ShadowFlux Solar Panels, N-Type Anti-Shading Panels for 12V/24V Systems with 25% High-Efficiency PV Modules, 200W ShadowFlux N-Type Panel

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.

They work great!

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 use this panel to charge a pair of 12V batteries wired in series. The panel connects to the batteries with a Victron charge controller good for 15 amps and 75V. The panel is as described. It is rigid and mounted in an extruded aluminum frame. The frame has numerous holes in the back face for connection to supporting structure. The standard solar plugs are clearly marked for polarity. The panel is heavier than I expected - almost 16 pounds. I can say with confidence that the panel is charging my batteries but I cannot vouch for the exact power output. An important distinction of this panel is that it works well is uneven illumination. My panel is in the shade of open trees for part of the day. The dappled light that gets through is used by the panel. I will buy this panel again if I have a similar application.

Wish it had mounting brackets with it

Installed in fall 2025 and they're working great. The initial design with powered actuators tilting the panels to optimize power generation got too complicated, so I compromised by installing static angles ± 4"-7" above the roof which allows rain run-off instead of pooling, and avoids leaves and debris from clogging underneath which could exacerbate heat build-up. The RV's got a great rubberized roof, so if anyone's interested in a no-drill-holes solution: I used Versa-strut instead of standard strut channels, so in addition to the double-sided strip of Eternabond tape adhering the bottom of the strut to the roof, Versa-strut also has 1" brims on each side to allow additional downward adherence, and then applied self-leveling Dicor along the tape edges. Hard to imagine any of it will lift up altho time will tell, but out of an abundance of precaution I crimped 1/8" steel cables from the panel mounts to the existing roof railing to avoid leaving any smashed windshields behind me from free-flying panels. I had tested standard (non-shadowflux) panels a while back, and I believe these panels help to optimize power production.

Solid! Smaller and lighter and more powerful than prior solar panels. Work well when partially shaded. I haven’t been able to generate all 200W from my single panel yet, but even 160-180W at full sun is great for me. I installed one panel on the top of my Four Wheel truck camper with 1 1/2” aluminum angle brackets to the Yakima roof tracks. With the right hardware, mounting went well. I had tight clearance to the solar plug on the roof, so needed a right angle adapter to fit the panel and the wires. The panel seems durable enough to withstand vibration and wind, but time will tell. I like the black border and style of the panel.

All of Renogy's products are superior but these are the best of the best when it comes to solar panels. I bought for the roof of my RV and will update once installed. Campgrounds frequently have light shade or imperfect conditions for solar but these optimize the sun you have and don't shut down because there is a partial shadow or blockage of sunlight.
