Type of Solder? High Tin% or Silver
Which means using tin-silver instead of a lead solder would be a 1.5% better. If the wires (and other stuff) are 95% of the resistance, then you''re at ~0.75%; if it''s 99% then it''s ~0.15% So I''d use what works best for the manufacturing - it''ll save time which is probably worth more than the extra losses from the small increased resistance.

Soldering and Metal Roofing
Soldering is a metalworking process that joins metals together with solder via heat. Solder is a filler, nonferrous metal that melts at a temperature below 840 F below that of the metals to be joined. After heating and melting, it hardens quickly, which secures it to the steel. The filler metal is distributed between the closely fitted surfaces of the joint …
