So far the panels are doing their job as they were intended. I'm happy with them and the price was good.

UPDATE: First purchase was 11/22/24: Today is 01/06/25: I've been using two of these panels for about 4-6 weeks. Normally, they keep my Acemo topped off, but the last two days were cloudy, and I discovered this morning that I had a bad wire connecting to the panels. It is currently 4:30PM and the sun is well over the other side of the apartment leaving the panels in the shade pointed away from the sun. You can see the reflection of the sun in the clouds. If I backed up, the sun would be just below the clouds on the right. Even in the shade, the two panels are charging the Acemo at 25 watts, now that I replaced the wires. I often get 30-35 watts in the shade, but I'm not getting much reflection today. During the morning when the sun is shining on the panels, I get up to 135-140 watts. When I mount them on the roof below them, they will get more light while the sun is overhead, and during the summer, they will get a whole lot more sun, for several more hours a day. The online calculator for this area says the best I can hope for is 60-65% of the panel's ratings, so 50% is the most I had hoped for and I'm over that mark. I currently only power a few things on the Acemo to keep it exercised. It's primary purpose is to provide power when the grid goes down. With 4 panels, I hope to remove my computer station and lights entirely from the grid. I have them, I may as well use them. My original plan was to hinge two of these panels together for a portable array, but they are really too heavy to port around easily, so I'm going to leave them mounted to the low roof and power my apartment as much as they can. I've seen complaints that someone received different panels when he ordered at different times. I ordered one single, later one pair, and most recently, one more single. I can't tell the difference between any of the panels. so I have not had that issue. The input to my Acemo is just shy of allowing me to use two panels in series. That's ashamed, because I would love to pair them up instead of running all of them parallel. The bathroom scale says that each panel weighs 14.4 pounds. Original Review: I now have 3 of these panels. The first one is in the window and the two new ones are #1 and #2 in the first picture. I was getting 83 watts of charging into my power station compared to 30 watts from 50w panel #3 and 70w from 100w panel #4. They weigh 14.2 pounds by my scale, but the other panels did not reach the minimum measurable weight on my personal scale. The two yard sticks are in the pictures for anyone wanting to compare sizes. For this time of year, 83w is about the most one would expect to get at this latitude this time of year. It probably helps a bit that the temperature outside was only 32 degrees when I got that reading. The wall you see the panel laying against is facing east. In the afternoon to evening, it is in the shade. During mid-afternoon, it was still charging at 25-30%. Of course, when the power station hit 100%, it quit charging. I read some of the negative reviews and they complain about low power and a weak frame. It's hard to know why someone had low power. There are a lot of factors to consider. As for the weak frame, these panels do seem heavy for such a thin aluminum frame. Panels 3 and 4 have the same frame material thickness as this one does. This one seems much heavier. Right now, I am satisfied with my purchase and I am especially happy with the price.

These were the most cost effective solar panels available on Amazon I think. That may be different when you read this but currently I think it's the case. I bought 4 during covid, then bought another 4 recently. They are all rated for 100 Watts, with a very small difference in open circuit voltage. All panels checked out and landed within open circuit voltage listed on the panels. Connected with 15 foot bougerv solar wires and connectors into 2 MPPT controllers. Wired in series I believe. Can't remember right now. With properly rated wire between the controllers and the battery, we are still getting 5 - 600 watts out of this setup, max. I expected much closer to 800. We are going to try a series/parallel setup next to see if we can get closer to the 100 watt value of each panel. I'm not disappointed with them. They are cheap solar panels. If you have a premium of space - buy nicer ones. I knocked off a star for the lackluster performance. I will come back later if the series/parallel setup proves out to be much more efficient but I doubt it. That being said - they didn't come with mounting brackets so figure that into your cost. They are very light but seem well made. I have no complaints at this time, based on my expectations. It's just that under load they don't perform at 100 watts with my specific setup. Install was done with an electrical engineer, so I have no doubts they are properly wired up.

5/3/2025 - Just installed and everything test good. Great power output. I can't give specifics because I'm running this one in parallel with a Grape Solar 100W panel that is 4 years old and I got combined output from the two at least 150W before clouds arrived. I mounted these onto my roof with Unistrut rails and these hold-down clamps (https://www.amazon.com/dp/B0DQL39VTV). Very impressed so far. If mounting on a camper/van, I would not mount directly through the thin aluminum frame holes. Use more robust solar panel clamps like above and ensure those clamps are near the front of the panel to reduce potential for wind to lift the front and break the panel. For normal use, the frame is certainly strong enough.

Bought 4 panels, mounted them on the roof of my camper. I used Z brackets, to mount them parallel with the roof. Wired them 2S2P and I use them with 4-100AH LifePo4 batteries, through a 100V-60A controller. Haven't had to use my generator at all, since installing them.

HQST used to make really good panels but now I'm not for sure anymore. The panel size I ordered 3 years ago was 40.03"x20.07" which used to be the norm back then, now it's a totally different size. I absolutely loved these panels, because my voltage on a 12v panel was anywhere from 21.78 to 22.04 volts per panel and was amazing to get so much power out of them. With 9 panels wired in series I was getting 198 to 203 volts just on 1 array of panels on a 72 volt system. Unfortunately, my lawn mower hit a rock that I didn't see and it destroyed one of the panels and I can't get the correct size replacement for it. I've be searching for over 2 weeks trying to find a replacement panel with no luck. When I first installed the panels 3 years ago, I spent days making the locking and sealing mechanics to lock the panels in so if one of the panels became damaged, I could unlock it from the mount and install a replacement in less then 3 minutes, but I can't because they don't make that size anymore. So I'm extremely mad at HQST. If you make good product, keeping making it and don't change it.
