mudules = panels
for 6 panels it is a bad value!

I had today at 90°F DC=11350W, AC=10600W at peek at 13:16 with panels ratet 16575Wp.

So You should have: DC= 411W, AC=384W with panels ratet 600Wp.

I'd rather say something isn't measuring right instead of accepting 99% efficiency for those grid tie inverters ;)

yes indeed, there's nothing like testing cheap equipment with cheap tools, the troubleshooting continues... I have also ordered some Rich Solar solar panels and will do a comparison test using just them


a video of a dude troubleshooting a Windy Nation solar panel [surprise]

well call me crazy but I don't see no Yoda in there

FYI, this is the 7th panel, I will call this Panel #0 as it was not on the patio cover at the moment but I decided to check its black box for blown Da Yodes first just because it was easy to get to (no roof climbing needed) I believe this was the very first panel I ever bought, knowing less than zero about solar panels

are you telling me that the reason Windy Nation solar panels are the cheapest on AMAZON is cause Windy Nation is skimpin' on diaodes ???

this beauty will be coming to Facebook Market Place near you real soon

time to Science the crap out of these WindyNation cheap solar panels, so first of all because I was buying these panels during the pandemic, the same vendor would sell them under the same exact part number yet not all three are the same, the first one is different from the other two (Great!) but the last two are identical

so decided to give a different brand of solar panels a go, and picked up a pair of these Rich Solar ones still for under $100 a panel, two for $186

I am not one big on unboxing videos or evaluations but sometimes you can judge a book by it's cover, and these came well protected, well done Mr. Solar, also preliminary tests of a single panel shows it peaking just slightly above 80 watts, that is more better than the 50 or so of the Windy Nation crap

more testing today, going to connect both panels and see what they pull or capture or what ever you call it
