## Description

desertcart.com : Topunive Bifacial 100W 12V Solar Panel 9BB Monocrystalline Cell 12 Volt for Marine RV Trailer Boat Cabin Van Car Uneven Surfaces 12V Battery Charge : Patio, Lawn & Garden

Review: Still a great after 1 year of use - Its been 1 year and so far so good. I have 4 panels in a Series+Parallel config and I regularly get 300w, in rare cases have seen 330w, so 75-82w per panel. Can't complain about that! I also have 2 Renogy panels which perform at the same % of power under the same conditions. I worry about the longevity of these, as it appears that some cell clusters are darker/lighter when you view them at an angle (see picture). Maybe that's normal, or maybe there is some UV fading, only time will tell. But no drop in output yet. I like that these are low amp (6.6 Isc) so I can run them in parallel and stay under my 15A limit. Low Voc (18.6) means I can technically run 3 in series and stay under the 60V limit of my power station. I've tried running 3 in series (in hot weather, so not calculating for low-temp voltage) and they work but sometimes I've gotten nothing when I connect the wires, so I don't know if there was a bad connection or maybe the stated Voc is slightly higher and maxing out my unit. I need to figure that out as I might get 2 more panels and run a 3+3 S&P config. The weight and size to wattage ratio of these is excellent. I got them to go on my van conversion, but when I'm not traveling I take them off and put them on a homemade rack to offset my home electricity. This light weight setup means I can easily move them around the yard by hand to keep them pointed directly at the sun throughout the day. Good purchase and would buy again.
Review: Good product - It’s a good flexible panel with its price.

## Features

- Bifacial Solar Panel: (it is old version, product size is:41.3"L x 22.2"W x 0.2"H, the size is different from 2x100W new version). Compared with traditional solar panel, this bifacial solar panel can generate electricity not only from the front side, but also from the back side, efficiency increased by at least 10%-20%. (Package does not come with the kickstands that the photos show).
- Lightweight & Easy to Install: It is only 0.2 inches in height and weighs only 4.4LB (2KG), the solar panel is easy to transport, install, hang and remove. The pre-drilled holes and PV solar connectors help you install easily and quickly.
- 9 Busbars Solar Cell, High Conversion Efficiency: 9BB & A Grade Monocrystalline silicon solar cell provides high conversion efficiency up to 23%. The narrower busbar space and more cells receiving surface bring lower cost and increase the output of the PV module. Compared with 5BB panel, the 9BB solar panel ensures lower risks of microcracks and longer service life.
- Waterproof & Dustproof: This solar panel is equipped with IP67-rated junction box to effectively block water splashes and dust from outside, making it perfect to be used outdoors. It is much more durable than traditional glass and aluminum model solar panels. 2 pieces bypass-diodes are built in the junction box.
- Excellent Quality: The solar panel is made of ETFE material, which has a higher light transmission and longer service life than ordinary materials. The back panel is made of TPT, which is good for heat dissipation, waterproof, high temperature resistant and easy to clean.

### ⭐⭐⭐⭐⭐ Good product
*by B***N on December 27, 2025*

It’s a good flexible panel with its price.

### ⭐⭐⭐⭐ Works up to specs, but when not on sale it cost almost the same as 2 100w panels.
*by A***H on June 18, 2024*

Some of these panels sometimes arrive bent on the outer aluminum frame, I know these bend a little, but shipping damage can break or crack the solar cells near the aluminum edge. This company needs to package them better, often they get bent or damaged in transit. Only gripe. It works well up to specs rating. But i do not know if a bi-facial panel works any better as just the one sided panel ??? The price is good on sale....I think it puts out 120 watts in bificial sun? Not sure yet have to do a solar array test. I have these wired in pairs series, to make 24v. Make sure buy in pairs, 2 solar panels to make 24v. Less large wiring, more efficient in 24v over 12v. No reason to not get a 24v mppt charge control, even when you run 12,v batteries, you always run 24v solar to a mppt charge controller, it auto detects the proper charge voltage either 12v or 24v batteries, using 24v solar always, much cheaper to wire. No need to ever go 12v solar if you can avoid it. And or buy a 24v panel single, either way they make 24v. Good for efficiency. I do like the tiny bubble magnifiers built into one side of this panel. Seems to collect light rays at almost any angle. Not angle sensitive so that is a plus. Would work great on a flat roof like house or RV roof. Plus it weighs a lot less than an aluminum glass framed panel. Plus it's flexible to match contour of a RV roof up to a point, don't flex it too much. The other side bificial I will test output soon. I'll get back...... However needs spacers underneath to catch light on bottom of panel and for cooling panel. Plus one side of panel uses different colored solar light gathering diodes cells. Not sure how well bi-facial panels work ?!? Seems to be inconsistent different colored diode cells on one side. Probably okay. Works better on face side, more voltage and amp output. So who knows without testing. Front face is all the same quality. Has nice aluminum thin frame around perimeter. Nice looking and light weight. Looks durable enough. Has a good warranty. Time will tell.
