Renogy 200W ShadowFlux Anti-Shading N-Type Solar Panel, 12V/24V System 200 Watt Solar Panel 25% High-Efficiency, PV Module Power Charger for RV Marine Rooftop Farm Battery Off-Grid Applications

This panel is well made! Works like it should even in shade it was putting off 31w

The Renogy 200W ShadowFlux N-Type Solar Panel is a standout choice for anyone needing reliable and efficient off-grid power. One of the most impressive features is its quick charging capability—thanks to its 25% high efficiency, it delivers consistent power even in partial shade, making it ideal for RVs, marine use, and off-grid setups. The ease of use is another big win. It’s lightweight yet durable, and installation is straightforward with pre-drilled holes that make mounting a breeze. Whether you're a beginner or experienced with solar setups, this panel is hassle-free and highly effective. I've noticed faster battery charging times compared to other panels in similar conditions, and it performs well even on cloudy days. If you're looking for a high-performance, easy-to-use solar panel for your energy needs, this one is a fantastic investment! Highly recommended.

Edit February 2019: I have 8 of these panels now and they are all working very well. Original review below. I originally purchased the kit with one of these panels, a PWM charge controller (Renogy branded), cables and mounting hardware. I slowly built up a 12V 220AH battery bank, bought one more panel and bought 50FT of 8AWG Pv cable with MC4 connectors to run between the panels on the roof and the charge controller inside the house. I bought such a heavy gauge cable because I didn't know when I could afford to purchase an MPPT charge controller and I wanted to minimize my voltage drop (and related power generation losses). The system worked very well and I was seeing just over 200W of power generation at peak from the two panels on the roof which was expected based on what I read about these. This was in February of 2014 here in central Florida. During the year the two panels and PWM charge controller did a great job keeping the batteries topped off. The summer was exciting when the panels started having a peak output of 212W. The reviews that say these panels don't put out their rated power must be people doing something wrong or they just live far north where there may be a reduction in power generation. Fast forward to December 2014 I got a 3rd one of these panels as a present from my wife, which I installed quickly and hooked in parallel with the other two to the PWM charge controller. This turned out to be a bad idea due to the voltage drop over the 50ft run of 8AWG cable at 15+ amps. The voltage was too low to bring the batteries all the way up to full. Now in January 2015 I was able to purchase an MPPT charge controller, specifically https://www.amazon.com/gp/product/B007PHMSN8/ MidNite Classic 150. This allowed me to rewire the 3 panels from parallel to series, greatly reducing the loss across the 50FT cable. It also allowed the batteries to get topped off even in low sun conditions. Unlike with the PWM controller, on very cloudy winter days the MPPT controller would still charge the batteries where the PWM controller would just trickle in a very small amount of power. I have two inverters hooked up to the system. One is on 24/7 and is used to power small electronics like laptops. It is a https://www.amazon.com/gp/product/B001539B7O/ Go Power 175W. The other inverter is a https://www.amazon.com/gp/product/B004OU99UE/ Samlex 2000W Pure Sine Wave which is only turned on when I need more than 140 or so watts continuously, or the modified sine wave of the Go Power isn't good enough. I plan to buy more of these panels in the future, and recommend them to anyone. You definetly want to buy the mounting kit as well https://www.amazon.com/gp/product/B00BR3KFKE/ since it does a good job holding the panel to a flat surface while leaving just enough room for the wires and some air circulation.

These panels.say nowhere in Amazon's documentation that they are 38v panels, but infact are. Amazon claims they are 12v panels so I bought a controller rated for 24v thinking this would be enough to run the panel. Nooooope. They seem like great panels but have cost me time and money replacing the charge controller with one that is rated for 50v. As a result I can only give 1 star rating. FIX YOUR INFO!

These panels are great, good build, well supported by Renogy, and an extremely good value. I have many and have yet to have any trouble with their performance, build quality, or workmanship. They have stood up to all weather conditions in the Midwest without the slightest grumble. The leads are a good length, the connectors are of a good quality as well. Extremely happy with these panels. [UPDATE April 2018] Still no complaints about these panels. I have three solar arrays and these occupy one of them. The other two are Renogy's 24v 280 watt panels. All arrays are wired for 48v feeding three Midnite Solar 150 CC's into a 24v LFE battery bank. These panels hold their own to their 24v 280w cousins. The only difference is the 24v 280's begin producing usable power earlier in the day and hold out til sunset, while the 12v 100's need a little more light before making usable power. Otherwise, they are still rockin solid, and going strong. ;) ***Update 12/2018*** These panels are still going strong... no complaints about that. However... for the money you spend on one of these, you could do much MUCH better. Prices of the 60 and 72 cell panels have fallen DRAMATICALLY these past few years. You can easily get a 350 watt panel on special these days for less than $200 each (trust me, I got 2800 watts of panels for about $1800 a couple weeks ago - shipping included). I love Renogy - don't get me wrong - but as of the time of this update, they are not keeping up with the prices of the here and now. Renogy's prices have not fallen in line with the rest of the bunch, and as such until they do, I won't be buying any more Renogy panels anytime soon. These 100 watt panels are still going for about what they did a couple years ago, whilst the rest of the competition is now selling better items at an extremely reasonable price. Renogy, are you listening?? As for the panels themselves, I've not had a single problem for the past 3-4 years. They are still putting out the same power now as when I first hooked these up. They've survived all sorts of weather with no sweat. Do I recommend these? YES. But only if Renogy begins dropping their prices. Otherwise, I'd have to recommend SolarWorld or Hanwha. I will still find use for the 9 100D Renogy panels I have, only they won't be feeding my batteries at this point. The other panels will do that. Don't get me wrong - these are very QUALITY panels. I've called their customer service and it was EXCELLENT. However for 2018/2019... these are a bit overpriced now and I'm surprised Renogy hasn't kept up with the times. Then again, maybe 100w monos will not go under the $100 mark anytime soon? As for me, I prefer getting my 300+ watt panels elsewhere. If you are looking to start into solar, these are not a bad start by any means. If you want a lot of solar right away... look elsewhere. There are two solar and wind stores (one in MA and the other in AZ) that can accommodate you for anything more than 400w.

These have been installed for about three months and I have no complaints. My initial design with manually powered tilting with actuators seemed too complicated, so I opted to sacrifice some energy generation by installing with static angles of 10 degrees in opposite angles about 4"-7" above the roof. This allows rain water to run off instead of pooling and avoids leaves and other debris from clogging up underneath which could exacerbate heat build-up. Instead of drilling any holes I used Versa-strut, which allows both a 2-sided strip of Eternabond to adhere the bottom and also a 1-sided strip along the 1" brims for additional downward adherence to the roof, then applied self-leveling Dicor along the tape edges. Hard to imagine any of it will lift up.... time will tell, but out of an abundance of precaution I used 1/8" steel cables crimped from the panel mounts to the existing roof railing.

Update April 11, 2013: Because Amazon support partially resolved the long-standing issue preventing me from using my Renogy purchase, through no fault of Renogy. I am now able to give an accurate review of the panels performance. ---English--- I now own three of these solar modules with two more as a kit with a solar charge controller on the way. Both technical support and the quality of the items themselves are simply awesome! You're just not going to find solar panels of this quality at this price anywhere else. I own several brands with higher nominal capacities if I could trade them all for Renogy panels, I would. ---German--- Ich besitze jetzt 3 von diesen Modulen mit zwei auf dem Weg als Paket inklusive Solarladeregler. Sowohl die technische Unterstützung wie auch der Produkt selber sind einfach klasse! Nirgendwo sonst kann man Solarmodule von dieser Qualität zu diesem Preis finden ---Spanish--- He comprado tres de estos módulos solares, y un paquete de dos con controlador de carga está¡ en camino. Tanto el apoyo técnico de Renogy como el producto mismo son increí­bles! En ningún lugar se puede encontrar módulos de esta calidad a este precio. ---March, Unable to use/review through no fault of Renogy: I purchased two of these solar panels to add more charging current to my Existing 550 W array after I purchased a 200Ah battery on Amazon and the seller/manufacture of the batteries (not this seller) in question told me that I wasn't charging the battery enough,so I bought the product. After increasing the charging power from 550w to 750w, The 200 amp hour battery still doesn't produce 200 amp hours at the 20 hr rate. So Amazon sent a 12ah deep cycle motorcycle battery by Odyssey. Because the seller will not ship me the correct battery before I send back the Switcheroo he pulled. I know 12Ah only runs the LED lights at night. But during the day I can use whatever amount of current the panels are currently providing and I have a small buffer before any change in that means I have to change the load which is better than having absolutely no power at all. Unfortunately however I can't gauge how these panels themselves are adding to my array, The fact of the matter is until the rest of my order is sorted, the array will be incomplete and so I have to give it a neutral rating it will be edited once I can pair it with the size battery I purchased. In the interest of other people assembling solar arrays or servicing them, The reply that I got from one of the Escalated CSR agents at Amazon On Friday, March 15, 2013: "I don't mean to sound cold, but you chose to live off of batteries. That's not Bluegrass Wholesale's problem, and that's not Amazon's problem." Customer centric? Earth friendly? It sure doesn't feel that way! There's nothing wrong with living off solar and batteries, there is something wrong with cheating a customer and doing absolutely nothing proactively to make it right, at least one of the CSR agents was able to provide a 12 amp hour motorcycle battery so that I wouldn't be in pitch black darkness. Hopefully, Amazon will correct the issue so that I can provide a review on the performance of this panel.

I bought 2 200w panels, one panel arrived shattered so I contacted amazon & they sent another replacement and the two panels they sent in replacement were intact. So far so good, I am pulling 350w on average in phoenix in winter, 100w more than my 2 220w ecoflow foldable panels. Between the two products I really like how much more compact & lighter these panels are in comparison, & I don’t have to adjust as often if at all during the day. edit: I recommend buying separately, UPS told me they needed both panels I was returning in the same box & I had to spend $50 for a box to return something I didn’t break, panels I do have though work well.
