DOKIO 200W (2×100W) Flexible Solar Panels 18V Monocrystalline for 12V Battery Charging, Semi-Flexible ETFE with MC4, Series/Parallel for RV Boat Camper Van Trailer Off-Grid Use

For the price I think these are great, I got a bad panel, but was replaced by manufacturer in the first 30 days. On a bright day I tested each of my panels making about 80-95w per panel. My use is very niche running a computer in my car, but it runs everything very well with a sealed gel battery and a simple battery maintainer

Output is good. It's flexible enough, but won't last for years. It's kind of a entry panel to get into the solar power. So don't expect a lot from it, but it will do what it's rated to do. It's not pretty, it's not that durable, but it does the job and it'll last till you inevitably upgrade

Very poor quality compared to other brands I have . The back feels like paper . The solar production after a couple of months of use dropped to 20%. I will have to replace them. Then peeling off after a couple more months. Now is only paper support. Terrible quality product

My two 100 watt panels were shipped quickly and securely packaged. The panels are lightweight and easy to mount, but not particularly robust. They are easy to scratch even when handled with much care. They are prone to damage from eve light winds if not completely secured. Neither of my 100 watt panels has been able to yield more than 39 watts, even when mounted next to another 100 watt panel that was yielding 70+ watts in the same conditions. I like these flexible units for charging my RV batteries without having to leave my more expensive and productive panels out when I am not around, but I do wish these units were more efficient.

These panels are lighter in weight than rigid ones. More documentation or description would have been nice. They have MC4 connectors, which would have been nice to know for planning purposes. I easily got 75 watts out of each panel on a partly cloudy day.

Working well, easy to install, lightweight.

I bought 4 of these 100w panels, for a small camping rig. I have been playing with solar for at least 15 years so know what to expect. Simply put these underperform, the absolute maximum power I can get out of them in perfect conditions in peak sun is 275w for all four, doesn't matter if they are in series or parallel and I have tested them on various mppt setups, on average they put out around 250watts, which is rather disappointing. From what I can tell these are not really flexible, they seem like conventional cells on a flexible backing. Probably fine if you plan to mount them to a slightly curved surface but they won't last if you store them then bring them out when needed. Do they make power yes, do the meet the claimed specs no, are they cheap yes. Should I return them probably as the price per watt isn't that great when calculated with the actual output.

After having an issue with a complete system that I bought from Dokio, they showed great customer service and I decided to buy these panels. They increased my voltage by more than double. Very light weight and easy to install.

Packaging was great. They are very light which is great. The quality looks good until you pick them up. It was my first time buying flexible panels and the first time I picked them up it felt like the panels were cracking between my fingers. I don't know if this is normal but it makes me afraid to move them as I don't want to damage them. As for performance. Was a full sunny day with low haze. I was getting roughly 55 watts per panel. I had them in series and they were providing 110 watts total. A bit disappointing. I had them flat on the ground so hopefully they will perform better at an angle. I'll try to post an update after I get some camping time in. Update: so the same evening I received the panels, after a day in the sun, I noticed that both had scorch marks. The next day I couldn't get hardly any power out of them. I'll be returning these.

These work ok but it would be nice if the cables came with the unit.

Au Québec, l’été, soleil radieux, les panneaux fonctionnement à 21%, 5 hre/jours x 60w x 2, au lieu de 100W x 2

2 panels. one produces half the voltage oh the other one, in the same conditions and same time.

I have used Dokio brand few times now, never had a problem, I have six 100 watt panel on my RV trailer roof. My oldest Dokio panel is 7 years old. My voltmeter tells me all is still good with old panels, I recommend Dokio panels as to price and quality.
