Great efficiency. Awesome design.
UPDATE:On a nice cold sunny day, probably the optimal condition, I was getting 488w all day long through my Segway Cube1000 mppt.I mean, it's just insane the kind of over wattage I'm getting on this panel.If you look around, Renogy makes a 400w portable that has the same design which cost almost the same price. And I know that panel isn't getting this type of over wattage from the reviews I've seen.I haven't been so impressed with any solar panel ever.(and I have a lot of panels.)Before picking this item, I though the price was a bit outrageous for 450w.Since this is a newer N-type 16bb solar panel with 25% efficiency. I had to get it and test them out.Let it be known I am a solar guy and my wife will even say it's an addiction.Being able to review such a high item item, I have to put this through a thorough testing.First impression. It's Big.The package is huge.After getting it out of the box, for a 450w panel, it's actually fairly light.Has a nice padded carrying bag with it.Came with just about every adapter and a 20ft? Extension MC4 cable.So far so good.Next, the design is just gorgeous.I have plenty of portable panels and none of them look like this.It's like a hybrid of the rigid and the older portable panel.All the corners have protective padding and the kickstand is easily the best.I also like the fact that the carrying handle is at the top and not on the side.One of the thing I hate the most able portable panels is setting them up, especially the whne they have 4 panels.It's just awkward trying to get each kickstand to stay still and laying them down.This new design is far away my favorite.You can hold the panel by the handle up top while you spread out the kickstand.And the kickstand stay still so you can lay it down.For how large this is, setting this up is far easily than my 4 panels 200w panel.Have I mentioned how gorgeous this panel looks.Now let's test this baby out.I was going to take out my solar multimeter and measure various readings but I had to just plug this in.It was an optimum bright sunny day in Florida.I used the power station that I knew had the best MPPT..Plugged it in and the wattage keep going up.It kept going and going till it got to uts rated 450w and it still kept on going.Wow just wow. Talk about a great first impression.If you know solar like I know solar, a good panel would like like 80% of its rating.85% and you're doing well. Only the great ones can sustain 90%.Just for comparison, I get around 70-75% on all my rigid panels.This one went past it's rated wattage.Yeah when the panels is cool, that's when you get the best reading.The real result is when you leave it in the sun for a while.I did that and it sustained 450w-455w. Still past it's rated 450w.Super impressive.Conclusion.About the price.Yeah it's new technology and new designs and it's priced like it.Portable panels have dipped below the $1 per wattage for a while now and this one is way above that.Why still 5 stars?You pay for new technologies. Just like when Tesla first came out.Now they can be cheaper than a gas car.This penl is the best of the best as far as portable panels go.Shaped and designed like a rigid panel but light and portable like a portable panel.Price has already dropped during black Fri just above the $1 per watt mark.They included a long MC4 extension cord which brings the price down even more.I'd imagine if you're a van life and you need a portable panel, this one is it.It will get you a steady 400w-450w and that's all you need.Just 1 portable panel gets the job done.If you need something less ZOUPW have smaller panels that are designed the same way.I'm a solar guy and I haven't been impressed with a solar product in a while.
