    Decent Panel for the Price

    Decent Panel for the Price
    Initial review: Panel is decent quality for the price. $0.75/watt is a great price. Open circuit voltage was around 21.89VDC on a very sunny clear day, so close to advertised. Test was Northeast, North America. No test under load yet as charge controller did not ship on time. I have attached a photo of the internal lamination issues but other wise the panel is still a good buy. Also, included a photo of the specifications for the panel, which was omitted by the Amazon seller. Panel is manufactured in Indonesia. Overall, I still would buy again. I will try to post an updated review once load is connected.

    5.0 out of 5 stars These panels are tough!
    Reviewed in the United States on February 6, 2018
    100 Watt 12-18v solar panel: The panel arrived quickly, but there was an obvious penetration to the packaging. Upon opening the package, I discovered a pretty significant dent in the aluminum panel. No cracks in the glass or cells, but I was concerned. I needed this panel for the weekend. I tested it quickly with my meter and it appeared fully functional. After setting it up, it was charging my battery bank and working great! So, I can tell you that these are some tough panels, this one took a beating and still performed. Yes I wish it was not dented, but that is really the delivery carrier's fault, as the panel was packaged very well. Very happy with seller!
