But, just in case you went and bought untabbed cells to save money, let us explain what has to be achieved
. Firstly, you need to solder a tabbing strip to the "sunny-face" of each and every of your cells. There are two main ways to do this, both fiddly. You'll solder the strip straight to the mobile with flux or, pre-solder or "tin" each strip and then solder it to your mobile. The theory is to get a connection that is solid the solar cell or you won't move current. Solar tabbing ribbon typically comprises of 10-15 micrometers of solder alloy, commonly SN60 (60% tin and 40% lead) coated on copper strip, note this contains lead. I'd get without pre-soldering the tabbing strip as I'm a bit lazy. In any event, use flux to your the big shiny strips(the coach bars) on the front "sunny-face" associated with cell. Lay the tabbing strip over the bus that is fluxed along with a flat tipped soldering iron, operate slowly down the strip. Extra hands are good right here. If you did a bad work, the tab strip
will peal straight off. If done carefully, the tabbing strip shall bond to your bus club. I recommend exercising for a cell that is broken some extra strip to get a feel for the soldering. Since you will find usually two of those on each solar mobile, there is a lot of fiddly soldering to complete. Now can you understand why it is better to buy tabbed cells?
Now to another location action, connecting your tabbed mobile to its mate, the next cell. Basically you will be soldering the free end of the top "sunny-face" tabbing strip towards the bottom regarding the next cell and repeating the method down your sequence. Therefore, in the event that you didn't lay your cells out based on your panel layout, (age.g. 3 strings
of 8 cells), or whatever your design will be, do that now. Leave a space that is small of 1centimeter between each of those. This is a good clear idea to draw a template on some cardboard or Masonite to keep the strings neat and match the dimensions of your array package.

Did this cause them to become plumbers that are bad?
Maybe not with a shot.They that is long really good at there job.
Being a mater of fact, I was showed by them how to install pex tubing with out putting a kink in the tubing.
Inturn they were showed by me how to solder copper pipeline.
The result, certainly one of them utilized knowledge I taught 'em, while another forgot a few crucial steps and caused a major leak.
