Interesting that this kind of technology has been around for a while, but finally someone has put it into a foldable panel.

Very nice. I love seeing shading tolerance hitting the market. Great for travelling. Well done, sir!

I think it's always a good idea to have at least one shade tolerant panel. Also for anyone reading this - it says a 1 yr warranty and the 100w flex says it's waterproof - folding only water resistant.

Hey Jason thanks for your review, kinda thought the renogy would do better. Shade stopper is great for RVers 👍

Nice panels. For the price I would go with the flex panel. I would not mind getting the foldable one, but I just do not like the prices on them, that sale price is really good for a foldable panel that actually has diodes built in. I just do not see buying foldable ones for daily use unless you are full time in an RV or vehicle.

I expected 30W at the 100W Halfcut. 17W is crazy low. But this many Diods is a amazing the usecase of EV Roof installations. How fast does a tree blocking my roof PV... I love this new technology ideas. 🥰 Thanks for your presentation.

Thank you for introducing me to a new product. Very interesting. Also like that you added the CIGS to the test.

Man these could be super useful on my sailboat. right now I just throw 2 flex panels on top of my bimini but it often gets shaded from the mast, shrouds, lines, and all that. Thanks for the review!

Have 2 200 watt Cigs on my RV roof. They consistently put out very good wattage and they are walkable, so I don’t have to worry about breaking them (I walk on them often for roof maintenance, and the coating is very thick). I have been testing these for a year and they look new with zero issues . They have a ten year warranty and a 25 year performance warranty. So yes they cost more but I’m hoping they last longer than the cheaper panels. Also these come rolled up in a box and I don’t worry about shipping damage like with most other panels. They are easy to install and I’m going to cover the entire roof and have no issues with access. The only downside I see with the tape cigs is when they’re down, they’re down for good. For me thats a good thing and I like that U can’t even see them on my roof they are so low profile. My 2 cents.

Great information Jason. I'm in the process of replacing my agm batteries to lithium in the next 18 months on my class b rv. I was thinking of replacing the solar panels as well as they are beaten up pretty bad with the Texas heat. Was wondering if the shade flex panels fold enough to make the curvature design of the Ford Transit van, tough they are not visible from the front. Was not aware that the cig panels had technology similar to the shade stopper. Regardless of what happens in the next 18 months now I am definitely replacing the solar panels for sure. Might consider buying some for the yard also as I am surrounded by trees. Thank you for your hard work and sharing your findings with us.

Thank you. I had decided on benchmarking cigs panels moving forward because my application on a tiny cargo trailer build in the midwest that would only accommodate a couple solar panels and I need best efficiency as we've a lot of lake effect cloud cover. Everything else would have to be portable. I already own 2 160 W Folding ecoflow panels that I got with my Delta 2 Max. I was watching another of your videos and I was planning on Learning to wire them in series or parallel to take advantage of both solar imputs that max out at 500 Because I understand overpaneling from another one of your videos. My thoughts were to Go for a couple 400 W panels if I could make them fit to run all the time. And then when I'm in an area where I can. Put out portable panels I could run those two Into the same input in series. So I don't overvoltage and then use the other port to plug in my smaller portable stuff for an extra little boost. If the math worked out, such as on a less sunny day where i'm perhaps getting not much over half rated output from the nearly 800 potential. If I had 260 W panels in series plugged into the other. And I was even getting half of that. I'd still be getting well over a 100 W additional input for minimal additional cost/ effort

very nice, i would need to have this type of solar panel if i was gonna use them, as the sun moves around all morning long with the various shading elements.

I would go with the ShadeStopper. for my use in a offroad overland camping and limited space for traveling, a Folding Blanket style would be better. if they could make one like that.

Good Afternoon ! Thank You. TAKE CARE..

That's rather impressive. While I've been buying larger (200W) panels most recently, and plan to use one of your previous suggestions to get some higher wattage panels, I think for traveling it probably makes sense to have one or two of these.

Nice addition in my off grid rest house.

Great job on explaining and thanking for sharing!

Great video as usual. I have the Shade Stopper and the Cigs. Both are great panels. Will be trying the flexible one. Thanks for the discount.

I was hoping a company would do something like this! It's more affordable than a CIGs and performs pretty decently! Excellent!

My property is wooded... no wonder my 100W Renogy panel is barely enough for lighting (12V) my garden shed. I watched your Series vs Parallel beginner's guide figuring I was going to add another 100W panel. I learned for my application, partly shaded, parallel would be best. After watching this I'm thinking the shadestopper is what I need. Wish they were available in a rigid panel. BTW, excellent videos.👍

With similar performance, the real difference between the new panels and cigs are the flexibility and the cigs output resistance to damage. At their lower price, I can see these new panels do well as permanent panels on an RV roof and the cigs in more in temporary installations. Hopefully pricing comes down soon for this style.

Great technology! They should do very well in the market. Thanks for the test and the info.

Thanks a lot for this review. I will really consider the Shade Stopper for my solar panels

It is interesting that the CIGS panel maintains a higher load voltage than the silicon based panels under similar shading conditions. I wonder if they (Shade Stopper) are using germanium based bypass diodes to overcome some of the bypass voltage drop across a silicon bypass diode (0.6 V for silicon vs 0.3 V for germanium). This would be a concern when connecting several of these panels in parallel where most charge controllers will limit your current to 8 amps for voltage inputs of 13~14 volts. Even in series (or series / parallel for larger arrays), you may find that when shaded, the array drops the voltage below that 32~35 volt threshold where you actually loose even more power because the charge controller drops to a lower current limit. Thanks for another review of an innovative product! PS I hope you are going to be reviewing the upcoming EcoFlow Delta 3 Pro, which looks to eliminate all of the flaws with the Anker F3800, which is still a great product. Hopefully EcoFlow gets the price right!

great overview ❤

Look like good panels. Too bad only 1 yr warranty which causes me to stick with name brand panels.

Good video!! Very helpful!!

Impressive!

I have 12 Renogy 200W flexible panels. While I was trying to figure out how to best mount them in a way to be adjustable angle-wise, I just wired them all together & laid them flat on the lawn so I'd get some juice outta them. What surprised me is I was getting more wattage for a longer duration than my flat roof mounted panels that are aimed directly at the sun... at least they are at noon. So I made a mount for them on the side of my house that allows me to change their alignment with the sun, but by doing that, their output dropped. It must be because when laying flat on the ground they have more exposure to the sun for a longer time than when angled correctly, which has a higher peak, but over an 8 hour span probably has less average exposure. Does this fit with what you know?

Very nice demonstration. Having "bypass diodes" across smaller groups of cells in series is commonly done for custom solar panels made for things like solar race cars.

You could have kept the area the same by cutting a 6*6 (or whatever)section out of s box and laying that down on the panel. Just for the next panels you test like this.

Wish more companies did this on the proper house style of glass panel.

Ordered one... Can't wait to get it!

I just get to know you channel and love it. Can you do budget options?

I bought two of the folding shade stoppers back in February, the price has about doubled since then. The Shade Stoppers won’t help you during overcast days, but are very impressive,as you demonstrated, with sunny skies but partial shade.

Very interesting review! As noted, the CIGS also beats every other flex panel with its incredible bend radius. I put the 200w one on my motor-home, and have to upgrade the charge controller because output is so high! Another comparison I would love to see is this new panel vs the Optivolt one that you tested. I would think that would be a true apples vs apples test! (Although I think you reviewed the 48v output Optivolt.) Now I am regretting buying two of the Renogy (private labeled by HQST). Oh well, they will be "fair weather friends!

Question-would these be consistent enough to power a 12v cooler at tailgates/softball tournaments/Cookouts? Never used panels before great review/information!

Do you have any idea what the efficiency drop off is if the panels are used in a hot climate like the South West U.S. in summer time at say 115 deg. F ?

Going forward, the only can you can use is that can of Great Value Green beans…gotta keep things consistent! 😂

Question. So if the voltage goes down to the mid 13.? Will that be able to put a charge into my lithium battery thru an mppt charge controller?

Can you recommend a tester for solar panels that shows watts and amps? Thats not too expensive.

Can either of the 100 watt panels (folding or non-folding) be stepped on occasionally without it being wrecked? My application is the deck of a 35' sailboat where shading from the rig is ALWAYS a problem so I would like to test it out, but sometimes it has to be stepped on to get to the mast or part of the boom. The glass panel panels with aluminum frames (like the Renogy featured in your video) that I have now are super tough and can take a step on no problem. Thanks.

you didn't say how much the renogy ridged full sun was

Does anyone make rigid shade tolerant panels for permanent installations?

Hi neighbor. I live in West Jordan.

❤❤❤❤❤❤😊😊😊

adblock is a must. invasion of those adds pathetic

Nice panels, but priced way too high!!!
