-I will solder five cells into one panel and use that in my first resin-potted prototype.

+Soldered up one five-cell array.
+I used some fine copper wire to join the cells. I used leaded solder, a chisel tip, Chipquik SMD291 flux and 270ºC. I dipped the wire in the flux and laid it across the contact on the panel, wet the iron tip with a good amount of solder then swept across the copper while I held it in place. Once I got my technique sorted it was pretty straightforward.
+Holding this cell in diffuse sunlight gave 2.7V open circuit voltage.
