Soldering solar panels without tin
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.
