Renogy ShadowFlux Solar Panel 200 Watt, N-Type 25% High-Efficiency

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.

Installed this unit on my boat to support a 3000WH LiFePO4 house battery bank (12V system). It is installed hanging over the rea of the boat from an arch. Paired with Victron MPPT controller it consistently outputs 800WH (overcast) to 1200WH (full sun) per day. Great value for the money and consistent power out.

These pannels are absolut beasts. I have 6 on the roof of my rv and even on cloudy days, and I mean completely overcast, I've seen them draw upwards of 600W. Solid build, strongly recommend over regular 200W pannels

I love my panel. People talking bad about durability but mines 8 months old been backed into by a truck and my dog is always trying to mess with it still works great. Usually pulls between 155-180 watts in Florida sun with the heat. I personally recommend it. You can go cheeper but I like the fact it pulls the watts even in the shade when my 100w off brand can't.

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 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.

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.

Quite nice product. I hope it works as advertised
