Renogy 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.

Mounted on my Toyota Sienna easily with common mounts. I have seen it charge as high as 216 watts on good days I use it to keep my Bluetti AC180 charged and it works great. It's been in use continuously for 10 months and has done it's job as expected. I had 1 week of cloudy skys last summer and had to charge my power station on household current but other than that is has kept up with my needs. I'm glad I got the Shadowflux. I spent a lot of time reasearching solar panels for Van Life and this one would suit most people's needs. I run a refridgerator, house lighting and do most of my cooking on induction cooktop. The combination of the Bluetti and Renogy solar panel have been a good match for my needs. The only probem I had was the included cable broke but that coulld have been my fault. Carry a spare panel to solar generatior cable just in case

I have been running 4 of these panels (wired 2S2P) for a total of 480w on the top of a Sprinter 3500XL RV for 5 months now and am super impressed with their performance in all weather conditions. When the sun shines, they consistently approach their max capacity (80%) and stay above 300w. But the great thing is their versatility: they produce 100+w even in cloudy conditions where my previous flexible panels would hardly produce anything at all. I have not needed to run the onboard generator for my 420ah LiFePO4 battery bank since I installed these panels. Installation was fairly easy on my DIY superstrut roof rack system with bolt down clamps; they are firm even after driving across the country from FL to AZ. These have been a great value for money and very durable, especially when compared to flexible panels. I expect these to last much longer than I plan to own the RV.

While I was pleased with the performance of the panel, the glass suddenly shattered while installed on a Minute Man stand. I requested warranty service from Renogy and was told the manufacturer’s warranty “only covers damage identified before first use or damage that occurred during shipping”. That’s not a warranty in my opinion. I will continue using the second panel I purchased, but will never buy anything from Renogy again, and I urge everyone else to think twice.

Amazing new technology and weathering the storms great after a year or so - huge boost in power

Poor customer service, Renogy website not working, unable to register the panels for warranty coverage. The panels are nice, smaller and lighter than the ones I replaced which made the job easier. Price good only when they are on sale.

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.

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.

Quite nice product. I hope it works as advertised
