Step 2: Assembling the Solar Cells

Next, while my first coat was drying, I started to work on assembling the solar cells. The best way to learn how to assemble the solar cells would be to simply watch the video. A quick overview of it is, the bottom of the solar cell is the positive side, and the top of solar cell is the negative side. I wanted to connect the solar cells in series, with a total of 36 solar cells, which will give me 63 watts. I used tabbing wire with a soldering iron to connect the solar cells together. For my panel I had 3 strings of solar cells. To connect those strings of solar cells, I used what is called a bus wire. The bus wire goes at the end of the strings to create one long string, however, curled up in a way like a snake. Again, for step 2, I recommend you watch the full video (Part 3) to understand how to work with the solar cells and how to check the voltage/current.

<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>I really like your instructable I am almost at the end but it seems that you never explained how to wire the junction box to the charge controller. My junction box has what i believe are mc4 connectors. I can recommend <a href="http://batteryrecover.com" rel="nofollow">This guide</a> for everyone who need energy for home devices. It's really work good. </p>
<p>well, great, it's no longer free, you have to pay for premium service to download the instructions! </p>
<p>Sun oriented vitality is commended as a boundless fuel source that is contamination and regularly clamor free. The innovation is likewise flexible. For instance, sun based cells create vitality for far-out spots like satellites in Earth circle and lodges somewhere down in the Rocky Mountains as effortlessly as they can control downtown structures and advanced autos.</p><p>Be that as it may, sun powered vitality doesn't work during the evening without a capacity gadget, for example, a battery, and shady climate can make the innovation inconsistent amid the day. Sun powered innovations are additionally extremely costly and require a considerable measure of land territory to gather the sun's vitality at rates helpful to loads of individuals. </p><p>Regardless of the disadvantages, sun oriented vitality utilize has surged at around 20 percent a year in the course of recent years, on account of quickly falling costs and picks up in proficiency. Japan, Germany, and the United States are real markets for sun oriented cells. With assessment motivators, sunlight based power can frequently pay for itself in five to ten years.http://www.worldsolarpanels.com/</p>
<p>Actually we can recondition any batteries - <a href="http://batteryrecover.com" rel="nofollow">here is video</a> and charge from solar panels too. It's almost free source of energy.</p><p><a href="http://batteryrecover.com" rel="nofollow"><br></a></p>
<p>I Made it</p>
<p>hi good day! I'm having my study now about how to make more solar energy like we have today... but I have some concerns regarding the present solar panel today... I hope if you are not busy I would like to get an answer about this concern... how much heat does the solar cells withstand?</p>
<p>Great Stuff! Thank you for the instructable!</p><p>It's also great to see another Robert Smith rocking it!</p>
<p>Hi - I was wondering if you used a battery and if so, what kind? What did you use to charge with it, and what gauge wire did you use? Also, did you use a charge controller, blocking diode, and power inverter? Thanks!</p>
<p>In part 7 1:40 when you said &quot;you'll be goin' back to home depot&quot; I laughed so much as I have been there done that. for everyone ; this is a fantastic real world video!! But bar none Robert has laid this out well and while it is a tough project for almost anyone as those cells crack on you just at looking at them!! A Vote for this man!</p>
<p>Did you use by pass diode ? or Just blocking diode ? Ty</p>
<p>The most well documented project I've seen. You cover the whole thing from soup to nuts as they say. You put a LOT of effort into this. Very well done!</p>
I commend you on your adventurous ambition. Thank you so much for creating these videos and sharing them to the public for free. I'm looking forward to see if you make more videos and if not I wish you the best in life. I will make sure to post again if I am successful building a solar panel.
<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>
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>
where can i get solar cells ????? pls reply i need the answer please:(
<p>ebay is the best place probly ms solar</p>
You can get them from ebay. Just type in solar cells and you will be on your way.
thanx a lot dude...:)
They are easy to find and buy, I have had great success building my own solar panels for my house, there is so much great info on this site for you to apply.
<p>Hello Robert thank you for this article,I'm really interested and God bless you for sharing to us,i will try and build my own.Thank you</p>
Thanks for making this site <br>I was wondering do you have to paint it white and do you have to use the pegboard bored
<p>how much di you pay for just the Solar cells? I already have a couple of SLA batteries, an inverter, and a controller. I want to make a ~50 watt panel, what is the estimated cost?</p>
<p>The link to your site seems to be a dead link, where can I find the video series you mentioned?</p>
