We often get asked by customers what’s the difference between monocrystalline and polycrystalline solar panels. Here’s a surprising comparison of the differences (hint: not as significant as you might think).

This panel can put out close to 100 watts ruclips.net/user/postUgkxOqI2yqX0XVrhR2BMJciTWrHJpG8FhJyg when positioned in the appropriate southernly direction, tilted to the optimal angle for your latitude/date, and connected to a higher capacity device than a 500. The built in kickstand angle is a fixed at 50 degrees. Up to 20% more power can be output by selecting the actual date and latitude optimal angle.The 500 will only input 3.5A maximum at 18 volts for 63 watts. Some of the excess power from the panel can be fed into a USB battery bank, charged directly from the panel while also charging a 500. This will allow you to harvest as much as 63 + 15 = 78 watts.If this panel is used to charge a larger device, such as the power station, then its full output potential can be realized.
This is what the internet is for - for me anyway. I can learn things at my leisure, hardly a book required, taught by people who know what they're talking about for free. Before the "net, I'd have to attend a special class somewhere at some cost, materials required. Thi was well worth watching as have been many others. Thanks!
This can all be summed up in one short sentence.
“The college of youtube”
Your video is brilliant, you are the first person I've heard that has quickly, clearly and concisely described the difference between mono and poly panels, well done and thanks. Just need to convince everybody now to start getting them on their roof tops.
All her vids are concise and informative
it's about time solar panels were explained in plain English. thank you alt e. and thank you Amy
Comparison is clear, informative and lucid. It solved many of my doubts on solar panels. Immense thanks for preparation and presentation.
Thank you for everything, Amy. I never got to speak to you as I came to the game rather late but I can totally imagine that you are missed by everyone. RIP.
She's late? How sad 😔
😢
I'm a real late comer on solar systems. Looking forward to educate myself. Thanks for putting this up.
Then go to Will Prowse
@@dirgesinthedark5637 Thanks will do!
This is the best quick comparison I've seen so far. Well presented too. Thanks!
Lets see, SHE deliberately left out the TRUTH. Poly produces MORE KWH per day that Mono. Why? Because Mono has to be pointed directed at the sun and or put on a tracker to get full output. Poly can be off up to 10 degrees to get the same power. Obviously they are over stocked in Mono so its the best thing since sliced bread now.
I see little evidence that Angle of Incidence has a meaningfully divergent effect on mono vs. poly.
If you have a citation for the claim I'd be happy to read it and revise my position if needed.
Digression: folks who strive for Critical Thinker status (as you indicate in your profile) generally avoid emotional language and groundless accusation, and try not to project motivations onto others.

Oa
yup, they'd make renewable doable
Absolutely excellent! Technical, objective, and fair comparison of the two technologies. Thank you!
A very informative, well presented video.
thanks a bunch, just the information i was looking for, short, precise, informative and to the point. Much Appreciated
Always enjoy your solar explanations. Job well done!
Thanks for a well done quick explanation. You definitely answered my questions about the different panel types.
Thank You Amy !
It was informative and exhaustive. Much appreciated.
Thank you for this very nice explanation!
There is a mistake made however at 4:00 to 4:40. The short-circuit current actually increases with temperature, hence the positive temperature coefficient. The open-circuit voltage decreases (much faster) and the overall power output also decreases; both have negative temperature coefficients.
Real real good presentation. I hope the videos on the other components are as good and clear. Thank you.
Nice presentation. Well organized and informative. Excellent delivery.
Excellent excellent excellently presented and very easy to understand. Great job.
WOW! Funny how things change. Good explanation, and thumb up for the video. Thanks Amy.
Thank you Amy! That's was as easy to understand as it was to watch!
Thanks Amy. Great video with good technical explanations and examples.
This is the best comparison information I've found yet.
Good Job and explanation made simple. I was leaning towards Mono.... over Poly..... but now I realize it's not critical to worry about either. Thanks for breaking it down!!! :D
I have mounted 6 mono panels (300watt eac). I m planning to add more panels. Can i combine them with 4 poly panels of same wattage? Will it affect over all efficiency? Or go for mono panels only. Here temp go up to 46c during summer.
You are in a location that would benefit from mono panels because of the extreme heat. If you can't get them, and have to use poly panels, it may be worthwhile to get a second charge controller to run the poly panels and not have them affect the mono panels. I suggest comparing the temperature coefficient on the datasheet between the 2 types of panels you are looking at. If the numbers are similar, it may not be a problem.

I had same question.
Thank you for answering!
Monocrystalline seems the way to go since I'm a big fan of taking solar technology and batteries to the next level.
To those interested:...…...I had a mismatched, 4,400 watt array that was Cooled by a single (Isolated) 12v panel hooked directly to a computer fan, drawing cool air from corrugated tube, just underneath the ground. Not needed when sun was at low angle, so no battery needed. It helped to produce more power during hot days, instead of common overheating losses.
Really nice breakdown of the solar panels and pluses n minuses
Great Post! Enjoyed watching. Thank you for sharing!
Thank you, Professor, for this valuable information
Thank you so much. this was so basic and clear!
Great video! Texas heat can stay over 100 degrees F for months, so it would definitely pay to use the Monos! Thank you very much!
Nice video, very informative. Thanks for making it :)
Thanks for this excellent explanation! Very clear and covered it all.
I love this video quick and pack pack with so much information. Thank you
I have mono panels and when I got them I tested them in the winter and they outperformed the giving data
2 years later they still outperform the giving data in the winter.
Is there any difference in longevity of life between mono and poly panels.
Sorry for the delay in response. That's a really good question. I reached out to solar panel manufacturers who make both types, and was told that there is no difference in the technology that would cause one or the other to degrade faster than the other. The National Renewables Energy Lab (NREL) has published papers on the different degradation rates of module technologies; the primary contributor to degradation between mono and poly is quality of manufacturing and material selection, not the cell technology itself. So it's really more about how they are made, not which technology.
Thank you very much for answering that question.
Very well presented. Thank you for this video!
AMY BEUDER GREAT PRESENTATION ON COMPARISONS,,RESPECT FROM PAKISTAN.
May thanks for the information .Very clear Presentation .
Great presentation. Love your work 👌
I have a 100 Watt Monocrystalline solar panel mounted on my RV roof. up here in the Rain Shadow on Vancouver Island, we get many cloudy, rainy days (even in the summer). I am quite surprised at the power generation I am getting on overcast days.
Amorphous Kicks the crap out of Mono and Poly
It was my understanding that amorphous panels are less susceptible to partial shading issues, but they are less efficient (lower wattage per square meter). Are you talking about low-light conditions? Have any data to back up your claim?
Mark Job d
Subscribed to excellent info. Presented for me to easily understand! Ty !
You explained it simply so evan I could understand, thanks.
She explains so well !! Thanks a lot ! ☺
Excellent information and so expertly presented thank you
Well done! Great tech easily explained. Superb.
Thank you so much for your clear and concise explanation!
Thank you, that genuinely cleared that for me.
Thank you for your video. Very educational.
Nice comparison of mono vs. poly panels. Both work great so long as you buy Tier 1. If you are space constrained you will want to go with mono because you can achieve greater energy density. But for most homes and businesses, poly will work just fine. Let's grow solar!
Hi Tim, what does tier 1 refer to? Thank you.
Tier 1 solar panels are built with higher standards (to last longer and produce abundant solar power) and have a highly regarded reputation within the solar industry for quality and service
if you say about the less than perfect light, does that include panel angle?
if I have a flat roof, would Mono behave ok flat on the roof (with brackets to lift off roof) than Poly?
Excellent. Well presented and easy to follow.
What a nice presentation!!!! Thank you.
5:54 Very Nice. Great video thanks.
Thank you for taking the time to explain :)
if temperature above 45 dg cel which panel is good Polly or mono
Hi,
your channel is great . i have question for you , In the part of the world where i am living the temperature in summer in average variesvfrom 35 c to 40 c in that reference to this mono and poly solar panels which one would be the best option?
In extreme heat, mono is slightly better.
Which one, of the two last longer, before they need replacement?
I really love this. Answered ALL the questions I have in mind and allayed my fears about Polycrystalline Panels. Thanks!
Is rate of degradation marginal between the two? I usually find mono panels with longer warranties.
Greetings from Germany! Thanks for enlighten me, Amy!
thanks is a small word for your great work. thanks madam
Excellent information. Thank You !
I like the way you are helping . love from Pakistan
So, on a boat in the hot tropics, clouds, and partial shading, the Mono would be a "little" more efficient on 3 different areas. Does the 3 little benefits add up to something worthwhile or just still a little difference?
Thank you for the objective presentation.
Awesome ! absolutely awesome
Can poly solar panel be mixed with mono solar of same wattage ? What be the affect ?
That was a great explanation!
thanks for this ive learn a lot
Do you need by-pass diodes if only using panels in a grid-tie situation? Or can you skip them?
If you are using a grid tie inverter or a charge controller for off-grid, you most likely will never need an external bypass diodes. We did a video on that, ruclips.net/video/5rYy0gHZepI/видео.html.
LOL @ Period! (4:59). Thanks Lady. I have 4 monos but haven't put them on the roof yet. I want to make them portable.
Any chance you can update the video ?
Thanks - that cleared that up!
I know this video is a bit old, but I live in a very hot city. Should I prefer polycristalline panels because of its color, meaning it would heat up less than the monocristalline one?
Great 👍 video, it was very informative and well explained it helped me alot thank you.
I need some solar panels! I don't guess it really matters if its pile of crystal or mono crystal. I will probably have to buy one at a time. I'd like 250w 24v panels . but may have to ho with 100w12v because of shipping. do you guys offer any deals that would help me . thanks a lot. I love this channel. I'm off grid and must get some panels. the gas generator to charge batts isn't good! thanks again.
2% more efficiency is ca. 12% more Power output, circa 17.5/15.5=1.12
That doesn't corrolate with the figures she gave e.g. 260W Polycrystalline vs 270W Monocrystalline>
I calculate a 3.7% difference in output power!! Go figure!
@@av6966 probably a bit more surface area on the poly, as the corners aren't rounded. But that wouldn't make up the difference.
@@ancapftw9113 I'm new at this but how did you figure this number number up? Thought if its 2% should be .02
I would stand by with what the lady said. It may be just the stupid talking out of me, same concept but other way around. Your car/truck battery, if its say minus 15 degree Fahrenheit and not been started for few days, your vehicle battery only had 2 different cranking amp categories. One is CCA for temperature is 32 degrees fahrenheit or lower and another section is CA which is temp is above 32 degree Fahrenheit. Can you guys take a guess what's the result would be those 2 sections in different temperatures? Cold temperatures will drop your voltage from 12 to 6 volt depending upon the condition of the batteries. But your amperage will go up. Chances are it's not gonna get it's full cranking amp on time because batteries just died on you. Above 32 degrees voltage will drop around 9 to 10 and still get almost full cranking amperage. My point is that there is some things that certain things will kill certain things effectiveness. I may be wrong, the hotter it comes, the more resistance it will form causing the best effectiveness to drop a bit. But hey 2% that's not much at all. Heck can fix that problem real fast, if it's a concerned, add another backup supply battery lol
@@matthewdavis7780 they are measuring efficiency differently. While the overall efficiency is 2% greater, it outputs 12% more power.
One is comparing the output to the ideal efficiency (100%), the other is comparing the panels to each other.
Think about it this way: If I have a 5 gal can for gas, but it only has a gallon in it, it's 20% full. If I add and another quart, it's 25% full. The way she's measuring it, that's a 5% increase, but I actually have 25% more gas in the can.
Many thanks , really useful comparison
can i use both monocrystaline and polycrystaline together? if yes, what wud b d impact?
Yes. The differences these days is so small, there should be no impact, provided they are both the same wattage and voltage.
I think just use what looks good to you either the color or the performance.
Thanks for the video.
Nice job Amy it looks like you love what you do which is good
Which one lasts longer on average? Or is that determined by the manufacturing quality only?
Great quick clean explanation
Great job.
great explanation thank you. I especially liked the image of polycrystalline.
What about longevity? Does one type tend to last longer than the other?
Thanks for not wasting my time with a lot of unnecessary babble. Clear and to the point .
Clear and concise. Thank you.
Hello miss.
Here we have two months of extreme cold with fog.
Two months with extreme hot with 46 degree centigrade temperature.
Two months with rainy season.
Which type of solar panel we install???
2 poly and 2 mono series of 2 then parallel. and be happy 😊
How can one video give so much information. Awesome Explanation
thanks Amy. well understood
It is mentioned that the manufacturing processes cost different amounts. How much specifically do they cost?
Is there is a difference in energy production between monocrystalline and polycrystalline under overcast conditions?
+Ommmm Mono panels can perform slightly better in overcast or hazy conditions. But again, the performance difference is very slight, and varies between manufacturer's, so one manufacturer's poly may perform better than someone else's mono, depending on their manufacturing process.
Amazing explanation. Thank you a lot
What do you suggest if during part of the day you have PARTIAL shade moving across, like from a power line of small tree branch. Not enough to block an entire panel, but maybe 20% of the panel at a time. Mono or poly?
+SkyCNG Both would likely be affected the same. You may be better off addressing it with the equipment you use, with separate charge controllers if off grid, or microinverters or DC optimizers if grid tied. This will help prevent one panel from negatively affecting the other non-shaded solar panels.
+altE Store the question is : Mono or Poly... All other answers = politician way of lying.
+Kalvin One I respectfully disagree (ok, that sounded like a politician). There is not a black and white answer to the question. What if they can get a 120W mono panel and a 130W poly panel for the same price? Which is better? What if they separated the panels from each other with a diode to prevent the shaded panel from interfering with the others (see our video on diodes at ruclips.net/video/5rYy0gHZepI/видео.html) ? What if the efficiency of one brand of mono is lower than the efficiency of another brand poly? There are lots of variables. And once again, the differences between mono and poly are so small these days, except for extreme instances, it really doesn't matter. So while there may be a precise scientific answer with all of the variables filled in, it may be so small of a difference, it doesn't matter.
So which one is the best among the two for home
Good Job and Nice explanation
in a very hot conditions like in asia ..46 degrees in summer which one is better...??????
The only thing not mentioned was longjevity of the different panels. What is the expected lifespan of each panel??
I have heard mention that mono-crystalline is more effective where partial shading of the panel might be of concern. Specifically, that if a poly-crystalline panel is partially shaded, the output of the entire panel (i.e., even the unshaded part) is significantly reduced, while for the mono-crystalline panel, the output of the unshaded portion of the partially shaded panel is unaffected. Can you either confirm or debunk that claim?
+Peter K. I can debunk that claim, absolutely. Mono and poly solar panels are both wired the same way, and with the same material. It's just the way they turn the silicon into cells that is different. They are both affected by the sun, and lack of it. The mono may be ever so slightly less affected by shade, but they are still affected none the less.
I'm running out f good weather for the year, but as soon as we get sun in Massachusetts again, I'll do a demo comparing mono and poly outside in the sun to prove my point.
Thanks for a very useful video
