How To Install Harbor Freight Solar Panels Part 2

so here's a close-up of the panels there's the old the other said that I have made yesterday and here's some new panels that I just made and as you can see I used the like bolts with the washers put them right in between each one one on the top one on the bottom and went all the way through and then these corner braces bent appropriately on the wise with a hammer so they hold the edges these ants downs for the wind can't move that up and then about four inches from the from this edge it's where I start and what I do is I mark one inch off the top of this board and line them all up that way if you line them up one inch from the top and kind of keep that then they're gonna be you know pretty close pretty even back here so you can see they look pretty pretty good there now the junction box that I was talking about earlier I mean the process is just putting it in so what I do is I got one that's just fully closed putting a twin screw here in here you should actually use a 105 raised two inches a little bit too long but that's okay and we're gonna put the bus bars in here she can see here the wires are already hooked up so here's a wire from the panel on the left and on the right you can see that the positive on one panel goes to the negative of the other one and that leaves you with a positive from one panel and the negative from the other panel available that's 24 volts if you put a voltmeter across these two you should get 24 volts so that's one string and the next string is again like that positive to negative right so I got this one wrong this one is wired in parallel so I'm gonna have to redo that one that would give me 12 volts so this one is who are correctly I'm glad I rechecked so here's a positive and a negative with a resulting positive and negative and they said if you put a voltmeter across that'll be 24 volts so I'm gonna go back and redo that one real quick and then I'll show you how we're going to put the bus bars and string them all up there thanks so here's the middle string fixed now we have negative to positive and we have then a result in negative and positive which should have 24 volts now we're going to bring those strings into this the strings into this junction box and here's the bus bus bus bars that I was telling you about I use a four position one one for the positive one for the negative we're going to screw them right in here and we're gonna put our wires in there so I'm gonna show you how that looks in just a minute so this is the junction box now wire you'll see that there's three strings of wires from each one of the three strings that parrot strings that we created and the two bus bars are installed with wood screws and I have all the positives going here or the negatives going here and then we're gonna go with 10 gauge wire from the pot from the negative and the positive out of this hole here and you see that there's two 3/8 inch holes drilled we're gonna put a black and red 10 10 gauge wire to go here and then that will tie the string to the next string and then from there to the batteries the basic tools that you'll need are a were stripper slash water cutter I like to use a dedicated pair of water coders just dikes not to do my water cutting and then a pad tip screwdriver to tighten and loosen the bus bars and then a Phillips screwdriver to do everything else other like volts depending on what size you have you know what size you buy I bought a quarter inch by two inch lag bolts and so these are quarter-inch heads on this I'm sorry not quarter-inch there are 7/16 hex heads on these like walls and but they're quarter inch shaft and two inches long and that's exactly what you need to get this project going now totally matter of closing up the lid on that junction box throwing them up on the roof and we're gonna be good to go here in a little while so you can see the roof it's a metal roof all around the house and these pieces here are gonna lay in between the valleys of that and then those are about almost a foot across in between the ridges so I cut I'm gonna cut pieces that are 10 inches wide to give it support in the middle so that's it for now thanks for watching and I will post more as soon as we get him up on the roof take care
