Electronic Basics #29: Solar Panel & Charge Controller

[@blubbspinat9363]

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?

[@greatscottlab]

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.

[@alexandruadrian3218]

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 ! ✌️

[@montoyo]

What? They named their company MPPT? Is this even legal?

[@VictorGarciaR]

Welcome to china

[@ahmedmani1051]

you can actually make a mppt charge controller using arduino look this up at instructables

[@Watchyn_Yarwood]

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.

[@greatscottlab]

I like it :-)

[@N0Xa880iUL]

William Garrett same here :)

[@rahulbalakrishnan7819]

William Garrett Same here. Also, his videos are easy to follow and much more interesting than "view bait DIY videos".

[@dongochenour]

they are the best!

This panel can put out close to 100 watts kzbin.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.

[@krystofzajicek]

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

[@programer0713]

R.I.P Solar panel

[@pzsoldi]

He RIPped through that solar panel.

[@CAHSR2020]

Stay destructive?

[@Mentorcase]

That's called creating a mess.

[@romanemul1]

nedelas nahodou v AUO site Brno ?

[@wanjockey]

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

[@douglasheld]

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

[@alairsilvajunior7814]

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.

[@davidl8239]

Best explanation for the concept of MPPT

[@tasmedic]

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

[@kurtrozario1]

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 KZbin, 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.

[@Jajaho2]

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

[@nicktohzyu]

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

[@therealcherti]

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.

[@zerodegrekelvin2]

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

[@danielmehdi5272]

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...

[@toddanonymous5295]

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

[@dzejaar1]

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 👍🏻

[@ABHILASH6409]

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

[@johnpossum556]

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!

[@Eytaris]

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!

[@DanHaiduc]

6:26 I love your curve fitting! :D

[@demolishedman50]

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

[@TUUBproductions]

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

[@finophile]

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

[@johnarry-jg4hz]

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

[@Iboo30]

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)

[@flincocowalski149]

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

[@reecedevine1681]

Your hand writing is fantastic!

[@AnubhabKundu]

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.

[@matthewfranklin8427]

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

[@964tractorboy]

Always educational from where I'm sitting. Thanks!

[@mostrush4849]

Very nice Scott

[@greatscottlab]

Thanks

[@mostrush4849]

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.

[@12gabriel3]

Great Scott

[@baatour]

GreatScott Is a beast of an engineer .

[@maheshbhat8714]

I thought you were going to build an MPPT charge controller

[@greatscottlab]

Maybe in the future

[@francescosoppera3670]

GreatScott! please do it

[@Simon-ex4mu]

yes do it plz

[@wobblysauce]

+

[@maheshbhat8714]

throw away account yes. it's pretty simple. just need a current sensor, microcontroller and a buck converter

[@Taran72]

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. :)

[@Jono6671]

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

[@remowo_]

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

[@davebutler3905]

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.

[@stevenjohn7770]

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.

[@markplain2555]

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.

[@MarcusChan]

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

[@DavidJJJ]

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

[@robertoaguiar6230]

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

[@MegaWayneD]

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

[@ranger175a2w]

always a pleasure Scott. outstandingly explained.

[@bharadwajroyal9507]

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

[@4thgradedropout980]

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

[@greatscottlab]

Thanks mate

[@Mr.Donahue]

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

[@frankobacic8396]

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

[@kayvendelatado8]

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

[@samynathanpec]

ur circuit diagrams are awesome...

[@zaneyoumans2923]

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

[@947h2]

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

[@vikramsha7554]

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

[@fieldsofomagh]

Vikram Sha Agreed by everyone!!!

[@N0Xa880iUL]

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 :)

[@AndyShell]

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

[@wntu4]

You draw ridiculously well. :)

[@SepticMonkey42]

mind blown yet again, this channel is awesome!

[@zigamahne4636]

good teoretical presentation

[@genuino-qo5yq]

please make a diy mppt charge controller...

[@greatscottlab]

On my to do list

[@nicolaedinu83]

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!!!

[@ELECTROHAXZ]

GreatScott! Great because you bought a fake!

[@nightshadelenar]

Julian illet made one, it was years ago but he did it

[@RCP-1136]

how long is your to do list? :)

[@caay0rasta]

great video ! please upload another like this

[@stephanmetph]

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

[@ryccoh]

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

[@paulortiz5047]

German accent? I think he's Asian.

[@ciarfah]

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

[@bobbarker2814]

You are literally a genius!!!

[@lejink]

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

[@Ravewayvideos]

GREAT Scott as usual. =)

[@apurvsharma1261]

"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 :)

[@greatscottlab]

No problem

[@apurvsharma1261]

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

[@apurvsharma1261]

XD

[@HarukiToreda]

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.

[@haleywojciechowski3661]

you definitely know what you are talking about!

[@robgandy4550]

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!

[@netpackonlinesolutions3254]

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 ;)

[@TelmoMonteiro]

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

[@anismahmud3636]

excellent explanation

[@HolgerBarske]

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.

[@marcinkanko7440]

#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

[@thoughtyness]

Are you finished?

[@LovelyAngel.]

Wft, I'm from Poland too and had a very similar idea for University project

[@LL4001]

Thanks, nice and clear, I like the pen diagrams

[@nader89]

very well explained .

[@LatinDanceVideos]

That was good. Won a subscriber.

[@arthurcascardo7202]

Once again, very informative video. Keep it up

[@victorchorques4893]

Great video as always!

[@barbasbandas6665]

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

[@PPSRHD]

Your videos are awsome!

[@AlexandrBarsukov]

This is methodical good!

[@kartaloktay]

Please make a whole project with these :)

[@VinothKumar-cr5cg]

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.

[@goodgoat6019]

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.

[@ahmetdemirhan9120]

thank you my brother
