Description
- 【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.

These do not quite meet specs. I had a bad feeling when I measured the voc and they both read 1 and 2 volts low. I have them under optimum conditions, high noon perfectly aimed at sun 70 degrees home in series to a victron mppt controller that is right next to battery bank. These panels put out 100 watts each under the very best conditions. Nice looking and good form factor.

On a cloudy afternoon I was getting 90 off the front and 80 with the back facing the sun 👌😎

Seems fine
Need more sun to judge output

I’ve always heard that Renogy was one of the top names in Solar Panels, and having received this one that I recently ordered on Amazon from the Renogy store – I believe this assessment to be true. The panel looks very well made, and when I tested it today outside in partially overcast skies I measured the open circuit voltage to be just as specified. I included a picture of my meter reading, but just prior to my grabbing my cell phone to snap the shot the measured voltage was actually up OVER 21 volts…but the clouds were particularly variable.
I originally ordered the panel to use for charging a portable power station that I have, but that’s overkill – I really don’t need 115 watts for that job (20 or 30 would serve adequately). So upon thinking about it I actually may mount it rather on the roof of my garden shed, and use it to charge a small bank of 12 volt AGMM batteries that I removed from my electric lawn tractor when I converted over to Lithium batteries instead. I’ll get better use out of the panel that way – and if I need to during a power outage I can charge the portable power station by plugging it in to the battery bank instead!
The panel appears to be very well made, with an aluminum frame with pre-punched holes around the lower perimeter for flexibility in mounting methods. I really like the bifacial design which allows squeezing out more power out of the cells than a monofacial panel. Additionally, a bifacial panel is reported to run cooler, which helps to keep it in a more productive temperature range for improved efficiency. That’s particularly important here in Souther Florida, where the temperatures tend to soar.

Best PV Panels on the market! Unfortunately Renogy customer service sucks!

Wildly impressed with this panel in early testing. Pulling rated 220W by 12pm in traditional/flat mount orientation with a 60A MPPT SCC, not taking into account bifacial reflection. Will be running some more tests in a proper mounting style for this bifacial panel, but so far I’m impressed. Daily averaging about 12.5 amps output at 15.6V (195W) so far.

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 like this panel because for being 115 Watt panel it’s size is not that large & heavy compared to other 100+ watt panels. I carry it in and out every time I use it. The most I have gotten out of this panel is 108 Watts. It seems to deliver really good every time I have used it. Problem I had was that my panel came with 2 different connectors on the back, one was the standard MC4 the other was H4 and two different tools/keys are needed to disconnect them. Even Renogy support didn’t know this and it was a nightmare dealing with them, never did solve the issue with them had to figure it out myself. Tried Renogy support many times and can’t get any satisfaction.
