New Shading Technology! Testing the Renogy ShadowFlux 200w Solar Panel!

[@segundacuenta726]

Wow, very nice technology. Expensive, but very good advancement. For people with very limited space, this is a very interesting option.

This is what I've been waiting for! I've currently got around 1200W of deployed solar on my sailboat but shading is a massive problem. Two masts, rigging, and equipment aloft constantly shade various panels throughout the day, and I generally see less than 4kWh of production on a perfectly clear day near the equinox. I wouldn't be surprised if these panels net a 50% increase in production. I'm maxxed out, space-wise, but 6kWh could pretty much meet my entire electrical demand and allow me to spend weeks at anchor without running a generator.

Great video! I think a lot of us deal with partial shading at some point in the day. This panel appears to to resolve this issue quite well. Would probably have to run them in a series/parallel config to keep that VOC in check, but not a big deal at under 7A per panel. And that footprint for this 200W panel is amazingly small in comparison. Thanks for the review on these- Happy New Year!

Not quite as good (for shade tolerance) as the CIGGS panel but better than pretty much anything else at about 40% of the price. Great review and demo of the shade tolerance. I wonder if another KZbin reviewer will shoot it full of holes and run over it with a quad:) TOPCON cells are made from n-type (doped) silicon where as most others (silicon) are p-type silicon, which is typically more expensive. They typically do better in space and are more tolerant of radiation damage. I guess enough nerd! Thanks for reviewing them!

The winter shading is destroying my solar gains. I have 1800w of panels and on a good day i am getting about 1700wh for the whole day. I like this new renogy! Jason, any chance you have 2 of the shade stopper panels? Would be cool to see a shadowflux VS shadestopper (2in parallel) VS comparable bifacial with at least 10bb and halfcut cells.

[@Firephosure]

These new N-type panels are amazing. I have a couple of them. This is great for van life where size is a premium and the shadow effect. For home usage, still too expensive for the usable wattage per $1. I mean I can spend $90 for 150w usable wattage vs $219 for 195w.

[@Jasonoid]

Great points! Usually space and shading performance are very important in a portable setup so that's what these are aimed for. If you are going big, pick up some 400w panels for $150 each.

Impressive performance. Just curious, if you shade a whole row (top to bottom), does is still perform well? Just was curious if they were connecting the cells in a way that might impact that kind of shading more than the left to right shading. I have some rough shading in the winter months for the ones on my shed due to some neighbor's trees.

[@Jasonoid]

Great question, I'll need to test that type of shading. If you look on their website it seems it performs well in that type of test too.

[@aulii11]

That's pretty impressive! I'm definitely interested despite the initial price.

[@Jasonoid]

If you have a small project that's going to be in the shade, these panels are a great option. For a larger project without shade, stick with traditional 400w panels.

[@ChrisSgaraglino]

Awesome test. Not every solar panel can be mounted at the optimum angle, which we all know angle can also reduce output. An example would be on top of an RV, where most have to be flat. I’d love to see a test between the two panels at different angles (flat to optimum) and see how the two compare and performance.

[@joedirt1955]

Oh man, I’d really like to know if shade tolerant panels are better at non-optimum angles?

[@michaely1164]

This looks like a very impressive solar panel especially if it can be purchased for the sale price. I'm a home owner that has to look out for shading and this is the best option so far both for the cost and especially the efficiency. Would be nice to have a little bit more testing particularly when shading. What wattage would you get when shading half the panel in the other direction (lengthwise)? Knowing that value would probably have me order a number of panels instantly. Thanks for the review Jason!

[@Jasonoid]

Current 400w panels have two halves, one 200w panel on top, one 200w panel on bottom. If you are only shading the bottom or top of the panel you'll get an okay shading performance. Vertical shading you'll lose most of the power. The 400w panels might be more cost effective for your project.

[@kyfeam]

So as long as you dont have a shading issue your fine with the regular panels.. 2-100w Renogy panels run about $166 with another 30% coupon on top of that.. we live in Nevada.. so shade isnt a thing around us lol.. still a nice panel though..

[@Jasonoid]

These also take up less space so you could technically install more of these panels in the same space. The main advantage is shading performance though 👍

[@heroofharo]

What about the impact of dust build up? I bet these would perform a lot better than standard panels even in the desert where shade isn't an issue.

[@heroofharo]

I'd love to see it kind of shaded by leaves. You know the kind of patchy moving shadows where some light gets through? I'd want to put them on the roof of my little shed/cabin set up I'm planning so I can visit my mother more often. Her yard/property is surrounded by trees, I'm sure I can angle them in a way where I can get a few hours of good clear sunlight, but most of the day will probably be partially shaded at least.

[@californiamusic]

Good stuff.. thanks!

[@shelley131]

I love the panel. I have a lot of shade trees in my yard and this could help me from chasing the sun when I use my units . I have the generation one EcoFlow Delta Max 2000 units so have to watch the voltage. Do you know if connecting them in parallel would offer more or less the same results?

I don't agree the solar panels are a good price. Maybe considering the shading thing, if you have no other choice, but for most people you can buy good solar panels for .22c-45c per watt easily(excluding shipping). Now if you want less than 10 panels, specifically just 2-4, this might be the only case this is a better option for you.

These panels are meant for a smaller application where shading is an issue. Think of an RV, sailboat, shed roof, enclosed trailer or other similar installs.

[@shooks555]

@@Memyselfandionyoutube I agree, love to see an overcast test on this panel.

[@persistentone3448]

Could you do another video where you test the ability to work on an overcast day? You could set up a light panel on a day with intermittent overcast and try to measure output based on the lux reading at the panel. Then build your summary table based on the lux readings and corresp;onding power outputs. My guess is that this panel will operate with more overcast than other panels. Understanding if we can get even 1/10th of the rated power on a rainy or overcast day would be a big deal.

[@Jasonoid]

Normal solar panels produce 10% on an overcast day, I have a bunch of these panels I could test with in a different video.

[@persistentone3448]

@@Jasonoid So I am guessing Shadowflux might produce 30% in the same conditions. That would be a very big deal to report

[@chrissinclair8705]

That's extremely impressive. For some of us with postage stamp sized backyards this would probably make a good option. Especially if you are in my situation where a pesky little tree branch at certain times of the day, is killing half the wattage. I would love to see a foldable option. Doesn't have to be in the 200w range necessarily, but say in the 120w range perhaps? So it's small enough that lugging it around say in the back of your car or whatever is not a big problem, but it still gives enough power that you can charge a smaller power station or ebike battery in my case would be totally viable. I live in little Italy in Toronto so I'm already disadvantaged latitudely as it is pretty far north and every one of the neighbors has a lovely tree or grapevine or...errr..."shrubbery" that is totally legal in Canada but maybe not in the some of the States so much. So when my hippie neighbor(great guy) has his "shrubbery" buds in full bloom I get a bit of shading. However the upside, is he's very generous with his "shubbery". Maybe that's not a video I can put on my tech channel.

[@Jasonoid]

I think they have plans for a future 120w version, wouldn't be a portable panel though, similar to this glass design.

[@chrissinclair8705]

@@Jasonoid That's still a viable option. I was impressed with the weight and size.

[@stacyhackney6100]

Thx u

[@steventrott8714]

Would power optimizers yield similar results?

[@Jasonoid]

Power optimizers are designed for larger home grid tie systems using larger 400w panels. I'd say these Renogy panels are meant for smaller portable setups. I haven't tested DC optimizers in this type of situation.

[@litnoregrets7551]

Thank you for the review Jason and making me aware of this new panel. For me this panel wins because of the three factors you mentioned: shade tolerance, size, and cost. If it had done poorly in any of the three, it would probably not be worth talking about. These three make it a viable candidate to use camping on my car. For home use, it needs to compete with my Renogy bi-facial panels. Cost is slightly higher for this panel, size is not as much a factor, and shadow tolerance would be nice but is it better than having bi-facial? This is just a rhetorical question. You asked what I thought. 😂

[@Jasonoid]

In most cases bifacial panels don't add much power. You have to have the bifacial panel mounted high above the ground to see any significant gains. I'd rather take the shading performance in my use case, I have to deal with lots of shading.

[@cmac3530]

I'd be interested to see if it matters which cells are covered. For example, would you get more out of it if the top/bottom half was shaded vs the left/right half?

[@Jasonoid]

It's hard to test every scenario in a video like this. When the average view duration is 3 minutes I kinda have to be brief lol...

[@douglasmontgomery6315]

Jason, now that someone has developed a "shadow resistant" silicon panel. Could you compare the 200w CIGS BougeRV to this panel. Size, weight and shading. output over a complete day (not just a certain time of the day). reason I say this is others have compared CIGS to SILICON and made comments that a CIGS panel starts outputting earlier in the morning and later in the afternoon vs silicon...so output over the day, week..month is as good or better than mono over time..plus the shading benefits. I know at the end you compared cost vs CIGS, but size and more importantly weight/portability of CIGS might be a benefit to some. Thanks

[@Jasonoid]

I'll consider doing another shade testing video. My previous video comparing the CIGS panel to other options got hardly any views.

Hey Jason, do you think you could get away with installing 2 of those panels in series and connecting to your delta 3 plus? Or are you sure it would be over voltage (assuming 60v max rating)? (I haven’t learned yet which numbers I need to know when adding together for series connection.)

[@Jasonoid]

You can't connect two of these together in series, the voltage would be too high (over 60). You could connect two of them in parallel and you have about 31v @ 13 amps for 400 watts. Just make sure you use the XT60i MC4 cable to get the peak amperage.

In order to get bifacial gains, your solar panel needs to be mounted 10 feet high off the ground, or mounted vertically. Bifacial solar panels are a little misleading. I have three bifacial panels mounted on my shed, they see no benefit over my normal panels since light can get behind them.

You can connect four of these 200 panels in PARALLEL for around 800 watts charging on each port of the F3800. Connecting five panels won't give you much more power due to the voltage and amperage limits on the power station.
