Interesting to see that you also fell for the MPPT scam. The one shown in this video is actually not an MPPT type controller. The MPPT on its case is the name of the company manufacturing these. How about making our own?

This panel can put out close to 100 watts ukposts.infoUgkxOqI2yqX0XVrhR2BMJciTWrHJpG8FhJyg 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.

Confession: I watch your videos just to see your hand drawn diagrams and listen to your pleasant voice! I maybe even learn a little along the way.

Ahh, thank you! There is so much garbage "explanation" about PWM vs. MPPT on UKposts... but you are the first I've found who explains what MPPT is.

i love how he says stay creative while breaking a solar panel :D

I did learn something new. Never knew what MPPT was, just knew it was baller. Thanks for my daily "Learned something new today"

I work with solar power plants for more than 5 years and haven't heard such a good explanation on the basics of the PV system. Thank you for this video.

Best explanation for the concept of MPPT

Your hand writing is fantastic!

Mom : What are you listening ? Me : UKposts classes Mom : Who is your teacher Me : GreatScott.....😜😜😜

Id like to thank you for re awakening my interest in both electronics as well as "making". Your videos are always fun to watch and usually spark the need in me to try out new things in electronics. So thanks for making awesome videos and i hope you will achieve all your future endeavors.

GreatScott Is a beast of an engineer .

love your work. Great presentation , one of the most succinct I've seen. I also love the use of fully analog diagrams (with a pen) to more effectively focus the student on the equations. Bravo

What an excellent intro to PV cells and their characteristics. Thanks!

oh yeah, your video come at the right time! I'm planning to make an air conditionning system for a tent, based on a Peltier module and solar powered. I know that Peltier modules are very inefficient, but for the application I don't need freezing cold temperatures or a big exchange surface. this video will help me to choose what components I need for this project, thank you!

Every time I see a new Great Scott video in my subscription box it puts a smile on my face. Thank you.

Amazing video. Simply, logically, straight forward to the point… to every point and every abbreviation along the way got explained too! Wooow! Man, I would wish to have teachers on all kind of schools as didactic, as you are!! Great job 👍🏻

I love your channel , every time I think of making a project . You release a video that is always related to it ! You're truly amazing

What a time to be alive! I wish such videos were available when I were in elementary school

Does anyone else pause GreatScott's videos to look for the items on Ebay?

I never heard of MPPT. Try what I learned in electronics college, Maximum Power Transfer. Basically the internal resistance loads are matched. This way of thinking has been around for decades before solar cells became mainstream and it really does work. Good work charting via real life measurements, though!

Thank you for explaining the MPP value and MPPT, I think with your explanation I now understand what the MPPT charge controller is doing!!

I get excited whenever Scott says "Let's find out!" in that pronounced German accent

I just had this exact topic last week in uni (I study renewable energies) and you explained it exactly the way our professor did, awesome (Y)

i am a Final year student of Electrical (power) Engineering and working on Solar Cooling System .i really liked your videos and follow you since your 2000 subs...Keep it up Brother...

understood everything this time . the content was nicely explained and easy to understand ....from INDIA

Very nice video, Jeremy. The timing was perfect, i just started making a solar powered wheather station, wich sends the data from my roof to a reciever at my electronics lab via radio waves. I thought of using NiMh Batterys as a rechargeable backup power source, but i think im actually going to try using super caps, since the requiered power is not that high.

Thanks for the detailed reference, circuit analysis and your precious time sir...

6:26 I love your curve fitting! :D

Brilliant explanation of MPPT... The only thing you didn't mention is that the MPP varies, depending on temperature and sunlight. Hence the need for tracking.

Even though you do not sound like a native English speaker, your diction is so good, that even relatively complicated concepts are easily understood by the listener. You do far better than most native English speakers, who, all so often on UKposts, you find, are not sure what they want to actually say. Complacency and some arrogance. I cannot thank you enough for the time you take to share all this knowledge and your sincerity in doing so. Thank you sir.

Very informative. It's great to learn those little technical details that make everything sense

I thought you were going to build an MPPT charge controller

WOW! thank you for the lesson. As always you provide good information in a compressed time frame without wasting any time. Keep up the good work. :)

Thank you Mr Great Scott. Your videos have always been informative, but I prefer your Electronic Basics and your "make" videos.

Scott. Your brilliance, like the led, is illuminating !

Yeah, it's here! So excited for this one.

I have an oral exam in semiconductor electronics tomorow so this came in very handy! thnx Scott, great video :)

i simply love these interesting videos. they teach me so much more than i could have learnt by reading books. . . .. keep up the good work :)

Always educational from where I'm sitting. Thanks!

Thanks Scott. I learned more in one video then I have in multiple others.

Your diagrams are so perfect. Are you sure you don't just print them out and then LOOK like you're drawing them? xD

always a pleasure Scott. outstandingly explained.

When you have no knowledge about electonics, but you still enjoy a well made video.

Hi! Dont know why this video was not recommended to me a few weeks before! It is a very interesting video on solar panel. And i am making a MPPT charge controller for my 12 V 10 W panel to charge a 12 V 1.3 Ah battery.

Your vids are always amazing. I click on them not knowing its you and happy every time. Keep it up!

Excellent how to video! Thanks a lot. Easy to follow and understand.

I imagine you could do quite a few videos on solar power management and some fun applications Fingers crossed!!! Thanks for the upload, Cheers

please make a diy mppt charge controller...

mind blown yet again, this channel is awesome!

That was the best short video I found on the topic. Tyvm

love it, good explanation^^ I've learn a lot about solar panels xD ,please continue of doing great things

I've used the 40a epever brand actual mppt solar charge controller for my shed, works really great. only 500w of panels charging a 200ah battery, which can run all the lights and even a mini server and NVR 24/7

Very nice Scott

Episode is very well done. I also enjoyed how you presented information via excel. Cheers

Thank you. Very informative. Can I ask you to explore a few Solar panel combinations: 1. No battery, Use the solar panel to run daytime electricity at home, limit peak day usage and then: 2. a Switch system that changes to using electricity from the Electrical Utility company as soon as the sun power decreases below a certain value. And 3. a switch system hat allows for sharing of solar panel electricity and available mains electricity. In this way we simply use the solar panels in conjunction with available power plant electricity to cut electricity costs.

ur circuit diagrams are awesome...

Once again, very informative video. Keep it up

It would be very nice to see a DIY MPPT charge controller! Hopping for it :)

good teoretical presentation

Awesome! I doubt it was due to my comment but I have been asking for this one. Perfect timing! :D

You draw ridiculously well. :)

You are literally a genius!!!

you're amazing, great scott.

Hi Scott, really nice explanation ! I actually waiting for a little solar panel to use with pwm regulator -> battery. Add second source of charging, like wind turbine is really complex, if you have a good solution for that, it'll be really interesting to explain :) thanks for your work !

Thanks for answering my question. I kinda wanted to see a circuit that tries to find the best power point, and the buck boost integrated into it. Basicly, a fancy joule thief in order ot use, not only low Volt/Amps of solar, but any other small power source, (IE, wind farm). Building a buck/boost to handle that kind of power would probably be impractical, but if you could show a joule theif/buck/boost that would send that information to a proper charge controller, that would be cool. Kinda like handing off the heavy load to something that can handle the heavy load. But, thanks again sir!

I once ordered a super cheap one. Don't repeat my mistake i all I'm going to say Nice video as always man

excellent explanation

I was hoping that you did a vlog about solar. thanks maybe a diy lipo solar charger vlog? :-)

great video man. thanks for all the wonderful information!

Great video again! Have you ever tried 'curve fitting' to your data instead of guestimating? Excel does it for you!

GREAT Scott as usual. =)

Great video as always!

Finally an interesting project :)

Thanks, nice and clear, I like the pen diagrams

very informative .. thanks for your effort

Outstanding !

Awesome as usual, but when are you formatting your pc and installing GNU/Linux? ;p Just teasing you. Thank you for all the time and attention you put into every one of your videos. I'm a big fan. Cheers from the hot central Portugal ;)

great scott!! i like your work and i want you to please make a video on rfid with arduino

you a genius bro! thanks for your videos!

Nice. I just studied about photo-voltaic cell technology last semester in college.

Great, Scott!

very well explained .

Thank you for the information.

Hey! I would like to see a good Class AB amplifier on this channel :D Keep the good work!

Great video I wasn't aware of difrence between mpp and nominal power. Could you present video about types of solar cells?

great video ! please upload another like this

I like it bro,keep it up

Well done

Great info very helpful. Thanks

I love u bro and your projects

Great video as always :)

Hello GreatScott, thanks for the nice video. I got the impression that MPPT controllers use more power than simple PWM controllers and may therefore be less efficient when used with small panels. Do you have any thoughts on that?

Interesting as always!

#GreatScott Great movie. I will be doing an MPPT converter in my project for university. But I will use the high voltage panels (50V) and low current (1A) and the MPPT will increase efficiency even further. I will use an arduino for control this device. When I finish I can also record a movie Greetings from Poland

Your videos are awsome!

It would be indeed a great one if you could make a diy mppt charge controller for solar panels. GREAT Great scott

Awesome video what kind of marker or pen do you use when you design your projects and where can you buy it

was that a 3D printed curve you used for tracing the line on the graph?

Awesome video, thanks!!
