Description
- 【Ideal Output】 The bifacial solar panels adopts a transparent back 12BB solar cell design, and the back is made of composite materials, with a high light transmittance of 91.5% and a conversion rate of 23%. Under ideal conditions, the daily power generation is 1716Wh, which is a 33% increase in energy compared to traditional solar panels.
- 【Solid Components】The back panel, made of composite material, is windproof and snow-resistant. The metal aluminum frame is rust-proof and anti-corrosion. And the pre-installed hole design makes it easy to install.
- 【Transparent Back Panel】Almost 91.5% transimittance makes the back panel well convert sun scattered light even when the front side is shaded, which is widely chosen to be used in sunroom, entrance canopy, farm greenhouse and motorhome.
- 【Easy Installation】Size: 52.6 x 26.4 x 1.4inches（1335*670*35mm）, weight 20.48 Lbs. Diodes are pre-installed in junction box, with a pair of pre-attached 2.95ft Cable. Pre-drilled holes on the back of the panel allow for fast mounting and securing. Pre-drilled holes included for grounding. Ideal with large rail mounts for extra support and security.
- 【Robust Quality】Corrosion-resistant aluminum frame withstand strong winds of 2400Pa and Snowload of 5400Pa. Both the IP68 junction box and IP67 solar cable connectors has an excellent waterproof function. Allows you to use it outdoors with confidence.

Great solar panels, good performance. Only issue I have is the packaging for shipping needs to be better. So far I’ve been lucky and only had one damaged panel (out of 6) but the boxes always look beat up on delivery and I’m nervous every time I go to open one.

Power generation is very good once installed I had to come up with an installation plan once I tried with just a ladder. Plan worked and installation completed with connection to controller and battery.

It is important to me that when making an Investment like this, every panel has a serial number and temperature coefficients either in a manual or on the panel. This has both.
These panels perform very well when all factors are taken into account. Those factors are how much w/m you are receiving, air temp, humidity and atmospheric interference that blocks the sunlight that gets to the panel. All weather center and almost all irradiation meters use the full light spectrum light brightness meter and calculate watts/meter.
I bought 4 of these panels, data logged their performance them over the past 2 days and based on my data, they are indeed 195 watt panels.
With 850 w/m reading, 50% humidity and 41c cell temp, I’m seeing between 150 to 155 watts.
Considering the cells are rated at -0.5% per c over 25c and max watts at 25c is 165 watts in 850 w/m sunlight, 150-155 watts is well within specifications. This is while sitting on a rack at 15%, facing south in Florida.
The only negative I see is they are only warrantied for 2 years vs 10 from others but at this price point, you can’t beat this if you can put them in a location to take advantage of the bi-facial feature.
Overall, I am very happy with these panels.

Read 170 W at peak, paid $.65/watt cost.

Purchased to mount on a cargo trailer and I decided to test out the efficiency before installing. In full sun, properly aimed, it struggled to produce 130 watts a panel. This was disappointing but not enough for me to put it back into the box and return it. The panels seem well built and I would expect them to last for some time. Unfortunately, I don’t think they will do the job I hoped so they will probably be regulated to providing power to a shed.

Not bad for South Florida i’m getting for two panel 285 Watt With temperature 96° from 11 AM to 3 PM

Very well-made for the money, but I’m still experimenting with the benefits of a bi-facial solar panel.

Purchased these to set up a 2nd array to power my solar generators. I am still waiting to mount on my roof while I await some parts for the setup but have them on a rack on the ground currently until I complete the install. Even while not in an optimal location, they are doing a solid job generating power for my generator and inch for inch generate more power then the panels I have had installed on the roof for 4 years. Very impressed. Worth noting, you want them on a rack vs. flush on a roof because they generate power from both sides of the panel and will gain some power from surface reflection.
