Just got these a few days ago and only brief test

Reviewed in the United States on May 19, 2024

These solar panels are pretty great so far. I’m not comfortable giving a perfect 5 stars until I get them out in the field for proper testing. UPDATE June ‘24: great performance out in the field! So happy with them. Upgraded to 5 stars

The carrying case is very durable material and the zippers look good quality (time will tell). The case is also used to hold the panels up at varying angles according to the sun position. One side of the case is solid to protect the panels and to enable the angled positions — good design choice. The overall size packed up is not too big and makes it quite portable. For basic testing, I connected this to my Bluetti EB3A (ordered the proper cable from Bluetti to go from Solar to DC7909..?) and set the panels up at a non-specific angle on my apartment balcony. Without trying to get the perfect angle and with some shading due to balcony railing and supports, I was getting ~85-90 Watts charging. May be a bit on the low side, and I’m hoping to see closer to 120-130 W when out in full sun and pointed directly at the sun. Will update after my next camping trip but only 4 stars until I get more data. The attached cables are good quality and were easy to connect to, but a bit difficult to disconnect from. But that may get better as I find a better way and get use to them. UPDATE June ‘24: was getting a whopping 136 W charging my BLUETTI with this panel out on a camping trip!! Great performance

I’m happy with the price to performance ratio, basic charging is good, and the case plus size make these quite versatile for car camping, beach trips, or even just a day trip where you need to power basic electronics. I do wish the panels’ power box where the cable came out had at least one USB port for quick connect charging of peripherals, but that’s not a need .. just a nice-to-have. Will update after more use and a chance to see if the charging stays stable or changes drastically over time.

Good power from a portable unit

Reviewed in the United States on December 8, 2023

I bought this panel along with an Ecoflow Delta Pro so that I could power my garage related appliances and electronics. I am currently running my garage refrigerator, a couple of battery maintainers for my cars and a motion activated light that comes on when I walk into the garage. The panels does a good job of charging my Delta Pro on most days and even charges a bit on hazy days, but of course not as much. It's winter time now and the sun is low in the horizon and shines fewer hours than in the summer so I'm thinking that I will be able to connect more things to it once summer rolls around. So far I am very pleased with its performance and I think it is only going to get better. The panel is portable but it does weigh a little bit due to its robust construction. I prefer that it is tougher and a bit heavier than lighter and flimsier, especially if it is going to moved about from place to place. It's not exactly cheap, but then you do get what you pay for and this is worth the price.

Very Good Stuff! Awesome Efficiency! Love The Portability & Ease of Installation

Reviewed in the United States on May 31, 2024

What I liked most about these panels is the efficiency. In peak sunlight I'm getting over 100 watts from the 160 watt rated panels, which is over 60% of the 160 watts, and that is without even having a 45 degree angle toward the sun, more like a 30 degree angle toward the sun at most times during my limited 4 hour morning charging period. May even get a second set to go with this one and double the power.

I'm running this with the ECOFLOW Delta Max 2000 2016 WH power station, which I'm also in love with. But like some of us newbies, I sometimes learn the hard way, like at first not paying complete attention and ordering some panels that are for the purpose of charging a car battery, but not a strong power station, and finding out painfully when the soon-to-be-returned 800 watt panels only put out a measly 25 watts max.

Not sure it’s all it c

Reviewed in the United States on July 22, 2022

I’m new to solar generators and solar panels. So my opinions are based on a first time user. I chose the 220 watt bifacial solar panel because is made sense to garnish extra power from the back scatter. I was anxious for it to arrive. I finally received it I couldn’t wait to try it out. Unboxing was simple with short instructions. Almost none on how to use the case to hold up the panel. I line in Central Texas and my trial was done around 1 pm on a very hot, 101 degrees at the time, cloudless sky. The sun was directly overhead so I laid the panel flat and plug it in to my new EcoFlow River Pro. I watched other YouTubers get 160 to 200 watts out of this panel so I was disappointed to find that I was only getting 107 watts. Perplexed, I tried many configurations and angles. Still I only got 197 watts. Thinking the panel was defective, I called the support number. She led me to turn on and off several features on the app. No success. She told me to continue to try different setups. So I posed my trouble to Amazon customers and Jeremy came through with the answer because he had the same issue. He told me to turn off “slow charging” and that would cure the problem. And it did. So I spent the rest of the afternoon moving the panel to keep it facing the sun at 90 degrees. The highest I reached was 170 watts. I don’t no if the extreme heat was affecting the output, but I can live with it. I did experiment with it though. Since the backside gets more efficient with higher reflective surfaces, I surmised that a reflective blanket was do the best. I used an Arcturus Heavy Duty Survival Blanket. It’s large, 5’x6’, and better built than others. I tried different configurations, panel sitting on it, hanging from the case with curve towards the panel and lying if front of the panel. I didn’t get any increase in wattage from any configuration with the reflective blanket behind the panels. I did get a 5 watt increase with the blanket lying in front of the panel. To make sure that the backside was working, I turned the panel upside down and it was putting out around 55 watts. I have no idea why I’m not getting of extra wattage that this panel was designed for. At least I’m getting adequate from from the 200 watt side.

Using the case to hold the panel works, but what a pain! After getting configured for the current sun position was fairly simple. But when it come time to move it, it helps greatly to have two or more hands. By yourself, expect the case to fall, get twisted, and take forever. My best solution was to anchor the bottom, non-rigid side. That helps tremendously. I’m looking for other methods besides that case. The case does simplify the amount of other equipment you have to bring to set the panels.

Overall, I think the panels and case work well and with the expense.
