Maximize Your Solar Potential
With PERC technology, the Renogy solar panel can reduce recombination loss and improve the cell’s electrical properties, generating more power with less sunlight, making it ideal for use in low-light conditions.
More Energy Even in Partial Shade
The half-cut cells deliver high performance and efficiency by reducing resistive power loss, enabling the panel to generate more power with less sunlight.
Withstand Harsh Weather Conditions
10 busbar design allows for a more efficient collection of energy, resulting in higher power output and faster charging times. It also improves the durability of the panels, making them more resistant to damage from hot climates.
Build to Last
Every component of the Renogy bifacial solar panel is engineered for maximum efficiency, durability, and longevity. Its rugged construction makes it an ideal choice for outdoor use. By vertically arranging the panels, they capture more solar energy during two peak periods of the day, increasing their overall efficiency.
Capture the Power All Day Long
Vertical arrangement of bifacial panels enables them to capture solar energy during two peak periods of the day, which are sunrise and sunset,thereby increasing their overall efficiency.
【Bifacial Energy Yield up to 30%】 With the ability to capture sunlight from both sides, this 115 watt bifacial solar panel can provide up to 30% more energy compared to traditional solar panels.
【More energy even in partially shaded】 With its innovative design that incorporates PERC, half-cut cell, bypass diodes, and 10 busbar technologies, this 115w Bifacial Solar Panel can maximize energy output even when partially shaded and protect the solar cells from overheating.
【More Generation on a Snowy Day】 The bifacial design of our solar panel helps to accelerate snow shedding and warm up the panel more quickly. Additionally, with the back side always available, our bifacial solar panel can continue to provide unstoppable solar power for your off-grid life.
【Fast and Easy Installation】 20 pre-drilled holes on the back of the panel allow for fast mounting and securing, ideal for off-grid applications including RVs, rooftops, cabins, yachts, sunrooms and more. To get the most out of your solar panels, they are recommended for use with Renogy’s RV Tilt Mount Brackets, Z-mounts, and corner mounts.
【Build to last】 With a durable IP68 rating junction box, and the ability to withstand wind loads of up to 2400Pa and snow loads of up to 5400Pa, plus an enhanced 10-Year Workmanship Warranty and over 80% Output at 25 Years, our bifacial solar panel is a reliable and long-lasting investment for your energy needs.

Very Good Production From the 115W Bifacial Panel
This solar panel delivers when it is positioned with proper angles. I have seen this 115W panel reach 125W because of the nature of the bifacial panel. I would definitely purchase it again and it is the third set of Renogy solar panels I have purchased. I have this one, a 220W suitcase portable panel and two older 100W panels installed on my RV. With all 3 panels, I get good solar production but they are all rigid panels with some air movement under them to avoid being heat-soaked.I frequently read of others not getting good production out of different brand solar panels. The Renogy panels I use, I don’t seem to have that issue.

Renogy 220 BiFacial Panel MC4 male connector issues
The Renogy 220 watt panel production is fine. I could not get the male panel mc4 connector to snap into my Windy Nation Extension cables. The panels mc4 connectors snap into panel to panel just fine. The mc4 connectors snap into Renogy extension cables just fine but I could not get them to snap into other brand mc4 extension cables. Using other brand extensions they would pull apart. Be sure and buy Renogy extension cables if needed as not to have mc4?connection issues. In my opinion mc4 connectors should be standard mc4. Connecting the panels end to end long wise the cables were just a few inches short and I had to use a short extension mc4 cable between them.

Great panel
Renogy always makes quality equipment. Not sure they are worth the extra cost but only time will tell. I do have a couple of bargain panels that put out the same power side by side. I just needed one more to boost my string voltage.

Decent Panel
Decent panel, but don’t expect any miracles with the performance. I bought 2 of these and run them in series to charge an EcoFlow Delta 2. The max performance on a clear Colorado winter day was 190w per panel… So 86% of the rated amount. Really not bad at all, but in similar conditions I have seen the EcoFlow 220w bifacial panels make more than their rated amount. Certainly not a scientific comparison…just noticed better output from the EcoFlow. I like these Renogy panels better than the folding EcoFlow version because I want something I can leave outside without worrying about the high altitude UV destroying them.The biggest issue is the connection cables. The other reviewer that said the MC4 connector has a problem is right. The connector is built for a permanent install and you can’t get to the little retaining clips to release them unless you use 2 small screwdrivers. You could cut the extra plastic “bridge” piece out so it will function like a normal MC4 or even crimp on a regular MC4 if you will be connecting and disconnecting them regularly. I don’t know why they would do that. Not a deal breaker, but something to be aware of.Also with the cables in the middle of the panel they did not make the cables long enough to connect in in series when mounted in landscape orientation so if you plan on doing that you will need an extension. If they would have just made them 6″ longer it would work with a bit of wiggle room. They work great if you are mounting them in portrait orientation.I will likely buy 2 more of these to complete my system despite the issues I mentioned here if they go on sale again.I will update the review once I can do more performance testing. Seems good enough for now.

I love it..!
My local RV repair owner advised me to step-up the size of my solar panel used to keep a charge on my motorhomeâs 4 12v parallel wired house batteries. After removing the much smaller and much lower output solar panelI originally installed on the lid of one of the AC units, I installed the 100 watt Renogy panel you see in the photos. The panel did not come with mounting brackets (probably my error in ordering) so I purchased them separately through Amazon. I will not drill a hole in any roof, so utilizing the 3 existing mounting points that hold the AC cover on the coachâs roof, I used tubular aluminum bar material readily available at the big box stores, a single exterior L bracket and stainless steel socket head cap screws with stainless washers and locknuts to mount the panel to the aluminum bars. Although it hovers over half of the AC exhaust fan, as you can tell by the last photo there is approximately 3â air gap between the top of the fan housing and the bottom of the solar panel. This will allow the full exit of the fan driven warm air. I couldnât be happier with the esthetics of how it turned out and Iâll be monitoring the performance of the solar panel in the weeks ahead.

Love the double sided
These panels will be more efficient. Connected them with hinges on one side and a handle on the other, added a prop so I could stand them up on one side, they work great.
