You can get a commercial 100W solar panel here (affiliate link): http://rover.ebay.com/rover/1/711-53200-19255-0/1?icep_ff3=2&pub=5575101368&toolid=10001&campid=5337606358&customid=&icep_item=391726701593&ipn=psmain&icep_vectorid=229466&kwid=902099&mtid=824&kw=lg
You can get individual solar cells here (affiliate link): http://rover.ebay.com/rover/1/711-53200-19255-0/1?icep_ff3=2&pub=5575101368&toolid=10001&campid=5337606358&customid=&icep_item=222571000661&ipn=psmain&icep_vectorid=229466&kwid=902099&mtid=824&kw=lg

In this episode of DIY or Buy I will show you how I created a 100W solar panel by myself. Along the way you will learn how to wire up solar cells and how they are usually wired up in a commercial solar panel. At the end we will then evaluate whether the DIY version is cheaper to produce.

    1 second ans: buy

  4. Febry Pulungan on December 14, 2020 at 10:20 pm

    A honest DIY, the winner is from factory, but if keeping learning and improving i’m sure u can beat that commercial solar panel

    we havent money to prepare. bt we suffer interest wotching these. tax lot

    Verry interesting!

    In my country
    Solar panel isn’t popular

    Your using the wrong words.

    Cheap speaks on quality, inexpensive speaks on price. If something is cheap it means it’s poorly made. If something is inexpensive it means it didn’t cost much relative to some implied factor such as the potential purchasers budget, or comparable goods or services. It’s a common mistake, in the U.S. we almost exclusively use the term cheap for both. We are robbing the word of it’s power when we do that though, hence why I point it out to people.

    These words have power? Yes…

    When you tell a maker, builder, inventor, manufacturer, etc that their item is cheap they should take heavy offense motivating them to improve, but instead they just interpret you as saying they have low prices, and are happy motivating them to slowly raise prices to meet expectations.

    Take bake the power…

    Take bake the power of the word cheap so that you don’t have to resort to phrases like low quality, hunk of junk, POS (not point of sale *wink wink*) etc. These phrases tent to make you seem lower class thus pore thus not the maker/manufacturers problem, thus they are not compelled to improve … for who… someone who couldn’t pay them anyways? No you want to come off as higher class so they are motivated to improve for a chance at getting some of that cash you must obviously have.

    Understand now?

    See why ‘inexpensive’ has power? Because it gives ‘cheap’ back it’s power. It also carries it own innate power too, but I imagine, if you got this far, you can reason that out on your own, if not explaining it would likely be a fruitless endeavor.

  11. Corentin Lucas on December 14, 2020 at 10:31 pm

    Good video to learn how a solar panel is made !
    One point I just doubt of if that the DIY version produce the same power as the BUY version because the DIY should suffer from more losses (more resistive loss from the DIY soldering, the optics loss from the resin (not as good transmitter as glass+encapsulant) 🤔

  12. Mojibur Rahman on December 14, 2020 at 10:33 pm

    Ans : buy

  13. Jack 180 on December 14, 2020 at 10:35 pm

    Why not weld the frame?

  14. OmegaMetalic on December 14, 2020 at 10:35 pm

    Don’t know much about electronics what size diodes do I need to get?

  15. Dipti Soni on December 14, 2020 at 10:37 pm

    Is this possible for you to create a 5 kilo watt solar system as DIY because in our village electricity always goes off and purchasing it is too costly for us
    I want you to please comment

  16. jimbobbyrnes on December 14, 2020 at 10:37 pm

    once you seal it in resin you remove the only upside of diy solar panels which is the ability to replace a broken cell and save you buying another full panel.

  17. Michael Mills on December 14, 2020 at 10:38 pm

    Yeah this settles it. Sorry i skipped to tue end. I know how to build one..thx just the same. Your price compairison chart helped tue most. For 136 American USD, I can get 100w w a free charge controler and box. That seems to he the best move. Anyone ever get one from Amazon akd had it LAST more than 1 yr? They degrade over time.

  18. Cesar Moreno on December 14, 2020 at 10:38 pm

    You could use a recycle window, the efficiency isn’t affected, I tested 👍

  19. Rashad Abdullah on December 14, 2020 at 10:38 pm

    Didnt need the aluminum imo. Just a wood frame to hold in the epoxy wouldve been sufficient. The epoxy also was sufficient to waterproof. The silicon was not needed. Still tho with all the time needed to do everything it really is better to buy unless ur like an engineer on say a mission out in the wild where u needed to b creative and resourceful.

  22. Manfred Behrens on December 14, 2020 at 10:42 pm

    Wenn du das ganze Material und Zubehör kaufen musst ist es bestimmt billiger wenn du das gleich fertig kaufst.Garantie und viel Zeitersparnis hast du auch noch ,also nicht gut selbst zu bauen.👎

  23. lloydrmc on December 14, 2020 at 10:42 pm

    Charming, entertaining, and informative.

  24. Daniele G on December 14, 2020 at 10:43 pm

    Fully agree! DIY only for very STRANGE shapes!

  25. Axel Szmidt on December 14, 2020 at 10:44 pm

    how about a flexible solar panel || DIY or Buy?

  26. Sanford Fahy on December 14, 2020 at 10:47 pm

    Why should solar cells exposed only one side to light when mirror can reflect light to it as well?

  27. Juan Bautista on December 14, 2020 at 10:49 pm

    excelente video gracias

  28. Ak Baloch on December 14, 2020 at 10:50 pm

    Decide yourself which panel to buy after seeing this

  29. karzygijose on December 14, 2020 at 10:51 pm

    That’s a interesting smart wattage meter you got there got the item name or app?

  30. minh vo on December 14, 2020 at 10:54 pm

    Hey GreatScott, can you help me make a solar panel?

  31. Der Goat Highscore on December 14, 2020 at 10:54 pm

    Was hast du, studiert wenn ich fragen darf und was machst du beruflich?

    Putting all the solar cells In sires gives me anxiety

  34. Kasamahan Tv on December 14, 2020 at 10:58 pm

    Diode does not needed if you have a solar controller charger

  35. Gustavo Cardenas on December 14, 2020 at 11:01 pm

    I love your videos! subscribed.

  36. Young Cebulak on December 14, 2020 at 11:01 pm

    In my country i can buy 11yrs old solar panel with 90W for 25PLN = 7$. It’s good price?

  37. Carter on December 14, 2020 at 11:02 pm

    Before watching I predict that the store bought one will be cheaper because the company probably pays a fraction for the materials due to buying in bulk.

  38. Rashid on December 14, 2020 at 11:03 pm

    It’s like comparing a diy to a giant factory’s production and economies of scale, it can never be cheap. Except if you get free parts and don’t count labour

  39. robshnob123 on December 14, 2020 at 11:04 pm

    This gave me an idea…have a roll out solar panel that rolls up like a tarp from a track system, to protect it from the elements…

  40. Daniel McArthur on December 14, 2020 at 11:06 pm

    Well one tip I would suggest for people is when you get a new adhesive tube and you have to cut the plastic part to open it. Cut it at 45°. Much easier to control the caulking. Also don’t constantly squeeze the trigger. Pull it till it starts coming out than just do a full line.

    140€ for 100w when can easy buy 250w for 80€

  43. Brian Brewster on December 14, 2020 at 11:07 pm

    The big question is this: how many of these 100-watt panels does the average homeowner need to install before s/he is grid-free? I read the average consumer required 30 kW per day or 1.25 kW per hour. But we only get around 3 -5 peak hours of sunlight and mostly around noon when our sun is direclty overhead. Unless you send excess electric to the grid, you will then need an efficient storage device. And don’t forget you will need a very expensive inverter to convert all that juicy DC into AC to run everything in your home. All told – your investment will be a minum of a few thousand dollars.

  44. Kevin's Solar Adventure on December 14, 2020 at 11:07 pm

    Awesome dude. You rock!!!

  45. Rs Stivo on December 14, 2020 at 11:07 pm

    make inverter to change DC to AC 230v

  47. roberto pasquali on December 14, 2020 at 11:10 pm

    try to make a solar panel with led the most efficient led is the yellow

  48. Angel on December 14, 2020 at 11:13 pm

    Here you get a powerful lithium battery’s for any tiny home ! @t

  49. Bosko Vaskovic on December 14, 2020 at 11:14 pm

    It depends. In my country you can buy solar panel for about 200$ for 100w. But if you order solar cells from China, you can diy for about 80$.

  50. ACF on December 14, 2020 at 11:14 pm

    DO it 5x and I bet you can do it better!
