Renogy 120W Solar Panel

This works great! We covered a couple squares with our hands. Each square brought the charging down about 10 watts. I'm very happy with this kind of panel. Value compared to my portable panels, I think this will last longer in this Arizona Sun! Always brings in more than 160 watts in full sun. It's not considered portable but it's not very heavy.

These are very good solar panels for RVs. An RV roof is busy with vents, AC units, and shade trees that cast shade on panels. The ShadowFlux has diode bypassing so if a leaf or partial shade from an AC unit hits you won't lose total production. These are the perfect size for Travel Trailers. I buy, sell and install these for friends and family. I've installed these on RVs, job site trailers and Race team hauler trailers. I always make it standard procedure to test the panel before I put it on the roof, today in Southwest lower Michigan April 3rd, with a blue sky, the solar panel tilted to the sun was making 183watts, and last June I was getting 202watts with a blue sky. I can cover the panel with my hat and it drops down to 142watts which is to be expected, the standard type N would drop to 70 watts... THE diode bypassing technology is a game changer and went paired with type in Construction cells, It doesn't get any better than this. Size: these are a couple of inches wider than the 200 W panels of four years ago and about 4 1/4 inches shorter. A plus! Measured size is 30"x 49 3/4" and weighs 24lbs... This translates to smaller size and more power out, they are more efficient. They can be used in series or parallel, I install these on 12 V operating system system RV's all day long and I let the charge control controller do its magic. The open circuit voltage is 36 1/2 V, when plugged into a charge controller to charge a battery a solar panel voltage is 31 V plus or minus Sunshade, and your charge controller is set up for your battery voltage, everyone deal with is a 12.8 V operating system... Don't let some of the reviews on here concern you about the voltage, your MPPT charge control controller will allow you to set the battery voltage ! These are a great value with 28 bypass diodes per solar panel, incredible advancement in solar technology. A great value for your money, especially with the smaller footprint, the power output, and the ability to charge well on days when it's not perfectly sunny. We just recently added a second one to my brothers camper and he loves it for keeping his batteries topped off, and the refrigerator is cold! Will Prowse also have these 5stars of 5! Look him up! -Keith 3dayrv.

I purchased a single 200w Shadowflux panel thinking I’d be disappointed and would probably have to return it. Nope! All the hype is true. These panels will actually put out a bit more than their rating. They also excel at making power in mottled shade, which is a game-changer for mobile use. I was impressed enough from my initial testing to order 5 more, which I promptly installed on the roof of a 24 foot toy hauler. Rolling along between 11:00 AM and 3:30 PM I routinely see between 1000 and 1200 watts, with excursions to 1300… at which point the Victron MPPT clips it. In a 12-volt system thats >100 amps of output. Something for all my toy-hauler friends to know: two 200-watt Renogy Shadowflux panels mounted end to end span 100 inches. So if you have an 8.5 foot wode trailer (ie, 102 inches) this means you have a perfect fit. The panels are 50 x 30 inches, which means you can stuff 1.2 kw of solar in LESS THAN 8 FEET OF TRAILER LENGTH. Pretty cool, especially when you realize that a 10.000 BTU 12-volt inverter AC can be run on high (60 amps) even while you are reliably putting 20-30 amps back into the battery. And that is just for six panels. Add a few more panels and some big LiFePo4 batteries and you can have a complete no-worries off-grid solution. I’m giving these a solid 5/5. Well worth the extra cost IMHO.

This is my third setup; first a mix n match basic idea test; then a basic brand of same panels total 400w wired as 2s2p; finally after a while I found a deal on this Renogy 200w x 2 set (don't worry if you missed the deal, there's always a deal later, as I waited for almost a year) comparing 400w vs 400w side by side, the shadowFlux beats the other by a mile, about 15-20% more everyday. The shadow flux works great because: A. there are two big trees on the east and west side. and that contributes to part of the difference. B. When in noon where the sun sits in the middle with no shadows, the basic brand give about 300w while the renogy give 350w. In this case it's true that you pay for what you get. Great panels, Renogy. Go solar.

Could not be more impressed with this* It's far lighter than another folding, portable array we have that's rated for 400 watts but has never actually achieved anywhere near that possibly because we're not on the equator, a defect or a used item sold as new with a defect* Whatever, this array works splendid* This is half as heavy and though it does not fold up, it takes up more or less the same space in the car as the folding version of another brand* It's proving 158 watts out of the box in less than perfect conditions as it's somewhat hazy out and this while the array is a little bit in the shade* Whether you have a fixed or mobile application, this is the best we've had so far* Pro tip for mobile: they sell these clothes hanging rods on Amazon that clip into the grab handles of a vehicle interior* We use one on these deployed in the rear passenger area and then another suspended from 'S' hooks from mounting brackets already welded into the car body* Use the polyethylene packaging strips as a cushioned platform for the panel to ride on, tie these onto the clothes rods with rope so they don't move around* We open the hatchback and slide the panel onto this assembly face up towards the ceiling* It doesn't take up a lot of room and the panel doesn't extend into the forward cab area or take up any head room*

I bought two of these Solar Panels and they work great for what I need. I put them on top of my Express Van. I use a Renogy Rover 40 amp controller. I run them into a big Duracell AGM deep cycle battery. I run a Chinese diesel parking heater and a vent fan off them. The controller is in float mode most of the time at about 13.8 Volts. I am in North Dakota and as long as I can keep the snow of them in the winter they keep everything charged. I also have them linked to a AGM start battery under the hood that is hooked through a isolator. I have had this set up for a while and never had a problem. Both solar panels came shipped in the original manufacturers packaging and nothing was broken. Very Happy with them and would buy again.

FIRST SAVE THE SHIPPING BOXES- my mistake thinking I would not need them. You will for warranty claim to ship back! I bought 3 of these panels for top of RV. From the start I questioned if working correctly. Sometimes it looked like working right but then next day or 2 they would hardly put out 100 watts out of 600 in full sunny day. It’s been over 5 months now and have never seen over 400 watts total from 600watts in full direct sun. Been going back and forth with manufacturer-Renogy for over a month now. They are very slow to respond you and keep requesting taking different multi meter measurements instead of all at same time. Finally agreed to replace the panels but will have to send them in first before replacements sent, so if you didn’t save the shipping box you are SOL…so this is where I’m at now. I offered to provide my credit card number to hold so they can send out the replacement and I can use that box to return them. Well at first they said yes now they are saying no claiming per their policy…? Their policy is a “suitable box” what the heck is a suitable box and where would I get a large 200watt solar panel shipping box? SO KEEP YOUR SHIPPING BOXES ATLEAST UNTIL WARRANTY RUNS OUT! The only PRO and 1 star treatment is they do provide a return shipping label, that deserves a star. definitely be cautious buying these panels, I was sold on the anti shading technology but if it doesn’t work right it doesn’t matter what technology it has and the manufacturer’s service is definitely lacking and be ready for a long drawn out process. I believe it’s overseas customer support too the email responses come later in evenings and the middle of night, during early in the week is slow to no response. Sometimes 3-5 days before a response.

I have an off-grid Reolink TrackMix camera running off a Victron 100/20 MPPT, a 50Ah LiFePO4 battery, and an older technology 100W panel that output about 65W and 4.2Ah peak on a good day in Southern California. Even though the camera only pulls about 0.4Ah on average, I was experiencing situations where the battery would not reach absorption, or even run out of power after a couple of cloudy days. I decided to experiment with the Renogy ShadowFlux 120W panel, because it was close in size to the 100W panel, and I didn't want to go to 200W for that reason. The difference is quite marked: I'm getting about 92W and 6.4Ah peak, and the battery hits absorption about 90 minutes earlier than the old panel. Overall, it seems that this panel gives me around 50% more power from a panel that is only rated 20% larger than the old one. I'm very impressed.

Quite nice product. I hope it works as advertised
