These bifacial panels are very impressive, I have been getting 380+ watts per panel (90% of rated wattage) mounted on my mobile mount. With the mount I can perfectly align the panels with the sun throughout the day maximizing the energy output. Even on very cloudy days these panels can provide 100+ watts, amazing. Compared to portable panels I own these at 1000% better for solar output. Being bifacial panels allows them to harvest even more power by collecting solar radiation that bounces off the ground on the backside. This is a great investment to easily power your solar generator. I have 2 sets of panels in parallel which generator 1200 - 1500 Watts of energy and they can produce anywhere from 6000 - 10000 Watt Hours of energy per day which covers most of my baseline power use for the house per day.

My off grid cabin has been operating my fridge 24/7 and these panels are keeping the batteries topped up. Working well.

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 currently have four of these panels and am very impressed with the output. They are nicely constructed and look very nice with the black frame instead of silver. I look forward to adding more panels to my ground mount array soon.

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.

Only issue was the packaging it came in as of today with rain and clouds it produced 75-225watts at 4 pm and it’s a 400 w bifacial panel so I think it’s done well will update in 6 months

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.

In northern SC, winter time, very little direct sunlight. With one panel up for testing, it average 200 watts with very little sun. Even when sun was barely touching the panel, it was still getting 80 watts. No sun, just overcast, 30 watts. Update, winter time, direct sun, pulled in 779 watts, consistently for around 30 minutes. Will update when more sun is available and reflective back side.
