How to make a Solar Panel – Wiring, Soldering, and Cell Layout – Explained Simply!

hey there so in my last video I went ahead and showed you how to take these untap solar cells at the little metal tab into them this video I'm going to go ahead and show you how to hook up the tab solar cells into long strings so we can make a solar panel out of this here's another quick shot of it in brief flip over the panel like that the white areas are going to be the positive connections and the tabbing wire is always the negative part on the solar cell I think of it as like a solar battery and you just line them up slip another one like that so it looks like that then there's going to be six solder joints just solder this negative tabbing wire here here and here also here here and here and I'll show you that in a second then you just keep going a few minutes later you'll have that encapsulate that behind some glass and you got a solar panel okay here's the first 12 I'll set up for the first panel I'm going to do three panels 12 cells per panel makes a lot easier than doing one big panel then you just hook the three in series okay and this is how you solder one panel to another these are the positive connections on the back and all I'm going to do is put a dot of solder in each of those three spots and there so six dots the solder to start or care like that then just set this over top perfect and you do these three see how that melts right over it okay just like that that's all you have to do to connect the cells together you the next thing we need to do here is we need to connect the negative of this one to the positive of this one so we can keep the continuity of the string of panels so that's where this bus wire comes in we're going to connect a piece of bus wire across the negative terminals here and over and then we'll put two pieces of tabing wire along here that will connect to okay I'm now going to go ahead and solder the short pieces tabbing wire onto this panel right here it's about three and a quarter inches long just like that same thing on this side and lastly the front lawn here all right perfect okay so I cut those ends down so these are the negative from this panel this is the positive from this panel and all you have to do now take this bus wire which is just a fast piece of the same type of wire lighten it out and we're going to solder it straight across like that we just have to solder here here here and here okay remember not to panic if you make a mistake or anything inside of the wrong thing can always desolder stuff you can always take out the panels I broke a couple just making this one how to take them out and put new panels in okay and here's a close-up on the bus wire from the negative and negative to the positive and positive so it just keeps the string of panels going on the start six down over six up okay here's the panel outside for a test run see if we're getting the six volts out of it 6.38 6.42 do now is encapsulated into a case now to hook this up to four twelve volt charging you want to make three of these and hook them in series but that's a hell of a lot easier than making one giant panel and moving that around that will give me my 18 volts when i hook them in series and that'll be perfect for 12 volt battery charging I decided it's better to go with this modular design and make three at a time that way if anything goes wrong with one of them you just have to replace the one little panel kind of like the Harbor Freight ones Jen you get the three panel set you could think of this as a three panel set too and if you just want to use one or two panels you can do that too these twelve fit perfectly on a piece of glass sixteen by twenty so a very common piece of glass you can buy for about five bucks at the home stores and you'll be able to make one small panel this will be a six volt panel I'll make two more so I'll be a total of 18 volts which is what you need to charge a 12 volt battery system
