Excellent. Well presented and easy to follow.

Thanks

Thank you, that genuinely cleared that for me.

Better call saul, i like her.

Great video

This lady is a natural born communicator, her style of presenting the differences between these two types solar panels is absolutely exquisite. Oh, and she has fabulous hair as well. Whatever she’s paid, it really isn’t enough.

I understand where you get the 2% difference, but my math says that the 17.5% mono panel is actually 12.9 % more efficient than the 15.5% panels.
2÷15.5= .129 ( or 17.5 ÷ 15.5 = 1.129) expressed as a percentage as a 12.9% increase. Love your videos, looking in to getting some solar for our RV. Thanks!

Good Job and Nice explanation

From the test I've seen poly is better

Real real good presentation. I hope the videos on the other components are as good and clear. Thank you.

Not to be too technical but 17. 5 is almost a 13% gain from 15.5. what is more important when comparing panels is % of gain not overall efficiency….. Did I do my math correctly? Lol's Great info on this vid, helped clear up some things for me…

Absolutely excellent! Technical, objective, and fair comparison of the two technologies. Thank you!

May 9, 2020 at 6:07 pm

101% for the presentation, thank you.

One thing that she didn't mention was the difference in lifespan. That could be a selling point for some people.

I love Amy <3

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.

mono win?

May 9, 2020 at 6:07 pm

Many thanks , really useful comparison

May 9, 2020 at 6:07 pm

What about the claims that if a monocrystalline panel is shaded in the shade it can stop the whole system from charging?

May 9, 2020 at 6:07 pm

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!!! 😀

May 9, 2020 at 6:07 pm

i hope you can enlighten me, since this video was made year 2015. thank you

May 9, 2020 at 6:07 pm

good day or night, mono is more expensive and higher wattage , poly is cheaper but lower wattage, then which of the two is more durable? which of the two will last longger in time ?

May 9, 2020 at 6:07 pm

How about constant daily temperatures of 40+ how much power would we lose? Actually I would have thought the more sunshine the more power. I was wrong again. DUH!

May 9, 2020 at 6:07 pm

So basically it doesn’t matter which you buy you still gain the same efficiency.

The only difference is mono has higher watts

May 9, 2020 at 6:07 pm

my question is….How do you get so much volume in your hair!?

May 9, 2020 at 6:07 pm

THESE PEOPLE MAY NOT HAVE ACTUALLY TESTED WHAT THEY SAY..

IT TURNS OUT IN
REAL WORLD TESTS OF SAME WATT PANELS TELL A DIFFERENT STORY..

IF YOU HAVE TWO PANELS BOTH 100 WATTS ONE IS POLY CRYSTAL AND ONE IS MONOCRYSTAL THE POLY CRYSTAL PANEL WILL BE SLIGHTLY BIGGER AND WILL GENERATE ABOUT 10 WATTS MORE AND WILL BE BETTER IN VARIABLE LIGHT CONDITIONS ALSO,
THIS IS MEASURED TO BE TRUE

STOP!
Most of the planet are using the wrong Panels!
If you don't track the sun daily, if your not going to change the angle seasonally or if you have a decent amount of overcast days and if you have a bit of extra space then the best panels are thin film. Most of the northern hemisphere are using mono or polycrystaline panels which are no good unless you live at the equator or unless you track the sun throughout the day and the year.
The panels that everyone uses only work well when aligned into the sun and are completly unobstructed from shadow.
Thin film panels will work in low light levels which includes sunrise sunset, overcast days partially obstructed by shadow and unaligned panels.
So unless you track the sun you are only getting a decent amount of power for 4 or 5 hours a day for half of the year.
Thin film will give you full power all day all year long!
If you have a little more space and can invest a little more initially you will soon recover your costs and more!

They are BOTH the same in performance.
