Step 5: Soldering Bus Wire

Next, after hooking all 3 strings of solar cells up in series, I was ready to get my 22 gauge wires (red and black) ready for soldering. On the ends of my leads from my gauge wires, I connected some connectors to make the process of soldering them down to the bus wire a lot easier. Watch Part 7 of the video to see how I went about doing that.

To help give the inside of the solar panel a nicer look, I used 2 strips of wiremold and ran the wires inside those. This is also seen in Part 7 and Part 8 of the video. Afterward, I took the panel outside in the sun to test the voltage/current of the whole panel to make sure I was getting 18 volts and 3.5 amps in an open circuit and short circuit.

<p>The solar stirling plant is the most powerful way to generate free electricity. It generates over 12x the power of regular solar panels in less space and for less money! Imagine lowering your monthly electric bills by 30, 40, 50% or more. <a href="https://solarstirlingplantblog.wordpress.com" rel="nofollow">Free video reveals</a> a crazy secret to cut your electric bills by 75% (or more) In Just 2 days!</p>
<p>I used to have big problem finding effective ways to build my solar panels and maximizing my solar power.But I am getting better result now, after I stumbled upon this excellent guide I found <a href="http://the-natural-treatment.com/Solarpanel.php" rel="nofollow">HERE</a>. It was a godsend. It gave me great Solar Panel tips and showed me what I was doing wrong before.</p>
<p>today same panel make about 40-60 $ wery expensive if cost 400 $ same prize u can buy ready to use panel today 2016. 400 $ can buy about 400-800W panel now.</p><p>diy u can made 400$ 1000W panel or 2 pcs.</p>
<p>I made my first solar panel 2 weeks ago. I used 'inplix' plans to make it. Working well. I can recommend it</p>
<p>I took the inplix package yesterday. I'm gonna make solar this week :)</p>
<p>Did it work?</p>
<p>how much amps</p>
<p>Good job.</p>
<p>I looked at ebay. Panels etc. for 75 watts was USD$30.00. A company in Miami is selling 250Watt panel for $0.45 per watt.</p>
<p>I heard that there is Mercury in solar panels and that is a fact.</p>
<p>Please do not chew, ingest, or otherwise insert the solar panels into your body. </p>
<p>So true xD</p>
<p>Depends on what panel you are making; many are Hg free</p>
<p>Because in most cases, (depending on what/where/how your going to be using it) You won't be covered by insurances or your municipality will not allow its installation unless it has been built, installed and certified by a pro... Especially if it were to be tied into the grid. (Which by the sound of it you wouldn't be doing) Unless you're putting it in a cabin up in the woods or some place remote.. Fine.. </p>
How long would it take for someone to make one once they got the hang of it? Do you know about how heavy it was?
Which solar cell and Amt of solar cell needed to run a room
What's an Amazon video tutorial.
Doesn't plexiglass discolor over a fairly short period of time being exposed to the elements ? Thanks.
<p>For the record check around here are a few </p>Acrylic sheet/pmma panel
So, I'm building a panel, what should I use as a front glass please? Thanks a lot. Robert
i'm not quite sure how you're getting your tabbing wire to stick; i've been using solder on mind - front and back of the cells - and its not only coming off but it's tearing off the contact on the negative side and not sicking when i try to reapply it. did you get pre-tinned tabbing wire? am i just stupid? i cant get it it work (or at least stay on). bty - you're videos are amazing. i really appreciate the hard work :)
<p>no your not stupid i made this mistake and you need a rosin flux pen, it cleans the surface of the area were you are trying to solder. look up #186 flux pen on ebay</p>
<p>Flux pens are used to aid the situation not a permanent fix, solder, rods, iron still need to be cleaned with alcohol. Want to be #1......want to be successful, i'll tell you a secret that nobody will figure out till i open my mouth. What the heck i'm an educator.</p>ER209 stainless steel solder wire. It uses chromium
<p>Not bad, not bad mate. I made my solar panel too. check for http://inplix.com if you want to know more</p>
Well sometimes it can be a result of the type of tabbing wire you have and the type of soldering iron you have. I noticed one time when I bought some tabbing wire off eBay from a seller, the tabbing wire was a lot thicker than the tabbing wire that came with my solar cells (bundle purchase). And I too noticed it was harder to solder that thicker tabbing wire onto the solar cells and I was forced to put some solder onto the tabbing wire and then solder the tabbing wire down. But I had a basic soldering iron too, so the heat required to solder that thicker tabbing wire down could have played a factor, I'm not sure, but I'd recommend to you just to ask the person or company you buy it from next time what type of soldering iron do they recommend and is the tabbing wire made for the type of solar cells you wish to solder it too.
<p>cool work</p>
<p>hi u soldered the bus but u did not tell us why the bus is different on both ends, and I did not see were the negative wire is soldered to !</p>
