Product Description
Friendly Reminder:
For parallel or series use, please connect only panels of the same brand and model. Mixing different types may cause voltage/current mismatch and reduce system performance.
Note: 200W is based on STC (1000W/m², 25°C, 1.5AM). In real use, angle, temperature, shading, wiring, and device efficiency affect output. So actual power below 200W is normal.
Tip: For best results, face the panel toward the sun—usually south in the U.S.—with a tilt angle near your local latitude. Seasonal angle adjustment can boost output.
Note: Solar meters offer more accurate panel readings. Power stations are handy but may show lower output due to efficiency loss, cable length, or battery level.

Why is the actual power output lower than 200W?
The rated 200W is based on Standard Test Conditions (STC): 1000W/m² irradiance, 25°C, and 1.5 air mass. In real use, panel angle, temperature, shading, wiring loss, and device efficiency affect output. So, actual power below 200W is normal.
Can I connect multiple panels together?
Yes, you can connect multiple panels in series or parallel.
Important:For best results, use panels of the same brand, model, and specs. Mixing different types may cause voltage/current mismatch and reduce efficiency.
What if I receive a scratched or defective panel?
If you receive a scratched or defective panel, please take photos immediately and contact our support team. We will assist you with the next steps promptly.
Can this panel be used with different solar generators or battery systems?
Yes, the 200W N-type 16BB bifacial solar panel is compatible with most popular solar generators and battery systems. It comes equipped with standard solar extension connectors, making it easy to integrate with a wide range of solar power setups.
What is the meaning of 12V in the product title，Why is this value different from the voltage of the solar panel？
When you open the product page, you will see a title like “xxx Watt 12 Volt Solar Panel”. The “12V” here does not refer to the voltage of this solar panel (VOC or VMP), but to the fact that one xxxW solar panel is suitable for 12V system.

Happy with these.
Currently have 2 in series. Going to 3s2p eventually. I seriously doubted claims of 400 watts (especially by reviewers who submitted in early January). The sun isn’t strong enough in Alabama (at least) during the winter to get that. I installed these initially in late December and was maxing out around 230 watts in full sun at proper angle. After the winter solstice things have gotten muuuch better. I’m getting around 340 now. I expect it to continue to rise as the sun “gets stronger.” I replaced a single Dokio 400 watt panel with these 2 – 200 watters. I prefer these as they are lighter and smaller and easier to move around than a 400 watt panel. They are sturdy and I don’t worry about the frame bending or breaking. i have zero issues with these and will purchase 4 more. I can get about 1.7 Kwh in a day right now. I’m hopeful I can get that REALLY close to 2 (per pair). That would be ideal for my 4 – 200 ah battreez.My only qualm is that the cables are a bit short but thats splitting hairs.Update. I Implemented my other 400 watt panel in a different power system. it’s orientated in the same direction with the same angle but it vastly underperforms these. Granted, the others aren’t bifacial and are 12bb vs 16 but I didn’t expect such a big difference. The top Victron connect is the one hooked to the Dokio. the other is the 2 – 200 watt panels. and that must have been during some shadows as it hit 356 that same day. and it has hit 393.update – I finally got around to going 2s2p at least. I pulled 811 watts on those four panels. in April. So I’m beyond happy with that.my 400w dokio panel has yet to break 230.update – pulled 986 on 800 watts worth of panels. bifacial is for real. you can expect a 25% boost in optimal conditions. on these at least. want 1 more pair and I should be able to run my mini split pretty much fulltime. great panels. can’t recommend enough.

The POWA!!!!!! IS OVER 9000!!!!
THIS THING HAS THE POWA!!!!! lol no seriously tho it brings in more than the 2 100w panes i had if i didnt need MORE POWA!!!!!! Id sell the other panels and use just this one its crazy how much POWA!!!!! It gives you its seriously under rated so buy it while its still on sale, quality is great POWA!!!!! Output is amazing and price is decent the size is a bit bigger than my 100w panels but not by much easily fit where my old one was after adjusting the mounts, my only gripe is the cord length sucks ass i actually had to dig up old solar wire to add length until i get another spool of it to make it clean and all one wire each. Dont be a dummy buy this and save some money and make more POWA!!!!!!

You pay for 800 Watts, you can actually get 800 Watts.
I purchased 2 of these 2 packs, for a total of 800Watts. Now, usually, when you have 800 Watts of solar, during peak operation you will get maybe 720 Watts if you’re lucky. My installation on top of my RV regularly give me 800 Watts or even a bit more on peak sun hours. Very happy with the performance.

Good panel, but lower than expected output
These panel were packaged extremely well. Thick foam on on the corners and sides, as well as separating the panels. In addition to that, each panel had thinner foam on the back side the panel. The only way these would get damaged is abuse by the shipper and it would take quite a bit.These panels look so good. Good quality and assembly. Zero flaws on my set. Not sure why people complain about the cable length. It’s more than enough to put them in series and even have them spaced 12in apart if you wanted to. You are going to be running a cable to them anyhow.As for performance and why I gave them 4 stars. The voltage is spot on. I am getting 54.4 during peak sun. But, I am only getting 7.1A with a 3ft 10AWG XT60i pigtail (center pin grounded) and 7A with a 40ft extension. Well below the rating of the panel. We have had clear skies and perfect sun and that’s the best I can get. Still happy with ~380W, but after seeing some other reviews, I expected closer to 400. It is real feel temp of 92 today here in Texas 4/13/25, so maybe these panel just don’t love the heat.I’ll update my rating after trying a different pigtail and giving it a couple more months to see if production increases.

Simply Outstanding Panel For The Price and Output
I was excited to test the panel so I didn’t do a complete test…I live at 39 degrees latitude in N. Calif…The today was almost 50 degrees and very bright sun…Basically perfect solar conditions for Feb…Using my UNI-T UT673PV solar tester I got 224.8 Watts…I moved the top of the panel back and forth about a foot and the wattage only changed a watt or so…This in incredible so the panel won’t need to be re-positioned too much, if at all…I also had the panel sitting on an aluminum colored tarp to help the back input…When I get the panels installed I will check the wattage when charging and when charging/powering a power station..The panel looks well built so I see no reason the longevity shouldn’t be excellent..I will be buying a few more to get the wattage up to my needs…I believe if you try one you’ll be quite impressed…

Excellent customer service and panels.
I purchased the two pack of the black panels. One arrived with the glass shattered. There was no padding between the panels.Update to my review. I am changing my review to 5 stars because of excellent customer service and great replacement panels. The seller reached out to me and offered to solve my problem of damaged panels They said all panels will be packaged with more protective padding going forward. The seller quickly sent replacement panels. They were packed very well with plenty of protective foam. All 3 panels are working well and were producing well over 180 watts with thin clouds and not directly aimed at the sun. These are the best 200 watt panels I have found.

Not 200 watt more like 25 -50 watts
Quite dissapointed in the output it is stated as 200watt i have only been getting about a quarter of the rated watts in full sun. I will be returning and buying something else that works better
Kindle Customer –
Plug and play ready. Very efficient.
Very efficient. I am so pleased with these panels. I bought them to charge my 3500 watt power station. They are plug and play. At one point I was bringing in 418 watts. Very impressive.
