DOKIO 100W 18V Flexible Solar Panel Monocrystalline for 12V Battery Charging, Semi-Flexible ETFE Lightweight with MC4 for RV Marine Boat Camper Van Trailer Off-Grid Power

While these were intended for attaching to the roof of an RV or camper, I was replacing 12-year-old glass panel sets, 3 on my side porch roof and 2 "portable" (yeah, they could be moved around but were HEAVY) ones in my front yard (that's where the sun is). Therefore, there really wasn't anything to glue them to. Instead, I used PVC pipes and built frames for them, attaching them to the frames with plastic wire ties. I bought 4 of these panels and built 2 frames, each frame to hold 2 panels. See attached photo of first finished frame. They weigh so little even with the PVC pipe frames that I can pick up and carry both frames with ONE HAND. I use them both in the front yard and store them in the garage overnight to prevent theft (light weight makes them easy to steal, too!) and so they're not knocked over by the wind. BTW, being knocked over doesn't break them like the old glass ones. They are also pumping out a great deal of power, so much so that there's no need to put any on the side porch. These 4 panels plus 2 more on order for a third frame all in the front yard during the day give me more power than I expected. Even in hazy sun they produced 22.4 amps at 12-14 volts. With clear skies it's 18-19 amps. With the 3rd frame I expect to get near the 30 amp max my charge controller can take. The batteries will stay charged and I can run the refrigerator all day plus electronics. Sweet!

I purchased 10 of the 100 watt solar panels I was highly skeptical at first and was about to return them all because they were barely getting 45 watts but it was pretty cloudy. I have a 50 watt foldable panel that will get that wattage in clouds AND rain but I decided to hold off and give them a full sun test since my primary need is going to be during sunny weather. BEST DECISION EVER! These things don't look like much but they are believe me!. 9 out of the 10 got mid 90s wattage except the one I used in the stat test video. It got 87 watts. But today it got 90. They're extremely lightweight & way more flexible than I expected them to be. Honestly for the $59 a piece I paid I am extremely happy with the purchase. Definitely great value for the money. I bought 10 thinking I was going to need that many to run my 1,200 watt inverter to run my window AC in my van but ONE of them kept the battery charged and my AC running all day. I will say this though these things will shoot up in the voltage and FAST so if you have sensitive inverters or appliance be sure to regulate with the charge controller. I set a calendar reminder to do an update at the end of summer which in Texas in long but if they survive this sun here then they'll pretty much survive ANYTHING!!

I needed something lightweight for my solar generator in an apartment building and this fit the bill. I made a frame out of PVC and attached it with zip ties. I probably have to pull it in on windy days I got 87 watts on a sunny day but I'm sure I could find tune the angle to get better.. My only complaint is I wish the panels had more more mounting holes. I made some on my own in spots that were free

This is a very disappointing product. There are not enough mounting holes to stabilize the panel properly. The holes on it are in the corners, very close to the edge and the grommets are flimsy and will break with any panel flex. The glue that holds the diodes to the panel is relatively useless. The panel worked for the day I had it and it literally fell apart piece by piece. It worked perfectly while in one piece but that lasted 24hrs. I'm so disappointed with this product I can't express it in words. The only application I could see this panel being used for is camping where you can just lay it out and let it be. Not good for RV or Boat or any hanging application unless it is fully framed.

attached to my camper roof with butyl rubber tape, one across the leading wind edge, the other 3 lengthwise, one on each side and one down the middle. non- wind edge i left for some breathing. went around the wind edge with some wide RV vinyl tape on the leading edge again just covering edge of the panel, making sure not to cover the solar. Also did this on the sides and left the back side open again for some air to get under. Stayed on great and will be purchasing a 3rd for 300W capacity. Going to run a outdoor fridge and margarita maker!

These flexible solar panels have proved to be perfect for installation on canvas-topped yacht flybridges. In our installation, 2 100W panels are providing plenty of daily standby power for long term maintenance of our 900AHr house battery system, without having to plug into marina dock power.

Does not produce as much as advertised compared to some other panels that I purchased at the same time although the seller did lower the price to match it's performance and quality. Must be mounted to something solid without alot of curves just slight transitions I glued this to a RV with a removable flexable 3M marine 4200 glue.

So far, I have purchased 7 x 100w solar panels and 1 x 300w portable solar panel kit and all are good, solid products. The portable kit, the material holding the panels is showing deterioration from sun exposure but they are 5 yrs old (only used during 5 months in winter) so that could be improved !!! They are pretty solid, they fell off my RV roof and only suffered a few scratches with no loss of power.

Pas installer encore mais donne le bon voltage et amperages au soleil, mais par contre le panneau solaire semble fragile!

The DOKIO 100W semi-flexible solar panel works as advertised and is lightweight and easy to install. However, my panels arrived with cracks on the front. They are functioning fine for now, but the damage is concerning and may affect long-term durability. Delivery quality could be improved. UPDATE: One of my two panels has stopped working due to water damage. There was a small crack on the corner where water got in. The company reached out to me and offered a refund. I informed them of the damage and how I believe it happened and it looks like they’re going to improve their packaging, which is good. I love to see a company who is willing to change.

C’a représente le meilleur panneau de 100 W, par rapport au prix que j’ai pu essayer dans les cinq dernières années dans les produits Amazon. Je recommande ce panneau à tous mes amis depuis quelques années, et tout le monde est très satisfait. Il est souple, et il produit une puissance qui n’est pas 100 W, mais qui s’en approche quelques fois

Bought in February and didn’t install on boat until June. Seemed to work okay but not a great output for two panels.. took it apart today and realized one panel was putting out zero charge and is defective. Amazing customer service! They contacted me after this review and after a few back and forth exchanges they offered to replace the panel that wasn’t working. It arrived super quickly and I will install on my boat in the next couple of weeks. Looking forward to having two solar panels working. Good company and service.

Been around the block a few times! and this panel is way better then expected. Now one thing to keep in mind it's really a part time solar panel I would never expect it to last permanently mounted outside. Camping and to charge a power station is where it's best suited. I consistently get 5.8 amps in direct sunlight in to my LiTime 50 amp lipo, I am not interested in watts it's the amps going in your battery that say it all. So get inline ampmeter to confirm performance and yes it's delivering more then it's rating of 5.65 amps.
