Description
- 【Bifacial Energy Yield up to 30%】 With the ability to capture sunlight from both sides, this 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 220 Watt 12 Volt 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 bifacial solar 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 bifacial solar panels, they are recommended for use with Renogy’s Tilt Mount Brackets, ground mounts, Z-mounts, corner mounts, or pole 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.

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.

I hooked this solar panel up to my 40 amp MPPT charge controller in my camper. I tried the panel facing the sun and then turned the panel around with the back facing the sun . The solar panel is amazing it works on both sides . And the solar panel worked very well . The line voltage started at 22v and dropped to 16.3 volts and 18.5 volts the charge stayed consistent at 6.5 amps . The ability for both sides to charge is very cool. I am definitely impressed with this solar panels performance.

The media could not be loaded.
Panel came in a very well protected box. The cardboard box even had a handle to carry it like a big briefcase.
The connectors are standard MC-4 connectors, the standard that all permanent solar installs use. However, you can certainly buy/use a MC-4 to (USB-C, Barrel DC port, or other connection) that your device/battery uses. I normally don’t like to mention other reviewers, but the information stated in the previous review is not correct. The cable that you use (if not rooftop mounting), would be dependent on your situation and can be purchased very cheap.
On those same notes, it never stated that the mounting system was included. It also shows a picture of an RV but that is not included! Please make sure to read the details of the ad before purchase.
I did some testing of the panel, prior to mounting on the roof (which I have not done yet). I used a portable battery, which is not as efficient as a full stationary system. I also did this at 8:30 AM, so the sun was not full and I was pointing East/West, where the sun is South for me. With this all in consideration, I had fantastic results:
1. First, look at the picture of the panel on top of the old panels I am replacing. The old ones are slightly larger, but they are 100 watt. These are 220 watt! So over double the power for a smaller footprint.
2. Tested with the panel facing down toward the concrete vs up to the sun (slight angle down) – 98 watts.
3. Tested east facing full sun – 185 watts! This is great, considering 8:30 am, non optimal placement, and inefficient battery charger. Once hooked up to my permanent system with optimal placement, I can certainly see this hitting higher than 220 watts.
4. The best part – see the video of me testing with the panel half covered. With my other panels, any shade will quickly drop my output to 10 ish watts. These stayed strong at 90 ish watts with half the cells covered.
Overall very happy with the panel. I am considering making a carport with these for the roof. They look really nice, and have a cool effect from behind when the sun is hitting them.
The aluminum frame is built well, and can see these lasting many years (assuming mounted correctly). These panels would be a great option for RV use, areas that will have occasional/partial shade, or for someone who does not have much roof real estate (or can’t handle a heavy weight load).
Highly recommend!

I’m not going to knock anything off for the odd shape, because it’s actually exactly what I needed and is smaller than my other 100w panels. I get full output in good sun and it puts out more power for longer. This is my first ever bifacial and I am so impressed I am considering switching out all my panels and relegating the old ones to some other purpose like my workshop or something.
How My Star Rating System Works & What They Mean:
1 STAR – Pretty much junk and I would return and ask for a refund if I could.
2 STAR – It works, but barely meets the minimum requirements it should in order to keep it and not return it, but I would not order again.
3 STAR – It does what it was designed to do, but there’s nothing really special about it. It’s acceptable but not great.
4 STAR – I am very comfortable recommending it to a friend because it is is well made, durable, and delivers on its advertised features, and I would buy it again.
5 STAR – I really love it. The item exceeds my expectations of quality, durability and functionality. Not only would I purchase it again, but I would also actively encourage friends and family to to do the same.
All of my reviews are my own personal opinion and are completely honest no matter if I receive an item for free or I pay for it. I am an avid Amazon shopper, as well as an Amazon Vine Voice and I personally rely on reading reviews to make all of my buying decisions, so I understand the importance of honest reviews from my peers.

Ordered two of these and the m4 connectors on one were not finished and had solid strip of plastic making it impossible to use the clips that make the m4 adapter functional.
