Ive been using this panel for a little over a month now. I really like to use things in multiple situations and gauge its effectiveness; This panel is perfect for what I am using it for. I wanted something that was lightweight, easy to store and transport to supplement my mounted solar panels. I don’t always have the best options for parking in the sun, and the angle is never perfect with mounted panels.
What I really wanted was a panel I could easily and quickly setup in the best location to supplement my charging. I have been extremely pleased with this purchase. It really filled the niche I needed with my setup in my camper van, and I also found myself using it in a lot of other applications because it is very portable and light weight.
1. Very portable.
I really liked how its all self contained, the cables, adapters, all come in a zipper pouch, and I ended up using it to store my 20 ft cables as well, so when it is time to set it up, its really a “Grab and go ” situation. The handles are very nice, and they have magnetic clasps so the unit stays closed until its time to use it. I really liked this feature, because it kept it safe, and stopped anything from slipping inside the panel when I was storing it.
The feet are velcro secured and right on the unit, its really nice that they secure so well, and they are always right there to use. That is one of my favorite things about this panel is that its all ” Self contained ” I do not need to look for feet, cables, or anything, because its all right there.
2. Well made
The construction is very sturdy, I’ve been using it for right around a month at this point and it still feels and looks new to me. Its very easy to clean/keep clean, the material is strong. I really love the zippered pockets and velcro hold downs for the feet. It keeps it all “Tight” and very quick to store and grab when I want to use it.
3. Comes with cable and adapters
I really liked how it came with extra cable length, and adapters for any device you might want to charge. I have some older power stations and was really surprised to be able to just directly charge those. It really made it easy to work it into my solar setup. It saved me money too.
4. Great power
Its a 100watt panel and I felt the output was very nice. Being so portable, it was very easy to set it up in the best location for the area I was set up in. I used an extra 20 ft cable I had as well, so it is always optimal. This really was clutch for me as it kept me from always being “Just about” there to fully charged on all my stuff. It is really perfect for my application.
Overall, I love this panel. It is so thin and lightweight, it just fits in a little niche I had for it like a glove. I have not had a single issue with this unit, and I cant imagine being without it anymore really. Just being able to add that extra wattage with the perfect output to my setup sent it to total perfection. Its just so nice how it folds in half and protects itself. I would really give this a try if you want something, Portable, well built, and effective.
Something else to add. I have been just grabbing this single panel and a power station for car trips and even a short hike. I really love the portability of this VS my massive fixed panels.

I’ve been using this panel for over three months at the time of this review. I wanted to list some features that I found beneficial as well as some observations based on my use. Do keep in mind that I have been using this panel every day and have been relying on it to provide 100% of my power needs (I live minimalistically.)
1. Lightweight and portable. ⭐️⭐️⭐️⭐️⭐️ • The ability to fold and store away the cable makes this panel convenient for an assortment of purposes, such as camping, off-grid living, beach days, traveling, etc. • The handles make it east to carry or attatch to a hiking pack.
2. Durability ⭐️⭐️⭐️⭐️⭐️ • The material of the panel itself is very flexible, scratch-resistent, water and weatherproof. • The fabric seems to be quite heavy-duty. I try to be careful with my belongings, but accidents can happen. This thing has been able to maintain resistance to scratches and tears quite nicely. • The handles are made of a hard plastic and does not seem brittle, despite being made in China. • I have yet to experience any issues with damage to the cable or connection of the cable to the panel.
3. Functionality ⭐️⭐️⭐️⭐️½ • As expected, due to energy loss from heat and other variable factors, you will likely not see a true 100w output. At least not for your average input. This is true for most solar panels, so just keep that in mind. • On a perfect day after a rainstorm when smog and other microparticles have been cleared from the atmosphere and the sun is shining bright, depending on other factors, you may see 80-100w. • These panels are monocrystalline, so they offer a higher rate of efficiency.
4. Customer support ⭐️⭐️⭐️⭐️⭐️ • Very satisfied with customer support. No problem at all communicating any issues with the order or the item.
5. Summary: Grecell may not be as well known yet as brands like Renogy or Jackery, however I was pleasantly surprised at how good of a value this product turned out to be. I was a little skeptical at first, but I’m glad to have stepped outside my comfort zone and try something different. My overall experience is going to have to be 5-star and I would definitely recommend this item for it’s price.

Although Amazon’s delivery could be better as there was a nice divot in the box, the solar panel itself was in perfect condition. It is easy to setup and very intuitive. It comes with a number of different connectors and adapters so, it is versatile as well. In my informal testing, the solar panels were inputting roughly 50-55 watts on an admittedly overcast California day. I used it briefly prior to in bright sunny weather and got anywhere from 80-90 watts in. Excellent!
The build quality is good and the tilt-back legs work fine. Personally, not a fan of the velcro keepers for the legs as I just get tired of the ripping flesh sound velcro makes. But, thats a personal thing, nothing against the Grecell itself. It is nice and slim and will easily fit in a tiny spot in the back of your car on your camp trip.
All in all, this is a great deal for those of us who are budget minded and don’t mind a relative newcomer to the market. As long as it works as advertised, I don’t care about the label on the front.
Only time will tell how these items will fair over the long haul. Lets hope it gives the big boys a run for their money!
