Update 8/25/2022:after 1 month of playing with these panels, I figured out a way to achieve better performance, is to serialize them as many as possible if your MPPT controller can accept higher voltage. Using 12V or 24V seems to always give low performance, not sure if it's due to current limitation from wire gauge or what.My initial setup was 24V with 10GA wire, I could only pull around 490-500W at most, no matter how I tried. I just tried 48V config yesterday and I was able to get 590W at peak, not ideal but better much than 490W from my point. :)Purchased 4 to put together a mini grid-tie system. MC4 connectors are super easy to work with. So far everything works as expected. Much lighter then the poly panels I bought a few years ago so can't complain :) Will put them all on the roof after rails and mounts arrive and I will definitely buy more if they are on sale again!This worked great, I am comparing it to a 100-watt folding panel, I used 2 of my solar generators. I am sorry I could not snap a photo of the screen they are just too dim to see in the sunlight, It definitely put power into my cheap generators. I did not use the 60-watt panels. The 100-watt panel was not far behind the large 200-watt one. I hope this helps someone out. I was very hesitant to purchase a solar panel without any reviews, but I am happy I took the leap, It will sit in my garage till I need it.I am very happy with this inexpensive solar panel. It matches my factory installed FURION panel perfectly and puts out about 2 more amps. Just installed it today, so can't speak to longevity, but I am currently very happy.Low wattage return. I would expect these to product closer to a 70-80% of their rated wattage, but they are closer to 45%.
