Renogy 120W ShadowFlux Anti-Shading N-Type Solar Panel, 12V/24V System 120 Watt Solar Panel 25% High-Efficiency, PV Module Power Charger for RV Marine Rooftop Farm Battery Off-Grid Applications

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.

Great Solar panels, put out more than rated. Shadows not a problem anymore.

Works great! Hooked it up to a Bluetti AC180 and at one point was charging at 205W! Super excited how well it works when the clouds roll in or when positioned at a less than optimal sun angle. Still pushing a lot of power, I ran the power station down to 18%, hooked it up to the solar panel and within 4 hours it was above 60%, on a partially cloudy day, set at about 35 degrees! Not bad for 1x 200W panel, or I didn’t think so. Solid construction, easy setup after I bought some adjustable supports.

I bought this panel together with a charge controller from the same company. When testing I found that less than 50% of the solar panel output was used for charging my 12V LI battery. 1st and 2nd level support didn't help to solve the issue. Doing my own research I found that this panel has unusually high optimal output voltage of ~28V of which the PWM charge controller can use only about half (~14V for LI battery), hence the 50% power output cut to the battery. Other, cheaper panels have optimal voltage output of about 18V, which would allow higher percentage of solar power being used to charge a 12V battery. You'd need a more expensive MPPT controller, which does a kind of DC to DC power transformation to work with this panel efficiently for charging a 12V battery. It is disappointing that neither the product description mentions such limitations nor does the product support representatives seem to know such limitations and how to address them (buy a MPPT charge controller).

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.

Product arrived fast abd in good shape, installed and work great, would 100 percent reccomend for anyone looking for a great 200w solar panel, cable leads are not as long as i expected but still works very well!
