Homemade Solar Panels Diy tutorial, complete build How-To Part 1

well hello everybody we've all been asking for a new tutorial of some sort I've been getting a lot of requests and feedback lately and possibilities of new how-to videos well I dunno I have a few unfinished projects they're not unfinished because I don't want to unfinish them I mean yes I don't want to finish them it's because I have not had a opportunity and or the correct equipment to finish things but I have a good one for you and I was actually it was actually requested how to build a solar panel so we're gonna be building solar panels here pricing will be able to get under a dollar a watt ideally I think we're gonna be hitting about $0.50 a watt approximately using repurposed materials like such as the actual paneling is a storm window that was going to be thrown out it's nothing wrong with the window so they could still be used today but with all the new upgrades the higher efficiency windows not needed so a few materials you're gonna need get your hands on a used storm window ideally you're gonna want one with an aluminum frame do not use a plexiglass window or any kind of plastic based is even the ones that are supposedly UV stable will eventually yellow and fade in you know milky colored while sitting in direct sunlight all day you want a nice glass one tempered is always best if you can find it aluminum framing works the best you want some rigidity and that's what I'll be using they're gonna be a few other steps to it I'm gonna be using some plastic board from the last presidential election I'm sure you've all seen those signs on the side of the freeway during the presidential election vote for this candidate vote for that can well I managed to get my hands on about a hundred of them that we're gonna get thrown out I was hoping I'd be able to peel the lettering off but apparently it's printed directly on I wanted to peel the lettering off because we have a vinyl plotter and could put our own sign on it that stuff's not cheap but you can use a host of other things feel free to use plastic backing to it but the side facing the Sun you do not want plastic so some materials you will need obviously you're gonna need solar cells they're gonna be using six inch by 6 inch solar cells each cell each one of these cells is one-half of a watts 0.5 watts excuse me Oh point 5 volts 1/2 volt and each cell is approximately 5 watts and I'm gonna have to measure it out yet but I think I'm gonna do somewhere around 22 volt solar cells I have three of these glass paint panes then I have a few smaller glass panes as well some other things you will need they're gonna need a soldering iron and you're gonna want it at least a 40 watt soldering iron most soldering irons come with a what's called a pencil tip it's the tip that comes to a little point for the purpose of tabbing solar cells you want a chisel tip because we're gonna be dragging it across these little lines on the cells just spread just spread the solder out so you can get a nice kit I got I got this nice kit satury soldering iron and real nice just screw it right in and you're good to go about 10 bucks there maybe if I start making a lot of these panels I might get one of the more adjustable temperature soldering irons but as a basic this was an upgrade previously I just had my dollar store ones which for just doing minor electrical soldering of wiring and motorcycles and scooters a 20 watt was just fine but to be able to keep up with the heat long enough to spread the solder all the way across it was highly recommended to use at least a 40 maybe a 50 or 60 depending on side the solder type used we also have we're also going to need bus wire this is the wire that connects rows of cells together and then we also need tab wire a tab wire is what goes down the length of the cells and then connects the positive to the negative sides this is the negative side in the backside is usually the positive side so basically what's going to happen in what's called tabbing is where you lay down the wire and you're gonna want it twice the length of the cell and I lay down the wire solder to one side and then that would go underneath the cell next to it and would then run down the length of the backside because you're going from negative to positive or from positive negative positive negative positive negative from cell to cell to cell voltage you put them in a series to build up the voltage and then you put a group of series of cells in parallel to build up the wattage and like I said each sells about 5 watts four to five these were supposed to be great a sells but for the price I get them for they're not quite they do have some blemishes and defects on them for the price that I paid for them the blemishes and defects are fairly negligible and will not affect it's all cosmetic you will not if it should not affect the output of these cells any noticeable way maybe one or two percent of its maximum output so okay so say a cell is supposed to put out five watts it might not put out four point nine or four point nine five Watts salt like I say negligible and considering that we're gonna be building a solar panel for less than right around fifty cents a lot maybe tha less depending on the cost of materials now the the I I usually get these in package deals with the cells the package usually comes with a tabbing wire the bus wire it also comes with and you're going to need a flux pin know this now the solder is flux listen so much easier to use a flux pin and what you do with the flux pin is it goes down you draw a line across the cell on the tabbing line it's having marks there and then you put down a little dab of the solder but you're also the kits come with diodes backflow diodes and what these do is is keep power from going out back out of the cell so say you had your instead of charging or instead of feeding into the grid you're gonna be charging a battery bank well you put one of these in the line between this panels on the battery bank so that way when the Sun Goes Down and instead of power moving from the panel to the battery otherwise the bat once the sun's down the power go from the battery into the panel and the panel would then radiate that power as heat which is kind of a neat idea as a heater but it'd be a rather expensive heater for how much solar panels cost these are fairly cheap you can even get them at RadioShack very low cost now this kit had 1,000 watts worth of solar panels which would be 250 cells and let's see so we got what do we got covered here we got solder iron tabbing wire bus wire solder diodes flux pen remember chisel tip on the soldering iron and of course your cells now now cells are very fragile so be very careful with them they do break very easily I broke this one just by almost gently contribute rying to pick it up I bent it just a little bit too much and that's what happened and don't toss these away believe it or not even this little fraction of a cell still can put out power this is probably a half watt worth right there you probably still get out of here and then this is all still usable so maybe instead of using it on a large panel use it on a smaller one small project of some sort and there we have it the next video I just want to get the preliminaries done so you guys can start shopping for your materials if you want you're more than welcome to message me I am selling the cell kits that have these having what the wire you know everything except the soldering iron for four hundred and fifty dollars I got to make some money on the deal all right and includes chipping and then otherwise you're welcome to find a specific source of yourself for the home eight panels don't go out and waste your money on grade-a cells you can get the ones like this with minor blemishes and defects rather cheaply because no matter how good you make it you're not going to get a homemade panel lasts as long as a as a factory built panel they're great return on investment though you usually you'll see about five to eight years life out of these before they start declining and it's usually due to moisture poorly sealed panels now there's encapsulants you can do but once you start adding all that you really bring up the cost then you might as well just go straight to a manufactured panel even the Chinese panel like that so I'll see you guys next video and any questions just post down below and if I have time this afternoon or tomorrow I'm gonna try shooting a video showing how to tab tab these cells which a lot of people are showing incorrect or poor methods of doing so I'm hoping to be able to correct that and show you guys the more correct way of tabbing cells so that way your tab wire sticks and you'll have a lot much much more reliable cell and I notice a lot of other people making these videos running their soldering I hear it's way too hot I'm not gonna name names but I watched a video where the kid said it's normal kid I shouldn't say kid could have been twenties maybe even early thirties I said it's normal for the solar cell to warp and Bend a little bit as you're soldering it due to the no that is not normal you are doing it wrong yeah I'm hoping to be able to show you guys a proper way of doing that and this video will even go as far as showing you not the most legal method due to all the regulations and inspections and permits that needed but we'll show you guys how to connect your solar cells to the grid and back feed that power into the utility and before I get heat about how dangerous it is this that illegal remember this video is going worldwide not every country has the restrictions and this that we do in the US and when do you not do illegal stuff done properly it can be just as safe as any other system although if possible I do recommend getting a ul approved grid-tie inverter and legally installing it to the grid I do not endorse any illegal methods of connecting to the power grid as people can and have gotten hurt and/or killed doing illegal hookups with other illegal stuff so on and so forth you get the idea that was my disclaimer you're responsible for your own actions no one else so I'll see you guys next video I better start uploading this because it's gonna be a few gigs
