Took long to arrive but worth it

These are really great panels. They produce plenty of watts even in cloudy conditions. I used these in winter and even in the morning before the sun was at its peak they were putting out nearly 220W. They pack quite flat. Downsides? The stands are a bit fiddly and the panels aren't super light.

It was on sale, so I got it to double my existing charging capability. I haven't had the opportunity to use this one, yet, but the original works great. On occasion, I have even exceeded the rated 220 watts. I just saw a review from Darren. He shows pictures. He may have a bad panel, but I can tell you that a good panel inside a screened enclosure with a thick shadow across the entire unit is definitely not going to work. Folks, there are thousands of YouTube videos and reviews with excellent information. Use them... The kick stand is an option. Especially if you are traveling a lot and don't have much space. For home or cottage, make a stand. Here is a pic with a couple of options. My sister made a sturdier one and added wheels so she could easily move her 400 watt panel around. I now have 4 panels and my Delta 2 Max charges very quickly.

I’ve only used my two 220w NextGen Bifacial solar panels a couple of times, but I’ve been very happy at the performance I’ve seen. I’ll start with my overall review of the product. These aren’t the smallest panels nor the largest, but I think they’re the sweet spot in terms of size, weight, and output. They can be easily carried by one person and fit into a car, SUV, or RV with relative ease. The case is nicely made and the zippers function smoothly, but I wish there were some sort of stiff material (thin plastic maybe?) in the sides of the case for a bit of protection, and an outside pocket for a solar power cable would be ideal. The panels themselves seem to be made of nice materials but we’ll see how they hold up over time. I’ll be using these for recreational and emergency power purposes, not everyday, so I expect they’ll last me a long time. My only other complaint about the panels is the lack of a built-in USB port like many other panels provide, which would be convenient. Overall, they seem to be made well, have built in stands that work (unlike the previous gen panel from what I’ve seen), and can be stored neatly in their nice carrying case. For testing, I hooked them up to my Delta 3 Plus, which has two solar inputs, so I could see how each panel performed individually. My quick tests consisted of setting them up on my partially shaded balcony and then on my paved driveway. The panels can be a little unwieldy until you get the hang of it. I find setting up the middle support first is easiest, then unfolding each side onto their respective stands afterward. In 40 degree February weather with no clouds here in the TN mountains, I got a total of 285 watts on my partially shaded balcony. Not too bad considering I didn’t have the space to really align them properly to the sun and one panel was constantly shaded by the handrail slats of the balcony. I’ve seen reviews that state some panels essentially lose all output when slightly shaded, so I wanted to test them in awful conditions to see what output I could get, and they still worked fairly well. Next, I wanted to test them in ideal conditions, so I moved to the driveway and took the time to align the panels to the sun using the built in guide, which is easy and convenient. Results? Consistently 390+ watts with frequent peaks up to 405 watts for 92% of the rated output! That could charge my Delta 3 plus from zero in just under 3 hours, and once charged could run a full size refrigerator and a couple of other small appliances without decreasing the battery level at all. This is my first foray into solar panels and generators, but I’ve been impressed with my ecoflow’s potential to provide power during outages and for recreational outings where power isn’t readily available.
