The problem with replacing silver with copper in anything electrical is silver will always be better. From what I know of solar panels they are only getting ~5 year lifespans with copper designs vs 25+ years with silver AND the power density is a lot worse (ie need more space per watts). For certain products like solar panels it is hard to see people willing to get the fridge planned obsolescence 5 year treatment when they were used to 20+ years before. But for certain industrial usages you could see it being an option if it was cheaper and they only needed them for a few years anyhow.

Good call. Surely it's cheaper to pay the extra costs for the small amount of silver in the panels than the labour costs of replacing and disposing of the panels every 5 years.
