Loading ...A solar panel costs ~$80, and contains about 20gm, or two thirds of an ounce, of silver. $40 of silver. That is a huge proportion of the cost. If the silver cost rises to $400 per panel, existing silver substitutes, resulting in slightly larger panels for the same output (i.e. less efficient) would be the standard long before it got there.
Likewise with batteries. Apparently the Samsung battery pack would us a kilo, 31oz, of silver. Currently $2,000 a battery pack, new price $20,000 (before manufacturing costs which include cobalt, nickel, copper etc.). No deal.
$600 is only sustainable if it is for investment purposes, as protection against currency debasement, debt default, yada yada yada, and I’m happy with that thought.
Looks like the writing is already on the wall. Actually more efficient than silver.
