Size: 1 Piece 400W Bifacial N-Type Solar Panel
Got two of these to charge a Bluetti EB240 battery. They are well made and have better output in cloudy conditions than the portable Renogy 400W "suitcase" I tried before. With the Bluetti EB240, I only got 300W charging with two of these panels in parallel. Connected serial, the Bluetti displayed an E017 error. Ended up only keeping one of these panels, which gives 275W charging with the Bluetti. The price for these panels is really good, at $236 with a coupon.

Great solar panel. I have mine mounted on the roof of my camping suv to charge my solar generator, even mounted flat (worse possible setup) it still produces up to 350 watts in full sun and on rainy overcast days it consistently reaches 60-150 watts.

The panels seem to be of good quality and in the short time I have used them the provide nearly the rated power. The problem is receiving them without damage. The first set of two panels didn’t even make it to my house, they were so destroyed the shipping company didn’t even bother to bring them. The replacement set did make it but the box was practically destroyed when it arrived. I was hesitant to accept the delivery but after inspecting them and talking to Amazon customer support I decided to try them. As I said before, the panels do work, the frames are banged up and gouged a bit but for my application I guess it’s Ok. The packaging must be improved before I would consider buying more of these otherwise nice panels.

Great value for the money！ After several months of use, these 200W solar panels are working great. Performance is solid and steady, keeping my shed powered without any hiccups. I was pleasantly surprised to see them actually hit a peak of 208W in good sun! For the price, the output and quality have been excellent. Well worth the cost—no complaints here.

I installed double-sided (bifacial) solar panel as a shade roof beside my pool and it has exceeded expectations. It’s attractive, solidly built, and does exactly what I wanted: provides comfortable, consistent shade while harvesting extra energy from both direct sunlight and reflected light off the water. Dual-sided energy capture is a great deal, the back side picks up sunlight reflected by the pool and surrounding surfaces, noticeably boosting output versus a conventional single-sided panel in this location. I roughly get at least 20% more power harvested with the same price. Optimal placement matters, I found it would be better for panels installed higher above the water and angled toward the midday sun gave the best combined direct+reflected yield. If you plan a similar setup, consider a slightly elevated mounting to maximize rear-side exposure. Anyways I will keep sharing new findings, so far I am happy with thie great product. If you want a dual-purpose solution — comfortable poolside shade and stronger solar generation, this double-sided/bifacial solar panel is an excellent choice. It’s efficient, solid, and cost effective.

Fantastic Performance ! I recently installed this 200W bifacial solar panel on my backyard shed project, and I've been thoroughly impressed. and it actually delivers. The build quality is solid. The panel feels durable and well-constructed, which is essential for withstanding some unpredictable weather here. I have it mounted on a slightly raised, angled frame over a black gravel surface. On a sunny day, my monitor shows I'm consistently getting a 10-15% boost in output from the rear side capturing the reflected light. That's free extra power I wouldn't get from a standard panel!

These panels came shipped great, one of the panels Voltage goes up and down too frequently, im not sure if there is a short somewhere or what, but that is why I am giving a 3 star rating, the other panel works fine, but I have 3 130 watt eco worthy panels that produce more steady power than these panels produce because of the one bad panel, or voltage drop issue.

This 200W bifacial panel has solid build but lack sufficient quality control. Example: sealing material exposed and missing cap for junction box.
