In this episode of Electronic Basics I will show you how solar panels are wired up, why bypass and blocking diodes are necessary when working with them and how we can get the most power out of them. At the end I will also show you how MPPT and PWM charge controller can use a solar panel to charge up a battery.

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?
I have not tested the charger yet but I thought that it was not real. That is why I did not feature it that much in the video.
GreatScott! This summer I will probably start the project of the electric longboard you made the last year. I also learned something during this video nice one ! ✌️
What? They named their company MPPT? Is this even legal?
Welcome to china
you can actually make a mppt charge controller using arduino look this up at instructables
This panel can put out close to 100 watts ua-cam.com/users/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.
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.
I like it :-)
William Garrett same here :)
William Garrett Same here. Also, his videos are easy to follow and much more interesting than "view bait DIY videos".
they are the best!
i love how he says stay creative while breaking a solar panel :D
R.I.P Solar panel
He RIPped through that solar panel.
Stay destructive?
That's called creating a mess.
nedelas nahodou v AUO site Brno ?
Ahh, thank you! There is so much garbage "explanation" about PWM vs. MPPT on UA-cam... but you are the first I've found who explains what MPPT is.
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.
I did learn something new. Never knew what MPPT was, just knew it was baller. Thanks for my daily "Learned something new today"
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 UA-cam, 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.
What a time to be alive! I wish such videos were available when I were in elementary school
Best explanation for the concept of MPPT
What an excellent intro to PV cells and their characteristics. Thanks!
Every time I see a new Great Scott video in my subscription box it puts a smile on my face. Thank you.
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...
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!
6:26 I love your curve fitting! :D
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.
I thought you were going to build an MPPT charge controller
Maybe in the future
GreatScott! please do it
yes do it
plz
+
throw away account yes. it's pretty simple. just need a current sensor, microcontroller and a buck converter
Your diagrams are so perfect. Are you sure you don't just print them out and then LOOK like you're drawing them? xD
Thank you for explaining the MPP value and MPPT, I think with your explanation I now understand what the MPPT charge controller is doing!!
Scott. Your brilliance, like the led, is illuminating !
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 👍🏻
When you have no knowledge about electonics, but you still enjoy a well made video.
understood everything this time . the content was nicely explained and easy to understand ....from INDIA
I have an oral exam in semiconductor electronics tomorow so this came in very handy! thnx Scott, great video :)
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!
Mom : What are you listening ?
Me : UA-cam classes
Mom : Who is your teacher
Me : GreatScott.....😜😜😜
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.
Very nice Scott
Thanks
Your posts are like knowledge pills and I get answers of lots of my questions in those. I really want know more about the solar cells please make more videos of them.
Great Scott
Thank you Mr Great Scott. Your videos have always been informative, but I prefer your Electronic Basics and your "make" videos.
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
Your hand writing is fantastic!
please make a diy mppt charge controller...
On my to do list
Can you please also explain how can we do simple charge controller for 6v panels! VPCC (voltage proporsional charge controller IC) modules are way expensive than the panel itself...
thank you for great videos!!!
GreatScott! Great because you bought a fake!
Julian illet made one, it was years ago but he did it
how long is your to do list? :)
GreatScott Is a beast of an engineer .
I get excited whenever Scott says "Let's find out!" in that pronounced German accent
German accent? I think he's Asian.
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'd love to see an updated version of this video. Now there's the CN3791 Solar Chargers for a few bucks and It'd be cool to see if you can innovate something better.
Thanks Scott. I learned more in one video then I have in multiple others.
It would be indeed a great one if you could make a diy mppt charge controller for solar panels. GREAT Great scott
Vikram Sha Agreed by everyone!!!
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.
I was hoping that you did a vlog about solar. thanks
maybe a diy lipo solar charger vlog? :-)
Very informative. It's great to learn those little technical details that make everything sense
Nice. I just studied about photo-voltaic cell technology last semester in college.
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
You draw ridiculously well. :)
I once ordered a super cheap one. Don't repeat my mistake i all I'm going to say
Nice video as always man
Always educational from where I'm sitting. Thanks!
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.
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.
I imagine you could do quite a few videos on solar power management and some fun applications
Fingers crossed!!!
Thanks for the upload, Cheers
"dont forget to like share and subscribe, stay! creative and i will see you next time" JUST LOVE THESE LINES AND THIS CHANNEL THANKS FOR UPLOADING VIDEO BASED ON SOLAR PANELS :)
No problem
HEY GREAT SCOTT CAN U PLZ TELL ME HOW CAN I BUILD MY OWN VOLTAGE BOOSTER? YOU KNOW I'M A BIG FAN OF YOURS I SHOW YOUR VIDEOS TO MY FRIENDS THNX FOR REPLYING ME :) LUV U KEEP UPLOADING THESE VIDEOS
XD
Time for a Q&A guys like so he can see.
Excellent how to video! Thanks a lot. Easy to follow and understand.
Thanks for the detailed reference, circuit analysis and your precious time sir...
It would be very nice to see a DIY MPPT charge controller!
Hopping for it :)
That was the best short video I found on the topic. Tyvm
Yeah, it's here! So excited for this one.
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
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. :)
Episode is very well done. I also enjoyed how you presented information via excel. Cheers
Thanks mate
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 ;)
ur circuit diagrams are awesome...
Please make a whole project with these :)
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!
always a pleasure Scott. outstandingly explained.
great video ! please upload another like this
good teoretical presentation
#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
Are you finished?
Wft, I'm from Poland too and had a very similar idea for University project
Hey! I would like to see a good Class AB amplifier on this channel :D Keep the good work!
great scott .. all the way up u need more subs
You can get very nice BQ24650 based MPPT chargers up to 8A charging current for less than 10 bucks on Ebay. Maybe not beefy enough for some applications, but with one of those 100W panels they're fine.
you definitely know what you are talking about!
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 :)
mind blown yet again, this channel is awesome!
You are literally a genius!!!
Your vids are always amazing. I click on them not knowing its you and happy every time. Keep it up!
3:42 He showed the direction of flow of electrons and labelled it as conventional current flow
wow never been on a gs! vid this early
GREAT Scott as usual. =)
excellent explanation
Awesome! I doubt it was due to my comment but I have been asking for this one. Perfect timing! :D
Please build your own MPPT! i would love that!
Great video I wasn't aware of difrence between mpp and nominal power. Could you present video about types of solar cells?
Great Scott => please disassemble a MPPT controller and explain us the science behind their operation.
I have opened few controllers (both working & dead) but unable to analyse the working, since i don't have oscilloscope & other sophisticated test equipment's.
Thanks, nice and clear, I like the pen diagrams
this guy is a German genius
Great info very helpful. Thanks
great video man. thanks for all the wonderful information!
great scott!! i like your work and i want you to please make a video on rfid with arduino
You should make tutorial on Night Panels.
Why?
Because you are genius.
very well explained .
Great video as always!
Great, Scott!
Once again, very informative video. Keep it up
Solar panels absolutely need to be encapsulated in a specialized resin to keep humidity from destroying them. I have no idea if the resin affects the performance but it is necessary. DIYers can do iot.
Well done
So,
Will you make Portable Laptop (or battery) Charger?
Maybe in the future
There ARE some power banks that can power a laptop for several hours.However, you will find it not worth the time since it is too heavy. I'm going to replace my laptop(a 2.5 kg one) with a much lighter tablet since I can no longer bear the weight of all these equipment.
That was good. Won a subscriber.
7:07 nice Orange juice man.
