In this video tutorial, I will tell and show the whole process of soldering tinned copper strips to solar modules (or solar cells).

Briefly describe what is needed to solder strips to solar modules:

• The first thing we do is prepare the workspace.
  
  1) To do this, you need to prepare a flat surface where you can be without fear of putting the solar module. In the video, I used a piece of fiberboard sheet.
  
  2) Next, you need a soldering iron - not more powerful than 60W, because the solar module is afraid of overheating.
  
  3) Get a flux in the form of a felt-tip pen and solder.
  
  4) And the most important point - put on a medical glove on one arm (usually the left). This is necessary so as not to leave fingerprints on the working surface of the solar module (solar cell). Fingerprints can degrade their effectiveness, and aesthetically the modules look better without them)).
  

• Then we tack on the contacts on the solar module.
  
  We process the contacts with flux, we take a small drop of solder on the tip of the soldering iron, and without pressing in the place of tinning, we quickly process the necessary contacts with solder.
  
  
  Attention!:
  
  

• After tinning, solder the tinned copper strips to the contacts, using the tips above to avoid damage to the solar modules.
  

That's all you need to know when working and soldering modules.
