WERCHTAY Solar Panel Monocrystalline 12V (120w Solar Panel)

This 120W Solar Panel works as advertised. I am new to the Solar world and I am learning as I go. I repurposed an old Satellite pole and mounted the panel to it. I am using it to charge my Bluetti EB3A. I use the Bluetti to run the heat tape on my main water line in a power outage. So far so good. Of course it depends on how much sun lite you have but on a sunny day I have had up to 90W input from the panel. This setup will keep my pipes from freezing when the power goes out. I will surely add another panel and expand the system in the near future. Great product. I highly recommend.

I liked the panel for its quality but when I went to use it the wattage coming into my solar generator was pretty low. I also purchased a 100 watt Renogy panel and it pulled in way more wattage after being in the same place as this this panel. Would not recommend this panel. 3 stars for build quality

Panel would not charge 12v sla battery in full sun. Seems defective but I was not able to return bc I needed to cut the connectors off so I could plug the cables into my charge controller . Should have tested it before installing.

Great product. Works great

Bought two panels to test fit for a project. Set them up just to see how well they did. At the 48th parallel, between 11am and 1pm on a sunny cloudless day. Couldn't get better then 66 watts out of each panel. Got barely over Half of what's rated. This is what you get for buying cheap panels. Do yourself a favor and buy better panels if you're doing more then just playing with them.

I bought a120 watts version. The maximum output that I got so far (under a bright sunny day in Northern California) is only 75 watts/hr. Getting 75 watts out of a 120 watts panel is only ~60% output efficiency. I was hoping this panel can produce more. Considering the panel's surface area is comparable to that of a typical 100 watts panel, this panel is working essentially as a mediocre 100 watts panel. Look elsewhere if you're looking for a solar panel that can produce more than 100 or even 90 wattages.

The most that I have gotten from this unit is between 68 and 74 in clear sky day during October. The temperature was between 47F and 58F.
