Correction on our toll-free number: 877-878-4060
We discuss the difference between solar panels that have 60 cells, or squares, and 72 cells. The 60 cell solar panels were originally designed for grid tie solar systems, but thanks to MPPT solar charge controllers are now also used in off-grid solar systems. The 72 cell solar panels are also known as 24V panels, as they were designed to charge a 24V battery bank. With new codes and technology, they are now also being used in large grid tie solar systems.

If I ever become President, you're going to be a major advisor! David
You are the best and I mean it. Keeping things simple and to the point. Before I can think of next question, you have already though of it and start explaining. Keep it up Thanks
Excellent basic language to explain. Perfect! Thank you!
I watch all your videos in the hope your knowledge will rub off. I'm a complete newbie. Usually you lose me after the first few minutes, but I must be learning because I got almost half way before you lost me. lol Keep them coming. I am learning. :)
Thanks so much. Let us know if you have any questions you want us to address. I'm always looking for ideas for videos and blogs.
Angela Fiebelkorn welcome dear Angela good knowlege
I will have to go over this a few times, but i like she gives a pretty good general overview of requirements and outputs intelligently without hype.
Ok. This is like my 6th viewing. I am studying for NAPCEP and you cover about 1/3 of the test in very practical terms. Your experience shows. I recommended it to my classmates. We all use your website and you are a great teacher.
Thank you again. I now plan on watching all your videos, and getting much more *great* information about ALL things solar. Like and subscribed. ***
Nice job explaining this process for a change. Thank you
I find your videos very informative, we are currently using a small 12 volt system with a pwm controller (for the last 11 years), I'm adding 2 more separate systems and have been "discussing" with my hubby the benefits of using a MPPT controller vs buying a cheaper PWM controller, we were gifted two 320 watt solar panels (originally grid tied), this video finally convinced hubby that the MPPT controller will work better for us with our 12 volt batteries. Didn't realize you were also a marriage counselor, LOL 😜
Hubby.......................
@@CarlosAlberto-ii1li yes, and an awesome one too! ❤️
Thank you a bunch for putting out these valuable precious infos,God bless you ,
Thank you that was a great video. I made my own system 3Kwatt 24 volt battery 5 years ago and all your data and advise was accurate and very helpful.
One thing you should mention is that with a grid tied system with no Batteries you do not have any power if the grid dies. People think, oh I have solar panel so if the goes out I'll be fine, WRONG if the grid goes out it disconnects you from the inverter for safety for the utility workers repairing the grid. Also the grid power "Guides" your inverter to the correct voltage and frequency
john Randall in California
We have done several videos that talk about the fact that grid-tied solar goes out when the grid goes done, as well as how to add battery backup to an existing grid tied solar system. Here's one example. th-cam.com/video/6WRLdZQeK9c/w-d-xo.html
Great explanation and presentation. Thanks Amy
Well that was a good explaination...I have been trying to learn a lot of things about solar panels from various sources and this indeed was very useful.Thanx a lot for sharing this piece of information.
What a smart and beautiful woman. Looks like Massachusetts Irish. She is so talented at her presentation it makes you want to buy solar panels from her !
Thank you. And you are half right, Irish/Canadian French.
Wow.. thanks to this lady.. I know now what should I get next... great job.. thank you..
Thank you Solar Queen!!!
You can see why there is very few dislikes, there is no crappy annoying music and she clearly knows her stuff.
Excellent description of the different types of panels
I like the real world numbers on your channel,most "green" energy people do their magic with numbers to make their product look better.This is the reality users get.
greetings from Scotland. Lov the vids. Very informative and clear.
Agreed
A 60 cell PV panel can actually charge more efficiently a 24V nominal battery than a 72 cell PV panel.
A 60 cell PV panel will have a max power point voltage output of 27 to 32V based mostly on temperature.
Even in extreme condition when panel is very hot and max power point voltage is say 27V the panel will still be able to charge a battery that is at 28V or even 28.8V at slightly reduced current and max power point power but since panel is that hot it means that you have excess energy anyway so slight reduce max power point charging in those extreme conditions is irrelevant.
If cost of 72 cell panels and 60 cell panels will have been the same per watt you can buy 6x 60 cell panels instead of just 5x 72 cell panels for same amount of money and the 6x 60cell panels will sure put out more more energy in all weather conditions.
So not only 60 cell panels work with 24V nominal battery but they work better than the 72 cell panels.
Also using 60 cell panels on 24V battery can be done with non MPPT controller since you already use the panels at max power point and in that way you save even more money. (60 cell panels will probably not work at all with most MPPT charge controllers and 24V battery since there is no space for optimization).
So unless your panels will be very far from the battery and you need to deal with large voltage drops on the PV cables 60 cells are a much better option.
I of course use 60 cell PV panels with 24V battery for many years and they perform excellent in both hot and cold weather.
Using MPPT in offgrid type applications is useless and if you want to know way search for may video named "Is the MPPT obsolete in offgrid solar?"
ElectroDacus builds a nice PWM controller for charging LFP batteries for up to 3KW of solar.
However several problems arise with his comments above regarding costs, using PWM v. MPPT and Panel types.
Electrodacus's comments are valid ONLY for smaller solar systems, those built and wired very close to panels, charge controllers and the batteries. Not everyone will do that. When you get above 3KW of solar his numbers don't work. For example, having MPPT controllers connected via high voltage (low cost) wiring and solar array strings many metres apart yields significant DC cable cost reductions which are not available when using PWM charge controllers in the same situation. ie many metres far away in a field.
1) Efficiency is not only about matching the output voltage of 60 cell panels to meet the limitations imposed by using PWM controllers. An MPPT charge controller allows the use of either 60 or 72 cell panels and when there is not much sun about you need every watt of power you get into your batteries.
2) Loading down a solar panel and operating it outside the manufacturers recommended maximum power point profile (whether 60 cell or 72 cell or otherwise) is just plin dumb. You are paying for capability in the panel you can never use because a PWM charge controller is too "dumb" to manage the panel properly. You don't see PWM controllers used in professionally designed systems (3KW and above) for very good technical reasons.
That said, I would love to see Electrodacus design and build an MPPT version of his LFP PWM controllers.
The only reason he said he did not I believe was the electronics would then have become more expensive and it would have taken him longer to design and build.
With modern Off Grid solar systems (going north of 3KW of installed solar panels) just for an average house, using several high voltage panel strings coupled with an efficent DC wiring design, multiple MPPT controllers and new LFP batteries... That is the way professionals do it. PWM controllers are not used by professionals for good reasons.
So,both are right; that is what i thought; i have a 1 kw setup (at full sun...) at 24 volts (60 cells each panel) and the batteries charge well, via cheap PWMs, harnessing the panels` full Amps .
brigth and beautiful explanation...now i know how tosize my project solar system...god bless mam..thanks a lot...
Exactly the information I needed! Thank you
That was great. Thank you.
You make sense to a point lol. It's always helpful! I get more and more rewatching these things after I watch your other videos haha
I love the ALT E videos. They are very informative. I have a lot of 72 cell panels. Still waiting to use some of them.
Awesome.....simply awesome
There is a good diy green energy guide on EzBatteryKit ( . ) com that can help you save huge on batteries
Rich Machten i see your comment in almost every solar electric related video i watch
With modern Boost/Buck converters, any battery arrangement can be charged by any panel, although closer voltages will give greater efficiency. So, I charge a 48v LiFePO4 pack to 58 volts from 5 300w panels in parallel with a VOC of 44v each. On cloudy days they run at about 36-38v and 43v on sunny days. Excess power is shunted to a water heater through a DC relay switched from the thermostat.
Great video. I've been playing with solar for a while and you finally cleared up MPPT for me :-)
You just blew my mind! So well explained!
Thank you so much for these.... its been very helpful
very well organized information. thank you
This is an excellent technical explanation. Good work.
Such a great job explaining! :)
Hi,using say a mppt battery controller is only good to show current going into the battery.
The voltage will keep going towards 15volts on a 12 volt battery.This is because the word
controller is for the current being drawn by a load,not for what is going in.The only product to
purchase is a solar battery charger.The series string of panels does give you higher voltage
but average current. Parallel string panels give same voltage but higher current.This is
important when the environment around a house roof has many trees which cause
shading, which kills each cells output.Thanks
Love your hair!
Nourished by solar panels.
Thanks for clarifying/demystifying terms like MPPT and how the considerations of grid-tied vs. standalone systems impact the overall system design. Now I realize why many solar vendors lost interest when I insisted that I was only looking for a standalone backup system! I wish all success to your business.
Good job
Thank you for the information I learned alot!
Great video with lots of useful information
I have been off-grid for about three years. Minor upgrades have taken place over that period of time but still using the 16 year old panel from my original experimental system when I lived in the city.
I am looking for a serious upgrade, but still intend on sticking with the 12V battery voltage, because everything I have runs on 12V and it is too costly to replace it all with higher voltage things. With that said, I do have a 30 Amp MPPT controller, as well as the original PWM controller that is actually part of the back-up charging system now.
The question now id whether I should add one or two more panels, series or parallel, to the existing 125 Watt panel...
After watching some of the videos, it looks like I'll be buying a couple of panels, wiring them in series and feeding the MPPT unit while adding the existing panel to the backup system.
Then there is the issue of the wind turbines... They produce a much higher voltage than the solar panels and that is a whole different animal in matching them up.
Your expanded system would need multiple controllers managing the system. The 125W panel should stay on its own controller, and the new larger panels should have their own MPPT charge controller. If shading is not an issue, then they should be wired in series for higher voltage and lower current, thus lower voltage drop. Then the MPPT controller will drop the voltage to the correct charging voltage for the 12V battery bank. When sizing the controller, take the total watts it is controlling divided by 12V for the amps output needed. For example, if you add two 300W panels, you need 600W / 12V = at least a 50A charge controller. With the wind controller, if it is charging at a higher voltage, you may need to put in a diode to prevent backfeeding to a lower voltage charger.
@@AltEStore That is pretty much what I thought. I don't plan on more than 300 Watts. The batteries are golf cart batteries, (Trojan t-105). Currently, the 125 Watt panel charges them up fine in the summer but when the shorter days of winter set in, I have to run supplemental charging (generator tied in that I use for cooking).
Four 100 Watt 12 Volt panels would be ideal, wired for 24 Volts, 400 Watts is still close enough for my purposes, (14 Amps) I'll never see that here in reality, feeding the 30 Amp MPPT controller. The 125 Watt panel can go back on the PWM controller in parallel with the auxiliary charger. (on the inputs)
I am still looking for something that can handle the voltages of the wind turbines, which get higher than 130V in high winds. I knock it down right now with a 500 Watt halogen lamp in series to limit the current but in lighter winds, it absorbs most of the power that could also go into the batteries.
Great video Amy-Thanks a bunch.
Great video for Solar 101. Btw I love your big hair!
Solar panels must help hair grow! I want some
Thank you , yes it is very helpful
I REALLY LOVE YOUR VIDEOS.
THANKS
Excellent stuff here.
I like your explanations
It's a great explanation, very useful. Thx u.
A 60 cell panel will charge a 24v battery bank just fine using a pwm controller. Under load or when the batteries are low the voltage drops and the panels hit their maximum power point. You'll only get 5-6 amps on an 8 amp panel at 28.8V, but that's when the battery is almost full. Under load or when the batteries are discharged, 60 cell panels hit there power point at 26V and 7.5-8 amps. I'm not just guessing about this as I have been running a 60 cell panel with 24v battery for 2 years. Sure the panel amperage drops as you approach full charge, but so does the batteries ability to absorb power as it approaches full charge. You do get a little less in the summer heat but you can get 2 x 60 cell and pwm controller (14 amps) for the price of a 1 x 72 cell panel and an mppt controller (10 amps).
Exactly, that is the setup i have,works well.
fantastic explanation for 12volt &24volt pannels difference . thanks a lot . keep it up good job . super .
Love your teaching
So Much Great Info! Thank You
very informative thanks
Another good video.

Thanks.
Great info. Thank you.
Really nice educative videos here!
Goodness gracious me, would I like to go on a date with you. :/ This is the fifth wonderfully informative video I have seen of yours. Thank you and love from Australia.
Can be connected 320 watt 12 volt 3 pannel & 375 watt 24 volt 2 pannel in series
When the panel is tilted off square with the sun, its AREA is LESS; projected area,that is;
if you tilt it off 90º, having the sun hit on its edge, the area becomes ZERO,of course.
very good information
ohh god..... THis Woman have Amazing Hair. Wish my mom has this thick hair( and I also had it on my head)
yep...the hair's hot
Amy have you done a tutorial on the pro's and cons of series vs parallel solar panel configurations?
To me it is best to maximize solar panel voltage, so it will exceed battery bank voltage even on cloudy days, and charge the batteries...So the solar panels will have useful output for more hours per day.
I'm sure there are disadvantages, just don't know how to quantify them

Norrbob thank you. That video is for mismatched solar panels. I want to optimize output for matched solar panels
Good job. Thanks

RIP SOLAR QUEEN
I'm sizing a mobile off grid system for a van and plan to use 2x 60 cell panels in series via an MPPT charge controller, charging two 12v deep cycle batteries wired in parallel. If I understood you this should work perfectly?
Yes. Just make sure the charge controller can handle at least 80Voc input and remember the amps the charge controlelr is rated for is the output, not the input. So if you have two 250W panels, 2x250W = 500W / 12V battery = 41A output. So the charge controller has to handle at least 40A.
altE Thank you, didn't know it related to output amps, very helpful. Have subbed 👍🏼
Well done.
If most home owners are going to use roof space which garner the most light then most projects will be on the size of roof area and not on battery storage or output required. The bigger the sun facing roof space, the bigger the potential output.
Good point. We cover that in some of our other videos. Sometimes the solar array to make all of your power just doesn't fit on your roof, or in your budget. That's the beauty of grid tie solar, make what you can, and buy the rest of the power from the grid, same as usual.
Hi it make no diver-ens if you use panels for charging battery's or for a grid inverter for delivering energy on the local net. How more cells a panel have how higher the voltage how more energy by courtly weather.
+altE It's not just roof space as the limiting factor but what you hope to consume. Selling to the grid is nice but all but eliminating your power bill to a nominal bill is ideal

Hi, thanks for the great information, you said at 4:50 that it is not possible to charge a 24v battery with only one 60 cells panel, if the Voc is about 38V and Vmp is about 31V (so still over the needed 28.8V to charge battery) , what is the problem then?
While you technically can charge a 24V battery with a 20V panel, it is not a good option. When it gets hot, the voltage of the solar panel drops, so in the summer or any hot weather, you may not have a high enough voltage to completely charge the battery. That can cause the battery to be in a partial state of charge for months, which is not healthy for most lead acid batteries. Keep in mind a 12V panel has 36 cells, and a Voc of around 22V. So a panel to charge a battery voltage twice as high should have twice the cells and twice the voltage, thus the 24V 72 cell panels. You can see a demo of it here, th-cam.com/video/4hU6FUiFI2I/w-d-xo.html

Hi altE store
I have watch so many videos of you and get so much knowledge about solar power system. In February 2020 i am installing solar system in my home in Pakistan faisalabad. I have bought A class solar panels and inverter with net metering which will be use without batteries right now. Later on i will use batteries. Now the point is i am worried about the solar panels connection to inverter because in my locality there is no expert electrician. So can you help me out in connections.
Hay Amy thanks again for being so brilliant and giving us a clearer idea. In the picture towards the end of the video where you showed us the 60 & 72 cell panels I also noticed a much bigger one in the background. How many cells were those?
How about the 70 volt solar panels...mppt should be able to have a field day with that!?
MPPT will manage that beautifully.
Wonder why it worked for me as far as 24 V charging. I had one 170 watt 37 volt anel with a cheap eBay controller and it charge my 24 volt battery bank all Last summer.
i like your channel. subscribed!
So to keep the heat down on your panels, don't Mount them on the roof of you're home. Besides you don't want to be walking on your roof, that protects your whole house stay off of it.
October 17, 2019 Solar, wind and biofuels could help reduce the risk of explosions and fires, like Crockett, California, as seen on ABC7 official website videos on You Tube. Ideally, this altE Store videoshould be included in a free, online, kindergarten through graduate level 'home school.' Teens could quickly prepare and pass the GED exam in order to start college courses early, online for free. Most college is free for any teen, including test book fees. The teachers should be paid as much as possible to tutor, as needed, from any location, using Skype. They should try to get funding from the new group called 'Resource Generation' interviewed in the You Tube magazine called 'Town and Country.' Try to Skype daily for five minute updates, with the co founder, the son of the co founder of Qualcomm in San Diego, CA. This could really help all students with learning differences like dyslexia, ADD, autism spectrum, etc. And this might help prevent them from dropping out and getting into major trouble. They should be allowed (and rewarded by vegan food companies) to read out loud, cover to cover, on You Tube. Ideally, all authors and publishers should encourage this instead of punish this with threats of 'no more than four pages are to be read out loud in any public setting.' This is really crushing to millions of students who need to improve their reading, by reading (practicing, 'practice makes perfect', (or listening) out loud, cover to cover. Please read and use the book, 'The One World School House' by the MIT graduate, Salman Khan. This could help the thousands of students during the Chicago teacher strike (and similar, almost every year, in a different location). Thank you for reading this carefully, discussing this with your friends, and if you are talented or wealthy, to help make the above happen. G'Day
At 1:50, she said, we need 4 12V panels or 2 24V panels to output 72V. I think that will be 6 12V panels or 3 24V panels maybe.
A 12V panel doesn't output 12V, it's closer to 18V. It is only called a 12V panel because it is the right size to charge a 12V battery. So if you have four solar panels outputting 18V, you will get the needed 72V to charge a 48V battery bank. Likewise with 24V panels, they output closer to 36V. Two in series can charge a 48V battery bank.
Thank you. Its clear now. Also can you tell me, if I have a 24V solar panel and 14V battery and 20V solar charge controller, will the controller work. I know you said, that the nominal voltages should match, but what happens if I don't.
Sourya Dutta If the solar panel doesn't match the battery, you need an MPPT charge controller that will do the conversion. Otherwise, you will either lose most of the power from the charge controller, or damage the charge controller if the solar voltage is too high. Look for some of the videos we did on charging a 12V battery with a 24V panel.
good video thanks
Great vid Amy
Or should I say great vid muffin top
No, you shouldn't
@@AltEStore Bwaaaahahahaha
very nice
mam can u tell me about 12 v battry and how to recmend solar pannel and which watts and which sirres
When I first heard about salt batteries, it was stated that they had to be kept at 700 degrees, which eliminated home use. In layman's terms, how are you doing this at ambient temperature.
Totally different technology. That is molten salt, this is salt water.
being a newbie on the solar panel, i chose the mono. could i connect the mono with poly panel in the future? i will stay with all mono just to be consistent to the voltage output. i have purchased a 100W and a 200 Watt solar panel, should i connect 100 W to the 200 W downstream? what would happen if i connect the 200 W to 100 W downstream? would it cause the wire heating up? thanks for your video, learned a lot but still many questions in the future. i will use the solar for my mini camper. any suggestion on setting up the two panels on top the camper or keep them on the ground level for better sun exposer?
i honestly think batteries are a waste of money unless you get 6v, or 2, cells batteries which are really expensive, my next setup will use mainly grid tie inverters
It is very rare for you to save money with a battery based solar system. If your main goal is to save money, and you already are on the grid, then you should stay on the grid with grid tied. However, if you are at a location where the grid is not available, or will cost a fortune to install, then batteries may be the best option.
Nice and useful videos sir
I have a question
If I gonna design a solar street light with 27 hours backup if the Load is 65watt and the Sun hours are 7h
Then:
1:what battery size do I need
2:what penal size
3:what inverter size
4:if I use two penal(2*150) do I need solar combiner
.
.
.
.
To figure that out, we need to know how many hours the light will be on. Let's guess 10 hours, and do the math. I also suggest you get a DC light so you do not need an inverter.
Solar: 65W x 10 hours = 650Wh a day. 650Wh / 7 sun hours (are you sure about that number, very few places have that much?)/.65 system losses = 143 watts of solar needed minimum. Let's round up to 150W.
Batteries: 650Wh x 1.125 days (27 hours) / 30% depth of discharge) / 12V = 203Ah 12V battery. 200Ah is close enough.
If you do use two panels in parallel, you can use a pair of couplers to combine them. See this video th-cam.com/video/9xsf_l_mCEk/w-d-xo.html
thanx
I have been watching all your videos to gain more knowledge about solar panel. I have a simple question. Let's suppose I would like to buy 30W solar panel, does it matter what solar cell series it is? since 30w solar panel is smaller power than all are available out there.
A 30W solar panel would most likely be a 36 cell 12V panel.
How to wire lead acid battery balancing system
How more cells a panel have the higher the voltage how more energy by courtly weather.
I use solar panels for charging my battery's.
I have 6 panels from 96 cells that is 48 volt. I have a MPPT charge controller and charge a big 24volt 675Amp battery bank
i have 12 Trojan T105 battery's. 3 battery banks of four Trojan T105 batteries.
That goes particularly well.
The cells are wired in series. Voltage of voltage sources adds up directly, when wired in series. Each cell is generally 0.5 Volts operating voltage, so a 60 cell module is roughly 30 volts at its MPPT operating point, and its 72-cell counterpart will have roughly 36 volts at its MPPT operating point.
Modern MPPT controller can handle 150 to 300 volt DC. I have sins one week a new MPPT charge controller Fangpusun 150/60TR alias VICTRON that can handle 150v / 1750w panel power.
Now are al my panels parallel connected within a month i will chance this to connecting all the panels in series.
Now give my panels 57.5 volt that become the double 115v DC.
More efficiency and energy by cloudy wether. In a country as the Netherlands with a lot of clouds is this very important.
I'll keep you up to date.
I purchased 400 watt Trina panels sometime ago and just realized that they had TS4 connectors. Are these interchangeable with the more popular MC 4 connector? I have to purchase branch connectors and want to buy the right product
Great video. Took your advice on multiple parallel strings (batteries). I have three strings of four 6v Trojan L16 batteries (12 batteries total). I bought two Blue Seas Systems 250A busbars....going to wire them direct and keep the parallel cables in there too. Sound correct? That way it should balance everything out.
+Chris DIYer Anything you can do to keep the connections to the battery strings the same, thus provide even charging and discharging, is a good thing.
Thanks.
A few questions:
1. Can three 60 cell panels be wired in series (60v total) going to a MPPT controller going to a 24v battery bank?
2. If so, then what would be the upper limit of panel voltage going to the MPPT?
3. Can one MPPT accept parallel panel inputs of different voltages, e.g., one string coming in at 60v and another at 40v?
Thanks.
Answers 1 and 2 depend on the charge controller. Most MPPT charge controllers have a Voc plus temperature compensation of 150V. Those can take three 60 cell panels in series, even in the coldest environments, you'd be under 150V (38Voc x 3 x 1.25 temperature compensation = 142V). If you want to wire three 72 cell panels in series, you'd need a charge controller that can handle at least 165V, like the Midnite Classic 200 or the Magnum PT100.
#3 I am working on releasing a series of demos showing exactly that, they should be out over the next 2 weeks. Short answer, if wiring different voltages, but same amps, wire in series (if using MPPT that can handle the voltage). If same voltage and different amps, wire in parallel. If both volts and amps are different, it may not be worth the effort.
lol....no
i mean,it will work,but...not well at all..
3 panels of 60 cells give you 28x3 volts, or 82 volts !!! Danger!!! Danger!! 82 volts *DC* is NO kidding matter !!!! SPARKS will fly!!!
Any MPPT will ONLY reduce panel VOLTS
It CANNOT raise the amps of the panel, so, no point in using it here ( i mean, yes,but only a negative point..)
So, do not feed 82 volts to the MPPT,if it will only output 28 volts to the 24 V batteries,like you said
Instead,wire them panels in PARALLEL( around 22 Amps,MAX!!) and you can use a cheap PWM charge controller;
That is exactly the setup i have,works well.
Good. However, can the solar panel with micro inverter be operated in the night?
I'm not sure I understand your question. Will a microinverter work at night? No, it needs the sun. Newer microinverters can be used with a battery system allowing you to use the energy made at night. www.altestore.com/store/deep-cycle-batteries/lithium-batteries/enphase-energy-ensemble-energy-storage-system-p41457/#ENPENCHARGE10
Where were you before I put up the solar panels?
Here, waiting for you to find us ;)
Thank you, very informative. I wanted to ask, with the new solar transparency cells, are they the same voltage s as solar panels? Definitely appreciate feedback please

Sorry, we haven't seen the specs for the transparent cells, so don't really know. It's important to remember that a lot of the cool new technologies you read about are either still in development, or so inefficient it doesn't make financial sense yet. But work goes on, they'll get there.
