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!

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.

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.

Great solar panels are being used, utilizing six of the 400-watt panels. The bifacial production is excellent.

Each of the 200w panels only puts out about 116 watts. If you are planning to mount them flat, I would consider another item. I am keeping them since they are already installed.

I'm lucky to get 140W total from both panels. Buy something else if you want a good panel. These aren't good.
