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

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.

The panels came in damaged. Easy to install, the size of the panels were as expected. Connections are easy due to using standard connections, pre wired . Power output is still being evaluated at this time, have not had the opportunity to really get into the max output capability yet but the panels have been providing constant wattage so far. Renogy customer support was amazing

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.

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 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 panels work well. I tested the outputs before installing on my Travel trailer. They have been working reliably since my purchase this past spring ( 2019) I made my own tilt brackets, but in the end did not save any money over what Renogy was selling theirs for. Tilting the panels makes a huge difference. You cant always park in optimal sunlight positions, so I tilt 2 for the morning sun and leave 2 flat for the noonday sun and my batteries are completely charged by 1-2 pm. I have 4 100w panels and the option to plug in another 2-100w 'on the ground' portable panels if the days are a little cloudy, with 4 Trojan T-105 golf cart batteries. We were out for 2 weeks at the end of July on the Sunshine Coast in BC and never ran our generator once. We ran our countertop ice cube maker with ease and could also run a 900w electric coffee machine. The panels didn't take long to charge our batteries back up. One note, as I have learned and doesn't really have much to do with the panels, but it's the Puekert effect on Lead Acid batteries. The coffee machine sent my battery monitor into fits with Low Voltage Alarm. 900 watts is a large draw for lead acid, which they are not too happy with. They do bounce back rather quickly, just be aware. Took me a day or so to figure that out. However my batteries don't suffer any ill effect, and the only way to mitigate that is to buy Lithium batteries, which are very expensive, but do not care about larger voltage draws. The solar panels are great.

Renogy has already got a great reputation, but living in the UK northeast we don't get the best of weather so I was thinking how much I would get out of these panels. Since I mounted them to my van roof (my stealth camper van) it's done nothing but rain and now its snowing lol. So with no sun at all in the sky I am still getting around 10-15 watts from the two panels, which is enough to run my interior lights or trickle charge the batteries. So maybe its a little to early for me to review but on a average day I am confident these panels will perform well. I think for the price you really can't go wrong, I didn't want to wait until summer to buy these in case the price goes up. I will review them again when I get some sunshine :) I think my advise is make sure the panels don't have any shade on them and buy a good charge controller otherwise you wont get the best of of these panels.

【購入理由】 自宅から離れた場所にある作業小屋で､新規100Vを契約し工事費・年間経費を考えるとソーラー発電は有効と考えていましたが、はずれソーラーパネル情報(この後はパネルと記載)のレビューに躊躇しながら３年､考えに考え100W Sunpowerが本命でしたがはずれ品や初めての自作システムなので配線ミス・設置じの落下等で壊す可能性等を考慮し、価格の安いこの商品にしました｡ 【価格】 他店の商品よりは高い価格設定ですが､届いた商品の品質は良好で価格相応とおもいました｡まあ､贅沢を言えば運送料がもう少し安くと端数はなんとかしてほしいです｡ 【大きさ】 寸法等記載がありましたが､実物はかなり大きいです｡設置の際注意が必要です｡ 当方では､設置位置･いたずら･飛び石等の関係で高所(単管パイプでベースを製作し高さ230㎝部)に設置したので大変でした｡ 【性能】 当方では､コントローラーに㈱電菱 SA-BC20､バッテリーは価格と入手しやすいＧＳユアサ GHC-40B19L(R)を４個並列接続でLED作業灯（24W×3個･18W×1個 個別ON・OFF可）を点灯するシステムを作りました｡システム完成から１カ月ほど運用していますが現在かなり余裕の運用です。 発電効率はかなり良さそうです｡曇りや日没まで発電ランプが点灯していて現在の使用状況ではほぼ満充電表示がでています｡100W Sunpowerパネルだとどうだったんだろうかと期待してしまいます｡ 【設置･取付のしやすさ】 当方は設置場所が悪条件のうえ､１人作業で強風の日だったので大変でした｡２人作業が理想です｡ 【配送･梱包状態】 配送対応は早かったですが､発送連絡メールに佐川急便集だん(だんの字は中国語？)と記載されていたので､中国からの発送かとあわてましたが､追跡サービスができるようになって確認すると発送元が日本国内の関西地区からの発送(会社名が異なる)となっていて問題なく配送されました｡梱包状態は普通と感じましたがもう一工夫あればと･･･｡ 【感想】 良質なパネルが購入でき現在安定運用できています｡今後はインバーターも考えていますので同一商品か100W Sunpowerパネルの購入による２枚パネル発電も検討中です｡ あと､耐久性を見ながら追加レビューできればと思います｡ 以上の内容から満足度星★５点です｡ 個人的な意見･感想を沢山書きました｡少しでも購入の参考になれば｡
