The output on these is pretty great. I've got 12 for my cabin and see close to 7k during the peak of the day in the summer. But the best part is how durable they are. Wind was 50 gusting 70 last week and it flipped 2 of them onto their face about 20 feet away on rocky ground. The mount was pretty beat up and just looking at my camera feed I was fearing they'd be broken. I was very relieved when I got up there and discovered they're still in tact, and the output is close to what it was. Really feel like I dodged a bullet there. Read more
I haven't actually installed these yet, but I did test them - surprisingly, they produced very close to the full 590w without any backlighting in late September. Haven't tested them on cloudy days yet, winter is when I really need them to produce. Read more
The weight of these panels are similar to the 550w panels, and the size is identical. And I got them for the same price! Good quality build from what I can tell. The frame is pretty standard, so install was no different than any other panel I have owned. Hoisting them up 15' to the roof was definitely a two person job. If you have rails (ladder) and some rope, that seems to be the best way. Also be cautious of the wind. While I was on a mostly flat roof, gusts up to 28mph made them want to fly away while I had them vertical. Once on the roof, they were ok. Power output so far has been right around 2100 watts for four panels. While they are on a roof mount now, I tested in the yard with a bit more back light to get those results (propped up with an extension ladder at about 15 degrees tilt). I did not put any reflective or white material behind them for testing like that. So far, they are producing more power than I use, so the battery is almost always at 100%. We'll see what happens when the mini split AC gets installed. Read more
They are the greatest! Read more
This product is NOT UL LISTED and my engineer won't even put them on permit application. Company refuses to take the panel back after a few months. Some of their products are listed so I guess there is a real problem getting these approved. Don't even think of using them in Florida or anywhere else your insurance company may ask for UL certified products. These systems produce high voltage Direct Current and fire and safety is a real issue. The company refused to take the product back or replace it with their UL listed product. Read more
These are very big, however, they are great and the packaging is impressive. Read more
These solar panels produce. Consistently delivering the rated output. I am not using them as bi-facial just as regular panels and they are fantastic. They stay consistent even when hot. The specs provided are spot on. Read more
