- An overview of how we solder together our solar modules. Encapsulation will be shown in another video soon.
We have teamed up with a local company to make the C-60 spacers commercially available. All proceeds go back to the team for more research like this.

Excellent
Thank you so much for this video!
Bravo!
You could have just used the kapton tape as insulation under the busbar. It's not going to soak up moisture like the paper will and it can take a lot of heat.
Hello everyone,
I see you are soldering each solar cell, to the next one, using the provided dogbone. This dogbone interconnects all three tabs of the one cell as it has a vertical stripe in the middle. I would like to ask what would happen if instead of using the dogbone, someone will use 3 (three) independed nickel strips from the one (negative) tab of the cell A to the positive tab of the opposite cell B. What are the advantages and disadvantages of using each approach? Thank you.
Thanks for that info using 3d printer to create the frame for proper lining. I tried with dogbone that was a mess. Later i just used stripes, but now I'm wondering if dogbone actually helps to dissipate the heat when 5.5 amp passes through the connections. I think dogbone reduces it's resistance, so the overall power output will increase.
Which soldering iron temperature do you prefer for the dogbones?
Do all three contact dots need to make contact with the dog bone tabs? We got a batch of cells with the contact dots that are practically between the traces
What is the name of orange things that you used for spacing? Thank you
2:03 - The Weller is self-regulating. It regulates at the temperature you set on the dial.
The lead in the solder does not vaporize at normal soldering temperatures, and ventilation addresses the removal of flux fumes.
Hey, I'm doing a research project on this type of cell and I was wondering if you know a way to cut them and make contacts in the cut part?
Where do you buy the sunpower solar cells?
i have a solar wafer that seems to be divided into 4 quadrants at the back. i dont know how to wire this. would you know how to wire such?
hi have you ever worked with solar wafers that seem to be divided into 4 quadrants at the back?
Great tips and technique. Is it required to solder the full length of the bus on the common bus style cells or can the ends only be done like you do with these cells? Is the full length necessary to pull full amperage without damaging the cell?Thank you. What are you thoughts and experience?
I recommend soldering the full length of the tabs. Also I recommend fluxing the back of the tabbing wire and not the cells. Tabbing the cells results in flux bleeding on the cell. Here is a link to the only video I have of cells being tabbed. This was for our 2014 array. I'm not even sure why I shot this video but hopefully you can find it useful. ua-cam.com/video/9KLd7M0rtpI/v-deo.html
What temp are you guys setting your irons at?
Hi Jeff, we used a self adjusting iron for these panels but an iron set to 600-700°F should be good to solder them together.
I wish you talk louder because I had my volume all the way up still couldn't hear you. This might been a good video.
hi, what power of soldering gun is sufficient for that please?
Hi Gregory! We prefer to use a self sensing soldering iron for these cells but a decent soldering iron set somewhere between 600 and 700°F should be sufficient for soldering. The key is to not leave the heat on for too long as it will damage the cell if held for too long.
what is the spacing for these cells?
2mm
Boo! You never actually did end up talking about the encapsulation 😤
these guys don't know what they're doing, don't watch this, they make it way too hard
crappy vid. I cannot tell inside from outside. A closeup of the paper might have given me a clue to its purpose. etc.
