Portable Solar Panel Foldable 100W 18V PV Module 9BB Bifacial Monocrystalline Solar Cell for Portable Power Station Solar Generator Camping Emergencies Outdoor Garden

Getting mid 80s watt on sunny day Put aReflective material behind and it jumped to 93 watts. Great value bought 2

As described. Well made. Generated 75W straight away in the morning sun—impressive. It’s very light compared to the glass folding panel it’s replacing, which I found heavy and cumbersome. While it needs to be handled with care, it feels durable. I’ll peg it down in the wind if needed. Overall, very happy.

Able to direct this panel directly at sunlight compare to rooftops

The media could not be loaded. Not an engineer, I am just a typical consumer.This is the first bifacial solar panel I have used or tried. I was very interested in how it performed especially since its very light weight. But the weather here has not been cooperating. Normally it is very easy to test solar panels here, but now difficult because of the never ending storms. I setup the Topunive 100 watt solar panel, and then I placed a SunPower 100 watt panel right on top of it. This gives me the exact same sun angles for the two panels. This is not a maximum wattage test, just a comparison test between solar panels. I got about 104 watts for the SunPower cells, and 94 watts for the Topunive panel, which is pretty good. I would have liked to use a mirror or some other reflective material to shine light onto the back of the panel for added power, but I do not own a mirror and the reflective material (I used Styrofoam) was hard to keep in place with the constant wind. Hopefully in the future when our weather returns to normal, I can test out the bifacial cells better.Item came well packaged with no damage. The solar panel seems well made and is surprisingly light weight. With the easy magnetic closure, light weight, 2-panel system, and simple legs that just fold out (no crazy Velcro), this panel can be set up in seconds being the fasted setup I have ever found. The solar panel has no storage pouch but it is not necessary since this closes like a clam shell, the cord and connectors are safely stored inside.Specs:• Open Circuit Voltage (Voc) 21.8 V• Vmp 18.6 V• Weight 5 lbs.• 9BB & A Grade solar panel• Monocrystalline silicon solar cell• Bifacial cells (efficiency is increased by 10% to 20%)• Metal handle• Closes with magnets• 6’ 3” cord• 20.5” x 21” x 1.5” folded• 20.5” x 42” opened• Comes with DC5521 (5mm), Anderson, DC7909 (8mm) and MC4 connectors• It states it is IP68 waterproofPros:• Bifacial Solar Panel• ETFE coated for durability• Super light weight• Very easy 2 panel setup/teardown with metal legs• Up to 23% efficiency• Easy open and close with magnets• Comes with cloth case• Comes with typically used connectors plus MC4• IP68 waterproof• Good wattage output for the price (but still less than the top rated panel)Cons:• The only con I can think of is the light weight (which yes, is a pro too). The light weight means it can be blown over easily in the wind.I will keep this review up to date if any new issues arise. At this price and with all the features, this is an easy 5 star product.

The media could not be loaded. Getting close to this being around 20 or so solar panel reviews. This is one of the better ones I have tested. I have been using it pretty frequently for a month or now. Most of the time on my Delta Mini as it has been what I test most panels on.Pros:Consistently around 85 watts when used in good sun.Handles shading better than some othersLight-weightCons:Bi-facial only might give 5 extra watts in testingStand is a bit flimsy feelingMagnet on the corners to help close it are a bit on the weak sideThis panel feel more like a flexible style panel instead of the normal glass style, they just put the flexible panel in a case form or it feels that way. This makes for a very light-weight package. I like the variety of connections all on one plug. I feel most give adapter cables that you then have to connect. This you always have them ready to use. I do wish an XT60 was on this too, but they covered the rest well.The stand feels a bit light-weight and I am little worried if something will get bent, but so far so good. The magnets at the corners to help keep this close are a bit weak and after folding up the cord, it seems to be too thick and never wants to stay shut easily. Back in the case it would ok though. The size of this is good and a bit more compact than some of my other folding 100 watt panels.To try the bi-facial part, I pushed this up against a surface to limit the ability to bounce light and it was around 80 watts. I then set it up with the stand on a concrete sidewalk and got 85 watts. I have heard of glass bi-facial exceeding their rated output, but not the case here. It does seem to help some and might be way it does a bitter better with shading.Overall, I like this panel and it performs well compare to other folding panels. The price when review was a pretty good deal too, but that can vary. A good coupon or sale could make this a great deal. This is certainly worth a look in your solar panel shopping.

I recently purchased the Topunive Solar Panel Foldable 100W, and I must admit, my experience has been less than satisfactory. While the panel's lightweight design initially seemed like an advantage, it has proven to be a significant drawback. Even the mildest gust of wind has the potential to flip it over or send it flying, causing unnecessary frustration and concern during outdoor use.Furthermore, its performance has been underwhelming, with the panel yielding only about half of its rated wattage output even on the brightest of sunny days. This significant disparity between the promised and actual power generation has left me questioning the panel's overall efficiency and reliability.Additionally, the issue with the cords being permanently connected has proven to be a mild inconvenience, as it restricts the ability to add other cables and causes tangling when attempting to fold the panels into briefcase mode. This lack of flexibility has further added to my disappointment with this product.Regrettably, I cannot recommend the Topunive Solar Panel Foldable 100W to others, as its unreliability and impractical design have overshadowed any potential benefits it may have offered.
