only giving me half of its original output after 6 months. I have since learned that flexible panels cannot just lay flat on the surface because they can over heat and get damaged. You must add spacers on the bottom so air can flow and cool them down. I suspect this is what happened to the other panel I had that seems pretty much identical to this one. No doubt they were just the same panel rebranded.

Barely worked when brand new out of the box. Shame on me not replacing it right away. Took it on a 10 day trip and it had completely failed to near zero output by day 3. Left me stranded every day with zero output. You get what you pay for. This is trash

Seems like almost all of these panels are over rated for the output on here. So I went 150w with a target of 100w. That was right on, hit 98-108w with a perfect clear Colorado sky at 6k elevation pointing directly at the sun. The seal on the output are seems a little lacking also, may need a little more coating down the road.

The Atem Power 150W Flexible Solar Panel is light and well built, comparable to other flexible panels. The hard, flexible plastic outer casing of the panel is very durable. I did not test the extreme flexibility claimed in the ad, since I have no need for this level of flex. One reviewer spoke of the panel crackling when warm. It's winter here, but I have not seen any tendency to crackle. I would describe this panel as robust. I have read comments that the junction box has cracks at the wire entry points. I have seen no evidence that. The construction looks a little haphazard because of the way that the sealant was allowed to ooze out and congeal, but I would rather have too much sealant than not enough. Note the cosmetic flaw of the manufacturer's label crudely applied. These items detract from the appeal of this panel, but do not affect the function, which I would call comparable to other panes in it's class (I'm not a rating agency, but I do have two other flexible panels of a different brand and several folding portable panels. It bothers me when the specifications listed on the Amazon sales page differ from the official specifications found on the product. I have included a picture of the official specifications sheet attached to the panel. Compare the voltages and amperages on this placard to the official looking specifications list on the sales page. I believe that they were looking at the wrong panel. 4 stars for cosmetic issues and inaccurate advertising on Amazon. But a good serviceable panel for permanent mounting or portable use when your panel does not need to be folded up small for storage.

Two 150w panels in series rarely see over 200w in perfect conditions.

Spent hours installing these to do a nice roof install on my Super-C RV. Had high hopes and they worked for less than a month. Now too late to return and no support available. Don't buy these or any of them branded as these. I'm more upset at all the time and work I put in to install them than the crappy panels failing.
