[@BoHunter2010]

For a person new to these concepts, comparing a solar panel to a battery (AA for example) can really help to bridge the concepts. They can use a couple of batteries and see how connecting in parallel vs series changes the voltage. Then the solar panel discussions can make more sense. Thanks for the great intro video.

Cool i to follow you advertise

[@Bee_Jaye]

Ran across your profile researching solar energy on KZbin and want to pick your brain. I am renovating a 100 year old underground storm shelter and have made it to the point of installing a solar setup for a couple reasons. 1-power an exhaust fan and intake fan(12v PC fans inside 4” duct work that exit through ceiling) 24hrs day for air exchange and also for a few components that would only be used in a power outage (led light strip, interior circulating fan, maybe a small 12v heater.) I purchased a small kit from amazon see pic below. It’s a 20 watt panel, solar controller. I also purchased a 300 watt inverter, 20AH 12v battery. As my little projects normally do, they become way more than originally planned. Now I have a second 20AH 12v battery in route and Another solar panel, the 2nd one being 50 watt. I have built a removable panel that hangs on the wall that houses the batteries, solar controller, inverter, switches and a fuse block. After watching your video I know I want to wire the panels in parallel so they work independently even if one is in shade during a time frame in the day. I haven’t thought about the batteries and their wiring together yet. The solar controller is a 10amp pwm. I already want to upgrade this because I don’t think the low voltage disconnect is working as it should (battery drained to just under 8 volts during a two day cloudy period and fans were still running. I’m questioning my wiring for the switches. I connected the load from the controller +\- to the poles on the fuse block and wired off the accessory poles (see fuse block pic) to the components (pc fans, led light, etc. the switches do power the components but I don’t think this is right and may be drawing more energy from the battery. My battery is also wired to a master switch on the panel. Do you have any suggestions,thoughts, best practices knowing what I’m attempting? Knowing that I have two solar panels totaling 70 watts, 2 X 20 AH batteries, a 10amp controller, and my components, what replacement controller would you suggest or features to look for in one? I definitely want low voltage disconnect.

[@diylifegoals7728]

Ive been researching solar and trailer coversions into campers for the last year+ and i love the fact that so many of you guys inherently give credit whare it is due. ( referrence to another youtuber (Gone with the wynns)) you guys are great

[@aldo9564]

There is (another) well-received YT Expert on the subject of Solar. He has an incredible (Pedigree), but his vids get a little “rambling” which makes it Difficult (for ME) to follow. I especially appreciate yours for linear discussion points. You actually ‘conclude’, rather than leaving sub-topics .... Open-ended. Thanks !

[@curvs4me]

You can eliminate the whole series panels going down in shade with a bypass diode. This should always be included in a series wired install so failure of one panel does not stop the output. Generally running panels in series up to 300vdc sections in series is best bet for reasonable controllers. Heavy parallel amps creates a lot of heat and requires heavy duty controls

[@alafiatayoobamuyi1118]

Thanks for this contribution. Please how can one include the bypass diode to serve this purpose?

[@ThomasSmith-ug2gk]

I have my panels set in sets of 9 240 watt panels. Having do a lot of heavy electrical work. I took my panels and set them up then I took a large cardboard and covered a panel I lost the out put from that panel and nothing more. I also covered just a spot of one panel and I lost about half of that panels out put. I have contacted the builder and they said all of there panels made over the last 10 years have bypass diodes built into them to reduce the lose. Now what I have found is two of my sets of 9 panels are then tied together and then I would block off one panel in one group of 9 and it dropped at the combiner the output of doth sets as if they only have 8 panels working together.

[@monono954]

You should consider that The search for flexible panels had free shipping. When I went to buy panels, a 300 Watt framed panel was $120 which seems fantastic. But they ship exclusively through freight shipping; that ended up being $260 for shipping one 300 Watt panel. I ended up going for a flexible 300 Watt kit for $360 with free shipping.

[@billarroo1]

Nice explanation, eazy to understand, I started in this about 35 years ago, when I bought my first ARCO 40 watt solar panel (used) for $250.00 !! and an actual mechanical/electronic solar charge controller, that had contacts you could hear clicking PWM, wow has solar progressed !! Great Video, THANKS William Orange county, ca.

[@todddunn945]

Nice job except for two things. First, your comment about controller capacity is somewhat misleading. First, if you are going to wire your panels in series or series parallel you will want to use an MPPT controller NOT a PWM controller. In that case you need to look at the maximum solar array wattage that the MPPT controller can handle AND the maximum open circuit voltage that the controller can handle. For typical 12 volt panels the open circuit voltage is in the 21.5 volt range NOT the 17.5 volts you mention, which is the operating voltage. So when picking an MPPT controller for series or series parallel wired panels you need a controller that can handle your total system wattage and the total open system voltage for your array as wired. For example, four panels wired in series will have a maximum open circuit voltage of 4 times 21.5 or 86 volts, so you need a controller that can handle at least 86 volts (say a controller rated for 100 volts) Another consideration is that the amperage rating for MPPT controllers is typically the charging amps NOT the panel amps. For a series wired array the charging amps can be estimated as array wattage (say 600) divided by charging voltage (say 14). So for the 600 watt array 600/14 = 43 amps, so you would need a 50 amp rated MPPT controller to handle a 600 watt solar array. Second although your graph showed the dependence of wire size on amperage AND wire length you completely forgot to mention length in your discussion. Wire length is a critical parameter in choosing wire size. The longer the wire run the larger the wires need to be. I say this is critical because someone listening to your video might come away thinking that wires should be sized based on amps alone. That can lead to a very unsafe setup. I say unsafe, because under sizing the wires can cause a fire. Other than those two details a very nice video.

[@DuetJustusFam]

+Todd Dunn This is all great information Todd. Thank you! 😊 As I’m sure you know, there is only a certain amount of info that I can put into a video before I lose the attention of the viewer. All of this will be covered at some point in the future but this video was strictly focused on the solar panels of a solar power system. Thanks for watching and I’ll see you on the next one 👍🏼

[@kiowablue2862]

Gary Hornbuckle, you've got it reversed. Increased wire resistance will cause a VOLTAGE drop, NOT a current drop. Current is the same at all points in a series circuit. Ohm's Law says P = I*I*R. For example, if a wire carrying 8 Amps, has a total end-to-end resistance of 0.1 Ohms, the power dissipated in that wire will be 6.4 Watts. Decrease the resistance by making the wire larger, say to 0.05 Ohms, and that wire will dissipate 3.2 Watts. If it weren't a safety issue, then it wouldn't be an NEC violation to protect a branch circuit in a house comprised of AWG 12 wire with a 40 Amp breaker. AWG 12 wire is rated for 20 Amps max. The wire will eventually overheat and cause a fire long before the 40 Amp breaker trips.

[@shaynegadsden]

Its voltage drop that is the concern im going to be lazy with the figures but you will get the point Say you have 2000w solar system at 100v 20a and you have 10v drop over your cable well the charge controller will still see 20a but now only 90v so your useable power is 1800w it doesn't matter where on that circuit you test there will be 20a as for any danger well no if the cable is made for 20a it will be fine just wasteful, now i know what your saying about the cable affecting series resistance but it is such a negligible amount you never worry about it a 2mm or 12 gauge wire which is rated 20a is .5ohm per 100m or roughly 330feet which you would never do with a cable that size

[@shaynegadsden]

@@garylhorn the reason i used such a small cable and large distance is to show how small the resistance is but if you want to use your 3 feet of 0000 gauge well that is 0.000143 ohm so double that for positive and negative so if you were working out your ciruit resistance would you bother adding 0.000286 or just forget that bit

[@kiowablue2862]

A total run of 100 meters wouldn't be too difficult. Don't forget you have to count both the supply side and the return side of a wire pair. So a 50m run of 2 conductor wire would effectively be 100m. My house is 120 feet long from end to end. My load center is 28 feet from one end of my house. There's four runs from the load center to a room at the opposite end of the house aproximately 90 feet away. Adding another 3m for vertical travel, i.e. from the load center to the attic and the attic to the receptacles, the total one-way distance for each of the runs is ~100 feet. accounting for the pair, that's 200 feet of wire per run. So while a 100m run is not likely to be a common occurance, it's definitely not difficult to do.

[@gregorydugre891]

I have solar panels on my house. It is an 8K system with 29 panels. I went with microinverters on each panel. Microinverters convert the panels energy to 120 VAC at each panel and then send the low amperage current to the main panel. Each panel operates independently and shadding on one panel doesn't effect any of the others. I don,t have a battery back up system since I am using a grid tied system so your need may be different than mine. You might want to look into it. I plan on retiring in 4 years and hitting the road full time in a class A and solar is a must for me. I think you have done an exelant job explaining things. I have subscribed to your channel and have watched all of your videos. Thank you for sharing hopefully we will see you on the road in a few years. Greg & Grace

[@sup8pdct]

Depending on manufactuer, most panels from 60w and bigger have 1 or more bypass diodes that help with shading issues for series connected panels. If 1 bit is shaded, the diode conducts so rest of string continues production

[@boyerobertson351]

It is fantastic. I am not an electronic technician but with this video I am becoming a complete electronic technician. Thank you

[@richardowens9061]

Great video! You covered the basics quite well! I would only add that, when comparing poly and mono panels, the panel power ratings may be the same for full direct sun, but the poly panels perform better in less than ideal conditions, like partial cloudiness or a shallow angle to the sun. This difference can be significant over the long term. And, it can best be measured by looking at total daily solar production for both mono and poly panels added up for thirty days, then averaged by dividing the total production for 30 days by 30 to get the average production per day under identical but less than ideal conditions. Then, subtract the totals to get the difference. Spoiler: The poly panels win.

[@vet137]

Never read anyone mention this before? I am skeptical so I will do my own digging into that comment. If that is true then why are poly cheaper? Seems the companies would not want you to know that the "cheaper" ones are better? hmmmm

[@billc.4584]

Very cool. Thank you. I'm a fairly bright guy and just about 50 years ago I was taught all of this stuff in high school Physics of all places and promptly forgot most of it not having gone into the electrical field. Kinda' toying with the idea of solar and getting up to speed with what I'll need to know. By far, this clip was the best, clearest and concise summary of the hot points I have seen to date. Just fucking excellent.

[@anjosamehere7493]

FYI solar now a days used internal diode incase of shading, so shading one of the panel that is connected in series only affect the solar been shaded.

[@unimogdave]

Thanks for adding that comment, I just installed two panels in series and when one is shaded I was still getting full output from the other.

[@souhailshamaissem7564]

I just do g some research on solar panels and your video is by far the best I have seen so far. Keep up the good work mate. Well done.

[@MrMosquiton]

Thanks for the info. Btw you didn’t mention about the big difference between mono and poly. Mono are designed to be exposed perpendicularly to the sun rays, the crystals are oriented all in the same direction. Poly has multiple oriented crystals, so less efficient compared to mono at 90 degrees but more efficient in any other angles. I think polys are best in winter, northern regions and places where the sky is cloudy the most of the day. This is what i found reading over internet but if i’m wrong or i’m missing something as technology improvements, feel free to correct me (sorry for my broken eng)

[@DuetJustusFam]

Thanks Roger 😎

[@Brokendiode]

An excellent presentation, a well done video, I just wanted to point out a way around the loss when running panels in series and one getting shaded, The reason for the loss when shaded is the fact that an unlit cell is almost an open circuit therefore allowing the rest of the cells to reverse the polarity of the shaded cell or cells, however most of the newer high quality panels have blocking diodes across portions of the panel as they cannot put them across individual cells as the forward voltage drop of a standard silicone diode which is 0.6 to the threshold and as high as 0.9 at it's full rated current, is greater than the voltage produced by a single cell which is 0.5 nominal depending on cell temperature. The easiest way to get a series string of panels to operate just like the parallel panels do losing only 25% when one panel is shaded in a group of 4 as he is showing, is simply to place a shot-key bearer rectifier diode across each panel, as they only have a 0.3 volt forward voltage drop to the threshold and will be less than 0.5 volts at full rated current making it equivalent to the loss of a single cell.

[@healthyishgal733]

GREAT EXPLANATION! I finally learned the in depth info I was looking for!

[@seanjanson2144]

Great video, no question about it. Nevertheless, I'd like to point out a few things I noticed: 1/ Error @ 15:20 - diagram should show 35V instead of 24V (in parentessis). 2/ The shading issue is even more pronounced by the fact that the cells in panels are usually wired in series, i.e. even one shaded cell can knock off the full panel. 3/ MPPT controllers have different efficiency with different input voltage. Usually, the higher voltage (70V) is more efficient (then 17.5V), but it depends on the controller rating.. I wouldn't consider PWM controllers at all. This does not diminish the fact that your video is EXTREMELY detailed and thorough. Thank you.

[@Psi-Storm]

The shading isn't that bad in series as he claims. Solar panels come with 2 or more bypass diodes. If part of the panel is shaded, the cells get bypassed so they can't kill the whole string. Only the shaded panel is down. The voltage for the string drops and if it gets too low, the efficiency of the inverter suffers.

[@Dsonophorus]

nice video. I wanted to add that panels wired in series do not stop functioning if one of 4 panels is occluded. The voltage would drop by 1/4 and you can use the remaining voltage with an MPPT charger which operates a large variance in volts.

[@kennethschultz6465]

Yep so truh ITs becaus of bypass diodes in real panels If they buy substandard panels with out the BYPASS DIODE's/DIOD But this Guy is just parroting others flaws!! Mono is also way mor efisiant in cloudy weather Then poly!! The states numbers are fully sunshine on both panels Not a cloudy Day on mono Vs poly crystalin!!

[@CapnCody1622]

What’s the advantage of having more volts over amps or vice versa?

[@sebastiangeorge7714]

High voltage thin kabel, thick isolation, expensive charge controller. High amps the other way around.

[@vipulgarg1532]

Thanks a lot, this is genuine video i have ever seen among more than 50 videos on solar science, very calm and peaceful environment u gave, last part which is both model put together is confusing for me, its 11:50 pm here in india and watching this video make me feel great,once again thanks

[@emmyann8214]

Awesome info thanks very much

[@mannys4036]

That was the best and most comprehensive explanation of solar I've seen to date. You set the bar very high with this video. Awesome job sir!

[@wanderfulllife2407]

Thank you that was helpful.

[@keithsmith2192]

Fantastic, you made this so simple thank you

[@sharifsaghar3097]

It was really great n not confusing at all. May Allah the al migjty give u hidayah Love from Pakistan

[@KGRICK1]

@c dawkins show some respect, your comment proves you are the childish one here.

[@markb1699]

Very helpful. Very well explained. I am a newbie with 1 Wynn video, and 2 by Will Prowse. 1) Probably time for an update (the technology incrementally changes) 2) You refer to your other videos in a series and then "as you already know". LInks, links 3) As you instructed, series wiring has advantages, but shading is a problem. What is the current state of the art in using both Bypass and Blocking Diodes to eliminate this limitation?

[@toddramsay977]

This is a fantastic series. I know enough electrical and other things to be dangerous....LOL This series clarifies several things, but I will have a question or 2 later I am sure. Like how do I combine my solar input with other inputs to the battery such as converter with input from gen to be able to charge batteries quicker.?

[@claireclaire7504]

Todd Ramsay : Same here! Teletype techie in the Army many years ago and a long-time PC gamer. This is right up my alley!

[@rhueoflandorin]

glad you mentioned mixed-pairing (series & parallel grouping) because i was gonna be like: "you don't have to ONLY do one or the other...you can mix the two methods" but...you did mention it in the end

[@ReneMartinez-kl5lg]

Great information, thanks for sharing!

[@collectorsinfo]

Great tutorial that was made easy to understand & unlike many other videos, there was no waffling. Well done, appreciated. :)

[@davecurrier1167]

Silicone is something you put in a chalking gun. Silicon is a semiconductor found in solar panels. Just saying.

[@yousurf374]

true true....

[@Billy_Darley]

he also got supply and demand wrong.

[@KNIGHTJUMPS]

Yes, but some are failing to the possible ramifications of new laws on both chalking and caulking guns. I also worry that some terrorist will find a way to mix silicon with silicone and then add both of those to sillyputty and then well, I don't even have explain the rest. Now do I?🤣🤣🤣🤣🤣🤣🤣🤣

[@isaminecockers]

Err..I think it's caulking.

[@thesociallyresponsibleanar2882]

silicone is sand

[@cybercapri]

One thing you may have considered was to show side by side all 3 setups with the necessary wire and Controllers. You tend to over explain the easy stuff then under explain the stuff that matters. You might probably cut down the length of your videos but just cutting to the chase and reducing redundancy such as: Mono Poly Flexible Series, Parallel, Series+Parallel Series,Parallel, Series+Parallel Series,Parallel, Series+Parallel Watts, Volts, Amps, Wire, Controller Repeat for Poly & Flexible and of course efficiency and cost involved. I totally get that you put a ton of work into your videos; that is very clear as your content is A+++++ Your redundancy however, could use a lot of work. Some folks don't realize they repeat themselves but using different words does not change the overall meaning that ends up being the same. You clearly know infinitely more about Solar than I as I am still learning and have yet to invest in my first system. My Solar needs are small at the moment but will grow as I am able to afford upgraded equipment to expand. I've been researching and watching videos over the past several years now and I've found your videos to be of the most use thus far. Again your content is great it's just you tend to repeat yourself over and over and over which makes for a very long video. When you over explain it's more akin to spoon feeding your content rather than just putting it out there and letting use eat it at our leisure or pace. Please do not take my comment as harsh but rather as a playful kick in the pants as I mean no harm. It might not be a bad idea to put what you would invest in as a baseline. You did mention that flexible panel with a high efficiency rating as an option but dollars to cents matter to most folks these days. Sure it would be nice to have our cake and eat it too plus pick out the toppings but Life is not like that many times... Cheers mate, keep up the great work....

[@darryldrax606]

Thank you for the information 👏👍😉

[@aniefiokudoh29]

Hello Justus, I am very impressed by the way you explain this concept of wiring solar panels both in series and parallel. Aside from the different classifications and benefits with disadvantages of types of panel. I have learned a great deal of knowledge. Respect Botherly!

[@reptilesmiami]

Where is a good website to buy solar panels and all the equipment . Also can you leave links. I want to solar power my home

[@DuetJustusFam]

Hey! I just posted a video on our personal solar panel setup and here is a link to the eBay seller I purchased my panels from (goo.gl/WdPnn5). Hope this helps!

[@michaelward402]

A few misconceptions but a well produced video nonetheless. Love the name lol I did see in the comments someone saying that there are diodes across the panels to stop the shading loss, this is quite untrue, they are there to protect the panel from reverse currents which may destroy the panel. This is silicon and the way a solar array works is not dissimilar to a transistor. I think the second misconception is that the panel has been taken as a single solar unit, whereas the panel is an array of cells, configured in series and parallel. Those cells that are shaded will of course not turn on and thus will not conduct and generate electricity. A simplistic way to think of this, is in terms of there being a row of cells in series (~18-22), to give the panel Voltage, and rows of cells in parallel to give the current. Now if you imagine that the top half of a panel is in shadow and the bottom half is not, then the panel will still generate a current albeit less than a full panel. So if each row generates the Voltage, then covering a row up will turn the power off and any row in sun will generate power. You can easily see this when you look at a panel. The cells are in a series and parallel matrix, so even if you cover a top corner of the panel, the rest of the cells will still generate power. Hope this helps.

He keeps saying "silicone" but he means "silicon." Silicone (long "o" sound) is the squishy, soft gel; silicon (short "o" sound) is the hard, brittle element.

[@nescopakistan1208]

Thanks for presenting the brief on basics of solar panels

[@bradelinagomez1161]

Oh, and available today are systems that use either power optimizers or micro-inverters, both of which change the wiring possibilities along with removing restrictions in layout and remove shading issues. You should also be aware that the voltage and current are not fixed. An example factor in varying voltage is temperature, which can change significantly throughout the day. One other factor that should be considered is there are lots of factors that derate, or reduce, the current carrying capacity of wires and cables.

[@dannylloyd-jones5758]

Best info on solar for off grid! Thanks for all the effort it takes to put together these videos. Really appreciate it.

[@G55-j9z]

Great Video, and a very clever person, I tried to get my panel supplier to explain why I should connect them his way and I got baffled with jargon. Thanks for posting the video. Thumbs Up.

[@BluegrassHiker]

Great delivery of information. Working on my own electrical plan for our van. This series helps a lot. Thanks!

[@markchapmon8670]

I understand your focus is on RV's. If you are considering a home system though, don't forget racking costs. The racking materials aren't freebies and the poly panels larger footprint require more space, which equals more racking materials. If roof mounting, you could likely place more rated watts of solar on your roof with mono panels. Good explanation overall.

[@iron0xide974]

This was helpful. Building my own solar power system for an off grid cabin.

[@jeffs7139]

GREAT JOB !! I finally understand how all this series vs parallel stuff goes. Best and easiest to understand explanation I've ever seen ! Thank you, thank you, thank you.👏 👍👍

[@Stonewillow2]

Nicely done. Clear and concise. Lots of good usable info that could be applied to a number of different applications!

[@DGill48]

A pretty fair explanation. Retired, but I taught high school science, mostly Physics, 40 years.....Remarkable that most students don't even have to take Physics to graduate high school. The majority of graduates don't know the difference between an amp and an ohm.........and don't want to, either.
