Description

Why is the actual output sometimes lower than 200W/400W? This is normal for regular products. Rated power is lab-tested. Actual output varies by light, weather, angle and temperature. Higher wattage panels deliver more power and faster charging. What can this solar panel power? 200W: RV batteries, mini fridges, small off-grid devices 400W: Home backup, cabins, large power storage Will it still work on cloudy days? Yes. Advanced N-Type cells help maintain stable power output even in cloudy weather, yet output still drops slightly and charging will take longer. Will it survive outdoor weather? Yes. Engineered for dependable outdoor use in rain, humidity, marine environments, RV travel, and extreme summer heat. It is highly resistant to extreme conditions, ensuring reliable performance for up to 30 years. Can I add more panels in the future? Yes. Easily connect additional panels in series or parallel to expand your power system anytime.

    • Powerful and cost effective
Color: 400W - 2pcs 200W-Bifacial 52.76''×26.38'...
These actually worked great. They give out 300w on an average day. Ive gotten all the way up to 350 messing with the angles without clouds in the sky. But I would say 300w on average. Use it with my Bluetti. And power my A/C, and hydrogardens and lights with it and my ring cameras all night and day. Overall. Impressed. Will be buying another set. Easy to mount, great price compared to other similar ones. And light weight. I actually have them on my shed. And they weigh less then my other 200w panel. ... show more

Color: 400W - 2pcs 200W-Bifacial 52.76''×26.38'...
These panels are very flimsy compared to my old csun panels. one came scuffed up on the side and the other panel bottom corner protectors broken and the ones that aren’t broken just come right off. I tried the panels for 2wks with sun, partial sun, full sun… in parallel and in series… either way the max watt they put out was 250watts combined … maybe 260w since my battery reader may take 10w… but nowhere near 400watts for both panels at the best sun and angle. I was planning to return them but was offered a partial refund and just decided to keep them only because I figured maybe panels these days are just made this cheap and the refund makes it more acceptable. Would I recommend them… or buy them again, probably not. Power output and overall quality needs much improvement. ... show more

Color: 400W - 2pcs 200W-Bifacial 52.76''×26.38'...
The ad says 200W/panel. But the data label on the panels say they only produce 10 amps max. That's 200 watts IF the full 20-25V open circuit value could be used. These panels are not 200 watts under load. Only 2 of the 4 panels purchased arrived, and the box had some tears in it. No visible damage was found, and they both produced an open circuit voltage of 22 just standing up. The other 2 in the order had "some kind of problem" and instead of making good on the order it just got canceled with a refund for those 2. So my project has been SNAFU'd! ... show more

Please test and inspect your panel before mounting it, we see to have a quality control issue. I ordered 10 and received 4 so far so I will update. So far they work but look at the photos, the bus bars are very suspect.

The panels are labeled 24volts and not 12v. That’s great for my application because I can use the panels in parallel to get the full 400w with 24v. They work great on my shed to charge the battery backup that I use to run the electric in there.
