Re: Soldering to solar cells


>Why are you using copper wire to solder to solar cells?
I would use wire for this application because it's flexible in more directions.  I prefer #28 over #30 because it withstands more nicks and bends.  Ribbon is used to make encapsulated panels because it keeps everything thin and helps keep the circuit from moving around during lamination.  Fortunately, it's also easy for automated soldering machines to handle, as John B. noted.
